普通办公楼、住宅等建筑物屋顶常用架空隔热板进行隔热。这种隔热层一方面可以遮挡直射阳光,另一方面架空层内被加热的空气与外部冷空气产生对流,可将透射架空层内的大部分热量带走,如此循环不已,达到隔热降温目的。因此,架空隔热板内空气能否畅流是降温的关键,而决定空气... Ordinary office buildings, residential buildings and other buildings commonly used overhead insulation board insulation. On the one hand, this kind of heat insulation layer can block direct sunlight, and on the other hand, the heated air in the overhead layer is convected with the external cold air, and most of the heat in the transmissive overhead layer can be taken away. This cycle is endless to achieve thermal insulation and cooling. purpose. Therefore, whether or not the air in the overhead heat insulation board can flow smoothly is the key to cooling down, and the air is decided...
