Information

An air volume to represent a hallway element for a scalable air flow benchmark.

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 IBPSA.Experimental.Benchmarks.AirFlow.Examples.ZoneStepResponse. For this model, a value for mSenFac slightly lower than in IBPSA.Experimental.Benchmarks.AirFlow.Components.SimpleZone has been chosen.

Typical use and important parameters

port_a_toZone and port_b_toZone should be connected to the corresponding ports of a zone model, port_a_toOutside and port_b_toOutside should be connected to the corresponding ports of the OutsideEnvironment. port_a2 and port_b2 can be connected to either a staircase model or to further hallway elements via their respective port_a1 and port_b2.

Validation

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