just read Cronin’s Workshop: Data Centers Hunt for Power (Fall
2008). One solution to part of the power problem at data centers is
to upgrade servers; a solution to the other part is to make the
cooling more efficient. I have a product that is proven to make most
ac units, CRACs, chillers, and RTACs 20 percent more efficient. It is
guaranteed to make them at least 10 percent more efficient. The
product has been on the market since the end of 2001. It addresses an
old problem called oil fouling. The data center world has not
explored this problem because up until recently the electric costs of
cooling have not been the main issue for data center operators and
neither has the total power consumption of data centers. Besides it
is the ac companies’ domain.
takes time to migrate from one area to the next. It is time for
IceCold to help data centers.
We at DegreeC would argue that one of
the best places to “hunt” for more power is right “at home”!
Most data centers simply aren’t
efficient-for lots of reasons. But, as you know, there are a number
of techniques for reducing the demand for power and making do longer
with the power you have now.
We just finished
an installation in which we turned off (or rather put into ready
reserve) almost 1 in every 4 of the client’s CRACs . . . and then
raised the setpoints on the remaining CRACs by more than 3
degrees-all without creating any hot spots. And our system will
automatically turn back on one or more of the reserve CRAC’s should
anything go wrong with the overall cooling.
all, there’s not much more efficient at power consumption than the
data center you don’t have to build yet!
