Outside air at 38 °C db and 60% relative humidity enters a cooling and dehumidifying device at a volumetric flow rate of 3,800 m3/h. The air leaves the device at 90% relative humidity. The inside design conditions are 26 °℃ and 45% relative humidity. The sensible heat ratio is 0.75. Calculate the followings: (Assume 100% flow of outside air.) a) Apparatus dew point temperature. b) Air dew point temperature. c) Dry bulb temperature of the supply air.
