    Hi Condenser Differential Pressure



    Pls help everyone, ASAP,

    We have two chillers here, the other one is ok, but the other one I think is getting bad.

    This RTWD trane chiller's condenser differential pressure reading in Circuit #1 is higher than circuit #2.

    Chiller 1
    Condenser Differential Pressure circuit 1: 102.5 PSID
    Approach temp. : 18.8F

    Condenser differential Pressure circuit 2: 96.5 psid
    Approach temp. : 15.9F

    The other chiller is OK and they are both newly cleaned and the chiller's condenser approach temp emediately rises. I really wonder why.

    Pls help..thank you...

    You don't say what DP gas pressure or water pressure
    Either way though it don't sound right
    Are you talking about the evaporator ?

    A lot more info needed including all running pressures and temps for both gas and water circuits
    If the World did not Suck, We would all fall off !

    OK,
    First things first, you talking about less than 5% differential, this is well within the spec of the heat exchangers.

    Your problem is likely to lay within the refrigerant circuit.
    Time to call an engineer out to look at them.
