 |
|
I'd like to set a very high natural ventilation rate (about 50ach) in one zone but appear to be limited to 12ach with the standard Nat Vent template. I have tried to create a new template but seem to be limited to 16ach

You can get around this limitation by switching off the slider controls in the Program options dialog from the Tools menu and unchecking the 'Use slider controls' option.
This allows you to type in data directly. The maximum value of natural ventilation air change is actually 50ach so you can just model your scenario.
I have increased the maximum air change rate to 100ach for future versions.

Dear Sir,
I tried to unchecked 'use slider controls' in order to set the cooling setpoint temperatures 'cooling' to 21.6°C. However I found error in simulation. What might cause this?
Thanks,
Rahmi |

It's hard to say without seeing the model - is the cooling setpoint higher than heating setpoint? Is it lower than cooling setback setpoint?

Dear Sir,
thanks for your reply. I have checked all the temperature setting, and tried to run the simulation. All work well.
Thanks,
Rahmi |
