La figura muestra un sistema de refrigeración por compresión de vapor de dos etapas con dos evaporadores y un intercambiador de calor de contacto directo. El vapor saturado de amoníaco del evaporador 1 entra, en el compresor 1 a 18 \( \mathrm{lbf} / \) pulg \( ^{2} \) y sale a \( 70 \mathrm{lbf} / \) pulg \( ^{2} \). El evaporador 2 funciona a \( 70 \mathrm{lbf} / \mathrm{pulg}^{2} \) y el vapor saturado sale en el estado 8. La presión del condensador es de \( 200 \mathrm{lbf} / \mathrm{in}^{2} \), y el refrigerante líquido saturado sale del condensador. Cada etapa del compresor tiene una eficiencia isoentrópica del 80\%. Dibuje el diagrama T-s del ciclo y determine: (a) Las temperaturas, en \( { }^{\circ} \mathrm{F} \), del refrigerante en cada evaporador. (b) La potencia de entrada a cada etapa del compresor en KW c) \( \mathrm{El} \beta \)

A two-stage compression refrigeration system with an adiabatic liquid-vapor separation unit as shown in Fig. P1 $1-116$ uses refrigerant-134a as the working fluid. The system operates the evaporator at $-32^{\circ} \mathrm{C}$, the condenser at $1400 \mathrm{kPa}$, and the separator at $8.9^{\circ} \mathrm{C} .$ The refrigerant is circulated through the condenser at a rate of 2 kg/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.
A two-stage compression refrigeration system with an adiabatic liquid-vapor separation unit like that in Fig. $\mathrm{P} 11-60$ uses refrigerant- $134 \mathrm{a}$ as the working fluid. The system operates the evaporator at 60 psia, the condenser at 300 psia, and the separator at 120 psia. The compressors use $25 \mathrm{~kW}$ of power. Determine the rate of cooling provided by the evaporator and the COP of this cycle. 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.
