Question

A refrigerator uses R-134a as the working fluid and operates on the vapor-compression refrigeration cycle. The evaporator and condensor pressures are 200kpa and 1400kpa, respectively. The isentropic efficiency of the compressor is 88%. The refrigerant enters the compressor at a rate of .025 kg/s superheated by 10.1 degrees C and leaves the condensor supercooled by 4.4 degrees C. Determine (a) the rate of cooling provided by the evaporator, the power input, and the COP.
This problem is 11-26 in Thermoldynamics, an engineering approach (7th) ed by Cengal.
