Trane deluxe integral air-cooled self-contained air conditioners are single packaged units, built for
the needs of the retrofit market.The unit’s design makes it perfect for buildings where the roof
cannot support additional load and/or there is no outside area for a remote condenser.The SCIJ
models with R-410A, meet today’s need for a high efficiency, high capacity, air conditioning unit in
a compact, versatile package. All models are AHRI certified to ASHRAE standard 90.1-2010.
These units can handle the increased capacity demands of today’s buildings without the expense
of an increase in ductwork or power wiring size.They will easily pass through doors, hallways, and
elevators without having to tear out walls or use expensive rigging. The units are designed for
quick, easy installation.
Flexibility is the key toTrane's integral air-cooled vertical self contained units. Verticalunits are field
convertible to horizontal discharge. Industrial coatings for the condenser and evaporator coils, hot
water and steam coils are standard options offered to meet any application need.

Selection Procedure
The selection of an integral air-cooled unit can be accomplished in three easy steps.
1. Select unit
2. Fan speed and bhp for:
a. Evaporator fan
b. Condenser fan
3. Supply air temperature DB
Sample Unit Selection
Following is an example unit selection procedure.
Design Conditions
•80°F/67°F DB/WB return air
•95°F ambient
•109,300 Btu/h total net
•76,500 Btu/h sensible net
•0.3 external static pressure (evaporator fan)
•4400 cfm
•0.2 external static pressure (condenser fan)
•3000 feet altitude
1. Select Unit
109,300 Btu/h
12,000 Btu/h per ton
Therefore, initially select a 10-ton unit.
- Using Table 11, p. 15
•80/67°F EAT
•4400 cfm
•95°F ambient = 10 ton capacity = 118.2 MBh total Gross, 93.6 MBh sensible Gross
– Determine the altitude correction using Table 5, p. 10:
•3000 feet = correction factor of 0.965
•Corrected total capacity = 118.2 x 0.965 = 114.06 MBh
•Corrected sensible capacity = 93.6 x 0.965 = 90.32 MBh
2. Fan Speed and bhp Determination
First, calculate the total static pressure, as shown below:
EvaporatorCondenser
0.3 esp0.2 esp
UsingTables Table 7, p. 11, and Table 6, p. 10,
•Evaporator
– 10-ton unit at 4400 cfm and 0.3 esp: rpm = 728, bhp = .91
•Condenser
– 10-ton unit at 0.2 esp: rpm = 585, bhp = 1.25
= 9.1 tons
PKG-PRC019C-EN5

Selection Procedure
Note: If values fall between cfm or esp values, interpolate values. Do not extrapolate beyond
•Calculate fan motor heat using the equation:
Therefore, 3.0 x .91 = 2.73 MBh.
•Calculate the required net total capacity using the following formula: net MBh
3. Supply Air Temperature
values in this catalog. Contact your local Trane representative for assistance as needed.
– fan motor heat (MBh) = 3.0 x fan motor bhp (see the evaporator fan performance tables)
– capacity = gross MBh capacity - fan motor heat (MBh)
Total net capacity = 114.06 - 2.73 = 111.33 MBh
Sensible net capacity = 90.32 - 2.73 = 87.59 MBh
Required - 109,300 Btu/h total net
76,500 Btu/h sensible net
Provided - 111.33 MBh total net
87.59 MBh sensible net
The 10-ton unit is the correct choice for this application.
Leaving Air Temperature (F) =T1 - Hs / (CFM x 1.08)
T1 = Entering Dry Bulb Temperature (F)
Hs = Net Sensible Heat (Btuh)
CFM = Total air flow in cubic feet/min
