Research on Indoor Thermal Environment Test of Membrane Building under Solar Radiation
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 greenhou-ses.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 ir-radiance,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.
