Re: AC Compressor Question
That looks nice. I have 2 stock condensers in the attic but when I do this I want to do it right and work well

Re: AC Compressor Question
Call to confirm, I'm pretty sure it is. There was a guy on here that converted to 134 recently and bought all the parts from old air.

My setup is from Classic air.
http://www.classicautoair.com/ Very nice people to deal with and they know there stuff. I bought the Sanden compressor, brackets and hose kit with condenser for 134A. The tubes are bigger for more expansion so that the 134A will flow better. Thus helps with the cooling effect. I did away with the POA and drier altogether. I also closed off the outside cowl vent for better cooling inside the cab. My AC runs from 40* to 50* depending on how hot it is out side on 100* days it will be closer to 50* but any AC tech will tell you 40* difference is awsume. Mine will stay at the same temp sitting in traffic to. ![]() The kit I got! ![]() ![]() This picture shows the condenser that I installed. ![]() I did away with the old POA valve and dryer and added the accumulator. This last picture shows it since the 6.0 LS swap so the bracket has been changed out. ![]()

Re: AC Compressor Question
It is tube and fin. Serpentine too.
The one in the add I believe they call it "piccolo" in this picture. The universal one I purchased looks like the one one the right. ![]()

Re: AC Compressor Question
That's what I was thinking too. Good visual illustration.. That's why I was saying that I didn't believe the ones offered by old air products as a direct bolt on to be a parallel flow either. They look like that piccolo. Here is a pic of their condenser

That's because the kit picture is a generic picture. It shows the dryer also. Which I don't have, it's a generic and they sell you the one you need, Da!
It's made for the 134A Freon. ![]()

Re: AC Compressor Question
This is usually the case...which is why people should call and ask. That will remove all doubt and answer the question.

Re: AC Compressor Question
oh ok, I just thought what was in the pic is what one would get. Either way, neither one in the generic pic or the one on your truck is a true parallel flow condenser. At least not by the pic above showing the different types on condensers. But if it works then it doesn't matter.

Re: AC Compressor Question
If it's working for you nobody is complaining.
It's not the "expansion" that is important as we're talking about the "condenser". To condense back to a liquid we have to get rid of the heat. That is done with more contact area via the tiny tubes. Parallel flow lets the liquid to drop out while the hotter vapor to stay in the top of the condenser. Simply put, R134a requires more condenser than R12 to get rid of the heat otherwise pressures are higher and the system is less efficient.

Re: AC Compressor Question
[QUOTE=Andy4639;7256425]I never said true parallel flow condenser for either one. I said they sold this one to me for 134a only with more and bigger tubes for expansion. I have no idea where you got the true parallel flow condenser part.
My system works great! I was just putting info out for a swap that I performed back in the early 90 and has work with no problems since. ![]() There was probably a misunderstanding. The discussion of parallel flow and where to buy started before you posted. That's where "the true parallel flow condenser part" came from. |
