Arefrigerator operating on the vapor-compression refrigeration cycle using refrige the refrigerant is considered. the temperature of the cooled space and the ambient a 13°c and 27°c, and leaves at 1 mpa and 70°c. the refrigerant leaves the condenser as saturated liquid. the rate of cooling provided by the system is 13 kw determine ir are at respectively. r-134a enters the compressor at 140 kpa as a saturated vapour a) the mass flow rate of r-134a and the cop b) the exergy destruction in each component of the cycle and the second law eficingy of the compressor, and c) the second law efficiency of the cycle and the total exergy destruction in the cycle
