Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. "Roof natural ventilation selection and installation of the" national standard atlas 1. Scope: This portfolio is suitable for large-scale industrial plants and civil tall space economically rational use of natural ventilation in place, and should take full account of local outdoor weather conditions. 2, natural ventilation type: includes streamlined roof natural ventilation and natural ventilation roof cyclone type two kinds. Does not include all types of roof exhaust hood. Streamlined roof natural ventilation is installed on the roof, the use of heat and pressure to form the indoor and outdoor temperature reaches the replacement of indoor air devices. In between the boiler, turbine and so have a lot of heat between the workshop used this device. Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. The role of mechanical ventilation axial fans in the grain temperature due to the temperature difference between the larger and the first time to choose the ventilation during the day, in order to reduce the gap between food mild temperatures, reduce condensation occurs. After ventilation as much as possible at night, because this is a cool airy main evening relatively high atmospheric humidity, low temperature without power ventilation, so that reduces moisture loss, but also take advantage of the low temperatures at night, improve the cooling effect. When retarder ventilation axial fans, axial fans due to the small amount of wind, in addition to food is a poor conductor of heat, ventilation prone to individual parts of the initial slow ventilation without power ventilators offer, along with the continuation of the whole warehouse ventilation grain temperature will gradually balance. Slow food carried ventilation must be vibration sieve cleaning, and food into the impurity regions must be promptly cleaned compartment automatic grading caused no power ventilators price, otherwise easily lead to uneven local exhaust ventilation. 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. Disadvantages: Due to the small amount of wind, a long time ventilation; ineffective precipitation, high moisture grain should be ventilated with axial fans. No power ventilation accessories, Flextronics ventilators (certified), Zaozhuang without power ventilators from Liaocheng Flextronics ventilation equipment Limited.
