A heat pump is used to extract heat from the outside atmosphere to heat the inside of a building. On a day when the outside air temperature is Tc°C, the heat pump is operating to a COP of 3.7, maintaining the inside temperature of the building at Th°C. If the building is losing heat at the rate of 53,709 kJ/hour in these conditions, determine how much power (kW) must be supplied to a heat pump? Keep two decimal places

The inventor decides to lower the temperature of the low-temperature reservoir using a Carnot refrigerator. This refrigerator is powered by the heat engine itself, not an external source, consuming part of the work output of the heat engine. Let the high temperature reservoir be at Th, the original low temperature reservoir be at T₁, and the even-lower temperature achieved by the refrigerator be Tr. a) Find the ratio of the net (available) work to the heat Qh supplied by the high-temperature reservoir. [You do not need to worry about the process of lowering part of the reservoir to Tr. Assume that this has already been done, and the Carnot refrigerator only needs to remove as much heat from the T, reservoir as the heat engine is supplying.] b) It is possible to obtain a higher net efficiency this way?
A heat pump is used to heat a house during the winter. The house is to be maintained at 20 C at all times.

A heat pump with a COP of 3.2 is used to heat a perfectly sealed house (no air leaks). The entire mass within the house (air, furniture, etc.) is equivalent to 1200 kg of air. When running, the heat pump consumes electric power at a rate of 5 kW. The temperature of the house was 7°C when the heat pump was turned on. If heat transfer through the envelope of the house (walls, roof, etc.) is negligible, the length of time the heat pump must run to raise the temperature of the entire contents of the house to 22°C is (a) 13.5 min (b) 43.1 min (c) 138 min (d) 18.8 min (e) 808 min
