1. 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
