| 摘要: |
| 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之间，出风角度在30°~45°之间时，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。 |

| Abstract: |
| Moisture condensation appears on enclosure structure especially on the inner face of glass curtain walls due to high humidity and high temperature. Through analysis of condensation on the envelope surface with high temperature and high humidity by field measurement and combination of theoretical calculation and numerical simulation, the distance between the air vent and curtain wall and the outlet angle of the supply air are concluded as key influential factors. When the distance ranges from 0.2 m to 1.1 m and the outlet angle is between 30° to 45°, large area of condensation on glass curtain wall could almost be avoided; when the outlet angle of the supply air is 16°, the larger the distance between the air vent and curtain wall is, the less the condensation on envelope structure will be; while the outlet angle of the supply air is more than 45°, the less the distance between the air vent and exterior wall is, the less condensation will appear . |
