围护结构隔热对室内热稳定及空调负荷的影响

The Effects of Thermal Insulation Form on Thermal Stability and the Cooling Load of Air Conditioning

建筑围护结构不单是隔热体,也是一个有着蓄热功能的被动热源体。因此,当隔热层的位置或主体结构的材质不同时,其对室内空气的热作用效果是不同的。本文引入了围护结构的"热稳定性度时数(DH)"和"反应系数(BER)"的概念,分析了不同形式的围护结构对室内空调冷负荷及室内空气热稳定性的影响。研究结论对如何针对不同的使用条件下合理选择围护结构的隔热形式有参考意义。

Building envelops act not only as a heat-transfer resistance, but also as a passive heating source. When the position of the heat insulation layer or the material of envelops is different, the effectson indoor air will be different.The influence of the building envelops on indoor thermal comfort and cooling load of air conditioning was presented by two introduced factors: thermal comfort degree-hour(DH) and building envelope response factor(BER). The developed result may be a referrence for selecting insulation form of the building envelops in different application cases.
