Using Two AC Condensers in Series

[Rhalcorn]

Does anyone know who makes these condensers? They are for aftermarket ac on beetles, they are approx 14" and have #8 fittings on both ends. To connect two condensers in series you would have to have #8 fitting on both ends of one condenser and all I have ever seen have a #8 inlet and a #6 outlet. Also you would need a tube and fin type like the ones shown to mount them horizontally as the capillary type can only be mounted vertically or the refrigerant oil will not flow properly.

My A/C works fine, but I'd just like to make it as efficient as possible.

I wiil have to check my temps coming out of the vents. One tip is cover your fresh air intake in the front grille if you havent replaced the vent flap seals in the dash. Otherwise you will have hot outside air blowing in your front heater vents. Your AC won't be able to overcome this. I used a heavy duty trash bag over front grille intake vent. This is behind the front grille which you must remove to see the intake vent.

Regarding white wrap on the poptop, removal of that every year will be a chore. You need a heat gun and some adhesive remover. But first you must use high quality wrap or it will come off in little pieces instead of a big sheet.

Regarding the rear evaporator, my shop couldn't find a replacement. I think that is the only part they reused.

Has anyone found a parallel flow evaporator similar in size to the factory rear units?

I rebuilt my entire system with R134A a couple years ago. Included a new parallel flow condenser, receiver/dryer, expansion valve, barrier hoses, and compressor. It works well until your pushing 100 degrees on the TX highways, also have ceramic tinting.

Highly recommend the GoWesty Condensor kit if you go that route, makes mounting very easy and it includes the now needed extension hose.

Just curious. If one does a wrap, can it be taken off for the winter months without harm to the paint?

Try the white paint or wrap first. I think you’ll be surprised and may avoid the other measures.

Thanks for the tips Dobryan and Ahwahnee. I was thinking of white vehicle wrap for the top of the poptop instead of paint. Also insulating the undersode of the poptop with a new headliner. Going to see if they can get Aerogel insulation. Used by NASA. I am also considering a double layer top like the tropical top I had on my Land Rover. Get a sheet of Starboard and mount it on my roof rack bars. The only downside of that is it probably wont fit in my garage unless I remove it. I will test a couple of these this summer sith my heat gun. This wiil be cheaper and simpler than dual AC or dual condensers.
I am hoping the tint will solve the problem. I am getting like Ahwahnee
since I am 72 and want to spent less time fixing and more time enjoying life. This corona virus has made me realize even more how precious our time is here on earth. Since I am stuck at home now I am doing some Vanagon work so I am ready to go when this is over.

What Temps are you guys getting coming out of the evaporator in the rear?

Here in hot and humid Miami i am running r134a with a parallel flow condenser. It is not cool enough for me. I do need to retint my windows with that new ceramic tint. My old tint has faded to nothing. I had my system redone a feww years ago with barrier hose, 709 sanden compressor etc. my AC guy (an AC only shop) who is very good and has worked on vanagons suggested a second condensor under the van with an electric fan. This would be opposite the propane tank in the frame rails. He also said he could do dual AC, front and rear with 2 condensers and 2 evaporators. I am going to repaint my tan windows out and replace the window seals and retint first. If that doesnt work then i will consider dual AC or dual condensors. I have also noted heat comes through the uninsulated poptop. Any suggestions on how to insulate the poptop? Mine is painted tan. We have 8 months of brutal heat and humidity in Miami.

I'm on (one) 16x20" parallel with 134 and it does very well in NM 100+deg heat.
