.IDEAS.Buildings.Components.InternalWall

Information

This is a wall model that should be used to simulate a wall or floor between two zones. See IDEAS.Buildings.Components.Interfaces.PartialOpaqueSurface for equations, options, parameters, validation and dynamics that are common for all surfaces.

Typical use and important parameters

Each propsbus needs to be connected to a zone, which may be the same zone.

Note that this model is not symmetric: the convection equations depend on the inclination inc, which is turned 180 degrees between both side. The value of inc is applied to the right side of the model (propsBus_a).

Parameter hasCavity can be set to true to simulate heat transfer through a cavity such as an open door in a simplified way. The cavity height h and width w then have to be specified. We assume that the value of A excludes the surface area of the cavity.
