modelBuildingTimeSeriesWithETS

Model of a building with loads provided as time series, connected to an ETS

Extends from Buildings.DHC.Loads.Combined.BaseClasses.PartialBuildingWithETS.

Information

This model is composed of a heat pump based energy transfer station model Buildings.DHC.ETS.Combined.HeatPumpHeatExchanger connected to a simplified building model where the space heating, cooling and hot water loads are provided as time series.

Scaling

The parameter bui.facMul is the multiplier factor applied to the building loads that are provided as time series. It is used to represent multiple identical buildings served by a unique energy transfer station. The parameter facMul is the multiplier factor applied to the whole system composed of the building(s) and the energy transfer station. It is used to represent multiple identical ETSs served by the DHC system. So, if for instance the overall heating and cooling efficiency is equal to 1, then the load on the district loop is the load provided as time series multiplied by facMul * bui.facMul.

Note that the parameters QCoo_flow_nominal, QHea_flow_nominal and QHot_flow_nominal are the ETS design values. They include the building loads multiplier factor bui.facMul but not the building and ETS multiplier factor facMul.
