I've been struggling with tagging IDEC (Indirect Direct Evaporative Cooling) systems. I don't tag them as evaporators because that's for refrigerant systems. I want to use coolingProcess but the existing choice items can't be used for evaporative cooling process. Does it make sense to add evaporativeCooling as a coolingProcess choice? I want to know other users' opinions on this and how they are tagging (non-refrigerant) evaporative cooling equipment in general.

I have clients with large air handlers that have both direct and indirect evaporative cooling. I use the tags evapDirect and evapIndirect to distinguish between equipment and points on the two systems.

We use a custom evapCooling tag at the AHU equip level for direct evap cooling, and agree that this should be included as a coolingProcess choice.

We also add a marker tag evap to standard point, sets such as pump commands or air temps (analogous to chillled for CHW cooling equipment).

Thank you for your replies, Paul and Sade. For now, we are going to use evapCooling and evap. Direct or indirect can be subtypes of evapCooling, but we'll ignore that difference to move on for now.
