Description

A tuber pipe structure for building ventilation Technical Field The invention relates to the technical field of air pipes, in particular to an air pipe structure for ventilation of a building. Background In a building ventilation system, an air pipe is used as a core component for realizing air transportation and circulation, and the performance of the air pipe has profound influence on the indoor environment quality and the energy utilization efficiency of a building. Along with the development of severe requirements on building function diversification and energy conservation, the traditional air duct structure gradually exposes a plurality of problems to be solved urgently: The traditional air pipe is connected by flange bolts, and in large-scale building ventilation engineering, the air pipe installation involves a large amount of bolt fastening operation, and the process is tedious, time consuming and high in labor cost. And the bolt connection is controlled by the operation precision of constructors, the condition of loose sealing is easy to occur, ventilation efficiency can be reduced due to air leakage, and further the energy consumption of the air blower is increased. Like a commercial complex ventilation system, the fan can perform additional work to compensate the air quantity due to air leakage of the air pipe, so that energy is wasted without end, and the ventilation system runs counter to the aim of pursuing efficient ventilation and energy conservation. When the ventilation system operates, the fan vibrates and the airflow impacts can enable the air pipe to vibrate and transmit, the traditional air pipe lacks an effective damping and buffering design, vibration is transmitted to a building structure through the air pipe, secondary noise is caused, and indoor sound environment is disturbed. In places with high requirements on acoustic environment such as houses and office buildings, once the vibration noise of the air pipe breaks through the environmental noise standard, the comfort level and the working efficiency of personnel can be influenced, meanwhile, the aging of the air pipe and the connecting parts can be accelerated, the service life of the system is shortened, and the requirements of the ventilation system on stability and silence are difficult to meet. Different building spaces, such as commercial buildings with varying floor heights, laboratories with special ventilation requirements, have differentiated requirements for duct mounting height, airflow direction. The traditional air pipe is highly fixed and is difficult to flexibly adapt to complex building space layout, has single function, is only used as an air flow channel, and can not dynamically adjust the air quantity and the air speed according to the actual space requirement so as to realize intelligent regulation. When green building and intelligent building are widely popularized, the traditional air pipe is difficult to be matched with the trend of the ventilation system towards energy conservation, intelligence and high adaptability, and the overall efficiency improvement of the building ventilation system is limited. Disclosure of Invention In order to solve the problems of low connection efficiency, poor vibration and noise reduction, weak space adaptation and function expansion and the like of the existing building ventilation air pipes, an air pipe structure design needs to be innovated, a connection mode is optimized, vibration reduction performance is enhanced, space adaptation and function regulation and control capability are improved, development of a building ventilation system in the efficient, energy-saving and intelligent directions is promoted, and an air pipe structure for building ventilation is provided.
