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 C 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.

d) Cooling capacity of the air conditioner.

e) Amount of moisture removed.
