Chapter 11, Problem 116P(choose chapter or problem)
11-116 A two-stage compression refrigeration system with an adiabatic liquid-vapor separation unit as shown in Fig. P11-116 uses refrigerant-134a as the working fluid. The system operates the evaporator at \(-32^{\circ} \mathrm{C}\), the condenser at , and the separator at \(8.9^{\circ} \mathrm{C}\). The refrigerant is circulated through the condenser at a rate of
\(2 \mathrm{~kg} / \mathrm{s}\). Determine the rate of cooling and power requirement for this system. The refrigerant is saturated liquid at the inlet of each expansion valve and saturated vapor at the inlet of each compressor, and the compressors are isentropic.
