001 - Solar Mini Split Air Conditioner Runs 24/7/365 Day & Night

[@danielvinson8099]

I like the setup, as a installer for over 15 yrs I would push the condenser back another 4” off the back of RV because you are loosing efficiency due to sub cooling the refrigeration. (Not getting air flow across the condenser). After doing you will see cooler temps inside on the evaporator unit. Plus maintenance cleaning outdoor unit will be easy also. (Road grime) Just some information other than that awesome install. Really enjoyed video

[@shawnhanes9148]

"I waited a year before I did a video on this". Immediately thumbed up 👍

[@davidb1169]

As a long time HVAC Tech., overall, I liked your video and idea for use. Some things that comes to mind is that a piercing valve is never as good as a line that is brazed. You have more chances of a leak. Your mobile home will flex, increasing your chances of a leak also. On a normal RV rooftop, the connections are not moving separately. Sure, the whole unit will shake, but it shakes as one unit. As far as the air in the line, that may or may not be an issue. Most techs on any system do not pull vacuum long enough to remove all the air/moisture which can turn to an acid in a system. Techs usually assume that the filter/dryer will collect the extra. Your install, is good. All except how close you have the back of the unit against the camper. I would of mounted it out a little further. How are you going to clean the coil good? You need to be cleaning the coil at least once a year and maybe more if you are in a hot climate running it 3/4 of the year and also you have to consider how much rag weed, dirt, etc. is in the air. That is one sure way to kill your system early. Prior to that, it will kill your efficiency. Lastly, for some, if you are going to purchase one, consider to see if you want a heat pump version to give you heat in the winter. There are pros and cons to heat pumps, but I am not going to go into that as my comment is already way too long. If you do get the heat pump version and plan on running this on solar alone, Do Not get heat strips in addition to the heat pump. It will pull way too many amps and your chances of running on solar probably just went out the window. I am not knocking the video at all, just giving some more things for people to consider when doing this. Thumbs up on the video and info.

[@davidc1961utube]

As an engineer that is new to all this RV and boondocking stuff , I appreciate the thought, research and time that went into this excellent video. Now I just need to find the right (small) unit for my needs. Cheers!

Two months on youtube and this guy has 120,000 views. Not surprising. This is great information.

[@patd4u2]

Great idea putting a mini split on your RV, much more efficient than the lousy rooftop AC's that come on RVs, I put a couple of mini splits in my house a few years ago, after getting two outrageous and I mean outrageous quotes to have them installed I purchased mine on the Internet, purchased a vacuum pump and a micron gauge and a tube cutter and installed them myself.

[@rb7491]

HVAC tech here - might want to shimmy that heat pump away from the camper wall an inch or so if you can to get some more airflow. Running a unit with high head pressure can cause all sorts of issues with it.

[@dbkyhere9229]

Wow! Your one of the good guys! Thanks for sharing, such a blessing.

[@SK-or9bo]

Couple of notes on this. When he talks about max power usage, you need to understand that you wont run it on high very often. That is for rapid cooldown. I ran one for years to cool a garage and I always kept it on its lowest setting and it still kept the area in the low 70s if I had run it for a while before I went out there. Some of these come pre charged with freon, that is usually the reason for the long pipe run. It is very important that you don't coil the lines vertically. The compressor oil will get stuck in the bottom part of the coils. The non pre charged ones can have a much shorter length line run. My unit, on low, pulled 1.5 amps. The ceiling fan pulled 1.2 and my big box fan was much more. So you can run these with only a little more electricity than a ceiling fan. I've heard that some of the newer units are over 40 seer. So quiet inside and out. You just need one hole for the power, lines, and condensate line to run through together.

[@gigemags1991]

Thanks for posting this. I was thinking about one of these for my garage. Right now, in the summer, I have two fans pulling air through the garage with doors open on each side. I did not realize these were that efficient. May be getting me a mini split. For me a garage does not have to be cold or hot just comfortable work in.

I worked for a company here in Australia, we built accommodation huts for the mining industry and were fitted with household units like these they had service technicians travelling all Australia servicing the camps and they found that the pipe work inside the units would rub together and therefore fail , so before these cabins went into service we would remove the outer cover and copper pipes that were close would have a coating of Sikaflex ( a brxndname polyurethane sealant) around them so as to stop them from rubbing together.

Good video...I'm a semi retired HVAC Service/Installer and like the mini splits...Their efficiency is incredible...I'm getting close to doing the BoonDocking, have an RV in my drive now I'm working on for a lady couple that does it...A 410A system, roof top heat pump that had lost some of it's charge....Why moron engineers would use 410A in an RV cooler is beyond me...I know the mini spit is probably 410A too, but look how much easier to service....Anyway, thanks for the video....Great idea and damn good work.

[@portnuefflyer]

Sweet! My crane cab has a built in diesel heater, and it is very effective and super efficient, but the cab didn't have AC, until I installed a small (the smallest conventional type AC) Frigidaire 5,000 BTU unit. It cost less then $200.00, and I power it with a 1000 watt Yamaha generator, mounted on the same rotating platform I sit in to operate the crane. It is crude, but it works, and in my defense this was all before mini splits were on my radar, now I would go mini split all the way! Very nice and informative presentation!

Well Done. Couple of things. All piping drain line and electric can go out a single hole in rear, making for a neat install. Other Air Handler models are available. there is a cassette type(4 way blow) flush to ceiling, and there is also an air handler that can hang from ceiling. about 6" H. an alternate to hanging it off the wall. They also make high grade, high pressure flexible refrigerant lines, though soft copper will last if supported correctly.

Enjoyed the video. Thinking of putting one on my Econoline van BigTomsVan. Got 500 watts solar but probably will run the AC from 2100 watt inverter generator. I got to come up with a way to mount the outside unit to the door with brackets. Thanks.chattanooga here.

[@GoneBoondocking]

You are very welcome. Thanks for watching the video.

[@greatscotmagic]

I have the considered the same thing on my Van. Thinking about it now I got some ideas. The bed extendere as might work if you could screw them in to the Van door directly, alternately you could replace the back bumper with a square to bumper and use hitches as David did in the video. Depending on the weight, I have seen folding brackets in wood working videos on KZbin that hold a lot of weight and people have used them With the Bracket that is opened up At a 90ﾟ angle to the vertical upright. It is locked into place and stays that way with whatever tool or item that needs to be horizontal to the floor. I'm going to start looking at these myself. I wonder if you could save some money if you don't use hitches for The bed extenders and even eliminating them entirely and replace seeing them with something else.

[@greatscotmagic]

Have been thinking some more about this and here are my latest thoughts. If you could get a horizontal unit and put it on the roof, you would eliminate the need to build some kind of a support on the back of the vehicle. If it were mounted on the roof, you might then be able to run your copper lines Back-and-forth along the roof. You could use the heavy duty RV tape (I forgot the name) to hold them down. The Tape might give some protection to them. Another alternative would be to run the copper lines inside of PVC pipe and fasten the pipe to the roof. You might even be able to make yourself or have someone make for you a roof rack that the unit could sit on and you could thread the copper pipes back-and-forth through the roof rack.

Interesting Idea, and nice job, Condenser coils seems a little close to the R.V., but if it aint broke dont fix it

[@GoneBoondocking]

I simply measured the fan's airspeed with an anemometer and then multiplied it by the area of the exhaust fan's plenum. That gave me the absolute maximum airflow possible for the intake air of the condenser. I simply doubled that number, just because of the air pressure at sea level, and calculated the distance from the wall divided by the area of the horizon gap at the intake, minus the area on the left side of the unit that is not facing the wall.

I can't wait to enjoy a mini split, because I already installed 800 watts of solar with a 930ah AGM battery bank. I also installed a 3000 watt pure sine inverter and can run my air part of the day. I would rather have a second fan. The mini split would eliminate the furnace that now runs off of propane. Does the mini split heat well enough to be in the mountains around freezing temps? By the way I installed this system on a pickup camper.

Midea is pretty decent, among the best coming out of China and decent bang-for-buck but there is better stuff out there. Daikin, Panasonic, Toshiba, Mitsubishi, Hitachi and fujitsu will probably all offer inverter models with higher efficiencies, lower sound levels and longer lifespans. Virtually all Japanese aircon brands are excellent but more expensive. Also worth looking at models which use the newer R32 refrigerant, which will be even more efficient. If the budget was not restricted, I would go for Panasonic Z-series R32 inverter or Daikin Emura-series R32 inverter. Both of these also have pretty advanced air-purification systems built-in and both are super-quiet.

[@tommotrl]

Great and informative video, David, thanks so much. Two questions: 1. Have you measured the inrush current (instantaneous startup amp draw) of this unit? You need a very high sampling rate meter with a peak amp value hold setting to capture that. The reason I ask is that while this unit draws under 500 Watts operating, it could easily pull 5-10 times that starting up. I know that some inverter controls have some soft start built into them, but practically every electrical device (basically anything with a capacitor in it...) spikes inrush current when it first starts. Especially motors and compressors. This is the true limiting factor in sizing a DC-AC inverter. Its not the operating wattage that kills them (or the devices you plug into them,) but the inrush current spikes, moreso on top of an existing steady load, that you need to size for and/or manage carefully. See Apollo 13 for a dramatic demonstration of the problem. Your thoughts? 2. I couldn't download wall clearance installation requirements for your outdoor unit, but these vary from a low of 2" to over 8". Most are around 4", but that assumes no side restrictions within a foot or two of the unit, which can double or triple the required minimum wall clearance. Your unit appears to be about 3" away from the back wall of the rig. Compounding that, your insulated control and coolant line routing is severely restricting airflow on the inboard side of the outdoor unit, well below any manufacturer's airflow requirements. The likelihood of chronically, albeit mildly, overheating this unit seems pretty high, and if nothing else those lines should probably be rerouted along the side of the unit to restore required wall clearance and airflow. You probably want to double-check your minimum wall clearance requirement from the installation manual as well. Is your outdoor wall clearance really adequate? Lastly, a comment. High-amplitude road shock is not a trivial damage risk to these units, which simply weren't designed for it. The sharp whack of a deep pothole or hitting the lip of a roadway ground down for resurfacing at highway speed could well damage a running compressor. Don't get me wrong, I love this solution and am designing one for myself, but I won't be running it while driving. Good to have you and many others out there finding the limits of these compressors. We'll find out how long they last on the road, which could well be a very long time, but of course, your mileage my vary... Keep up the good work, you're helping make the Internet great again...

Hi Tom. I gotta go in a few minutes but I want to reply, albeit briefly, to your very valid questions first. I retired from the robotics industry and I still happen to have my motor test equipment. This type of inverter motor has a very slow but gradual startup curve. In fact, it takes about 20 seconds for motor ramp-up. So even if the in rush current were ten times operating amps, a 20 second ramp-up would completely smooth out the in-rush current. Any remaining in-rush would be attributable to startup motor torque which actually is well below the 500 watt power needed to run it at full speed. Next, the inverter uses both frequency, not voltage regulation for speed control as well as a reluctance dc motor with extra neodymium magnets to mitigate the torque at the high pressure side of the swing compressor, which also differs from the standard a/c compressor.

Your other comments seem to both concern airflow: heat and airflow restriction. I simply measured the fan's airspeed with an anemometer and then multiplied it by the area of the exhaust fan's plenum. That gave me the absolute maximum airflow possible for the intake air of the condenser. I simply doubled that number, just because of the air pressure at sea level, and calculated the distance from the wall divided by the area of the horizon gap at the intake, minus the area on the left side of the unit that is not facing the wall.

Oh, as to vibration, there are plenty of examples of DC motor/compressor units that are subjected to vibration. My DC RV refrigerator, air bag system, even my water pumps are all examples of rotary pumps driven by DC motors. Historically, few ever fail due to vibration. Most failures occur due to heat, bearing failure, or seals. I hope this helps you, and others, on your Installation. Happy camping!

👍 coming from an HVAC guy you picked a good unit for the purpose they are very reliable and extremely energy efficient.

[@GoneBoondocking]

Thank you, it works well.

[@coconutads]

They are gree units under a different name.

WOW Love Mini Split AC, Thanks for the video

[@GoneBoondocking]

Welcome, thanks for watching my video. Happy camping.

[@yhwhtlc9217]

would it be possible for you to provide a link to the amazon page (or other vendors you might have used) of the items that you purchased, such as the mini-split unit etc.. or at least a list of the product name/model #.. ?

[@GoneBoondocking]

I was planning on doing that already but I wanted to get this video posted quickly because so many people were asking about it. I'll try to edit the description to add the information.

[@yhwhtlc9217]

@@GoneBoondocking Ok, thank you very much, appreciate your channel and being very informative,, I am thinking of eventually doing tiny house/boondocking so getting ideas, just wasnt sure where to start.

[@JohnDWillis]

When will you ad links to the mini split? Thanks!

[@jmbeezleyenterprises]

Great information I would like to know how you ran the copper the process how it connects and how easy it was to coil it underneath that shelf because that was a great idea
