An ideal vapour-compression refrigeration cycle with refrigerant R134a as the working fluid operates with an evaporator temperature of -22 C and a condenser pressure of 0.8 MPa. The mass flow rate of the refrigerant is 0.1 kg/s. Calculate the following:

(a) pressure in the evaporator,

(b) specific entropy of the refrigerant at the exits of the evaporator and the compressor

(c) temperature and enthalpy of R134a at the exit of the compressor

(d) temperature and enthalpy of R134a at the exit of the condenser, and (e) coefficient of performance (COP) of refrigerator
