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.

A filter element for an air filter of a motor vehicle includes a frame part which surrounds a filter material of the filter element. The filter element is insertable into a receiving space which is provided by a housing of the air filter. The filter element has a holding element which is movable from an initial position into a functional position by inserting the filter element in the receiving space. In the functional position, a fastening element can be fixed to the holding element. The fastening element is configured for securing a cover element, which is used to close an insertion opening of the receiving space, to the housing.

In an air conditioning case, a blower sucks air flowing out from first and second upstream side ventilation paths from one side in an axial direction of a fan axis by rotation of a blower fan and allows the sucked air to flow to first and second downstream side ventilation paths. An upstream side guide member is provided on one side in the axial direction with respect to the blower fan and guides the air to the blower fan. Further, the upstream side guide member has a twisted shape and guides the air to the blower fan along the twisted shape.

A fastening module for connecting a filter system to an arched connecting surface with openings for a fluid has a connecting housing connectable in fluid communication to the filter system. Rigid individual channel pieces are arranged in the connecting housing and channels extend in the channel pieces. The channels correspond with the openings in the arched connecting surface. The channel pieces have connecting flanges to be connected to the openings in the arched connecting surface. The channel pieces are connected by flexible connecting regions with each other; with the connecting housing; or with each other and with the connecting housing. The fastening module is connected in fluid communication to the inlet region or outlet region of the filter system. A filter module for the filter system has substantially free intake across its cross section and enables an intake manifold-type distribution of a volume flow passing through the filter element.

The motor support (16) for a motor-fan unit of a ventilation installation for a vehicle comprises: two coaxial rings (20; 22), including an inner ring (20) capable of receiving one or more elements of the motor and an outer ring (22) capable of fixing fastened to a housing forming a structural element, a decoupling element (24) between the two coaxial rings (20; 22); and a means (44) for limiting the relative movement of one of the two rings (20:22) relative to the other, in a plane normal to the common axis (A) of the two rings (20; 22) comprising at least one radial abutment (44) fastened to one of the two rings (20; 22), with a radial clearance between the radial abutment (44) and the other of the two rings (20; 22).

An air conditioning system for a vehicle, having an evaporator configured for a heat exchange between a coolant and air, a fan configured to generate an air flow passing through the evaporator and intended to be fed into a vehicle passenger compartment, at least one pressure sensor configured to measure the pressure of the coolant, and a control unit to adjust the rotation speed of the fan, configured to automatically decrease the rotation speed of the fan when the detected pressure of the coolant rises above a pressure threshold, so as to reduce the air flow on the evaporator and thus reduce the pressure of the coolant is provided.

A thermal management module for a thermal management system is disclosed. The thermal management module includes a first heat exchanger for flowing through by a refrigerant and by a working medium fluidically separately with respect to the refrigerant. A second heat exchanger is provided including at least a first fluid path and at least a second fluid path, separate from the first fluid path, respectively for flowing through by the refrigerant. A connecting arrangement is arranged between the first heat exchanger and the second heat exchanger. The connecting arrangement connects the first heat exchanger and the second heat exchanger to one another mechanically and fluidically, so that the refrigerant can flow between the first heat exchanger and the second heat exchanger.

A parking cooler which is capable of battery powered operation during engine off operation. The parking cooler or air conditioning system may vary in cooling capacities to maximize cooling or maximize battery life. The parking cooler includes one or more condensers and a housing to accommodate such variation of cooling capacity.

The present invention relates to an air conditioner for a vehicle, which includes an air-conditioning case (200), and at least one door (100) mounted to be opened and closed at a predetermined position, wherein the door (100) is formed integrally with an arm pivot (140), and the arm pivot (140) includes a pin part, and ribs formed integrally with both sides of the pin part to reinforce rigidity of the pin part and offset noise. The air conditioner further includes distortion preventing parts formed on a rotary shaft to be dented and to be crossed to each other, thereby reducing a transformation rate of the door and securing accuracy of the pin part.

Various disclosed embodiments include illustrative heating, ventilation, and air conditioning (HVAC) devices, HVAC systems, vehicles, and methods. An illustrative HVAC system includes a case configured to at least partially recirculate air within the case, a blower disposed in the case and configured to cause air to flow, a first heat exchanger disposed in the case and configured to heat the air, and a second heat exchanger disposed in the case and configured to exchange heat with the air.
