A dehumidifier receives a flow of 0.25 kg/s dry air at 28oC, 80% relative humidity as shown in figure P12.105. It is cooled down to 20oC as it flows over the evaporator and then heated up again as it flows over the condenser. The standard refrigeration cycle uses R-22 with an evaporator temperature of 5oC and a condensation pressure of 1600 kPa. Find the amount of liquid water removed and the heat transfer in the cooling process. How much compressor work is needed? What is the final air exit temperature and relative humidity?
