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

An air conditioner is a kind of heat pump, which makes heat flow from one place to another just like a water pump. The place you pump heat away from gets colder and the place you pump it to gets hotter.
The most common kind of heat pump uses a refrigerant in a vapor cycle, meaning it pumps a fluid around in a loop between the side where you want to dump heat and the side you want to pull out heat or make cold. To make the fluid flow in the loop you need a fluid pump, so this heat pump has a fluid pump as part of it.
Let’s go around the loop starting at the pump. The pump uses electricity to spin a motor to push the fluid forward through the loop. So at the outlet of the pump the fluid is at higher pressure. The fluid is chosen such that when you increase its pressure with a pump it will also have higher temperature. Some fluids such as water would not increase in temperature much, but a refrigerant like freon does.
So now you have hot high pressure fluid leaving the pump. The pipes it flows through will also be hot, and so if you blow a bunch of air across those pipes some of the gets will go into the air, and you can blow that hot air outside or something. That is heat being pushed out of your heat pump.
Now you have high pressure fluid that is not so hot, maybe medium temperature. Then you put a blockage in the pipe with a little hole in it to restrict the fluid flow and then let the pipe get bigger, which will lower the pressure and temperature of the fluid. Now you blow air over these low pressure low temperature pipes, and the heat will go out of the air into the fluid and make the air colder, and then you blow that out a different place from your gets pump, now that’s the cold side taking in heat.
