Refrigerant 134a is a working fluid in an ideal vapor compression refrigeration cycle with a cold region at 0°C and a warm region at 26°C. Saturated vapor enters the compressor at 0°C and saturated liquid leaves the condenser at 26°C, The mass flow rate of the refrigerant is 0.08% kg/s. Determine (a) the enthalpies at states 1 and 2, (b) the compressor power (kW), (c) the enthalpy at state 4, (d) the refrigeration capacity (kJ/s) (the heat transfer rate to the refrigerant), (e) the coefficient of performance.
