Air enters the evaporator section of a window air conditioner at 14.7 psia and 90°F with a volume flow rate of 200 ft3 /min. Refrigerant-134a at 20 psia with a quality of 30 percent enters the evaporator at a rate of 4 lbm/min and leaves as saturated vapor at the same pressure. Determine (a) the exit temperature of the air and (b) the rate of heat transfer from the air.

An air conditioner using refrigerant-134a as the working fluid and operating on the ideal vapor-compression refrigeration cycle is to maintain a space at 36°C while operating its condenser at 1600 kPa. Determine the COP of the system when a temperature difference of 4°C is allowed for the transfer of heat in the evaporator. (Take the required values from saturated refrigerant-134a tables.)

Atmosphric air at 40 F and 50% relative humidity enters the heating section of an airconditioning device at a volumetric flow rate of 100ft^3/min. Water vapor is added to the heated air to increase the relative humidity to 55%. The temperature after the heating section is 72F and the temperature at the exit is 74F. Using the appropriate fomulas: a) determine the rate of the heat transfer in Btu/min. b) determine the mass flow of water vapor in lbm/min.

Refrigerant 134a is the working fluid in a vapor-compression heat pump system with a heating capacity of 60,000 Btu/h. The condenser operates at 240 lbf/in.2, and the evaporator temperature is 0°F. The refrigerant is a saturated vapor at the evaporator exit and a liquid at 110°F at the condenser exit. Pressure drops in the flows through the evaporator and condenser are negligible. The compression process is adiabatic, and the temperature at the compressor exit is 180°F. Determine (a) the mass...
