University SECTION B (Answer any ONE question from this section 11. A heat pump working on the ideal vapour compression cycle heals the supply to a building The heat is supplied from a nearby river at 7°C. The air is supplied at into the building at 1.013 bar and 32C at a rate of 0.5 m/s. This air is hosted at constant pressure from 10°C when it passes through the condenser of the heat pump. The refrigerant used is R134a which is dry saturated, when leaving the evaporator. There is no undercooling in the condenser. A temperature difference of 17K is required to facilitate the heat transfer from the river to the refrigerant in the evaporator. The delivery pressure of the compressor is 11 545 bar. Given R-287 /kgk and C -1.005 OK, determine the a) mass flowrate of the refrigerant [10 marks 15 marks) b) work generated by the compressor [5 marks) c) power required to drive the compressor if the mechanical efficiency is 87% d) COP 15 marks)
