泉福多层阳光板抗冷辐射

The excellent insulation properties of Quanfu sheet will also contribute to a reduction in the radiation of cold into the building. The lower the U-value, the higher the inner sheet surface temperature will be maintained during the winter season.
Fig. 9 presents an example of the temperature profile through 6 mm Quanfu  sheet
when the outside temperature is -10  C and the inside building temperature is +20  C.
卓越的绝缘性能使泉福多层板可以减少冷辐射进入建筑物。在冬季,U值越低,内部板材表面的温度维持得越高。

Comparison of Quanfu sheet with single glazed glass under the same conditions.
同等条件下泉福通用多层板和单层玻璃的对比
The multi-wall construction creates an air space which results in a moderate sheet surface temperature. Under the conditions indicated, the inner sheet surface temperature remains far above zero so that there is no cold radiation to the inside of the building
Fig. 10 compares Quanfu  sheet with single glazed glass under the same conditions. The inside glass surface temperature is well below zero, which means that cold radiation will negatively influence the overall building temperature and will affect the comfort level near the windows.
多层结构创造了一个产生适度板材表面温度的空气隔层。在此条件下,内部板材的表面保持着0 C以上的温度,所以没有冷辐射进入室内。
在相同条件下将泉福多层板和单层采光玻璃进行比较,玻璃内部表面温度在0 C以下,这就意味着冷辐射将消极影响整个建筑温度,并影响窗户附近的舒适度水平。
