Air-conditioning Basics
An AC system is basically a refrigerator without the insulated box. It uses the evaporation of a refrigerant, like Freon, to provide cooling. The mechanics of the Freon evaporation cycle are the same in a refrigerator as in an air conditioner,the term Freon is generically "used for any of various nonflammable fluorocarbons used as refrigerants and as propellants for aerosols."
This is how the evaporation cycle in an AC system works!
The compressor compresses cool Freon gas, causing it to become hot, high-pressure Freon gas.
This hot gas runs through a set of coils so it can dissipate its heat, and it condenses into a liquid.
The Freon liquid runs through an expansion valve, and in the process it evaporates to become cold, low-pressure Freon gas.
This cold gas runs through a set of coils that allow the gas to absorb heat and cool down the air inside the car.
Mixed in with the Freon is a small amount of lightweight oil. This oil lubricates the compressor.
Air conditioners help clean your vehicles air as well. All AC units have filters that catch dust, pollen, mold spores and other allergens as well as smoke and everyday dirt found in the air. Most air conditioners also function as dehumidifiers. They take excess water from the air and use it to help cool the unit before getting rid of the water through a hose to the outside.Some systems use the condensed moisture to improve efficiency by routing the cooled water back into the system to be reused.
So this is the general concept involved in air conditioning.
