The interior of a building is maintained at 23oC by a heat pump cycle operating at steady state while receiving thermal energy from well water at 12oC. The thermal energy discharged to the building is at a rate of 116, 250 kJ/h. Over a period of 21 days, a meter reads electricity consumption of 2080 kW.h to run the heat pump. Determine:
a) the amount of thermal energy that the heat pump receives over the 21-day period from the well water , in kJ.
b) the heat pump’s coefficient of performance.
c) the coefficient of performance of a reversible heat pump cycle operating between hot and cold reservoirs at 23oC and 12oC.
