[TRNSYS-users] air contact

[Karol Bandurski]

Dear Jochen,

 

Thank you for your advice, but now I am looking for the values for such
exchange, and the basis for this airflow assumption.

What is your practice with this issue?

 

Regards,
Karol

Dear Karol,

 

You can merge both zones to one zone and two airnodes. Please have a look
into the manual 5.4.1 for the difference between airnode and zone. 

 

1.       if you draw the building in SketchUp, you need to define the wall
as a virtual surface, to merge them in TRNBuild ,use the 180° arrow on the
upper left site of the zone window

2.       If you define the wall manually in TRNBuild ,you can add directly
another airnode to the zone.  

 

After merging you have two airnodes in the zone and you might need to define
an air exchange see 5.2.4.10.

 

Best

Betreff: [TRNSYS-users] air contact

 

Dear All,

 

I wondering how are you model air contact:

 

there is two zones (e.g. two rooms) and they are connected by air (e.g.
doorway), there are no mechanical ventilation or intensive, one direction,
air flow.

 

I think to assume some massless construction between this zones, but what
resistance will be appropriate? Or maybe some both direction air flow, but
how can I assume the value of the flow?

 

Do you have some idea?

 

Kind regards,

Karol
