A method for air conditioning a vehicle seat that is occupied by a person and that comprises at least one seat ventilation system, wherein at least one humidity sensor is arranged in a seat part and/or a backrest part of the vehicle seat as an actual humidity value transmitter for the absolute air humidity within the cushion part of the at least one seat part and/or backrest part so that a target state of comfort for a person seated on the vehicle seat can be accomplished via a control and regulating device through engagement of the seat ventilation system, wherein the target state of comfort can be controlled to a specifiable target humidity limit value through variation of the air flow of the seat ventilation system as a function of at least one control algorithm that evaluates the detected actual measured humidity value.

Methods and systems described perform air cleaning and/or sanitization in a heating, ventilation, air conditioning, and/or refrigeration (HVACR) system by detecting a concentration of airborne contaminants in a space serviced by the HVACR system. The detected concentration of airborne contaminants is determined whether it exceeds a threshold relative to a capacity of a first air cleaner. When the detected concentration of airborne contaminants exceeds the threshold, a second air cleaner is selected and enabled to be activated in the space. When the detected concentration of airborne contaminants does not exceed the threshold, the first air cleaner is selected and enabled to be activated in the space. The first air cleaner has a cleaning material different from the second air cleaner, and the first air cleaner, relative to the second air cleaner, treats the space at a lower concentration of airborne contaminants. The second air cleaner includes specifically designed cleaner modules.

A heat exchange system for a vehicle includes: a heat exchange module disposed at a rear, in a length direction, of a vehicle body, formed of a plurality of plate-shaped plates including a plurality of through-holes; a radiator installed at a front, in the length direction, of the vehicle body; a heating, ventilation, and air conditioning (HVAC) module disposed at the rear, including an air conditioning cases that includes an evaporator, an indoor condenser, and an opening/closing door provided therein; an electric compressor; a rear driving motor disposed at the rear; an autonomous driving controller disposed at the rear; and a switching valve including a first valve installed on a first refrigerant line, a second valve installed on a second refrigerant line; and a third valve installed on a third refrigerant line.

A heat accumulating unit includes an upstream heat accumulator and a downstream heat accumulator each accommodating a supercooling heat accumulating material. Each of the upstream heat accumulator and the downstream heat accumulator has a channel in which fluid flows. In heat accumulation of the supercooling heat accumulating material, the channel of the upstream heat accumulator and the channel of the downstream heat accumulator are set in a serial connection state by a serial connection pipe. In a temperature rise mode, fluid that has passed through the channel of the upstream heat accumulator flows in a bypass pipe.

A fan shroud and a blower device are provided. The fan shroud includes a shroud wall surface and a plurality of ventilation openings. The shroud wall surface extends around a fan along a radial direction orthogonal to a rotation axis. The plurality of ventilation openings are formed through the shroud wall surface in a thickness direction of the shroud wall surface to allow passing of wind generated by a fan motor. A width of a wall surface side opening on a downstream side of the wind in the ventilation opening is smaller than a width of a lateral wall side opening on an upstream side of the wind in the ventilation opening.

A series-hybrid vehicle includes an internal combustion engine for electric power generation and a motor generator for travelling. The internal combustion engine is cooled by a second coolant water circuit that has a main radiator. A first coolant water circuit having a sub radiator is used to cool a front wheel-side power train cooling part, a rear wheel-side power train cooling part, a water-cooled condenser, and a low temperature-side intercooler. When the vehicle is accelerating, an electrical compressor for an air conditioner comes to a stop, and the circulation of refrigerant to the water-cooled condenser is brought to a halt.

This application provide a refrigerant thermal management module and a thermal management system. Components in the refrigerant thermal management module are centrally arranged, so that a pipeline connected between the components is shortened and a refrigerant flow resistance is reduced, improving working performance of a refrigerant loop. In addition, a platform-based design is implemented through modular design. In addition, a plate heat exchanger in the refrigerant loop is used to absorb heat from a coolant loop in a vehicle function module, to implement a function of cooling the vehicle function module; and a condenser in the refrigerant loop is used to release heat to the coolant loop of the vehicle function module, to implement a function of heating the vehicle function module. Regardless of whether the vehicle function module needs to be heated or cooled, refrigerant flows in the refrigerant thermal management module keep a same direction of circulation.

The invention relates to an air outlet structure, a column, and a vehicle. The air outlet structure comprises: an air duct; a first air outlet and a second air outlet, the first air outlet and the second air outlet being configured to be spaced apart from each other and parallel to each other; and a first air-inducing channel and a second air-inducing channel, the first air-inducing channel extending to the first air outlet from the air duct, the second air-inducing channel extending to the second air outlet from the air duct, and the first air-inducing channel and the second air-inducing channel being configured in such a manner that a first airflow flowing out of the first air outlet and a second airflow flowing out of the second air outlet intersect and scatter each other. Through the foregoing air outlet structure, the vehicle according to the invention can expand an air supply range, significantly improve uniformity of air supply, and prevent directly blowing air to a passenger.

According to the present disclosure, a drunk driving prevention system including: an alcohol detection unit configured to detect a driver's inebriation through the breath test device provided in a vehicle; a computation unit configured, when the driver is detected to be in a drunk state by the alcohol detection unit, to compute a driving-possible time at which the drunk state is resolved in the future so that driving is possible; and a notification unit configured to output the driving-possible time or whether or not driving is possible through an infotainment system of the vehicle or a driver's terminal is disclosed.

A thermal management system is provided for a vehicle that includes a traction battery. The thermal management system includes refrigerant and cooling subsystems. The cooling subsystem includes a cabin coolant loop that provides thermal management of a passenger cabin of the vehicle, a battery coolant loop that provides thermal management of the traction battery and a drivetrain coolant loop that provides thermal management of a drivetrain and power electronics of the vehicle.
