Comms room heat; practical applications

  • A recent AC failure (along with a corporate drive towards a greener stance) has made me put a bit of thought into comms room heat; a mid-size comms room (with the usual assortment of server racks, RAIDs, backup devices, UPSs, etc) generates a pile of heat. We all know this, and pay through the roof for AC to suit.

    But: other than a few jacket potatoes in foil behind the cooling fins, has anybody found any more worthwhile uses for all that thermal power rather than ducting it all away? A few heat exchangers onto the inflow to the building's water-boilers perhaps?

    OK, it probably won't interest the Americans much, but for those countries that /have/ signed up to environmental clauses... ;-p (OK, that stereotyping was a cheap shot...)

  • Trap the hot air, funnel it so its upward force increases, and use it to power a dynamo.

    Then use that dynamo as a power repository for small objects, like recharging your camera batteries.

    I'm not sure how much upward force that air has, but you could find out.

  • Once I saw an indoor AC unit from the server room vent its exhaust right by the bathroom. It worked as a great hand dryer.

  • Wooh.

    I don't think I'd want lots of hot air in the bathroom. :3
