I was half asleep one night and I got a weird Idea. Normally I forget them in the morning but I remember this.

I thought, If I disconnect my AC lines and round them back into the intercoolers' heat exchanger it would work like a after market CA or Cobra H/E.

I know My AC would be Useless but I rarely use it anyway. If I put a small heat exchanger on the AC I figure it will still work good enough to defrost the windows and such.



Now here comes the questions.

1- Is it the correct design or am I thinking totally backward on this idea, and i don't really know what that thing is???

2- Is it too thin to flow enough coolant to be effective as a , lets say, Cobra H/E???

3- Will it make it so my AC will never work again, even if I reconnect it???

4- Does it lack the cooling ability that I would find in a cobra H/E??? If so, is the difference much or minimal?


I'm figuring this is just a pipe dream because no one else has done it before, but I'm sure most people really like AC.

IDK any help would be appreciated. I'm going to get a closer look today at the cooler to see some way to fabricate them together.

20 views and no one has a word to say.

 

Dude keep the AC a cobra HE only costs like 100 bucks, you'll save some headaches

 

My idea is that this would save some headaches. It's already mounted for example. Also I don't have to try to find one and wait for it to be shipped. IDK, maybe its just a stupid idea thats why no one has done it.

 

Just think if you could use free-on to cool the air! mmmmm

 

Shhh.... Nobody has to know

 

talk about serious cooling

 

I guess youre outta luck man; apparently nobody knows! (I for one sure don't...)

 

put the pipe down and buy a HE and dual pass

 

what if u used the ac (if possible) dual pass an cobra h/e + water/meth and inter cooler sprayer.... that will amek for some cold IAT

 

WTF do you know about this subject?? You most likely don't have either but just want to flame me. If more cobalt owners started thinking out of the box like this and maybe gave me some real input instead of dismissing it like they know wtf I'm talking about the cobalt might get somewhere and over 300 HP. Most of you have all the same ******* Mods. There is virtually no new things coming out. Maybe if some people had some ingenuity there would be some faster cobalts.

So go ahead, flame away, but at least I'm thinking ahead.

 

^^ LOL theres plenty of 300+ whp cobalts. guess you need to read/search more roffle

 

Flame much?? Any input?? No **** there is 300+ horse but plenty??? Maybe 15?? Obviously you didn't get the point I was trying to make.

That statement is about as use full as **** on a bull to anyone besides yourself for your own little satisfaction in finding a mistake.


---Anyway I think some of you are misunderstanding me. I just want to use the A/C's HE. Not the AC pump or AC coolant or any nonsense Like that. I would rout the A/C HE and the S/C's HE together like if I got a cobra one. the I would connect the AC lines strait together, bypassing that H/E and I would replace it with a small one form a junkyard to my defrost still works.

 

Stupid question here - If you are not going to run R-124 through the system. What are you planning to use?

 

he just wants to use the a/c condenser(sp?) as another heat exchanger... not use the freon from the ac to cool the engine... an then hook a tiny h/e (like simalar to a tranny cooler) to run his a/c so he can at least defog his windows... thats what he is asking.... is the ribs in the a/c condenser(sp?) big enough to allow dex cool or soemthing like that (watter wetter an distilled water is what im going to start using in the late spring) to move through it an actually cool down the liquid then go into the stock h/e then to the engine... thats all he is asking..

 

I guess in theory it would work, but it would be much easier to add the second H/E like a cobra one or the C/A front mount one. Something like that saves you the work of breaking the A/C system, and you will not have to do any more work than converting the condensor to hold coolant then adding a smaller condensor. You are thinking outside the box, deinately, but its really not gonna be worth your time on this venture. You could do it just to be different, but thats up to you.

 

see that was my thought.. but if u have a h/e... dual pass.. and water meth... you could do this as another metd to cool down..hell the coolant would cool down just from moving all over the ****** car before it gets back to the engine.. lets re route it to the trunk in a stainless hose also... lol thatd be funny... ANOTHER OUTSIDE THE BOXER!! lol

an ps... i wouldnt put a smaller h/e on for the ac to defog just turn on the air it will make ur windows clear again... i use heat works just as good as a/c.. i barley use ac inthe smmer.. so its probly coming out

 

I would love to see the cooling effect of the free on.

 

Not sure on these cars, but most kick the a/c compressor on while on defrost to help dry out the air

 

Ford ran somthing like that on the Lightning originally, it used the A/C to cool a small bottle of coolant that was dumped into the intercooler whenever full throttle was reached, it worked for like 30 seconds to increase power, and took about 2 mins to cool back down. It was supposed to give 10-15 HP if I remember correctly. Its possible, but not simple. They stopped using it due to complexity I believe. Just something to consider

 

does the freon go into as a liquid or a gas.. if its a liquid i wanna try it lol what would the possible ill effects be if any?

 

You couldn't use it just mixed into the system. You would have to convert the intercooler system to an A/C system. You could have your I/C run at about 35 degrees, but you would have to drive the A/C compressor to make it work, so you would not gain that much power. It might work with an electric a/c compressor, but most of them are too small to handle the heat soak faced in an application like ours.

 

hmmmm maybe i wont tr the freon... and i use the heat on the window vents all the time an it getshott as hell.. so maybe it doesn turn on the a/c?... idk lol

ahh i see what your saying soundsl ike its way to hard for me to figgure out lol..

 

Seems difficult. IDK, I will probably just order a cobra H/E today, No one seems to know about the cooling of the A/C HE. Maybe sometime in the future I can put it along with my cobra H/E If someone figures it out.

Maybe instead of the Cobra's something like this???

Would something like that work??

 

that doesnt look like its for a car.... bu it passes through like 5 times lol... it ******* big

 

Welp, there is a High pressure and Low pressure side to the A/C system ( suction -discharge if you prefer ). So the answer to your question is both. I cannot remember if it comes in as a gas and leaves as a liquid or visa versa that.

To answer the A/C on in defrost mode - yes..100% of the cars on the road do this if you have A/C. GM has a few models out there that keep the compressor on in heat mode as well (Chevy Equinox for example).
