An air purification device for a vehicle includes: a sorption device provided with a sorbent; an air intake duct for sucking air in a vehicle cabin; an outlet-side three-way valve connected to the sorption device; an air supply duct for blowing air into the cabin; an exhaust duct for discharging air to outside of the cabin; a blower; a heater; and a controller. The controller selectively executes a purification mode in which air in the cabin is sent into the sorption device at a purification temperature, and purified air from which moisture and carbon dioxide have been removed by the sorbent is blown into the cabin, and a first regeneration mode in which air heated to a first regeneration temperature is sent into the sorption device, and exhaust air containing moisture and carbon dioxide released from the sorbent is discharged to the outside of the cabin.

An air conditioning device for a vehicle includes a first flow path through which air subject to dehumidification flows, a second flow path through which air for recovery flows, a desiccant part and a controller. The desiccant part is fluidly communicated with the first and second flow paths, and configured to adsorb moisture contained in the air subject to dehumidification, and to discharge the moisture to the air for recovery. The controller is configured to control an air volume of the air subject to dehumidification and an air volume of the air for recovery so that the air volume of the air for recovery is less than the air volume of the air subject to dehumidification, after the air volume of the air for recovery reaches a prescribed air volume for achieving a target dehumidification amount of the air subject to dehumidification.

A flow channel located downstream of a temperature regulating device branches off into a first flow channel and a second flow channel. In the first flow channel, a windshield's-side flow channel connecting to a windshield's-side air outlet port and an adsorbent's-side flow channel connecting to an adsorbent inflow section are formed. At the time of regeneration treatment of an adsorbent, by interrupting communication between the first flow channel and the second flow channel, interrupting communication between a temperature regulating device outflow section and the windshield's-side air outlet port, and making the temperature regulating device outflow section and the adsorbent inflow section communicate with each other, the air warmed by the temperature regulating device is preferentially guided to the adsorbent.

A bottle for a heat exchanger extending in a longitudinal direction, including a tubular main body comprising a first opening, a plug having a plug body inserted at least partially into the tubular body to close the first opening, a retaining element adapted to retain the plug with respect to the tubular main body after insertion of the retaining element into the tubular main body, wherein the plug comprises a guiding means adapted to guide the retaining element during insertion of the retaining element and the retaining element is configured to be locked in the tubular body, the retaining element and the plug cooperating together to retain the plug in the tubular main body along the longitudinal axis.

The invention relates to a nebulizer system (10) for a motor vehicle, having at least: a tank (12) for a liquid, a nebulizer chamber (14), said nebulizer chamber (14) having a nebulizer nozzle (22) provided with an acoustic wave output device configured such that said liquid from said tank (12) for the liquid forms a mist of droplets of said liquid, said mist being intended to pass into a passenger compartment of the motor vehicle, and a filter system (16) capable of filtering said liquid contained in said tank (12) for the liquid before it passes into said nebulizer chamber (14). According to the invention, said nebulizer system (10) has an input module (26) for air, said inlet module (26) for air having an air injection volute (30) capable of channelling the air in the direction of the internal volume of said nebulizer chamber (14). Application in particular to the automotive field.

A vehicle air-conditioning system includes a cold-air circulation section in which indoor air of a vehicle is cooled via heat exchange with a refrigerant and is again supplied to a passenger compartment, a hot-air circulation section in which the indoor air is raised in temperature via heat exchange and is then again supplied to the passenger compartment, a purification circulation section in which the indoor air is introduced and purified and is then again supplied to the passenger compartment, and a refrigerant circulation section in which the refrigerant circulates to undergo heat exchange with the cold-air circulation section and the hot-air circulation section. The vehicle air-conditioning system separates an indoor air flow-path from an outdoor air flow-path to block outdoor air when performing air conditioning, and performs air conditioning of the passenger compartment using only the indoor air without entry of the outdoor air.

A blower case for a heating, ventilation, and air conditioning (HVAC) system. The blower case includes an inlet for airflow entering the blower case. Also included is a dehumidifier, which is movable between a first position and a second position. In the first position the dehumidifier is in a path of airflow entering the blower case through the inlet. In the second position the dehumidifier is not in the path of airflow entering the blower case through the inlet.

A humidifying device has an adsorption module and a blower. The adsorption module has the adsorbent. The adsorption module is configured to adsorb the water from the air passing through the adsorption module to the adsorbent and is configured to desorb the water from the adsorbent to air passing through the adsorption module. The blower blows the air to the adsorption module. The blower, in an adsorption operation in which the adsorbent adsorbs the water from air, draws the air from a roof space and blows the air to the adsorption module whereby the adsorption module adsorbs the water from the air. The roof space is defined between a vehicle ceiling panel and a ceiling interior member.

A blower case for a heating, ventilation, and air conditioning (HVAC) system. The blower case includes an inlet for airflow entering the blower case. Also included is a dehumidifier, which is movable between a first position and a second position. In the first position the dehumidifier is in a path of airflow entering the blower case through the inlet. In the second position the dehumidifier is not in the path of airflow entering the blower case through the inlet.

A humidifying device includes a casing that defines a first air passage that guides air to an adsorbent module accommodation portion accommodating an adsorbent module including an adsorbent, and a second air passage through which the air flowing out of the adsorbent module accommodation portion flows. The humidifying device includes a peltier device that has a heat absorbing side and a heat generating side generating heat due to heat transfer from the heat absorbing side. The peltier device is housed in the casing such that the heat generating side is located in the first air passage and the heat absorbing side is located in the second air passage.
