Repeat given Problem using R-134a instead of R-22 as the refrigerant.

Problem :
A vapor-compression cycle refrigeration system using R-22 has an evaporator temperature of -20.0°C and a condenser temperature of 20.0°C. The refrigerant exits the compressor as a saturated vapor and exits the condenser as a saturated liquid. Determine

a. The isentropic coefficient of performance of this system.

b. The coefficient of performance of a Carnot refrigerator operating between the same temperature limits.

c. The "tons" of isentropic refrigeration per unit mass flow rate of refrigerant.
