The air conditioning unit in your vehicle operates similarly to a refrigerator. Your vehicle's air conditioning unit is designed to move heat from the inside of your car to outside of it. The refrigerant carries heat. In modern cars, refrigerant is a substance called R-134a. Older cars' refrigerant is called r-12 freon, which is more expensive and difficult to find than R-134a. The compressor circulates and compresses refrigerant within the vehicle's cooling system. Your vehicle's condenser changes the refrigerant from gas to liquid and expels heat from the car.
