АНАЛИЗ РАСПРЕДЕЛЕНИЯ ВОЗДУШНЫХ ПОТОКОВ В ЖИЛЫХ КОМНАТАХ С ПРИТОЧНЫМИ ПОДОКОННЫМИ КЛАПАНАМИ ПРИ ПОМОЩИ МАТЕМАТИЧЕСКОГО МОДЕЛИРОВАНИЯ В ANSYS FLUENT

Abstract

The main problem highlighted in the article is the deviation of the microclimate parameters from the standard values due to the improper organization of airflow in the residential rooms of apartment buildings. The objective is to obtain a working mathematical model of the natural ventilation system, its study for optimization or modernization. The analysis of the normative literature, scientific works of domestic and foreign scientists, developments in the field of natural ventilation and ventilation of residential buildings is carried out. A mathematical model of air exchange of a residential room with convection is presented and analyzed. The flow rate and air temperature, the temperature on the surface of the heater are set as boundary conditions when creating a mathematical model. The features and regularities of airflow distribution in the room obtained as a result of mathematical modeling are revealed. The distributions of air velocity in the room are given. Difficulties of the organization of effective natural inflow of air and the problems with design of valves of infiltration are designated. Technical solutions aimed at improving the quality of indoor microclimate and energy saving are proposed.
