What is the smoke exhaust method of gas-fired building with roof ventilation? How to control ventilation?

Natural ventilation is the smoke exhaust method for gas-fired buildings with roof ventilation. Industrial enterprises usually customize and install gas buildings with natural ventilation on the roof to meet the needs of workshop ventilation and lighting in the process of production and operation. The roof ventilation building installed in the factory building is also called natural ventilator or ventilation skylight, which uses the temperature difference effect between indoor and outdoor to form natural airflow, thus meeting the requirements of indoor ventilation. The gas-fired building with natural ventilation on the roof does not need electricity and electricity consumption, and does not need frequent maintenance after installation and use, which can give consideration to ventilation and lighting and save expenses for enterprises.

Roof ventilation buildings are controlled by installing opening and closing valve plates or ventilation partitions (natural ventilation is equivalent to the function of windows). Simply put, it is the window in the ventilation window. Characterized in that one side of the window frame is provided with a ventilation duct, and the ventilation duct of the window frame is internally provided with a heat transfer baffle which divides the ventilation duct of the window frame into an air inlet duct and an air outlet duct which are arranged adjacently. The upper part of the window frame ventilation duct is provided with an indoor air inlet and an indoor air outlet staggered by 90 degrees, and the lower part is provided with an outdoor air inlet and an outdoor air outlet staggered by 90 degrees. The heat transfer partition can be made of aluminum plate. A coarse filter screen and a check valve can be arranged in the air inlet duct and the air outlet duct. Indoor ventilation can be realized without opening the window sash, which reduces the indoor heat loss during ventilation and can save energy.
