Hi all. I am planing a new HVAC system and have a few questions on zoning. Planned equipment:
3 zones -
zone 1- ~690 CFM
zone 2 - ~620 CFM
zone 3 - ~290 CFM
1. Is there a way to tell what the minimum air flow is needed for this equipment? How can I tell what the range of workable CFMs would be?
2. When a zone closes does it close the supply, return or both?
3. How would a whole house de-humidifer work when returns or supplies are closed? Normal attachment for the de-humidifier is both intake and exhaust on the return line.
I think one of my biggest concerns is the ability to de-humidify a zone w/o cooling it. If possible, one solution I could think of, would be to turn on all zones at the lowest fan speed and half tonnage to allow the a/c and de-humidifier to de-humidify but it seems like the possible solutions could get complicated.
Any ideas or help here?
