The invention relates to a nebulizer system for a motor vehicle, which is arranged to be fluidly connected to a liquid storage reservoir, which is called a cartridge, the nebulizer system including: a tank, a nebulizer component producing a mist intended to penetrate a passenger compartment of the motor vehicle, a channel for circulation of the liquid from the cartridge to the tank, and a channel for circulation of air between the cartridge and the nebulizer system.

A heater element including a honeycomb structure and a functional material-containing layer, wherein the honeycomb structure has an outer peripheral wall and partition walls provided inside the outer peripheral wall, the partition walls partitioning a plurality of cells that form flow paths extending from an inlet end surface to an outlet end surface, and at least the partition walls are made of a material having PTC characteristics, and wherein the functional material-containing layer is provided on a surface of the partition walls, and a thickness of the functional material-containing layer increases from the inlet end surface toward the outlet end surface.

In the application, since the flow of air outside the vehicle compartment flowing through the upstream heat exchange part and the flow of air outside the vehicle compartment flowing through the downstream heat exchange part are opposite flows, a second heat exchanger through which the air outside the vehicle compartment flowing from the first fan through the downstream heat exchange part flows, a first heat exchanger is an orthogonal heat exchanger, the second heat exchanger that is a component of a refrigeration cycle execution system, the air in the vehicle compartment, which flows in from the inside air inlet by the rotation of the second fan and is discharged from the outlet outside the vehicle through the first heat exchanger, and the air outside the vehicle compartment, are exchanged with the first heat exchanger, it can be miniaturized along with the improvement of electricity cost.

A system is for preventing molding on an evaporator associated with a vehicle air conditioning system for supplying conditioned air to a vehicle passenger cabin. The system includes a blower for selectively directing airflow over the evaporator and a controller for controlling the blower based on a sensed humidity adjacent the evaporator. The controller may also control a pump for circulating warm coolant from an engine cooling system to a heater core to warm the airflow directed to the evaporator by the blower, and thus contribute to the drying provided. Related methods are also disclosed.

The invention relates to a heating, ventilation and/or air-conditioning device (1) for a motor vehicle, characterised in that it comprises at least one first air circulation channel (3), at least one second air circulation channel (4), and means (5, 6) for generating an air stream in the first air circulation channel (3) and/or in the second air circulation cannel (4), the device (1) also comprising means for the inflow of a cleaning product (13, 16) ending in the first air circulation channel (3) and/or in the second air circulation channel (4).

The present disclosure relates to a method for pretreating an evaporator for accelerating odor reproduction of an odor reproduction device for a vehicle air conditioning system, and a method for pretreating an evaporator surface of the present disclosure may include: a step of preparing an inoculation of malodorous microorganisms; a step of preparing and pretreating an evaporator; and a step of immobilizing malodorous microorganisms on an evaporator surface.

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.

A method of preventing air pollution in a vehicle is disclosed. Firstly, an out-car gas detection device, an in-car gas detection device and a purification device are provided to detect the air pollution and transmit a respective gas detection datum to a connection device. An in-car gas exchange system is provided for intelligently selecting and controlling a gas outside the vehicle to be introduced or not introduced into the inner space of the vehicle. The connection device receives and compares the gas detection data, so that the connection device selectively transmits a control instruction to the in-car gas exchange system and the purification device, and the air pollution in the inner space of the vehicle is exchanged and filtered, so as to provide clean, safe and breathable air.
