please anwser task 2

Mollier or Pressure/enthalpy charts is another alternative to obtain a quick and initial performance estimation of refrigeration/heat pump cycles used in heating, ventilation and air-conditioning (HVAC) system. Your role in a company that provide design and installation services for air -conditioning (AC) system is provide preliminary performance estimation. You have been given the following design specifications: The system design specifications are as follows: Refrigerant HFC-134a as the working fluid Ideal cycle operation condition is assumed Cycle is operated at high pressure line of 0.8 MPa Cycle is operated at low temperature line of – 10° C - Flow rate is 0.05 kg/sec Your manager asked you to make use of pressure/enthalpy chart provided for HFC-134a refrigerant in the Appendix.A to estimate the following: Task.1 1. Construct TS-plot. 2. Refrigeration effect (RE), heat of compression (HOC), and heat of rejection (HOR) and their corresponding rate/power values. 3. Estimate the COPR and COPHP 4. Determine the low-pressure line value. Task.2 1. Construct didactic sketches, showing the operating principles of both heat pumps and refrigeration systems 2. Estimate the reversible COP values, if the low and high medium temperature are as for the evaporator and condenser.
