A Review of Vortex Tube Refrigeration System

Abstract

In developing countries refrigeration plays an important role, firstly for food preservation, storage of medicines, and as air conditioning in homes, offices, etc. Freon is used as a refrigerant in conventional refrigerators. Freon is a harmful chemical to the environment and helps depleting of ozone layer. And hence scientists are trying to find alternative methods of refrigeration. Vortex tube is a cooling device which is non-conventional and since it has no moving parts it is much more efficient. A vortex tube has a hot end and a cold end from which hot air and cold air is produced respectively with compressed air as its source. And due to this it has no harmful effect on the environment. When high pressure air is entered tangentially inside the vortex chamber a vortex flow is generated which is split into two flows, one is hot air flow and the other is the cold air flow. Considering the harmful effects on the environment due to conventional refrigeration methods there is a need to find such non-conventional techniques for the betterment of the environment.
