The figure shows a two-stage, vapor-compression refrigeration system with two evaporators and a direct contact heat exchanger. Saturated vapor ammonia from evaporator 1 enters compressor 1 at 12 lbf/in² and exits the compressor at 46 lbf/in². Evaporator 2 operates at 46 lbf/in2, with saturated vapor exiting at state 8. The condenser pressure is 200 lbf/in2, and saturated liquid refrigerant exits the condenser. Each compressor stage has an isentropic efficiency of 80%. The refrigeration capacity of each evaporator is shown on the figure. Step 1 -5 Expansion A valve +6 -7 Evaporator Expansion valve Qout Condenser Compressor 2 Qin,2 = 10 tons 8 Evaporator Compressor Direct contact heat exchanger in,1 = 5 tons W₁₂
