A window-mounted air conditioner supplies 19 m3/min of air at 15°C, 1 bar to a room. Air returns from the room to the evaporator of the unit at 22°C. The air conditioner operates at steady state on a vapor-compression refrigeration cycle with Refrigerant 22 entering the compressor at 4 bar, 10°C. Saturated liquid refrigerant at 11.5 bar leaves the condenser. The compressor has an isentropic efficiency of 70%, and refrigerant exits the compressor at 11.5 bar. Determine:

(a) the compressor power, in kW.

(b) the refrigeration capacity, in tons.

(c) the coefficient of performance.

A window-mounted air conditioner supplies 29 m3/min of air at 15°C, 1 bar to a room. Air returns from the room to the evaporator of the unit at 22°C. The air conditioner operates at steady state on a vapor-compression refrigeration cycle with Refrigerant 22 entering the compressor at 4 bar, 10°C. Saturated liquid refrigerant at 9 bar leaves the condenser. The compressor has an isentropic efficiency of 70%, and refrigerant exits the compressor at 9 bar. Determine: (a) the compressor...

Air enters a window air conditioner at 1 atm, 36oC and 75% relative humidity (??) at a rate of 12m3/min and it leaves as saturated air at 18oC. Part of the moisture in the air which condenses during the process is also removed at 18oC. Determine (a) the rate of heat (Q?) and (b) moisture removal from the air. (c) What-if Scenario: What would the rate of heat removal be if moist air entered the dehumidifier at 95 kPa instead...
