Aircon for Coaster bus

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.

Have you looked into the viesa units that they use on trucks, I'm not sure how much they cost but there was one in the truck that i used to Interstaters in and it worked to bloody good,

Where are you located? I have an air engine driven aircon of an ambulance you could have cheap in Melbourne. Eric

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.

Hi Eric,

Unfortunately I'm in Perth, thanks for the thought.
