建筑物的外围结构正日益被人们认为是一个动态的边界,而不是一个静态的屏障。它调节着室内外之间的能流,使购入的能量需要量减到最少程度。本文中所叙述的安装在室内紧靠窗户处的热百叶系统(见附图)展现了这种前景。它用未经制冷的水(77～85℉,甚至95℉)在中空的垂直百叶片中循环,夏季时控制太阳辐射得热量,冬天时控制传热损失。冷风系统是不能阻止太阳辐射能进入房间内的,除非用实物遮档,否则辐射热便进入房间被人和物体吸收。之后,只能用较多的冷风才能消除该热量,但是,在此过程中人们常常要备受既有辐射
The peripheral structure of a building is increasingly considered as a dynamic boundary rather than a static barrier. It regulates the energy flow between indoor and outdoor and minimizes the amount of energy required for purchase. The hot louver system (see attached figure) installed close to the window in the room described in this article demonstrates this prospect. It uses uncooled water (77-85°F, or even 95°F) to circulate in hollow, vertical louvers. In summer, solar radiation controls heat gain, and in winter it controls heat loss. The cold air system cannot prevent solar radiation from entering the room. Unless it is covered with physical objects, radiant heat enters the room and is absorbed by people and objects. After that, only a lot of cold air is needed to eliminate this heat, but in the process people often have to suffer from existing radiation.
