says 450W = 37.5A on 12V

Thirsty app, but doable if you have a good power source.

The unit draws 8 amps of power. the 450w is the cooling capacity. which is only 1535 BTU. I've looked at these units as well. It would easily fit in the forward baggage compartment, but the cooling capacity is well below what would be needed under a canopy. The units design is for small rooms that will constantly recycle the cooling air and over time step the temperature down. It still may be worth a try just to get some cold air in the face. Just keep in mind, with this unit you will need a way to provide a source of cooling air to the condenser, and also a way to exhaust that air overboard.

thanks flyboykelly, I stand corrected... and would have thought they’d use the BTU as a unit for the cooling work done.

Yep. It's called an "IO-390". Extra cost and weight is about the same as AC, but a lot more fun.

I was 390 before 390 was cool.

Pun intended

I have researched these type units for my 10. If you look, you will also find 2500 watt units (designed for truck cabs) that will put out around 7-8000 BTU's and draw around 80-90 amps at 12 volts after inefficient conversion to 24 volts. They are around 45 pounds and you can find a 10 series alternator that will fit our cowls and put out 100 amps. IMO, This style if far too big to fit in an 8 though. They are 2 part units - Motor/Cond and Evap/Fan

I agree that 450 W would barely be noticeable in an 8 that has not seen serious effort to reduce external air intrusion.

Where did you find the 8A number or am I that blind?

Default cool shirt?

Excuse slight thread drift... anyone tried the cold water cool shirts? I think Doug posted something a while back about it working great but can't find it and then I don't think it was incorporated into his normal flying.

Don't forget that ACs in RVs still take a while to cool the cabin ... so you're still going to have a sweaty wifey unless you get in, crank it up, cool it down, shut it down, get the wifey loaded, start it up and go

I use a cool shirt in my race car on very hot days. It works well, but it’s a hassle and I doubt it would be something you’d want to do routinely. You have to load up a cooler with ice, put on the shirt, hook up the hoses, then undo everything after you use it. Then you have to clean the shirt and put a chemical into the lines to prevent mold. The shirt isn’t trivial to remove when it gets wet with sweat and condensation. The tubing makes it stiff and it sticks to your skin.

I have often thought about the forced air through a cooler system for my airplane. I think it would be much more practical than a cool shirt.
