****PART B ONLY In a standard ideal refrigeration cycle (Fig. 1), the refrigerant 134a enters adiabatically isolated expansion valve as a saturated liquid at a pressure P1 = 1 MPa and leaves the device at a pressure P2 = 100kPa. Then the refrigerant enters the evaporator, where it changes into the saturated vapor.
