GF83.40-P-2105-02GI Automatic Air Conditioning Box Function

GF83.40-P-2105-02GI Automatic Air Conditioning Box Function
- with CODE (580a) Automatic air conditioning







Operating condition: HEATING

Function
When in heating mode, the blower motor (5) draws in fresh air (A) to the automatic air conditioning box and routes it through the multipurpose filter (3). The air cleaned by the multipurpose filter (3) is then routed to the evaporator core (2) and dried there. The dried, cooled and filtered air (B) is then routed on through the heat exchanger (1). This air conduction is controlled via the setting of the blending air flaps (6).

The dried, cooled and filtered air (B) is then heated up again in the hot heat exchanger (1). The warm air (C) is routed via the air outlets (E, F, FR, M and S) into the vehicle interior. The fresh air/recirculated air flap (4) is closed.







Operating condition: cooling.

Function
When in cooling mode, the blower motor (5) draws in fresh air (A) to the automatic air conditioning box and routes it through the multipurpose filter (3). The air cleaned by the multipurpose filter (3) is then routed to the evaporator core (2) and dried there. The dried, cooled and filtered air (B) is then routed around the heat exchanger (1). This air conduction is controlled via the setting of the blending air flaps (6).


The dried, cooled and filtered air (B) is routed directly into the passenger compartment via the air outlets (E, F, FR, M and S). The fresh air/recirculated air flap (4) is closed.







Operating condition: Blend air (warm/cold)

Function
When in blending mode, the blower motor (5) draws in fresh air (A) to the automatic air conditioning box and routes it through the multipurpose filter (3). The air cleaned by the multipurpose filter (3) is then routed to the evaporator core (2) and dried there. Some of the dried, cooled and filtered air (B) is routed onwards by the heat exchanger (1) and some is routed around the heat exchanger (1). This air conduction is controlled via the center setting of the blending air flaps (6).

The dried, cooled and filtered air (B) which was routed through the heat exchanger (1) is then heated up again. After passing through the blending air flaps (6) this heated air (C) is mixed up to form blend air (D) with the dried, cooled and filtered air, which was routed around the heat exchanger (1). This blend air (D) is then routed via the air outlets (E, F, FR, M and S) into the passenger compartment. The fresh air/recirculated air flap (4) is closed.







Operating condition: Cooling down "recirculation air"

Function
In cooling mode with recirculated air, the blower motor (5) draws in recirculated air (A) from the passenger compartment via the opened fresh air/recirculated air flap (4) into the automatic air-conditioning box and routes it through the multipurpose filter (3). The air cleaned by the multipurpose filter (3) is then routed to the evaporator core (2) and dried there. The dried, cooled and filtered air (B) is then routed around the heat exchanger (1). This air conduction is controlled via the setting of the blend air flap (6).

The dried, cooled and filtered air (B) is routed directly into the passenger compartment via the air outlets (E, F, FR, M and S). The supply of fresh-air is cut off by the fresh air/recirculation flap (4).
