摘　　要：针对适用于高层建筑和台风地区建筑的普通活动中置遮阳夏季得热偏高的问题,利用太阳热反射涂料,提高遮阳帘外表面反射比,通过增大百叶倾角或降低折叠帘透射比,提高遮阳帘遮蔽性能.进行了在模拟太阳光辐射下普通中置百叶及折叠帘遮阳、高反射高遮蔽中置百叶及折叠帘遮阳的得热对比试验,实测表明,提高反射比及遮蔽性能可明显降低得热量,夏季节能效果显著,综合遮阳系数能满足南方地区建筑节能标准要求。The high reflective and high shaded test-specimens were made by both using the paint which possessed the high capability of reflecting the solar heat and increasing the dip angle of the blinds or decreasing the transmittance of the foldable curtains in order to improve both of the reflectance and shaded capability on the external surface of the shading curtains for the higher heat-gaining problems happened in summer on the movable mid-shadings applied in the high-rise buildings and the buildings in the Typhoon frequently happening-regions. Through the comparative experiments about the gained heat on the normal midshadings （blind and foldable curtain）and the high reflective mid-shading （blind and foldable curtain） under the same condition of simulative solar irradiation,it was observed that the high reflective and high shaded test-specimens could reduce the gained heat obviously. The effect of energy conservation in summer was shown obviously,and the comprehensive shading coefficient can mainly meet those requirements of the standards for energy conservation in the southern China.
