Air conditioning article

A newly posted article on RV air conditioning units, some are DC operated.

AC units

It's awesome the article listed a wall-mounted one.


A very possible near future option.:C

Very interesting article. :thumbs up:

The amps are low, but at a meager 6824 btu’s so is the output, meaning it might be a bit marginal in campers with slide-outs, and snaking #2AWG wires (or larger) up to the roof could be a bit problematic for some, though is also available in 24v…Still, a most interesting proposition due the uber efficient what’s apparently a variable speed inverter compressor…Hopefully a sign of more things to come, opening up the possibility of true solar sustaining cooling!

as for the 9200. I have a Lance 1055 its the largest non slide camper lance ever made. I have been out near Vegas when it was 113* and the Polar cub 9200 AC kept us in the Low 70s which is just fine by me and that all I need to run it is a Honda 2000 is another bonus.

This is the first time I have read a article directed to RVers that used a fraise like "many truckers use".
Many of them have spent a lot of time using 12V to make life better.

Keytag,

I was invited to write a series of articles on Solar. My reward was the pleasure and being asked to do so.

The article is flawed and could be improved. But it is no less valuable. I've not looked at AC units for some time and to find another couple of DC units is worthwhile.

I do question the swamp cooler. It seems quite pricey for what it is. But then, growing up a bottle of coke was only a dime (or 5 cents at a school dance) makes me frugal.

Kayteg1 you are being a bit overly negative on the value of this article. Of the 5 units listed, I only was aware of just 2. The other three were options I had no knowledge about and actually find to be very interesting. Sure, it wasn't an in the weeds article that one could geek out on the numbers but I don't think that was the point. Unless you are willing to do the legwork yourself to get the level of detail you want, don't knock others for the effort they put in themselves. Any information is much better than no information.

Also, your first hand experience with the amperage draw though a valuable insight doesn't make the article wrong. Possibly what is happening here is the amperage draw being reported is the starting amperage and that is always higher than the running amperage. Manufacturers have to rate their equipment on what it draws to get it running so it is going to be higher.

Are you using those Sio2 batteries yet, looks interesting.

valhalla360 suggested the chart.

With covid preventing me from picking them up--and income in a nose dive for the same reason, I'm going to wait a year. I may do massive solar first as well.

The Dometic Coolaire 2000RTX really looks like the best solution for Truck Campers and will be at the top of my list...

"19.5 amps DC in the Eco mode and 29 amps DC maximum"!!!

That is incredible! Sure, it may not keep up in 120F weather but 100F weather looks like it will be just fine and that is what we experience 99% of the time. Couple this with some good solar and some nice LiFePo4 batteries and you are set for most situations.

Granted the expense of $2800 is a lot more than the RecPro or the Coleman Mach 8 but I think the performance is worth the cost for my personal needs.

Thanks for the link.

Mello Mike is one of the good guys imo.

Keytag is right about having a chart. He often offers good advice.

Let's just ignore Keytag

Nice article. It did not seem to intend to be a comparison chart between each unit exactly. It is an article about different AC options for the TC crowd. Good info. Most of these I have not heard of, so now I know.

The DC units intrigue me in that they run without a generator or hookups. Given enough solar and battery you have AC while in the boonies without daily gasoline refills... IT states amp use, but that is when the compressor is running, so the calculation would be based on what % the compressor runs and then how many amps just the fan draws. 300 amps of available battery and 29 amp draw would give 10 hours of use, but in reality the compressor cycles so it could be much more. Enough solar on the roof, the entire roof, and sun and all is good.

I dont have the space on the roof or the desire to deploy ground panels, so maybe the next RV for me....

Very lousy job comparing.
RecPro 9.5 is listed as taking 12.6 amp, when actuall measurements are about 1/2 of that
Somebody got paid for promoting certain brands?

Mello Mike is a personal friend of mine and he received NO money for writing this article. So your cry's of "someone got paid" are unfounded and stupid!

The 12.6 amp is directly from REcPro website
