Efficiency…

The importance of energy efficiency

cannot be understated. Fortunately,

ASHRAE has created a guideline

emphasizing its importance.

Nonetheless, energy is often dismissed

as an operational cost over which the

owner has little control. That perception

results in missed opportunities for

energy efficiency, reduced utility bills,

and higher profits. Lower utility bills

directly affect profitability. Every dollar

saved in energy goes directly to the

bottom line. Trane’s RTAC is one way to

reciprocating compressors can easily

have a failure rate four times of a helical

rotor. Combine that with two to three

reciprocating compressors for each

equal tonnage, and statistics tell you it’s

Condenser coils. Trane’s condenser

coils are manufactured with the same

philosophy as the compressors; they’re

built to last. Even though manufacturing

processes have allowed thinner and

thinner materials in their assembly, with

obvious material and manufacturing

savings, Trane’s coil material did not

change with the RTAC generation of air

cooled chillers. Substantial condenser

fins, that do not require additional

coating in non-corrosive environments,

contribute to the highest reliability

standards for air-cooled chillers in the

industry.

• Factory Testing Means Trouble-Free

Start-Up. All air-cooled Series R chillers

are given a complete functional test at

the factory. This computer-based test

program completely checks the

sensors, wiring, electrical components,

microprocessor function,

communication capability, expansion

valve performance and fans. In

addition, each compressor is run and

tested to verify capacity and efficiency.

Where applicable, each unit is factory

preset to the customer’s design

conditions; an example would be

leaving liquid temperature setpoint.

The result of this test program is that

the chiller arrives at the job site fully

tested and ready for operation.

• Factory Installed and Tested Controls/

Options Speed Installation. All Series R

chiller options, including main power

supply disconnect, low ambient

control, ambient temperature sensor,

low ambient lockout, communication

interface and ice making controls, are

factory installed and tested. Some

manufacturers send accessories in

pieces to be field installed. With Trane,

the customer saves on installation

expense and has assurance that ALL

chiller controls/options have been

tested and will function as intended.

Simple Installation

Superior Control

The Adaptive Control^™microprocessor

system enhances the air-cooled Series R

chiller by providing the very latest chiller

control technology. With the Adaptive

Control microprocessor, unnecessary

service calls and unhappy tenants are

avoided. The unit is designed not to trip

or unnecessarily shut down. Only when

the Tracer^™chiller controllers have

exhausted all possible corrective actions

and the unit is still violating an operating

limit will the chiller shut down. Controls

on other equipment typically shut down

the chiller, usually just when it is needed

the most.

• Compact Physical Size. The Trane

Model RTAC chiller averages a 20%

reduction in physical footprint, while

the greatest change is actually 40%

smaller when compared against the

previous design. This improvement

makes the RTAC the smallest air-cooled

chiller in the industry and a prime

candidate for installations that have

space constraints. All physical sizes

were changed without sacrificing the

side clearances needed to supply fresh

airflow without coil starvation.

• Close Spacing Installation. The air-

cooled Series R^™Chiller has the tightest

recommended side clearance in the

industry, four feet for maximum

performance. In situations where

equipment must be installed with less

clearance than recommended, which

frequently occurs in retrofit

applications, restricted airflow is

common. Conventional chillers may

not work at all. However, the air-cooled

Series R chiller with Adaptive Control^™

microprocessor will make as much

chilled water as possible given the

actual installed conditions, stay on line

during unforeseen abnormal

For example:

A typical five-year-old chiller with dirty

coils might trip-out on high pressure

cutout on a 100°F [38°C] day in August. A

hot day is just when comfort cooling is

needed the most. In contrast, the air-

cooled Series R chiller with an Adaptive

Control microprocessor will stage fans

on, modulate electronic expansion valve,

and modulate slide valve position as it

approaches a high pressure cutout,

thereby keeping the chiller on-line when

you need it the most.

Application

Considerations

Important

the employment of a reputable water

treatment specialist, familiar with local

water conditions, to assist in this

determination and in the establishment

of a proper water treatment program.

Water Flow Limits

Certain application constraints should be

considered when sizing, selecting and

installing Trane air-cooled Series R

chillers. Unit and system reliability is

often dependent upon proper and

complete compliance with these

considerations. When the application

varies from the guidelines presented, it

should be reviewed with your local

Trane sales engineer.

The minimum and maximum water flow

rates are given in Tables G-1 through

G-4. Evaporator flow rates below the

tabulated values will result in laminar

flow causing freeze-up problems,

scaling, stratification and poor control.

Flow rates exceeding those listed may

result in excessive tube erosion.

Effect Of Altitude On Capacity

Air-cooled Series R chiller capacities

given in the performance data tables are

for use at sea level. At elevations

substantially above sea level, the

decreased air density will reduce

condenser capacity and, therefore, unit

capacity and efficiency.

Flow Rates out of Range

Many process cooling jobs require flow

rates that cannot be met with the

minimum and maximum published

values for the Model RTAC evaporator. A

simple piping change can alleviate this

problem. For example: A plastic injection

molding process requires 80 gpm

[5.1 l/s] of 50°F [10°C] water and returns

that water at 60°F [15.6°C]. The selected

chiller can operate at these

result of an oversized chiller. In addition,

an oversized unit is usually more

expensive to purchase, install, and

operate. If over-sizing is desired,

consider using multiple units.

Ambient Limitations

Trane air-cooled Series R chillers are

designed for year-round operation over

a range of ambient temperatures. The

Model RTAC chiller will operature as

standard in ambient temperatures of 25

to 115°F [-4 to 46°C]. With the low

ambient option, these units will operate

down to 0°F [-18°C]. If an ambient

temperature as high as 125°F [51°C] is

the basis for design, the high ambient

option will permit the chiller to run

without going into a limiting condition.

For installations in areas with large

ambient differences, the wide ambient

option will allow the chiller to perform

uninhibited from 0 to 125°F [-18 to 51°C].

For operation outside these ranges,

temperatures, but has a minimum flow

rate of 120 gpm [7.6 l/s]. The system

layout in Figure A1 can satisfy the

process.

Water Treatment

Dirt, scale, products of corrosion and

other foreign material will adversely

affect heat transfer between the water

and system components. Foreign matter

in the chilled water system can also

increase pressure drop and

consequently, reduce water flow. Proper

water treatment must be determined

locally, depending on the type of system

and local water characteristics. Neither

salt nor brackish water is recommended

for use in Trane air-cooled Series R

chillers. Use of either will lead to a

shortened life to an indeterminable

degree. The Trane Company encourages

Leaving Water Temperature Limits

Trane air-cooled Series R chillers have

three distinct leaving water categories:

standard, low temperature, and ice

making. The standard leaving solution

temperature range is 40 to 60°F [4.4 to

15.6°C]. Low temperature machines

produce leaving liquid temperatures less

than 40°F [4.4°C]. Since liquid supply

temperature setpoints less than

Figure A2. Temperature out of range system layout

40°F [4.4°C] result in suction

temperatures at or below the freezing

point of water, a glycol solution is

required for all low temperature

machines. Ice making machines have a

leaving liquid temperature range of 20 to

60°F [-6.7 to 15.6°C]. Ice making controls

include dual setpoint controls and

safeties for ice making and standard

cooling capabilities. Consult your local

Trane sales engineer for applications or

selections involving low temperature or

ice making machines. The maximum

water temperature that can be circulated

through an evaporator when the unit is

not operating is 108°F [42°C].

[5.6°C]. Chilled water temperature drops

from 6 to 18°F [3.3 to 10°C] may be used

as long as minimum and maximum

water temperatures and flow rates are

not violated. Temperature drops outside

this range are beyond the optimum

range for control and may adversely

affect the microcomputer’s ability to

maintain an acceptable supply water

temperature range. Further, temperature

drops of less than 6°F [3.3°C] may result

in inadequate refrigerant superheat.

Sufficient superheat is always a primary

concern in any refrigerant system and is

especially important in a package chiller

where the evaporator is closely coupled

to the compressor. When temperature

drops are less than 6°F [3.3°C], an

evaporator runaround loop may be

required.

related energy savings as the reason that

prompted them to install a VPF system.

With the help of a software analysis tool

such as System Analyzer^™or DOE-2, you

can determine whether the anticipated

energy savings justify the use of variable

primary flow in a particular application. It

may also be easier to apply variable

primary flow in an existing chilled-water

plant. Unlike the “decoupled” system

design, the bypass can be positioned at

various points in the chilled-water loop

and an additional pump is unnecessary.

The evaporator on the Model RTAC can

withstand up to 50 percent water flow

reduction as long as this flow is equal to

or above the minimum flow rate

requirements. The microprocessor and

capacity control algorithms are designed

to handle a maximum of 10% change in

water flow rate per minute in order to

maintain 0.5°F [0.28°C] leaving

evaporator temperature control. For

applications in which system energy

savings is most important and tight

temperature control is classified as

+/- 2°F [1.1°C], up to 30 percent changes

in flow per minute are possible.

Leaving Water Temperature out of

Range

Many process cooling jobs require

temperature ranges that cannot be met

with the minimum and maximum

published values for the Model RTAC

evaporator. A simple piping change can

alleviate this problem. For example: A

laboratory load requires 120 gpm

[7.6 l/s] of water entering the process at

85°F [29.4°C] and returning at 95°F

[35°C]. The accuracy required is better

than the cooling tower can give. The

selected chiller has adequate capacity,

but a maximum leaving chilled water

temperature of 60°F [15.6°C].

Variable Flow in the Evaporator

An attractive chilled water system option

may be a variable primary flow (VPF)

system. VPF systems present building

owners with several cost-saving benefits

that are directly related to the pumps.

The most obvious cost savings result

from eliminating the secondary

In Figure A2, both the chiller and process

flow rates are equal. This is not

necessary. For example, if the chiller had

a higher flow rate, there would simply be

more water bypassing and mixing with

the expense incurred with the associated

piping connections (material, labor),

electrical service, and variable-frequency

drive. Building owners often cite pump-

Considerations

Series Chiller Arrangements

Series chiller arrangements can be

controlled in several ways. Figure A3

shows a strategy where each chiller is

trying to achieve the system design set

point. If the cooling load is less than 50

percent of the systems capabilities,

either chiller can fulfill the demand. As

system loads increase, the Chiller 2

becomes preferentially loaded as it

attempts to meet the leaving chilled

water setpoint. Chiller 1 will finish

cooling the leaving water from Chiller 2

down to the system design setpoint.

Typical Water Piping

Another energy-saving strategy is to

design the system around chillers

arranged in series. The actual savings

possible with such strategies depends

on the application dynamics and should

be researched by consulting your Trane

Systems Solutions Representative and

applying the Trane System Analyzer

program. It is possible to operate a pair

of chillers more efficiently in a series

chiller arrangement than in a parallel

arrangement. It is also possible to

achieve higher entering-to-leaving chiller

differentials, which may, in turn, provide

the opportunity for lower chilled water

design temperature, lower design flow,

and resulting installation and operational

cost savings. The Trance screw

All building water piping must be

flushed prior to making the final

connections to the chiller. To reduce heat

loss and prevent condensation,

insulation should be installed. Expansion

tanks are also usually required so that

chilled water volume changes can be

accommodated.

Staggering the chiller set points is

another control technique that works

well for preferentially loading Chiller 1. If

the cooling load is less than 50 percent

of the system capacity, Chiller 1 would

be able to satisfy the entire call for

cooling. As system loads increase,

Chiller 2 is started to meet any portion of

the load that Chiller 1 can not meet.

compressor also has excellent

capabilities for “lift,” which affords an

opportunity for savings on the

evaporator water loop.

Short Water Loops

etc. It is not recommended to locate the

equipment near occupied, sound

sensitive areas of the building or near

windows. Locating the equipment away

from structures will also prevent sound

reflection, which can increase levels at

property lines, or other sensitive points.

When physically isolating the unit from

structures, it is a good idea to not use

rigid supports, and to eliminate any

metal-to-metal or hard material contact,

when possible. This includes replacing

spring or metal weave isolation with

elastomeric isolators. Figure A4

illustrates isolation recommendations for

times the evaporator flow rate. For a

amount of volume should be increased.

To prevent the effect of a short water

volume of water in the system and,

therefore, reduce the rate of change of

chiller leaving fluid setpoint to its most

efficient setting and starts the chiller,

chiller pump, and load pump.

Trane air-cooled Series R Chillers are

well suited for ice production. An air-

cooled machine typically switches to ice

production at night. Two things happen

under this assumption. First, the leaving

brine temperature from the evaporator is

lowered to around 22 to 24°F

When electrical demand is high, the ice

pump is started and the chiller is either

demand limited or shut down

completely. Tracer controls have the

intelligence to optimally balance the

contribution of ice and chiller in meeting

the cooling load.

temperature has typically dropped about

15 to 20°F [8.3 to 11°C] from the peak

daytime ambient. This effectively places

a lift on the compressors that is similar

to daytime running conditions. The

chiller can operate in lower ambient at

night and successfully produce ice to

supplement the next day’s cooling

demands.

performance in any ice storage

application.

The ice storage system is operated in six

different modes: each optimized for the

utility cost of the hour.

The capacity of the chiller plant is

extended by operating the chiller and ice

in tandem. Tracer rations the ice,

augmenting chiller capacity while

reducing cooling costs. When ice is

produced, Tracer will lower the air-

cooled chiller leaving fluid setpoint and

start the chiller, ice and chiller pumps,

and other accessories. Any incidental

loads that persist while producing ice

can be addressed by starting the load

pump and drawing spent cooling fluid

from the ice storage tanks.

Selection

Procedure

Trane air-cooled Series R chiller

performance is rated in accordance with

the ARI Standard 550/590-1998

Certification Program. Chiller selection

assistance and performance information

can be obtained by using the Series R

chiller selection program, available

through local Trane sales offices.

Selection Example

Given:

Required System Load = 140 Tons

Leaving Chilled Water Temperature

(LCWT) = 44°F Chilled Water

Temperature Drop = 10°F Design

Ambient Temperature = 95°F

Evaporator Fouling Factor = 0.0001

The chiller capacity tables cover the

most frequently encountered leaving

liquid temperatures. The tables reflect a

10°F [5.6°C] temperature drop through

the evaporator. For other temperature

drops, apply the appropriate

To calculate the required chilled water

flow rate we use the formula given

below:

GPM = (140 Tons x 24) / 10°F = 336 GPM

Performance Data Adjustment Factors

from Table A-1. For chilled brine

selections, contact your local Trane sales

engineer. To select a Trane air-cooled

Series R^™chiller, the following

From Table P-1 (RTAC performance

data), an RTAC 140 standard at the given

conditions will produce 138.2 tons with

compressor power input of 158.6 kW

and a unit EER of 9.7.

information is required:

To determine the evaporator pressure

drop use the flow rate (GPM) and

pressure drop chart on page 16. Entering

the curve at 336 gpm, the pressure drop

for a nominal 140 standard evaporator is

16 feet.

Design load in tons of refrigeration

Design chilled water temperature drop

Design leaving chilled water temperature

Minimum Leaving Chilled Water

Temperature Setpoint

Design ambient temperature

The minimum leaving chilled water

temperature setpoint for water is 40°F.

For those applications requiring lower

setpoints, a glycol solution must be

used. Contact the local Trane sales

engineer for additional information.

Evaporator flow rates can be determined

by using the following formulas:

GPM = (Tons x 24) / Temperature Drop

(Degrees F)

L/S = (kW (Capacity) x .239) /

Temperature Drop (Degrees C)

NOTE: Flow rates must fall within the

limits specified in Tables G-1 through G-4

(for GPM or for L/s).

Notes:

1. As standard, all units have single point power connection. Optional dual point power connections are available.

2. Max Fuse or HACR type breaker = 225 percent of the largest compressor RLA plus 100 percent of the second compressor RLA, plus the sum of the condenser fan FLA per NEC 440-22.

Use FLA per circuit, NOT FLA for the entire unit).

3. MCA - Minimum Circuit Ampacity - 125 percent of largest compressor RLA plus 100 percent of the second compressor RLA plus the sum of the condenser fans FLAs per NEC 440-33.

4. RECOMMENDED TIME DELAY OR DUAL ELEMENT (RDE) FUSE SIZE: 150 percent of the largest compressor RLA plus 100 percent of the second compressor RLA and the sum of the condenser

fan FLAs.

5. RLA - Rated Load Amps - rated in accordance with UL Standard 1995.

6. Local codes may take precedence.

7. Control kW includes operational controls only. Does not include evaporator heaters.

8. XLRA - Locked Rotor Amps - based on full winding (x-line) start units. YLRA for wye-delta starters is ~1/3 of LRA of x-line units.

9. VOLTAGE UTILIZATION RANGE:

10. A separate 115/60/1, 20 amp or 220/50/1, 15 amp customer provided power connection is needed to power the evaporator heaters (1640 watts).

11. If factory circuit breakers are supplied with the chiller, then these values represent Maximum Overcurrent Protection (MOP).

12. When the circuit breaker option is ordered, two circuit breakers will be provided (one per circuit) for both single and dual point power.

13. Motor kW is for standard fans. Low noise fans at 50 Hz are rated at 1.1 kW/fan.

Notes:

1. As standard, all units have single point power connection. Optional dual point power connections are available.

2. Max Fuse or HACR type breaker = 225 percent of the largest compressor RLA plus 100 percent of the second compressor RLA, plus the sum of the condenser fan FLA per NEC 440-22.

Use FLA per circuit, NOT FLA for the entire unit).

3. MCA - Minimum Circuit Ampacity - 125 percent of largest compressor RLA plus 100 percent of the second compressor RLA plus the sum of the condenser fans FLAs per NEC 440-33.

4. RECOMMENDED TIME DELAY OR DUAL ELEMENT (RDE) FUSE SIZE: 150 percent of the largest compressor RLA plus 100 percent of the second compressor RLA and the sum of the condenser fan

FLAs.

5. RLA - Rated Load Amps - rated in accordance with UL Standard 1995.

6. Local codes may take precedence.

7. Control kW includes operational controls only. Does not include evaporator heaters.

8. XLRA - Locked Rotor Amps - based on full winding (x-line) start units. YLRA for wye-delta starters is ~1/3 of LRA of x-line units.

10. A separate 115/60/1, 20 amp or 220/50/1, 15 amp customer provided power connection is needed to power the evaporator heaters (1640 watts).

11. If factory circuit breakers are supplied with the chiller, then these values represent Maximum Overcurrent Protection (MOP).

12. When the circuit breaker option is ordered, two circuit breakers will be provided (one per circuit) for both single and dual point power.

13. Motor kW is for standard fans. Low noise fans at 50 Hz are rated at 1.1 kW/fan.

Notes:

1. As standard, all units have single point power connection. Optional dual point power connections are available.

2. Max Fuse or HACR type breaker = 225 percent of the largest compressor RLA plus 100 percent of the second compressor RLA, plus the sum of the condenser fan FLA per NEC 440-22.

Use FLA per circuit, NOT FLA for the entire unit).

3. MCA - Minimum Circuit Ampacity - 125 percent of largest compressor RLA plus 100 percent of the second compressor RLA plus the sum of the condenser fans FLAs per NEC 440-33.

4. RECOMMENDED TIME DELAY OR DUAL ELEMENT (RDE) FUSE SIZE: 150 percent of the largest compressor RLA plus 100 percent of the second compressor RLA and the sum of the condenser fan

FLAs.

5. RLA - Rated Load Amps - rated in accordance with UL Standard 1995.

6. Local codes may take precedence.

7. Control kW includes operational controls only. Does not include evaporator heaters.

8. XLRA - Locked Rotor Amps - based on full winding (x-line) start units. YLRA for wye-delta starters is ~1/3 of LRA of x-line units.

10. A separate 115/60/1, 20 amp or 220/50/1, 15 amp customer provided power connection is needed to power the evaporator heaters (1640 watts).

11. If factory circuit breakers are supplied with the chiller, then these values represent Maximum Overcurrent Protection (MOP).

12. When the circuit breaker option is ordered, two circuit breakers will be provided (one per circuit) for both single and dual point power.

13. Motor kW is for standard fans. Low noise fans at 50 Hz are rated at 1.1 kW/fan.
