As far as I know they are mosty designed for vertically sliding windows, uncommon in Europe. For american style sliding windows a think they are brilliant.
That’s not really a portable AC, or even a minisplit. I am talking about a portable AC with two parts (thus called a split unit), one for the outside that dumps the heat, and one on the inside blowing cool air. They are connected with flexible pipes.
Or just portable, single unit ACs. I got one of those recently.
It blasts hot air through a duct that hopefully you’re able to direct outside while preventing outside air from getting in. Also noisy as heck, since the full unit is inside the house, and not as efficient as split units, but they do work…
If that worked you’d slowly turn your dwelling into a vacuum chamber :-)
The same volume of air will enter your home in one way or the other, the important bit is that it’s cooler than the exhausted air. In particular you don’t want the hot exhaust to recirculate back in.
Ideally you’d get medium warm air from another room into yours, and warm outside air into an unoccupied room.
Thank you. I thought I was insane because surely mobile units would have two tubes if they really needed them. Then I got one with a single tube (the only ones available) and found out that no, I am sane and these units work really badly.
Yep, main problem with those portable units is that their efficiency is pretty bad. They does work and cool the room, but amount of energy that needs to be spent, plus the fact that you need to somehow restrict airflow to not be sucked right back in - makes them a horrendous option. Better than nothing I guess.
Well yes, I meant preventing that hot air from circling back inside through the window, since these usually come with a kit to fit into the window, but aren’t particularly airtight.
Also I’m genuinely amazed at how fast that thing fills a bucket with water from the condensation, it’s ridiculous. I live near the sea so 70%+ is normal, but seeing it was still surprising.
I have mine in the living room and it pulls in air from the rest of the house, air filters in from many different places.
Rrong! The vast majority are reversible air source heat pumps, which means that they cost 1/3 to operate as heat sources in winter. Win all year round.
that’s only half of it
Shit, really? Wow, I’m on the edge of my seat waiting to find out the rest.
The electricity bill I’m guessing.
No, it’s a split ac, the other half is literally out of the picture(hopefully out of tne house)
Protip: condensers function better when its cooler. You can save money by putting the condenser in the neighboring, air-conditioned apartments.
Which is why most people cant get one of these because their landlords are shitheads.
They make portable minisplits now.

Portables are hot garbage. Get a proper air source wall split. Cheap and immensly cheaper as a heat source that anything you use right now.

Dual-hose portable ACs avoid the vacuum problem. You just need to have good sealing around the intake and exhaust hoses.

Yeah those are much more common and way cheaper, but also much less efficient.

Yeah with the current heatwave that’s to be expected. Just get one during fall or winter, and be ready for the next year.

I see, like a heat pump.
? It is a heat pump
Heat pumps are like heat pumps
They fucking better be
Yes, ac is a heat pump that can only work in one direction of cooling.
Not necessarily, a lot can reverse and pump the heat inside
