Advanced Engineering Tech - Compressorless AC
02-22-2012, 10:42 PM
Talked to a guy the other day who has a good friend in the HVAC side of the auto industry, and this is what he said. He has come up with a way to have AC, without using a compressor for the freon. I won't go into details because I didn't talk to him myself, but from what I heard it sounds promising. What he did was take copper tubing, and wrapped it around the exhaust manifolds, in doing so it heats up the freon, which expands it, then it condenses, which makes it cold. He didn't know much, but I got what he was saying. It sounds promising, and if anyone else could elaborate on this I would appreciate it. Apparently he is awaiting patents on the design, and I think it would help save a little gas and get some more power. His prototype is supposed to be more efficient than using a compressor, it just takes a while for the manifolds to heat up enough to make it work. I would like to see this work, and if anyone wants I can try and get a meeting with the guy. Anyone think this could be something we could use?

This is how camping and gas burning coolers work. Not sure if it could work on a car as there is alot of movement. Could be wrong though. Also it dosen't really matter if the system is inefficent. Its using a byproduct of the engine thats in plentiful supply. :)

The camping/RV refrigeration are ammonia based cooling systems that use heat to excite and drive the reaction. I have often contemplated an ammonia base intecooler cooling system but have never had the time and mony to design and make a prototype.

thats an interesting idea, I'm sure many would love to have AC and free up some HP. I could see you running into clearance issues, i guess it depends on how much tubing is done around the headers?

You have to realize it is very inefficient method, it requires a much larger system.

Interesting. Win win if the capacity is there.
