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.
