热压与风压二者都是作用于建筑物上,从而造成空气渗入和渗出的因素。对于建筑物的某个部位或房间来说,热压的大小随内部和外部空气的容重差而变化,而风压的大小和正负则随风力和风向而变化。二者之间并不存在什么比例之类的直按关系。这尤如计算夏季通过玻璃窗的得热量中包含因室内外温差而造成的传热量与因太阳辐射而造成的辐射热量,二者之间不存在直接关系一样。在建筑物的同一高度上,作用于各朝向房间围护结构上的热压都相等,它和各朝向的风力、频率等因素是没有关系的。有的同志提出,在同一高度上各朝向的热压与其风的某个系数(由风速和频率确定)成正
Hot pressure and wind pressure are both factors that act on the building, causing air infiltration and exudation. For a certain part of a building or a room, the size of the hot pressure varies with the difference in the internal and external air weight, and the magnitude and the positive and negative wind pressure change with the wind force and the wind direction. There is no straightforward relationship between the two. This is similar to the calculation of the amount of heat generated by the temperature difference between indoor and outdoor and the radiant heat caused by solar radiation in the calculation of the amount of heat that passes through the window in the summer. There is no direct relationship between the two. At the same height of the building, the thermal pressure acting on the enclosure structure of each facing room is equal, and it has nothing to do with the wind force, frequency, etc. of each direction. Some comrades suggested that the hot pressure of each orientation at the same height is a positive coefficient (determined by the wind speed and frequency) of the wind.
