Selection Procedure, Determine Motor and Drive

SELECTION PROCEDURE

To determine combination ratings for 569D/F, 576C and 566D/E units matched with 524A Series air handlers, follow these steps:

I DETERMINE COOLING LOAD, EVAPORATOR-AIR TEMPERATURE, AND QUANTITY.

IISELECT CONDENSING UNIT AIR-HANDLER COMBINATION.

For this example, select a 569D120 matched with a 524A-C120 with high-capacity 4-row coil This 569D120/ 524A-C120 condensing unit air-handler combination provides 130,000 Btuh of total cooling capacity and 98,200 Btuh of sensible capacity at the given conditions. If other temperatures or airflow values are required, interpo- late the values from the combination ratings.

IIIDETERMINE SIZES OF LIQUID AND SUCTION LINES.

Enter Refrigerant Piping Sizes table. The sizes shown are based on an equivalent length of pipe. This equivalent length is equal to the linear length of pipe indicated at the top of each sizing column, plus a 50% allowance for fitting losses. (For a more accurate determination of actual equivalent length in place of using the estimated 50% value, refer to a standard refrigeration piping practice.) For this example, note in the linear length column that the proper pipe size is 1/2 in. for the liquid line and 13/8 in. for the suction line.

IV DETERMINE FAN RPM AND BHP (BRAKE HORSEPOWER).

At the Air Handler Fan Performance table enter at 524A- C120 with high capacity coil at 4000 cfm and move to the External Static Pressure (ESP) column. Note that the con- ditions require 803 rpm at 1.77 bhp.

VDETERMINE MOTOR AND DRIVE.

Enter the Fan Motor Data tables and find the standard motor for 524A-C120 unit rated at 2.4 Hp. Since the bhp required is 1.77, a standard motor satisfies the require- ment and should be used.

Next, find the type of drive that satisfies the 803 rpm requirement in the Drive Data tables. For the 524A-C120 unit, the Standard Drive table on shows an rpm range of 666-863. Since the rpm required is 803, the standard drive satisfies the requirement and should be used. Select the standard motor and standard drive combination (option code GC or ED).
