6-54 Refrigerant-134a enters the condenser of a residential heat pump at 800 kPa and 35 ํC at a rate of 0.018 kg/s and leaves at 800 kPa as a saturated liquid.
If the compressor consumes 1.2 KW of power, determine (a) the COP of the heat pump and (b) the rate of heat absorption from the outside air.
