New to the field, I want to confirm my understanding of a Constant Air Volume (CAV) system. If an air handler is not attached to a VFD, then it is safe to say it must be CAV? What if I say there are no VAVs/VVTs downstream?
The system I am picturing has a packaged unit ahu with supply air ducted directly into the conditioned space which is a warehouse. Likewise, a return duct brings the air back to the AHU.
