[EnergyPlus_Support] Re: is it possible to model 2 air loops
Hello!
I finally managed to work it out. Now I have the two loops but I
wonder if there is a way to connect the relief outlet of one of them
to the mixing box of the 1st one.
The other option would be to use a mixing object but is not what the
real situation.
Thanks in advance.
