railway RRB JE (CBT I + CBT II) Mock Test 2024 Refrigeration and Air Conditioning Refrigeration Cycles and Devices Heat Engine, Heat Pump and Refrigerator
Which equation describes the relationship between the coefficient of heat pump, the coefficient of the refrigerator and the heat engine CORRECTLY?
1
(COP)HP = (COP)Refrigerator - 1
2
(COP)HP - (COP)Refrigerator = 0
3
(COP)HP = 1 + (COP)Refrigerator
4
(COP)HP + 2 = (COP)Refrigerator
