Especially in most parts of our country, the summer climate is hot, and the internal temperature of large factories is high under high temperature, which makes some machines with high temperature requirements affected in use. Similarly, when the temperature of some large grain depots is too high, it will cause moldy grains, which will cause serious economic losses. When the daytime temperature difference is large, the external environmental factors directly affect whether the factory building needs to open and close the windows. When people rest at night, they cannot timely control the windows according to the temperature, humidity and rainfall. And in most factory buildings, the windows are relatively high, so it is very inconvenient to switch them manually, and the operation of opening and closing windows is relatively dangerous. the
