engineering recuitment UPPSC AE Mock Test 2024 Refrigeration and Air Conditioning Refrigeration Cycles and Devices Vapour Compression (V-C) Cycle
In a simple vapour compression refrigeration cycle, the enthalpy at point 1, 2 and 4 are 260 kJ/kg, 60 kJ/kg and 180 kJ/kg, respectively, as shown in the figure. If 2 kg of refrigerant is used to cool the system, then COP of the refrigerator will be:
