Air conditioners in a basement.
Air conditioners in a basement.
(OP)
I've got a project where an owner wants to put (5) 10-ton air conditioners in an enclosed basement parking structure. The block load of the building is approx 32-tons, the elevation is 5500 ft. The parking structure is 6000 sf and approx 12 ft high. The condenser fans move approx 36,000 cfm (on high). I'm rejecting the 32-tons to the space every hour (plus compressor and fan heat), but what I don't know is the ability of the floor to absorb that heat (the walls are insulated). At what point will I lose control of the system? Is there any ability for the floor to coompletely re-charge in a single evening.

Is the space ventilated?
Whats above the basement area?
First reaction is that this is a bad idea for a number of reasons.

I agree that this is a bad solution. My client (and his contractor) is convinvced that it's not and I'm trying to quantify it. I can predict the heat gain to the space from the air conditioners. What I can't predict is the rate at which the sub-grade floor will accept this gain, and what potentially will be my garage temperature by 4 pm.

If it's not insulated, the problem is probably not solvable.
Because the owner and contractor think it will work doesn't mean it will work. You are the Engineer.
