Through specific engineering design, and designing the ventilation speed and wind speed as required, any high heat, harmful gas, dust and smoke can be quickly discharged from the workshop, and any poor ventilation problems can be completely solved at one time. Ventilation can be achieved within seconds of turning on the fan.
How to arrange comprehensively?
First, the fan should be installed on the side wall or gable on the downwind side of the greenhouse. If the fan must be installed on the upwind side, the total design ventilation flow should be increased by at least 10 writes.
The second is that the distance between the fan exhaust port and adjacent obstacles (such as the wall of a building) should be greater than 1.5 times the diameter of the fan impeller.
Third, when designing the number of fans G3, it is recommended that more than one of them be driven by a two-speed motor in order to adjust the ventilation flow more conveniently and flexibly.
Fourth, there should be shutters on the outside of the fan to prevent air from flowing backwards or pests and dirt from invading when the machine is stopped.
The development of ventilation and cooling projects
in our country has been paid more and more attention.
