Have I talked about this before....

[EspanolaGuitarista]

I have an idea....ok....Take a highly efficient heat pump or A/C unit as some call them. I saw a design for a one that ran at 1 hp full load. Now attach this to a air-water intercooler. I bet this heat pump could cool the water close to freezing or perhaps below freezing(unlikely). For 1 horsepower I can can get 1 horsepower for every -10 degrees Farenheit. So how much is the air temperature for a supercharger. I'm sure it's high! If you could lower the intake air tempurature by 100 deg. then that is 10 horsepower-1 for the a/c = 9 hp. The inatake charge is denser = more hp, and less detonation means higher boost. This 9 hp could be tripled! Not bad. Anyways. Just my rant for tonight.

RE: Have I talked about this before....

It is a 1HP motor... 1HP=748W. 1 (perfect) watt is 1V*1A. In our cars, I'm guessing the alternator is putting out 24VAC(RMS). I could be wrong there, but I think its pretty close to that. So, then by doing the math, 748/24=32A of current draw. So, you're alternator is gonna be working alot harder to supply the current draw of the engine and AC unit. And its usually not just the motor, but other components involved in a HVAC system, which will start to add up quickly. If you ever look at a home AC unit, the breaker size is at least 40A. 40A*120V=4800VA (watts), which comes out to at least 6.5hp. And then there is all the added weight...

Sure if the air is sitting still. But when it is moving through the intake then how cold would you need to have it to get the intake air cooled to that temp?

[EspanolaGuitarista]

I really don't know....

The air would be moving of course. I think the the gains would outweigh the drawbacks. The A/C unit draws 1 horsepower from the crank. All the other sytems and loss from that I don't know. Hmmm...interesting. There would be an HVAC system per se. It would be very compact and hooked directly to the intercooler.

RE: I really don

I would disagree that an AC unit would effectivly cool a super chargers intake of air at higher RPMs since heat saturated air is generated internally of course, the AC unit is cooling ambient air temps often high in humidity. I am not sure what the effective static cooling or exchange would be.
Yes 1hp at 742 watts would totally drain the system.

A system built up with peltier coolers and a large array of heatsinks would be more practical as it works with less amperage.

I actually experiment with 2 peltiers on a hotplate with ambient temps fan forced to cool the heatsinks and the hotplate surface was cool to touch. A couple more and it would have gone to freezing point, and the hotplate was on it highest setting of 110C.

Heatsinks used were about the same size as an average CPU heatsink.

peltier coolers...suddenly its all way over my head.

ok, sort of like the 12V cooler/freezers, solid state.

[imported_germ]

CO2 sprayed on your air to air IC would probably be a lot more benificial IMO


im probably going to go with a setup like that for my setup

[geoffinbc]

After all this bullshit just get NOS for a few hundered and dial in you HP gains.

More projects doomed to be over engineered and under built. This thread seems to be right up there with electric superchargers

I think I've seen this actually done on an old stock Jaguar turbo setup, but I can't remember which car (I saw it in a car book). The real question is : the A/C Compressor is going too use around 10 HP. So, using the A/C system too cool the intake charge would have too net more than 10 crank HP for it too be worth it.

[Doubt_Incarnate]

this is a maximum effort kind of idea, true. but thats why we're here isnt it? i dont think even the turbo dragsters do this, they opt for the ice chest thing. and the f-1 cars just used air/air due to weight. besides, he wants to cool the water. if the water heated up to 100F and it was 80 outside to cool it back down to 80 before it hit the intercooler again would cost quite a bit of energy. put a cup of water in the freezr and see how long it takes to lose 20F. use something that sort of simulates the idea, shallow pan.

[TurboZ24]

I would definately never do it with a water too air intercooler then use the A/C too cool the water in the system. That would be a waste. I thought the idea was too basically put an exaporator core in place of an air too air intercooler.

haha put a bunch of peltier coolers (Thermoelectric Cooler/Heater/Generator Modules) on the intake and a huge venting system or run with no hood That should produce enough cooling for a few HP lol

Or use propane refrigerator parts...
