Question: Consider a refrigerator that operates on the vapor compression refrigeration cycle with R-134a as the working fluid. The refrigerant enters the compressor as saturated vapor

Consider a refrigerator that operates on the vapor compression refrigeration cycle with R-134a as the working fluid. The refrigerant enters the compressor as saturated vapor at 160 kPa, and exits at 800 kPa and 50oC, and leaves the condenser as saturated liquid at 800 kPa. The coefficient of performance of this refrigerator is
(a) 2.6
(b) 1.0
(c) 4.2
(d) 3.2
(e) 4.4
