Abstract
Ejector refrigeration system (ERS) is one of the major methods of refrigeration. It finds its maximum application in industries because it makes use of heat energy as input for refrigeration. ERS is also known as steam jet refrigeration because earlier only steam was used as working fluid. But latest developments offers make use of a variety of working fluids. Recent research results show that there is a large scope for improving efficiency and utility of the system with different working fluids. If suitable working fluid is selected, the ERS can make use of low temperature source like solar energy as input source. A large number of numerical and experimental works are actively going on in the field of ERS. The utilisation of computational fluid dynamics (CFD) software like ANSYS FLUENT has very much simplified the research activities of ERS. The effect of geometric design modifications of major components like nozzle or throat can be easily studied with the help of CFD software. This paper reviews the recent research and development in the area of ERS.
