EXPERIMENTAL STUDY ON COOLING SYSTEM OF SMALL FLOW VORTEX TUBE WITH HUMIDIFIER AT THE HOT END

本文针对一种小流量涡流管加湿制冷系统进行了实验研究,得出了涡流管制冷系统不同入口压力下无加湿系统和有加湿系统的绝热效率曲线,指出需要解决的关键技术问题。实验表明,有加湿系统可以大大提高涡流管的绝热效率。

Experimental study on a cooling system of a small flow vortex tube with the humidifier at the hot end is described in the paper. Experimental adiabatic efficiency curves, which are in the two conditions of vortex cooling system and vortex cooling system with humidifer, have been found in diferent entrance pressure condition. The problems of key technology to be solved are discussed. The conclusion is that the system using humidifier can greatly improve the adiabatic efficiency.
