    What is a typical range for discharge superheated degree in VRF systems?



    Hi -

    My question is in the title, what is a typical range for discharge superheated degree in VRF systems in cooling mode only? By discharge superheated degree I mean the difference between the discharge pipe temperature and condensing temperature.

    Thank you for your help!

    Condense around 40C, discharge pipe below 100, probably somewhere around 80, give or take a bit.

    The discharge gas temperature can range anywhere between 55C up to 100C, depending on load and ambient temperature.
    The inverter compressor safety normally kicks in around 106C by backing off the hz

    Condensing temperature is normally ambient + 15K

    Hi
    it is depends to our design in system
    and it is different in what kind of compressor you have
    is it recips or screw
    our outlet pressure is related to our ambient temp and our condenser type (air cooled or water cooled or evaporator condenser ) from that we can find our out let temp from condenser
    air cooled = ambient temp + 6 t0 10 c
    water cooled = ambient + 5 C
    also out let temp in recips compressor related to how cylinders is cooled and oil cooler temp

    Also our gas and our suction pressure is very important
    in PH diagrams if it goes down our temp goes to high side .
