An air conditioner operating at steady state takes in moist air at 28°C, 1 bar, and 70% relative humidity. The moist air first passes over a cooling coil in the dehumidifier section and some water is condensed. The rate of heat transfer between the moist air and the cooling coil is11 tons (a "ton of refrigeration is common measure of refrigeration capacity).Saturated moist air and condensate streams exit the dehumidifier unit at the same temperature. The moist air then passes through a heating unit, exiting at 24°C, 1 bar, and 40% relative humidity.
Determine:
a.The temperature of moist air leaving the dehumidifier unit, in°C.
b.The volumetric flow rate of air entering the air conditioner,in m3/min.
c.The rate of water condensed, in kg/min.
d.The rate of heat transfer to theair passing through the heating section.
