The Ganzhou roof natural ventilation [sun] Dongguan roof, natural ventilation device 

 The roof of natural ventilation devices on the roof of the factory, very good ventilation. Often due to the operation of the machine tool factory and a hot and dirty smoke, according to the principle of thermal expansion and contraction, hot air will expand, so the number of air molecules within a certain volume less, the relative density of hot air will be compared with the cold air that is hot air is lighter than cold air, indoor hot air to rise, the indoor heat or pollution smoke gathered near the roof, so high, indoor temperature and pressure. At this time, as long as with natural ventilation in the roof, the indoor heat or pollution smoke would spin out of the diversion works of the law by the blade gap outdoor, indoor low pressure when the heat is out, the outdoor air is lower than the effect of pressure, so air will flow into indoor and fill the space of the heat to be drawn, and then to regulate the temperature, go decontamination smoke, indoor air becomes clean cool.
