Air conditioning system for multi-zone air conditioning of a motor vehicle interior comprising a casing with a mixing chamber and several zone outlets outgoing from mixing chamber, in which an evaporator and at least one heat exchanger are disposed such that main air flow from evaporator through at least one heat exchanger into zone outlets is linear and at least two bypass channels, each comprising a louver, in order to circumvent at least one heat exchanger connect a region downstream of evaporator and a region downstream of at least one heat exchanger, wherein the first bypass channel, as a mixing bypass channel, opens out into mixing chamber and the second bypass channel, as a stratification bypass channel, opens out into a zone outlet.

The invention proposes a method for recovering a liquid collected on an interior or exterior surface (1, 19) of a motor vehicle bodywork (17) or glazing (2) element, characterized in that it consists in analysing a quantity of the collected liquid stream using a device (30) for measuring or estimating a parameter indicative of a state of pollution of the collected liquid, such as its turbidity, in comparing a measured value of the turbidity against a threshold value and, when the measured value is below the threshold value, in directing the collected liquid stream towards a recovery unit (9) or, when the measured value is above the threshold value, in discharging the collected liquid stream, for example in the form of waste.

Provided is a register that can more surely suppress abnormal noise caused by air passing through a space between a damper and a retainer. An inner wall of an upper side wall of the retainer is formed with a plurality of rib parts provided on a downstream side relative to an outer periphery on the downstream side of a plate member in a closed state of a damper. The plurality of rib parts is arranged in a direction parallel to a turning axis of the damper, and adjacent rib parts are formed into different shapes. A soft seal member is provided with a plurality of protrusion parts on an upper surface of the outer periphery on the downstream side of the plate member.

A vehicle front arrangement structure includes high-voltage equipment, air conditioning equipment that includes an air-conditioner blower, and a high-voltage connector part. The high-voltage equipment and air conditioning equipment are arranged in front of a vehicle. The high-voltage connector part is provided at a vehicle rearward end portion of the high-voltage equipment to connect a high-voltage wire harness. The high-voltage connector part is arranged so as to be displaced in at least one of a vertical direction and a horizontal direction as viewed from the front of the vehicle.

A heat conducting device in a vehicle whereby heat in the body or shell of the vehicle is transferred to the ground includes a control device, a heat transferring device, and a driving device. The heat transferring device is in the vehicle and is connected to the shell of the vehicle when the vehicle is flameout, the driving device is coupled to the control device and the heat transferring device, such that the heat transferring device is extended downwards from the vehicle, until the heat transferring device contacts the ground, thereby heat of the shell of the vehicle is transferred to the ground.

A ventilation device for an interior of a motor vehicle includes a ducting system with at least one air duct and a blower via which an air flow can be generated in the ducting system. To allow active ventilation of the interior at particularly low noise levels, at least one sound transducer of the ventilation device is provided via which a sound pressure in the ducting system can be detected and a signal corresponding to the sound pressure detected can be transmitted to at least one second sound transducer of the ventilation device. In order to reduce the sound pressure, a counter sound pressure depending on the signal in the ducting system can be generated by the at least one second sound transducer.

Methods and systems are provided for a deflector. In one example, a system includes a first engine bay component comprising a deflector with a deflection surface shaped to engage a second engine bay component to rotate the first engine bay component and mitigate contact between the first engine bay component and a third engine bay component.

The invention relates to an electric fan set, notably for a motor vehicle heating, ventilation and/or air conditioning installation, comprising: a motor, a motor support (11), and a control module support (23) forming a bearing support for the motor. According to the invention, the motor support (11) and the control module support (23) each comprise at least one fixing zone, the fixing zones being able to cooperate with one another for the assembly of the motor support (11) with the control module support (23), according to at least two different positions of the motor support (11) relative to the control module support (23).

The present invention relates to a modular way to build a rolling chassis using composite materials without custom forming, and yielding appropriate weight distribution (centre of gravity) and torsional and bending rigidity.

A vehicle air conditioner includes: a refrigerant circuit which includes a compressor, an external heat exchanger, an expansion valve, and an evaporator; and a cooling fan. The vehicle air conditioner further includes: a refrigerant temperature detection part; a vehicle environment temperature detection part; and a controller. The refrigerant temperature detection part is configured to determine the temperature of a refrigerant which flows into the expansion valve. The vehicle environment temperature detection part is configured to determine a temperature outside the refrigerant circuit under an installation environment. The controller is configured to control a speed of the cooling fan in a cooling operation time such that a cooling performance with respect to the external heat exchanger is decreased when the temperature difference between a determined refrigerant temperature by the refrigerant temperature detection part and a determined external temperature by the vehicle environment temperature detection part is equal to or less than a first set temperature difference.
