Résumé

A vapor jet refrigeration system (VJRS) is an alternative to the conventional mechanically driven vapor-compression refrigeration system. The VJRS utilizes supersonic ejector as thermal compressor and has the potential to reduce energy consumption and utilize low grade energy for driving the refrigeration systems. In the present study, the performance characteristics of VJRS ejectors with R134a as refrigerant have been investigated numerically using commercial CFD software. For the numerical simulations on the selected ejector, generator temperature is varied from 55°C to 80°C, the condenser temperature is varied from 20°C to 35°C, and the evaporator temperature is varied from -10°C to 10°C. The numerical results obtained contribute to understanding the local structure of the flow. Moreover, the results help in identifying the optimum operating condition for each value of ejector area ratio.
