an air conditioner with r-134a as the working fluids is used to keep a room at a constant 26 degrees C by rejecting the waste heat to the outdoor air at 34
degress C. The room gain heat through the walls and the windows at a rate of 250 KJ/min while the heat generated by the computer TV and lights amounts to 900
W. The refrigerant enter the adiabatic compressor at 500 kPa as saturated vapor at a rate of 100 L/min and leaves at 1200 kPa and 50 degress C. note:
compressor work is the work input to this refrigerator (air conditioner)
