[TRNSYS-users] night Free cooling

[Filippo Angeli <filippoangeli24@yahoo.it>]

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.

Deal all,

 

First of all, I wish you all a happy new year and all the best for 2021.

 

Two months ago, I updated my TRNSYS version to this one : 18.02.0002. I just realized now that I can’t import a 3D model into a trnsys project., using trnsys3D plugin.

I tried the two different templates that are suggested by SketchUp (I had this problem a few years back and selecting the right templates actually solved it) :

But still, when I try to create a new project with my 3D model in TRNSYS, nothing happens. I also tried a model given by TRNSYS : C:\TRNSYS18\Examples\3D_Building\1_Step_Create_Trnsys3d\ Building.idf

Still nothing.

 

The version of TRNSYS 3D plugin is 1.0.5.1. I tried to look for updates but apparently the server does not answer.

 

Do you know if those two versions are compatible or if there is a newer version of trnsys 3D ? In this case, could you send me a download link ?

 

Thanks in advance

 

Best regards
