An embodiment provides a vehicle heating device for heating a vehicle interior through heat radiation or heat convection using a heating unit connected to an air-conditioning casing. Accordingly, the vehicle heating device may improve the performance, efficiency, and quality in heating the vehicle interior through at least any one of heat convection and heat radiation using the heating unit.

A vehicular air-conditioning unit has an air-conditioning case, a first ventilation passage and a second ventilation passage, a first communication-ventilation passage defined in the air-conditioning case, the first communication-ventilation passage through which one end of the first ventilation passage communicates with one end of the second ventilation passage, a first heat exchanger that heats or cools air flowing in the first ventilation passage, a second heat exchanger that heats or cools air flowing in the second ventilation passage, and a blowing mode switching device setting any one of blowing modes. The blowing modes include (i) a first blowing mode in which air is blown into a vehicle compartment after flowing through the first ventilation passage and in which air is blown into the vehicle compartment after flowing through the second ventilation passage and (ii) a second blowing mode in which air flows into the second ventilation passage through the first communication-ventilation passage after flowing through the first ventilation passage and is blown into the vehicle compartment.

A vehicle air conditioning device (10; 10A; 10B) has a casing (20) configuring a temperature adjustment section (12; 12A; 12B). The casing (20) has provided in a position thereof opposed to an inflow surface (41) of a heat exchanger (40) a flow direction change section (30) which causes the flow direction of air led to the temperature adjustment section (12; 12A; 12B) from a duct section (13; 13A; 13B) to bend approximately 90 degrees and leads the air to the inflow surface (41). Guide portions (60, 70; 60A, 70A; 60B) smaller in area than the flow direction change section (30) as seen when directly facing the inflow surface (41) are provided in a heat exchanger upstream space (22) between the inner wall surface of the casing (20) and the inflow surface (41).

An HVAC system including a defrost manifold. The defrost manifold has a first side window outlet, a second side window outlet, and a windshield outlet. A first rib partially obstructs the first side window outlet. A second rib partially obstructs the second side window outlet. A control door is movable to open and close the defrost manifold. A first wall extends from a first portion of the control door that is opposite to the first side window outlet. A second wall extends from a second portion of the control door that is opposite to the second side window outlet. Movement of the control door varies the position of the first wall relative to the first rib, and varies the position of the second wall relative to the second rib, to control airflow through the first and second side window outlets

A heating, ventilation, and air-conditioning (HVAC) assembly for supplying different mixed air flows simultaneously is disclosed. The assembly includes first blend kinematics configured for allowing passage of a first air flow, second blend kinematics configured for allowing passage of a second air flow, obtaining means configured to obtain a temperature command indicating a target temperature for two different locations outside the HVAC assembly, identifying means configured to identify a pattern for the first blend kinematics and the second blend kinematics for modifying the first air flow and the second air flow based on the temperature command, and coordinating means configured to coordinate each of the first blend kinematics and the second blend kinematics simultaneously.

A HVAC system is provided for use in a vehicle. The HVAC system includes a HVAC housing that contains a series of heat exchangers to heat and cool the passenger cabin of a vehicle. A blower fan may be disposed in a blower housing that is connected to the HVAC housing. The blower housing may contain a scroll portion that surrounds the blower fan. A door may be disposed in the scroll portion to adjust the volume of the scroll portion.

An air conditioning system for a vehicle may include a front Heating, Ventilation, and Air Conditioning (HVAC), a rear extension duct for supplying air from the front HVAC to a rear seat, a rear blower disposed in a middle of the rear extension duct to blow air drawn in through the rear extension duct from the front HVAC, a vent duct branched from the rear extension duct to discharge air blown by the rear blower to a rear interior space of the vehicle through a vent grille, a rear floor duct branched from the vent duct to discharge air supplied through the vent duct to the rear interior space, and an air direction adjustment door to adjust a direction of air and a volume of the air for the vent duct extending to the vent grille and the rear floor duct extending to the discharge port, and an actuator thereof.

A ventilation device of a motor vehicle includes a housing having an inlet opening and an outlet opening. A guide unit is arranged between the inlet and outlet openings and includes a number of guide surfaces forming air ducts. A control element arranged between the inlet opening and the guide unit adjusts a volumetric flow ratio of an air flow flowing along the guide unit. The control element has a partially cylindrical air duct body is arranged in the housing such that it can be pivoted about a first pivot axis perpendicular to the inflow direction. A number of slats are coupled to one another and are pivotable about respective second pivot axes perpendicular to the first pivot axis are arranged in the air duct body. The air duct body and the slat unit are adjustable independently of one another by an adjusting unit.

An apparatus ventilates the passenger compartment of a motor vehicle. The apparatus has a source for producing an open or free jet of moving air, and a deflecting body, wherein the deflecting body is spaced apart from the source and one of the surfaces of the deflecting body is, according to the designated use, an impact face against which the open jet impinges, and the impact face is a deformable face which is integrated steplessly into a surrounding surface.

Disclosed is an HVAC system configured to reduce noise. The HVAC system includes a door having a first and second end. The door includes an elastomer along the first end and a rotatable member adjacent the second end. The elastomer includes a door touch area. The case defines an internal case portion, external case portion, and a case opening fluidly connecting the internal and external case portion. The case is configured to receive the rotatable member of the door such that the door is rotatable about an axis between a first position, where the door covers the case opening, and a second position, where the door does not cover the case opening. The case includes a case touch area with a graining. The door touch area and the case touch area are substantially parallel and in contact along a surface contact area when the door is in the first position.
