#675 AHU Fan Equip Level Tags

mr lee Thu 28 Feb

I have found some situations where equip-level fan tags would be useful on AHUs. I imagine these would be very similar to hotWaterHeat, elecHeat, or chilledWaterCool, and would serve a similar purpose; that is, to indicate the presence of certain ahu sub-components. My initial proposal for the tags are: • dischargeFan: Indicates that a unit has a fan in the discharge section. • returnFan: Indicates that a unit has a fan in the return section. • outsideFan: Indicates that a unit has a fan in the outside section. • exhaustFan: Indicates that a unit has a fan in the exhuast section. Let me know your thoughts.

For project level work, I see a lot of people do stuff like that. To actually standardize it is tricky, because essentially you could make that case about using a marker tag to note any sub-component of something. We are actually working towards modeling the ductwork in AHUs in WG 551 so some of this might fall out of that.
