(b) A heat pump shown in Figure Q5(b) comprises four (4) basic components. It uses R-134a as a refrigerant and utilizes 700 W to drive its compressor. During heat pump operation, its refrigerant enters the condenser at 770 kPa and 38°C at a rate of 0.02 kg/s and leaves at constant pressure as a saturated liquid. Determine: (i) the rate of heat rejected by the condenser; the rate of heat absorption from the surrounding; and the COP of the heat pump. (iii)
