Foreign countries have strict requirements on the cleanliness of central air-conditioning ducts, and have always maintained high standards in terms of construction quality, management, inspection, and regular cleaning. It seems that there are no requirements in this regard in China. The manufacturing standards of foreign central air conditioners reflect high environmental protection, intelligence, and network characteristics. They have high environmental protection requirements for production processes, materials, and refrigerants, and emphasize air quality. my country’s requirements for the fresh air volume of central air conditioners are generally only 20 cubic meters per hour, and some are even lower. Many central air conditioners with very low fresh air volume have been sold and used; secondly, foreign countries have higher requirements on central air-conditioning air filtration, such as Japan compulsively requires medium-efficiency filtering, and severe penalties will be imposed if it fails to meet the requirements. my country only uses simple filters for central air conditioners, and many central air conditioners cannot even achieve low-efficiency filtration, and there are no penalties; foreign countries have high requirements on central air conditioners and are mandatory, but generally do not have this option in China. Requirements; Finally, foreign central air conditioners are generally equipped with air humidifying devices. Domestic central air conditioners rarely see air humidifying devices, and few companies actively install air humidifying devices. In the initial stage of my country's advocacy of building energy efficiency, the attention of the society was mainly focused on the insulation and heat insulation of the building envelope-doors and windows, walls, roofs, etc. However, with the continuous development of building energy conservation in my country, the energy-saving technology of building envelopes is gradually improving. Fresh air accounts for an increasing proportion of the energy consumption of the entire building. The energy-saving space of the fresh air system is gradually emerging, and the More and more people are paying attention. In addition, in the process of transforming the fresh air system from commercial to domestic use, there are still unacceptable conditions. It is understood that the initial application areas of the fresh air system are shopping malls, stations and other large public buildings, mainly in the form of roof hoisting, and occupy part of the height of the building. However, if ordinary houses also adopt the form of hoisting, it will inevitably cause the compression of the indoor space. These are all problems that need to be solved urgently in the fresh air system. With the continuous innovation of fiber material technology and textile technology in the world, more and more textile fibers with special properties are made into air distribution system, which makes the application field of textile fiber air distribution system continue to expand.
