Air pipe type ventilation device used for factory building

Abstract

The invention relates to an air pipe type ventilation device used for a factory building. The air pipe type ventilation device comprises a main air supply pipeline and is characterized in that an auxiliary air supply pipeline is connected with the main air supply pipeline through an air guide pipeline, and the auxiliary air supply pipeline is connected with an auxiliary return air pipeline through a connection control device. Meanwhile, a main return air pipeline is connected to the auxiliary air supply pipeline through an air guide pipeline, and an air guide assembly is arranged on each air guide pipeline. In this way, an interactive air supply passage can be formed by the air supply pipelines and the return air pipelines frequently used in the factory building, so that effective ventilation in the factory building is achieved, and air quality is improved. More importantly, requirements for temperature and humidity of the indoor air and requirements of special application occasions can be met by means of a constant temperature and humidity inner machine. Moreover, ventilation requirements of all areas can be smoothly met through the participation of the air guide assemblies.

Description

technical field [0001] The invention relates to a ventilation device, in particular to an air duct type ventilation device for a factory building. Background technique [0002] For large factory buildings, a ventilated interlayer is set on the roof. On the one hand, the outer layer of the ventilated interlayer is used to block sunlight, so that the roof becomes two heat transfers, and avoids the direct effect of solar radiant heat on the enclosure structure. On the other hand, the effect of wind pressure and heat pressure, especially natural ventilation, is used to take away the heat entering the interlayer, thereby reducing the impact of outdoor heat on the inner surface. At the same time, in order to meet the needs of ventilation, it is often necessary to install ventilation devices on the roof. [0003] However, the existing ventilating device for a factory building is only a single air duct assembly, which cannot form a circulation path, and must be supplemented with a ...

Problems solved by technology

[0003] However, the existing ventilation devices for factory buildings are only a single air duct assembly, which cannot form a circulation path, and must add the necessary blower assembly

At the same time, it is impossible to achieve gas exchange in a fixed area, which affects the overall use effect
