14-85 Atmospheric air from the inside of an automobile enters the evaporator section of the air conditioner at 1 atm.27°C and 50 percent relative humidity. The air returns to the automobile at 10°C and 90 percent relative humidity. The passenger compartment has a volume of 2 m³ and 5 air changes per minute are required to maintain the inside of the automobile at the desired comfort level. Sketch the psychro-metric diagram for the atmospheric air flowing through the air conditioning process. Determine the dew point and wet bulb temperatures at the inlet to the evaporator section, in°C. Determine the required heat transfer rate from the condensation of water vapor in the evaporator section, in kg/min.
