AF1喷嘴是一种气水雾化加湿喷嘴,它具有雾场均匀、不易堵塞、不会漏水等优点,既可用在一些特殊的无中央空调的工作环境中,又可对有中央空调的环境进行补充加湿.对该类喷嘴的结构及雾化特性进行研究,以推进该类喷嘴的国产化进程,指导其应用,具有重要的现实意义.本文以压缩空气、水为工质,使用三维LDV/APV系统对该喷嘴的雾化特性进行了实验研究,测量了不同水、气压力条件下,雾场颗粒的粒径和三维速度,讨论了相关参数改变后,对喷嘴雾化效果的影响.

AF1 nozzle is used for water atomization, which can increase air humidity.Its virtues include uniform spray,never be jammed,leak-free etc.we can use it for increase air humidity both in the environment of center air-conditioning and other special indoor location.It has important significance to study its structure and characteristics of atomization.In This paper the characteristics of atomization of AF1 nozzle are investigated.The diameter and 3D speed of the particle is measured by 3D LDV/APV system under different hydraulic pressure and air pressure and water and compress air as working medium.Iy is disscussed that the working conditions have the effects on the nozzle's atomization.
