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).

A schematic of a combined refrigeration cycle and a portion of a steam power cycle is shown in the figure below. In the power cycle, steam (water) with a mass flow rate m, enters the turbine at state 1. A portion of the steam (rm,) exits the turbine at state 2 before passing through the mixing chamber. The remainder (m, - 3 kg/s) exits the turbine at state 3 and then enters a heat exchanger where it is cooled by the refrigeration cycle. The water leaves the heat exchanger at state 4 as a saturated liquid and then is pumped up to the mixing chamber pressure. R-134a with a mass flow rate of ṁg is used in the refrigeration cycle to provide cooling to the water in the heat exchanger. Properties at each state are given in the figure below. Assume that the compressor, turbine, pump, mixing chamber, throttling valve and outer walls of the heat exchanger are well insulated and neglect changes in potential and kinetic energy across all devices. a) Determine the pump work, Wp. b) Determine the…
