engineering recuitment BHEL Engineer Trainee Mock Test 2025 Refrigeration and Air Conditioning Refrigeration Cycles and Devices Vapour Compression (V-C) Cycle
An ideal vapour compression refrigeration system works on the evaporator temperature of 0°C and condenser temperature of 40°C. The refrigeration effect is found to be 100 kJ/kg and specific work input to the compressor is found to be 50 kJ/kg. What will be the coefficient of performance of the refrigeration system?
