SolCool has a new solar-powered air conditioner, the Millenia, to be released next month. Unlike some of its earlier “full system” two-ton offerings, the Millenia is a good replacement for a conventional window or portable unit for spot cooling.
Practical considerations. The Millenia It can run on power grids in either the US or UK. It weighs about 200 pounds and can be mounted on wheels for portability. It has both cooling and heating functions. It comes with a remote control and a 5 yr warranty.
Green considerations: It’s solar powered so it’s an energy saver. It does require some electricity but will keep going in a blackout, day or night: it can run on solar-charged battery power for up to 24 hours. It’s also a “water saver”: the condensate from the air conditioner can be routed to another SolCool product, the Aquacell, to produce filtered drinking water. What will they think of next?
From the SolCool website:
The version four SolCool has two DC compressors, (one DC compressor will be a heat pump) with on board batteries that will last up to 24 hours between charge cycles. The version four is a 1.5 ton package unit that has a three speed blower and is operated by temperature activated remote control. A two gallon, on board condensate management tank will temporarily hold unit condensation with the ability to pump the condensate to a detached reservoir, drain or an Aquacell bottled water cooler system for filtered drinking water.
The SolCool footprint is 24â€x 24â€ at the base and 48â€ vertical. Vertical height can be reduced to 36â€ if the battery bank is remotely located. Weight with standard on board battery back up is approximately 200 pounds. The maximum draw at full engagement is less than 500 watts.
So it’s an energy saver – but at what cost? About $3000 + $500 for installation according to published reports.
