Functional Performance Test Checklist - Multizone Air Handling Unit
For Air Handling Unit:
[_____]
Ensure that a slight negative pressure exists on inboard side of the
outside air dampers throughout the operation of the dampers. Modulate OA,
RA, and EA dampers from fully open to fully closed positions.
1. Functional Performance Test: Contractor shall verify operation of air
handling unit as per specification including the following:
a. The following shall be verified when the supply and return fans
operating mode is initiated:
(1) All dampers in normal position. _______________________________
(2) All valves in normal position. ________________________________
(3) System safeties allow start if safety conditions are met. _____
b.
Occupied mode of operation - economizer de-energized.
(1) Outside air damper at minimum position. _______________________
(2) Return air damper open. _______________________________________
(3) Relief air damper [at minimum position] [closed]. _____________
(4) Chilled water control valve modulating to maintain cold deck
supply air temperature set point. __________________________________________
(5) Hot water control valve modulating to maintain hot deck supply
air temperature set point input from outside air temperature controller.
_____________________________________________________________________________
c.
Occupied mode of operation - economizer energized.
(1) Outside air damper modulates to maintain mixed air temperature
set point. _________________________________________________________________
(2) Relief air damper modulates with outside air damper according
to sequence of operation. __________________________________________________
(3) Chilled water control valve modulating to maintain cold deck
supply air temperature set point. __________________________________________
(4) Hot water control valve modulating to maintain hot deck supply
air temperature set point input from outside air temperature controller.
_____________________________________________________________________________
d.
Unoccupied mode of operation
(1)
All dampers in normal position.
_____________________________
(2) Verify low limit space temperature is maintained as specified
in sequence of operation.
_________________________________________________
e.
The following shall be verified when the supply and return fans off
