Adriana,<br>
I had thought that I sent a response about this. In case it did
not get to you, here it is again:<br>
<br>
...<br>
It would help to know a bit more about the configuration of your
system: what are you drying, is the material in a big lump, is it
spread out on shelves, is it moving, does it occupy most of the
available space in the chamber or a comparatively small part of the
space, etc.)<br>
<br>
I think you could probably use the Type56 multi-zone building
model for the drying chamber itself. <br>
<br>
I would guess that you would need to write a new model for the
material that you are drying. If the material is quite spread-out
then this might be easily enough characterized by a first-order
differential equation and you even might be able to use Tess
Type693. Type693 is intended to model a thermal lumped capacitance
that heats and cools according to a first-order differential
equation but I imagine that pricipals are basically the same whether
you are talking about thermal capacitance or moisture capacitance. <br>
<br>
If the product is not spread out, if important moisture gradients
develop within it as it dries, or if its drying process is
exothermic (like it is for compost) then I think you would need to
write your own model or collaborate with someone who could write the
model for you. In order to write the model you would need to have
access to a FORTRAN compiler such as Intel Visual Fortran v11.x<br>
<br>
Once you have the model of the drying substance, you would connect
its moisture loss to a moisture gain input of the building (drying
chamber) model.<br>
<br>
Kind regards,<br>
