We have a Combined Heat and Power model currently implemented in Thermoflex (a component based, steady state, iterative solver). We are investigating re-implementing the model in Modelica. The Buildings Library seemed like it should have most of the components we need, but I'm not sure...if I understand it correctly:

  1. The Library does not work with Modelica Standard Fluids and implements it's own Fluid model
  2. The Li bray only works with single phase fluids, water or steam, no phase change
  3. The "Boiler" models are Economizers, there are no Evaporator models

If I'm correct, is there a way to interface a Library component to a Modelica Standard Fluid component?

Our current model has the Components listed below, I've found some in other Modelica Libraries, but I can't find a Condensing Steam Turbine...any suggestions?

Components Steam Boiler Condensing Steam Turbine (turbine driven centrifugal pumps, electric generator, Chillers) Electric chillers Condenser FinFan cooler (Air/Water or glycol mix) Steam/Water separator Deaerator Steam fed Closed Feedwater heater Cooling Tower

Thank you, Frank
