Thread: AC Receiver Dryer Location

Tweet

What's the best place for a receiver dryer and the trinary switch that follows it? Seems that I saw that they can be inside if you have room, but cannot find that reference now that I am looking at specifics Also, if it fits better, does a horizontal unit like Vintage Air's work OK?

I've mounted them up under the dash with no problems, never have tried the horizontal unit but if Vintage Air sez it works that'd be good enough for me...

Thinking about this a little more, how would you deal with the potential of condensation on the receiver-dryer if you mounted it inside? Seems like the dryer, getting that cooled charge from the condenser, could get pretty drippy on a hot, humid day?

Haven't had that problem yet, Roger...but it is a good point... Maybe the temps being cooler under the dash then under the hood control it a bit better??? don't know...

I built a frame mounted bracket just behind the radiator for mine. I didn't want it hanging off the firewall like an after thought wart that so many cars have. Originally I had a nice shiny aluminum version with built in bracket, but the in-out orientation was wrong and with an 'A' roadster, there aren't many options. I finally solved ALL of my clearance problems by taking the a/c out and just installing a heater and have the a/c carefully stored for the "next" car





This was all prettied up before my brain barf and during final assembly

Dave, it may be your drier air farther north, and having it in 'conditioned space' vs ambient humidity may indeed be a factor but I think outside is the right answer.
IC2, I will end up with something very similar, but I think I may spring for Vintage Air's polished horizontal unit that I can tuck to the inside frame rail in your same location. That way I will have one line from the evaporator to the compressor, and one line from compressor to condenser out in view.

Thanks,

The horizontal one would sure be easier to hide along the frame rail or up out of site somewhere up front, Rog....good plan...

Roger - the horizontal was the one I originally was looking for - but no joy at that time as it wasn't available. Good choice though and when I finally do install the a/c in a car, I'll go that way.
