Due to the global warming, the number of days of high temperature in summer continues, and the intensity of light compression is high. There are many small and medium-sized production lines around us. In summer, we just started to find a cooling method for factory workshops, but we didn't find a suitable one. In the production workshop, the staff only use the industrial production fan to deal with the temperature reduction. However, the staff are still sweating in their respective positions. For a long time, when the temperature is higher than all the normal areas, it is very easy to have the situation of China deployment. In the high temperature natural environment, people can not concentrate on the spiritual essence, leading to low spirits, which is very easy to make mistakes and lead to unnecessary damage.
