??12 V Electric Air Conditioning Compressor
 

Anybody know anyone that is using this 12 V Electric Air Conditioning Compressor?
I have a old school 383 and I want it nice and clean under the Hood.

Re: ??12 V Electric Air Conditioning Compressor
 

Well picture's sure would help to know what you're talking about.

Re: ??12 V Electric Air Conditioning Compressor
 

Well if you have an extra thousand bucks minimum to blow just to get rid of the compressor it is viable. Sure would be nice on the flathead on my 31 Model A Victoria.

Actually I could use two of the as that would solve the issue of AC compresser on my 48 where I have the 292 with an excess of finned aluminum.

Even at the added 1000.00 cost over a Sanden Compressor I can see guy going for them on rigs where the compressor would ruin the look of the engine compartment. Not worth it if you have a firewall mounted brake booster though as the look is already destroyed.

Re: ??12 V Electric Air Conditioning Compressor
 

Well I don't have anything to start with.
I have to buy a A/C unit.

Re: ??12 V Electric Air Conditioning Compressor
 

That is just the compressor, you still have to buy the AC unit. What you don't buy is the engine mounted compressor and the bracket. Compressors usually run about 200 and the bracket depending on the installation between 50 and 200 and maybe more.

Plus you need the extra hose to plumb the compressor where you locate it. Not a biggie but an added cost.

Now If I could just find a manual rack and pinion for the Jag XJS suspension that I have that won't break the bank.

Re: ??12 V Electric Air Conditioning Compressor
 

I’m sure it would work fine. You still have to find a place to mount it. Let’s say you mount it under the cab, you would have to plumb it to the front to your condenser unit and then into the cab for your evaporator. Seems like a plumbing headache. Commercial trucks have been using “no idle” units for quite a few years. The no-idle units have their own on board battery. So, I’m assuming there’s quite a bit of current draw. So, you may have to mount an extra battery... Seems like a hornets nest of work for keeping it clean under the hood.

Re: ??12 V Electric Air Conditioning Compressor
 

Yes my brake booster and master cyl. is mounted under the cab and my fire wall is going to be slick, I don't really want my heater hoses to be there, but.
I was going to mount the 12 V Electric Air Conditioning Compressor between the inner and outer fender, making a bracket off the fire wall/cowl lip.
and i know that I need other parts also.
Not trying to be a A hole, but back to my Question.
Does anybody know someone that has used a 12 volt system? I can't find ant reviews on them.
My truck is a 1956 chevy.
Thanks for the comments.

Re: ??12 V Electric Air Conditioning Compressor
 

This is the first time I have seen it and probably the first time others have unless as Whitedog76 said they saw them in another application.

You will need a high amp output alternator and I'd go for a high capacity battery.

The one that works for our trucks (unless you have a panel or burb or crew cab draws 31 amps and it fits anywhere you can stick a six pack of long necks. Since I am stretching my cab I'd put it behind the seat next to where I am putting the battery and a speaker or two in a box that would be well enough insulated you didn't hear it from inside the cab outside of maybe a low hum.

I'd be inclined to wait a bit and find out what the feedback was though.

Re: ??12 V Electric Air Conditioning Compressor
 

I've only had experience with the commercial truck units. Sometimes they're a package unit on the back or roof of the cab. Other times they're a split unit with the compressor is under the sleeper.

Anyhow, I do remember seeing this company several years ago. I saw a compressor in the truck of an old Studebaker. As far as perfomance goes, etc... I can't say. If you look on their website, they say 30-50 amps current draw, again that means a large alternator.

Re: ??12 V Electric Air Conditioning Compressor
 

So the 12V A/C one for my truck draws 32 amps.
So what amp alternator would I need?
looking at the chart
http://powermastermotorsports.com/te...Alternator.pdf
Head lights 6
dash lights 4
my elec. fan is 10
HEI ignition 12
12 A/C 32
Elec. vacuume pump
for break booster 10
my draw would be about 74 Amp.

Thanks for the info.

Re: ??12 V Electric Air Conditioning Compressor
 

10 or 12 SI alternators are pretty easy to find in the 100 amp range

You would probably have to re-clock it but stock alternators for 85 Cad Devilles came in 108 or 120 amp ratings and aren't hard to find. I've got one out in the shed that I plan to stick on my 48 that was on the last mid 80's Deville we had. I bought it a couple of months before something gave out on that one and pulled it off and kept it.
Or you can go buy a fancy one with 100+ amp output.

Re: ??12 V Electric Air Conditioning Compressor
 

cool

Re: ??12 V Electric Air Conditioning Compressor
 

Understand that the size of the wire is going to be 1/2" Diameter. Not quite as big as the heater hose but large enough.

Re: ??12 V Electric Air Conditioning Compressor
 

Actually, #4 AWG will get you 30ft. Even if you upsized to #2, it's only about 1/4" diameter.

Re: ??12 V Electric Air Conditioning Compressor
 

DC current adds more heat. More voltage drop.

Re: ??12 V Electric Air Conditioning Compressor
 

Bus a/c units typically have two to three condenser fans and two to three evaporator fans across multiple evaporators along with a second battery to reduce surges caused by fan and compressor cycling. Draw on the alternator can be 30 to 50A at idle! Between lack of charging at lower RPM and heat production at higher RPM the alternator may have one helluva job maintaining a charge. If you're in an area that gets warm and your vehicle is expected to do a lot of idling or stop and go driving you should plan to use a more robust alternator than an "upgraded" 10SI or CS130 style unit. At a minimum I would ensure selection of a 12SI alternator such as Delco 321-594 with an "undersize" pulley for an older bracket system. If you can fit a CS144 alternator there are more options all the way up to aftermarket 200A versions although you should be sure to match output and armature RPM to your engine speed so there is sufficient charging at idle. If you have the room an AD244 alternator such as GM 10480390 might be more desirable due to larger case, larger cooling fan, and ample ventilation. With this much current being produced and especially with a smaller driven pulley you should also consider a serpentine belt system to be mandatory. Ultra-cool looking single V belt systems simply cannot transmit the necessary torque to the alternator pulley without putting excessive pressure on the alternator bearings.

sounds like a lot of $$ and work to go thru
look at my build, i mounted the ac real low
can't see it unless you look down

Re: ??12 V Electric Air Conditioning Compressor
 

perzackly.

Re: ??12 V Electric Air Conditioning Compressor
 

Today's E V cars and trucks all have A/C are they all using the same electric compressor?

Re: ??12 V Electric Air Conditioning Compressor
 

If you don't have ANY of the components of a A/C for your ride, why does it matter how much money you spend to get the look and performance that you want.
Thanks to all.

That's badass. Sure, it's expensive, but so is the rest of this hobby (and most others).

Re: ??12 V Electric Air Conditioning Compressor
 

cool race car

Re: ??12 V Electric Air Conditioning Compressor
 

Rencool says they don't sell the compressor by it's self but some searching shows this website that at least did offer it. AS B-Mac said "expensive" https://streetfx.myshopify.com/produ...=5730219950118


Evidently those are an Australian item here is another link https://www.maddair.com.au/Online-St...ric-compressor Thats 1,178.32 United States Dollar at today's rate, still spendy.

Re: ??12 V Electric Air Conditioning Compressor
 

I suppose if you're building a 1300 hp racecar then another $1200 for personal comfort is a small price to pay.

Looks like the streetfx company has 10 left in stock.

Re: ??12 V Electric Air Conditioning Compressor
 

This has peaked my interest. I'm having a 292 built with 4-71 blower, dry sump, crank fired ignition. I also am expecting a cross flow 12 port head. So I have some space issues in my 53 1/2 ton. No distributor helps. I have electric power steering. Also have electric vacuum pump and electric radiator fan. I have a serpentine harmonic balancer and water pump. I will be running duel batteries and have 130 amp alternator. It would help if I could mount the compressor somewhere other than on the front of the engine. I realize they pull a lot of power. Do they work well? Can I expect the same performance as a belt driven unit. It would free up space and make the serpentine bracket setup easier. Thanks for your time and any advice.

Re: ??12 V Electric Air Conditioning Compressor
 

Mick53 I'd say that they are pretty well as new to most all of us here as they are to you.

I'm thinking that they may be used in those big road train trucks that they cross the outback in Australia with and run off auxilary batteries when the trucks are parked and the diver is getting sleeper time. if you study the Rencool site a bit they have a lot of pieces for applications like sleepers or campers.

It would be well worth doing some studying on them though. I don't really want a compressor on my 292 because it messes with the look I want to present On my flathead powered model A the compressor hanging on the engine really blows the look but we have some serious trips planned for both rigs and my wife earned her creds for riding 2500 miles one way in 100 + temps in the 48 with no AC 37years ago in spades when we made a trip to Texas in the truck in the middle of a 45 day 100 degree heat wave down there.

Re: ??12 V Electric Air Conditioning Compressor
 

I'm thinking that Prius, Tesla or other electric or hybrid car electric AC compressors are too high of voltage to use in a 12 Volt rig. Looking up one for a Prius they run 200 + volts three phase.

Re: ??12 V Electric Air Conditioning Compressor
 

The Tesla compressor was operated on 12V. There is a voltage converter that is used with the compressor, likely to step down voltage from main power levels.

Re: ??12 V Electric Air Conditioning Compressor
 

I couldn't find much on the Tesla I did find that the Prius compressor was run on 201 Volts three phase.

On the Tesla club site they say the compressor is run on high voltage while the fan is 12V https://teslamotorsclub.com/tmc/thre...battery.71687/

Here https://teslamotorsclub.com/tmc/thre...s-model.52971/ One of the participants says the Tesla compressor is 400V

Re: ??12 V Electric Air Conditioning Compressor
 

It seems they all run on 200 volts 3 phase. It is just a matter if the inverter is internal or external. I like that the Rencool cools everything with the return gas. More research needed. One of the reasons I went with electric power steering was to get rid of the pump and hoses. Put compressor under the cab. Get their condenser 15" x 15" x 2" with fan, $330. and put under the truck. Run the hoses up the corner of the firewall inside to the evap. Nice and clean. I'm leaning.

Re: ??12 V Electric Air Conditioning Compressor
 

Interesting. Post 8 in the thread I linked reported it was working on 12V. Probably just an internet rumor.
