鲁西南荷泽地区防空洞很多,其结构不一,大致有三种类型:一、水泥结构,洞内各房间设有采光窗。因有采光窗,大地气温对洞内温度有影响,冬季温度17℃—18℃,夏季温度21℃—22℃。二、水泥结构,洞内各房间设有鼓风筒,没有采光窗。因没有采光窗,洞内温度受大气温度影响很小,洞内 Southwest Heze large area air defense shelters, the structure is different, there are roughly three types: First, the cement structure, the cave has a room with light windows. Because of the light window, the temperature of the earth has an impact on the temperature in the cave, the winter temperature of 17 ℃ -18 ℃, the summer temperature of 21 ℃ -22 ℃. Second, the cement structure, each room with a hairdryer tube, no light window. Because there is no light window, the temperature in the hole is very small, the inside of the hole is affected by the atmospheric temperature
