[TRNSYS-users] energy bilans for Type 56

[Damien Gondre]

Hi Karol,

I have never used energy balances for zones so I don't know what Qvent,
Qtrans or Qsolgain represent, but have you looked in the multizone building
manual, section 5.4.1.11, page 156 : "Equal amounts of air are assumed to
leave the airnode at the airnode temperature".

I don't know if it helps or not, but I think it might change your vision of
how the energy balance is defined.

Regards,

Damien.
