Peltier would be quieter, but nowhere close to as efficient. Peltier is MASSIVELY energy hungry...$ 2850 for 5000 BTU is indeed pricy.
Funny, they say "cheaper, compared to Freon air-conditioning" but I don't see the energy usage !!
Except for thermostat, who uses 10w.
It doesn't use any energy??
My Daikin SEER 23.76 use 550w for 8500 BTU, about 450 USD
Knowing Daikin brand, it will run atleast 10 years, more likely 15.
That's normal commercial available product.
I'm always for new invention, especially if it is significantly better.
How much energy do they use?
+Edit after reading some more.
They don't, as they don't "do anything"
You need to buy air compressor.
The compressed air is placed in a vortex that automatically makes a hot and cold section (physics)
" That's all folks"..
I do not know how noisy the air compressor in USA are, but here they are noisy!!
And use a lot of electricity.
It is idea for lower cooling range (500-2500 BTU), using peltier pads with ventilator is much much more energy efficient and cheaper!!
Or refrigerator?? Not that hard to change the thermostat to start at 20 Celcius..

Two innovations that I like are the inverter driven compresors and variable speed fans. Inverter driven compressors can be modulated and they do not need the start up Amps that regular compressors need. That makes them more energy efficient and ideal for homes running off batteries. Peltier has been around at least 50 years and i don't think it will become more efficient.This is one of those areas that continues to evolve

My van roof was 130 outside and 112 inside at 5pm Monday past....metal heats in the sun. Mexico- Arizona border area45C? Where do you live that you see 113F temps? Right ON the sun?
I used a Vortex cooler on an explosion proof (EX) electrical enclosure. Very expensive to run, but in that application choices were very limited.I'm aware peltier like to eat.
I have small air compressor.
Then it's running it uses about 500 watts and is loud!!
It is not sufficient to have enough pressurised air to do the 5000BTU fortex cooling.
550 watt gives me 8500 BTU.
If we talk about small location, low BTU like 500 - 1000, peltier might use more energy, but price wise...
So much more cheaper.
You can buy extra panels and batteries to compensate and still end up with more cash in your pocket.
Peltier is small.
You can place several small ones in cramped space.
Alternatively use refrigerator.
(The small camping type refrigerator ofen are peltier also)
Compress air to the pressure needed for the fortex cooling is not energy efficient.
As result, fortex is not efficient.
It does however have special feature, it can cool in small places.
An alternative that can do the same I know of is peltier pads.
Probably there are more.
Maybe even more energy efficient.
Cooling in small places, "heat" pipe solutions, many options.
Vortex cooling is one of the most expensive inefficient onces.
My van has the spray foam insulation and it definitely works. Much, much cooler inside when I enter the vehicle than my car. I still haven't installed the roof ventilator yet. I expect that should help.I'm in the same situation 4 hours south of you. I measured 130f at the roof line of my van and also currently have the batteries in th e house but the only thing practical I can think of is a small fan blowing directly on the batteries. I am also seriously considering putting another layer of insulation in the ceiling even though I hate to lose the the extra inch of headroom. Keep me/us posted if you come up with something practical.
What part of Arizona are you? I plan on retiring to Sierra Vista in a couple of years. 4600 ft elevation makes a huge difference in the heat (about 20 degrees lower than Phoenix).I'm in the same situation 4 hours south of you.

I made a set, they make a hugh difference, I also installed 2 MaxxAir ventilators, But since my batteries are not installed yet I don't know how much difference they will make. I put an inch of polyiso insulation in the ceiling but the metal roof supports introduce a lot of heat...and as you noted, when the van is not being used..ouch!My van has the spray foam insulation and it definitely works.

One thing that does help is these window sun blockers. They aren't cheap, but the increase in heat when you pull them down is dramatic. They are custom made for your vehicle and they provide both privacy and sun blocking.
I bought a set for my van and my car. Very robust and high quality.

The Victron Smartsolar I am using will output my programmed float voltage even if there is no battery. My plan is to use the SCC to power the fan even without the battery. This is still in the future. You may find it hard to believe, but my motivation to work on the van has flagged a bit this summer.I made a set, they make a hugh difference, I also installed 2 MaxxAir ventilators, But since my batteries are not installed yet I don't know how much difference they will make.

I know it well. My sister had a beach house a bit south east of town. It does get roasting hot there if you are not right on the water.Puerto Peñasco México...in Arizona they call it Rocky Point
