Monty, you could also see if you can work in the same type of = system that=20 I'm planning. Follow my logic for a moment.

When do you need that = extra=20 bit of cooling? ...on really hot days at low altituded.
When do you = wish most=20 that you had airconditioning in the plane? ...on really hot days at low=20 altitude!

Since you also plan to move your radiators back into = the wing,=20 see if you can rig up a "heat exchanger with a box on top" in line with = your=20 cabin air intake. On really hot days, dump it full of ice before = takeoff. You=20 get to stay a little cooler under the solar collector. As the ice melts, = you=20 have to get rid of the drippings. Just run a drip tube to an exit that's = in=20 front of the radiators. Presto! Two birds, one stone.

This is = easy on the=20 Delta. Big fat strakes in front of you that are basically empty space. I = have no=20 idea how it would fit in your project.
Ernest,
 
To = put some numbers=20 to this: A typical car airconditioner has a 5Ton rating. Smaller cars = may get as=20 low as 2 to 3 tons. This is the same size AC unit as your=20 typical house.Think about sitting in a metal box with a = greenhouse on=20 it with a black leather interior, black paint, a huge V8 = pumping out=20 the heat and a nitwit who wants it cool NOW after it's been in = the=20 parking lot in Phoenix all day at 125 deg and you will understand = why they=20 are so big.
 
A = ton is the amount=20 of heat a TON of ice can absorb (typically in = an=20 hour). I think I'll stick with a 30lb Vintage air A/C unit and spray bar = water.
 
If you want an effective cooling system = with ice=20 use dry ice and a cool vest like the race car guys. Don't try to cool = the whole=20 airplane.
