Repeat given Problem using R-134a instead of R-22 as the refrigerant.
Problem:
A vapor-compression cycle refrigerator uses R-22 as the working fluid. The evaporator temperature is -20.0°C, the condenser temperature is 40.0°C, and the flow rate of R-22 is 0.100 kg/s. If the refrigerant exits the compressor as a saturated vapor and exits the condenser as a saturated liquid, determine
a. The isentropic coefficient of performance.
b. The equivalent reversed Carnot cycle coefficient of performance.
c. The amount of refrigeration (in tons) that this system can provide.
