To beat the summer heat, we turn to air conditioning. But that sweet, cool relief isn’t magic: it’s the science of heat transfer and the chemistry of refrigerants.

I didn't even understand a single thing. The female talking seems to focus more on making jokes then explaining the damn thing.
Love your voice, it made it not boring, and quite fun 😅
Good content, a lot more involved than what I thought.
This is the best explanation on YouTube on how the system works
Alright you know what. Ive watched this video like 3 times and watched 3 other videos explaining an A/C and in general I do understand the fundamentals of how an A/C works but I still don't fully understand it like how the hell do compressors work and how does the A/C turb my 39°C room to 18°C in a matter of seconds. So, I'm getting a book about A/Cs
Wait does this mean that those air hot thing (reverse air conditioner) that really cold countries use is just an air conditioner but the air conditioner is put outside and the hot fan thingy is put inside.
after february summer need AC
ty i was wondering how this worked
Does the condenser condense air absorbed from outside or from the inside?
Physics Has Left The Chat!!
"Outside, where it's hot and miserable anyway. Who cares." WOW!
Whoever makes these scrips should be fired
funny narrator
welp, I guess my roommates are moving out 2:51
So i wont get fresh air from air conditioner…………….🤨
Great Explanation
1:05
"So, who cares?!" Future generations are gonna have to put up with the heat that we're dumping into the environment. Literal definition of global warming.
thank you i need to cool down my base in oxygen not included
Video should explain a bit more on the condenser coil instead of using 1/2 the video on choosing type of gas. I am still a bit confused on how the gas turns into liquid state again…
There are a lot of side comments from her. It makes it harder to understand
Great video
Sweet way of explaining things
So turn my ac backwards if I want heat and all the cool air out lol
how in the world is a third option of propane or butane even remotely a possibility? Basic qualifications are non-flammable. did you research this before you posted? lol
Below link helped me a lot to understand..
easier than this video.

This may sound like a very stupid question for an expert, but what are/is the benefit(s) of having a refrigerant with a low boiling point instead of a higher one? Does this keep the cycle going somehow in the system? Also, wouldn't a higher boiling point absorb more heat?
So….. The cool air get in and the hot air get out wow
