Abstract
The Vortex Tubes are broadly using in spot cooling applications such as less noise, space, and equipment costs are primary factors. In this experiment, two vortex tubes were used, and these two are hot cascade type vortex tube. Performance of hot cascade type vortex tube investigated experimentally at different inlet pressure, number of nozzles, and L/D ratios (10, 15, & 20). Based on the temperature difference between hot outlet 1 and inlet (ΔThot1.), hot outlet 2 and hot outlet 1 (ΔThot2), cold outlet 1 and inlet (ΔTcold1), cold outlet 2 and hot outlet 1 (ΔTcold2) performance were analyzed. Coefficient of Performance (COP) investigated using experimental data. The COPc1 = 0.0203, COPh1 = 0.01884, COPc2 = 0.163, and COPh2 = 0.01893 at temperature differences ΔTcold1 = 8.2°C, ΔThot1 = 7.4°C, ΔTcold2 = 26.3°C, and ΔThot2 = 17.2°C are obtained better values at L/D = 15, Pi=10 bar and N = 5 combination.
