SELECTION PROCEDURE (WITH EXAMPLE)

I DETERMINE COOLING AND HEATING REQUIRE- MENTS AT DESIGN CONDITIONS:

Given:

Required Cooling Capacity (TC) . . . . . . . . . . 35,000 Btuh Sensible Heat Capacity (SHC) . . . . . . . . . . . 25,000 Btuh Required Heating Capacity . . . . . . . . . . . . . . 60,000 Btuh Condenser Entering Air Temperature . . . . . . . . . . . . 95 F Indoor-Air Temperature . . . . . . . . . . . 80 F edb, 67 F ewb Evaporator Air Quantity . . . . . . . . . . . . . . . . . . . 1200 Cfm External Static Pressure . . . . . . . . . . . . . . . . . . 0.1 in. wg Electrical Characteristics . . . . . . . . . . . . . . . . . . 208-1-60

IISELECT UNIT BASED ON REQUIRED COOLING CAPACITY.

Enter Net Cooling Capacities table at condenser entering temperature of 95 F. Unit 583A--036 at 1200 cfm and 67 F ewb (entering wet bulb) will provide a total capacity of 35,000 Btuh and a SHC of 25,200 Btuh. Calculate SHC correction, if required, using Note 4 under Cooling Capaci- ties tables.

IIISELECT HEATING CAPACITY OF UNIT TO PROVIDE DESIGN CONDITION REQUIREMENTS.

In the Heating Capacities and Ef®ciencies table on page 4, note that the unit 583A--036090 will provide 71,910 Btuh with an input of 88,000 Btuh.

IV DETERMINE FAN SPEED AND POWER REQUIRE- MENTS AT DESIGN CONDITIONS.

Before entering the air delivery tables, calculate the total static pressure required. From the given example, the Wet Coil Pressure Drop Table, and the Filter Pressure Drop table on page 16, ®nd at 1200 cfm:

External static pressure

0.1 in. wg

Wet Coil

0.1 in. wg

Filter

0.2 in. wg

Total static pressure

 

0.4 in. wg

 

Enter the table for Dry Coil Air Delivery Ð Horizontal and Down¯ow Discharge on page 15. For 208 v operation, de- duct 10% from value given. At 0.4 ESP (external static pressure), the fan will deliver 1213 cfm at medium speed. The fan speed should be set at medium speed.

V SELECT UNIT THAT CORRESPONDS TO POWER SOURCE AVAILABLE.

The Electrical Data table on page 20 shows that the unit is designed to operate at 208-1-60.
