Considerations Condenser

CCRA Unit Location

Clearance

Ambient Limitations

Unobstructed condenser airflow is

essential to maintain capacity and

operating efficiency. When determining

unit placement, give careful consider-

ation to assure sufficient airflow across

the condenser coils. Avoid these two

detrimental conditions: warm air recircu-

lation and coil starvation.

Ensure vertical condenser air discharge is

unobstructed. While it is difficult to

predict the degree of warm air recircula-

tion, a unit installed with a ceiling or

Standard ambient control allows opera-

tion down to 45°F (7.2°C) with cycling of

condenser fans. Units with the low

ambient option are capable of starting

other obstruction above it will experience and operating in ambient temperatures

a capacity reduction that will reduce the

maximum ambient operation. Nuisance

high head pressure tripouts may also

occur.

down to 0°F (-17.8°C). Optional low

ambient units use a condenser fan

damper arrangement that controls

condenser capacity by modulating

damper airflow in response to saturated

condenser temperature.

Both warm air recirculation and coil

starvation cause reductions in unit

efficiency and capacity because of the

higher head pressure associated with

them. In more severe cases, nuisance

unit shutdowns will result from excessive

head pressures.

The coil inlet must also be unobstructed.

A unit installed closer than the minimum

recommended distance to a wall or other Maximum cataloged ambient tempera-

vertical riser will experience a combina-

tion of coil starvation and warm air

recirculation. This may result in unit

capacity and efficiency reductions, as

well as possible excessive head pres-

sures. Reference the service clearance

section on page 45 for recommended

lateral distances.

ture operation of a standard condenser is

115°F (46.1°C). Operation at design

ambient above 115°F can result in

excessive head pressures. For operation

above 115°F, contact the local Trane sales

office.

Selection

Procedure

Self-Contained

Design cfm = 2,400

Nominal cfm = 2,000 + 20% of nominal

cfm

Selection Procedure

The selection of a deluxe self-contained

unit can be accomplished in three easy

steps.

Refer to Table PD-6 on page19 to obtain

the capacity correction factors for +20%

of nominal cfm:

Cooling capacity multiplier = 1.03

Sensible capacity multiplier = 1.05

Step 1 - Load

Determine the load requirements for

heating and cooling (include outside air)

using Trane’s load estimate program or

any standard method.

Multiply the capacities by the correction

factors:

66 MBh x 1.03 = 68.0 MBh

45 MBh x 1.05 = 47.3 MBh

Step 2 - Unit Type

Self-contained air conditioners are

available in either water-cooled or

remote air-cooled models to match

individual needs.

The SCWB-B50 meets the total and

sensible design requirements.

Step 3 - Select the Unit

Subtract the entering water temperature

from the leaving water temperature to

determine condenser water delta T of

8.1°F. Multiply the delta T by the cooling

capacity correction factor of 1.03 to

obtain the new delta T of 8.3°F and add

this to the entering water temperature to

obtain the actual leaving water tempera-

ture of 93.3°F. The leaving condenser

water temperature is within the design

delta T of 10°F.

The conditions under which the unit must

operate and the design load will give the

final selection.

Selection Example

Design conditions for a water-cooled unit:

Entering air temperature = 80/67°F

Total gross capacity required = 64,400

Btu/h

Entering water temperature = 85°F

Leaving water temperature = 95°F

Airflow = 2,400 cfm at 0.5-inch duct static

pressure

Refer the fan data Table PD-1 on page 14

to determine approximate brake horse-

power and fan rpm:

Fan brake horsepower = 1.09 bhp

Fan rpm = 934 rpm

Unit Selection

Tentatively select a 5-ton unit: Model

SCWB-B50. Refer to Table PD-10 on

page 21 to obtain gross total and sensible

unit capacities, gpm, and leaving water

temperature at nominal conditions:

Total capacity = 66 MBh

Determine net capacities by subtracting

fan motor heat from gross capacities:

2.8 X 1.09 bhp = 3.1 MBh

Net total capacity = 67.8 MBh - 3.1 MBh

= 64.7 MBh

Net sensible capacity = 48.7MBh - 3.1

MBh = 45.6 MBh

Sensible capacity = 45 MBh

Water flow rate = 20 gpm

Leaving water temperature = 93.1°F

Since the design cfm is greater than the

nominal cfm, the capacities and con-

denser water delta T must be adjusted to

reflect the higher cfm.

Refer to the Trane psychrometric chart to

determine leaving air temperatures.

Electrical Data

Determination of Maximum Fuse Size

(MFS) and Maximum Circuit Breaker Size

(MCB)

MFS and MCB = 2.25 x largest motor

amps (FLA or RLA) + the sum of the

remaining motor amps.

Electrical Data Calculations

RLA = Rated Load Amps

Compressor LRA = Locked Rotor Amps

Fan Motor LRA = Locked Rotor Amps,

N.E.C. Table 430 - 151

FLA = Full Load Amps, N.E.C.

Table 430 - 150

If the rating value determined does not

equal a standard current rating of over

current protective device, use the next

lower standard rating for the marked

maximum rating.

Voltage utilization range is 10 percent

Determination of Minimum Circuit

Ampacity (MCA)

MCA = 1.25 x largest motor amps (FLA

or RLA) + the sum of the remaining motor

amps.

Note: MFS for CXRA units is for non-time

delay fuses.
