The 200 cfm model of the Arctic Air is a 7,000 BTU/hour system, drawing about 27 amps at 28V or about 750 watts. It was unable to cool the interior like a car air conditioner, but subjectively it did made a lot of difference in comfort. I parked the Mooney on the ramp in the sun, and here in Baltimore it got plenty hot inside the cabin 'right quick' and the portable AC did "Okay" at reducing the heat load. Two summers ago I tested the Ovation with an 120VAC powered unit, one of those "portables" with ducts. I looked into air conditioning alternatives for my Ovation. Here's a link to their website Zero-Breeze My plan is to plumb the exhaust from the unit to the small opening in the top of the baggage compartment allowing it to vent out the top of the aircraft, as far as the cold stuff I’ll direct it into one of the air vents for the rear passengers and turn the other rear vent off along with the scoop on top of the aircraft, this should allow the cold air to be directed by the 2 front vents which are only inches away from my head, hopefully it will make a difference, pirep, taxi and flight test to follow. My hopes aren’t real high on it cooling down the cabin but if it cools it down some I might spend some time plumbing the duct work in. I will sit a thermometer in the plane before hand and see what kind of a temperature drop I get over say 30 minutes or so. Not wanting to modify anything yet I plan on placing the unit outside and duct the cold air in through the storm window (sealed with foam) and see how it works setting in the hangar. An hour later he stopped by and dropped off the Zero-Breeze and said try it out in the Mooney and if I liked it he would cut me a deal, I was closing the hangar as he pulled up so the unit is setting on the table for a little testing on Monday afternoon. The Arctic Air is a big unit and weights in at 50+lbs and draws 45 amps on his 24 vdc system (pretty taxing), while talking to him he mentioned he had purchased a Zero-Breeze unit and tried it, while it does blow cold air it just wasn’t enough to cool the 182 down to be comfortable in a South Texas summer (not sure what he is expecting). While at airport a buddy stopped by and was telling me he was having Dan (our IA) install an Arctic Air system in his 182 so later that afternoon I went by to check on the progress. I ran across the Zero-Breeze over a year ago and had forgot all about it until yesterday. Did some searching on MS for the Zero-Breeze portable AC unit, only found 2 mentions of it in a badly hijacked thread on GTN 750 Audible Alerts.
