This model represents an non-air tight zone. I.e. the zone air volume is internally fixed to a constant pressure and the sum of the air injected through the two fluid ports is consequently injected in the environment (as if all windows are opened). If a net mass flow rate leaves the zone, then air is extracted from the environment with the ambient temperature and humidity.
