Action fans and centrifugal fans in mechanical ventilation in a 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 square axial fans, the evening relatively high atmospheric humidity, temperature lower sidewall axial fan, so that reduces moisture loss axial fans, also take advantage of the low temperature at night axial fans t35, improve the cooling effect.
