modelCO2TransportStep

Model with transport of CO2 through buoyancy driven flow

Extends from BuildingSystems.Airflow.Multizone.Validation.ThreeRoomsContam (Model with three rooms for the validation of the multizone air exchange models).

Information

This model is based on Buildings.Airflow.Multizone.Validation.ThreeRoomsContam. In addition, a CO₂ source has been added to the left room in the bottom floor. At initial time, all volumes have zero CO₂ concentration. At t=3600 seconds, CO₂ is added to volWes. As time progresses, the CO₂ is transported to the other rooms, and eventually its concentration decays.
