I have turned my garage and adjoining areas (about 700 sq ft) into a fairly
complete home machine shop (cnc milling, 13" lathes, 3 ph elect (via rotary
converters), welding, etc), and last year installed a sleeve A/C *inside*
the shop, via a "plenum box", properly ducted (I thought) to the two clay
vents (about 8" each) that supply an adjoining room.
Promptly burned out the A/C--the exhaust was *very*
hot, indicating that the
vent lines were not adequate--either too small, too long, or both.
The garage is a ground-level basement-type deal, w/ overhead door. The
foundation walls are very thick, and mounting traditional A/C's thru the
garage door is really a hassle.
I'm considering two portable A/C units (12,000 btu ea), which are not really
full 12,000 units, cuz they cheat on the venting, but apparently work.
Since the exhaust on these units is two 4" diam vents, I should be OK w/ my
clay portals to the outside.
Any thoughts on these? Anyone solve shop/basement A/C problems in a novel
PC Richards has 12K Amanas for $549 each, mebbe closer to $500 each if I get
I have two other trad'l units I could use, but like I said, installing them
would be a hassle, as would be another plenum, which might not work anyway.
Appreciate all input.
