Hello Amandine,<br><br>
<blockquote type=cite class=cite cite=""><font face="arial" size=2><b>Is
the Type4 (storage tank) adapted to model an equilibrium
bottle?</b></font></blockquote><br>
I am not 100% certain what you mean by an equilibrium bottle. However,
Type4 is able to model any sized vertically cylindrical liquid filled
vessel provided that the volume of liquid inside the vessel does not
change. Type4 assumes that the vessel is always completely full. If you
need a variable volume tank, you can consider the use of Type39.<br><br>
<blockquote type=cite class=cite cite=""><font face="arial" size=2>I did
not manage to understand how Type4 is operating without any heating
element or heat exchanger;</font></blockquote><br>
The questions that you must answer in the TRNSYS Studio proforma can be a
little confusing. The easiest way to model a tank with no heating element
is to simply set the two "heating element power" parameters
each to zero. In that way, no matter what happens in terms of the tank's
controls, the elements are unable to provide any energy to the liquid. I
would not suggest answering the question "how many heating elements
to be modeled in this tank?" with 0 - simply leave the default
answer as "2." <br><br>
The way that the Type4 parameters are set up by default when you drag out
a new proforma into your simulation is without any heat exchangers so I
don't think that you need to do anything about those.<br><br>
Kind regards,<br>
