SELECTION PROCEDURE

Determine cooling and heating requirements at design

conditions:

Given:

REQUIRED COOLING CAPACITY (TC) 34,500 BTUH......

SENSIBLE HEAT CAPACITY (SHC) 42,000 BTUH.........

REQUIRED HEATING CAPACITY (SHC) 42,000 BTUH.....

CONDENSER ENTERING AIR TEMPERATURE 95°F(35_C)

INDOOR--AIR TEMPERATURE 80°F (26.6_C) EDB, 67°F...

(19.4_C) EWB

EVAPORATOR AIR QUANTITY 1200 CFM...............

ELECTRICAL CHARACTERISTICS 230--1--60.............

Select unit based on required cooling capacity

Enter Net Cooling Capacities table at condenser entering

temperature of 95°F(35_C). The 36 unit at 1200 CFM and 67°F

(19.4_C) ewb (entering wet bulb) will provide a total capacity of

34,600 Btuh and a SHC of 24,200 Btuh. Calculate SHC correction,

if required, using Note 4 under Cooling Capacities tables.

Select heating capacity of unit to provide design condi-

tion requir

ement

In the Heating Capacities and Efficiencies table on page 4, note that

the unit 36060 will provide 49,000 Btuh of capacity with an input

of 60,000 Btuh.

Select unit that corresponds to power source available

The Electrical Data table shows that the unit is designed to operate

at 208/230--1--60.
