An 18,000 Btu/h air conditioner running at full load is used to keep a room at 22 deg. C in an environment at 33 deg. C. The power input to the compressor is 3.4 kW. Determine (a) the rate of heat rejected in the condenser, in kJ/h, (b) the COP of the air conditioner, and (c) the rate of cooling, in Btu/h, if the air conditioner operated as a Carnot refrigerator for the same power input.
