Shahen Fakhraldin Refrigeration Systems Homework: - A 200 RT unit operate on refrigerant R134a, has a six cylinders reciprocating compressor with clearance factor of 3% and runs at 1000 rpm. The refrigerant leaves the evaporator at 217Kpa and 0°C the pressure loss in the suction valve is 17Kpa. The compressor discharge pressure is 7.7bar and a pressure loss of 46Kpa exit in the discharge valve. The refrigerant has a temperature of 24C at the inlet of the expansion valve. Assume the compressor index is equal to 1.4 and calculate: a. Compressor volumetric efficiency. b. Compressor displacement. c. Shaft power if mechanical efficiency 75%. d. Heat reject by the condenser. din
