All:

Please never call me a guru. I am just an "older" user.

Gotta new nifty problem, which someone already knows..

I have an automobile service bay below a dealership in the Los Angeles area. They have 4-10 ton split systems, each 4,000 CFM (16,000 CFM all toll).

There is an exhaust system pulling in 22,000 CFM of outside air through the automobile entrance ramp down into the basement shop...and out the exhaust fan.

I am wondering if I should just call these fan coils (package, and cooling only).  Then I think the outside air is a separate path than having to go directly throuhg the unit.

Winner gets a pretend $100 bill. Thanks.
