“With the increasing market demand for family cars, many cars have entered the market directly after the production line. There is no release period for the harmful gases and odors of various accessories and materials. The plastic parts, carpets, and roof felts installed in the car If you do not comply with strict environmental protection requirements, it will directly cause air pollution in the car.

In-car air purification market has broad prospects
With the intensification of air pollution and smog in various places, bacteria and viruses are rampant, and air purification has become a hot spot. As a space for people’s daily contact, air purification in the car has also become the focus of attention. In response to this consumer demand, many domestic auto companies are currently taking air purification in the car as a prominent selling point of their products. Relevant experts said that the air purification technology market has broad prospects, and the size of the air purification market in vehicles alone is expected to reach one trillion yuan.
Air pollution in cars is seriously harmful
source of pollutants
1. During the production of vehicles, a large number of plastic products and adhesives are used for interior parts. These are the main culprits of environmental pollution in the car. The solvent used in the adhesive is the main source of pollution in the car.
2. After the engine runs for a long time, not only the heat generated by it will increase the volatilization of pollutants in the car, but also the amine, nicotine and other substances produced by itself will also cause harm to the body of the occupants.
3. Putting some inferior plush toys, cushions and other decorations in the car will increase the release source of “formaldehyde” in the car. Others like to spray perfume in the car. Many perfumes are chemical compounds, which also contain harmful substances, which will only increase the pollution.
4. Automobile exhaust gas. There are about 150 to 200 kinds of exhaust gases after chemical analysis, among which carbon monoxide, hydrocarbons, nitrogen oxides, carbon and other gases and particulate matter are more harmful to human body.
Air pollution in the car not only causes the air in the car to smell unpleasant, but more seriously, some harmful substances may have adverse effects on physical health; in addition, driving in a polluted environment for a long time will cause the driver to dizziness, drowsiness and other adverse effects Reactions, which in turn lead to inability to concentrate, may lead to traffic accidents.
A variety of sensors to achieve air purification system solutions
In an air purification system, a variety of different sensor technologies are required to monitor, purify, and maintain a comfortable, clean, and safe in-car environment. The temperature and humidity sensor HTW-211, PM2.5 particulate matter sensor TF-LP01, PM2.5 PM1.0 sensor GPSM series, VOC air quality sensor TGS2602, etc. provided by Gongcai.com are used in the whole air purification system. Accurate and effective data monitoring of temperature, humidity, particulate matter concentration, volatile organic compound concentration, etc.
When the monitored data exceeds the standard, the system will first command the air conditioning system to use the external circulation to inhale fresh air, and filter pollen, odor and some allergens through the filter element. There is a purifier in the car, which can be linked with the purifier to turn on the purification function.
Intelligent temperature control and humidity control
Install the temperature and humidity sensor HTW-211 near the cockpit in the car, and adjust the dehumidification mode of the air conditioner by detecting the humidity in the cockpit to avoid excessive humidity in the car or drying due to excessive dehumidification. If there is a humidifier in the car, also It can be linked with the humidifier to turn on the humidification function. The HTW-211 temperature and humidity sensor produced by South Korea’s Samyoung has cooperated with Ford Motor. So far, the field defect rate has reached 0ppm. Ford Motor has recognized the quality and durability of South Korea’s Samying HumiChip temperature and humidity sensor, ensuring AEC-Q100 1 level of vehicle reliability. Passed the AEC-Q100 vehicle regulation certification.
There are generally 1-2 temperature and humidity sensors located in the ventilation ducts in the car compartment, which measure the temperature in the car, transmit the signal to the Electronic control unit of the automatic air conditioner, and adjust the car temperature suitable for the human body.
