A 23 600 BTU/hr air-conditioning unit has an energy efficiency ratio (EER) of 7.5. The EER is defined as the number of BTU /hr extracted from the room divided by the power consumption of the unit in watts (1 BTU = 1 .055 kJ). a) What is the actual coefficient of performance of this refrigerator ? b) If the outside temperature is 32 °C and the inside temperature is 22 OC, what percent of the theoretical maximum value is the coefficient of performance ?
