Dear all,
Our building is supplied with cold water from a DES. The DES consists of scroll compressors, centrifugal chillers and free cooling from a river.

Am I allowed to incldue the free cooling in my EAc4 calculations, so that I fill out the form with HVAC equipment type "other" and refrigerant "none". (since free cooling uses water which has no impact).
- Or am I supposed to do the calculation only for all equipment with refrigerants?

Thank you for your help!
