Selection Procedure

1. Design Criteria should be available to select a unit. These criteria include:

a. Design airflow

b. Entering air conditions

c. Total and sensible loads

d. Condenser water entering and leaving temperatures

e. External static pressure

f. Factory installed options required

FORM 145.05-EG2 (618)

• Summer

• Winter (if heating is required)

2. Based on design air ow, select the smallest unit with maximum air ow higher than

design air ow and minimum airow lower than design air ow from Unit Physical

Data Tables on page 19 through page 21. Please note that standard and high ef-

ciency units of the same size have different air ow limits.

3. Divide the design air ow by the air ow indicated at the top of the appropriate Cooling Performance Table for the selected unit and efciency, on page 22 through

page 31. Use Table 2 on page 17 to determine the correction factors for total and sensible capacities and compressor power.

4. Multiply the total and sensible capacities and compressor power from appropriate Cooling Performance Table for design air and water conditions with the correction

factors above to determine the unit capacity adjusted for the airow.

5. Determine if the cooling performance of this unit is acceptable. If not, repeat steps 2 through 4 above with a higher capacity unit.

6. If waterside economizer option is chosen, follow steps 3 and 4 above with appropriate Waterside Economizer Cooling Performance Table on page 32.

7. If hot water heating option is required, follow steps 3 and 4 with appropriate Hot Water data from Physical Data tables on page 19–20.

8. If electric heat option is required, obtain heating capacity based on electric heat capacity and unit voltage from Electric Heat Capacity Table on page 68.

9. Select ltration types and efciencies needed with corresponding air pressure drop

10. Select either airside economizer or inlet sound attenuating plenum, if required, with

11. Select half or full outlet plenum, if required, with corresponding air pressure drop

12. With all options selected, add air pressure drops of all the components selected, in-

cluding evaporator coil, to external static pressure required to determine total static pressure required for the supply air fan.

FORM 145.05-EG2 (618)

Selection Procedure (Cont’d)

13. Select appropriate fan for the unit to deliver design air ow at required static pressure. There may be more than one supply air fan option available for the unit being selected.

14. Add 5% belt drive losses to the motor BHP calculated, and select next available supply fan motor.

15. Supply fan motor heat gain in MBH, based on 93.5% motor efciency, may be calculated by multiplying above BHP plus the belt drive losses by 2.72.

16. Minimum Circuit Ampacity (MCA) of the unit may be calculated, using electrical data in Table 27 and Table 28 on page 68, as follows:

a. For units without electric heat:

MCA = 1.25 * (largest motor RLA or FLA) + (FLA or RLA of all the rest of the motor) + two transformers FLA

b. For units with electric heat, MCA is the lower of the heating and cooling mode

MCA. Cooling mode MCA is as shown in step a above.

• Electric heat less than 50 kW

Heating mode MCA = 1.25 * (electric heat FLA + supply fan motor FLA) + two transformers FLA.

• For units with electric heat 50 kW or more, MCA is the lower of the heating and cooling mode MCA

Heating mode MCA = 1.25 * supply fan motor FLA + electric heat FLA + two transformers FLA.

17. Maximum Overcurrent Protection (MOP) for the unit is calculated as follows:

a. For units without electric heat:

• MOP = 2.25 * (largest motor RLA or FLA) + (FLA or RLA of all the rest of the motor) + two transformers FLA.

b. For units with electric heat, MOP is the lower of the heating and cooling mode

MOP. Cooling mode MOP is as shown in step a above.

• Heating mode MOP = 2.25 * (electric heat FLA + supply fan motor FLA) + two transformers FLA.

c. MOP is equal to next lower fuse size available of the higher of the values cal-

culated above, unless:

• Value in step c is lower than MCA, in which case the MOP value is the next size higher than the MCA.

18. The component weights are in Table 30 on page 69 and Table 31 on page 70. Add weights of the components covered by the options selected. To obtain operating weight, add water weights corresponding to the option selected carrying water weights.
