旋转可调式百叶窗的实验测试分析研究

遮阳百叶窗是实现建筑节能的有效措施之一。针对现有百叶窗的局限性进行改进，设计出一种能够更好兼顾遮阳和通风的旋转可调式新型百叶窗，通过与传统百叶窗的对比实验测试，分析得到了新型百叶窗对室内太阳辐射量和通风量的影响。实验测试表明，控制一定的通风量时，采用旋转可调式百叶窗其室内辐射得热量最大可减小75％；控制一定的辐射量时，采用旋转可调式百叶窗室内通风量可比传统百叶窗增加30％以上。综合分析表明，旋转可调式百叶窗对于减少室内太阳辐射，增大室内通风量效果显著。

The Experiment Test and Analysis Research for Rotary Adjustable Blinds

Window-blinds system is one of the effective measures for building energy efficiency. In the light of the limitation of the existing blinds, designed a new rotary adjustable blinds system, which is able to balance shading and ventilation better. From the contrast experiment on the new blinds and the traditional one, analyze the effects of new blinds on indoor solar radiation and ventilation rate. Experimental results show that, controlling a certain rate of ventilation, the indoor radiation heat gain can be decreased by 75% when using the rotary adjustable blinds; controlling a certain amount of radiation, the ventilation quantity can reach more than 30% of traditional blinds. Comprehensive analysis shows that, to reduce indoor solar radiation and increase indoor ventilation, the effect of new rotary adjustable blinds is remarkable.
