engineering recuitment UPPSC AE Mock Test 2024 Refrigeration and Air Conditioning Refrigeration Cycles and Devices Vapour Compression (V-C) Cycle
In an ammonia vapour compression system, the pressure in the evaporator is 2 bar. Ammonia at exit is 0.85 dry and at entry its dryness fraction is 0.19. During compression, the work done per kg of ammonia is 150 kJ. The latent heat and specific volume at 2 bar are 1325 kJ/kg and 0.58 m3/kg, respectively. What will be its C.O.P?
