Fan connecting two rooms - Problem found
« on: November 30, 2014, 07:37:24 am »

Hello everybody!

I have recently created a simple pyrosim model which consists in two rooms separated by a wall. Within the wall there is a hole with a fan, in such a way that it extracts the air from the LEFT room and releases it to the RIGHT room.

I have followed the instructions given in the pyrosim example of a HVAC system, but a problem has arised and the model cannot run, I don't know why.

If somebody could help me, I'd really appreciate it.

I send you my pyrosim model and a pic describing the error that has been found.

Thank you very much in advance, best regards.

Hello again,

In order to facilitate you the understanding of the model, I attach the link with the HVAC example in which I have inspired my model:

Hi Daniel,

You were close. You don't need a hole for an HVAC fan. The vents for the inlet and outlet have to be on the surface of the OBST. There are also a couple of extra vents that I've removed.  I've revised the file and attached it. Also, the flow will eventually die as pressure builds up on the right side of the wall.
