Experimental Investigation and Performance of Vortex Tube Refrigeration

Dr. Ajoy Kumar

Abstract: The simultaneous release of hot air at one end & the cold air at the other end of the same tube by using compressed air, made the Pulse tube refrigeration system very interesting. After proper design and fabrication, the present vortex tube is tested in the laboratory by providing compressed air from a reciprocating air compressor having specification of FAD=13.608 m3/hr. Co-efficient of performance, (c. o. p. ) and Adiabatic efficiency, (adia) have been achieved as 0.1075 and 10.75 %. Moreover, temperature of coldest and hottest air were recorded as -6 0C and 630C respectively.
