<p>Said,</p>
<p> I am not sure I understand whether you are trying to create a
construction that has 2 layers of heating tubes or whether you are
trying to avoid creating such a construction. Can you please
clarify whether the picture that you included is what you want to
model or if it is what you are concerned might be happening?</p>
<p><br>
</p>
<p> In general, an ADJACENT wall (or floor or ceiling) defined in
TRNBuild does not have any mirroring in it. You create the layers
of the wall however you wish and then you go to one of the two
zones to which the wall is adjacent and you set whether that zone
contains the front or the back of the wall. So if the construction
you create is made up of the layers: sol, dale, tubes, chape,
parquet and you define that construction to be ADJACENT (between
two zones) then one of the zones will have the "sol" face and the
other zone will have the "parquet" face in it. <br>
</p>
<p><br>
</p>
<p> If, on the other hand, you want to have a construction that has
two active layers in it you'll need to define something called a
"direct contact" zone in between them. This is a kind of very low
volume virtual airnode that sits between two BOUNDARY
constructions. Defining one can be confusing so if the picture
below represents what you want, please let me know and I'll try to
explain how to do it.</p>
<p><br>
</p>
<p> Two side notes: <br>
</p>
<p><br>
</p>
<p>1. the picture you sent seems like it is intended for a ground
floor rather than for an adjacent floor (given the compacted soil
layer). If that is indeed the case then you'll want to define the
construction as a BOUNDARY rather than as ADJACENT.</p>
<p>2. you're going to need to sandwich the tubing layer between two
screed (chape) layers. When you are defining the construction
enter the first screed layer as having half of the actual layer's
thickness. Next add the active layer and a second screed layer
will be added below it. You can move the tubing layer up and down
in the screed layer by adjusting the thickensses of the two
adjoining layers but you can't put the tubing at the very bottom
of the screed layer as it is pictured in your drawing.</p>
<p><br>
</p>
<p>kind regards,</p>

The creation of a floor or wall is done from the inside to the
outside.
<div>When I change the construction type of two adjacency

<div>I notice that it applies to the wall or the ceiling of
the other room. I noticed that it is the mirror effect on
the adjacency walls.</div>
The attached figure shows my idea that I have on the floor
study. please confirm this to me, if I m right or not.<br>

<p style="margin-top: 0px; margin-bottom: 0px;">Said,</p>
<p style="margin-top: 0px; margin-bottom: 0px;"> Trnsys tries to
mimic what would happen in a real world situation; if you put
an active layer into a floor that is also the ceiling of
another zone and put hot water through it then the
floor/ceiling will heat both the zone above and the zone
below. To prevent that from happening, you can put insulation
on the side that you do not want to be heated.</p>

Dear All,
<div>I have a question about underfloor heating.</div>
<div>Between the floor and the ceiling of two adjacent rooms
(ADJ_ceiling) . Do you have any idea about underfloor
heating. since we will have the mirror effect on this
floor so we will have two active layers..! or not!</div>
<div>Best,</div>
