Information

1. Purpose of model

Low order model of a thermal heat consumer.

2. Level of detail, physical effects considered, and physical insight

The heat exchange with the environment is considered at a low resolution by aggregating the heat transfer through the walls and windows, the heat capacity and the heat gains and losses through solar irradiance, ventilation and internal sources each in one instance.

3. Limits of validity

- No heat transfer inside consumer, transfered heat is directly connected to the consumer capacity

- Lumped capacity and heat transfer

4. Interfaces

HeatPorts for Internal Gains and HeatDemand

5. Nomenclature

(no remarks)

6. Governing Equations

(no remarks)

7. Remarks for Usage

This model uses instances of models from the Buildings Library developed by the Lawrence Berkeley National Laboratory. The library can be downloaded at https://simulationresearch.lbl.gov/modelica/download.html.

8. Validation

Tested in check model "TransiEnt.Consumer.Heat.Check.TestThermalHeatConsumer"
