        Splits are unreasonably expensive, and since there is now a compressor sitting somewhere outside and a bunch of piping, more stuff to maintain/go wrong. I remember buying my condo and seeing the split and thinking how convenient it is, but little did I realize after ten years the whole thing would need replacing. For what it cost, I could buy a new 5000 BTU unit every year and throw it out and break even after ten years.

                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…

                  while preventing outside air from getting in

                  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.

                  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.

    Here in the USA, south Mississippi, it’s fucking hot as hell as well!

    And unfortunately, we’re borrowing my mom’s car for now, waiting for a part we ordered for the truck to come in. Mom’s car has 4 windows, but only the front passenger window goes down, and no air conditioner… 🥵

    I’ve taken to bringing a cooler with us, with bare minimum of 2 bottles of frozen fresh water, plus 2 bottles of frozen saturated saltwater.

    Why frozen salt water? Well it’s definitely not for drinking, that’s for sure. But frozen saltwater freezes at like -10⁰C, which makes them excellent ice packs to keep things in the cooler extra cold for around 6 hours or so…

    Stay cool out there everybody!

      I think the salt is actually worse for keeping thing cool longer.

      Most of the cooling capacity of the ice is in phase change from solid to liquid. The salt is moving it to -10 which means bigger gap from outside temperature. So the cold escapes quicker.

      If you use normal water it will climb to 0 faster, but stay there longer.

        Air conditioning is literally just moving heat from one space to another even at scale the air conditioning from homes is not enough to make any meaningful difference.

        Now if we want to get pedantic the stress that it puts on electrical grids that are not decarbonized and have to fire up natural gas and coal plants harder sure it is technically making everything else hotter

          So if we ignore everything but the actual physical heat coming out of the radiator then yes, it’s really not that much, but unfortunately these units do not exist in a vacuum, and instead contribute to 3% of global emissions.

      You can always plant more trees, paint all the buildings brighter colors, live underground, or move north?

      https://en.wikipedia.org/wiki/Passive_daytime_radiative_cooling

      PDRC can be contrasted with conventional compression-based cooling systems (e.g., air conditioners) that consume substantial amounts of energy, have a net heating effect (heating the outdoors more than cooling the indoors), require ready access to electric power and often employ coolants that deplete the ozone layer or have a strong greenhouse effect.

      Yikes.

    Pretty spent this heatwave with a damp cloth wrapped around an ice pack and stuffed under my plums. Working from home is no fun when it’s 35C in your room. I even stole the cat’s cooling mat at one point (she hated it anyway) to use as a pillow.

    I installed both AC and solar panels when heat got too dangerous for my kids.

    Yes, many everyday problems can be solved with money, money were literally invented for that exact purpose. Other problems can be solved with time, for example - trees need a fuckton of time to grow, but I still replaced most of the grass in my garden with trees and bushes. I will most likely never rest under their shade in my life, but is that really important to see the benefits fast?

          That particular quote is from D. Elton Trueblood. Mark Twain said “The best time to plant a tree was 25 years ago. The second best time is now.”. A bit different twist, but the same idea.

          There’s also (alledeg) Indian proverb: “Blessed is he who plants trees under whose shade he will never sit.”. And many other variations of the same over the last 300 years or so.

      Portable units are serviceable. Not nearly as good as split airco units but you can make them better by adding a second hose.

      The air inlet for cooling the compressor needs to draw air in from outside instead of from the room the unit is in.

        Portable units are absolute shit. For a little more you can buy a split like the OP’s picture, that is an Air source heat pump, which is 3 to 4 times more economical to run than any other heat source. Plus they can run off solar panels, if the roof is yours.

          Thing is if you’re renting you don’t really have the freedom to install those units. And since AC is only really needed a few days per year it’s good enough.

          I’d also much rather get the one from the OP but my options are limited.

      It makes the air cold. What’s there to understand?

      It makes the room cold unfortunately to make the room cold you have to whack a sodding great hole in your wall. You explain that to the landlord who doesn’t care about your comfort, but they could care immensely about the wall having a hold on it.

        Ours have a hole about 50mm in diameter. It’s not going to bring your wall down and if you decide that you don’t need the efficient heating/cooling with minisplit-unit it’s easy enough to patch. I own the house, so I didn’t need to think nothing else than the location of the hole, but any sensible landlord would see a minisplit-unit as an increase of property value.

          A sensible landlord would recognise that yes but only if they got to keep the air conditioning system. Realistically though the tenant would probably want to take it with them when they left after all they bought it. And the landlord might not want the owners to be on them to buy it off the tenant when the tenant leaves.

      It actually does require some basic knowledge of thermodynamics. Many people think “there are space heaters, so why not space coolers?” The reality is that the heat needs to be pumped out of the room (meaning hot air needs to be vented to the outside of the building).
