ABSTRACT

High temperature radiant heating is becoming increasingly popular, particularly for industrial and commercial applications. For assessing the thermal behaviour of a room heated in this way some simulation models have been recently proposed: in most of them the radiative heat exchanges between the heating and the surrounding surfaces are very carefully treated, but some uncertainties still remain about the convective components, especially when suitable devices (baffles, etc.) are applied in order to reduce convection (and consequent thermal stratification). In this paper field measurements and comparisons with a model are presented; such tuning allows to evaluate better solutions for the indoor climate, taking into account different configurations of the systems.
