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.
