Re: Air conditioned intercooler? and mouse update (?)

[ptimmerm@mashtun.JPL.NASA.GOV]

What Mike described is a system that uses a ammonia boiler
feeding a venturi pump, which is used to create low pressure.  
With heat, high pressure and low pressure you can run an 
evaporator and create cooling.

I ran through the math on this system asssuming conservative
numbers.  I assummed heat was comming from the radiator
loop, not the exhaust.  More heat comes out of the radiator
than the exhaust, just at a lower delta T.  The results of
my simple calulations show that an effective intercooler
system using engine cooling CAN be made which provides 3-5 HP
of cooling and drops the intake temp of a 300 CFM motor by
about 40 degrees C. My calucations included all of the ineff-
iciencies of heat exchangers and a total system efficiency of
only 10%.

It seems viable, and with a freon or 134a type working fluid
it would work in the proper heat range and be non-corrosive.

There it is! Take it, build it, report back :-)

p.s. venturi pumps are used in vacuum chambers for those intrepid
sulplus yard scavengers.
