    Unfortunately I bought a portable unit for my room. My reasoning, rooms gets to 38c and sleepless nights could mean sleeping through alarms, future health concerns and also, this heat won’t be going down any time soon.

      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.

      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.

    Hey one of you finally realize that air conditioning is necessary to sleep at night when it gets really hot, a problem which is only going to continue to grow worse thanks to climate change. At least until the ocean conveyor breaks completely and y’all start freezing your balls off like you live in Siberia.

                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.

      Central air conditioning, but designed better. It services individual rooms instead of taking the temperature of the entire house from one location and then distributing based on that.

        That’s not what central air conditioning means. Central air conditioning has forced air ducts and a single chiller unit. This is called a mini-split or split unit system.

          Fun fact about air conditioning units. They are basically a glorified heat pump. And many of the newer units that are being produced can pump heat into the house as well as pumping it out of the house.

    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.

        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.

    Beware that those things do not bring fresh air in, so if you close windows shut the Co2 levels would rise rather quickly and elevated co2 levels are linked to decreased cognitive abilities. I’d suggest running them with windows open if you can afford it.

    EDIT: Whoa, so many downvotes and arguing. Guys, get yourself a co2 meter. You will be surprised.

        It’s not, that’s why people dont suffocate indoors, you get tiny bit of fresh air in, a tiny bit of stale air out, so it has to stabilize eventually, but the level at which it’ll end up will definitely be in the impairment range. Brain fog, fatigue, heavy breathing, trouble concentrating, that kind of stuff.

      Oh yeah? Then what do you do in the winter? Your heater doesn’t bring in fresh air either. Do you keep the windows open and let all your heat out?

      Also what other air conditioners are you comparing against? Because window units also keep the air compressor outside the window with a barrier between the inside part, which takes in air from the room.

      All HVAC systems recirculate the inside air, without bringing in fresh air. So please elaborate on which cooling method you would use during these 30°C/100°F days we have to stay cool?

        You’re wrong on that one. Ducted air conditioning systems do bring fresh air in, as well as positive inflow and heat recovery ventilation systems.

      I don’t understand your statement. I can have the windows closed all day with no AC and not worry about rising co2 levels. Why would it be different with this device running and circulating air? It’s not like it emits co2.

      This looks like a wall mounted monoblock so you would be right but if it’s a split device with an outside unit, it does actually bring in fresh air. This is wrong, split units dont bring in fresh air either. The only setup that consistently brings in outside air is a monoblock with 2 ducts. Either way, I’m pretty sure running an AC with the windows open is never good advice even if you can afford it.

      The only point of concern would be if you have a gas heater for water etc. in your apartment and run a monoblock AC with just one exhaust hose blowing hot air outside while sucking in new air from the inside. In that case, the negative pressure created by the AC can potentially pull gas that would usually go out the chimney into your apartment.

        CO2 always builds up in the room with no airflow, and when jt gets above 1000 PPM it starts causing fatigue.

          And how exactly does an AC intensify this issue? Because lets be real it’s not really a problem people usually face in their daily lives. Some people leave their windows closed for days during the winter (Which is also bad because of mold etc. but thats another story). Most places are not nearly well insulated enough for it to be a problem. And if it was a problem, having an AC device or fan that circulates the air and evens out the co2 levels across the house would actually help alleviate it somewhat

            It doesn’t. They said “if you close the windows”, although leaving the doors open and opening one window slightly will get CO2 down significantly.

        That’s the thing about co2, you don’t really notice it unless at extreme levels, but it definitely affects you, at pretty much all levels.

        split device with an outside unit, it does actually bring in fresh air

        That’s the common misconception. The lines running between minisplit units are for refrigirant, not air. It’s essentially a fridge without a box, with the room where theyre mounted becoming the box instead.

        Why would it be different with this device running and circulating air? It’s not like it emits co2.

        It doesn’t. It’s just that people who run AC’s usually shut everything closed and then exhale all that co2, which in an ordinary room with just 1 person in takes <1hr to reach noticeable impairment levels. AC or not, ventilation is important.

        The only point of concern would be if you have a gas heater for water etc

          You might be right but I am certainly not opening my windows once an hour during winter, if that’s the standard then we’re all screwed by the time we go to bed with the windows closed. I don’t think this problem is significant enough to justify running an Air Conditioner with the windows open…

          You’re probably thinking about carbon monooxide, not carbon dioxide?

          Yes, I am. As that is the only “real” concern I see with AC’s and gas buildup. As I said co2 is just not a big enough issue to justify not getting an AC or letting it run out the window. Regularly airing out should be common sense, but I think once or twice a day is regular enough for the average apartment

I don’t think this problem is significant enough to justify running an Air Conditioner with the windows open…

            Just to be clear, I dont mean wide open, just a litte slit to let some air in, which should be totally enough to keep levels below 1000ppm. If you’re just airing twice a day you get to 450-ish briefly but it jumps back in an hour or two and you spend the rest of the time somewhere in the 1500-3000ppm range. And I feel that about winter, yeah, it’s either warmth or fresh air, gotta choose one. Not even heaters can spare one from annoying cold breeze. But in summer it’s at least avoidable. Whole point is, even right now where I am, whenever I go anywhere, I see AC’s set to some stupid low settings, like 18C or lower, so the places are colder than they are during winter, but the air is so stale I feel like I could swim in it, which is arguably even more wasteful than running AC straight out the window. But it’s so hard to get the point across to people, especially the oxygen-deprived ones inside those places…
