.Annex60.Experimental.Benchmarks.AirFlow.Components.SimpleZone

Information

An air volume to represent a zone/room within a building that can be connected to a hallway element and to ventilation equipment.

Assumptions and limitations

This is a very simple room representation. The model is intended to roughly approximate a first order response of the zone to changes in outdoor air temperature. This is achieved by a thermal resistance in model conRoom and the capitancy of the mixing volume represented by the value for mSenFac. The G-Value of conRoom is approximated by the area of one outside wall multiplied with a U-Value of 1 W/(m² K). The value for mSenFac has been estimated from comparisons with other room models as shown in Annex60.Experimental.Benchmarks.AirFlow.Examples.ZoneStepResponse.

Typical use and important parameters

port_a and port_b should be connected to the corresponding ports of ZoneHallway so that there is an air exchange through the door connecting the room to the hallway element.

Validation

This model is following the approach used in Annex60.Airflow.Multizone.Validation.ThreeRoomsContam, only in a more modularized way in order to be part of a scalable benchmark.
