The window-mounted air conditioner supplies 19 m 3 /min of airat 15 8 C, 1 bar to a room. Air returns from the room to theevaporator of the unit at 22 8 C. The air conditioner operates atsteady state on a vapor-compression refrigeration cycle withRefrigerant 22 entering the compressor at 4 bar, 10 8 C. Saturatedliquid refrigerant at 9 bar leaves the condenser. The compressorhas an isentropic efficiency of 70%, and refrigerant exits thecompressor at 9 bar.

(1) Write assumptions no less than three

(2) Draw clear Schematic

(3) the compressor power, in kW, the refrigeration capacity, intons, and the coefficient of performance.
