Summary:Conventional vapour compression systems prove to be expensive for continual, specialized usage and require maintenance as there are several moving parts. A vortex tube cooling system has no moving parts and operates as a small cooling machine by separating the compressed gas into two different streams namely cold and hot streams. The thermal performance of the system was studied as function of a geometrical parameter i.e. L/D ratio of the vortex chamber, under various inlet pressure conditions. The study was oriented towards obtaining the maximum possible temperature drop across the system. Experiments were carried out by varying the L/D ratio and an inference was drawn on the cold fraction. Results proved that the length to diameter ratio plays an important role in the performance of the vortex tube cooling system.
