Air Refrigeration System by Using Vortex Tube

Abstract Vortex tube is a mechanical device with no moving parts in it. When compressed air is sent into it results in producing two air streams of extreme temperatures. This special characteristic of vortex tube is used for different purposes like heating and cooling. Vortex tube produces both cold and hot air from its both ends simultaneously. In this paper, the main focus on the cold end temperatures because of which refrigeration effect is produced. Four different vortex tubes with different dimensions, number of nozzles, orifice & Venturi are fabricated and their COP's are compared.
