När jag jobbade med Bonnier Online och bodde på Upplandsgatan i Stockholm, 1996 skaffade jag min första luftkonditioniering. #AC

Canadians just so goddamn tired of this bullshit

Me: Facts!

Les Canadiens•iennes sont câlissement tannées de cette tabarnaque de marde de trou de cul!

Moi: Faits!

Those projects are not getting as much attention as they should. Make a Daikin #AC smart, but in a #sovereign #nocloud way. https://codeberg.org/RevK/ESP32-Faikout

Some quick hits from my birthday yesterday in Animal Crossing. And, of course, Kiki can't help but call me baldy. Even on my birthday. Cold blooded.

Update:

I managed to measure the boundary layer temperature of my heavy load-bearing wall somewhat directly. I basically just used an additional air temp sensor, put it on the wall, and covered it with a blanket, leaving a small hole that was faced away from airstreams to account for moisture.

The data is not yet fully clear but as you can see via the graph, the green air temp stops raising when it approaches the yellow wall temp.

I am somewhat sure now that the temp of this wall is the most significant indicator of room temperature after I closed my windows and rolled down the blinds.

Until around 2:30 AM I pointed both of my fans to the windows, after that I let one of them cycle between the window and the wall.

I am still not sure if the fan pointed to the wall to get rid of the boundary layer is significant or if it would be better to just point the fan to the window.

There is almost no air movement I can measure or perceive at the wall if I point both fans to the window.

I think thermal inertia of the wall is quite impressive! It got blown on the entire night with 2C lower air and only lost temp very slowly. So it is either very bad at conducting heat or it is a good thermal battery.

After calculating the wall is about 3m³ of concrete which is round about 1.75 kWh/K. Which is lower than expected.

The convection exchange of this wall should be pretty low as it is obviously vertical... after looking into convection vs forced exchange (blowing onto the wall) calculation examples I guess that the temp exchange is about 3 to 5 times as high as with normal unsupported convection.

Thinks I want to test and see if they are relevant:

Messure different setups and distances from the window to the fans
Messure outside temps to optimize the "closing window" time. I think this should be the time when outside temps are maybe 0.5C under the wall temp as air kWh/K is super low and will be heated almost immediately to wall temp if closed. So even if indoor temp is cooler then outside temp it does not make sense to close the windows as long as outside temp is lower then wall temp.
Calculate how long and how often a given location on the wall must be blown upon to hit diminishing returns regarding the removal of the boundary layer to determine if it would be better if one fan just randomly blows at all walls, floor and sealing.
Set up better temp sensors for measuring wall temps.
Search for heat bridges
Blowing air at the upper portion of walls since I expected that the delta is bigger there.

Until now it is quite amazing that I can basically safe each day about 3 to 5 EURO on energy because I do not use a AC... which is also not very practical in my apartment.

There are times when this will not work like Sunday when we will have 25C at night and 40C at day.... but yah it is also questionable if a mobile renter friendly AC can even pull down the room temp at these outside temps especially if it is only a unit with 1 or 3 hoses instead of a split AC unit... which are a lot more expensive like 1k EUR and gigantic space wise... for about 3 days a year I cannot cool with Lüften.

Let's see how I think about this at Sunday

I can't even with the fucking #American POV and their shitty uninformed opinions about #AC in #Europe. The #heat #death count in Europe isn't anywhere close to as much higher as is widely claimed, because it's comparing Heat Stroke death to Excess Deaths during heatwaves over baseline. Second, AC is massively more expensive to install in Europe on average. My exterior walls are half a meter thick, and my widow is the size of a Manhattan studio apartment. That means the _only_ way to install AC would be to: A: Cut through medieval stonework B: Install custom windows. C: Use a terrible and inefficient movable AC. It is absolutely and completely preposterous. There isn't a "cultural antipathy" toward AC. AC is a terrible solution to the problems Europeans actually face,

Food Stores in Europe cannot keep their food cold. Their fridges dont work. No meat, no dairy for sale. Use powered cooling to save your life. The U.N. says heat has killed more than 1400 people in Europe so far that week. Tax Wealth DEEPLY and build the new Energy. End carbon or die in great numbers. https://www.gbnews.com/news/heatwave-supermarket-fridges-cant-cope-britons-unable-purchase-meat-dairy-products #climate #heat #ac #eu #cdnpoli

Technische Frage - kennt jemand eine Studie (keine Meinung bitte), in wie weit die warme Luft, die ein Klimagerät nach aussen abgibt, die Umgebungsluft aufheizt? Ich stelle mir vor, dass wenn man für den Strom (solar) und das Kältemittel (R-32) kontrolliert, nicht mehr viel Schaden übrigbleibt, aber ich wüsste es gern genauer. #klima #klimageraet #ac

Interesting, good article about the politics of air conditioning in Europe. (also, following @euronews@mas.to is kinda handy). TLDR, it's (unfortunately) become a political thing, with the right wing for AC and the left wing against AC. Euro News: To use air con or not? The facts behind the politicised battle to stay cool in Europe https://www.euronews.com/my-europe/2026/06/26/to-use-air-con-or-not-the-facts-behind-the-politicised-battle-to-stay-cool-in-europe #climateemergency #heatwave #AC

@ai6yr@m.ai6yr.org @euronews@mas.to Let's end AC when and where we can by replacing it wirh Heat Pumps. The fight against AC is a trap. The press has set by pushing "footprints" as the crisis. Climate isnt fought by not "stepping on cracks"! Its opposed by BUILDING SOLAR AND WIND, so no use of energy produces CO2 But finally Use powered cooling or die. 600 die on their beds, in the woods, in Canada. https://www.cbc.ca/news/canada/british-columbia/bc-heat-dome-sudden-deaths-revised-2021-1.6232758 #poweredCooling #ac #heatpump #france

An intetesting peculiarity of living in #SocialHousing is that we are explicitly banned from having window-based #AC in our units. While I live in #Alberta, my understanding is that this ban is found throughout social housing #leases in #Canada. Granted, the writing style and language choices strongly suggest such leases were drafted in the early 1970s at the latest, and back then I would have easily agreed that #AirConditioning would not be necessary. However, 50-some years on, the heat is routinely a bajillion (estimated 😛) degrees higher and #disabled folks and others in social housing are BANNED* from installing what is literally life-saving equipment under the 'new normal' of our #FireSeason summers. *TBC: portable AC units are not explicitly banned (not commercially-available yet when the leases were written??? 🤔) but these have limited range and are usually energy-inefficient compared to modern AC window units 6/x #health #safety #medical #medications #disability #poverty
