.BuildSysPro.IBPSA.ThermalZones.ReducedOrder.RC.OneElement

Information

This model merges all thermal masses into one element, parameterized by the length of the RC-chain nExt, the vector of the capacities CExt[nExt] that is connected via the vector of resistances RExt[nExt] and RExtRem to the ambient and indoor air. By default, the model neglects all internal thermal masses that are not directly connected to the ambient. However, the thermal capacity of the room air can be increased by using the parameter mSenFac.

The image below shows the RC-network of this model.
