    Heat exchange problems on chillers.

    Hello, I am with a chiller with screw compressor and tube bundle exchanger.
    The problem is the little exchange between the exchanger inlet and outlet and the return of liquid refrigerant to the compressor.
    I also found almost zero head loss between the exchanger inlet and outlet.
    I am convinced that the septa (diaphragms) have broken, in your opinion is it possible?
    Has this happened to you already?
    Thank you.

    Brand? Model? Do you have any readings/measurements? Anything possible with speculation.
    "Right" is not the same as "Wise".

    Don't step on my favorite part of the Constitution just to point out your favorite part.

    That is likely a plate and frame subcooler.....or an economizer.

    Check the superheat on the suction line returning to the compressor.

    But yeah, can’t help much without more information.
