@@solarpoweredge - I've got one on my list too, but on a much smaller scale. I'd send you a link to the video when I get a chance to build it. I'm just in the middle of moving across the country right now, so it will be a while.
I ran an old Danfos compressor this way. I added several capacitors to give it the starting kick. Never got dependable performance. Compressor would brown out and over heat. Good luck.
@@solarpoweredgeA small dc pump would cycle water through tubing wrapped around the compressor body. If you made the water tank large enough you could eliminate the worry of the water boiling, and it becomes an asset (hot water or heat) rather than a problem. Where should one look to acquire affordable DC compressors? I have several window units and portable AC with nice radiators but I assume an AC compressor isn't convertible to DC. It is hard to even search for DC compressor parts because of all the air pumps in the results.
@orangezeroalpha That's an interesting idea. Most larger DC compressors seem to be super expensive these days, I am saving up for one right now. You might want to look around at HVAC equipment that is junked or not working. It's possible sometimes to grab parts from those if the price is right.
@iindium49 Hello, I hope it will work. You might be glad to know I have already built 2 peltier air conditioner test setups - will share those as soon as possible!
@iindium49 Impressive - been keeping an eye out for one of those flame RV fridges to learn with. There is something about this kind of stuff, it is indeed appealing
This is the start of something big, on another video a guy outlines running a fridge from an inverter and the inverter wastes almost as much energy as the fridge uses over the course of the day
@Ben1551 Eliminating the inverter is a big deal. I was able to get a fridge running directly off of solar for some time now, working on a second, but main part of workshop (the cabin) is getting too hot! so now I'm working on cooling that too. There's too much to do
@@solarpoweredgeI've been doing 12v stuff for awhile now, found your channel recently and it convinced me to fix up my 12v kettle, it could never boil water before due to thin wiring. I am now going to copy your mini tin oven idea for my next camping trip, gas cookers are so annoying to use
@Ben1551 That's a solid idea, I guess the copper costs are where they have to cut corners. The 12v plugs on my appliances are usually not too great either. so I am working on replacing them. Your oven idea sounds great. I am slowly building more ovens and should have another one ready to show soon. There is something attractive about portable DC cooking, this idea has to go somewhere...
@@solarpoweredge I'm going to follow your video on the oven and hope it works out, I am also amazed that there isn't more but when it comes to portable 12v things they all get limited by the 10a cigarette lighter port, I use ring terminals and banana plugs for the most part and they do well once soldered, xt60 is the answer but we won't see that in cars ever
@Ben1551 I will add some XT60 alongside 2.1mm just in case I want to push more amps. Btw I really hope a company will see the mini 12v ovens... and fire up a production line for us. Around 25 bucks... I'd have to buy at least 2
I’ve seen a guy who was heavily involved with the science of this kind of thing and he took what was normally used as a cryogenic cooling device and created a cooling device that was completely mechanical and used very little energy but was powerful enough to freeze things without chemicals. The only issue people see with this kind of cooling device is that they are usually too noisy for consumer use. They are very efficient though. So I wonder if you somehow figured out the noise problem would you get the LED of the cooling world
@daniellapain1576 I'd like to see what he's up to, sounds amazing. I am chipping away at several cooling related projects, some with refrigerants and some without. Will be sure and upload anything good I can find
@Brian-1948 I have some lower quality knock off versions of that compressor :D fun fact none of them actually accept DC, they require a variable inverter controller which takes 12/24v DC and inverts it to 3 phase AC! But the label states 12/24vdc. This little compressor is the same way, it runs on AC but is labeled DC. Yet the 3 wires on the top give it away as an AC compressor :) however I am working on a powerful true DC compressor setup requiring no controller, but it's expensive and progress is slow.
amazone 12/ 24 volt dc compressor car fridge/freezer. 12 pack size.. with buffer lithium pac/ for 24 hour operation victron mppt, running all month. awesome, 39 degree IPA in 120 degree suv..? priceless.. also run 120 ac induction hot plate through 2k inverter. want the toaster! off grid in the city!
You & I think alike. For what it's worth, I'm autistic. We should collaborate on a directly connected refrigeration concept. Currently, I use solar to run motors that (through a transmission) compress air. I then run that compressed air through air engines that generate electricity and run freezers (5). I would rather run small (scroll?) refrigeration compressors directly.
@WhatDadIsUpTo The compressed air setup sounds amazing... you do interesting work. We have much in common. Pace of progress has been slooow. I am strictly limited by long term health issues. It's a little better past few months. Also tinkering with air compressor systems and other ideas. Looking at a new piston pump at the moment when I can afford it. There is too much to do. Anyway my goal is to achieve a refrigeration compressor system that is DIY, direct solar (battery optional). 1. Problem is, most compressors (including scroll) are 1 phase AC. 2. BLDC compressors require electronic drive, basically they are 3 phase AC. I am chipping away at this... investigating different solutions and maybe I will find something. Ideally: no inverter, no electronics. Is that possible? I'll keep trying and will share it with you if I get anywhere :)
@@solarpoweredge Hey, me again. This time with a brain teaser. I designed and built a single-piston positive-displacement air engine that achieves a 355° power stroke and has only one moving part. I might put it up on my TH-cam channel one of these days, but doing that'll spoil the guessing game 🤔.
@WhatDadIsUpTo I'm glad you beat that stuff, excellent. Appreciate the offer, east coast here so pretty far away. But it's OK.. my brother has been working with me on improving diet and health etc. better than last year
@WhatDadIsUpTo You have some fascinating tech... maybe one of those motors with a rotating triangular piston? I can't think of anything at the moment, that moves so far. You should definitely make a video!

@NancyDow-xp5sl Stalling and overheating could be a concern, I'll have to keep that in mind

Good luck! I would suggest peltier devices as a direct solar driven thermal pump if your compressor doesn't work out to your liking.

Hello, is it possible to combine a DC PTC heater and a DC inverter mini heat pump (pool 3kw heat pump) to increase the COP?
@HybrydaDrzymaly Hello, it would be possible to add heat to the system using PTC, using a variety of methods. Very interesting idea!
Not cheap but Danfoss have had 12-24vdc compressors for years now, search on their DB35F models, runs directly off batteries.

What drive do you use to run the compressor?
@irfansensoy5901 Hi, all of them need a BLDC drive, you can use any of the cheap ones sold online
Source for compressor?
@mikehughesdesigns You can find them on Fee-bay, that online auction site I really hate doing business with, but sometimes have no choice!
