Can anybody help, I am setting up a mobile home.

I am looking for an aircon for a 2001 Toyota Coaster bus with 1HZ diesel motor, electrics are 24 volt, prefer 24 volt system that can operate on the road and when camping, I searched google and found Comfort Air/ Breeze air 12/24 Volt, but far too expensive- I was qouted $7000 excl fitting.

A 240 volt system is a problem because a 24V-240V inverter 3000w costs about $2500 on its own.

Any suggestions welcome for an affordable unit.

Cheers

Puttputt,

Engine driven options should not be a problem, but running a useful sized air conditioner from battery power really isn't feasible - far too power hungry. You refer to a 3000W inverter - no way can a reasonably sized battery bank supply power at that rate (way over 100 amps) for long enough to be useful.

Probably the most cost effective way to have air conditioning while stationary is to use a generator to power a 240V unit (much as I dislike generators). This would have the advantage of simply running off the mains when that's available, and no doubt the generator would find other uses too.

Thanks John,
Actually I need to make a correction, I would'nt need it to run on batteries alone, only with engine running or 240V AC back up, in other words, when driving mainly, but with option of using at a powered site in a cp, will also have curtains to help with solar affect.

If you care to post your email address (disguised) I have something that may suit.

I think maybe you are hoping for a unit that does two things. i.e. aircon while driving and then aircon when stationary.

Put simply... you can .... but need to have the motor running all the time!

The only other alternative is to have a separate 240v aircon. Built in caravan version very expensive. A portable refridgerted unit would do the job if you have the room to carry it. Theyre going cheap now that summer has passed.
