The technology is proliferating and making our environment unwell for existence, by emission of hazardous elements that causes depletion of ozone layer and affect the human comfort. The objective of the dissertation is to study the concept of vortex tube that can be used for refrigeration purpose and in future can be the best replacement over conventional refrigeration systems. This paper reviews the research to enhance the refrigeration effect by changing nozzle geometry, changing the geometry of the cylindrical tube in to conical tube at various cone angles, installing a diffuser between the vortex tube outlet and hot valve and the reason of energy separation within the vortex tube.
