The development prospect and history of the air distribution pipe

With the continuous development of today's social economy, people's living standards have been greatly improved, and people's requirements for indoor air quality are getting higher and higher. Due to the outbreak of the energy crisis, building energy conservation has become an important issue in the field of energy conservation and environmental protection. At present, countries around the world are exploring energy-saving measures suitable for their own countries, such as increasing the thermal insulation performance of walls, using organic synthetic materials on a large scale, and reducing the amount of fresh air in air-conditioned rooms. At the same time, a problem that cannot be ignored is that these organic Synthetic materials emit a large amount of volatile organic compounds, which will greatly reduce indoor air quality, which violates people's desire for high indoor air quality. According to statistics, people spend most of their time indoors in modern society. The quality of indoor air flow directly affects people's study and work efficiency, and plays a vital role in human health. Good air flow in an air-conditioned room is an important part of air-conditioning design and regulation. Effective ventilation and good indoor air distribution are of great significance for improving indoor air quality, controlling indoor pollutant levels, and improving human health. Therefore, it is very important to study the indoor environment, especially the indoor air flow. At present, the widely used air supply system is the traditional iron sheet air duct system. Although this system has high strength and good fire resistance, it is prone to rust and condensation. The air duct is inconvenient to clean during use, and it is easy to dust and germs. It accumulates on the inner surface of the air duct, which cannot guarantee the maintenance of good indoor air quality. In addition, other parts of the traditional air conditioning system, such as air supply vents, return air vents, and filters, are also prone to accumulation of dust, germs and various microorganisms. These pollutants will With the continuous flow of air to people's production and living spaces, secondary pollution of the indoor environment is caused, and in some relatively closed spaces and office spaces, sick building syndrome and building-related diseases are even caused. In order to maintain the cleanness of the incoming air, the air conditioning and ventilation system needs to be cleaned regularly. However, the cleaning and cleaning of the traditional iron duct is a huge workload, and consumes a lot of manpower, material and financial resources, is expensive, and has an unsatisfactory effect. In addition, because the traditional iron sheet air duct generally uses diffuser air supply ports scattered in the room to supply air, it is easy to cause problems such as uneven indoor temperature distribution and a feeling of blowing in local areas. All of the above limit the further application of traditional air supply systems in the field of ventilation. In recent years, due to the continuous attempts and innovations of engineers in the HVAC industry, technical solutions to improve indoor air quality by applying new air distribution systems have been proposed. It is against this background that the fiber air distribution system comes into being and is getting more and more attention. This air supply system is an air-conditioning terminal device made of a special fiber that integrates air transmission and distribution. It can replace the traditional iron air duct system in some occasions. After use, it only needs to be removed from the air conditioner. Remove the hanging device, and use ordinary washing methods to clean the dust and microorganisms accumulated on the air duct, which can create good indoor environmental conditions and ensure the health of indoor personnel.
