ML 55 AMG (163.174) V8-5.5L (113.981) (2001)
Operating condition: HEATING
Function
In the heating operating status, the fresh air (A) is drawn in by the blower (5) into the evaporator housing and routed through the dust filter (3). The air
purified by the dust filter (3) is then routed through the evaporator (2) and dried there. The fresh air (B), which has been dried, cooled and cleaned, is
subsequently routed through the heat exchanger (1). This air conduction is controlled via the setting of the blending air flaps (6).
The fresh air (B), which has been dried, cooled and cleaned, is heated up again in the heat exchanger (1). The warm air (C) is conducted via the air
outlets (E, F, M and S) into the vehicle interior. The recirculated air flap (4) is closed.
Operating condition: cooling
Function
In the cooling operating status, the fresh air (A) is drawn in by the blower (5) into the evaporator housing and routed through the dust filter (3). The air
purified by the dust filter (3) is then routed through the evaporator (2) and dried there. The fresh air (B), which has been dried, cooled and cleaned, is
subsequently routed around the heat exchanger (1). This air conduction is controlled via the setting of the blending air flaps (6).
