A heat pump uses refrigerant-134a to extract heat from the outside air at -10°C to maintain a house at 15°C.The refrigerant enters the condenser at 600kPa and 25°C at a rate of 45L/min and leaves as a saturated liquid at 600 kPa. The compressor consumes 0.75kW of power.

1. Determine the rate of heat supplied to the house and, hence, the actual COP of the heat pump.

2. Determine the maximum COP.

3. Determine the actual rate of heat extraction from the outside air.
