室内滑冰场温湿度分布与产雾关系的研究

Study on the relationship between the humiture and the fog in indoor ice rink

通过数值模拟和实验的方法,分析了室内滑冰场上部送风下部回风,回风口位于0.3m、0.8m、1.5m(即不同回风高度)时室内温湿度场分布的规律。研究得出,回风口处于0.3m时房间内各个点的温度比回风口处于0.8m时相同位置各个点的温度要高,回风口处于0.8m时房间内各个点的温度比回风口处于1.5m时相同位置各个点的温度要高。通过对照焓湿图得出,回风口设置在0.3m时,能消除室内滑冰场出现雾气的现象。

Through the methods of numerical simulation and experiment, this essay analyzed the rule of indoor temperature and humidity field distribution in an ice - rink, where blowing - in on the top and return air on the bottom, in which the return air inlet located at 0.3m, 0.8m and 1.5m （which means different return air height）. According to the research, when the inlet was at 0.3m, the temperature of the same point was higher than one when at 0.8m. When at 0.8, the temperature of the same point was higher than one when at 1.5m. Contrasting with the psychrometric chart, it was found that the phenomenon of fog in the ice - rink could be eliminated when the inlet was at 0.3m.
