Problems solved by technology

Such scent cartridges interfere with the air guidance, generate undesired air turbulence and may likewise lead to increased flow noise
[0006] In general, the aromatization of the conditioned air is carried out by means of additional air treatment units, which requires additional space in the air conditioning system and entails additional costs for installation

Embodiment Construction

[0028] figure 1 An air conditioning system 1 for an interior, for example of a motor vehicle or the like, is shown schematically. The air conditioning system 1 comprises ventilation means 2 to draw in fresh air from the surrounding environment and provide an air flow which then passes through a heat exchanger 3 to cool or heat the conditioned air.

[0029] Downstream of the heat exchanger 3 , an air treatment device 4 is arranged in the air flow before it enters the inner chamber 5 . In particular, the air treatment device 4 is arranged directly on the air outlet 6 or as close as possible in the interior 5 to the air outlet 6 and can be arranged exchangeably in the air flow.

[0030] figure 2 a and 2b show various views of an exemplary air treatment device 4 . exist figure 2 In a is shown a sectional view along the longitudinal direction L, which corresponds to the flow direction of the conditioned air. figure 2 b shows the corresponding cross-sectional view. figure ...

Abstract

The present invention relates to an air preparation device (4) of use in an air flow path of an air-conditioning system (1) in a mobile device. The air preparation device includes treatment elements (41, 51) having one or more passages (42, 53 and 65) extending in part or completely in a flow direction. The passages (42, 53 and 65) include fragrancing faces (43) that extend in the flow direction and are designed to release one or more fragrant substances into an airflow that is flowing through.

Description

technical field [0001] The invention relates to an air treatment device for being arranged in an air flow for air-conditioning an interior, in particular a mobile device, such as the interior of a motor vehicle. Background technique [0002] An air handling unit may be used to provide fragrance to conditioned air prior to introducing it into the interior. Frequently, air treatment devices of this type are formed with a non-woven fabric impregnated with fragrance substances arranged in the flow path. The ventilation device conveys an air flow through the fleece in the direction of the inner chamber. [0003] The volume of nonwovens impregnated with fragrance substances is very limited, so that the fragrance effect lasts only for a short time. It is also not possible to adjust the intensity of flavoring with this system. As a result, the flavoring effect decreases significantly over time. [0004] Furthermore, such air treatment devices create a flow resistance, due to whi...
