Mumsywumsy was not a happy camper this last weekend, only one air conditioner that wouldn't stay running in the day time because it would overheat and shut down.Just trying to cool the bedroom. For a number of reasons I don't want to use RV roof airs. I have pretty much decided I want to go with mini splits, unless someone really has a compelling reason not to. I have space in the front to mount one compressor unit and a number of possibilities to mount one in the rear.
Is lower cost to run the inverter types the only reason to buy one? Since it will only be run when I plug into power that I paid a flat fee for at a campground, what makes the difference?
My understanding is that they run all the time, just at different levels, do they always put out cool air just different amounts? That does seem like it would be a plus. If so that answers the first question.
Just as a rough guess would two 9s cool this,
should I go with two 12s? Mounted on very front and rear walls. Forty feet long, rough R values are, walls R6, ceiling R3, floor R10?
I have found this,12,000 Btu Klimaire 15 SEER DC Inverter Ductless Mini Split Heat Pump Air Conditioner. I can get two with installation kit for $1400 including shipping. They are the inverter type.
It seems that you can get a higher SEER number in a 12 but they are 220V.
Just for the record the unit I have is the exact same one this guy is selling. (didn't buy it from him) I had used it in my semi, I took it out, and basically had done the same thing before I even saw this. busconversion101.com/air_conditioning.htm
