.Annex60.Experimental.Benchmarks.AirFlow.Components.Staircase

Information

An air volume to represent a staircase 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 Annex60.Experimental.Benchmarks.AirFlow.Examples.ZoneStepResponse. For this model, a value for mSenFac slightly lower than in Annex60.Experimental.Benchmarks.AirFlow.Components.SimpleZone has been chosen.

Typical use and important parameters

port_a_toHallway and port_b_toHallway should be connected to the corresponding ports of a hallway model. port_a_top and port_b_top can be connected to another staircase model via its respective port_a_bot and port_b_bot.
