Model of a slab-on-grade floor, the ground is modelled as purely conductive and considers solar fluxes transmitted through windows
Hypothesis and equations
Inner floor on a slab-on-grade floor model with a boundary condition on underside temperature (ground temperature). Modelling considers only the 1D conduction within the floor and the ground. On the upper side, convection and long wavelengths exchanges are modelled by a global surface exchange coefficient hs
. The optional parameter RadInterne
allows to take into account short wavelengths flows.
The parameter SurEquiValentTerre
allows to take into account a ground layer whose thickness, mesh and type (clay/silt or sand/gravel) are defined in the Ground parameters section. In case this parameter is False the ground constituent material must be considered in the CaracParoi
parameter.

Instructions for use
Complete the parameters regarding the type of models, inclusion of short wavelengths solar flux as well as a layer of a ground equivalent under the floor.
Complete the parameters of the slab / floor especially on the surface, the surface exchange coefficient and the characteristics of materials used. If SurEquivalentTerre
= True is selected, fill in the Groud Parameters section information on the thickness of this layer and its discretization.
Complete the parameters for initialisation.
Known limits / Use precautions
none
