[s-cars] Re: Air to Water intercoolers

[Mark Strangways]

Well, it would do precious little on the low pressure side of the
"refrigerant" line, other than to perhaps add some heat to the air stream.
Being in the HVAC business, I have thought of way to use the refrigeration
system to cool the air, but I suspected it may make the air TOO cold, and
strip the humidity from the air. I think so warmth and humidity isn't all
that bad for the air.

It is quite simple to create this air to refrigerant heat exchanger, after
all there is one on board already right.

My thought would be to use water , or a glycol mixture, to cool the air then
use the refrigeration system to remove the heat from that transfer fluid.

But, at the end of the day... Water injection is far better at doing the
whole thing. It's much cheaper, doesn't require any HP and you can add some
methyl alcohol to it for a little added octane.

I have wanted to jump into this tread for a while, but elected not to add my
2 cents till now.
If you wanna play with a air to refrigerant heat exchanger, just go get some
high pressure valve and a evaporator from a similar car. You may have to
bypass some portion of the refrigerant to the evaporator in the HVAC system
so you don't freeze the system with too little load on it.
