An air conditioner operating at steady-state takes in moist air at 27 oC, 1 bar, and 70 % relative humidity. The moist air first passes over a cooling coil in the dehumidifier unit and some water vapor is condensed. The rate of heat transfer between the moist air and the cooling coil is 2,321 kJ/min. Both saturated air and condensate streams exit the dehumidifier unit at 12 oC. The moist air is then passes through the heating unit. In the heating unit the moist air is heated to 24 oC without adding any moisture.
a) Show the processes on a schematic psychometric chart.
b) Calculate the mass flow rate of dry air.
c) Calculate the rate at which water is condensed.
