Air distribution arrangement with inflatable pipes for an air conditioning unit
An air distribution arrangement for an air conditioning unit is provided. The air distribution arrangement includes a main body coupled to a housing of the air conditioning unit, and provided with a distribution chamber fluidically connected to at least one air transport conduit formed within the housing of the air conditioning unit, and a plurality of distribution pipes connected to the main body and configured to be connected to respective air outlets for distributing air within a cabin of a vehicle. Each of the distribution pipes is flexible and at least partially inflatable due to an air flow within it.
1. An air distribution arrangement for an air conditioning unit, the air distribution arrangement comprising:
a main body coupled to a housing of the air conditioning unit, and provided with a distribution chamber fluidically connected to at least one air transport conduit formed within the housing of the air conditioning unit,
a plurality of distribution pipes connected to the main body and configured to be connected with respective air outlets for distributing air within a cabin of a vehicle, wherein each distribution pipe is flexible and at least in part inflatable due to an air flow within it, and
a plurality of throttling members disposed such that they successively alternate with the distribution pipes, the throttling members being controllable to adjust air passage cross-section of the distribution pipes, to selectively close or open the distribution pipes,
wherein each distribution pipe is interposed between a respective pair of throttling members, at least one of which is movable to selectively move the throttling members towards each other or move the throttling members away from each other, and
wherein a single throttling member of the plurality of throttling members is configured to adjust air passage cross-section of two adjacent distribution pipes.
2. The air distribution arrangement of claim 1 , wherein each throttling member of the plurality of throttling members is configured to engage a wall of a respective distribution pipe.
3. The air distribution arrangement of claim 2 , wherein each throttling member of the plurality of throttling members is attached to the respective distribution pipe.
4. The air distribution arrangement of claim 1 , wherein the main body is of rigid material and carries a frame on which at least one throttling member of the plurality of throttling members is mounted.
5. The air distribution arrangement of claim 4 , wherein the at least one throttling member is slidably arranged along the frame.
6. The air distribution arrangement of claim 4 , further comprising an array of heating elements carried by the main body and controllable independently from each other, the array of heating elements being placed in front of an array of inlets of the distribution pipes arranged on the main body.
7. An air conditioning unit comprising the air distribution arrangement of claim 1 .
