Air cleaning and purification are important requirements of passengers. Therefore, the car air conditioner must also ensure that the fresh air delivered in the ventilation process is healthy. This also requires the car air conditioner to purify the input air. This system process is also called air conditioning purification. system.
When a car is driving on a highway, the biggest pollution in the air outside the car is all kinds of suspended dust. Suspended dust is mainly composed of solid particles formed by the crushing of solid materials, harmful gases such as CO, CO2, and SO2 discharged from automobile exhaust, as well as various smoke, pollen, bacteria, etc. Moreover, the circulating air in the car is polluted by human activities and work processes, such as the CO2 exhaled by the human body and the smell of sweat from the body, which affect the health of the human body and reduce the comfort of the air conditioner.
Therefore, the purpose of car air conditioning purification is to remove these harmful gases and dust, so as to maintain a clean and comfortable air environment in the car.
The purification of automobile air conditioners includes two parts, namely, the purification of the outdoor air flowing into the room and the purification of the indoor circulating air.
Dust is the biggest pollutant in the driving process of a car. The air-conditioning purification system purifies the dust in the outdoor air mainly in two forms: filter dust removal and electrostatic dust removal.
1) Filter and remove dust
Filtering and dust removal are actually installed at the air supply and return air outlets of the air conditioning system, mainly to filter dust and other particulate matter.
2) Electrostatic dust removal
The electrostatic precipitator is to install a set of electrostatic precipitator behind the filter of the air inlet. Electrostatic dust removal is the use of high-voltage electrodes to generate a high-voltage electric field to ionize the air to charge the dust particles, and then generate a directional movement under the action of the electric field, and settle on the positive and negative electrodes to achieve filtering and dust removal of the air.
