Question

Six new refrigerator prototypes are tested in the laboratory. For each refrigerator, the electrical power P needed for it to operate and the maximum heat energy that can be removed per second {Q_{ m C, max}/Delta t} from its interior are given. 1)p=750 W, Qc max/ dT = 1500 J/s 2)p=1000 W, Qc max/ dT = 3000 J/s 3)p=400 W, Qc max/ dT = 1200 J/s 4)p=500 W, Qc max/ dT = 1500 J/s 5)p=500 W, Qc max/ dT = 2000 J/s 6)p=250 W, Qc max/ dT = 1000 J/s Part A Rank these refrigerators on the basis of their performance coefficient. Part B The six refrigerators are placed in six identical sealed rooms. Rank the refrigerators on the basis of the rate at which they raise the temperature of the room.

Explanation / Answer

coeff of perfmnce = Qc / W part a 4 > 2= 3 > 1 part b 1> 2=3 > 4
