Marco,<br>
My apologies for the delay in getting back to you. We have used
TRNSYS on a few occasions to model central plants. We have relied
heavily on the components in the TESS CHP library in most cases
because that library contains a number of steam components such
turbines, boilers, heat recovery steam generators, etc. The big
advantage that TRNSYS has here is that central plants tend to be
fairly unique in their design. As a result the flexibility of being
able to build the system up out of its components pieces is highly
useful. You could certainly come up with overall plant COP and
energy consumption values. As far as autosizing is concerned, I
think this would be harder. You would have to build up the
configurations and specify equipment sizes and flow rates that are
predetermined; TRNSYS does not have the ability to automatically and
internally adjust equipment size.<br>
Best,<br>
David<br>

<p class="MsoNormal"><span lang="EN-US">I would be very grateful
to receive any useful information in regards to the use of
Trnsys for simulating district cooling plants performance
under a number of different variables in order to establish
system COP, energy consumption and etc as well as to perform
optimum design and integration of others components such as
storage tank . Is it possible with Trnsys to perform plant
sizing under different configurations as well as the above
? Is it possible to perform such task, and if so has anybody
in this forum undertaken such simulation?<o:p></o:p></span></p>
