Experimental Investigation on the Performance of Vortex Tube
Non-conventional systems are developed to produce cooling effect which use eco-friendly refrigerants and consuming less energy as input. In this work, a vortex tube refrigerator is fabricated from CPVC material, to which air is supplied through five tangential inlet nozzles at different inlet pressures. The inlet pressure is varied over a span of 1 kg/cm2 to 8 kg/cm2 with an interval of 1 kg/cm2. The difference between the temperatures of hot and cold air streams at outlet is observed to be increasing with time as well as for different inlet pressures. In addition the COP for the cold end side is observed to be more than at the hot end side and isentropic efficiency is observed to be increasing with inlet pressures.
