Air Source Heat Pump - temp of refrigerant leaving evaporator
Hi Technocrats,
I am trying to design air source heat pump for water heating application. Though I have an experience in selling heat pump, but not designed nor have information.
Cosider the example:
Refrigerant-R22
Evaporating temp - 4 deg. C. (39.2 F)
Ambient air temp (flowing through evaporator) - 30 deg. C (86 F)
Temp drop across evaporator - 7 deg. C. (44.6 F)
My query:
1. How to design evaporator?
2. How to calculate heat content in refrigerant gas at evaporator outlet?
3. How to calculate, refrigerant gas temp leaving evaporator?
