A refrigerator cycle has a COP of 3 and removes 100kW of heat from a building, which is kept at 23C. The device rejects heat to an energy reservoir at 33C. What is the net entropy change in this process? What is the maximum possible temperature of the high temperature reservoir to still satisfy the second law of thermodynamics?
