Circulating Fans

Postby 22degrees » Sat May 25, 2013 2:09 am


From the information in the forum it is noted that 'circulating' fans were to be added to the program in late 2012. Am wondering if this feature is available, or how can we go about adding such a system?

Look forward to your reply
Thank you in advance,

Hi Again,
I have since added an assembly within the model to both supply and extract. This can be placed in the space as a desk fan may do.

If there is a more effective way to add a ceiling fan or any impulse type fan please let me know. Thanks again.

The method that you have adopted using an assembly with supply and extract is probably the best solution at the moment. The only limitation with this approach is that the supply air temperature must be defined and cannot automatically be picked up from the extract temperature.

We are however planning to incorporate circulation fans in version 4.0 which should be available this summer.

Hi, I also would like to know whether the option of adding a circulating fan is available in the current DesignBuilder v5. If it is available, how to add circulating fans for the internal CFD analysis? Thanks.
