DE. A reversed Carnot cycle air conditioner of 1 TR capacit operates with cooling coil temperature to = 50C. The surro air at 430C is used as a cooling medium rising to a tempera 53C. The temperature of heat rejection is ti: = 550C. The heat transfer coefcient of the heat exchanger between th working substance and the surrounding air is U = 250 W. m Determine the mass ow rate of the surrounding air enteri heat exchanger, area of the heat exchanger, CUP and pow consumption of the air conditioner. {b} If water at 3D\"C is u a cooling medium in the same heat exchanger, will its area adequate or inadequate for necessaryr heat rejection? Assu that the mass ow rate of water remains the same as that Also for water, U = 2500 W. m2 K1.[c) If the area is redu 1 m2 , what will be the temperature of heat rejection t k, temperature rise of water, CUP, power consumption, perce saving in power consumption and percentage reduction in heat-exchanger area as compared with air as a cooling m
