Hi everyone,

I'm modelling freecooling with precoolled chilled water loop and I have one question. If I understood it correctly, I need to create:

* chiller, type water economizer
* condenser loop with pump

* freecooling chiller as dry cooler with heat exchanger

My question is: do I need to add water-side economizer into HVAC unit? In reality I dont have this coil, but I am affraid, there isn't another option how to model free cooling. What are your suggestions?

Regards
