How car airconditioning works?

Answer 1

Car airconditioning works similarly to the air con in your house. As freon is compressed it cools, in the lines of a air conditioner is freon. The compressor pressurises the freon in the lines and those lines run through a condensor box that has air flowing through it. Those lines cool, and as such the air blowing by them cools and comes out the car vents. This is simplistic but accurate.
