    Basic AHU PPCL Program

    Hi,

    I'm new to the industry and I'm still lost. Can anyone walk me through this Basic air handling unit program?. Thank you in advance.


    The variable volume air handler is comprised of an inlet isolation damper, chilled water and hot water control valves, and a supply fan with a VFD.

    The air handler will be enabled on a time of day schedule. When enabled, the AHU inlet isolation damper will be opened and after a delay of 30 seconds the supply fan will be enabled to operate and the VFD speed will be modulated to maintain a discharge pressure of 1.5 “wc. The hot water and chilled water valves will operate without overlap to maintain the discharge temp at 55 degF. When the air handler is disabled, both hot water and chilled water valves are closed, the isolation damper is shut and the fan speed is set to zero.

    Physical points :

    AHU1.SFAN.SS
    AHU1.SFAN.SPEED
    AHU1.ISO.DAMPER
    AHU1.CHW.VALVE
    AHU1.HW.VALVE
    AHU1.SA.TEMP
    AHU1.SA.PRESS
