An air conditioner for a vehicle includes: a casing to accommodate a cooler and a heater; a front temp door disposed in the casing to control a temperature of air supplied to a front seat zone; a rear temp door disposed under the front temp door to control a temperature of air supplied to a rear seat zone; and a rear vent disposed at a lower portion of the casing to discharge air to the rear seat zone. The air conditioner can secure the flow rate of the air that is supplied to the rear seat zone of the interior of a vehicle by improving the route for flow of the air that is supplied to the rear seat zone.

A heating, ventilation and/or air-conditioning device for a motor vehicle, with a housing which includes a first duct for a first air stream, a second duct for a second air stream, a partition placed inside the housing so as to separate the ducts, a first heat exchanger arranged in the ducts, said heat exchanger being common to the two ducts, a second heat exchanger which is located downstream of the first heat exchanger and is arranged within a single duct, a first flap located downstream of the second heat exchanger, an air stream guide wall which is arranged inside the first duct, downstream of the first heat exchanger, and directs the first air stream in the direction of the first flap. The housing includes a space between the air stream guide wall and the first flap so that the first flap will not abut against the air stream guide wall.

An air distribution assembly for a recreational vehicle may include a frame mounted within an opening of the recreational vehicle and a baffle positioned therein to sealing divide an air handling chamber into an air supply side and an air return side. The baffle may include mounting flanges for rigidly connecting the baffle to the inside surface of the frame.

The invention relates to a ventilation device for a vehicle ventilation, heating and/or air-conditioning system, including at least one housing that includes at least one wall defining an inner volume in which at least one radial propeller capable of being rotated and at least one guide member are received, the radial propeller and the guide member being configured to generate an air flow having a general direction parallel to an axis of rotation of the radial propeller between an air inlet of the radial propeller and an air outlet formed in the wall of the housing of the ventilation device, at least a part of the wall of the housing being configured to straighten the air flow at the outlet of the radial propeller. The guide member is configured to direct the air flow towards the axis of rotation of the radial propeller.

Disclosed is a heating module (12) for a heating system (10) of a habitable vehicle, the module comprising: a module housing (36) having an air inlet opening (56) and an air outlet opening (58); an air conduction element (76) which is accommodated in the module housing (36), has multiple conduction sections (92, 94, 96), and is connected to the air inlet opening (56) and the air outlet opening (58); and at least one heating element (110, 112; 210, 212), said heating element (110, 112; 210, 212) being designed to heat air flowing from the air inlet opening (56) to the air outlet opening (58).

An inlet subassembly for a heating, ventilation, and air conditioning (HVAC) system. The inlet subassembly includes a divider defining a first airflow path and a second airflow path on opposite sides of the divider. The first airflow path extends from a first side of the recirculation air inlet and a first side of the fresh air inlet. The second airflow path extends from a second side of the recirculation air inlet and a second side of the fresh air inlet. A first inlet door is movable to control airflow into the first airflow path from the first side of the recirculation air inlet or the first side of the fresh air inlet. A second inlet door is movable to control airflow into the second airflow path from the second side of the recirculation air inlet or the second side of the fresh air inlet.

A heating, ventilation and/or air conditioning unit (10) for a car is specified, having a first air guide (22) for guiding a first, cold air stream and having a second air guide (24) for guiding a second, warm air stream which is separate from the first air stream, wherein a heating device (26) for warming the second air stream is arranged in the second air guide (24). The heating, ventilation and/or air conditioning unit (10) furthermore has a first mixing chamber (28) and a second mixing chamber (30), wherein the first mixing chamber (28) and the second air guide (24) each have at least one inlet opening (32, 34) to the second mixing chamber (30). In the second air guide (24), there is arranged a flap (44) which is movable between a closed position, in which a flow path of the second air stream to the first mixing chamber (28) is closed, and an open position, in which the second air stream can flow into the first mixing chamber (30), wherein the flap (44) is arranged downstream of the heating device (26) and at an inlet opening (27) of the second air guide (24) into the first mixing chamber (28).

A fluid delivery module includes a housing defining a fluid flow path between an inlet and an outlet. The housing includes a top surface portion and a bottom surface portion that are movable to vary a flow direction of a fluid flow along the fluid flow path. The fluid delivery module includes an outlet treatment movable to vary a flow rate of the fluid flow exiting the outlet and a control unit configured to send commands to move at least one of the top surface portion, the bottom surface portion, or the outlet treatment according to a fluid delivery profile that dictates a flow pattern of the fluid flow.

A vehicle-use air conditioning device that supplies air to a side vent aperture portion regardless of a discharge mode, and allows a discharge of air from a defrost aperture portion when a discharge mode that maximizes a ratio of air blown to a passage communicating with a foot aperture portion is employed, is such that a change in an amount of air supplied from the defrost aperture portion is restricted using a simple structure that does not necessitate fine adjustment, even when an air passage on a downstream side of the side vent aperture portion is closed. A passage (a third passage 23) communicating with a side vent aperture portion 17b to a downstream side of heat exchangers 6, 7 is configured of a passage that, when a rotary type first door 25 that adjusts ratios of air blown to a first passage 21 communicating with a foot aperture portion 18 and a second passage 22 communicating with a defrost aperture portion 16 and a center vent aperture portion 17a is in a discharge mode position that maximizes the ratio of air blown to the first passage 21, connects a region to an upstream side of the first door 25 and the side vent aperture portion 17b, regardless of a discharge mode.
