General Formalism for the Computation of Radiative Heat Transfer inside Buildings

Popis výsledku v původním jazyce

Thermal performance of buildings is under permanent investigation since heating in buildings represents essential financial part of the operating cost. Heat loss is an unwanted phenomenon that increases demand for financial sources and thus the precise evaluations of heat losses are desired. A common procedure used for the evaluation of heat loss is based on heat conduction through walls. The interior and exterior temperatures along with the total thermal resistance of the wall are crucial parameters for determining heat loss. The temperatures in the vicinity of walls are considerably influenced by the thermal radiation emitted by the heating system installed in the room. In order to take into account this influence, it is necessary to develop a computational formalism for radiant heat transfer in inner spaces of buildings. In the present contribution such a computational formalism is proposed. It employed the matrix of view factors characteristic for the given room and the system of algebraic equations for radiosities and heat densities.
