Every school deserves a teacher like Zack

I love how simple you explain it instead of trying to explain the atoms and physics of why it can do it

Finally someone who made AC easy to understand without mentioning all those alien words

So I finally got my answer. At this point, the animations are getting less scarier everyday.

looks like zack has been putting that guy and his hand through a lot of pain and torture

It’s actually pretty cool how they work. (No pun intended lol)

“WHY IS IT SO HOT OUTSIDE!?”
“Sorry bro needed my ac”

No wonder it was even hotter in the summer when we used to live in the apartments

This whole time I thought it was bringing in air from outside 😭

"its way too cold outside!"
"turn on the AC"

The AC unit is just a magical machine that sucks up all our hot air and spits out coolness

What's crazy is that I was so hot once that the hot air felt like a cool fan for me.

That van really was a mobile microwave...

Me: That hand is awfully realistic lol

It's very accurate but the most important part is left out. It's that the phase change of the refrigerant is what traps or releases heat, and its the reason AC unit can pull heat from very cold air.

I finally understand, I thought it was more complex!

I wouldn’t call it an “absorbed heat”. It is heat produced by cooling the coil. Heat that come from room just gets cooled down and that’s how it’s gone

Engineering student here! It's actually pretty simple:

1) Compress the refrigerant, making it a hot gas.
2) Let it cool until it's the same temp as before (which turns it into a liquid). This heat goes outdoors.
3) Let it expand, cooling it down below the room's temp; this is where the coldness comes from.
4) The room's heat enters the cold refrigerant, cooling the room. The refrigerant also turns into a gas.
5) Repeat

The phase changes between liquid and gas make the refrigerant extra effective at cooling, which is why refrigerants have low boiling points.

Fun fact: without AC, semiconductor factories wouldn't exist, so neither would phones or computers
