Thread: I've gone and done it.

Not sure Marcus, in the middle of each side of the bed is a pod, a booster fan within the air con ducting I think. I think I'd rather bump my noggin on a flat bit of plastic than a non-forgiving steel box.
I'm going to leave the parcel shelf above the two rows of pax seats, up the front.

Paul, I'm thinking air con at present. Would it be feasible to get a split system and plumb it into the existing ducting for the engine driven system? What power requirements would be needed for 40' x 8' x 8'?
The existing ducting runs along the floor and above the windows, with outlets at each seat.
I may need to boost the new unit with an auxiliary fan, maybe the type in kitchen or bathroom window extraction fans.

I had a split system in mine, worked well, but was not ducted. During the start of the refurbish, I bought a new split system for it with the plan to duct that up to the bedroom. I guess if you already have a system in the bus, you should be able to plumb a new/extra one into it as well.

Hey Paul, are you ignoring me?

Oh no!! You scared Scary.

Hmm,you called?

Probably as someone said,a wall split system would be the go,but you would have to mount the outdoor somewhere,or go for a roof top caravan style all in one unit,but then you have the problem of weatherproofing the penetration and it would stick out a bit above the roof level outside,around 350mm at a guess.

The roof top is the best option as they are designed for auto use,but due to the size of the bus you may need two,or if you only want to do, say the bedroom area only,you need a way of shutting the bedroom off from the rest of the bus.

The other problem is two units may overload the wherever the site power is coming from.

Plumbing into existing ducting would probably be too difficult,you would need a ducted split,not the more common wall split.Difficult to configure the ducting i am guessing.

Hope the above is not to confusing.

Around 29 square meters,floor area,if using during day,in hot weather and bus is in the sun,maybe need around 6KW,if only at night,5KW.

The other thing is any wall type split will have no warranty when in this type of application as the copper pipes love to fracture with vibration.This is another reason why the caravan style roof top suits the job better,but i haven't had much to do with them.Many people use the split systems,and they seem to survive,but some fail,i have fixed a few in motorhomes.

Earth to Rick130....may have some ideas as well..

What about a couple of caravan systems and cover the rest of the roof in solar panels to reduce the effect of solar heating. Bonus charge for the batteries as well. Down side is: You'll never get it into a shopping centre car park.
