De'Longhi - Arctic Whisper Extreme PAC EX398VUVC Portable Air Conditioner with UV-C technology and Eco Real Feel

I got a good AC from the Italian brand DeLonghi. Also got another one from Ayce (do have split level apartment). The DeLonghi one is the best of them two.

I quite like my De'Longhi, even though it's bloody loud. But if it means my home office can be usable on hot days, then so be it. Noise cancelling headphones are the solution.

Pinguino crew big up!

Yes, and I recommend buying one second hand in the cold months. Pinguinos and suchlike, used a few times selling for 75 quid on t'ebay

Mine is a DeLonghi Pinguino. Had it about 4 years and no complaints. https://www.argos.co.uk/product/9453490

Yes. We use it in our living room which is quite large and open and it's great. The hose goes up the chimney. If you used it in a single room it would be Arctic-like which I'd love 😄 I would say it isn't noisy but not sure others would be able to cope with it being on. It's a similar level of noise to an airfryer, imo.

Buy a delonghi pinguino, adapt a second tube ( intake ) to don’t suck any cold air from inside to cool down the compressor! Place near a window, tubes outside, and find a way to isolate so no hot air comes inside! If u need some tips, i can show you my setup!

We used a portable refrigerative air con temporarily (with removable window kit & tubing), which did the job for the master bedroom when we had a newborn (waiting on the ducted installer).

Pretty sure ours was a Delonghi, but this was many years ago - so there could be better options out there today

Got a couple of delonghi pinguino ones and they're really good. Upstairs one cools two fairly decent sized rooms to a nice chilly temp and one downstairs chills the open plan downstairs and while it's not freezing (the poor AC unit isn't designed for this square footage...) it makes a pretty decent dent and brings the temp down alot. Would recommend.

I have a delonghi too, do you ever empty out the water?

I have an old mobile RC unit from my time in France, no name brand, model is not even available anymore and a colleague from work tried one recently from Delonghi(she's returning it because it was way too noise, like I told her). From my experience all of them are loud, over 65 DB due to the compressor, no matter how the company sugar coats it(Delonghi said their is 62DB, still way loud and I bet you it gets to more than that), it's a very very loud refrigerator at the end of the day Second point : you need to either find one that has 2 exhausts or convert one to have 2 of them. Reason is efficiency, manufacturers nowadays do not make mobile AC's with 2 exhaust because it's cheaper, so you are stuck with the one exhaust and should convert it to 2 because the side that normally should have the second exhaust is the compressor side and this side gets very hot. So think of it like this, you want cold air and have something that to get cold air create also a lot of heat and manufacturers being lazy and cutting costs said ok let's have the hot stuff be cooled by the ambient air that you the user want to cool. I just DIY-ed a second exhaust and put some heat tape where the rest of the holes were. AC has been going strong for 4 years now so no I did not damage it and it's well out of warranty now and the compressor also has a fan from the manufacturer so it pull air already, I just made it so it's more efficient to cool the room. Third point they do not cool that well, I set mine on 16 and in a 30 sqm room it barely drops to 22, it's a 9000 BTU unit so based on this and what I seen a wall mounted unit can do it should drop down easily to 18 but no, 22 is it's limit, which is still pretty comfortable if you ask me. Forth thing you will need to figure out how to constantly evacuate water from it because the included reservoir is good for 20-30 minutes, then it will stop until that water is evaporated, so get a hose and see where you can evacuate it without much hassle. Fifth point you will need to put it in a location where it evacuates the heat meaning you will have to find a place for it next to a window or a door that needs to be sealed off well, if you seal it well you will see that the usually included zipper blocking wall will inflate towards the outside or inside(can't remember now), this is due to the pressure difference from the inside to the outside, for me this is a good sign you have made a well isolated air conditioned room. There is now a better alternative, pricier but I do not know how it works in the form of a compressor positioned outside and a fan inside, like a traditional wall AC, Midea Portasplit it's called, no idea how good it is or how it works but the principle behind it for me should result in less noise, better cooling and even less electricity used.
