A very large, two-stage, vapor-compression refrigeration unit using R-134a produces 3000 tons of refrigeration with an evaporator pressure of 100 kPa and a condenser pressure of 2000 kPa. The intermediate flash chamber operates at 800 kPa, and the isentropic efficiencies of the compressors in each loop are both 91%. The following operating specifications have been determined for the stages (loops):
Stage (Loop) A
Stage (Loop) B
For this design, determine
a. The mass flow rate of the refrigerant.
b. The system's coefficient of performance.
c. The total power required by the compressor.
