The new climate denial? Using wealth to insulate yourself from discomfort and change
Alexa! Please set the room temperature to 72F… Would you like that in degrees centigrade?
Sorry, I can’t hear you! I’m making too much cooling noise!
Alexa, it’s too hot!.. I stopped cooling so I could hear you better! Totally not to send that data to Google for precessing.
Alexa… Google…
Are you implying what I’m implying?
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.
wow a shocking amount of people here have no idea how AC works
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.
Let me fix that for you. A shocking number of Europeans have no idea how AC works.
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.
Maybe invest in a reversible heat pump so you’re ready!
I wish; I rent, so it’s whatever they’ve given me - specifically a window unit currently.
I have just one thing to say: 🖕
So you volunteer to fund one for me and convince my landlord and the mayor to allows its installation ?
Don’t forget you need the compressor installed outside too!
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)
Which is why most people cant get one of these because their landlords are shitheads.
They make portable minisplits now.
„Nicht verfügbar“
Yeah with the current heatwave that’s to be expected. Just get one during fall or winter, and be ready for the next year.
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.
Yeah those are much more common and way cheaper, but also much less efficient.
I see, like a heat pump.
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
? It is a heat pump
Heat pumps are like heat pumps
Have you tried not being hot?
Heat cannot legally enter your body without your consent.
This is why we need “yes means yes”
If it’s legitimate heat, your body has ways of shutting that down.
this is it. they’re trying

They make my 2 fav things: air conditioners and the lancer evo final
Evo VI TME needs a word.
Source: I am old.
Oh that one can have a word with me anytime! Honestly id be happy with any Lancer
Any lancer or any evo specifically?
Because the standard lancer is pretty boring
My dream car (that i could most realistically get) is the Mitsubishi Lancer Evolution Final Edition 2016. I love Mitsubishi’s transmission and there’s just something about how the Lancer Evo Final looks. I love rally and ideally i’d love the Mitsubishi Lancer WRC (or anything from the Group B Rally era lol)
What is that?
Its called a heat pump or mini split. Really well made system for air conditioning.
Becoming more common in the states. Rest of the developed world already uses them.
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.
It is in fact literally the opposite of central, aka decentral
I consider these superior to central air due to its ability for zone control.
Got you, a fancy cold-blowy box :)
I think I’ve seen one of those once in an office somewhere - though I feel like that one blew out warm air instead/as well (I may be mistaken).
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.
That’s not just a fun fact - it’s a useful fact :)
Billionaires who want to boil the proles alive hate this one trick
I’m going to leave this running and open the Windows for a little while. Hope that helps all you folks out there.
Why don’t we solve global warming that way? Just put a bunch of A/C units outside and turn them all on in the summer! (/s, obvs)
How considerate. For instance, my friend’s Internet went out today. I mailed him a cup of Internet, he should be good to go on Monday when it arrives.
A whole cup, eh? Make sure he doesn’t spend all that internet in one place!
You’re doing gods work sir
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.
Your house isn’t that air tight rofl.
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?
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.
There’s ductless mini split units that bring in fresh air?

Comment deleted because it was a load of nonsense
LOL! I was just about to “well, akshually” you about minisplit design!
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.
one window slightl
Bad solution. Like in winter, open the windows fully and exchange all the air when needed. A slightly open window is very inefficient.
I can have the windows closed all day with no AC and not worry about rising co2 levels
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’re probably thinking about carbon monooxide, not carbon dioxide?

You’re right I was wrong about that, sorry lol.

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

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…
I’d suggest running them with windows open if you can afford it.
With that attitude you can also justify private jets. It’s obscene to intensify global warming unnecessarily by wasting energy like this to escape global warming.
Surely that emits a lot of bad stuff into the atmosphere especially during a heatwave? Can’t be very good for the environment!
It works similar to a fridge with the inside of the fridge being your apartment and the outside being, well, the outside. All it does is circulate air over a heat sink filled with a refrigerant, which never leaves the system; it does not emit anything.
The fact that the power it uses comes from burning fossil fuels instead of green energy is really not the consumers fault and is part of the reason why the demand for these devices is skyrocketing in the first place (It’s getting hotter because of the climate change)
deleted by creator
Sure, but the inside and the outside of your house aren’t different universes, the heat that your fridge emits still gets out into the world. Dense urban areas with widespread AC units can indeed be slightly hotter than if there were no AC’s. We’re talking in the ballpark of 1-2°C. That shouldn’t be a big issue for the local environment. And that heat is not what’s causing climate change. Climate change is caused by greenhouse gasses, not by heat-emitting electrical devices
Eh, technically both contribute. Heat from electrical devices still gets dumped into the environment, and a good portion of that electricity is produced with greenhouse gasses (coal or oil-fired power plants).
Generally, though, yeah, the heat from running AC (or, say, a desk fan) is miniscule compared to other factors.
The heat from electrical devices are basically negligible compared to what the sun beams into the planet, otherwise solar panels would be physics defying.
The problem has always been greenhouse gases causing the sun heat to escape slower than we collect them.
Your phrasing of “a lot of bad stuff” sounded like you were saying that AC puts out chemicals or something.
No, but many air conditioners make racist social media posts, aggressively catcall female passerby, and support child marriage.
I mean the electricity which powers it does. The unit itself does not, unless it was installed with a leak, in which case it won’t work for very long.
Lol
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.
Nah, one way to think about it is that by having a lower melting point, it “holds” more of the cold from the freezer.
You’re wrong, look up old school ways of making ice cream. Ask an old person if they remember biting into a salt crystal when having old fashioned ice cream.
Great. You’ve got a hypothesis. Now work on it this weekend and report to the class on Monday for a practical.
Much colligative
