    Condensing temp in refrigeration



    I am confused with the term, "Condensing temp".
    When we say condensing temp,
    1. Is it the temp of condensing medium (in case water cooled condensor, water temp) or
    2. the refrigerant gas leaving compressor has some condensing temp? if so, how to decide?

    Regards

    Anup

    Re: Condensing temp in refrigeration

    At the compressor discharge valve, you have the discharge temeprature.
    It is the hottest measurable point in a system (the discharge valve is the hottest point)
    It is in this point that we find all the collected heat of a system.

    In the condenser, we first have a desuperheating and then we come to the condensing temperature.

    This is the biggest part in the condensor where we have a saturated condition which means that there is a relation between temperature and pressure.
    This is also the pressure - the condensing pressure - you read on your manifold and the temperature you find on the dial of your manifold or on a sliding ruler is the condensing temperature.

    When liquid leaves the condensor in the last part, it will sometimes a little bit subcooled. You still have the same condensing pressure but you now have a lower liquid temperature then the condensing temperature.

    Clarified?
    It's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.
