How does air conditioning work?

I need a brief summary of how it works. Like just a few sentences.

    Refrigerated air conditioning works on the principle that when you compress a gas (even air) you trap the temperature of that gas and the temperature rises higher in proportion to the pressure being exerted on it. Then when you run the compressed gas through a cooler (condenser) the heat is lost. Then you pump the cool-down gas, which is now a liquid, back to the evaporator and when the pressure on the cooled down liquid is released, it diverts back into a gas but much colder. And the difference in lost heat is what you feel. If the inside air temperature is say 80 degrees and you run it through an air conditioning system and loose 40 degrees in the coolant to the outdoors, then the coolant will come back inside and be distributed via a blower at 40 degrees.

    The basic concept is that as a gas moves from an area of high pressure to an area of low pressure, it gets colder (high pressure = high temp, and low pressure = low temp). Your AC has freon at high pressure in a can, it uses electricity to force this freon through a tiny hole into a larger area, thereby dropping the pressure and temperature rapidly. Fans then blow this cold air out into your house.

    Freon is becomming less common as a refridgerant, since it could be harmful to the environment.

    Its a little more complicated, but that is the basics of it.

    No, refrigerant doesn't get colder in the evaporator but instead it boils into a vapor under this lower pressure side of the system and it's a law of physics that a boiling liquid is changing state to a gas and that causes it to ABSORB heat, so it just feels cold to you. Rubbing alcohol does the same thing on your skin better than water because it evaporates more quickly ( has a lower boiling point)

    Air Conditioners work by removing warm and hot air from a room. Most people think that the air conditioner is pumping cold air into the room, which it does, but that is misleading.

    In a summarized sentence, air conditioners take advantage of a chemical reaction in a compound we call refrigerant. When this chemical changes from a liquid state into gas state it cools down. You can see a more detail description and example on how this reaction works in this source

    Air conditioners use refrigerant to absorb heat out of the air as it passes through the indoor unit. The outdoor unit expels the heat into the outside air as it passes the unit that is outside
