Hallo Filippo, I suppose that you are Italian. In case let me know and I will write you in Italian. If you want to model the night cooling, you can follow two approaches: 1.
You could use Type 2 (controller) in order to get 1 in case the external temperature is lower than a certain value 2.
You could use an equation. Please have a look in the EQUATION Statement and you can learn how to set an equation
with the function "GT" or "LT". You can follow the first or the second approach depending on your experience with TRNSYS. Maybe it would be easier for you
to start with the second approach. I hope I helped you Toni Calabrese, MSc. Wissenschaftlicher Projektmitarbeiter toni.calabrese@spf.ch |

On Behalf Of Filippo Angeli via TRNSYS-users Good evening, I want to include night free cooling in my building during the summer season.
How can I build a function that regulates the night ventilation air flow rate, so that free cooling occurs when I have an external temperature
greater than 15 ° C? Furthermore, I want night free cooling to occur only in certain external temperature conditions (for example greater than 24 ° C).
Thanks a lot. |
