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?
