An air-conditioner with refrigerant R-134a as the working fluid is used to keep the room at 23C by rejecting waste heat to the outdoor at 37C. The room gains 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 enters the compressor at 400 kPa as a saturated vapor at a rate of 100 L/min and leaves at 1200 kPa and 70C. Determine

a) The actual COP,

b) The maximum COP,

c) The minimum volume flow rate of the refrigerant at the compressor inlet for the same compressor inlet and exit conditions.
