WARNING: This page does not describe the selected car, but rather 42 other vehicles, including the 1999 Mercedes-Benz S600, 1999 Mercedes-Benz S500, 1999 Mercedes-Benz S420, 1999 Mercedes-Benz S320, and 1999 Mercedes-Benz CL600. However, it is still accessible from the selected car via links, so may be relevant.
The liquid refrigerant is injected into the rear evaporator under high pressure. The heat required for evaporation is taken from the air flowing past the evaporator which is cooled down. The fins and louvers provide the evaporator with a large surface to ensure quick exchange of the heat. The moisture in the air which condenses out as the air cools is drained to the outside by water condensate drain hoses.
In addition solid particles in the air are bound by the water as it condenses thereby purifying the air.
