某些室内环境因空气温度高湿度大,造成外围护结构尤其是玻璃幕墙内表面结露。通过采用现场实测、理论计算和数值模拟相结合的方法对高温高湿室内围护结构表面结露进行分析,发现空调送风口与幕墙之间的距离与送风口的出风角度是主要影响因素。当风口与玻璃幕墙间距在0.2~1.1 m,出风角度在30°~45°时,基本可避免玻璃幕墙上出现大面积结露;出风角度为16°时,风口与外墙的间距越大,越有利于避免外围护结构结露;出风角度大于45°时,风口与外墙的间距越小,结露区域面积越小。
Some indoor environment due to high temperature and humidity of the air, resulting in the outer envelope structure, especially the inner surface of the glass curtain wall condensation. Through the combination of field measurement, theoretical calculation and numerical simulation, the dew condensation on the surface of high-temperature and high-humidity indoor envelope was analyzed. It was found that the distance between the air-conditioner outlet and the curtain wall and the outlet angle of the outlet were the main influencing factors. When the air outlet and the glass curtain wall at a distance of 0.2 ~ 1.1 m, the air outlet angle of 30 ° ~ 45 °, the basic glass curtain wall can be avoided on a large area of condensation; outlet angle of 16 °, the outlet and the distance between the outer wall Large, the more conducive to avoid condensation of the outer envelope; When the air outlet angle is greater than 45 °, the smaller the gap between the outlet and the outer wall, the smaller the area of condensation.
