[TriLUG] [OT]Machine room environmental controls

[Lee]

I have a small Sanyo AC unit cooling my single rack computer/telco  
closet. It is basically just a small central AC type system... Fan,  
controller, and coils in a small wall mounted unit with compressor  
and everything else on a the pad outside with the other AC units. I  
wouldn't recommend the unit I have as it isn't specifically designed  
for a server room/closet and doesn't restart on power outages, but  
I'm sure you could find something similar to fit your needs. They  
don't require vents or direct access since the coolant is the only  
thing that is piped just like standard central AC. We got ours from  
Bryant heating and air, but any competent heat/AC company should be  
able to find something for you.
