A vapor-compression cycle refrigerator using R-22 as the working fluid has an evaporator temperature of -30.0°C and a condenser temperature of 50.0°C.
The refrigerant enters the compressor at 7.50 kg/min as a saturated vapor and exits the condenser as a saturated liquid. The isentropic efficiency of the compressor is 82.5%. Determine
a. The coefficient of performance for the system.
b. The coefficient of performance for a reversed Carnot cycle with the same temperature limits.
c. The refrigeration (in tons) that this system can provide.
