Aheat pump cycle is used to maintain the interior of a building at 21°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 1490 kw ⋅ h of electricity is provided to the heat pump. determine: 1. the amount of energy that the heat pump receives over the 14-day period from the well water by heat transfer, in kj. 2. the heat pump’s coefficient of performance. 3. the coefficient of performance of a reversible heat pump cycle operating between hot and cold reservoirs at 21°c and 9°c.
