This question is for those folks with practical experience in refrigeration.

What would be the practical problem(s) with the following:
  • take an off-the-shelf A/C window unit like can be found for a couple hundred bucks at a home store
  • recover the refrigerant
  • split the system in two
  • relocate the compressor and condenser, etc to a well vented location under the bus (add a fan).
  • relocate the blower and evaporator to the inside (add in some nice tinsmithing/fiberglass work)
  • reconnect the system parts with added copper tubing and condensate drain
  • recharge system compensating for additional volume
  • voila! Custom mini-mini-split A/C for only a few thousand dollars and three years' labor!

I really like mini-split systems, but I'm too cheap to spring for the real thing. Plus, it might be fun. Plus, if I did a good job, it would look very nice, and be quiet. And yes, I know that it isn't going to save me a lot of money like the Geico lizard.

I have seen an A/C unit that was a window type in the bay. It was ducted up into coach. It was operated by a remote control. He had 1 in front area and one in back. The wireless remote operated both units. I worked well in the Texas badland of Terlingua. One thing , his generator was 220.

Via floor registers? why not? Can't beat that for simplicity.

The ones I saw were in a scoolie. I just checked on one of the scoolie boards, and there are a lot of them doing it. The young man that had shown this to me is a Satalite programmer an travels the US. His name was Shawn, and he was much more into the electronic aspecs than I could absorb. I wish I could find him. He did duct up eye level with additional fans like in computers. As an aside, his interior was a yayct
that was being scrapped in San Fran. Really neat.

been doing it for years using 120 volt 14700btu units 2 in the front and a 10,00btu unit in bed room use bays for return air. Makes a quiet/ less expensive. Ac solution. I do use a ceiling fan to bring heat off ceiling to aid in circulation-it is mounted above drivers seat. $45 20inch diameter from Lowes. Bob

I was considering placing a window unit in the spare tire compartment under the driver of my Prevost to replace the "dash air" that does not currently exist. I quite considering it because several said that the units would not last long because they were not made to take the vibration of a moving vehicle. Was I lead astray and it is still a viable thought?

Rob, I've been using a 12K BTu window air in the back of the bus for 6 years. It cost a grand total of $150.
My bus is spring ride, but a couple of years ago I put an auxiliary air ride system on the back end.

Maybe it will shorten the life of the AC unit, but come on, after 6 years and about 68,000 miles?

Rob I just put the condensor unit for the mini split 12000 btu there in the 98 the compartment is almost 30inches tall under the floor landing. next to the driver. I made a access hatch from above. you could probably lower a window ac thru or just get a minni split Had to relocate heater lines for defroster to side. no big job. bob

room to put evaporator on top of box for defroster if you use mini-split and blow out dash. I put above driver in overhead console. Bob

I find it interesting that people say window or mini split ACs won't take the motion, yet many say that a 120vac home type refrigerator will work just fine. They have the same basic components.

Hi all, I thought of using a small house window unit in the area next to my engine air cleaner to provide cool air to the engine. I have a MCI-9 40FT I think there is just enough room in there for one. Any thoughts would be appreciated,

Buying two-splitting to make one has been done and successfully. Go for it!
I'm using 15,000btu Dometic Penguins in the basement. Penquins are the only roof top A/C that uses a squirrel cage blower for the condenser that can be ducted. I'm using the ducted unit. I found out from Nick that the 15,000btu is actually a 13,500btu unit with just a bigger blower-which is perfect for ducting. I'll let you know how it works out. Good Luck, TomC

Tom...could you elaborate a bit on these roof units(so I understand) in a "basement" configuration? More or less as Cullen described?

Also, you are saying then, that the advertised 15M units are ...not as advertised? I note they show both 13,500 and 15,000. Interesting!

Thanx
RCB
