The main issue though with the bigger units is that they need to intake outside Air and exhaust the hot air and often do so through a combined hose or in a way that merely reheats the small hot space inside the RV.
There are RV sites all over that talk about this at length and I would suggest finding a site where your unit is discussed and asking people in the exact same unit what works for them.
I have a Casita Camper for example and what works in them might not work too well in a Stick Built Metal sided unit.
More actual details about your rig would help others help you here.
Yeah, in the ‘portable’ (wheeled) ones you definitely would want a 2-hose unit. I tried a 1-hose A/C in my little trailer and it just sucked hot outside air back in through cracks or whatever just as fast as it produced cold air. Room air conditioners from 5000 BTU on up tend to work too if you get the right size for the space.
Is this for an RV or a tent? If a tent, I’d just get a 5000 BTU room unit and zip the doorway around it.
Anything that actually works is going to weight about 60 or 80 lbs at least. No getting around it. And some that weigh that much don’t work… I tried a portable mini-split called Rollicool and it was a total fail; it only dropped the temp in a 14’x6.5’ trailer from 89* to 83* in the course of an hour, so I returned it.
I’ve never met a backpacker with a portable air conditioner.
You might do better using a goat or mule to haul it and the battery pack and solar cells.
I’ve taken rolls of aluminized bubble wrap —- Home Depot attic insulation —- for car camping to put up inside a “shade” shelter against the mosquito netting walls and on the roof in hot weather and it’s very good at blocking direct heat from the sun. Unlike a cloth tarp, no noticeable infrared comes through it. The kind with aluminum on both sides works best.
It at least needs a long hose carrying heat to a heat sink in the nearby ocean.
And in a tent, dumping the heat through a hose?
This is where the Reflectix aluminized bubble wrap would make sense, to block sunlight from heating the tent:
But for catsake, that thing is probably barely competent as a beer cooler.
Not to mention likely using an ozone-destroying refrigerant, for which China is currently the primary source.
A portable (one that can be carried) A/C that uses refrigerant doesn’t exist. The basic components of this type of system are evaporator-aka cooling coil, condenser, compressor; plus other components that control the flow of refrigerant; and the amount of electricity required would require a very large battery.
There’s wouldn’t be enough surface area of the coil to develop any useful amount of cooling in a unit this small.
The closest you could get is one of those that roll around and exhaust out of a window; I think Frigidaire makes one. portaable AC
I flagged it. When they dredge up a thread from 3 years ago on their first post and make a spammy pitch and give a link to buy something I don’t usually give them the benefit of a doubt.
I had a great results with homebuild ac few years ago, our central ac was being fixed that summer, (our electrical was already over loaded with few windows ac running) it was basically a large cooler, filled with ice, an old bmw heater core, a 12v submersible mini pump, and 2x12v 120mm fans. and few sheets of hard foam insulation, pink 2x2 sheets from home depot. worked better that i expected, but not before i discovered and corrected few mistakes. i made it to run on 12v on purpose so i can use it in a tent during camping, while it worked great at home, camping use was not that great, i mean it did work great as long as there was ice in the cooler. but cooling a tent in a summer heat is very hard (barely felt that the cool inside the tent) and it made walls and some stuff inside the tent go damp. So now i put my tent in shade as much as i can, and if not, i cover it with emergency heat blankets, so it reflects ir rays, it works better than ac.
For some of us, our idea of “camping” is staying at a hotel which lacks a restaurant.
Don’t get me wrong, I’ve stayed in some remote locations, including one wherein the hotel probably had the only electricity for a good 50-100 miles, powered by two large Caterpillar gensets. It was surreal seeing wood fires across the lake while we were in full Western luxury with aircon.
