An air-conditioner with refrigerant R-134a as the working fluid is used to keep

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. Determinea) The actual COPb) The maximum COPc) The minimum volume flow rate of the refrigerant atthe compressor inlet for the same compressor inlet and exit conditions.
