An air conditioning system is to take in air at1 atm,35∘Cand80%relative humidity and deliver it at22∘Cand50%relative humidity. The air flows over the cooling coils, where it is cooled and dehumidified, and then over the resistive heating wires, where it is heated to the desired temperature. Assuming that the condensate is removed from the cooling section at10∘C, determine: a) the temperature of the air before it enters the heating section and the amount of the condensed water removed, b) the amount of heat removed in the cooling section and c) the amount of heat transferred in the heating section, both inkJ/kgof dry air. (May use psychometric chart)
