Information

Hypothesis and equations

From a wall model with n homogeneous layers in pure thermal (1D spatial discretization of the heat equation), this model integrates an intermediate node capable of providing a thermal heat flow depending on temperature and water flow in the case of a water floor, or depending on electric power in the case of an electric radiant floor.

This model was integrated into the wall model of the library that should be used for connexions with indoor and outdoor air nodes to a thermal area.

Instructions for use

This model is to be used as elementary building block for a discretization of an active wall surface, such as a heating floor (default setting).

Surface nodes allow to connect directly incident flows on the surface (eg. Solar fluxes).

External nodes allow to connect temperatures of the environment, however by adding convective exchanges.

Known limits / Use precautions
