Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. The primary principle of the selection of windows for natural ventilation ventilation chose livestock fan, selected model and the number of installed capacity to meet the requirements needed to ventilate the room, that meet the needs of the people in the room for the amount of fresh air. Windows and doors, curtain walls as natural ventilation windows and doors, curtain wall of a companion product, its structure and material terms of demanding, its wind pressure, anti-rain and noise insulation, air tightness and thermal performance requirements and doors match direct Livestock wet curtain fan, and you want to achieve with the doors and windows with life, choose the type of ventilation and the number of installations, to consider building their own combination of factors. First high livestock fan manufacturers, to consider the location of the climatic conditions of the building, such as the basic wind pressure and temperature conditions. Ventilation different pressure values ??on the same type and length of the obtained number of ventilators are different, to choose the type ventilators weatherproof performance indicators inform itself to meet the requirements. Temperature aspect to consider whether the cold regions, namely the type of ventilation through the K value and the possibility for the use of the U-value, in the cold season is not condensation. Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. 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 turbine company brand Livestock, ventilation long time; little effect precipitation, high moisture grain should be ventilated with axial fans. In order to cool down for the purpose of ventilation, the application of axial fans safe, efficient, energy-saving axial fans in the retarder Ventilation in precipitation for the purpose of ventilation.
