4.A reversible refrigeration cycle operates between cold and hot reservoirs at temperatures TC and TH, respectively. If the coefficient of performance is 3.3 and TH = 75°F, determine TC, in °F. 5.A reversible refrigeration cycle operates between cold and hot reservoirs at temperatures TC and TH, respectively. If TC = -26°C and TH = 40°C, determine the coefficient of performance.
