Enyuan,<br>
Type1231 was developed based on correlations to model a heating
radiator, not a cooling radiator and it is likely that the
correlations simply do not hold true in cooling applications. I
would look to a different model. I would also be a bit careful;
most in-room cooling radiators operate above the dewpoint because
getting condensation all over their surfaces causes other problems.
<br>
<br>
As for connecting Type1231's output to Type56, define an energy
gain input (as opposed to a constant value or a schedule) in the
zone that contains the radiator. Then connect the Type1231 heat
transfer output to the gain input. I would recommend that you split
the gain about 80% convective and 20% radiative. Despite their name,
most radiators do significant heating by convection.<br>

<div class="yiv5072951955gmail_default" style="font-family:arial, helvetica, sans-serif;font-size:small;color:#3333ff;">I'm
trying to model radiant cooling using the type 1231 radiator
in TESS library for TRNSYS 17. The model may be loose for
cooling as condensation is not considered, but we want to have
some idea of the effect when only convection and radiation are
dominant. I'm looking for answers to two questions:</div>
<div class="yiv5072951955gmail_default" style="font-family:arial, helvetica, sans-serif;font-size:small;color:#3333ff;"><br>
</div>
<div class="yiv5072951955gmail_default" style="font-family:arial, helvetica, sans-serif;font-size:small;color:#3333ff;">1.
Is there any example or tutorial that shows how the radiator
can be used with type 56, or how they communicate?</div>
<div class="yiv5072951955gmail_default" style="font-family:arial, helvetica, sans-serif;font-size:small;color:#3333ff;"><br>
</div>
<div class="yiv5072951955gmail_default" style="font-family:arial, helvetica, sans-serif;font-size:small;color:#3333ff;">2.
In searching previous threads on using the radiator, it seemed
that there's restriction on the inlet water temperature, that
it, it must be at least 0.5C above the room temperature. Can
we circumvent this restriction?</div>

Alasdair,<br>
Are you getting the "component load failed" message when you try
to drag an instance of Type230 out into your Assembly Panel or when
you try to run the simulation? When I try to duplicate your steps, I
get the "component load failed" message when I try to add Type230 to
the project. The reason for that is that Type230's proforma was
created with Trnsys17 and so is not backward compatible with
Trnsys16. Type230 itself (the DLLs and the source code) both look to
me as though they will work in v16 as well as in v17 so you could
open the source code and determine what the parameters, inputs, and
outputs of the model are, then create a proforma for Trnsys16.<br>
