Installing these are definitely super easy after you buy the tools. It's definitely cheaper and doable to do it yourself. We have installed 10 units already across our house and my parents house. They are so efficient. We went from spending over $100 each month extra in the winter just to keep our house at a very uncomfortable 65 and $150 to keep it at 70. After insulating the walls and installing the mini splits it's costing us $40 a month to keep the house at a much more comfortable 74.

Installing these are pretty easy if you are handy and patient. Watch a few HVAC pro installs and some good tools. Also best to use nitrogen along with the vacuum. You can test for leaks after the vacuum is done, especially good to test with since you can pressure test with nitrogen and also it helps eliminate the moisture. Pressure testing is important since the heat side runs higher pressure than the AC side, see minisplit specs usually on placard on outdoor unit. I do a triple vacuum to ensure I get all the H2O out. I have a small bottle of nitrogen I got locally and it will probably out last me since I only have done a few of these for my own off grid cabin and a few friends. And yes here in New England it is tough to balance enough sun and battery power with the little sun we get. Just a few more weeks till the days will be getting longer. Well at least it sounds good, but doesn’t help my solar production till around February 😅. Good stuff as always Will.

In my 1400 sq ft Atlanta home, I installed a 1 ton (12,000 BTU) AC/gas heat unit. The "pros" said it wouldn't suffice, but having an MSME I had calculated what was needed, based on insulation (cellulose in walls, R-19 attic) and shading (half of roof from oaks). Worked great, running ~80% on the hottest days. A 2 ton would have cycled more, giving less comfort, and would have been less efficient. "Rules of thumb" are worthless. If not enough, I would have just added more insulation until it sufficed.

Back in the 1970's energy-crisis and DOE funding (Pres. Carter), Solar Energy journal had papers on a solar AC setup. Photovoltaic panels were rare and expensive then (just for satellites). Instead, the sun boiled a liquid which ran a turbine generator. The AC electricity produced ran an AC compressor. Wags fussed that the output of the generator should be judged on its own, compared to grid-power.

@@sophiegrisom I worked on building a smallish commercial office building in the mid-80's which had an unusual HVAC set-up. In a large waterproof pit under it's slab were huge boulders for thermal mass. The roof and attic were designed to collect heat; outside walls were 8" super-insulated and sealed. In the winter the air flowed from attic to occupied space to boulders then recirculated, with normal door usage providing enough fresh air. In summer, the air flowed from those boulders to occupied space then vented out the attic. No precise temp control but all it took were a few damper valves in the ducts set to the season and one fan to create airflow. Always reasonably comfortable (roughly 60F to 75F) and it wasn't much affected by a few cloudy days in winter, but after that it needed supplemental heat. Never needed any help in the summer. I was told the construction was 4X what a standard slab building would have cost, but they expected a 20-year payoff in saved expenses which made it worthwhile. Only having one fan to power makes it photovoltaic-friendly too. The building is still in use so I presume everything worked OK. The thing that bit was there were Federal incentives at the time for passive solar, but since this had to have that one fan the owner was denied when he applied for them. Were I to be rich enough to build a home for myself something like this would be part of it; simple and effective with little to pay for ever again.

One problem that I ran into when installing my 3 zone mini split was that HVAC companies will NOT install mini splits from the internet. The secretaries are trained to turn you around immediately. Furthermore they will not come in and finish your install by charging your lines for you. After being shot down by about 16 HVAC companies I started physically going into their office so they would have to turn me down to my face. I luckily was able to get past one of the secretaries and talk one guy with a soft heart into breaking the company rules and come out to charge my lines. There were 6 splices in the copper lines that needed done as well because I had slightly longer runs than were convenient. But that's it... I did everything right down to calculating the charge for them. They charged me $2500 for this!!! That was more than I paid for the mini split and it was pretty outrageous. But I felt "lucky" to be out of a jam because I don't think that I can buy refrigerant without a refrigeration license. Please comment if I'm wrong and add a link. So to anyone out there that is doing their own install then make sure that you don't get yourself trapped like I did. These units are awesome and easy to install. If you're doing a single zone unit then the refrigerant inside of the unit will probably be enough to charge your lines and you can buy a vacuum pump and be ok. If you buy a multi zone unit then you will probably get stuck in my position so make sure that you have things figured out before you purchase your unit. Will... if you're reading, then it would be really cool to encourage EG4 to go the Mr Cool route with the line sets. I doubt they can build their own but they seem to be a pretty crafty company and maybe they can license the patent? It's cool to be able to hook solar up to the mini split but at this point I'll definitely go with Mr. Cool for my next install.

I’d note that pulling a vacuum and doing a triple e-vac is not the only step to get these to work. I’d also disagree with the notion that these are “easy” to install and get working properly. After pressure test and evacuation (below 500 microns, and hold for one hour) you have trim charge and commissioning. Trim charge has historically been calculated by super heat or Subcooling. These can only been done at a time with an ambient temperature within a certain window. Some VRF systems calculate trim charge by total liquid lineset length. Either way you won’t know if you’re over or under on 410a if you don’t know how to read a PT chart or have the proper tools to generate a startup report. It’s estimated that 87% of DIY home installations are installed incorrectly, out of manufacturer design specification, or installed with code violations.

@@ben3989 In most climates yes definitely, getting heat directly from the sun with thermal panels is going to yield a lot more energy. You don't even need to use a heat exchanger in a big low pressure storage tank if you pump your coolant into your panels. You should have a drain-back system if it freezes in winter though. When ambient is very cold it can be hard to raise the temperature very much because of losses, but in those climates it might be quite inefficient to run heat pumps too. I'd guess that it'd still yield more heat to run a heat pump than running a direct heater element off PV panels.

Verify your system is air tight as best you can before opening the valves and follow the manufacturer instructions when opening them to further check for leaks It is illegal to leak this stuff into the atmosphere on purpose. 2.

Love your videos! But some outside installations look a bit dodgy to me. Like the power connections to the EG4, no water protection? Many areas ask for licenses to add safety. Evacuating heat pump lines is fine but to be sure you have no micro leaks one should have extra tools like a bottle of nitrogen where you pressure test your lines and apply soapy water to any joint. R410 refrigerant is so legacy! It is a blended gas and micro leaks will let out the better of the 2 gases. R32 is a better option but in Europe they are now switching to CO2 as a refrigerant. It requires stainless steel tubing as its pressure is higher. Harder to DIY but more efficient and best for the environment.

It'd be pretty neat to have a look at the internal power supply to see how it's connected. My general guess would be they're running AC power through a rectifier, but the DC power is going in post-rectifier. If this is a DC unit fundamentally, that might mean a slight improvement on efficiency too. (Not that modern heat pumps need that -- crazy efficient as they are!)
@geekstradamus1548
Жыл бұрын
If you run DC power into the rectifier, nothing happens and you end up with DC. Since the rectifier would the the first component of the switched-mode power supply where the DC gets “massaged” to the level the device needs, I’d bet they both sources run to the same starting point. If that’s true, do you think we could just run DC battery power that’s been stepped up through a DC->DC Booster to say, 120VDC and then run the unit off DC 24-hours a day? Skip the power loss of conversion to AC just to get it switched back to DC by the device? 🤷♂️
@McTroyd
Жыл бұрын
@@geekstradamus1548 There's still a diode voltage drop through a rectifier, though. Not much, but when maximum efficiency is the goal, it's not ideal. The thing to bear in mind for using DC over AC is that AC isn't energized the whole time -- it passes through a point of zero voltage 50-60 times a second (depending on your locale). That doesn't make much of an electrical difference, but across a diode drop, that can make a _huge_ difference for heat dissipation. If you can be sure components aren't getting unacceptably hot in operation (thus leading to failure), and the unit isn't using the sine wave to switch electronics internally, it just might be possible to run 120v DC direct. Unfortunately, nobody advertises that level of technical detail about their power supplies. Reputable manufacturers send it for compliance testing with their intended use cases, and that's about it.

Just thought of another thing - when I watch videos of DC boosters, the oscillator on the output end, the signal looks like an AC signal that has the drops (wish I knew the terminology) only go to zero, not all the way down to an inverse curve. Sorry for the kindergarten level wording. I promise I’m a smart man, just ignorant as sin LOL. I was worried this meant the DC power on the output end of a DC booster wasn’t clean, and would trick the mini-split into thinking the PV was dropping below its threshold and force some kind of constant switch back and forth to AC, which probably would be horrendously bad. But maybe these DC drops would be helpful??? Are they even DC drops or is that just the way some oscilloscopes show DC power??? Would these drops even be measured since it might not look for a power drop until the backend of the SMPS? Why didn’t I spend some of that down time in the Infantry reading about electricity/electronics instead of Sports Illustrated or Maxim??? If you know great, but honestly I need to school myself up a lot more before I get a builder involved in this DC house I am interested in building, and I’m sure you already have a job! LOL

@@geekstradamus1548 All good. In fact I have no formal training here either... just been tinkering with the stuff and watching KZitem for years. 😁 Both DC boost converters (make voltage higher) and buck converters (make voltage lower) use rapid switching to accomplish that goal. In the case of a boost converter like you mentioned, a low voltage is sent through an inductor at high current, and then the current is interrupted. That causes the voltage to spike upward for a short time, while the magnetic field around the inductor collapses. That's the positive-only rippling on the output you see in the oscilloscope. Usually, good converters will put bypass capacitors and common-mode chokes on the output to average out the voltage, so it appears as straight DC, unless you're drawing too much power. So if you're seeing serious voltage ripple on the output, either that's a crappy boost converter, or too much power is being drawn for the filter capacitors to keep up. That can create noise in sensitive electronics, too. Conversely, a buck converter takes a higher voltage and chops it up at high frequency, then sends it through similar filtering to smooth out the ripple.

People PLEASE read this. The reason your local HVAC folks won't help you isn't greed. It's because they use only stuff they know and trust and that applies to their suppliers too. If they get a dead unit or part they can quickly sort it out, but not when you bought it elsewhere. They have their tools and knowledge focused on the stuff they use, and varying from their formula means lost work efficiency. They don't need this when they're swamped with work already. Their reputation depends on having no call-backs and using something they don't know intimately increases that chance. They sure as heck don't want to follow-up on questionable DIY work which they will have to warranty after they fix what you screwed up. They don't need or want your headache when they already have more than enough headaches of their own to deal with already, just like we all do. So if you decide to DIY this, understand from the start that YOUR'E ON YOUR OWN COMPLETELY. It ain't really that hard to do, but most people over-rate their skills, try to cheap out on tools, have no understanding when finesse or extra care is needed and so on. Also understand that there may be legalities involved such as a need for permits, inspections, and trade licenses. Failing here can get you into deeper poop than you can imagine in some places including 5-figure financial losses. Know what you're up against, know what you're doing, know what you shouldn't be doing, and if you have the slightest question or doubt hand the whole project (including equipment choice) over to someone who is qualified to do it. This kind of project is supposed to increase your happiness, not give you nightmares..
