My house always is cool anyway - it’s well-insulated so heat doesn’t come in unless I open a window, and I open the windows every evening when it’s cool outside.
Air conditioning would just waste energy and increase humidity
Oh? My workplace has one of these that you fill with water that then cools the water and very slowly sprays it into the air, mixed with air of course. Works well to make the room cooler, but even in the manual it says that it shouldn’t be running all the time because the increased humidity can cause mold.
So which kind of air conditioning are you using?
(and even when it decreases humidity the other reasons still stand)
That’s not air con, that’s a swamp cooler. Air-conditioning works by the same mechanism your fridge does. And the cool coils condense water vapour in the air, thus reducing humidity.
I’m living in an area where AC is completely unnecessary. About +15°C in warm summer nights (that’s when I open my windows to let fresh air in), +30°C peak but all houses here are well-insulated (they have to be because of winter).
Of course it’s different in the USA, you have higher temperatures and don’t insulate your houses (a well-insulated house keeps its temperature: it stays warm in winter and cool in summer).
Yeah and that is my problem with them. I often get a sore throat when in airconditioned rooms, especially in smaller rooms. But it is not as bad as it used to be. Don’t know if my body changed or the ACs became better.
Lots of places in the US don’t even get to a comfortable temperature at night. Right now I’m in Pennsylvania which is pretty far north and the lowest it’s going to get tonight is 80F with 80% humidity. It was 100F today with the same humidity. I actually got sick at work from it.
Temperature is absolutely a problem. Without getting too deeply technical, a heat index above 99F/37C is dangerous even for healthy adults. Las Vegas this week has seen temperatures up to 120F. The forecast today is for a temperature high of 118F/48C (low of 90F/32C overnight), with a relative humidity of 8%. That works out to be a heat index of 111F/44C.
Where I am, today’s high will be 82F, but humidity is sitting at 90%, which is a heat index of 92F.
You can also look at wet bulb temperatures; at a certain point, your body can’t cool fast enough through evaporative cooling, and you’ll die from heat.
I lived through dry summers around 40°C without ACs without a problem my whole 40+ years of life. But 30°C with a high humidity is a different thing. Much comes down to being accustomed to things though naturally. I have friends who grew up in southern China who get problems when the heat is dry.
But people live in areas that get 35+°C every year for several month since the beginning of humanity itself.
Over night, with 80% humidity? Are you sure? I’d be close to hospital with that temperature without some kind of AC, or at the very least ventilation… (I’m sensitive to heat). And sleeping with that temperature even with ventilation is going to be very uncomfortable and not relaxing…
Also we’re talking about lows, so this is likely not the temperature inside when there’s no AC, more like 30+C
So you’re trying to say most of North America is uninhabitable? I’m in North Carolina, the temperature and relative humidity were in the 90’s yesterday. It’s July.
I mean it’s thanks to modern technology not uninhabitable, but we’re “wasting” a lot of energy to make it habitable, and this is getting worse in the future, because of climate change. I couldn’t imagine living somewhere where, I can’t get out (of AC cooled buildings) because it’s too hot.
25º during summer nights either already was or is going to become normal around gigantic areas of the world. Getting all Indians to just live anywhere else is never going to be plausible.

Air condition decreases humidity.

Also if room is too humid it stops working

Interesting, thanks.
Boiling-cold)
Haha holy shit…they thought THAT WAS AC?
This right here is the bare minimum as to why education is so important.
Just so you know, there are places where people live differently from you.
Would you expect the same level of knowledge about keeping a house warm at the equator? Because I’d argue you need to better your education if you do.

Then you can add humidity
Lots of places in the US don’t even get to a comfortable temperature at night. Right now I’m in Pennsylvania which is pretty far north and the lowest it’s going to get tonight is 80F with 80% humidity. It was 100F today with the same humidity. I actually got sick at work from it.
Damn, I didn’t expect it to be that bad outside of the southern states.
I’m currently getting ~30°C peak but about 15°C at night. We only have a few nights every year that reach 20°C. Austria.
Honestly, for me a reason why humans shouldn’t live in such places. For the Europeans here (that have not much clue of weird American units):
80 F = 26.667 C
100 F = 38 C
The temperature is not a big problem imo. The humidity though.

26? It’s pretty warm, but not too hot.

Then you certanly need ventilation or AC. I just have window open.
