The origin 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 in modern society spend more than time indoors. The quality of indoor air flow directly affects people's study and work efficiency, and plays a vital role in human health and 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 particularly important to study the indoor environment, especially the indoor air flow.
