Features and Benefits

Deluxe Self-Contained air conditioners,
available in 3–15 tons, are single package
units designed for low cost installation in
the conditioned space or equipment
room. Durable construction, strict quality
control, and demanding factory testing
ensure reliability from start-up through
years of operation.

All units are shipped fully factory as­sembled and tested, thereby reducing
field labor, installation time, and costs.
They can also be easily converted from
vertical to horizontal discharge arrange­ments to match most building configura­tions. Discharge can be either free or
ducted. Power and water connections can
be made from either side of the unit
adding to the unit flexibility.

Application

CCRA Air-Cooled

CCRA Unit Location

Unobstructed condenser airflow is
essential to maintain capacity and
operating efficiency. When determining
unit placement, give careful consider­ation to assure sufficient airflow across
the condenser coils. Avoid these two
detrimental conditions: warm air recircu­lation and coil starvation.

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.

Considerations

Clearance

Ensure vertical condenser air discharge is
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 experience
a capacity reduction that will reduce the
maximum ambient operation. Nuisance
high head pressure tripouts may also
occur.

The coil inlet must also be unobstructed.
A unit installed closer than the minimum
recommended distance to a wall or other
vertical riser will experience a combina­tion of coil starvation and warm air
recirculation. This may result in unit
capacity and efficiency reductions, as
well as possible excessive head pres­sures. Reference the service clearance
section on page 45 for recommended
lateral distances.

Condenser

Ambient Limitations

Standard ambient control allows opera­tion down to 45°F (7.2°C) with cycling of
condenser fans. Units with the low
ambient option are capable of starting
and operating in ambient temperatures
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.

Maximum cataloged ambient tempera­ture 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

Selection Procedure

The selection of a deluxe self-contained
unit can be accomplished in three easy
steps.

Step 1 - Load

Determine the load requirements for
heating and cooling (include outside air)
using Trane’s load estimate program or
any standard method.

Step 2 - Unit Type

Self-contained air conditioners are
available in either water-cooled or
remote air-cooled models to match
individual needs.

Step 3 - Select the Unit

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

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

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 con­denser water delta T must be adjusted to
reflect the higher cfm.

Self-Contained

Design cfm = 2,400
Nominal cfm = 2,000 + 20% of nominal
cfm

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

Multiply the capacities by the correction
factors:

66 MBh x 1.03 = 68.0 MBh
45 MBh x 1.05 = 47.3 MBh

The SCWB-B50 meets the total and
sensible design requirements.

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 tempera­ture of 93.3°F. The leaving condenser
water temperature is within the design
delta T of 10°F.

Refer the fan data Table PD-1 on page 14
to determine approximate brake horse­power and fan rpm:

Fan brake horsepower = 1.09 bhp
Fan rpm = 934 rpm

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

Refer to the Trane psychrometric chart to
determine leaving air temperatures.

Notes:

1. All units operate with R-22. Water-cooled units ship with full operating charge. Air-cooled units ship with a dry nitrogen
holding charge.

2. Hot water coils do not have turbulators. See Capacity DataTables PD-19 and PD-20 for coil capacities.

3. Steam Coil capacities are shown in Table PD-21.

4. Maximum cfm limits are set to prevent moisture carryover on the evaporator coil.

5. Minimum cfm limits are set to ensure stable thermal expansion valve operation at low load conditions.

6. SCWB/SIWB/SCRB/SIRB 3, 5, 7.5, and 10 ton units are rated at ARI Standard 210/240-1994. SCWB/SIWB/SCRB/SIRB 15-ton
units are rated at ARI Standard 340/360-2000.
