摘　　要：搭建膜建筑室内热环境测试平台,在不同太阳辐照度、室外温度条件下(夏季晴天日、夏季阴天日、冬季晴天日),测试膜建筑室内温度及屋顶内外表面温度的变化。对于室内温度:在白天太阳辐照度比较大时,太阳辐照度的影响占主导,膜建筑室内热环境类似日光温室。在阴天太阳辐照度比较小以及夜间时,室外温度的影响占主导。对于屋顶内外表面温度:对于夏季晴天日,白天屋顶内外表面温度变化趋势均与太阳辐照度变化趋势基本一致,且外表面温度高于内表面温度。夜间太阳辐射作用消失,屋顶内外表面温度均下降,且趋于接近。夏季阴天日、冬季晴天日,屋顶内外表面温度变化情况与夏季晴天日相似。An indoor thermal environment test platform for membrane buildings was built to test the changes in indoor temperature of membrane buildings and the temperature of the inner and outer surfaces of the roof under different solar irradiance and outdoor temperature conditions(sunny days in summer,cloudy days in summer and sunny days in winter).For indoor temperature:when the solar irradiance is relatively strong during the day,the influence of solar irradiance dominates,and the indoor thermal environment of the membrane building is similar to that of solar greenhouses.On cloudy days with weak solar irradiance and at night,the influence of outdoor temperature dominates.For the temperature of the inner and outer surfaces of the roof:for sunny days in summer:the temperature trend of the inner and outer surfaces of the roof during the day is basically consistent with the trend of solar irradiance,and the temperature of the outer surface is higher than the temperature of the inner surface.At night,the solar radiation disappears,and the temperature of the inner and outer surfaces of the roof drops and tends to be close.On cloudy days in summer and sunny days in winter,the temperature changes on the inner and outer surfaces of the roof are similar to those on sunny days in summer.
