Even after searching it up I still don’t understand how it cools down air.
And what exactly does Freon do?

If you squeeze air into a tiny little space, a tiny tank, the air heats up. You’re probably thinking that’s the opposite of what you want to do. But let’s take that tank of very hot gas outside. The tank of air is hotter than the air outside, so the tank cools down to be the same temperature as the outside air.
Now we bring the tank back inside. It’s still warmer than we want it. In fact it is still as warm as the outside air. But it’s cooler than it was when we took it outside.
Now we do the opposite of squeezing it. We let it expand. This causes the air in the tank to cool down. The air in the tank is now cooler than the air in the house.
The air in the house causes the tank to warm up some. In doing so, heat energy is transferred from the house to the tank, which causes the house to cool down.
Now we squeeze the tank again and the process starts over.
