Abstract— In present, the first and foremost important quality of any research or development is its eco-friendly nature, by the virtue of which it fulfils our basic needs without any harm to the nature. Today, environment safety has become an important aspect of the industries and people in common. This paper aims at increase in efficiency of one such eco-friendly system named vortex tube used for industrial spot cooling and process cooling needs, such as Spot cooling, Weld cooling, Plastic slitting, Extrusion cooling, Foodstuffs cooling etc. The commonly used cooling systems use the gas and liquids which either deplete the ozone layer or contribute in the global warming in the same as CO2 does. Efforts have been made to include various aspects to get the maximum output in terms of C.O.P. (COEFICIENT OF PERFORMANCE) and knowledge about the vortex tube. The report includes detailed explanation of working and construction of a vortex tube with experimental results for a series of different physical, thermal and mechanical conditions. This paper summarizes analysis of cooling and heating effect, temperature difference and C.O.P. with different working conditions and constructional features. This paper also has the tabulated data with experimental values.
