PART A ONLY ( USE IMAGE BELOW) 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. Subsequently, the vapor is compressed in an isentropic compressor to the pressure 1MPa and condensed in the condenser back to the initial saturated-liquid state. PART A - Determine the heat qL absorbed by the refrigerant in the evaporator and the compressor work win (per 1 kg of the refrigerant).
