Disclosed embodiments include airflow systems, vehicles, and controllers of airflow units. An illustrative airflow system of a vehicle includes an airflow inlet duct, an airflow intake duct, an air intake door, and an airflow unit. The airflow inlet duct is adapted to draw ambient air. The airflow intake duct is adapted to receive airflow from the airflow inlet duct. The air intake door is positioned therebetween. The airflow unit includes a controller configured to close the air intake door and seal off the air intake duct from the airflow inlet duct in response to receipt of at least one signal indicating at least one condition chosen from 1) a presence of water in the airflow inlet duct, 2) a hood of the vehicle being in an open condition, 3) a presence of rain received from a precipitation sensor, and 4) activation of a predetermined speed setting of a windshield wiper.

A vehicle includes an integrated controller equipped with an advanced driver assistance system (ADAS). An air conditioner is configured to introduce air into the inside of the vehicle and to adjust a flow of the air. The air conditioner is configured to transmit the air to the integrated controller by branching an air conditioning duct that is a passage for transmitting air into the inside of the vehicle.

A vehicle control device that controls an air conditioning device and a battery in a vehicle that uses a coolant of the air conditioning device that cools a vehicle cabin for cooling the battery, the vehicle control device including: an air conditioning load determination unit that determines whether the air conditioning device is driven by a predetermined load or more; and a battery input-output control unit that controls at least one of an input power or an output power of the battery. When the air conditioning device is driven by the predetermined load or more, at least one of the input power or the output power is restricted without cooling the battery.

The invention concerns a control module (15) of a blower for a heating and/or ventilation and/or air conditioning device, in particular for a motor vehicle, the blower being configured to generate an airflow, and the control module (15) being configured to control the blower and comprises a heat sink (157), a heat dissipation base (158) and at least one active power electronic component (153) mounted on the heat dissipation base (158). According to the invention, the heat sink (157) comprises a housing (156) for receiving at least a part of the heat dissipation base (158). The heat sink base (158) is mounted by press-fitting into said housing (156). The invention also relates to a corresponding heating and/or ventilation and/or air conditioning device.

A fluid delivery module includes a housing defining a fluid flow path between an inlet and an outlet. The housing includes a top surface portion and a bottom surface portion that are movable to vary a flow direction of a fluid flow along the fluid flow path. The fluid delivery module includes an outlet treatment movable to vary a flow rate of the fluid flow exiting the outlet and a control unit configured to send commands to move at least one of the top surface portion, the bottom surface portion, or the outlet treatment according to a fluid delivery profile that dictates a flow pattern of the fluid flow.

A vehicle-use air conditioning device that supplies air to a side vent aperture portion regardless of a discharge mode, and allows a discharge of air from a defrost aperture portion when a discharge mode that maximizes a ratio of air blown to a passage communicating with a foot aperture portion is employed, is such that a change in an amount of air supplied from the defrost aperture portion is restricted using a simple structure that does not necessitate fine adjustment, even when an air passage on a downstream side of the side vent aperture portion is closed. A passage (a third passage 23) communicating with a side vent aperture portion 17b to a downstream side of heat exchangers 6, 7 is configured of a passage that, when a rotary type first door 25 that adjusts ratios of air blown to a first passage 21 communicating with a foot aperture portion 18 and a second passage 22 communicating with a defrost aperture portion 16 and a center vent aperture portion 17a is in a discharge mode position that maximizes the ratio of air blown to the first passage 21, connects a region to an upstream side of the first door 25 and the side vent aperture portion 17b, regardless of a discharge mode.

The present invention relates to an air conditioner for a vehicle, which can send air-conditioned air toward a rear seat of the vehicle in order to perform air-conditioning of a front seat of the vehicle and air-conditioning of a rear seat. The air conditioner includes an air passageway formed in an air-conditioning case, wherein the air passageway includes: a rear seat cold air passageway which is a passageway that the air passed through the heat exchanger for cooling bypasses the heat exchanger for heating and flows toward a rear seat of the vehicle; and a warm air passageway which is a passageway that the air passed through the heat exchanger for cooling passes through the heat exchanger for heating and flows toward a front seat or the rear seat of the vehicle. The air conditioner includes a rear seat temperature adjusting door for controlling an amount of air flowing from the warm air passageway to the rear seat air outlet and an amount of air flowing from the rear seat cold air passageway to the rear seat air outlet.

A portable air purifier may include a case having an accommodation space, a front side and a rear side of which are open; a fan assembly accommodated in the accommodation space and including a blower fan; a fan cover disposed in front of and coupled to the fan assembly in the accommodation space; and a filter module disposed behind the fan assembly in the accommodation space. The case may include a first support surface that protrudes from an inner circumferential surface of the case and disposed behind the fan cover to face the fan cover, and a second support surface that protrudes from the inner circumferential surface of the case and disposed in front of at least a portion of the filter module to face the at least a portion of the filter module. The fan cover and the filter module may be coupled in a frontward-rearward direction with the first support surface and the second support surface interposed therebetween and may be fixed to the case.
