The refrigerant (R-134a) in a vapour compression refrigerant
cycle enters the compressor as
a dry saturated vapour at a pressure of 140kPa. It is
compress to a pressure of 600kPa and a
temperature of 60°C. On leaving the condenser, the refrigerant has
a dryness fraction of 0.1. The
mass flow rate of the refrigerant is 11kg/min. State three (3)
assumptions
Draw the p-h and T-s diagram and determine:
(i) Compressor power
(ii) Refrigerant capacity
(iii)Coefficient of performance
