The Flotronic™ Plus Chiller Com-

bines These Extra-Performance Fea-

tures for Increased Energy Savings:

• microprocessor-based control

system

• electronic expansion valve

• increased part-load efficiency

• multiple compressors — extra ca-

pacity steps

Features/Benefits

30HR,HS units are designed

for easy installation and

maintenance

Starting with installation, these ma-

chines keep costs low. Each is

completely factory engineered and

assembled to ensure a perfectly bal-

anced refrigeration system that can be

installed with minimal field labor.

Only external fluid and power connec-

tions need to be completed at the

jobsite to make the fluid-cooled (30HR)

units operational. Condenserless (30HS)

units require the addition of a remote

condenser.

The 30HR model is a packaged

unit complete with cooler, condensers,

compressors, controls, refrigerant

and oil charge, and internal piping and

wiring. The 30HS unit is a condens-

erless version of the basic 30HR,

shipped with a holding charge of refrig-

erant and specially designed for ap-

plications with remote fluid- or

air-cooled, or evaporative type, con-

densers. All the easy-rigging 30H

series chillers are extremely trim and

compact. They can pass easily

through standard doorways, and re-

quire minimal floor space on the job.

30HR,HS

Model E

Reciprocating Liquid Chillers

Nominal Capacities:

70 to 160 Tons (250 to 560 kW)

Copyright 1994 Carrier Corporation Form 30HR,HS-4PD

Rated in accordance with

ARI Standard 590-92.

Additional features ensure smooth,

trouble-free operation. Compres-

sors are mounted on heavy-duty spring

vibration isolators to minimize poten-

tially damaging vibration transmis-

sion to the building structure. Sound-

deadening mufflers dampen hot gas

pulsations. Servicing is made easy by

bolted, readily-accessible semi-hermetic

compressors that can be removed

with minimal field labor when adjust-

ments or repairs are needed.

Flotronic™ Plus control sys-

tem regulates the refriger-

ant cycle for optimum

efficiency

The 30HR,HS Flotronic Plus chillers

feature an electronic expansion valve

(EXV) operated by a microprocessor-

based control system. The system

monitors safety functions and controls

unit capacity to maintain leaving

chilled fluid temperature. The micro-

processor controls loading and un-

loading of compressors to match

changing cooling load requirements.

The control system consists of a

control box with a keypad and display

module, an EXV for each refrigera-

tion circuit, and thermistors (tempera-

ture sensors) which provide analog

inputs to the microprocessor. The

control also operates a quick test pro-

gram to check input and output sig-

nals to and from the microprocessor.

The 30HR,HS control system is self

contained and can operate on a

stand-alone basis if desired.

Components

The control box — All the

microprocessor-based controls re-

quired to optimize chiller operation

and protect it against unsafe con-

ditions are contained in the control

box. This includes the processor mod-

ule, relay module, EXV driver mod-

ule, keypad and display module, relays,

and transformers. The box has a

hinged door for ready access.

The EXV driver — The driver posi-

tions the EXVs (based on commands

from the microprocessor) and

monitors the status of the oil and

refrigerant pressure switches.

The keypad and display module

—This module consists of a key-

pad with 11 function keys and 12 nu-

meric keys (0 to 9,.,-)andan

alphanumeric 8-character liquid crystal

display. The module allows the op-

erator to perform the following

functions:

• read and change set point

• configure unit

• run quick test unit checkout

• observe diagnostic information

• schedule chiller operation

Control features

Leaving fluid temperature control

with return compensation —

The rate at which the compressors

are turned on will depend on the dif-

ference between the actual leaving

fluid temperature and the set point,

the rate of change of leaving fluid

temperature, the return fluid tempera-

ture, and the number of compressor

stages on. The control is primarily

from leaving fluid temperature, and

the other factors are used as compen-

sation. Because the control operates

from leaving fluid, the chiller is in-

dependent of cooling gpm (L/s). It is a

true droopless control.

Return temperature reset — The

control system is capable of han-

dling leaving fluid temperature reset

based on return cooler temperature.

Because the change in temperature

through the cooler is a measure of the

building load, the return temperature

reset is in effect an average build-

ing load reset method. All sensors re-

quired to activate return reset are

standard with the unit.

Space and outdoor-air tempera-

ture reset — Space temperature

reset and outdoor-air temperature

reset allow for the reset of the leaving

fluid temperature based on an exter-

nal temperature sensor. (Accessory

thermistor required.)

Energy management system reset

—Many energy management sys-

tems have the capability to transmit a

4 to 20 mA signal in proportion to

the desired leaving chilled-fluid set

point. The Flotronic Plus chillers have

the ability to recognize a propor-

tioned signal to establish the reset

condition (field-installed components

are required).

Remote alarm — Upon initialization

of an alarm condition, an internal

contact will close to activate a signal

suitable for remote alarm activation.

Load shed (demand limit) — A

2-step demand limit can be pro-

grammed through the Flotronic Plus

controls. The control limits total power

draw of the unit by controlling the

number of steps of capacity operating

during the demand limiting period.

Pulldown control — Pulldown con-

trol is used to minimize compressor

usage and reduce the peak kW that

occurs at start-up, when the cooler

fluid temperature is very warm but the

load is small. When activated, this

feature limits the pulldown rate to

1° F (.56° C) per minute.

Unit checkout (quick test) — The

quick test feature allows determination

of the status (on or off) of various

Flotronic Plus control components (i.e.,

solenoid valves, compressors, and

unloaders). When the unit is in standby

mode, these steps will energize these

components and indicate whether

or not the components are operational.

Diagnostics — The Flotronic Plus

control system features extensive self-

diagnostics as standard. The display

will show a 2-digit diagnostic code,

and will scroll an explanation of the

code for failures that cause the unit to

shut down, terminate a reset option,

or use a default value as set point.

Time schedule — The Flotronic Plus

control system has an integral func-

tion that allows scheduling of the cir-

culating pump and chiller operation

for up to 8 occupied/unoccupied peri-

ods per schedule, with 7 different

schedule days.

Increased part-load perfor-

mance reduces operating

costs

Multiple compressors — Multiple

compressors on a refrigerant cir-

cuit further enhance part-load effi-

ciency. This allows compressor to

operate fully loaded with 100% of

cooler and condenser surface active at

50% unit capacity, optimizing evapo-

rating and condensing temperatures.

Since the chiller normally works at

part load for 97% of its operating

time, a substantial reduction in operat-

ing cost can be realized.

Suction cutoff unloading — Un-

loading on 06E compressors eliminates

unnecessary pumping of refrigerant

gases during unloader operation. This

substantially reduces part-load power

consumption.

Liquid refrigerant subcooling —

Integral subcooler uses coldest

condenser fluid to increase system

capacity without extra horsepower.

Features/Benefits (cont)

Safety features provide

protection and increase

reliability

Auto. lead/lag control — Control

balances operating hours between

refrigerant circuits.

Standby protection — If a malfunc-

tion or safety cutout occurs, these

2-circuit chillers have the capability for

standby operation. This benefit is

especially desirable in commercial ap-

plications where even brief equip-

ment shutdowns can be extremely

costly.

Electronic expansion valve (EXV)

—The EXV is controlled to main-

tain approximately 20 F (11 C) refrig-

erant superheat entering the

compressor cylinders. (Ordinary ther-

mostatic expansion valves typically

operate at 45 F [25 C] superheat

entering compressor cylinders.) Pre-

cise superheat control is obtained

through actuation of the 760-step,

long-stroke,

3

⁄

4

-in. (19 mm) valve

positioner to ensure optimized refrig-

erant metering. The accurate refrig-

erant metering provided by the EXV

reduces compressor motor temperature

and extends motor life.

Filter drier — Refrigerant circuits are

kept free of harmful moisture and

contaminants by a factory-installed

filter drier.

Crankcase heater — The compres-

sor crankcase heater protects the

compressors against refrigerant migra-

tion and oil dilution.

Moisture-indicating sight glass —

Easy-to-read color indicator immedi-

ately shows moisture content of refrig-

erant system.

Oil pressure safety switch —

Safety switch shuts compressor(s) off if

the oil pressure drops below a safe

operating point.

Protection against single-phasing

—Manual reset, magnetic trip cir-

cuit breakers protect the compressor

motors against both overload and

single-phasing, and eliminate potential

problems before they become ser-

vice headaches.

Motor overtemperature protec-

tion — Servicing dollars are saved

because the compressor motors are

thoroughly protected against overheat-

ing by quick-sensing elements.

Other safeties — Additional safeties

include: Loss of refrigerant charge

protection, low fluid flow protection,

low chilled fluid temperature pro-

tection, low and high superheat pro-

tection, low oil protection for each

compressor circuit, and low con-

trol voltage (to unit) protection.

Thermistors — Six thermistors are

used for temperature sensing inputs to

microprocessor (a seventh may be

used as a remote temperature sensor

for space or outdoor-air tempera-

ture reset):

• Cooler leaving and entering (return)

chilled fluid temperature control

• Cooler saturation temperatures —

Circuit A and Circuit B

• Return gas temperatures entering

compressor cylinder —Circuit A

and Circuit B

• Remote temperature sensor

limit steps: 1) between 50% and 100% of maximum com-

pressor displacement; or 2) between 0% and 49% displace-

ment. The external switching device determines when to

limit unit capacity.

Chilled Fluid Flow Switch — Although low fluid flow de-

tection is provided by the unit internal control devices, this

accessory is available for field installation for redundant

protection.

Oil-pressure safety switch — Standard on condenser-

less (30HS) models, accessory on fluid-cooled (30HR) mod-

els. Switch protects compressors against loss of oil pressure

in the event of a loss of lubricating oil. One switch package

is needed for each lead compressor.

Application data

Leveling unit

To assure proper oil return, be sure that unit is level,

particularly in its major lengthwise dimension, as com-

pressor oil return piping runs in that direction.

Determine prior to installation if any special treat-

ment is required to assure a level installation.

Cooler fluid temperature

1. Maximum leaving chilled fluid temperature (LCWT) is

70 F (21 C). Unit can start and pull down with up to

95F (35C) enteringfluid temperaturedue toMOP (maxi-

mum operating pressure) feature of the expansion valve.

For sustained operation, it is recommended that enter-

ing fluid temperature not exceed 85 F (29 C).

2. Minimum LCWT is 40 F (4 C) for standard units. Spe-

cial order medium temperature brine units must be

ordered for operation with leaving fluid temperatures

in the range of 39 to 15 F (4 to −9 C). For ratings

below 40 F (4 C) LCWT, contact your local Carrier

representative.

Condenser fluid temperature

1. Maximum leaving condenser fluid temperature is

104 F (40 C) on all 30HR models (except 30HR160,

which has a maximum temperature of 120 F [49 C]).

2. Minimum entering condenser fluid temperature without

condenser flow regulation is 70 F (21 C).

temperature rise

Ratings and performance data in this publication are for a

cooling temperature rise of 10° F (5.6° C). Units may be

operated at a different temperature rise, provided flow lim-

its are not exceeded and corrections to capacity, etc., are

made. For minimum flow rates, see Minimum Cooler and

Condenser Fluid Flow Rates and Minimum Loop Volume

table on this page. High flow rate is limited by pressure drop

that can be tolerated. If another temperature rise is used,

apply LCWT correction as given in Selection Procedure sec-

tion on page 17.

Minimumcooler flow—This value (maximumcooler tem-

peraturerise) for standard units isshown in Minimum Cooler

and Condenser Fluid Flow Rates and Minimum Loop Vol-

ume table. When gpm (L/s) required is lower (or rise is

higher), follow recommendations below:

a. Multiple smaller chillers may be applied in series, each

providing a portion of the design temperature rise.

b. Chilled fluid may be recirculated to raise flow rate. How-

ever, mixed temperature entering cooler must be main-

tained at a minimum of at least 5° F (2.8° C) above the

leaving chilled fluid temperature.

c. Special cooler baffling is required to allow minimum flow

rate to be reduced 12%.

NOTE: Recirculation flow is shown below.

Maximum cooler flow (.5 gpm/ton or ,5° F rise

[.0.09 L/s •kW or ,2.7° C rise]) — The rise results

in practical maximum pressure drop through cooler.

Return fluid may bypass the cooler to keep pressure drop

throughcooler withinacceptable limits. Thispermits ahigher

DT with lower fluid flow through cooler and mixing after

the cooler.

Special cooler baffling is available by special order, to per-

mit a cooler flow rate increase of 10%.

Application data (cont)

Minimum fluid-cooled condenser flow — This value

(maximum rise) is shown in Minimum Cooler and Con-

denser Fluid Flow Rates and Minimum Loop Volume table

on page 13. Condensers may be piped in series. Ensure

leaving fluid temperature does not exceed 104 F (40 C).

Variable cooler flow rates —These rates may be applied

to standard chillers. However, the unit will attempt to main-

tainaconstant leavingchilledfluid temperature.Insuch cases,

minimum flow must be in excess of minimum flow given in

the Minimum Cooler and Condenser Fluid Flow Rates and

Minimum Loop Volume table, and flow rate must change

in steps of less than 10% per minute. Apply 6 gal per ton

(6.5 L per kW) fluid loop volume minimum if flow rate

changes more rapidly.

Chilled fluid loop volume — The volume in circulation

must equal or exceed 3 gal per nominal ton of cooling

(3.25 L per kW) for temperature stability and accuracy in

normal air conditioning applications. See Minimum Cooler

and Condenser Fluid Flow Rates and Minimum Loop Vol-

ume table on page 13. (For example, a 30HR100 would

require 294 gal [1112.8 L] in circulation in system loop —

see Minimum Cooler and Condenser Fluid Flow Rates and

Minimum Loop Volume table on page 13.) For process jobs

where accuracy is vital, or for operation at ambient tem-

perature below 32 F (0° C) with low unit loading conditions,

there should be from 6 to 10 gal. per ton (6.5 to 10.8 L

per kW). To achieve this volume, it is often necessary to

install a tank in the loop. Tank should be baffled to ensure

there is no stratification, and that water (or brine) entering

tank is adequately mixed with liquid in the tank.

NOTE: Tank installation is shown below.

PERFORMANCE CORRECTIONS

1. Corrected Cooling Capacity = Rated Cooling Capacity x all correc-

2. Corrected Compressor Power Input = Rated Power Input x all cor-

rection factors.

Cooler and fluid-cooled condenser freeze

protection

If chiller or fluid lines are in an area where ambient con-

ditions fall below 32 F (0° C), it is recommended that an

antifreeze solution be added to protect the unit and fluid

piping to a temperature 15° F (8.3° C) below the lowest

anticipated temperature. Corrections to performance as in-

dicated in Capacity Correction and Selection Procedure sec-

tions on pages 15 and 17 must be applied.

Useonly antifreeze solutions approved forheat exchanger

duty. Use of automotive antifreezes is not recommended

because of the fouling that can occur once their relatively

short-lived inhibitor breaks down.

Ifnot protectedwith anantifreeze solution, draining cooler

and outdoor piping is recommended if system is not to be

used during freezing weather conditions.

30HS condenser requirements

1. Ensure each refrigerant circuit has its own head pres-

sure control.

2. Condenser must provide 15° F (8.3° C) subcooling, a

maximum of 40° F (22.2° C) difference between satura-

ted condensing temperature and outdoor ambient

temperature (to prevent overload at high ambient

temperatures), and a minimum of 20° F (11.1° C) dif-

ference (to assure subcooling).

3. Do not manifold independent refrigerant circuits into a

single condenser.

4. Condenser should not be located more than 50 ft

(15 m) below chiller to maintain subcooling.

5. Design discharge and liquid piping according to Carrier

System Design Manual.

TANK INSTALLATION

14

Oversizing chillers

Oversizing chillers by more than 15% at design conditions

must be avoided as the system operating efficiency would

be adversely affected (resulting in greater and/or excessive

electrical demand and cycling of compressors). When future

expansion of equipment is anticipated, install a single chiller

tomeet present loadrequirements, and installa second chiller

to meet the additional load demand.

It is also recommended that the installation of 2 smaller

chillers be considered where operation at minimum load is

critical. The operation of a smaller chiller loaded to a greater

percent of minimum is preferred to operating a single chiller

at or near its minimum recommended value.

Hot gas bypass should not be used as a means to allow

oversizing chillers. Hot gas bypass should be given consid-

eration where substantial operating time is anticipated be-

low the minimum unloading step.

Multiple chillers

Where chiller capacities required are greater than can be

furnished by a 30H chiller, or where standby capability is

desired, chillers may be installed in parallel. Units of equal

size help to ensure balanced fluid flows. Where a large tem-

perature drop (.25° F [13.9° C]) is desired, chillers may

be installed in series. Fluid temperature sensors need not

be moved for multiple chiller operation.

Part-wind start

Part-wind start is not generally required on 30H chillers due

to use of multiple small compressors allowing smaller elec-

trical load increments, but it is available if required. Maxi-

mum instantaneous current flow (see ICF in Electrical Data

table on page 29) should be used in determining need.

Vibration isolation

Compressors are spring isolated. External vibration isola-

tion is not generally required.

Strainers

For 30HR units, a strainer with a minimum of 20 mesh

should be installed in both the cooler and condenser fluid

inlet lines just ahead of the cooler and condenser, and as

close to the cooler and condenser as possible. For 30HS

units, this recommendation applies only to the cooler.

Capacity correction (antifreeze)

If unit or fluid lines connected to the unit are in an area

where ambient temperature falls below 32 F (0° C), it is

stronglyrecommended that antifreeze(or other suitablebrine)

be used in the chilled fluid circuit. Unit performance data

must be corrected as shown in the following example (us-

ing inhibited ethylene glycol solution):

glycol (EG) solution required to protect the sys-

denserless models appear on pages 22 and 26. Ratings for

30HS condenserless models in combination with air-cooled

condensers appear on pages 23-24, and 27-28. Ratings

data beyond limits shown and/or brine ratings are available

in Carrier Application Data publications.

1. All performance data is based on:

a. Coolerwater temperaturerise of10° F (5.6° C). When

more accuracy is desired, correct LCWT by amount

determined from LCWT Correction curve below be-

fore entering Performance Data tables.

b. Cooler fouling factor of .00025 (.000044) (same for

condenser on 30HR).

c. 10° F (5.6° C) subcooling (30HS).

d. Refrigerant 22.

2. Whencorrected LCWT isused, cooler pressuredrop must

also be corrected for the new LCWT:

a. Enter Performance Data table at corrected LCWT.

By interpolation, determine corrected Capacity (tons

or kW), saturated discharge temperature (in Perfor-

mance Data tables on pages 21 and 25 for 30HS

condenserlessunits),andkW (compressor motorpower

input at rated voltage).

b. Calculate:

corrected gpm = corrected capacity (tons) x 24

temperature rise (°F)

corrected L/s = corrected capacity (kW) x .239

temperature rise (°C)

c. Enter Cooler Pressure Drop curve at corrected gpm

(L/s) and find pressure drop.

Where cooler water temperature rise is less than 7° F

(3.9° C), the high flow rate will normally be accom-

plished by excessive pressure drop. In these cases, con-

tact your local Carrier representative for selection of a

cooler with suitable baffle spacing.

Combining 30HS units with remote condensers which

have greater than (less than) the 10° F (5.6° C)

subcooling in the ratings increases (decreases) system

capacity. To adjust capacity, multiply capacity ratings by

0.96; then adjust this result upward by 0.4% for each

degree F (0.7% for each degree C) of available

subcooling.

30HS ARI (Air Conditioning and Refrigeration Institute,

U.S.A.) ratings are based on:

• Leaving chilled water temperature of 44 F (6.7 C).

• Entering cooler water temperature of 54 F (12.2 C).

• Saturated discharge temperature of 120 F (48.9 C).

30HR ARI ratings are based on:

• Leaving chilled water temperature of 44 F (6.7 C).

• Entering cooler water temperature of 54 F (12.2 C).

• Entering condenser water temperature of 85 F

(29.4 C).

• Condenser flow of 3 gpm per ton (0.054 L/s per kW).

LEGEND AND NOTES

Two electrical power circuits are required. A separate

entrance and a terminal block are provided for each cir-

cuit. Run 6 wires to unit from disconnect switch, 3 to

each circuit.

For size 110 units, the upper value is circuit A and lower

value is circuit B. For other size units, the value given is

per electrical circuit.

For all unshaded areas: Only 1 power circuit is required,

with a single entrance. Run 3 wires to unit, to a single

terminal block.

ICF — Maximum Instantaneous Current Flow during starting (the

point in the compressor starting sequence where the

sum of the LRA for the starting compressor plus the RLA

for all running compressors is maximum).

Not for wire

sizing.

kW — Maximum allowable power input (each compressor).

LRA — Locked Rotor Amps.

MCA — Minimum Circuit Amps (for wire sizing); complies with

NEC, Section 430-24 (U.S.A. Standard).

MFA — Maximum FuseAmps; 225% of largest compressor RLA

plus 100% of remaining compressor RLA. Size down to

the next standard fuse size.

MkW — Maximum unit power input.

MTA — Must Trip Amps (compressor circuit breaker).

NEC — National Electrical Code (U.S.A.).

Rec Fuse

Amps —Recommended dual element fuse amps; 150% of larg-

est compressor RLA plus 100% of remaining compres-

sor RLA. Size up to next standard fuse size.

RLA — Rated Load Amps.

*Units are suitable for use on electrical systems where voltage supplied

to the unit terminals is not below or above the listed range limits.

†Circuits and compressors are numbered from left to right when viewed

from the front of the unit.

NOTES:

1. Maximum incoming wire size for 208/230 v is as follows:

Units 070-090 have one terminal block, 3 wires, 500 kcmil.

Units 100-160 have 2 terminal blocks, 3 wires per block, 500 kcmil.

2. Maximum incoming wire size for 460 and 575 v is as follows:

Wire size maximum is 500 kcmil for units 070-160.

Units 070-120 have one terminal block, 3 wires; units 140 and 160

Control sequence

Standby—During unit offcycle whenthe RUN/STANDBY

switch is in the STANDBY position, the crankcase heaters

and the control system are energized.

NOTE: The control circuit power must be on at all times

even when the main unit power is off.

Run — When the RUN/STANDBY switch is moved from

STANDBY to RUN position, there will be a 1

1

⁄

2

minute de-

lay while the microprocessor monitors data. If in occupied

mode, after 1

1

⁄

2

minutes the chilled fluid pump will start. If

there is a call for cooling, the first compressor will start un-

loaded. The first circuit to start may be circuit A or B due to

the automatic and random lead/lag feature.

Capacity control sequence

On a call for cooling, the control system starts the initial

compressor. The control will randomly select either circuit

A or B. The liquid line solenoid valve remains closed for 10

seconds after the initial compressor on that refrigeration

circuit starts (unless the compressor has run in the 15 min-

utes prior to the latest call for cooling). This permits a pum-

pout cycle at start-up to minimize refrigerant floodback to

the compressor. If the compressor has run in the 15 min-

utes before the call for cooling, the pumpout cycle is

eliminated.

After the pumpout, the liquid line solenoid valve and the

EXV open.

The EXV will open gradually to provide a controlled

start-up to prevent liquid floodback to the compressor. Also

during this period, the oil pressure switch will be bypassed

for one minute.

As additional cooling is required, the control system will

ramp up through the capacity steps available until the load

requirement is satisfied. As capacity steps are added, com-

pressors are added, alternating between the lead and lag

refrigerant circuits. The speed at which capacity is increased

or decreased is controlled by the temperature deviation from

the set point and the rate of change in the chilled fluid

temperature.

When the second or lag refrigeration circuit is started,

that circuit will go through a 10-second pumpout unless the

circuit has been operating in the 15 minutes prior to this

start.

Upon load reduction, the control system will unload the

unit in the reverse order of loading until the capacity nearly

matches the load. Each time the lead compressor in a cir-

cuit is cycled off, the liquid solenoid valve and EXV will be

closedfor 10 seconds prior tocompressor shutdown to clear

the cooler of liquid refrigerant.

To stop unit, move the RUN/STANDBY switch to the

STANDBY position. Any refrigeration circuit that is oper-

ating at this time will continue to run for 10 seconds to

complete the pumpout cycle.
