Modeling of Air Distribution in an Office Building Using Microperforated Textile Air Duct

Abstract

Abstract The article is devoted to improving the efficiency and efficiency of ventilation systems through the use of new types of air distribution devices. These include textile air ducts made of polyester. This material allows you to cut micro-holes of a given diameter on the surface of the air duct with a laser. The advantage of micro-perforated air ducts is the possibility of supplying supply air with micro-jets with a small pulse, which eliminates the possibility of drafts in the workplace. The results of experimental and theoretical studies of air distribution using textile air ducts are analyzed. It is concluded that there are no data on the study of the distribution of supply air using textile air ducts with microperforation. The results of comparative numerical modeling of air distribution in an office space with two supply air supply schemes are presented: traditionally, through supply grilles and through a microperforated textile air duct. The fields of temperature and air velocity distribution over the room height are obtained. It is concluded that the use of a microperforated textile air distribution device increases the efficiency of assimilation of heat surpluses in comparison with traditional air supply sources (ventilation grilles).
