The 38AH condensing unit offers the

utmost in system conﬁguration and

control adaptability. Its premium-

quality standard components ensure

durable, efﬁcient and reliable

operation.

Versatility

38AH Series condensing units feature

up to 4 compressors and 2 refriger-

ant circuits, and can be matched with

a wide variety of air-handling units.

All condensing unit circuits can supply

a single air handler; size 044-134

units can supply 2 separate air

handlers.

Standard units have constant vol-

ume control. A variable air volume

(VAV) option is available. The VAV

units have electric unloaders on the

compressors to closely match building

loads. The VAV option requires only

a simple connection to the Carrier

ModuPanel™ discharge air controller,

thereby saving installation time and

cost. (NOTE: Unit sizes 024-034

require ﬁeld supplied and installed

accumulator.)

Durable construction

All 38AH units have weatherized cabi-

nets constructed of heavy-duty galva-

nized steel prepainted with corrosion-

resistant baked enamel. Inside and

outside surfaces are protected to en-

sure long life and good looks. The

durable, galvanized steel, prepainted

components exceed the requirements

of the 500-hour salt spray test per

ASTM B117.

The unit’s coils have aluminum ﬁns

mechanically bonded to copper tubes

for long-term reliability and improved

heat transfer. An inert epoxy bar-

rier is available on precoated ﬁns to

provide improved durability in mildly

corrosive coastal environments. Cop-

per ﬁns on copper tubes are avail-

able for harsh industrial or coastal

conditions.

Reliability

The 38AH condensing units feature

time-proven, highly reliable 06D and

06E semi-hermetic compressors.

Unloading capability is a standard fea-

ture on the lead compressor of each

circuit. Each compressor has vibration

isolators to provide quiet operation

and reduced component stress.

Because 38AH units have 2 inde-

pendent circuits, they provide inherent

backup capability. Each circuit is also

protected by the following safety

features:

• Time Guardtanti-short-cycling

device

• low oil pressure safety switch

• low refrigerant pressure switch

(suction)

• high refrigerant pressure switch

(discharge)

• calibrated circuit breakers for com-

pressors and outdoor fans

Easier installation and service

38AH units are equipped with hinged

control-box access doors, liquid line

shutoff valves, and service valves

on the compressors.

Larger 38AH124 and 134 size

units are shipped as 2 modules for

easier handling and rigging.

Feature/Beneﬁts (cont)

Innovative Carrier 40RM air-

handling units in sizes 016-

034: ideal matches for

38AH024-034 condensing

units

The 40RM Series has excellent fan

performance, efﬁcient direct-expansion

(DX) coils, a unique combination of

indoor air quality features, and easy

installation. Its versatility and state-of-

the-art features help to ensure that

your split system provides economical

performance now and in the future.

Indoor-air quality (IAQ)

features

The unique combination of IAQ

features in the 40RM Series air

handlers helps to make sure that only

clean, fresh, conditioned air is deliv-

ered to the occupied space.

Direct-expansion (DX) cooling coils

prevent the build-up of humidity in the

room, even during part-load condi-

tions. The 016-034 sizes feature dual-

circuit coils.

Standard 51-mm (2-in.) disposable

ﬁlters remove dust and airborne

particles from the occupied space.

Thermal insulation contains an

immobilized anti-microbial agent to

inhibit the growth of bacteria and

fungi. The anti-microbial agent is reg-

istered with the U.S. Environmental

Protection Agency (EPA).

The pitched PVC drain pan can be

adjusted for a right- or left-hand con-

nection to provide positive drainage

and to prevent standing condensate.

The 40RM accessory economizer

can provide ventilation air to improve

indoor-air quality. When used with

CO2sensors, the economizer admits

fresh outdoor air to replace stale,

recirculated indoor air. Includes 24-v

controls.

Economy

The 40RM Series packaged air

handlers save money by providing

reduced installation expense and

energy-efﬁcient performance.

Quick installation is ensured by the

multiposition design. Units can be

installed in either the horizontal or

vertical (upﬂow) conﬁguration without

modiﬁcations. All units have drain-

pan connections on both sides, and

pans can be pitched for right- or left-

hand operation with a simple ad-

justment. Fan motors and contactors

are prewired and thermostatic ex-

pansion valves (TXVs) are factory-

installed on all 40RM models.

High efﬁciency, precision-balanced

fans minimize air turbulence, surg-

ing, and unbalanced operation, cutting

operating expenses.

The economizer accessory precisely

controls the blend of outdoor air and

room air to achieve comfort levels.

When the outside air enthalpy is suit-

able, outside air dampers can fully

open to provide ‘‘free’’ cooling.

Rugged dependability

40RM units are made to last. The

die-formed galvanized steel panels

ensure structural integrity under all

operating conditions. Galvanized steel

fan housings are securely mounted

to a die-formed galvanized steel deck.

Mechanically bonded coil ﬁns pro-

vide improved heat transfer. Rugged

pillow-block bearings are securely fas-

tened to the solid steel fan shaft

with split collets and clamp locking

devices.

Coil ﬂexibility

Model 40RM direct-expansion coils

have galvanized steel tube sheets; inlet

and outlet connections are on the

same end. The coils are designed for

use with Refrigerant 22 and have cop-

per tubes mechanically bonded to

aluminum sine-wave ﬁns. The coils

include matched, factory-installed

TXVs with matching distributor

nozzles. Accessory hot water and

steam coils and electric heaters are

also available.

Easier installation and service

The multiposition design and com-

ponent layout help you to get the unit

installed and running quickly. The

DX coils have factory-installed TXVs

with matching distributor nozzles.

Units can be converted from horizon-

tal to vertical operation by simply

repositioning the unit. Drain pan con-

nections are duplicated on both sides

of the unit. The ﬁlters, motor drive,

TXVs, and coil connections are all

easily accessed by removing a single

side panel.

Selection procedure —

38AH024-034/40RM — SI

NOTE: Pages 22 and 23 contain combination ratings

for 38AH024-034 units and matching 40RM air hand-

lers. If the 38AH units are matched with 39L or 39NX air

handlers, use the Carrier AHU (Air-Handling Unit) selec-

tion program software package for combination ratings. If

TotalinetP702 water coolers are used, determine the per-

formanceby cross-plotting the condensing unit performance

found in this book against the P702 performance in the

P702 product data book. If the 38AH condensing units are

matched with 2 independent 40RM units, cross-plot for per-

formance ratings or contact Carrier Application Engineer-

ing for assistance.

I Determine cooling load, evaporator-air tempera-

ture and quantity.

Given:

Total Cooling Capacity

Required (TC) .........................60kW

Sensible Heat Capacity

Required (SHC) .......................48kW

Temperature Air Entering

Condenser (Edb) ........................36C

Temperature Air Entering

Evaporator (db/wb) ........26.7 C db, 20 C wb

Evaporator Air Quantity ...............3800 L/s

External Static Pressure ..................150Pa

Length of Interconnecting

Refrigerant Piping ...............18m(Linear)

II Select condensing unit air-handler combination.

For this example, select a 38AH024 matched with a

40RM024. (See Combination Ratings table, page 22)

This 38AH024/40RM024 condensing unit-air hand-

ler combination provides 62.5 kW of total cooling

capacity and 49.2 kW of sensible capacity at the given

conditions. If other temperatures or airﬂow values are

required, interpolate the values from the combination

ratings.

III Determine sizes of liquid and suction lines.

Enter the Refrigerant Pipe Sizes table (page 40). The

sizes shown are based on an equivalent length of pipe.

This equivalent length is equal to the linear length

of pipe indicated at the top of each sizing column, plus

a 50% allowance for ﬁtting losses. (For a more accu-

rate determination of actual equivalent length in place

of using the estimated 50% value, refer to Carrier

System Design Manual.) For this example, note in the

linear length column that the proper pipe size is

⁄

in.

for the liquid lines and 1

⁄

in. for the suction lines.

IV Determine fan rpm and bhp (brake horsepower).

At the Air Handler Fan Performance table (page 27),

enter the 40RM024 section at 3800 L/s and move to

the External Static Pressure (ESP) column. Note that

the conditions require 14.30 r/s at 2.64 kW.

V Determine motor and drive.

Enter the Fan Motor Data tables on page 41, and ﬁnd

that the standard motor for a 40RM024 unit is rated

at 3.73. Since the kW required is 2.64, a standard

motor satisﬁes the requirement and should be used.

Next, ﬁnd the type of drive that satisﬁes the 14.30 r/s

requirement in the Drive Data tables on page 42. For

a 40RM024 unit, the Standard Drive table shows an

r/s range of 11.9 to 14.6. Since the r/s required is

14.30, the standard drive satisﬁes the requirement and

should be used. Select the standard motor and stand-

ard drive combination (option code GC or ED).

Refrigerant Piping ................30ft(Linear)

II Select condensing unit air-handler combination.

For this example, select a 38AH024 matched with a

40RM024. (See Combination Ratings table, page 24.)

This 38AH024/40RM024 condensing unit-air hand-

ler combination provides 214,500 Btuh of total cool-

ing capacity and 179,000 Btuh of sensible capacity at

the given conditions. If other temperatures or airﬂow

valuesare required, interpolatethe values from the com-

bination ratings.

III Determine sizes of liquid and suction lines.

Enter the Refrigerant Pipe Sizes table (page 40). The

sizes shown are based on an equivalent length of pipe.

This equivalent length is equal to the linear length of

pipe indicated at the top of each sizing column, plus a

50% allowance for ﬁtting losses. (For a more accurate

determination of actual equivalent length in place of

using the estimated 50% value, refer to Carrier

System Design Manual.) For this example, note in the

linear length column that the proper pipe size is

⁄

⁄

in. for the suction lines.

IV Determine fan rpm and bhp (brake horsepower).

At the Air Handler Fan Performance table (page 29),

enter the 40RM024 section at 8000 cfm and move to

the External Static Pressure (ESP) column. Note that

the conditions require 954 rpm at 4.23 bhp.

V Determine motor and drive.

Enter the Fan Motor Data tables on page 41, and ﬁnd

that the alternate motor for a 40RM024 unit is rated

at 7.5 hp. Since the bhp required is 4.23, an alternate

motor satisﬁes the requirement and should be used.

Next, ﬁnd the type of drive that satisﬁes the 954 rpm

requirement in the Drive Data tables on pages 42 and

43.For a 40RM024 unit, the Medium-Static Drive table

shows an rpm range of 814 to 1018 . Since the rpm

required is 954, the medium-static drive satisﬁes the

requirement and should be used. Select the alternate

motor and medium-static drive combination (option

code TC or RD).

EXAMPLE: Supply voltage is 400-3-50.

AB = 393 v

BC = 403 v

AC = 396 v 393 + 403 + 396

Average Voltage = 3

1192

= 397

Determine maximum deviation from average voltage.

(AB) 397 − 393 = 4 v

(BC) 403 − 397 = 6 v

(AC) 397 − 396 = 1 v

Maximum deviation is 6 v.

Determine percent voltage imbalance.

% Voltage Imbalance = 100 x 397

= 1.5%

This amount of phase imbalance is satisfactory as it is below the

maximum allowable 2%.

IMPORTANT: If the supply voltage phase imbalance is more than

2%, contact your local electric utility company immediately.

Operating sequence

Within 6 seconds to 5 minutes (depending on timing logic)

from a thermostat call for the ﬁrst stage of cooling, com-

pressor no. 1 and the condenser fans start. The no. 2 fan

only starts if the outdoor ambient temperature is above

21.1 C (70 F). The oil pressure switch and the low pressure

switch are bypassed for the ﬁrst 2 minutes. If either the low

pressure switch or oil pressure switch remain open after

2minutes, the unit shuts down and goes into a lockout mode.

Theevaporator-fanmotorstarts immediatelywhenever there

is a call for cooling. If a liquid line solenoid valve has been

installed (for refrigerant control during the off cycle), then

the solenoid valve for compressor no. 1 opens immediately

upon a call for cooling.

On standard units, compressor no. 1 operates either fully

loaded or at one step of unloading, depending on the suc-

tion pressure, which is dependent on the evaporator load

conditions.

As the cooling demand increases, the thermostat calls for

the second stage of cooling. Within 6 seconds to 5 minutes

(depending on timing logic) from a call for the second stage

of cooling, compressor no. 2 starts. The oil switch and low

pressure switch for circuit no. 2 are bypassed for the ﬁrst

two minutes.

As the cooling load is satisﬁed, the thermostat stops the call

for the second stage of cooling, which in turn deenergizes

compressor no. 2, closes the no. 2 liquid line solenoid (if

installed) and energizes the compressor no. 2 crankcase

heater.

If the space temperature continues to decrease, then the

thermostat stops the call for the ﬁrst stage of cooling, which

then deenergizes compressor no. 1 and the condenser fans,

closes the no. 1 liquid line solenoid valve (if installed), and

energizes the compressor no. 1 crankcase heater.

The unit controls prevent both compressors from reener-

gizing within 5 minutes from a previous call for operation.

If the unit safeties trip during operation, then the compres-

sor remains locked out from further operation. To reset the

lockout mode, the thermostat must be forced to stop call-

ing for cooling by resetting the thermostat setting above the

space temperature and then back to the desired set point.

NOTE: If the thermostat fan switch is in the auto position,

the evaporator fan cycles on and off as the thermostat calls

for cooling (or heating). If the switch is in the continuous

position, the fan runs when the condensing unit is powered.

Installation

Select equipment to match or to be slightly less than peak

load. This provides better humidity control, less unit cycling,

and less part-load operation.

When selecting vapor line sizes, oil return must be evalu-

ated, particularly at part-load conditions.

The indoor fan must always be operating when outdoor

unit is operating.

IMPORTANT: When application is in a VAV (variable

air volume) system, total building load is not the sum

of the individual peak loads. If individual peak loads

are summed, the equipment tends to be oversized for

the load.

To minimize return-air temperature extremes, use the

equipmentroomasareturn-airplenumwhenapplyingVVTt

(variable volume temperature) systems with supply-to-return

air recycle as used with Carrier VVT control systems.

Ductwork should be sized according to unit size, not

building load.

To minimize the possibility of air recirculation, avoid the

use of concentric supply/return grilles.

Indoor equipment should be selected at no less than

40 L/s per kW (300 cfm/ton).

IMPORTANT: Condensing units applied in VVT or

VAV systems must have ﬁeld-supplied and installed

accumulators. Order 2 part number --KH--73LZ-001

from Service Parts (1 required for each refrigerant

circuit).

General

Select equipment to match or to be slightly less than peak

load. This provides better humidity control, less unit cycling,

and less part-load operation. Equipment should be selected

to perform at no less than 40 L/s per kW (300 cfm/ton).

The air handler fan must always be operating when the

condensing unit is operating.

Ductwork should be sized according to unit size, not

building load. For larger units with two fans, a split duct

transition is recommended at the fan outlets, but a plenum

can be used with slight reduction in external static pressure

capability.

For variable air volume (VAV) systems with supply-to-

return air recycling, use the equipment room as a return air

plenum.

Controls — 38AH044-084

Operating sequence

Circuits A1 and B1 are controlled by independent circuitry.

It is therefore possible to maintain partial cooling capability

even if one compressor is inoperable.

NOTE: Single-circuit units do not have independent con-

trol circuitry.

On a call for cooling, the ﬁrst-stage cooling thermostat

TC1 closes, energizing the ﬁrst stage of the condenser fans

and timer motor TM-A (TM for single-circuit units). After

12 seconds, the timer energizes lead compressor contactor

C-A1 and the lead compressor starts. (Circuit A compres-

sor is the lead on dual-circuit units, and compressor A1 is

the lead on single-circuit units.) At the same time, solenoid

drop relay SDR2 energizes and closes its contacts, which

energizes andopens liquid linesolenoid valve LLS-A(LLS-A1

for single-circuit units). Circuit A (compressor A1 for single-

circuit units) is now operational.

A set of bypass contacts in timer TM-A allows the

circuit A compressor (compressor A1 for single-circuit units)

40 seconds to build sufﬁcient oil pressure. If the oil pres-

sure is insufﬁcient after 40 seconds, circuit A (compressor

A1 for single-circuit units) shuts down and must be reset

manually.

A second set of bypass contacts in timer TM-A (TM for

single-circuit units) allows the refrigerant circuit 2

⁄

minutes

to build sufﬁcient low-side pressure. This time delay is a

start-up feature for low ambient conditions; no accessory is

required. If refrigerant circuit pressure is insufﬁcient to close

the low-pressure switch after 2

⁄

minutes, the circuit A com-

pressor (compressor A1 for single-circuit units) shuts down

for 5

⁄

minutes and then automatically attempts to restart.

No manual reset is required.

Dual-circuit units — If circuit A is insufﬁcient for the cool-

ing requirements, second-stage thermostat TC2 closes to

bring circuit B on line. Circuit B follows the same sequence

of operation as circuit A, except a relay delays circuit B

compressor start-up for 40 seconds after a call for cooling.

Because circuit A has a 12-second delay after TC1 closes,

and circuit B has a 40-second delay after TC2 closes, the

two compressors cannot start at the same time.

Optional single-circuit units — If compressor A1 is in-

sufﬁcient for the cooling requirements, second-stage ther-

mostat TC2 closes, which opens liquid line solenoid valve

LLS-A2. Compressor A2 starts only after the D-D2 con-

tacts in timer TM close (approximately 2

⁄

minutes after

compressor A1 is energized) and the suction pressure is suf-

ﬁcient to close capacity control pressure switches CCPS1

and CCPS2.

All units — When the fan switch on the thermostat is set

for automatic operation (AUTO), the ﬁeld-supplied indoor-

fan contactor (IFC) is cycled with the lead compressor. If the

fan switch is set at the continuous position (CONT), the IFC

is energized as long as the unit power is on.

NOTE: Liquid line solenoid valves must be ﬁeld-supplied

and installed at the evaporator for both dual- and optional

single-circuit units.

Controls — 38AH094-134

Operating sequence

Units are controlled with electromechanical components.

Eachrefrigeration circuit isoperated byan independent timer

motor which controls the operation sequence of each cir-

cuit. It is possible to maintain partial cooling capability even

if one circuit is inoperable.

On a call for cooling, ﬁrst stage cooling thermostat TC1

closes. Condenser fans and timer motor (TM) are ener-

gized. After approximately 7 seconds, timer contacts E-E1

close. Approximately 12 seconds after TC1 closes, nor-

mally open timer contacts B-B1 close for 1 second. This

energizes compressor A1 contacts CA1 and starts the com-

pressor. At the same time, solenoid drop relays (SDRs) and

liquid line solenoid valve no. 1 (LLS-A1) open, and timer

relay no. 1 (TR1) is energized. Normally open TR1 con-

tacts close, completing a circuit around B-B1 and through

compressor A1 contactors to maintain compressor opera-

tionwhen B-B1 contacts open. Contacts E-E1 remain closed

for approximately 40 seconds to bypass the oil pressure

switch.If oil pressureis insufﬁcientwhen contacts E-E1open,

the compressor stops, the timer cycles off, and the control

circuit locks out. At start-up, timer motor contacts D-D1 are

closed, bypassing low-pressure relay contacts LPR-A for

⁄

minutes. This provides a winter start-up feature.

Approximately 2

⁄

minutes after TC1 closes, timer con-

tacts D-D1 open and D-D2 close. If pressure is insufﬁcient

to close the low-pressure switch, the low-pressure switch

relay remains open, the compressor shuts down, and the

Time Guardtcontrol is initiated. Time Guard control pre-

vents compressor from restarting for 5 minutes after the

demand for cooling is satisﬁed.

Units 38AH094 and 104 — If circuit A operation is

insufﬁcient for the cooling requirements, the thermostat sec-

ond stage TC2 closes to bring circuit B on-line for cooling.

This circuit follows the same sequence of operation as the

lead circuit, except a 60-second time-delay relay (TDR)

delays compressor start-up for 60 seconds after the call for

cooling.

Modules 124A, 124B, 134A, and 134B — If com-

pressor A1 is insufﬁcient for the cooling requirements, the

thermostat second stage closes, which opens the liquid line

solenoid valve LLS-A2. Compressor A2 starts only after

D-D2 contacts in the timer close and the suction pressure is

sufﬁcient to close the capacity control switches.

All units — Whenthe fan switch is set for automatic(AUTO)

operation, the indoor-fan contactor (IFC) is cycled with the

lead compressor. If the fan switch is set for continuous

(CONT), the IFC is energized as long as the unit power is

on.

Restart after stoppage by safety control — The high-

pressure switch, compressor discharge gas thermostats, and

the oil pressure switch must be reset manually by breaking

the control power supply at any of the following points:

Control circuit fuse, fan motor circuit breaker, or ther-

mostat. Restart follows the Time Guardtcontrol 5-minute

delay.Stoppage by low-pressureswitchresults in Time Guard

control 5-minute delay, then unit attempts to restart.

The compressor motor overcurrent protectors are

manual-reset circuit breakers. Reset of control circuit may

also be necessary.
