A Green Air Conditioner?

Posted by Phoenix Woman on March 12, 2008

They’re working on it:

SolCool One, LLC and its manufacturing partner, Senergy Cooling Systems, delivered the first Millennia direct current air conditioning/heating system to AirCare, LLC Phoenix, Arizona.


The 1.5 ton, 18,000 BTU split version of the Millennia demonstrates how it uses solar or wind DC and or grid AC energy sources to charge on-board deep cell batteries that power its 24 or 48 volt internal system. The battery driven Millennia can cool or heat uninterrupted for hours without any charging from outside sources at more than 50% less power consumption than comparable conventional hardware.

“The Millennia will smart charge from solar, wind, hydro or any other direct current choice and if there isn’t any DC source it will automatically charge from a grid or generator source. If charging is interrupted, the Millennia System will continue to cool, heat, light and charge DC accessories such as cell phones and laptops from it’s own battery bank for hours or days”, said Cliff Sutton, V.P. Marketing & Sales at SolCool One, LLC.

Of course, having CFLs and now LEDs instead of incandescent lighting will help ease the cooling burden the A/C must shoulder. Yeah, the lead in the deep-cycle batteries is troubling, but considering that 97% of all battery lead gets recycled it’s not as bad as one might think.

One Response to “A Green Air Conditioner?”

  1. A/C is one of the top no-brainer uses for geothermal. You need really deep wells (or really close to the surface magma) to use the heat differential to generate significant electricity from geothermal. But the best resource for A/C isn’t electricity; it’s cold air.

    It won’t work too well in urban areas; you’d have to dig up too much below ground infrastructure. But once you get about four feet down, you have a constant supply of sub-room-temperature air. There’s plenty of space for the (horizontally laid) piping in most suburban back yards.

    The initial earth moving carries a significant BTU cost. But once that’s paid back, you’re golden.
