Proposed is an air-curtain system of a vehicle. The system may include a plurality of air discharge units provided on a roof of a door side or trunk side of the vehicle and adjusting a direction or pressure of discharged air, an air supply system connected at a plurality of ends to the air discharge units and adjusting supply of the air to the air discharge unit as a plurality of guides provided therein are rotated, and a controller adjusting a flow rate of the air discharged from the air discharge unit by adjusting a rotation angle of each of the guides depending on an open or closed state of a door or trunk of the vehicle.

A vehicular air conditioning system includes a cooling heat exchanger and a heating heat exchanger sequentially installed on an internal flow path of an air conditioning case to cool and heat an air blown from a blower, a plurality of air discharge ports configured to discharge cold air and hot air passing through the cooling heat exchanger and the heating heat exchanger into a passenger room, a first bypass flow path configured to allow the air blown from the blower to bypass to an upstream side of the heating heat exchanger before passing through the cooling heat exchanger, and a first opening/closing door configured to open and close the first bypass flow path.

The present embodiments relate to an air distribution apparatus for distributing conditioned airflow from a roof mounted air conditioner to the inside of a vehicle, which includes an inlet port adapted to receive the conditioned airflow from the roof mounted air conditioner. An outlet port, which is disposed adjacent to each longitudinal end of the apparatus, delivers conditioned airflow to the vehicle. An internal supply duct is adapted to evenly split the conditioned airflow to the outlet ports.

The invention relates to a heating, ventilation and/or air conditioning device (10) for a motor vehicle, comprising a housing (12) defining an air duct (11) for the passage of an airflow comprisingan inlet module (8), comprising at least one air inlet (15, 16), an air filter (70) being arranged within the inlet module (8), anda distribution module (9) comprising at least one air outlet (27, 29, 30), the inlet module (8) and the distribution module (9) being detachably assembled to one another; according to the invention, the inlet module (8) is configured to be arranged in a first area of the vehicle, and the distribution module (9) is configured to be arranged in a second area of the vehicle, the air filter (70) being able to be removed from the second area of the vehicle. The invention also relates to a motor vehicle comprising such a device.

An HVAC system that optimized for minimizing the amount of electrical power used during operation at various levels producing cold air or warm air is provided. The system includes an air inlet, a scroll, an air conditioning module, and an air delivery system for various locations within a vehicle that includes the HVAC system.

A thermal management system configured to analyze thermal condition data generated by at least one thermal sensor located in a vehicle of an occupant of the vehicle, and control a flow of conditioned air to the occupant based on the analyzed thermal condition data.
