Ammonia is the working fluid in a vapor-compression heat pump system with a heating capacity of 7500 W. The condenser operates at 1.70 MPa, and the evaporator temperature is -25 C. The refrigerant is a saturated vapor at the evaporator exit and a liquid is 40 C at the condenser exit. Pressure drops in the flows through the evaporator and condenser are negligible. The compression process is adiabatic, and the temperature at the compressor exit is 200 C. a COMEPLETE THE FOLLOWING a) Draw a block diagram of the thermodynamic cycle. Mark the principal states b) Draw the T-S diagram of the cycle. Mark the principal states clearly c) Clearly define the assumptions of your model d) Calculate the refrigerant mass flow rate, in kg/s e) Calculate the enthalpy value at all four principle states. Show your work and present your final answers in a table format f) Determine the compressor power input g) Determine the isentropic compressor efficiency h) Determine the coefficient of performance of the heat pump
