Slader A heat pump cycle is used to maintain the interior of a building at 15°C. At steady state, the heat pump receives energy by heat transfer from well water at 9°C and discharges energy by heat transfer to the building at a rate of 120,000 kJ/h. Over a period of 14 days, an electric meter records that 2000 kW · h of electricity is provided to the heat pump. Determine the following (13 points) : (a) the amount of energy that the heat pump receives over the 14-day period from the well water by heat transfer, in kJ; (b) the heat pump’s coefficient of performance.; EGMN 204 Spring 2020 4 (c) the coefficient of performance of a reversible heat pump cycle operating between hot and cold reservoirs at 15°C and 9°C.
