Problems solved by technology

Another disadvantage is the impossibility of the sliding element to independently activate the first and second partial channels
Furthermore, it is disadvantageous that the known air-conditioning systems do not have a third partial channel associated with the footwell of the passenger cabin
The known air-conditioning systems therefore fulfill the requirements for zone separation and temperature stratification only under certain conditions

Embodiment Construction

[0024] exist figure 1 In , all flaps used to control openings are depicted in two positions, a closed position depicted in dashed lines (in which the flaps close their respective openings), and an open position depicted in solid lines (in which the flaps close respective openings open).

[0025] Such as figure 1 As shown, an air conditioning system 1 for air conditioning a passenger cabin with a front area and a rear area has a housing 2 in which an evaporator 3 for cooling the air flow and an evaporator 3 for heating the air flow are arranged. Two heating devices 4. It is also conceivable for the air conditioning system 1 to have only one heating device 4 or more than two heating devices 4 . In practice, the upstream front or first heating means 4 is a conventional heat exchanger 36 through which a heating medium can flow. Usually such a heat exchanger 36 is connected to a cooling circuit in which a cooling fluid circulates. First of all, this is the cooling circuit of t...

Abstract

The invention relates to an air-conditioning system (1) for air-conditioning a passenger cabin having a front region and a rear region, the invention relates to a refrigerator comprising a housing (2)in which an evaporator (3) and at least one heating device (4) are arranged, wherein the housing (2) has an air inlet (5), a front outlet (6), a rear outlet (7) and a foot space outlet (8), a cold air space (9), a hot air space (10) are present in the housing (2), and a front mixing space (11), a rear mixing space (13) and a stratified mixing space (12) are present downstream of the hot air space(10) and the cold air space (9). The hot air space (10) is separated from the front mixing space (11) and the stratified mixing space (12) by a front partition wall (14) and from the rear mixing space (13) by a rear partition wall (15). Improved comfort is obtained when the front flap (16), the layered flap (18) and the rear flap (20) are arranged downstream of the at least one heating device (4).

Description

technical field [0001] The invention relates to an air-conditioning system for air-conditioning a passenger cabin having a front area and a rear area. Background technique [0002] Air conditioning systems are now standard equipment in most motor vehicles and always include an evaporator and at least one heating device, for example in the form of a heat exchanger. The total air flow from the air flow cooled by the evaporator and the air flow heated by the heating device can be combined differently by means of the control element, and the total air flow is then supplied to different channels, which lead to different areas of the passenger compartment . In particular, the interaction of control elements and their arrangement is becoming more and more important in air conditioning systems due to the increasing requirements for zone separation and temperature stratification in high-quality zones. [0003] An air conditioning system for a motor vehicle is known from DE 10 2004 ...
