modelExteriorWallContainer

container for exterior wall RC element that has the option for a pass-through

Information

ExteriorWall represents heat conduction and heat storage within walls. It links a variable number n of thermal resistances and capacities to a series connection. n thus defines the spatial discretization of thermal effects within the wall. All effects are considered as one-dimensional normal to the wall's surface. This model is thought for exterior wall elements that contribute to heat transfer to the outdoor. The RC-chain is defined via a vector of capacities CExt[n] and a vector of resistances RExt[n]. Resistances and capacities are connected alternately, starting with the first resistance RExt[1], from heat port_a to heat port_b. RExtRem is the resistance between the last capacity CExt[end] and the heat port_b. In this model, the variable pass_through defines if the RC is installed or not.
