Probably, a bubble has been trapped in the mixer valve which TRNSYS considers it in the simulation. As you know, it is a powerful tool for the users.

Dear Arian
I wonder why while the collector outlet temperature (Mixer inlet temperature) is significantly changing, the mixer outlet temperature is fixed all the time. Do you have any idea?
Thank

Dear Hooman,

I am really sorry that nobody has responded to you. As David says always since they don’t have enough resources they can not help you about the basics.

Best Regards,

Arian

Hello, Hooman.

It seems you are using 16 version. Not sure if it is a bug there or not.

Dear friends
In Figure 1 the outlets of two collectors (CPC 1 and CPC 2) with the same temperatures are connected to a type11d (Mixer). Although type11d is not supposed to change the temperatures, the mixer’s outlet temperature in Figure 2 is something fixed, not equal to inlet temperatures…. I wonder why.
Thanks for your help
Hooman
