| Summary: | The article is devoted to the issue of increasing the energy efficiency of ventilation systems and improving the air quality in the working environment of the premises of communication personnel for the maintenance of transport infrastructure when using a new types of air distribution devices. These include textile air ducts made of polyester. This material allows you to cut micro-holes. The advantage of diffusers with microperforation is the possibility of even distribution of air throughout the premises without creating drafts in the working area. The results of the analysis of literary sources on the issue of improving air quality in public buildings are presented. The data on the results of a comparative CFD modeling of the air distribution in the room with two supply air supply schemes: through the supply openings and with the help of a textile air duct with microperforation are presented. In the course of numerical calculation, the distribution fields of temperature and air velocity in the working area of the room were obtained. It is concluded that the textile air duct copes with the task of removing excess heat more efficiently than the traditional ventilation system. |
