Hello,

I am working on a Modelica model of a District Energy System built using the geojson to modelica translator. I am hoping for some advice on a modification I would like to make.

The GMT builds a district energy system with a Central Heating Plant (boiler) and Central Cooling Plant (chiller). I would like to switch the heating plant to use a heat pump and also use the resulting cool evaporator fluid to do some "shared" cooling for the chilled water loop.

Anyway it looks like I can do this using the Heat Pump Heat Exchanger component as provided in the Modelica Buildings library. I think I should probably use the component by placing it inside the Central Heating Plant and basically replacing the boiler components. I would also need to bring in the chilled water return to make this work.

Is this a good plan? Is there a simpler way to achieve what I want? I didn't find any other components that seemed like a good fit for my needs.

Thanks! Graham
