[0002] Roof ventilators are a mainstream type of ventilators widely used in various public buildings and steel structure workshops. They consume no power and are easy to maintain. According to their appearance and ventilation volume, they are divided into ball ventilators and strip ventilators. Their work is based on the characteristics of hot air gathering upwards and the principle of fluid thermodynamics. With the difference in air pressure and temperature between indoor and outdoor, supplemented by natural wind, the ventilator automatically operates in a natural state to maintain a natural ventilation state.
