Determine the mass flow rate of r-134a and the cop

Reference no: EM13564916

A refrigerator operating on the vapor-compression refrigeration cycle using refrigerant-134a as the refrigerant is considered. The temperature of the cooled space and the ambient air are at 108F and 808F, respectively. R-134a enters the compressor at 20 psia as a saturated vapor and leaves at 140 psia and 1608F. The refrigerant leaves the condenser as a saturated liquid. The rate of cooling provided by the system is 45,000 Btu/h. Determine

(a) the mass flow rate of R-134a and the COP,

(b) the exergy destruction in each component of the cycle and the secondlaw efficiency of the compressor, and
