Features and Benefits

20 to 120 Ton Units

Trane 20 to 120 ton air-cooled condensers have an operating range of 40F to 115F, with a lowambient option down to 0F.

The control panel is factory-installed and wired to prevent potential damage and to provide

weathertight protection.

The control panel contains:

fan motor contactors.

fan cycling controls.

terminal point connection for compressor interlock.

115-volt control power transformer.

These standard features reduce installation costs and provide easy interface with control logic.

All Trane air-cooled condenser coils are an all aluminum Microchannel design. The 20 to 30 ton

condensers are single circuit; 40 to 120 ton units are dual circuited; all feature integral subcooling.Units can have optional corrosion protected condenser coil.

Durable Construction

Trane 20 to 120 ton condensers are built for long life. The unit frame is constructed of 14 gauge

galvanized steel. Louvered panels provide excellent coil protection while enhancing unit

appearance and strength. The unit surface is phosphatized and finished with Trane Slate Grey air-

dry paint. This air dry-paint finish exceeds 500 consecutive hour salt spray resistance in accordance

with ASTM B117.

Microchannel Condenser Coils

Microchannel coils are an all aluminum coil that has

been successfully used in the automotive industry for

many years, and is now being applied in the HVACindustry. The coils have a fully-brazed construction

which increases coil rigidity making them more

rugged to withstand the rigors of jobsite handling.

Additionally, the light weight simplifies coil handling.

The all aluminum construction creates an exceptional

heat transfer capability, allowing the refrigerant

charge to be reduced to levels that exceed LEED EA-

Credit 4 requirements. Bottom line, less refrigerant is

being used, which creates a healthier and greener

environment.

Application Considerations

Certain application constraints should be considered when sizing, selecting, and installing air-

cooled condensers. Unit and system reliability depends on properly and completely

acknowledging these considerations. Consult your local Trane sales engineer if your applicationvaries from these guidelines.

Setting the Unit

A base or foundation is not required if the selected unit location is level and strong enough to

support the operating weight. Refer to the Weights section for the weight of individual units.

Isolation and Sound Emission

The most effective method of noise isolation is proper unit location. Units should be placed away

from noise sensitive areas. Structurally transmitted noise can be reduced with the use of spring

isolators and they are recommended for acoustically sensitive applications. Flexible electrical

conduit, for maximum isolation effectiveness, will reduce sound transmitted through electrical

conduit.

State and local codes on sound emissions should always be considered. Since the environment in

which a sound source is located affects sound pressure, unit placement must be carefully

evaluated.

Servicing

Recommended minimum space envelopes for servicing are located in the Dimensional Data

section and serve as guidelines for providing adequate clearance. The minimum space envelopes

also allow for control panel door swing and routine maintenance requirements.

Unit Location

Unobstructed flow of condenser air is essential to maintaining capacity and operating efficiency.

When determining unit placement, careful consideration must be given to assure a sufficient flow

of air across the condenser heat transfer surface. Two detrimental conditions are possible and must

be avoided: Warm air recirculation and coil starvation.

Warm air recirculation occurs when discharge air from the condenser fans is recycled back at thecondenser coil inlet. Coil starvation occurs when free airflow to the condenser is restricted.

Both warm air recirculation and coil starvation cause reductions in unit efficiency and capacity

because of the higher head pressures associated with them. In more severe cases, nuisance unit

shutdowns will result from excessive head pressures.

Cross winds, those perpendicular to the condenser, tend to aid efficient operation in warmer

ambient conditions. However, they tend to be detrimental to operation in lower ambients or when

hot gas bypass is used due to the accompanying loss of adequate head pressure. As a result, it is

advisable to protect air-cooled condensers from continuous direct winds exceeding 10 miles per

hour.

Debris, trash, supplies, etc., should not be allowed to accumulate in the vicinity of the air-cooled

condenser. Supply air movement may draw debris into the condenser coil, blocking spaces

between coil fins and causing coil starvation. Special consideration should be given to low ambient

units. Condenser coils and fan discharge must be kept free of snow or other obstructions to permit

adequate airflow for satisfactory unit operation.

Clearance

Vertical condenser air discharge must be unobstructed. While it is difficult to predict the degree of

warm air recirculation, a unit installed with a ceiling or other obstruction above it will lose capacity

and the maximum ambient operation will be reduced. Nuisance high head pressure tripouts may

also occur.

The inlet to the coil must also be unobstructed. A unit installed closer than the minimum

recommended distance to a wall or other vertical riser may experience a combination of coil

Application Considerations

starvation and warm air recirculation, resulting in unit capacity and efficiency reductions, as well

as possible excessive head pressures. The recommended lateral distances are listed in the

Dimensional Data section.

Voltage

Nominal voltage is the nameplate rating voltage. The actual range of line voltages at which the

equipment can satisfactorily operate is given below:

200/230-volt units ship from the factory set for operation in the 180 through 220-volt range. By

changing leads on unit transformers, the unit will operate in the 208 through 254-volt range.

Effects of Altitude

The tables in the Performance Data section are for use at sea level. At elevations substantially

above sea level, the decreased air density will decrease condenser capacity. Refer to the

Performance Adjustment Factors section to correct performance at other altitudes.

Ambient Limitations

Trane condensers are designed for year-around applications in ambients from 0F through 115F.

For operation below 0 F or above 115 F, contact the local Trane sales office.

Start-up and operation of Trane condensers at lower ambient temperatures require that sufficient

head pressure be maintained for proper operation. Minimum operating ambient temperatures for

standard unit selections and units with hot gas bypass are shown in the General Data section.

These temperatures are based on still conditions (winds not exceeding five mph.) Greater wind

velocities will result in a drop in head pressure, therefore, increasing the minimum starting andoperating ambient temperatures.

Units with the low ambient option are capable of starting and operating in ambients down to 0F,

10F with hot gas bypass. Optional low ambient units use a condenser fan damper arrangement

that controls condenser capacity by modulating in response to head pressure.

Maximum cataloged ambient temperature operation of a standard condenser is 115F. Operation

at design ambients above 115F can result in excessive head pressures. For operation above 115F,

contact the local Trane sales office.

Selection Procedures

When manually matching condensers with compressors, performance cross plotting becomes

necessary. The following procedure should be used to determine the correct condenser.

1. Determine the total cooling load. Make a prelimary compressor selection based on theexpected evaporator SST and condensing temperature.

2. Select compressors from manufacturer's data to meet the load at the evaporator SST (for chiller

low suction applications contact Trane applications) -

a. Remove the subcooling effect from the compressor performance at two or more compressor

capacity points. R-410A capacity increases 0.75% for every degree of subcooling (0.75% x

15F = 11.25%). So if compressor performance is at 15F subcooling, divide capacity by 1.1125

to get capacity at 0F subcooling. Plot these two points (SCT vs. compressor tons a 0F

subcooling) as shown in the selection example (Figure 1, p. 11).

b. Select a condenser fromFigure 3, p. 13(CAUJ-D10 assumed for this example) and read two

condenser only heat rejection points. Divide the condenser heat rejection by the compressor

N factor (Table 6, p. 11) to convert from heat rejection to net capacity (Net Tons Less

Subcooling). The N factor equals the ratio of compressor heat rejection divided bycompressor capacity at 0F subcooling. Plot these two points (SCT vs. Net Tons at 0F

subcooling) as shown in Figure 1, p. 11selection example.

Example:

Given- Total cooling load = 101 tons (1212 Mbh)

Design outdoor temperature = 95F

Assume- Evaporator SST = 45F (used in this example - application dependent)

c. As shown on Figure 1, p. 11, draw a line though the points representing the compressor

capacity at 0F subcooling. Next, draw a line through the points representing condenser net

capacity less subcooling.

d. At the point of intersection of the compressor and condenser lines draw dashed lines to the

left and bottom margins as shown in Figure 1, p. 11. The end points of these lines will show

a resultant gross capacity of 92 tons at 126.1F condensing temperature.

e. From Figure 2, p. 12calculate the percent increase in total heat rejection due to subcooling,

and multiply by the N factor (see Table 6, p. 11) to get the percent increase in net capacity

due to subcooling.

Example:

At 95Fambient and 126.1Fcondensing temperature Figure 2, p. 12shows there is a 7.8%

increase in total heat rejection due to subcooling. Table 6shows a 1.34 N factor by linear

interpolation. This yields a system capacity of 92tons x (1 + 7.8% x 1.34) = 102tons.

f. If necessary use the values in Table 7, p. 12to adjust the system capacity for altitude.

g. Compare this result with the design capacity and condensing temperature.

The required cooling load is 101 tons, therefore, the CAUJ-D10 is the proper selection.

Repeat the process steps B through G as necessary to achieve the most economic condenser

selection.Note: Note that evaporator selection must also meet performance requirements. For this

example, the evaporator needs to provide at least 105 tons at 45SST. A conservative

estimate for liquid temperature entering the evaporator is the SCT minus the design

subcooling (125.1 - 15F = 110.1F for the example above). Contact Trane Applications if

excessive refrigerant line lengths or pressure drops are required.

Mechanical Specifications

General

Factory-assembled and wired air cooled condensing unit. Units are constructed of 14-gaugewelded galvanized steel frame with 14 and 16-gauge galvanized steel panels and access doors. Unit

surface is phosphatized and finished with an air-dry paint. This air-dry paint finish is durable

enough to withstand a 1000-consecutive-hour salt spray application in accordance with standard

ASTM B117.

Refrigeration Circuits and Control

The 20 to 30 ton units are single circuit. The 40 to 120 ton units are dual circuited. All the necessary

controls to run the unit fans are provided. The control panel contains fan motor contactors, terminal

point connection for compressor interlock and 115 volt control power transformer. Standard units

will operate from 40 - 115F. All units shipped with factory installed liquid line service valves.

Condenser Coils and Fans

Condenser coils shall be pressure tested and have all aluminum Microchannel design. Direct drive

condenser fan motors have permanently lubricated ball bearings and thermal overload protection.

Low Ambient Operation

Standard ambient control allows operation down to 40F with cycling of condenser fans. Optional

low ambient allows operation down to 0F with external damper assembly for head pressure

control. Refer to Options section for details.

Options

Low Ambient Control

Low ambient allows operation down to 0F through the use of fan cycling and head pressure

control dampers. The control consists of a heavy gauge damper assembly that is modulated by an

actuator. The actuator is controlled by a low ambient control module. All components are factory-

mounted for both production and Packed Stock Plus units.

Corrosion Protected Condenser Coil

Condenser coil protection shall consist of a corrosion resistent coating that will withstand ASTM

B117 Salt Spray test for 1000 hours and ASTM G85 A2 Cyclic Acidified Salt Fog test for 2400 hours.
