Advantages to conduct retarder axial fan ventilation: cooling effect is good; low energy consumption, is particularly important in promoting energy today; ventilation and easy to grasp the opportunity, less prone to condensation; not alone with fans, convenient and flexible. Cons: Because of the small amount of wind axial fan, ventilation long time; precipitation ineffective small pipe axial fans, high moisture grain should not use axial fan for ventilation. Advantages centrifugal fan: cooling, precipitation effect is obvious best axial fan, ventilation time is short; Disadvantages: high energy consumption; ventilation timing was bad prone to condensation. Conclusion: In order to cool down for the purpose of ventilation in the axial fan manufacturers, application axial fans safe, efficient, energy-efficient ventilation retarder; centrifugal fan application in order for the purpose of ventilation in precipitation. Axial fans must be divided into imports under test port or outlet pipe to increase the exit of any additional aid under, but at the exit cone with auxiliary supply axial fans, etc. out with the exception of imports, in order to have the B-type exit at the conditions should be rectified into an outlet duct gate, when axial fan safety net without any conditions, use duct is divided into sections. Axial fans must be imported without any auxiliary equipment testing, with the axial fan unit should be supplied with a pipeline capable of acceptance only after it has carried out into whether safety.
