5. The refrigeration system shown below is another variation of the basic vapor compression refrigeration system which attempts to reduce the compression work. In this system, a heat exchanger is used to superheat the vapor entering the compressor while sub-cooling the liquid exiting from the condenser Consider a system of this type that uses refrigerant-134a as its refrigerant and operates the evaporator at -10°C, and the...
