Description
The steady state thermal model discussed in this paper is devoted to predict the temperatures and heat fluxes through a naturally ventilated DSF, having solar radiation and environmental temperatures as inputs. It is coupled with a fluid-dynamic model, based on a pressure loop, which takes into account both buoyancy and wind pressure at the openings. The model has been validated against experimental data, basing on the prediction of the internal surface temperature of the DSF. Results show acceptable accuracy in the prediction of the heat flux towards the inside, even though they reveal a slight heat flux overestimation associated with dynamic effects. These observations lead to further investigate the role of DSF component capacities in order to increase the model accuracy and its applicability.
