A completely reversible air conditioner provides 34,000 Btu/h of cooling for a space maintained at 70°F while rejecting heat to the environmental air at 110°F. Calculate the rate at which the entropies of the two reservoirs change. The rate at which the entropies of the two reservoirs change is Btu/h·R. Does this air conditioner satisfy the increase of entropy principle?
