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.

expansion valves.

Head Pressure Control with Two Two-Way Valves

When the entering condenser water temperature is below 55 ºF and/or the use of waterside economizer is not available, two factory installed and controlled modulating head pressure control two-way valves shall be provided. Valve actuators shall be controlled through the factory installed main unit control system to maintain refrigerant head pressure by reducing the water flow as necessary through to allow proper functioning of thermostatic expansion valves.

When unit is the mechanical cooling mode, compressors shall be enabled when the condenser water switch is made. Mechanical cooling shall be disabled when the condenser water flow switch opens during the operation for longer than 10 seconds, and all compressors shall be turned off.

Dirty Filter Switch

A factory installed and wired pressure switch senses the air pressure differential across the filters. When the differential pressure exceeds 1.0 iwg (adjustable), the normally open contacts close. This signals the unit controller that the filters are loaded and are in need of a change.

Duct High Pressure Limit Switch

Factory installed and wired pressure switch senses the air pressure differential between the unit inlet and fan outlet. When the differential exceeds the set point for safe operation of the duct system and the unit, the unit is shut off and an alarm is generated.

Should unit dismantling and reassembly be required, the contractor shall bear the cost for this work and ensure the manufacturer’s warranty is not voided.

BUILDING AUTOMATION SYSTEM (BAS) INTERFACE

BACnet® MS/TP communication protocol shall be available.

Common Alarm Output

This binary output signal is used to indicate an alarm signal. When the unit controller has processed an alarm condition, the normally closed dry contacts shall open. When the alarm has been cleared, the contacts shall return to the normal closed position.

Outdoor Air Damper Output

Occupied/Unoccupied output signal on/off signal is used to control the outdoor air damper. Off corresponds with a closed damper and open with a fully open damper for outdoor air.

VAV Box/Heat

This binary output signal is used to put the VAV box in a heating or cooling mode. When the normally open contacts are closed, this represents a heating mode, and the VAV box should be at the maximum position. When the normally open contacts are open, this represents a cooling mode, and the VAV box should be in the cooling mode and maintaining the space/zone temperature. Voltage for the device(s) connected to the output needs to be provided from another source.

External Stop (Fan Stop)

This binary input signal is used to shut the unit down in an emergency. When the signal is open, the unit is in the shut down emergency mode. Thus, the unit is in the unoccupied mode. When the signal is closed, the unit shall be operating in the typical. After the unit has been in the emergency mode, when the signal is closed, the unit shall be controlled in the normal manner. Reset is not needed unless an alarm condition has occurred.

Cool/Heat Enable

The keypad shall be used to enable or disable cooling and heating and allow the unit to be in the fan on mode. In the fan on mode for VAV units, the unit shall control duct static pressure.

OPTIONAL ACCESORIES

The outdoor air damper and return air damper shall be controlled in a reverse-acting fashion by the unit controller.

Economizer operation shall be controlled to maximize free cooling operation based on outdoor air conditions. If outdoor air is suitable for cooling, the outdoor air dampers shall modulate to maintain temperature set point. If the outdoor air cannot satisfy the cooling load, mechanical cooling shall assist the pre-cooling to achieve temperature set point. To maximize energy savings, the economizer shall pre-cool until disabled by the enthalpy or temperature. When the economizer is disabled, the outdoor air dampers shall be set to the minimum position of 15% (keypad adjustable).
