室内冰场湿空气状态的实验研究

Experimental Study on Fogging of Indoor Ice Rink

在冰场的运行过程中,由于冰面附近空气与室内空气不断混合,湿空气状态极有可能处于雾区,产生起雾现象,对冰场的使用产生不利影响。本文通过实验测量在不同送风状态下,冰场内部的温湿度分布情况,同时对送回风状态和冰场温湿度分布结果进行分析。结果显示送风状态在较低的相对湿度下(30%~40%)能够极大地削弱起雾现象发生的可能,上送下回的送风方式是冰场最为合理的送风方式,且回风口的高度越低越好。

In the operation process of the ice rink,due to the continuous mixing of air near the ice surface and indoor air,wet air is very likely to be in the fog area,resulting in fog phenomenon,which has adverse effects on the use of the ice rink.In this paper,the temperature and humidity distribution in the ice rink is measured by experiment with different air supply conditions,and the results of temperature and humidity distribution in the ice rink are analyzed.The results show that the possibility of fogging can be greatly weakened under the condition of low relative humidity(30%-40%).The air supply mode with the upper supplyment and lower return is the most reasonable for ice rink,for the better earnings as the lower of the height of the air return port.
