Has anyone used a dedicated 12V AC system?

Best pic I can find. And yes I was stuck. About 4 years at that point in the pic.

Since this topic has been thoroughly curb-stomped... :flipoff2:

Mine is rusting. A lot. And it's dark green. Need to do something. Sealed up and lasting fine over the rust?
My XJ’s roof wasn’t rusty except for at top of windshield. There’s brown spots starting to pop up, but no chipping or loose paint.

I actually used left over paint to do a test section on my (very) rusty steel deck car hauler I had to really see how well it can actually hold up for zero prep and one ‘coat’. I poured and spread it around (it’s thick, like syrup), even directly over loose rust sand and dirt I could've easily blew or sweep away. To my surprise it held up just fine aside rust staining. I’d had the whole deck painted white if I still had it to not get burned anytime I need to lay down to strap cars down in summer.

I hate painting.
 
I'd rather not since I got the truck over a decade ago with 3k miles on it. So I'm trying to preserve whatever state it's in to keep it untouched as possible.

Well aside from AC and overdrive of course....

Mini split gains a lot of efficiency by doing only what is necessary instead of constantly cycling on and off. So yes but that doesn't necessarily work in a vehicle where heat load is just 100% all the time.

They have gains with refrigerant, pressures, air control, higher voltage, etc. over an automotive system.

Basically a car has the worst situation for thermal management.

Agreed but I'd bet many cars are not optimized in that regard.
Cycling compressor because the evap temp gets too low won't be an issue with a variable speed.
In short I think it's questionable that these deals could cool a XJ, Suburban etc. but a single cab two seater might be ideal.
 
If a methhead can cool their van with the smallest window unit being run off the biggest inverter that's powered by whatever alternator a 1997 Dodge B150 has then I bet this turd can cool a Festiva. :laughing:
 
Not sure the supplier but I remember Toyota years ago had a compressor on the smaller car that had a variable displacement pump that could do just that. It spun 100% of the time and then the swash plate would vary how much the pistons would displace based on need. Pretty cool but it never took off.

(Almost?) all new passenger vehicles do this.
 
BTW, Prius AC compressor (electric) draws close to 2000w for an idea on sizing.
That's less than 200A FWIW


What does a kit like this offer that a junkyard cobbled system with a compressor like that doesn't?

Seems like ease of installation but that's partly negated by difficulty of obtaining service parts.

It runs on the Prius' 200VDC battery though. Guaranteed to let all the smoke out if you tried it with regular 12VDC shit.:flipoff2:

I'd imagine the evaporator housing of junkyard parts is really labor intensive to harvest and not likely universal in its mounting requiring much cobbling to install.
Same for the controls, are they some BUSS type controls? simple on/off switches ?
 
I totally forgot about the condenser. :laughing:


Regardless, doesn't a lot of high trim family hauler shit have a rear HVAC box complete with condenser and controls these days?
