You know Millions bought into fuel
line magnets, and intake Vornadoes, and special carburetors and all kind of other claims too, and so far as I know no company was sued and out out of business, but you know these devices don’t work
unless you believe the Oil
Monopolies really do block technology as simple as a magnet.
Likely one of the better examples of efficient AC’s is the existing “mini splits” that are often Japanese and or Korean made, they are inverter Comoressors making them I’m pretty sure BLDC motors and they are infinitely variable speed.
The Toyota Prius AC is the same as is our AB style marine refrigerators, BLDC or “inverter”, all brushless DC motors are, but inverter brings marketing
magic, like titanium or carbon fiber does.
They are pretty efficient over a simple old on/off compressor, but not by a whole lot.
Sure these things are capable of pulling very low current
, but they do so by producing very low cooling
, an on/off compressor does actually pretty much the same by cycling.
Where the increase in efficiency comes from is when they run at very low speeds they are essentially small compressors, but the evaporator and condenser remain the same size, and by increasing especially condenser size, you get an increase in efficiency.
Remember the old heat pumps? Small boxes with one side had what looked like a car radiator, well that was the condenser, newer heat pumps are often round, at least twice as tall and the condenser wraps around the entire thing, the condenser is several times the size it used to be, this lowers the temperature differential and the smaller the difference, the higher the efficiency.
Marine AC’s almost always give up evaporator size and to an extent condenser size in order to have a physically small package that will fit in a boat and not take up as much size.
Unfortunately there has been no great leap in efficiency, no 200% or greater increase, I really wish there had. It would go a long way towards solving a lot of problems we have now, it may even free up a lot of power to power electric
You have to compare btu output to btu output and if you do there is no great difference.
There is an increase in efficiency in slowing down a compressor and running it 100% of the time as opposed to turning it off and on, look at the Adler Barbour new AEO controller that does that, but it’s not a huge jump, or we would all be extolling it’s virtues and everybody would have one.
