Vortex tube is the device that can separate small particles from the compressed gas, as well as compressed gas into hot and cold flow. Energy separation ability of vortex tube has been studied to investigate the possibility of the vortex tube as a substitute for an HVAC system of automobile. Experimental equipment has been made to obtain fundamental design parameters, energy separation characteristics has been analyzed for various supply pressure conditions. As increasing supply pressure, energy separation effect increased. Maximum temperature exists near 0.9 of the cold-out-flow-ratio, and minimum exists near 0.4. Based on the experimental results, the vortex tube for HVAC system of Electric Vehicle was redesigned. Also, detailed design is being processed to meet the air-volume of a commercial HVAC system.
