    Temperature glide or something else?



    Hi,

    I need some explanation regarding pressure and temperature of evaporation. I was working on a heat pump 60 kW refrigerant R407c, I've made some hydraulic reconstructions and charged it with completely with new refrigerant R407C - 16 kg.
    The heat pump is working good but I measured the refrigerant pressure at the inlet of the evaporator and it was 7 bar which is about 14 C evaporation temperature but the outlet water is cooled to 7 C??? (condensation is about 22 bar). So the question is: does it happen some temperature glide inside the evaporator or is something else?

    It would be easier to diagnose if you gave us all the data...

    Pressures
    Temp of water in and out
    Temp of refrigerant after the condensor and the evaporator

    Would be a good start.

    Something's not right, 'cause the temperature of the refrigerant r407c is greater than the temperature at the outlet?
