CALCULATION OF THERMAL COMFORT IN THE ROOM TAKING INTO ACCOUNT THE EFFECT OF BUOYANCY
Keywords:
thermal comfort, Fanger method, PMV and PPD equations, OpenFOAM, buoyantSimpleFoamAbstract
Indoor air quality plays an important role as a factor determining the state of human health - it is related to the health and comfort of the inhabitants of the building. In this paper, the indicators of natural ventilation in the premises of the Department of General Physics and Methods of Teaching Physics of Osh State University are investigated. Thermal comfort conditions are obtained in terms of air age and variables PMV, PPD. The simulation was carried out using the buoyantSimpleFoam solver of the OpenFOAM package.
