Quizplus · Accepted Answer

The coefficient of performance (CP) for a Carnot air conditioner is defined as CP = Qc/W, where Qc is the heat removed from the indoors and W is the work input. Given CP = 8 and W = 10 kW, Qc = CP * W = 8 * 10 kW = 80 kW. The heat expelled to the outdoors (Qh) is the sum of the heat removed from the indoors and the work input, so Qh = Qc + W = 80 kW + 10 kW = 90 kW.
