为了解决某地下景观观赏玻璃内表面的结露问题,本文设计了1个通风除湿系统,由风机引入环境空气,并及时排除内部的湿负荷,防止玻璃内表面产生结露现象。应用CFD软件对该通风除湿设计进行了气流组织模拟,结果表明在设计工况下,通风30 min后,玻璃下方空气的相对湿度明显降低;通风2 h后,内部湿度场接近稳定状态,整个空间内湿度均比较低,内部空气的露点温度比玻璃内表面温度低4℃,说明该通风设计可以很好地防止结露现象的产生。
In order to solve the problem of condensation on the inner surface of an ornamental glass in an underground landscape, a ventilation and dehumidification system is designed in this paper. The introduction of ambient air by the fan and timely elimination of the internal wet load prevent condensation on the inner surface of the glass. The CFD software was used to simulate the airflow dehumidification design. The results showed that the relative humidity of the air under the glass decreased significantly after 30 min of ventilation under design conditions; after 2 h of ventilation, the internal humidity field was close to the steady state and the entire space Within the humidity is relatively low, the dew point of the interior air temperature is lower than the inner surface of the glass 4 ℃, indicating that the ventilation design can be very good to prevent the phenomenon of condensation.
