Re: [TRNSYS-users] re-heating after dehumidifcation
Thibaut,
It is not exactly the solution that you are looking for but there is an
idealized "air stream conditioning" device in the TESS HVAC library. You
tell the model what the incoming air condition is and you tell it what
the supply condition that want is (in terms of both temperature and
humidity) and it figures out all of the required energy (heating,
cooling, humidification, dehumidification, and reheating). It would mean
one model per zone but at least you would not have to get into the
complications of modeling an actual air handler and all its internal pieces.
Kind regards,
David

Dear Trnsys users,
I have a general question, as I don't know at all how to do this : Take
into account the energy of reheating after dehumidification.
I simulate a building, which is too big and complicated to modellize
precisely the hvac equipments. But there is a big need for
dehumidification (setpoint 18°C/40%hr for instance) for some zones.
And I don't know how to calcul the re-heating energy without modellizing
the AHUs... I don't have any clue of any method (even non precisely)
that estimate this energy, which can be quite big.
Of course I have the sensible energy for cooling and the latent energy
for dehumidification, but the reheating energy is not taken into account...
Thanks in advance for any help!
Thibaut Vitte.
