Abstract This experimental model presents a method of reduce energy consumption and enhance the refrigerating effect. With the help of two phases condensing ejector it is found that ejector work as sub compressor in refrigeration flow cycle. That helps to reduce compressor load effectively and hence improve refrigerating effect. The new cycle includes a second step compression by an ejector device, the compressor compresses the vapour to approximately 4/5 of the final pressure and additional compression (i.e. 1/5 of final pressure) is provided in an ejector, the thermodynamic model has developed for R134 and R22 refrigerant showing a possible efficiency improvement as compared to the traditional vapour compression cycle. The investigation of a new cycle for vapour compression refrigeration with using a novel device for non-mechanical compression of refrigerants is called a condensing ejector has carried out within this project. This novel device is a hybrid of simple vapour compression refrigeration system [SVCRS] and ejector refrigeration system [ERS] is more attractive than traditional refrigeration system because of higher coefficient of performance [COP].That leads the energy saving for same amount of cooling.
Keywords Reciprocating Compressor, Two Phase Ejector, Condenser, Refrigerant Separator, Capillary, Drier, Evaporator, Pressure Gauge, Thermostat, Thermocouple and Refrigerant.
