Type1288 is appropriate for applications in which the working
fluid's thermal properties change with temperature. The other two
models (Types 1257 and 536) assume constant properties over the
working temperature range. The Type1257 model is designed around a
few particular test procedures used to characterize the performance
of parabolic concentrators. You should use that model if you have
the parameter data that it requires.<br>
<br>
As far as an ORC engine component is concerned, we have usually
modeled these quite simply using a generic performance map component
such as Type42. You'll define the engine's COP as a function of a
few variables of interest (low and high temperature sinks for
example) and then enter this performance data into an external file
to be read by Type42 during the simulation.<br>
<br>
I need a little more information in order to make a recommendation
about the geothermal source. Are you talking about using the ground
as thermal storage or using it as an actual source of energy (like a
very very deep mine or heat exchanger)<br>
Kind regards,<br>

<div>I am new in TRNSYS, so I would like a little help in

<div>Can you suggest any specific parabolic trough model
component among types 1257, 536 and 1288 given the fact that
our goal is to achieve a thermal output power equal to
approximately 200kW (really small scale)</div>

</div>
<div>Considering the geothermal source... I couldn't find any
relative component type!</div>
<div><br>
</div>
<div>Neither for the electric power generator which I have to
apply an Organic Rankine Cycle (ORC) engine. I am aware that I
have to add such a component and modify it afterwards. Is it
possible to find an existing code the ORC generator, or can
you give me any tip on how to make the modifications in the
new component?</div>
