A
company that makes rather nice
industrial air conditioners. They are
frequently used to cool large computer rooms where the
building's normal air conditioning doesn't
cut the mustard. There are many
models, including those that
mount in the roof, those who sit on a
raised floor and pump the air conditioning through the floor
plenum, and
chillers that cool
water used in large
mainframes.
There is a room where I
work which has
three Lieberts in it. I always wondered why that
room needed so much
air conditioning; I eventually found out from my
boss that it once had several large
VAX machines in it.
Big suckers that used 220V
power and put out more heat than the average
star. Now the room just gets
ridiculously
cold if you turn them on, so we just leave them
off.
