A heat pump with refrigerant R22 is used for space heating between temperature limits of −20∘C and 25∘C. the heat required is 200 MJ/h. Assume specific heat of vapour at the time of discharge as 0.98 kJ/kgK. Other relevant properties are given below. The enthalpy (in kJ/kg) of the refrigerant at isentropic compressor discharge is |
