An assembly hall was to have an air conditioning unit installed which would be maintained at 24°C dry bulb and at 50% Relative humidity. The unit delivers air at 14°C dry bulb and the calculated sensible heat load is 140 kW and the latent heat load is 50 kW. Twenty five percent by weight of extracted air is made up of outside air at 32°C dry bulb and 18°C welt bulb temperatures while 75% is extracted by the air conditioner from the assembly hall. The atmospheric pressure is 100 kPa and Rair is 287.08 j/kg-k. Using Psychrometric chart determine; a. The mass of circulating air b. The amount of moisture pick-up in the space c. The capacity of the supply fan d. The air conditioning refrigeration capacity in TOR e. The dry bulb temperature entering the air condition
