Refrigerant 134a enters the compressor of a vapor-compression refrigeration cycle at 150 kPa as a saturated vapor and leaves at 850 kPa. The refrigerant leaves the condenser as a saturated liquid. The rate of cooling provided by the system is 7kW. a. Determine the mass flow rate of R-134a and the cop of the cycle. b. If the condenser pressure is changed to 950 kPa, find the cop of the cycle.
