You'd be surprised (I certainly am) how fond can some people be of concrete box architecture - hint Le Corbusier.
Take a look around [1]. This is what every neighbourhood built looks like now. [1] https://maps.app.goo.gl/bMYANpDU2AGDKVQN7
We have those stupid regulations in Finland about how the outside of our apartments buildings should look - meaning you cannot put the condenser visibly on the outside of the building. I've heard stories of residents being scalded for putting flowers on their balcony railings that face outwards as it ruins the "look". Given almost all apartment buildings are built consistently between every floor they could ensure co…
You say stupid, but I actually would find it sad to see beautiful buildings that are in many cases hundreds of years old defaced with loads of small condensers bolted on to the face. That doesn't mean they shouldn't have A/C but rather all flats use one system with a large roof condenser, or where that is not possible district cooling or ground source.

Forced air cooling require air to be colder than the heatsink surface and evaporative cooling require relative humidity to be less than 100%. I don't know how bad the situation in Europe is, but we're already at point where there are times and places on Earth where one can construct a primal instinctive understanding of that by simply walking out of an air conditioned room(to which you SHOULD return within half an ho…
> I don't know how bad the situation in Europe is Yeah there are those places, and northern Europe is not one of them!
The WHO guide others are posting says fans only work under 40C, but that's the absolute maximum. There's no other option than resorting to devices based on refrigeration cycle when people are already dying("estimated through excess mortality" or however you dress it up), beyond being useless(human cognitive performance significantly degrade at above 28C).
The upper bound of 40C quoted in other comments is also just absolute maximum temperature - it's just saying that there's no way fans do anything if temperature of air and body are actually equal. The practical upper bound is lower than that(humidity and metabolism dependent, I guess).

haha. no. try opening your window in +15C high humidity and then sleep. I assure you, sleeping in a 0-5C sleeping bag on the nearby sea shore would be a more acceptable experience. You just never lived there, yes?
Perhaps 15C is a typo? That is perfectly comfortable even at 100% RH + no air movement.
For me the hardest part is sleeping. I can cope with heat during the day, but even with good bedding, mattress, windows open, fans, etc. the body traps heat underneath and if it's hot outside it's just impossible to sleep. I was like a zombie for 2 months this year. And sleep deprivation in general has a ton of adverse health effects. Unfortunately, I do live in a "heritage" building so split unit is a no-no. Midea p…
They're back to normal prices now. At least in Germany. Make sure to grab one before the next Summer hits :)
I also find deeply and even extremely ironic, that the same greenwashing radicals who bash ACs in Europe are then supporting "heat pumps" as a modern and efficient heating device. There are even programs labelled as Eco or green or whatever the jargon of the day is, to subsidize or finance heat pumps. People are seemingly unaware that heat pumps are just an AC with a tiny additional valve in the pipes :) .
Heat pumps are just ACs with a lot more energy efficiency. How does that make people hypocrites?

> ...Each year? Was it the case every year twenty, thirty, forty, fifty years ago? What has changed, miss Follett? Are you considering answering this question? Was it the case fifty years ago? Did anything change?
And if you don't already know it, just wonder why AC isn't widespread in Europe, why nuclear plants built decades ago have to stop due to the lack of water and why every single article talks about an "exceptional" heat wave. Do you really need me to hold you hand there?

How are u gonna punish china? do u have any logic? chatgpt 3.5 makes more sense than these types of comments...

While I hear you, I think AC is better centralized for the building, along with heat and water. Yes, there are numerous reasons why this is harder to do than just doing it ad-hoc per apartment, but if we’re to see it as infrastructure, it should receive the same level of consideration as other utilities.
For most of the buildings from communism era - all the utilities run through the apartments anyway and there is absolutely no place or way to retrofit these utilities without extensively either re-doing it from scratch, or trying to somehow retrofit it on the outside. All of these options are a non-starter considering basic AC starts from $500. Why should anyone invest more than that?
