[TRNSYS-users] Why type11d changes the outlet temperature?

[Hooman Azad]

Tim

I already tried 11h, still, the outlet temperatures of the mixtures of two identical flows are not the same. I tried to use an equation component instead, to make TRNSYS understand I simply want to mix and divide some flows, with no temperature change, and it worked!

Thanks anyway

Hooman Azad -

If you are wanting to simply mix two fluid streams together use the "Tee Piece" component (11h) rather than the "Controlled Flow Mixer" component (11d).

Tim

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
