The invention relates to an air cooling device (1) for a vehicle, notably a motor vehicle, comprising:at least a reserve (3) of liquid, a device (5) for nebulizing the liquid, at least two air outlets (7) for diffusing at least an air flow (F1, F2) intended for the interior of the said vehicle, andat least two nebulizing ducts (9) respectively intended to have passing through them an air flow (F1) laden with droplets of nebulized liquid, each nebulizing duct (9) being arranged in fluidic communication with the reserve (3) of liquid and with an associated air outlet (7). According to the invention, the air cooling device (1) comprises at least one nebulizing regulating member (19) to regulate the flow rate of the air flow (F1) laden with droplets of nebulized liquid passing along a nebulizing duct (9) and to be diffused through the air outlet (7) associated with this nebulizing duct (9).

A vehicle climate control system includes a heating, ventilation, and air conditioning (HVAC) system where condensate from the system is conveyed to a misting device disposed at an air-conditioned outlet in the cabin of the vehicle. The misting device can be arranged at the exit of the air-conditioned outlet such that conditioned air is conveyed by the HVAC ducting and mixes with the mist generated by the misting device at the air-conditioned outlet. The mist may be scented using an injection device that pumps a fragrant fluid into the misting device along with the condensate. Prior to conveying the condensate to the misting device, the condensate may be pumped through bacteria and sediment filter media providing a clean supply of condensate to the misting device. Positioning the misting device at the air-conditioned outlet helps prevent mold or debris from being trapped in the HVAC system or ducting.

It is proposed to arrange a plurality of individual separator elements (48, 49) on the first side (40) of the membrane (38) in order to provide a humidifier (37) with integrated water separator, in particular for fuel cells (11) having a water vapor permeable membrane (38) and separator elements (48, 49) for separating water, wherein the membrane (38) on a first side (40) is in contact with a first channel (41) for a first humid gas stream, and on the second side (42) is in contact with a second channel (43) for a second, dry gas stream to be humidified, which allows an optimized exchange of moisture between the exhaust gas and operating medium streams of a fuel cell. Also provided is a fuel cell system and vehicle having the aforementioned humidifier.

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 dust reduction device for a vehicle includes an inlet aperture for receiving airflow created as a result of forward movement of the vehicle. The dust reduction device provides a primary airflow path leading from the inlet aperture to a vehicle opening, and a secondary airflow path leading from the inlet aperture to a ventilation exit. During forward movement of the vehicle, the primary airflow path is substantially blocked by airflow from the secondary airflow path such that airflow from the primary airflow path is provided to the vehicle opening and into the vehicle thereby minimising dust ingress in the vehicle.

A vehicle air conditioner has a bypass pipe which passes a radiator, an outdoor expansion valve, and opening/closing valves. A controller is configured to execute a heating mode to open a first solenoid valve and close a second solenoid valve, and a dehumidifying and heating mode to close the first solenoid valve, open the second solenoid valve, let a refrigerant radiate heat in an outdoor heat exchanger, let the refrigerant absorb heat in a heat absorber, and generate heat in an auxiliary heater. When changing from the heating mode to the dehumidifying and heating mode, the controller sends the refrigerant to a receiver drier, controls a compressor to reduce a difference between pressures before and after the second solenoid valve, opens the second solenoid valve, closes the first solenoid valve, shuts off the outdoor expansion valve, and shifts the compressor to control in the dehumidifying and heating mode.

Sun load on a cabin of a vehicle is determined without a sun load sensor by affixing a relative humidity/temperature sensor to an inside of a windshield of the vehicle. The relative humidity/temperature sensor includes a relative humidity sensor that senses relative humidity of air at the relative humidity sensor, a temperature sensor that senses temperature of the air at the relative humidity sensor and a glass temperature sensor that senses temperature of glass of the windshield. A controller determines the sun load based on readings from the relative humidity/temperature sensor of relative humidity of the air at the relative humidity sensor, temperature of the air at the relative humidity sensor and temperature of the glass of the windshield.

A heating, ventilation, and air conditioning (HVAC) system may comprise an evaporator core including an upstream inlet face in which humid air is received, a downstream outlet face from which dehumidified air is discharged, and a plurality of air-contacting surfaces extending between the inlet and outlet faces. In one form, an antimicrobial coating may be formed on the air-contacting surfaces of the evaporator core. The antimicrobial coating may comprise an ionic material having immobilized ionic groups of one type of charge and mobile counterions of another type of charge. The mobile counterions may be ionically associated with the immobilized ionic groups. In another form, an ultraviolet light emitting diode (UV-LED) may be used to direct UV light onto the air-contacting surfaces of the evaporator core.
