natural ventilation

Postby hungdang » Tue Jan 15, 2019 11:34 am

Hi,

I have one question. How can I set the external windows are opened although the outdoor air temperature is more than indoor temperature? I am studying on the wind environment in houses in the tropics. Although I set 100% window opened 24/7, windows may be closed when Tout>Tin. So, the results of the airflow rate are 0 in that case of the hot month.

Hi,

You may consider to use the 4-Constant control mode for your windows.
