Question

(A) A standard vapour compression cycle developing 40 kW of refrigeration using refrigerant 134a operates
with a condensing temperature of 35°C and an evaporating temperature of -10°C. Calculate (a) the refrigerating
effect in kilojoules per kilogram, (b) the circulation rate of refrigerant in kilograms per second, (e) the power
required by the compressor in kilowatts, (d) the coefficient of performance, (e) the volume flow rate measured
at the compressor suction, and (f) the compressor discharge temperature.
