Question

a refrigerator maintains a temperature of -10C while the ambient air temperature is 30C. The heat leakage into the freezer is estimated to be at a continous rate of 2 kJ/s. Determine the least power needed to pump this heat continously.

Answer 1

Answer:

first find the COP=T(l)/T(h)-T(l)

6.575

and now the cop on the basis of output /input will e

6.575=2kw/P

P will be 0.3041 kW
