1. The Cool-Master is a new window air conditioner design that has a Carnot coefficient of performance (COP) of 18.9. However, its actual coefficient of performance is only 3.30. Determine the second law availability efficiency of this air conditioner.
2. A common window air conditioner has an actual COP of 7.88. If the inside temperature is T0 = TL = 75.0°F and the outside temperature is 95.0°F, then determine the second law availability efficiency of this air conditioner.
