Question 2 35 pts A heat pump operates on the ideal vapor-compression

Question 2 35 pts A heat pump operates on the ideal vapor-compression refrigeration cycle with R-134a as the working fluid. This heat pump is used to keep a space at 22 C by absorbing heat at a rate of 3.345 Btu/s from geothermal water flowing through the evaporator heat exchanger. The evaporator operates at 70 F, and the condenser pressure is 140 psia. The compressor receives work at a rate of 13.2 Btu/lbm. (i) Determine the enthalpy values for all the states (10 points) (ii) Draw a T-s diagram for the process showing all stages and known values. (5 points) Determine (i) the mass flow rate of the refrigerant (7 points), (ii) the rate of heat transfer to the heated space (7 points), and (iii) the COP (6 points).
