A method of maintaining a position of an airflow-direction control element 16 of a HVAC system, comprising the steps of, a] determining a position of at least one movable member of an airflow-direction control mechanism of the HVAC system; and b] calculating whether the movable member is at a target position associated with a required position of the airflow-direction control element, and if not, activating an airflow-direction-controller actuator of the HVAC system to effect a change in the position of the movable member thereby bringing the airflow-direction control element to or towards the said required position. A HVAC system suitable for implementing such a method is also provided and capable of improving the overall efficiency of operation.

A vehicle cabin airflow forming device includes an airflow forming unit. The airflow forming unit is configured to form airflows circulating around seating space of a seat and form, as part of the airflows, an ascending airflow on one lateral side of the seating space, and a descending airflow on the other lateral side of the seating space. The seat is provided inside a vehicle cabin, and the airflows circulate around the seating space as viewed from a front side of the seat.

Some embodiments provide a vehicle climate control system for controlling climate conditions in various cabin regions of a vehicle cabin, where the climate control system is configured to control one or more vehicle components to change the set of climate conditions associated with one or more cabin regions to approximate a set of optimal comfort conditions. The climate control system controls various vehicle components to control climate conditions, including window assemblies, sunroof assemblies, etc. The climate control system determines optimal comfort conditions which optimize perceived temperature of various occupant body parts and maintain various climate characteristics within one or more sets of thresholds. Output configurations of various vehicle components can be determined based at least in part upon determined optimal comfort conditions of various cabin regions. Output configurations can be generated based at least in part upon various control mode priorities.

A system and method are provided for an air vent system in, for example, a vehicle. The air vent system is configured to direct air flow to a point relative to a user's position in the vehicle. A camera may capture a view of the user and processing circuitry may analyze the captured information to determine a position of the user in the vehicle and control the direction of air flow based on the determined position of the user.

A vehicle air-conditioning device includes: an air-conditioning device having an all-seat air-conditioning mode in which air-conditioned air is blown out to occupants of all seats in a vehicle cabin and an individual air-conditioning mode in which the air-conditioned air is blown out to some of the occupants of all seats; a selection device used to select the all-seat air-conditioning mode and the individual air-conditioning mode; and a controller configured to control the air-conditioning device in an air-conditioning mode selected in the selection device. When the vehicle is activated by a remote starter device configured to remotely activate the vehicle, the controller controls the air-conditioning device by switching the air-conditioning mode to the all-seat air-conditioning mode even when the air-conditioning mode selected at previous turning-off of an ignition device is the individual air-conditioning mode.

It is provided an interior adjustment system for a vehicle, comprising a first interior assembly which has a first adjustment device for adjusting the first interior assembly, at least one second interior assembly which has a second adjustment device for adjusting the at least one second interior assembly and a controller. The controller is designed to activate the second adjustment device in order to adjust the at least one second interior assembly as a function of an adjustment movement of the first interior assembly.

Various disclosed embodiments include illustrative devices, systems, and vehicles for heating, ventilation and air conditioning (HVAC) functions for an area remote from an HVAC system. In an illustrative embodiment, a device includes a seat having a first section of duct having a first end, a second section of duct couplable to the first section of duct, and a third section of duct couplable to the first section of duct. The second section of duct connects at a first end to an air supply source and at a second end to the first end of the first section of duct. The third section of duct includes an exhaust vent configured to direct air received from the air supply source in a direction aft of the seat.

A method of air pollution filtration in a vehicle is disclosed. A plurality of purification devices are provided to detect and transmit an inside-device gas detection datum, respectively, for intelligently selecting and controlling the activation of filtering the air pollution in the inner space of the vehicle. An in-car gas exchange system and a connection device are provided. The connection device receives and compares the respective inside-device gas detection datum, and selectively transmits a control instruction to drive the in-car gas exchange system and the purification devices. The movement of the air pollution is accelerated by the gas convention of the in-car gas exchange system, so that the air pollution is directionally moved toward the corresponding one of the purification devices adjacent to the air pollution for filtration. The air pollution in the inner space of the vehicle is filtered rapidly, so as to provide clean, safe and breathable air.

An air-conditioning vent structure includes a duct portion supported by a duct panel, the duct portion including first and second outlets formed at an upper portion thereof and separated by a partition, and a curvature portion including a curvature, a sliding door slidable along an upper portion of the curvature portion at a lower end portion of the partition, the sliding door including a hole to adjust opening widths of the first and second outlets in accordance with a degree of sliding, a driving portion connected to the sliding door at a lower end portion of the duct panel and configured to apply driving force to the sliding door so that the sliding door slides in opposite directions, and a controller electrically connected to the driving portion to perform a control operation to allow the sliding door to slide in opposite directions in accordance with a use mode.

The present invention relates to a blower unit of an air conditioner for a vehicle, which can effectively prevent water from being introduced into a motor and has a motor housing and a blower wheel improved to smoothly perform cooling of the motor. The blower unit of a two-layered air conditioner for a vehicle, which can divide and inhale indoor air and outdoor air, includes: a scroll case having an upper passageway and a lower passageway; a first blower wheel disposed in the upper passageway; a second blower wheel disposed in the lower passageway and arranged below the first blower wheel; a blower motor for rotating the first blower wheel and the second blower wheel; and a motor housing for covering the blower motor, wherein a hub for guiding air is disposed on the second blower wheel, and the hub of the second blower wheel is partially overlapped with an end portion of the motor housing.
