Monty, you could also see if you can work in the same type of system that
I'm planning. Follow my logic for a moment.
When do you need that extra
bit of cooling? ...on really hot days at low altituded.
When do you wish most
that you had airconditioning in the plane? ...on really hot days at low
altitude!
Since you also plan to move your radiators back into the wing,
see if you can rig up a "heat exchanger with a box on top" in line with your
cabin air intake. On really hot days, dump it full of ice before takeoff. You
get to stay a little cooler under the solar collector. As the ice melts, you
have to get rid of the drippings. Just run a drip tube to an exit that's in
front of the radiators. Presto! Two birds, one stone.
This is easy on the
Delta. Big fat strakes in front of you that are basically empty space. I have no
idea how it would fit in your project.
Ernest,
To put some numbers
to this: A typical car airconditioner has a 5Ton rating. Smaller cars may get as
low as 2 to 3 tons. This is the same size AC unit as your
typical house.Think about sitting in a metal box with a greenhouse on
it with a black leather interior, black paint, a huge V8 pumping out
the heat and a nitwit who wants it cool NOW after it's been in the
parking lot in Phoenix all day at 125 deg and you will understand why they
are so big.
A ton is the amount
of heat a TON of ice can absorb (typically in an
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
use dry ice and a cool vest like the race car guys. Don't try to cool the whole
airplane.
