OPEN-DRIVE COMPRESSORS

These compressors are designed to operate with Refriger-

ants 12, 22, 134a, 502, or 507/404A. See Table 1.

Operating Requirements — Satisfactory operation of

a reciprocating compressor depends on 3 fundamental

requirements:

1. Prevention of excess discharge temperature.

2. Adequate compressor lubrication.

3. A clean and dry system.

Discharge Temperature — The temperature at the

discharge valves within the cylinders is a controlling factor.

Some cooling of the discharge gas occurs before reaching the

discharge stop valve, thus when water-cooled heads are used,

this cooling is greater than it is without water cooling. To pre-

vent excessive temperature at the compressor discharge valves,

the following temperatures, when measured immediately

following the discharge stop valve, must never be exceeded:

For nonwater-cooled heads . . . . . . . . . . . . . . . . . . 275 F max

For water-cooled heads . . . . . . . . . . . . . . . . . . . . . 250 F max

The approximate discharge gas temperature can be found

by using the following equation:

Where:

T2= Discharge temperature, F absolute

T1= Suction temperature, F absolute (including

superheat)

P2= Discharge pressure, psia

P1= Suction pressure, psia

N = Compression exponent of the gas (see Table 2)

Table 2 — Compression Exponent “N”

*For R-134a and R-507/404A refer to the Carlyle Compressor Selection

program (http://www.carlylecompressor.com/TechnicalInfo/Carwin.htm) to

determine discharge temperature. The selection program can also be

used for R-22 and R-502 in place of the discharge temperature formulas.

The value of compression exponent “N” depends upon the

properties of gas compressed, degree of cooling in compressor

jacket, leakages, etc.

To simplify discharge temperature calculations, the preced-

ing formula may be stated in the following form:

T2 = [(460 + T1) x C] – 460

Where:

T2 = Discharge temperature, F actual

T1 = Suction gas temperature, F actual (including

superheat)

Values for “C” at various compression ratios are listed in

Table 3.

Table 3 — “C” Factors

*For R-134a and R-507/404A refer to the Carlyle Compressor Selection

program (http://www.carlylecompressor.com/TechnicalInfo/Carwin.htm) to

determine discharge temperature. The selection program can also be

used for R-22 and R-502 in place of the discharge temperature formulas.

Example:

Refrigerant 12

Factor C = 1.33

Suction Temperature, T1 = 0° F saturated, superheated

to 65 F

Solution:

T2 = [(460 + 65) x 1.33] – 460

= 698 – 460

= 238 F

Although exponents are shown for high compression ratios,

these are for information only. Rating tables define allowable

selection and operation limits.

High Compression Ratio — Avoid compressor oper-

ation at compressor ratios exceeding those covered in the rating

tables. For operating conditions outside the limits shown in

these tables, use 2-stage compression. Care must be taken to

prevent the compressor from pulling down to levels outside the

rating tables.

Suction Gas Superheat — Excessive suction gas super-

heat will result in abnormally high discharge temperatures,

which must be avoided. When using Refrigerants 12, 134a, 502,

and 507/404A it is recommended that the actual suction gas

temperature not exceed the values in Table 4.

Table 4 — Actual Suction Gas Temperature

Limits (F) Refrigerants 12, 134a, 502, and

507/404A*

*With Refrigerant 22, the suction gas superheat should never exceed

25 F for continuous operation.

Keeping Liquid Refrigerant Out of Compres-

sor — Liquid refrigerant, or excessive amounts of entrained

liquid particles in suction gas must be kept out of the compres-

sor by proper system design and compressor control. Under

operating conditions, presence of unevaporated liquid refriger-

ant in the compressor tends to break down oil film on cylinder

walls, resulting in increased wear and loss of machine capacity.

During compressor operation, proper adjustment of the

expansion valve will prevent excessive amounts of liquid from

entering the compressor.

During compressor shutdown, gravity, thermal action and

refrigerant absorption can result in a refrigerant and oil mixture

in compressor crankcase. Gravity flow can be prevented by the

use of recommended loops, but thermal action and the absorp-

tion of refrigerant by lubricating oil cannot be prevented by

piping design.

For the above reasons, the compressor must be controlled

during idle times by one of the following methods.

MINIMUM PROTECTION — The minimum protection that

Carrier will allow is shown in Fig. 1. Actuated control thermo-

stat energizes crankcase heater and closes the liquid line

solenoid valve simultaneously. With crankcase heaters

energized, the crankcase temperature is always held above

shutdown temperature in the evaporator coil and there will be

no refrigerant migration to the crankcase.

With this type of control, a control relay is required and

crankcase heaters have to be energized when the compressor is

not operating.

The control relay coil is located in parallel with the liquid

line solenoid, and a normally open control relay contact is

added in series with the compressor starter and other auxiliary

safety devices.

When the thermostat calls for cooling, the solenoid valve

opens and control relay is energized. This closes the relay

contact and, if other safety devices are in their normal position,

compressor will start. Simultaneously, the normally closed

compressor auxiliary contact will open, removing crankcase

heaters from the circuit.

When the thermostat is satisfied, the solenoid will close and

control relay is deenergized. This opens relay contacts and

compressor stops. This causes compressor auxiliary contacts to

close, energizing crankcase heaters.

Specifications are sometimes written to call for a degree of

protection greater than that afforded by the standard method. If

this is the case, either single pumpout or automatic pumpdown

control may be required.

AUTOMATIC PUMPDOWN CONTROL (Fig. 2) — Pump-

down control is the most effective means of compressor control

in keeping liquid refrigerant out of the crankcase on system

shutdown.

In the basic pumpdown control sequence, the thermostat

controls the liquid line solenoid valve to stop or start the flow

of refrigerant to the evaporator as required.

The pumpdown control system permits compressor cycling

if a system malfunction allows low side pressure to rise.

Although this cycling is sometimes considered objectionable, it

illustrates need for maintenance attention and provides positive

protection against liquid refrigerant accumulating in the

compressor crankcase.

Do not use pumpdown control with dry expansion coolers

as it may cause frost pinching or freeze-up. Do not use

pumpdown control with dry expansion coolers if it is antici-

pated that there will be short bursts of system operation, as this

will result in a gradual loss of oil.

SINGLE PUMPOUT CONTROL (Fig. 3) — Pumpout con-

trol is not as effective as pumpdown control in keeping liquid

refrigerant out of the crankcase. However, it is usually satisfac-

tory when used with crankcase heaters if pumpdown is not

acceptable.

Single pumpout control is similar to pumpdown control,

except that a pumpout relay is added, a normally open com-

pressor auxiliary contact is necessary, and energizing of crank-

case heaters is required at end of each operating cycle.

With single pumpout control, when the thermostat is satis-

fied, the compressor pumps down once and stops. It starts

again only when the thermostat calls for cooling. In pumpdown

control, the compressor cycles only on the low-pressure switch,

regardless of thermostat demands.

Do not use pumpout control with dry expansion coolers as it

may cause frost pinching or freeze-up.

MANUAL PUMPDOWN — The compressor may be con-

trolled manually without the use of pumpdown, or single

pumpout control, and without crankcase heaters, provided the

system is at all times under control of a qualified operator. The

operator will pump down the system by use of manual valves

and will keep liquid, suction and discharge valves closed when

the machine is not operating.

Compressor Capacity Notes

1. Compressor capacities are based on 1750 rpm and 15 F

subcooling for all unit sizes and refrigerants.

2. Multiplying factors for other rpm:

See Multiplying Factors chart on page 31.

3. Liquid subcooling greater than (less than) 15 F incorpo-

rated in ratings increases (decreases) system capacity by

1/2 of 1% for each degree of subcooling. When correcting

for subcooling, brake horsepower does not change.

4. Refrigerant temperatures shown in Table 5 are saturation

temperatures corresponding to pressures indicated at

compressor. Actual gas temperatures are higher because

of superheat.

5. Capacities are based on actual suction gas tempera-

tures to compressor of 65 F for R-12, R-134a, R-502,

and R-507/404A. (This assumes superheat is obtained

from liquid suction interchanger or in evaporator.)

Capacity corrections, other than for rated suction gas

temperatures, may be obtained by using Rating Basis and

Capacity Multipliers Tables 6 and 7. Refrigerant-22

suction gas superheat for ratings (15 F) normally occurs

because of expansion valve operation and line losses.

Therefore, R-22 ratings can be used without adjustment.

An alternate method for capacity correction is to run the

Carlyle Selection program to obtain performance ratings

at other than 65 F return gas temperature.

Compressor ratings and capacities are included in

Tables 8-12.

Compressor Features and Accessories

WATER-COOLED HEADS AND OIL COOLERS — Water

cooled heads are typically not necessary for R-12 or R-134a

applications within the range of compressor ratings shown in

this publication. For R-502, or R-507/404A at the shaded con-

ditions shown in the compressor ratings tables, water-cooled

heads may be necessary, if the discharge temperature is greater

than 275 F. The discharge temperature will increase with return

gas temperature.

When operating conditions are such that suction gas

becomes highly superheated and/or the compression ratio is

high, it is recommended that an oil cooler be used on the com-

pressor. An oil cooler is required on increased displacement

compressors (5H46, 66, 86, and 126) on installations where

compressor(s) can be subjected to extended periods of continu-

ous, fully unloaded operation. These periods do not afford

sufficient removal of compression and friction heat, and could

result in overheating of the running gear, shaft seal and crank-

case oil. The addition of an oil cooler removes excessive

heat, ensuring increased life expectancy of compressor and

components.

Extended periods of continuous, fully unloaded operation

will occur usually on variable-volume installations that use hot

gas bypass to maintain conditions under all load situations.

Without hot gas bypass, the compressor will usually cycle on

the low-pressure switch (or temperature controlling device)

giving time for seal, oil and crankcase to cool.

On multiple-compressor installations where all units are

manifolded into one refrigerant circuit, the controls should be

designed to cycle off compressors at light loads to put maxi-

mum output on the still operative compressor. It is always

desirable for the compressor to operate with as many cylinders

as possible in loaded condition.

Water-cooled oil cooler package is available from the

factory and is easily field installed on all 5 Series compressors.

Refer to 5F,H Compressor Ratings to determine when oil

coolers are required. These ratings, however, do not indicate oil

cooler requirements during periods of extended continuous

operation under fully unloaded operation. This should be

determined on individual job basis.

Water flow through compressor heads (and water-cooled oil

coolers, if used) must be shut off when the compressor is not

running to prevent refrigerant vapors from condensing at the

compressor during OFF cycles. For this purpose a solenoid

valve is recommended in the water supply line to compressor

heads.

Values listed in Table 13 assume a water temperature rise of

30 degrees. Oil cooler and water-cooled heads must be piped in

series, with the oil cooler first. Leaving water temperature

should be between 100 F and 120 F, with 120 F being maxi-

mum allowable temperature. Maximum working pressure for

water-cooled heads is 125 psi.

NOTES:

1. Shaded ratings require an oil cooler when using a liquid-

suction interchanger, or when 50 degrees of superheat is

exceeded.

2. An oil cooler is recommended for all long stroke compressors

(5H46,66,86 and 126).

3. Refer to Table 5 for Total Heat Rejection.

NOTES:

1. Shaded ratings require an oil cooler when using a liquid-

suction interchanger, or when 50 degrees of superheat is

exceeded.

2. An oil cooler is recommended for all long stroke compressors

(5H46,66,86 and 126).

3. Refer to Table 5 for Total Heat Rejection.

Table 13 — Minimum Gpm Required for

Water-Cooled Heads and/or Oil Cooler

(Based on 30° F Rise)

SAFETY RELIEF VALVES — All 5H compressors are

equipped with built-in safety relief valves that are factory set to

relieve from discharge to suction side of the compressor at a

pressure differential of 350 psi.

Safety relief valves that relieve at a 400 psi pressure differ-

ential are factory installed on the 5F60 compressor but are not

available with smaller 5F compressors.

SUCTION STRAINERS — Each 5F,H compressor is

equipped with one or 2 suction strainers located in the suction

manifold. On new installations, felt filters should be used in

suction strainers to trap foreign material left after installation.

After 50 hours of use, these felt filters must be removed. See

5F,H Installation Instructions for further details.

OIL SAFETY SWITCH — An oil safety switch is provided

as standard with all compressors except 5F20 and 5F30. This

switch is optional equipment on 5F20 and 5F30 compressors.

This switch will shut off the compressor before high oil

temperatures or lack of oil causes loss of oil pressure which can

result in compressor failure. As a safety feature, this switch

must be reset manually after cutout.

OIL SEPARATORS — Oil separators in the hot gas discharge

line are not recommended for general use. However, there are

systems where protection afforded by a separator is desirable,

notably systems employing flooded evaporators or refrigera-

tion systems with long system piping. For a more complete

discussion see Carrier’s System Design Manual.

CRANKCASE OIL HEATERS — Crankcase oil heaters are

available for all 5F,H compressors. Heaters keep the crankcase

warm during off cycles and thus minimize refrigerant absorp-

tion in the oil. Crankcase heaters are recommended for CFC or

HCFC refrigerant applications and are required for HFC refrig-

erant applications with POE lubricants. Refer to the 5F,H

Installation Instructions for installation and wiring.

INTERCONNECTION OF COMPRESSORS — All 5F,H

compressors are furnished with removable handhole cover

plates on each crankcase. When field interconnection is desired

on 5F40 through 5H86 compressors, cover plates can be

removed and replaced by special cover plates with tapped open-

ings. These tapped cover plates have connections for both oil

and gas equalizing lines. For interconnection of 5F20 and 5F30

compressors, use the opening for the oil sight glass (see 5F,H

Installation Instructions). Cover plates for interconnection are

standard equipment on 5F120 and 126 compressors.

Many refrigeration systems utilize oil management compo-

nents such as an oil separator, oil reservoir and floats. The oil

level control float an be installed in the sight glass connection

in the 5F,H handhole cover plate.

VIBRATION ISOLATORS — A standard vibration isolation

package is available for each 5F,H compressor. This consists of

a standard rubber-in-shear and compression type mounting that

gives an average static deflection of approximately 1/8 in. and

provides reasonably good vibration isolation at 1750 rpm.

The use of vibration isolators is recommended for all com-

pressor and condensing units because:

1. Transfer of vibration to structure is reduced when the

units are installed on upper floors.

2. They limit drive shaft misalignment on installations

where units are bolted to an uneven concrete floor.

Vibration isolators giving approximately 3/8-in. deflection

are available for superior isolation or if the compressor is run at

slower speeds. Tables 14 and 15 provide an estimated weight

distribution on legs of a compressor or condensing unit when

used with a normal horsepower motor.

MUFFLERS — Four standard mufflers cover the entire model

range of 5F,H compressors. It is recommended that these

mufflers be installed when compressors are used with remotely

located water-cooled or evaporative condensers.

Mufflers are not usually necessary with smaller 5F

compressors and their use is recommended only when quiet

operation is required.

Each piping package to convert 5H compressor units to

condensing units includes a standard muffler of appropriate

size.

Pressure drop through mufflers is about 1/2 psi at 40 F

suction and 105 F discharge with following loadings: 5 tons

with 5F20 muffler, 15 tons with 5F40 muffler, 35 tons with

5H40 muffler and 100 tons with 5H120 muffler.

Capacity Control — For all 5F,H compressors, a

pressure-type cylinder unloader is used. On 5F20 and 5F30

compressors, the capacity control valve is external and on 5F40

through 5H126 compressors the valve is located internally. On

all 5F,H compressors, capacity reduction is in response to

suction pressure.

The cylinder unloading mechanism is powered by a

compressor force-feed lubricating system. This feature assures

unloading of all controlled cylinders at starting regardless of

the position of the capacity control valve, since suction valves

will be held in open position until the lubricating oil pressure

reaches its normal operating level. Refer to Fig. 4 for cylinder

unloading sequence.

An external adjusting stem is provided to set control point

and maintain desired suction pressure. The control point is

adjustable from 0 to 85 psig suction pressure. Differential over

the complete range at any temperature level is 10.7 psig with

Refrigerant 22 and Refrigerant 502. A 7-lb spring (for use on

5F40 and larger units) is furnished with the compressor which,

when used, results in an adjustable control point from 0 to

50 psig with a 6.8 psig range. Insert a spring in the capacity

control valve when R-12 is used. See Fig. 5.

With this arrangement, suction pressure will not drop below

the control set point minus the differential within range of

capacity steps since the compressor will unload to balance its

capacity with evaporator load.

Power elements and valve lifting mechanisms are identical

on all 5F,H compressors. However, when using capacity con-

trol, various methods are used to activate the power elements.

See Table 16 for unloading steps and power requirements at

each step.

5F20 AND 5F30 (Fig. 6)

Major Elements of Control Systems:

1. Capacity Control Valve: Function is to raise or lower oil

pressure from oil pump in response to refrigerant suction

pressure.

2. Power Elements: Function is to supply power necessary

to operate valve lifting mechanism. It is modulated by the

capacity control valve.

3. Valve Lifting Mechanism: Consists of a sleeve and push

pin assembly around each controlled cylinder, designed

to hold the suction valve open, or to permit the valve to

remain in a normal operating position depending on its

actuation by the power element.

Table 16 — Capacity Control Reduction Steps

*Two controlled cylinders (to 331/3%) available on request for 5F30.

Principle of Operation of the System — An increase in suc-

tion gas pressure, which requires increased compressor

capacity, causes the needle valve to close. Therefore, lubrica-

tion oil pressure in power element increases. Increased oil

pressure in power element moves the power piston upward and

the suction valve discs are allowed to seat.

Table 17 indicates control oil pressure at which controlled

cylinders start to and completely unload.

Different points of control pressure on 5F30 are obtained by

using springs with different loading rates in the power element.

Major Elements of Capacity Control Systems:

1. Capacity Control Valve: Function is to raise or lower the

control oil pressure to the hydraulic relay piston in

response to refrigerant suction pressure. Increase in

suction pressure increases control oil pressure in the hy-

draulic relay.

2. Hydraulic Relay: Function is to feed lubrication oil from

the oil pump at full pressure in sequence to one or more

power elements. Relay is activated by control oil pressure

from the capacity control valve.

3. Power Element: Supplies power to operate the valve

lifting mechanism.

4. Valve Lifting Mechanism: Consists of a sleeve and push

pin assembly around each controlled cylinder, designed

to hold the suction valve open, or to permit the valve to

remain in a normal operating position depending on its

actuation by the power element.

Principle of Operation of the System — A decrease in suc-

tion gas pressure, which necessitates a decrease in compressor

capacity, causes the range spring to open the capacity control

modulating valve. This allows control oil to relieve from the

hydraulic relay and thus reduces control oil pressure in the

relay. With reduced control oil pressure, the spring in the

hydraulic relay moves a piston and thus lubrication oil from the

oil pump is prevented from flowing to a particular deactivated

power element. This relieves oil pressure from the power

element allowing the spring in the power element to move the

lifting fork and unload the cylinder. An increase in suction

pressure reverses action and loads cylinders.

5H120, 5H126 CAPACITY CONTROL (Fig. 8) — This ca-

pacity control system is slightly different from the system on

5F40 through 5H86 compressors. Unloaded starting and capac-

ity reduction is obtained by holding open the suction valves of

a number of cylinders. For capacity control purposes, a

suction-pressure-actuated capacity control valve pilots a

hydraulic relay that loads or unloads cylinders in pairs.

Major Difference from the 5F40 through 5H86 Capacity

Control:

1. The hydraulic relay design provides a wider pressure

differential between cylinder cut-in and cutout points.

The relay is a small, easily removed cartridge rather than

an integral part of pump end cover.

2. The surge chamber on 5H120 and 5H126 is an integral

part of the bearing head casting.

PNEUMATIC COMPENSATION OF COMPRESSOR

CAPACITY CONTROL — Adding a control air line to the

external pneumatic control connection permits pneumatic

resetting of the control point in accordance with changes in

operating conditions. Each pound of change in air pressure

resets the control one pound in the same direction. Thus, a one-

pound rise in air pressure will cause unloading to begin at a

suction pressure one pound higher than the original control

point, etc. Figure 9 shows a typical pneumatic control arrange-

ment. All components and installation instructions are field

supplied.

Control Pressurestats — Dual pressurestats are furnished with

all 5F,H compressors. They are often referred to as high- and

low-pressure cutouts. Their function is to cut the circuit to the

holding coil of the compressor motor starter when pressure

setting limits are exceeded.

The high pressurestat has an operating range from 50 to

450 psig with a differential range from 170 to 235 psig (adj).

The low pressurestat has an operating range from 20 in. Hg to

60 psig and a differential range from 60 to 90 psig (adj).

Pressurestat settings should be adjusted on the job to meet

particular operating conditions for which the compressor(s)

have been selected. Directions for setting these pressurestats

are in the 5F,H Installation Instructions.

Permanently Unloaded Cylinders — Operation of an open-

drive compressor with its cylinders permanently unloaded

requires field modification. The 5F60, 5H40 and 5H60 com-

pressors can operate with one cylinder unloaded; 5H80 and

5H120 compressors can operate with 2 cylinders unloaded.

Compressors are modified by removing the suction valve and

suction valve springs from the cylinder(s) shown in Fig. 4.

ELECTRIC SOLENOID VALVE CAPACITY CON-

TROL — Closer control of a conditioned space or medium

can be realized by activating the cylinder unloaders directly in

response to an external step controller activated by solenoid

valves. A temperature sensing controller activates the electric

solenoid valves. Refer to Fig. 10 for an operating concept using

an external electric solenoid-type capacity control. All compo-

nents external to the compressor must be field supplied. Modi-

fications required for standard sequence are as follows:

5F20 and 5F30 Compressors — Modifications are not

required to the 5F20 and 5F30 compressors. See Fig. 4 and 11.

Securely attach a ported solenoid valve to compressor to mini-

mize line vibration. Connect a 1/4-in. steel tubing or high-

pressure flexible hose, KA73RR025, between the compressor

and solenoid valve.

5F40 and 5F60 Compressors

1. Remove the capacity control handhole cover. Remove the

hydraulic relay and all tubing. As shown on Fig. 12, drill

and tap 3 holes on the bottom side of the cover and 2 on

the front. No hole is required at point A on 5F40 com-

pressors. Plug 5 cover holes that connected cover to the

relay. Plugs are 1/8 NPT.

2. Install cover with a new cover gasket 5F40-1042.

3. Mount solenoid valves on a sturdy bracket attached to the

handhole cover using stud bolts on the compressor.

4. Connect external oil lines as shown in Fig. 12 and 13.

Steel tubing and compression fittings are recommended.

5H40 Through 5H86 Compressors — Standard compressors

5H40 through 5H86 built after Serial No. G103460 (July 1971)

may be modified for electric solenoid unloading without addi-

tional machining. Proceed as follows: (See Fig. 4, 13, 14,

and 15).

1. Remove pump end cover only from the compressor.

2. Using the pump end cover gasket (Part No. 5H40-1423)

as a guide, make a blank metal disc (1/32 to 1/16-in. thick),

making holes for bolts only.

3. Reinstall the pump end cover using 2 new 5H40-1423

gaskets, one on each side of the blank disc. This isolates

the capacity control cover.

4. Mount solenoid valves and run oil lines.

5. To minimize vibration, mount the valves on a bracket

attached to the compressor.

5H120, 126 Compressors — Following modifications are

required to electrically unload 5H120, 126 compressors.

1. After closing the compressor service valves and reducing

refrigerant pressure to the atmosphere, remove pump end

bearing head.

2. Remove hydraulic relay assembly by removal of two

5/16-in.-18 socket head screws. Make a blank metal disc

using a hydraulic relay gasket (5H120-3351) as a guide.

Using 1/32 to 1/16-in. thick metal, cut holes in the disc for

dowel pins only. (Do not cut five 9/32-in. diameter holes.)

Reinstall relay assembly using 2 new 5H120-3351

gaskets, one on each side of the metal disc. Torque

5/16-in. socket head screws evenly to 16 to 20 lb-ft.

3. Reinstall the bearing head using extreme care not to

damage the oil pump tang. Align with recess in the end of

the crankshaft. Do not force on.

4. Mount solenoid valves and run oil lines. See Fig. 4, 13,

and 16.

5. To minimize vibration, mount the valves on a bracket

attached to the compressor.

CAPACITY CONTROL MODIFICATIONS FOR HEAT

PUMP APPLICATION — Where 5F40, 5F60, and 5H com-

pressors are used in refrigerant cycle reversing heat pump

applications, it is usually necessary to modify the standard

capacity control arrangement to satisfy unloading require-

ments. On summer cycle, the compressor is required to unload

as circulating water or air temperature drops. During winter

cycle, the control works in reverse, so that the compressor

unloads as the circulating water or air temperature increases. It

is necessary for the compressor to unload in response to either

a summer or winter temperature-sensing device, depending on

the particular cycle in operation.

Where summer and winter design suction temperatures are

within design range of either electric or pneumatic compensa-

tion devices, capacity control may be external. However,

another means is normally required.

Usually modification to the compressor capacity control

system is required. The compressor can be modified in 2 ways:

(1) for applications requiring 50% capacity reduction; (2) for

applications requiring more than one step of capacity reduc-

tion. See Fig. 10 for a typical 2-step external capacity control

arrangement.

Application Requiring 50% Capacity Reductions — This is

the usual specification for heat pump applications and should

cover majority of cases. The necessary modifications to com-

pressor capacity control can be accomplished by ordering the

compressor with factory modifications and then completing

modification at the jobsite with field-supplied components.

Factory Modifications — The compressor order should state

that compressor is to be special for heat pump application, and

is to include only enough unloader power elements to unload

the compressor down to 50% displacement. The unloaded

cylinders will be those closest to pump end of the compressor.

Field Completion — Install a 1/4-in. or 3/8-in. bypass line

between the control oil pressure connection and the crankcase

and install a solenoid valve in this line.

The cylinders set up for unloading may be loaded or unload-

ed by operation of this solenoid valve. When the solenoid valve

is closed, full oil pressure is available to the controlled

cylinders and these will be loaded so that compressor will be

operating on 100% capacity. When the solenoid valve is open,

oil pressure will be bled from the controlled cylinders and they

will be unloaded, so that compressor will then be operating at

50% capacity. A 2-step thermostat controlling the compressor

can thus utilize 2 capacity steps by operating the compressor

starter and solenoid bypass valve.

Application Requiring More Than One Step of Capacity

Reduction — This can be furnished on special order for com-

pressors having 6, 8, or 12 cylinders. Arrangement consists of

furnishing a compressor with external solenoid unloading type

capacity control. The control can be furnished with or without

3-way valves (Table 18).

Table 18 — Capacity Control Steps and

Heat Pump Modification

Hot Gas Bypass — Hot gas bypass may be required on

some systems for one of the following reasons:

1. Frequent operation at loads below minimum capacity

(compressor fully unloaded).

2. To avoid low-load compressor cycling on the low-

pressure switch. Excessive cycling can reduce equipment

life and increase demand charges.

3. Specifications call for hot gas bypass (better humidity

control, etc.).

The variety of systems using 5F,H compressors make it

impractical to cover all aspects of hot gas bypass operation.

The following guidelines will aid in determining the proper

application.

The hot gas bypass valve is basically a pressure regulating

valve installed to hold a constant compressor suction pressure.

It should operate over as small a pressure range as possible.

The normal set point of the valve should be coordinated with

cylinder unloaders so that the bypass valve starts to open at a

pressure where the last cylinder bank unloads, and is fully open

at a slightly lower pressure. Types, ratings and published appli-

cation guides for various available valves must be evaluated to

determine the proper valve and installation practice for each

application.

If a compressor system is to operate down to zero load, the

valve capacity should equal compressor capacity when fully

unloaded. For systems using multiple evaporators, it may be

necessary to use multiple hot gas valves.

Hot gas should be taken from a point as close as possible to

compressor discharge and fed through a hot gas solenoid valve

and then through a hot gas valve. The hot gas solenoid valve

can be controlled by a pressure switch or temperature switch.

On compressors equipped with an electrically actuated cylinder

unloader, the hot gas solenoid should be wired in parallel with

the solenoid that unloads the final cylinder bank so that bypass-

ing starts immediately when all cylinders are unloaded.

HOT GAS INJECTION INTO LIQUID LINE — When

amount of bypass is small and the evaporator has a low pres-

sure drop distribution system and existing system piping does

not present problems, hot gas is frequently injected into the

liquid line between the thermostatic expansion valve (TXV)

and the evaporator. The ideal point for hot gas injection is into

the side inlet of a side connection distributor, where inlet is

downstream of distributor orifice. If too much hot gas is

injected upstream of a distributor orifice, gas binding and

erratic expansion valve operation will result. Injection into

liquid line is recommended whenever practical, since agitation

in the evaporator and normal operation of the TXV will tend to

thoroughly desuperheat injected hot gas and prevent compres-

sor overheating.

HOT GAS INJECTION INTO COMPRESSOR SUCTION —

Hot gas injection into compressor suction is sometimes neces-

sary but must be done with caution to ensure sufficient

desuperheating of hot gas and to prevent liquid slugging in the

compressor. Following guidelines should be observed:

1. Inject hot gas as close as possible to the evaporator outlet.

2. Install a TXV bulb at least 3 or 4 ft (further if possible)

downstream from the hot gas injection point to ensure

good gas mixing before the bulb.

3. Install a separate small TXV to inject liquid refrigerant

into the suction line along with bypass gas. This valve

should have capacity approximately 25% of hot gas

valve capacity since hot gas must be superheated but not

condensed.

4. Install a suction (knockout) drum in the suction line

immediately before the compressor and downstream of

the hot gas inlet and liquid injection inlet. Only larger

industrial systems or systems with many remote evapora-

tors can normally justify the extra expense of injecting

hot gas into the compressor suction.

Motor Selection Data — Motor selection data based on

brake horsepower occurring at design operating condition is

usually satisfactory for applications in air conditioning suction

temperature range.

Required compressor starting torque is dependent on dis-

charge pressure as well as pressure differential occurring

during start-up and is the same for any compressor speed.

Values shown in Table 19 indicate maximum starting torque

for R-12, R-134a, R-22, R-502, and R-507/404A. In most

cases, a standard torque motor can be selected because of

the partially unloaded starting feature of the 5F and 5H

compressors.

In selection of a motor, the required motor starting torque

must exceed the compressor starting torque only when the

compressor is operating at same speed as the motor. If com-

pressor speed is less than motor speed, as on some belt drive

units, the motor starting torque requirements are reduced in

proportion to the speed ratio between the compressor and

motor because of mechanical advantage available to the motor.

In special applications or systems where there is a large

pulldown requirement, the bhp requirement during pulldown

may significantly exceed bhp at design conditions. The motor

must not be overloaded during pulldown operation. If the

motor is sized for pulldown, it will be only partially loaded

during design operation and will run inefficiently. Therefore,

select a motor that will be optimized for system design require-

ments and not for pulldown requirements. Two ways for

handling this are:

1. Install a crankcase pressure regulator in the system to

maintain a given saturated suction temperature, thereby

controlling bhp requirement, or

2. Install a current sensing device so that the motor current

draw does not exceed the maximum rated motor current.

BOOSTER COMPRESSORS FOR

REFRIGERANT 12, 22, 502, AND 507/404A

Booster Application Data — The following data sup-

plements the single-stage compressor application data, and

adds information pertaining to booster application only. Refer

to the single-stage compressor data for all other information.

Rating Basis — All booster ratings* are given in refriger-

ation effect and are based on:

1. Use of a liquid-suction heat interchanger. All liquid-

suction interchangers should have a bypass connection on

the liquid side so that adjustment can be made in event

that too much superheating of suction gas causes exces-

sive heating of compressor. This is especially true for

Refrigerant 22, which has a higher compression exponent

than Refrigerant 12.

2. The liquid refrigerant at Point A (Fig. 18) at satu-

ration temperature corresponds to booster discharge

pressure. This is often referred to as saturated inter-

mediate temperature.

This occurs when booster discharge gas is condensed in a

cascade (refrigerant-cooled) condenser, or when using an

open flash-type intercooler in a direct staged system.

When subcooling of liquid takes place in a closed-

type intercooler, it is not possible to bring liquid tempera-

ture down to saturated intermediate temperature because

of temperature difference required for heat transfer

through the liquid coil. In this case, the compressor rating

must be decreased 3% for each 10 degrees that liquid

temperature at Point A is above the saturated intermediate

temperature.

3. Use of only half of the standard number of suction valve

springs per cylinder. All 5F,H compressors are factory

assembled with the standard number of suction valve

springs; therefore, one-half of the springs per cylinder

must be removed in the field for booster applications.

4. Booster ratings are based on a 1750 rpm compressor

speed.

*R-507/404A ratings are similar to R-502.

“R” Factors — In a multistage compression system, the

intermediate or high-stage compressor must have sufficient

capacity to handle the low-stage (booster) compressor load

plus heat added to refrigerant gas by a low-stage machine

during compression. Likewise, if an intermediate stage com-

pressor should be used, the high-stage compressor must have

sufficient capacity to handle the intermediate stage compressor

load plus heat added to the refrigerant gas by an intermediate

stage machine during compression.

To assist in the selection of higher stage compressors,

Table 23 presents “R” factors that depict approximate required

relationship between stages at various saturated temperature

conditions.

To determine the required capacity of a higher stage com-

pressor, multiply lower stage compressor capacity by the

proper “R” factor from Table 23. Any additional loads handled

at intermediate pressure must be added to this figure to arrive at

the total higher stage load.

Multistage System Pointers — A staged system is

essentially a combination of 2 or more simple refrigerant

cycles. In combining 2 or more simple flow cycles to form a

staged system for low temperature refrigeration, 2 basic types

of combinations are common (Fig. 18).

DIRECT STAGING — Involves use of compressors, in

series, compressing a single refrigerant.

CASCADE STAGING — Usually employs 2 or more refrig-

erants of progressively lower boiling points. Compressed

refrigerant of low stage is condensed in an exchanger (cascade

condenser) that is cooled by evaporation of another lower

pressured refrigerant in the next higher stage.

Safety Factors — Use of capacity safety factors in select-

ing booster compressors must be a matter of judgment when

making selection.

Factors that have a bearing on satisfactory compressor

selections are: accuracy of load estimate, amount of safety

factor included in the total load, degree of importance of meet-

ing specified capacity at given condition, temperature level of

operation and magnitude of refrigeration load. All of the

factors must be recognized when considering the use of a

capacity safety factor in selecting a booster compressor.

Figure 19 presents reasonable safety factors for use in selec-

tion of booster compressors. These can be employed when it is

not desired to establish a factor based on selector’s judgment.

When a capacity safety factor is used, the compressor is

selected at its maximum speed to handle design load plus safe-

ty factor. Multiplying factors for non-standard speeds are

shown in Fig. 20.

Whether or not added capacity offered by the safety factor is

incorporated at once is a matter of judgment. If it is, then the

compressor will be operated at maximum speed at the start and

any excess capacity achieved will be reflected in faster

pulldowns or lower temperatures. It is also a good practice to

drive the machine at a speed that will provide slightly more

rated capacity than is required by design load. Additional

speed-up available will then constitute reserve capacity in the

event it is needed. Motors should be sized to run the compres-

sor at maximum speed to forestall any motor changes, should

this maximum compressor speed be required in the future.

Determining Intermediate Pressure — In applica-

tion of commercial compressors to staged systems, the lowest

total bhp per ton and most economical equipment selection

results when using approximately equal compression ratios for

each stage. It is also economical to juggle assigned compres-

sion ratios to fit available sizes of machines.

The use of Fig. 21 (page 32), will allow direct determination

of proper intermediate pressure that will result in equal com-

pression ratios per stage for a direct 2-stage system. Informa-

tion in Fig. 21 is given in terms of saturated temperature

instead of pressures, for easier use with compressor ratings.

Existence of a second appreciable load, at some higher

suction pressure level, will often dictate the most convenient

intermediate pressure.

Gas Desuperheating — Operation of a direct staged

system requires cooling of the gas between stages; otherwise,

highly superheated discharge gas from low-stage machine

would be taken directly into the suction of higher stage com-

pressor and further compression would result in excessive

heating of this compressor.

Liquid Cooling — It is also necessary to employ liquid

cooling between stages and increase refrigeration effect of

liquid delivered to evaporator to realize rated capacity of boost-

er compressor. Amount of refrigeration expended in cooling

liquid between stages is accomplished more economically at

the level of high-stage compressor suction than at the level of

low-stage suction.

Three common methods of gas desuperheating and liquid

cooling for direct stage systems are illustrated in Fig. 18. In

open-type systems, refrigerant liquid is cooled down to the

saturation temperature corresponding to intermediate pressure.

In closed-type systems, good intercooler design usually results

in refrigerant liquid being cooled down to 10 to 20 degrees

above saturation temperature corresponding to intermediate

pressure.

Oil Separators and Lubrication — In cascade-type

systems, where evaporators and suction lines are properly

designed for oil return to the compressor, oil separators are

usually not used.

In direct stage systems, however, oil may tend to accumu-

late in one of the stages and thus result in lack of lubrication in

other machine. By use of oil transfer lines, equalization of oil

level between crankcases can be achieved by manual operation

at periodic intervals. Automatic control of proper oil return to

both compressors is effected by use of a high stage discharge

line oil separator, returning oil to high stage machine, and a

high side float, connected to high stage machine crankcase,

which continually drains excess oil from this crankcase down

to the next lower stage compressor (Fig. 18).

For booster application, factory oil charge should be drained

and replaced with a suitable viscosity oil for low temperature

application.

Discharge Valve Springs — When 5H compressors

are used for booster applications where discharge pressure is

below 10 psig, the standard discharge valve springs furnished

with the machine should be replaced with an equal number of

lighter weight springs, Part Number 5H41-1801.

No change in discharge valve springs is recommended for

5F compressors.

Water-Cooled Heads — Standard 5F,H compressors

are not equipped with water-cooled heads but they are avail-

able on special order. Water cooling of heads is generally not

necessary in R-12 or R-502 booster applications. For applica-

tions with R-22 involving high compression ratios, 5 or above,

5F,H booster compressors should be equipped with water-

cooled heads.

Motor Selection Data — In staged refrigeration sys-

tems, the high stage compressor starts first and runs until low

stage pressure has been reduced to a predetermined level

before the low stage machine starts. With direct staged arrange-

ments, the high stage machine draws gas from the evaporator

through low stage machine bypass during this initial period.

Size of the selected motor must be related to the maximum

condition at which booster compressor can operate.

Compressor may run under heavy loads during periods of

high suction pressure, especially on starting when system is

warm. To handle these situations the motor must be sized larger

than the actual balanced operation brake horsepower indicates,

or special attention must be paid to operation of the system

when starting initially. Tables 25-27 give balanced brake horse-

power values at 1750 rpm.

If the system is to operate only at a fixed low temperature, it

is possible to avoid oversizing of motors providing careful op-

eration is followed when the system is first put in operation.

On applications requiring reduction from ambient condi-

tions to some extremely low temperature, the compression

system will be operated at high suction pressures for consider-

able periods of time. General practice is to drive the high stage

compressor with a motor that will operate compressor at the

highest expected evaporator temperature. This is generally the

“air conditioning” rating of unit. For intermediate or low stage

compressors, it is generally sufficient to size motor to take care

of double the balance load indicated horsepower plus friction

horsepower.

Also consider compressor starting torque requirements

when selecting motor for a booster compressor. Starting torque

of a motor only large enough to provide required normal

operating bhp for booster applications may not be large enough

to start the compressor. Recommended minimum motor sizes

shown in Table 28 have been selected to assure adequate

starting torque. Actual motor size selected is usually larger,

depending on the maximum bhp conditions under which the

compressor will run during pulldown or other abnormal operat-

ing periods.

It is good practice to select motors with allowance for 10%

voltage reduction unless there is a certainty that this cannot

occur.

Compressor Starting Torque — Required compres-

sor starting torque is dependent on the discharge pressure as

well as the pressure differential occuring during start-up.

Maximum expected torque required during the starting period

for 5F,H compressors, used as boosters, is shown in Table 28 at

2 saturated discharge temperatures.

Selection Procedure — Selection of a 5F,H booster

compressor requires that the load, saturated suction tempera-

ture, saturated discharge temperature, type of system and

refrigerant are known.

After the saturated intermediate temperature is determined

from Fig. 21, the booster rating (Tables 25-27) can be entered

and the compressor selected. Low stage load is then multiplied

by the “R” factor from Table 23 to obtain high stage compres-

sor load. With this information, the Compressor Ratings tables

on pages 7-15, and page 17 can be entered and the high-stage

compressor selected.

Find: Compressor size and motor size.

Solution:

1. Figure 21 indicates an optimum saturated intermediate

temperature of –2 F. Allow a 1 degree or 2 degree drop

from the booster compressor to intercooler and from the

intercooler to the high stage compressor.

Booster Saturated Suction Temperature = –60 F

Booster Saturated Discharge Temperature = 0° F

2. At –60 F suction and 0° F discharge, the 5H60 booster

compressor has a capacity of 6.8 tons with 12.1 bhp input

at 1750 rpm.

The safety factor at 1750 rpm:

This is satisfactory from Fig. 19 and a 5H60 compressor

is selected.

3. Indicated hp (ihp) = bhp – Friction hp (fhp)

Where bhp is given in Table 26 and fhp is given in

Table 28.

Indicated hp (ihp) = 12.1 – 3.07 = 9.03

Recommended minimum hp

= (2 x ihp) + fhp

= (2 x 9.03) + 3.07 = 21.13

Tentatively select a 25-hp motor. Assume that low stage

will never start against a saturated discharge higher than

30 F. At 30 F discharge, Table 28 indicates a starting

torque of 54 lb-ft. Therefore, a normal starting torque

25-hp motor is selected.

4. With –60 F suction and 0° F discharge, Table 23 indicates

an “R” value of 1.303. Therefore, the high stage load is:

1.303 x 6.8 = 8.86 tons (actual load)

5. Allowing a 1 degree drop from the intercooler, the high

stage saturation suction temperature is –3 F.

Allowing a 2 degree drop between the compressor and

condenser, the high stage saturated discharge temperature

= 80 + 2 = 82 F.

6. Referring to the 5F,H Compressor Ratings table, 5F60 at

1450 rpm (using multiplier in compressor capacity notes)

has a capacity of 9.21 tons at –3 F suction and 82 F dis-

charge (through interpolation). The 5F60 is selected and

requires 13.0 bhp at 1450 rpm.

7. Assume that maximum load during pulldown occurs at

50 F suction and 90 F discharge. For this condition, the

rating tables (using the multiplier in Step 6) indicate

15.8 bhp, thus a 20-hp motor is selected.

(6.8 )x 100 – 100 = 19.3 or 20%

CONDENSERS

Condenser Physical Data — Refer to Table 29. Re-

fer to 5F,H Product Data for information on the current

P701 water-cooled condensers used with the 5F,H water-

cooled condensing units.

Condenser Selection Considerations — On most

installations the condenser is selected within recommended

conditions specified in ARI Standards. Main consider-

ations are:

1. The water velocity is within a range of 1 to 12 ft per

second (to minimize corrosion and erosion).

2. It is good practice to select condensers on a leaving tem-

perature difference between 6 and 12 degrees. In general,

higher temperature differences are used only where con-

densing water temperature is quite low or where special

conditions make it economical to do so. A high tempera-

ture difference not only makes effect of fouling more

pronounced but since the condenser volume is likely to be

small, the effect on noncondensable gases will be greater.

Table 30 lists maximum water velocities from Carrier

System Design Manual. Limits are above ARI recommended

values but are generally accepted where ARI conformance is

not specified. See Part 5 of the Carrier System Design Manual

for further details.

Table 31 lists condenser water quantities (gpm) for water

velocities from 3 to 12 fps. For higher velocities, use formulas

below Table 31.

Condenser Duty — The capacity of a given compressor

is greatest at high saturated suction temperatures. Because of

this, the compressor normally requires the largest condenser at

these conditions or for air conditioning duty.

On refrigeration or low temperature applications, the same

compressor displacement results in a lower refrigeration

capacity and, consequently, less heat rejection. Thus, con-

denser size is smaller than would normally be required with the

same compressor on air conditioning duty.

Condenser size is also affected by refrigerant used, since

compressor capacities (and thus heat rejection) differ with

Refrigerants 12, 22, and 502.

Pulldown — Condensers for systems subject to pulldown

periods, especially low temperature or multistage systems,

should be oversized beyond the capacity required at the final

balanced load condition. The condenser must adequately

handle load during the first stages of pulldown, when system

capacity is substantially greater than at final condition.

If pulldown load is sizable, as in most water or brine cooling

applications, check the condenser performance when it is

handling total heat rejection at maximum rated suction temper-

ature (50 F for most compressors). Condenser size and water

quantity must be adequate to handle this start-up load without

resulting in excessive head pressure or excessive water pres-

sure drop. As a rough guide, the selected condenser should

have a maximum total heat rejection rating that is equal to

or greater than the compressor heat rejection at pulldown

conditions.

If this pulldown occurs infrequently, it may be possible to

select a condenser for design conditions and on each start-up

limit compressor capacity by manually throttling suction gas

flow. This can be done by partially closing suction valve but

this will extend time required to reach design conditions.

If the pulldown is of short duration, such as on a direct

expansion coil, suction temperature will drop very rapidly and

more than likely design conditions will be reached before the

compressor would cut out on high pressure. No oversizing of

the condenser would be required.

Whenever possible, the selected condenser should never be

of a larger size than the largest condenser that will match the

compressor used and still be a standard combination. This

should be considered especially when the condensers are to be

used with 5F,H series open reciprocating compressors.

Fouling and Fouling Factors — Fouling in con-

denser tubes is result of a build-up of scale within tubes

because of impurities in water. As a result, heat transfer is

adversely affected. Fouling factors are a means of identifying

degree of fouling.

Condensers should not be selected for less than 0.0005 foul-

ing factor, even when high quality water is available. For lower

quality water, use larger fouling factors from the condenser

ratings, but temper factor according to operating conditions.

The following affect magnitude of fouling factor selected:

• Percentage of yearly operating time.

• Frequency of tube cleaning.

• Condensing temperature.

• Type of water treatment.

For instance, reduce fouling factor when the operating time

is less than 4000 hours per year, when frequent cleaning of

tubes takes place, or when low condensing temperatures exist.

Water Circuiting Arrangements — The water cir-

cuiting arrangement selected for 5F and 09RH condensers

depends on available condenser water pressure, temperature,

quantity and source. Refer to Table 32.

Refer to the Carrier System Design Manual for specific

information and recommendations for refrigerant and water

piping.

Economics — Selection of a condenser requires balancing

of certain economic variables, including:

1. First cost of compressor-condenser combination.

2. Operating costs.

3. Ratio between power costs and water costs.

Where first cost is the most important consideration, the

best combination of compressor and condensers has the lowest

total equipment cost.

If owning and operating costs are important, combination

must be selected on basis of both considerations.

A condenser selection that permits operation of the system

at a low condensing temperature, results in the lowest compres-

sor motor brake horsepower and consequently, lowest operat-

ing cost. A condenser selection that is heavily loaded requires

the compressor to operate at a higher condensing temperature

and results in higher compressor motor brake horsepower and

operating cost.

For a given compressor-condenser combination, selection

of a condensing temperature may depend on a ratio between

power costs and water costs, on quantity of water available,

on condensing temperature required to achieve compressor

capacity, or a requirement to remain within allowable loading

on a given motor size.

Condenser Performance with Ethylene Gly-

col — Increased use of closed circuit cooling towers has led

to a corresponding increase in the need for shell and tube con-

denser ratings for use with ethylene glycol. When towers are

installed outdoors, a brine solution is required for freeze protec-

tion during winter operations.

In most outdoor installations, specifications will call for a

percentage of concentration of ethylene glycol or other brine

solution. If concentration is not specified, it may be the choice

of the contractor to determine a percentage of glycol concentra-

tion to ensure against freeze-up during winter minimum design

ambients.

To perform simplified selection, use Fig. 22 to convert a

condenser water rating to a brine rating.

EXAMPLE:

Assume that a building with a year-round cooling load has a

cooling requirement of 120 tons during summer design condi-

tions. Chilled water design temperatures are 54 F entering to

44 F leaving, and for summer duty, the condenser water is

based on 85 F and a 10 degree rise.

From product literature, selected unit will deliver 121 tons

at 105.8 F saturated discharge temperature (SDT) and has

153 tons of heat rejection.

Determine condenser loading factor by use of following

formula:

Where: EWT — Entering Water Temperature

LF — Loading Factor

THR — Total Heat Rejection

The 85 F value is return water temperature from closed cir-

cuit cooler.

Entering condenser rating data at loading factor of 7.9,

300 gpm are required to maintain design condensing tempera-

ture. Next, determine the rise by:

If a more precise rise is desired, go back and assume a

slightly different condensing temperature, recalculate the load-

ing factor and rise and repeat the procedure until a final balance

is found.

For this example, condenser water pressure drop is approxi-

mately 9.4 ft for the design 300 gpm flow rate. Using Fig. 22,

flow rate correction can be determined for any glycol concen-

tration versus water in shell and tube condensers.

Continuing with example, assume specifications required

protection against freeze-up at an ambient of 0° F. (A glycol

concentration that provides protection between 10 and 15 de-

grees below expected minimum ambient has been the design

criteria for many years.)

In a condenser system, the use of proper ethylene glycol

brine concentration is important because of the phenomenon

that commonly published freeze points are not freeze points but

are the point of crystallization where the first crystals begin to

form. Actual freezing into a solid occurs at much lower

temperatures. For example, freeze point of 20% ethylene

glycol is given as +16 F but does not become a solid until it

reaches –50 F; 35% ethylene glycol with a freeze point of –6 F

does not become solid until it reaches –120 F. Consequently,

20% glycol solution will take care of most domestic applica-

tions and 35% brine should satisfy the rest. The lowest con-

centration of brine will be the most efficient and result in

considerable energy conservation.

Entering Fig. 22 at 0° F crystallization point, necessary

concentration of glycol is either 32.5% by weight or 30% by

volume. Next, determine glycol flow rate:

Determine glycol factor (GF) by entering Fig. 22 at proper

glycol concentration and reading left from glycol factor line —

in this case a glycol gpm factor of 33.5.

Therefore, at 32.5% by weight ethylene glycol specified and

used to satisfy design conditions, a flow rate of 513 gpm of

brine solution would be required and this value used to select a

closed circuit cooler. Closed circuit cooler selection can be

made from the manufacturer’s literature or by contacting the

local representative.

With the increase in brine flow rate, the rise will now be:

Next determine the glycol pressure drop.

Equiv Water Flow = Glycol Flow x Press. Drop Factor

Pressure drop factor can be determined by entering Fig. 22

at the proper concentration of glycol solution (30% by vol-

ume), going to the pressure drop factor line and reading right to

the pressure drop factor. For this example the factor is 1.1.

Equiv Water Flow = 513 x 1.1

= 564 Gpm

Entering condenser water pressure drop curve in product

literature at 564 gpm, the brine pressure drop can be deter-

mined. Note there will be an increase in flow rate and pressure

drop with ethylene glycol as compared to a straight water cool-

ing system.

In conclusion, add a glycol solution to a condenser system

only when conditions warrant. Do not add more than is

required. When glycol is used, proper control of inhibitor

concentration is necessary to maintain design properties of

solution and prevent corrosion.
