Hi everyone,
I have a little problem with TRNFLOW. I have a small house, in which I want to bring fresh outside air in some rooms, and extract used air from wet rooms.
For this, I firstly used the "Ventilation Type" Manager to bring air in my rooms.
My first question is : can I also extract air from a room with the Ventilation Type, using a negative mass flow rate for instance ? Or doesn't it make any sense, since from what I understood, this type only brings air with outside conditions in the room, and assumes the equivalent air volume is removed from the room.. (and going "nowhere", so this would only act as a "gain" depending on incoming flow energy)?
Second, also from what I understood : TRNFLOW can not be superposed to this Ventilation Type Manager. I explain : In my case, I use TRNFLOW and define cracks between each room and an external node at constant pressure (I don't want to include wind effect for now), AND I also use the Large Opening Type to represent doors between the rooms. Does that mean I can't use the Ventilation Type Manager ? e.g. can I supply 50m³/h in room1 with the ventilation type manager, while simultaneously connecting this room1 with for example room2 with a large opening link ? Or does the activation of TRNFLOW automatically cancel the Ventilation Type ? Or maybe it doesn't cancel it but no relation is established between the air supply and the rest of the TRNFLOW model ?
To summarize, my last and real question would be : how can you model air supply/extraction in some rooms while using TRNFLOW ? Do we have to create an auxiliary node with outdoor condition and link it with a fan to the zone in which we want to supply air ? Isn't there a simple way to just impose constant (or scheduled) air supply in a room while using TRNFLOW ?
