Fresh air rate/Recycled air rate

Postby Geert Bellens » Wed Jul 05, 2017 2:33 pm

Is it possible to evaluate the fresh air rate together with the recycled air rate in Designbuilder.
I only can see the fresh air, but with AHU's using recycled air, I also want to see how much % recycled air is used.

Best regards,

Hi Geert,

You can check the airflow values at several nodes on the Air loop by enabling the HVAC nodes outputs. These outputs can be analysed using the Results Viewer.

Thankx Luis.

Would be interesting to have this view (in m³/s or m³/h) in Designbuilder also, together with the fres air rate (in m³/s or m³/h, not in vol/h)....

Greetings
