6.2. Conditioner
The conditioner in salon of the car establishes temperature below air temperature. If the conditioner is switched on, in salon humidity of air also decreases. In the presence of the conditioner the dust filter also is always established. The cooling device is integrated into standard system of heating and ventilation, and it is possible to cool salon of the car also. The conditioner works by a refrigerator principle: the compressor put in action from the engine through maple belt, condenses a vaporous, non-polluting coolant (R 134а). Thus the coolant heats up and goes to the condenser. There it is cooled and diluted. The Isparitelny valve injects the cooled liquid into the evaporator which is similar on the design to the refrigerator. The coolant evaporates in it. As a result of evaporation process flowing round outside of a lattice or a pipe air loses heat. Thus air is cooled and humidity as a result of formation of kondensatsionny moisture raises. At the rotating engine and the switched-on fan in salon of the car the cooled air through various entrance openings can arrive. Mercedes-Benz of the S-class is available on sale with two options of cooling: conditioner and automatic climate. Differences of these two options consists in management and service. While at the established conditioner adjustment of temperature is carried out separately for the left and right part of salon, at automatic climate the temperature is regulated at the same time for the right and left part of salon of the car. Advantage of automatic climate in front of the conditioner is that there is in addition "AUTO" switching. If it is put in action, there is completely automatic control of amount of air and its distribution in salon. If "AUTO" is disconnected, the driver himself can define amount of air and its distribution, as at usual heating and ventilation, but, naturally, also for both parts of salon of the car together.
