engineering recuitment HPCL Engineer Mock Test 2024 Refrigeration and Air Conditioning Refrigeration Cycles and Devices Vapour Compression (V-C) Cycle
In the working of a vapour-compression refrigeration plant, the following enthalpies are recorded at salient points in the cycle:
1) Enthalpy at inlet to compressor (saturated vapour), h1 = 300 kJ/kg
2) Enthalpy at outlet of compressor (after isentropic compression), h2 = 330 kJ/kg
3) Enthalpy at exit of condenser (saturated liquid), h3 = 150 kJ/kg
What is the COP of the plant?
