Another air conditioning question.....

Post by captxmas » Thu Jul 09, 2009 8:24 pm

Has anyone seen or tried the Dometic brand 24volt air conditioner. If so, how well does it work and where in the US can I find one. I've been shopping the net for info on sales and can't find a dealer. Is it european only?

It seems to be similiar to the units used in RV vehicles and self contained as a roof mount.

I appreciate any input you have to share.

Try DC power solutions !

- it is another 12/24 volt AC that is in the USA - the military was using them and I was going to get one but the $3 to $ G thing made me buy a Carrier low profile to get going with my already owned inverter.
They are supposed to be far superior to the DCAIRCO's!

I may still buy one depending on how the inverter/Carrier works!!!!!!!!!!!!! :shock:

My math had the 24V air conditioners in the area of scary as far as current draw. Their rating (that I found) seemed to soak up a LOT of the rated output of the alternator, and searching the forum revealed no larger alternator available, just the possibility of getting a good alternator shop to rewind it for a bit higher output.

Now, that said, I'd *bet* that the rating on those units is on the high side rather than the lower side. I don't think it was high enough to be peak draw at startup, but you have PLENTY of battery power to handle peak draw at startup (as long as you give it sufficiently large wiring to the battery). Assuming that, it would probably work, at least as long as your alternator is in tip-top shape.

I may be inclined to try it (unless someone beats me to it and reports that they don't work), but if I do I'm gonna carry a spare alternator on any trips just in case, too. It's definitely a large enough additional draw that the alternator is gonna know it's there.

Rewinding the alternator works out to a 15-20amp increase in output. However if you go above 50 amp it may not charge as well at idle speeds.
