A completely reversible air conditioner provides 21,000Btu/h of cooling for a space maintained at 81degF while rejecting heat to the environmental air at 91degF. Calculate the rate at which the entropies of the 2 reservoirs change and verify that this air conditioner satisfies the increase of entropy principle.
