Sketch an ideal vapour-compression refrigeration cycle on p-v, t-s and p-h diagrams, and describe the processes that make up this cycle. (4 marks) list the properties of an ideal refrigerant. (3 marks) an ideal vapour-compression refrigeration cycle uses refrigerant-134a as a working fluid in an air- conditioning system. the refrigerant enters the compressor as a saturated vapour at 5°c and leaves the condenser as a saturated liquid at 55°c. the mass flow rate of the refrigerant is 0.7 kgs-1. heat transfer to the refrigerant in the evaporator is from a reservoir at 15°c, and the refrigerant in the condenser is cooled by heat transfer to the environment, which is at a temperature of 45° • the heat-transfer rate in the condenser the heat-transfer rate in the evaporator • the coefficient of performance of the cycle
