modeln50Tight
n50Tight: n50 air leakage into and from airtight zone
Extends from IDEAS.Buildings.Components.InterzonalAirFlow.BaseClasses.PartialInterzonalAirFlown50 (Model representing idealised n50 air leakage).
Information
This model represents an air tight zone.
A fixed mass flow rate,
corresponding to air infiltration, is injected into and extracted from the zone.
The mass flow rate is computed from the zone n50 value.
No other air leakage is modelled.
