An improved refrigeration system with a heat exchanger is shown in the following picture. The heat exchanger is used to superheat the vapor entering the compressor while subcooling the liquid leaving the condenser. The system uses R-134a.

The heat exchanger provides 40oF of subcooling at the throttle valve entrance. a) Calculate the entropy generation at the throttle for the simple refrigeration cycle. Calculate also the entropy generation of the universe (throttle + surroundings) due to this operation. b) Calculate the process efficiency of the heat exchanger for the refrigeration cycle that includes the heat exchanger
