Re: [EnergyPlus_Support] Re: Earth tube and AHU with EMS
I see that now, it simply adds a heat gain or loss to the zone. So you
would have to psychormetric routines to calculate the exiting WB
temperature of the earth tube knowing the inlet T and w, the total
(sensible) heat gain or loss, and calculate a new outlet T. Then using
the inlet w as the outlet w (w should not change through the earth tube)
calculate the exiting WB using outlet T and inlet w.
