oper vapor compression refrigeration cycle. The evaporator and condenser pressures are 200 kPa and 1400 kPa, respectively. The isentropic efficiency of the compressor is 88 percent. The refrigerant enters the compressor at a rate of 0.025 kg/s superheated by 10.1°C and leaves the condenser subcooled by 4.4°C. Determine a) the rate of cooling provided by the evaporator, the power input, and the COP, b) the same parameters if the cycle operated on the ideal vapor-compression refrigeration cycle between the same pressure limits.

4. A refrigerator uses refrigerant-134a as the working fluid and operates on the vapor-
compression refrigeration cycle. The evaporator and condenser pressures are 200 kPa and
1400 kPa, respectively. The isentropic efficiency of the compressor is 88 percent. The
refrigerant enters the compressor at a rate of 0.025 kg/s superheated by 10.1°C and leaves
the condenser subcooled by 4.4°C. Determine
a) the rate of cooling provided by the evaporator, the power input, and the COP,
b) the same parameters if the cycle operated on the ideal vapor-compression refrigeration
cycle between the same pressure limits.
