An air-conditioner with refrigerant-134a as theworking fluid is used to keep a room at 23°C by rejectingthe waste heat to the outdoor air at 34°C. The roomgains heat through the walls and the windows at a rate of250 kJ/min while the heatgenerated by the computer, TV, and lights amounts to 900 W. The refrigerant enters the compressorat 400 kPa as a saturated vapor at a rate of 80 L/minand leaves at 1200 kPa and 70°C. Determine (a) the actualCOP, (b) the maximum COP, and (c) the minimumvolumeflow rate of the refrigerant at thecompressor inlet for thesame compressor inlet and exit conditions.
