Mathematical Description of Heat Transfer and Air Movement Processes in Convectional Elements of a Building's Passive Solar Heating Systems

Abstract

The article discusses convectional elements of a building's passive solar heating systems. Mathematical description of heat transfer and air movement processes in the convection elements is presented as an equation set in differential form. The set of equations allows the determination of the temperature distribution in the convectional element as well as the heat flow being supplied into the room. At the same time, it is possible to analyze structural factors influencing the heat flow. The mathematical description of the heat transfer and air movement processes is illustrated by examples of calculations and diagrams of air movement in the convectional elements.
