What are the exhaust fan installation requirements?

​The exhaust fan can quickly discharge the hot indoor air, and suck the air on the other side of the outdoor into the room, so that the temperature is equal to the outside temperature, and the temperature in the workshop will not rise. In the process of air flow, the body heat will be taken away, and the air flow will accelerate the evaporation of sweat and absorb the body heat, thus making the body feel cool and as cool as the natural wind.
