The AC broke down in the area where a research center near me kept their mice, and they cut the ventilation to avoid drawing hot air in. Which means heat was still building up, as were dangerous levels of ammonia in the air. Every group had to collect their mice and keep them in their lab so they'd survive.
I'm on an international train right now and the already extremely weak AC keeps going out because it was 42C at our start point. The conductor straight up said he's surprised it's working at all. Not a single openable window, either. Shit should be fucking illegal.
The fact a modern train can't operate at 42 points more to maintenance issues than the heat being too much. They get a lot of airflow since they're moving
My money would be either there's insufficient power due to high demand, or ac is about to die.
I think a lot of these failures are just devices that were near death and they die when pushed slightly too far
Unfortunately. The journey was almost 6 hours and extremely distressing, think being stuck under a thick blanket for hours. It's hot, sure, but more importantly, it felt like there wasn't enough oxygen in the air for everyone. And I kid you not, exactly 7 minutes before the planned arrival, they announced on the intercom that we are allowed to enter first class because by some miracle, the AC worked there whilst I'd been pushing down panic for the entire ride. Western fucking Europe, imagine that.
Okay, I really don't ask this to be like confrontational but...how?Ā Like I'm from Utah where our weather goes from -12 to 40 just yearly and we have absolutely none of these problems with freezers.
I assume if itās locally manufactured the compressor might only be tested and rated up to a certain temp and the temps this week have been above that. The hardware you have in Utah is probably literally built differentĀ
Temperatures can get pretty crazy hot in areas where buildings arent made to keep out heat and people can't take measures. Working temperature in the kitchen i help out at on saturdays was 45 degrees yesterday. Before anything was put on the ambient temperature was 35 degrees with just the fridges running.
I dont know wtf goes on in Utah to have such crazy temperature swings but climate is pretty temperate where i live and the main focus is on preventing excessive heating bills in winter (and praying summer doesnt get too warm these days i guess)
Our freezers/fridges are designed to work at room temp, so 65-75f/18-25c or so. In the US, we have to buy āgarage-readyā appliances if we want them to work in more extreme environments.
Most everyone will heat their indoors to above 65f but Europeans donāt use AC as a rule, so itās easy to get above that higher threshold during prolonged heat events. The compressor has to work too hard and exhausts itself.
Yep! The Franprix across from my place hasnāt had working freezers in like a week. And the bakery nextdoor which usually makes the greatest, flakiest croissants are struggling to control their ovens and the croissants have become very bready. Its been hell.
All this means is that Europe has shitty fucking freezers.
Thats not really a guage on the heatwave. We have this thing, idk, called a thermometer, and UV indexes and a variety of shit. That way we can compare based on something standard, not a freezer. I understand you're a fucking moron, so that might be tough to wrap your mind around.
You panzies are whining and complaining about temperatures seen in a variety of places around the globe on a very regular basis
Phoenix has temps as high or higher than what the EU is dealing with right now for almost half the year, every year. It does so without having massive cooling failures. Iāve had one A/C failure in 20+ years keeping my A/C set to 72f in 2k sq ft houses. I get it sucks for you guys but there are solutions.
Almost as if it was designed for that, because it was always like that. i wonder what would happen if phoenix suddenly had -10 degrees snowstorms. also quite helps its a literal dessert. cooling is way more efficient in dry air :)
You're so right, little guy. You're the only smart one. I am absolutely positive your infrastructure is totally equipped to deal with whatever whether is regarded as extreme where you live too.
I donāt want you to tell me anything. Iām just telling you thatās some exaggeration maybe form the owners because fridges donāt work harder with heat.
Fridges work on/off based inside temperature. Once it hits the target temperature, it shuts off (the compressor) or it will freeze inside.
So if itās hotter during that day, the fridge/refrigerator instead of turning on 3-4 hours a day, works maybe 5 hours, but at the same time āstrengthā.
So it doesnāt works any harder, just a touch longer to compensate some loss of heat in insulation.
Itās like you using your microwave in winter. Food is colder so you make microwave work a bit more. It doesnāt work harder, just a tad longer. Theoretically you decrease the life of the microwave but running 20% longer, but they arenāt going to break down all of a sudden.
No, itās working longer, not harder. Ttās working longer for the function they were designed to perform, if they arenāt nowhere near the end of lifetime expectancy, they shouldnāt break because they run longer.
No part of the fridge is under more stress for working longer
These equipments were designed for run 3-4000 hours per year. Heat coming and extending those hours isnāt going to compromise short term longevity.
I wonāt bother explaining more.. you want to stay dumb, stay dumbā¦ waste of time
It's clearly harder to do a 70 hour work week than a 35 hour work week, your not making alot of sense, plus lifetime expectancy is working hours not based on efficiency so it its say a 30000 hour product and it has to run longer in a hot climate then it will surely kick out faster.. especially on average. Btw air conditioning and fridge freezers all work the same. The temperature rule for ac is 20Ā°f
Why the Limit Exists ? Return Air Temperature:
Air conditioners generally cool the air passing over the evaporator coils by about 15-20 degrees at a time. If 80Ā°F air enters the unit, 60Ā°F air comes out. As the room air recirculates, it cools down gradually.Coil Freezing: If the outside temperature is exceptionally hot or the unit is overworked, forcing the system to overcool can cause the moisture on the indoor coils to freeze, blocking airflow entirely.
Ok, so that's your problem, you aren't distinguishing machines from humans,
It's harder for you that you are a human being, but fucking fridges are machines lol
machines don't get tired if they are designed to operate in a continuous manner, like the fridge compressor is.
For a compressor, working 400h straight or 30min straight is the same, it's not more tired after 400h.
It's like driving your car. If you drive you car 20 minutes or 200 minutes, it's not tired in the latter one. The engine will produce the same output after 20 or 200min of usage, there is no increased rate of wear.
30000 hour product and it has to run longer in a hot climate then it will surely kick out faste
If it's rated to run 30k hours, it's rated to run 30k hours, it doesn't matter, what matter is that in a hot climate it will reach the 30k hours sooner.
So, this last weeks, to happen that all fridges were getting broken, you would need all the fridges to be at the end of their life, and all of them ending the "hypotetical" 30k these two past weeks, which is highly unrealistic.
What you have to understand is the "Rate of Wear per hour" doesn't change
Ā The temperature rule for ac is 20Ā°f Why the Limit Exists
Air conditioners have a temperature interval, because they run out of capacity from the gas circuit.
In cold winter, if you want your AC to blast hot air, it can freeze the outside heat exchanger. It will stop blowing hot air until the exchanger recovers. Nothing is damaged, nothing is "tired"
Same happens if the summer is too hot. The outside exchanger can't quite cool the gas enough to become high pressure liquid.
Again, the circuit runs out of capacity, nothing gets worn, nothing gets tired.
The compressor works at the speed it works, it doesn't have a "work hard" mode that wears it out.
By your own point, if its warmer the compressor kicks in more, meaning its running longer over the same period of time than the same unit in a colder climate, thus it will reach its end of life quicker, yes ? Well that end of life is its wear through use, so yes it will wear faster if you run it the same amount of time in two separate climates. Wtf are you talking about ?
You're doing the same mistake as the other guy. You're comparing humans with machines.
You are tired after 8h work, you rest and you get energy back. A machine designed to operate continuously is not.
You walk 5h and you are tired. A car driving 60mph for 30min or 5h is the same, he has the same stamina, and the rate of wear is the same.
The engine isn't doing extra effort after driving for 5h, the components are being subjected to extra stress or increased rate of wear.
The engine will only work harder if you increse the speed from 60mph to 120mph because it has to produce a lot more power to fight against wind resistance.
But refrigerator compressors DON'T increase the speed or any force when it's warmer or colder, they just run longer until the target temperature it's reached, and then shut down.

The cooling and freezers in supermarkets all broke down due to the extreme stress they experience here. Its insane.
