[TRNSYS-users] District Cooling Plant performance simulation Trnsys

[David BRADLEY]

Marco,
  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.
Best,
  David
