As shown in the figure, Refrigerant 22 enters the compressor of an air conditioning unit operating at steady state at 40°F. 80 lb/in² and is compressed to 160°F, 200 lbs/in2. The refrigerant exiting the compressor enters a condenser where energy transfer to air as a separate stream occurs, and the refrigerant exits as a liquid at 200 lb/in², 90°F. Air enters the condenser at 80°F, 14.7 lb/in² with a volumetric flow rate of 1000 ft3/min and exits at 110°F. Neglect stray heat transfer and kinetic and potential energy effects, and assume ideal gas behavior for the air.

As shown in the figure, Refrigerant 22 enters the compressor of an air conditioning unit operating at steady state at 40°F, 80 lb/in² and is compressed to 160°F, 200 lbs/in². The refrigerant exiting the compressor enters a condenser where energy transfer to air as a separate stream occurs, and the refrigerant exits as a liquid at 200 lb/in², 90°F. Air enters the condenser at 80°F, 14.7 lb/in² with a volumetric flow rate of 1000 ft3/min and exits at 110°F.
