An air conditioning unit is being designed to provide 36,000 BTU/h (3 tons) of cooling capacity. The air conditioner will operate on a standard throttle expansion refrigeration cycle. Freon 22 will be used as the refrigerant. The evaporator will operate at a temperature of 50°F and the condenser will operate at 140°F. Determine the refrigerant flow rate, compressor power, and the thermal load on the condenser. Assume reversible compression and then consider a compression efficiency of 70%.
