With the aggravation of air pollution and haze around the media reports into the public eye, air purification has become a hot topic of social public opinion. And the car as People\'s Daily contact with frequent space, interior air purification has become the focus of attention. In view of the trend that consumers pay more and more attention to the health status of themselves and their families (especially the elderly, children and pregnant women), the air purification function in the car will be

1. Business needs analysis:

1. National motor vehicle ownership:

The Transportation Administration of the Ministry of Public Security announced on the 3rd that in the first half of 2019, the number of motor vehicles nationwide reached 340 million, with 12.42 million newly registered vehicles and 14.08 million newly licensed drivers. As of June 2019, the national car ownership reached 250 million, and private cars reached 198 million. 12.42 million vehicles were newly registered

Automobile consumption upgrade:  

According to Nielsen's "2015 Auto Consumption Demand Change Review and New Year Trend Outlook" survey report, the data shows that the family's car purchase budget is mostly concentrated in 80,000-180,000 yuan, and the intention of sedan, hatchback and small SUV relatively high degree.

With the upgrading of new cars and the continuous improvement of purchasing power, consumption upgrades drive the growing demand for high-end products. According to the data from the Federation of Passenger Transport Associations, the average selling price of the overall passenger car has gradually risen from 142,000 yuan in 2011 to 151,000 yuan. In different price ranges, the proportion of sales of models of 100,000 yuan and below fell from 39% five years ago to 32% in 2015, and the proportion between 100,000 and 200,000 yuan increased from 42% to 49%.

For car brands, breakthrough innovation is an important way to help brands achieve high-end. Today, when consumption upgrade has become an important trend, high-quality models with unique functions will win the favor of more consumers on the road of high-end.

3. In-car AIR pollution:

The use of plastic materials in vehicles has rapidly increased from 20 kg per vehicle in the 1990s to about 100 kg per vehicle today. The report of the testing agency shows that more than 90% of the cars contain toxic and harmful gases such as benzene, xylene, and formaldehyde, which seriously exceed the national indoor air quality standard.

Comprehensive analysis, there are three main types of air pollution sources in the car:

Particulate matter (that is, the PM2.5 problem that people are concerned about now);

Microorganisms, bacteria and viruses;

Toxic and harmful gases (such as formaldehyde, ammonia benzene and other chemicals)and various unpleasant odor gases.

Analysis one by one:

Due to the relatively closed environment in the car, although the problem of  is currently the most concerned by the public, it is not the most serious pollution source. Most car air inlets generally have air filters, which are relatively easy to solve technically;

In fact, it is the most harmful source of pollution to the physical and mental health of the people in the car , especially

The car is on a congested road full of car exhaust, and there is a high concentration of exhaust outside the car. The windows are rarely opened in the four seasons. The closed and narrow space inside the car is wrapped with decorative materials (new cars are more serious), emitting all kinds of harmful gases. The Venerable Master smokes or smells from the body, and many people exhale exhaust gas. The air quality in the car can be imagined. People spend most of the day in the office, home,

and car in such a space, and the driver 's time will be longer;

Therefore, we are facing very bad air quality and environment inside the car. Solving the air quality problem in the local environment is far more complicated and difficult than solving the problem of heat and cold. This is also a cutting-edge and difficult .

4. Market demand analysis:

As media reports such as the aggravation of air pollution and smog in various places have entered the public eye, air purification has become a hot topic of socialized public opinion. As the car is a space that people frequently come into contact with every day, air purification in the car has also become the focus of attention. In view of the trend that consumers pay more and more attention to the health of themselves and their families (especially the elderly, children and pregnant women), the air purification function in the car market will become the most powerful selling point in the market share competition.

At present, the system-level products that comprehensively solve the problem of air quality in vehicles are still blank at home and abroad. A survey shows that at present, more than 95% of the products in the domestic car air purification field use activated carbon adsorption technology, which is basically similar to the miniaturization of household air purification systems and transplanted into the car, and the quality of the products varies.

Most of the products currently on the market in this field adopt the technical principle of filtering (physical screen filtering, or electrostatic collection filtering); some use the addition of photocatalysts, UV lamps, negative ions, etc. The difference between products is only in the process , There are many articles on the appearance, most of which are at the level of conceptual rendering. The use of these techniques, from a scientific basis, often results in extremely limited results.

From the perspective of marketing, the product homogeneity in the current car air purification market is serious (technical point of view), and the competition of various manufacturers is more about the soft power of brand influence, product packaging and channel sales, rather than technological innovation. Solve the real pain points of market demand.

2.  Aerospace HTC  core technology introduction:  

1. The plasma light introduction of body air purification technology:

Photoplasma is a gas containing ions and free electrons generated by ultraviolet rays of a specific wavelength. Ultraviolet light and its plasma in the purification system decompose oxygen and water vapor molecules into ozone, hydroxide, free oxygen atoms and other oxides. These molecules are very active and can decompose and convert harmful substances in the air into CO 2 and water and other harmless substances.

Light plasma air purification technology decomposes microorganisms (bacteria and viruses) in the air, removes odors, and generates negative ions to freshen the air without secondary pollution, which is harmless to the human body.

At present, compared with ultraviolet disinfection technology, ozone disinfection technology, negative ion purification technology, photocatalyst purification technology, etc., optical plasma purification technology has a very strong, rapid, long-term and active sterilization and disinfection effect, which can kill a variety of stubbornness in the air. Bacterial viruses (such as bird flu, Ebola, SARS , and most other highly harmful viruses ).

It can effectively remove all kinds of odors in the air, and it is not harmful to humans and animals.


2. Aerospace HTC  optical plasma purification technology advantages:

According to the technical principle of optical plasma purification and degradation, compared with other traditional purification technologies, this purification method is fast and efficient, and the purification result has no residue. In summary, optical plasma purification has the following advantages:

Fast: 500-1000 times faster than traditional technology purification

Comprehensive: dual-band ultraviolet rays and a variety of oxidizing components work together to remove pollutants comprehensively

Active: The light plasma swims divergently and spreads throughout the space without leaving any dead ends.

Safety: The optical plasma composition is pure and free of secondary pollution, and the concentration of active oxygen is safe and controllable

Energy saving: home and office series work continuously for 96 hours and consume 1 kWh of electricity

Green: purification products without secondary pollution, green and environmental protection

Economic: no consumables design, no maintenance, core components can work efficiently and stably for a long time

Space: Compared with other technologies, the purification efficiency is higher without the need for a large space and volume.

3. Introduction to the research and development background of Aerospace HTC   optical plasma technology:

Aerospace Hongda has been engaged in the research of optical plasma technology (also belonging to the field of ultraviolet technology, with slight differences in practical application) for more than ten years; Products Based on this technology, such as ultraviolet Radiation Light Cleaning machine (with Invention Patents), vehicle and household air purification systems (utility model Patents), oil fume purification equipment, water treatment, and various photochemical application products; the core components of the optical plasma tube, and its supporting special drive power supply have a number of patented technologies, and the products are mainly exported to Europe and the United States.

Aerospace HTC   has entered the technology research and development of air purification systems loaded in mobile vehicles since 2013:

Air purification equipment for subway cars (cooperation with Shanghai xx Rail Vehicle Air Conditioning Co., Ltd.);

The passenger car has cooperated with Great Wall Motor for nearly half a year, mainly for the front installation (involving the air conditioning system of the whole vehicle), and the semi-front-mounted air purification equipment (we define the air purification of the armrest box as semi-front-mounted - because it is related to the structure of the whole vehicle relatively independent);

In 2014, BAIC bid for the semi-pre-installation project. With our optical plasma technology solution, it defeated three companies from South Korea, Taiwan and the United States to win the bid;

In terms of business model, Shenzhen Hangsheng chose to cooperate with us - the design and production of the whole machine is undertaken by Shenzhen Hangsheng (including the shell, fan, filtration, negative ion system, etc.), and our company provides the most technically competitive system for this system. The core component - optical plasma assembly (optical plasma tube and supporting drive power supply);
the final product of this solution has been actually applied to some configuration products of BAIC Hyundai IX35 models.

3. Horizontal comparison of advantages and disadvantages of different purification technologies:

1. Comparison table of optical plasma purification and traditional purification technology


2. Advantages of optical plasma purification technology:

Advanced technical principle:

All air purification products on the market are physical purification. The nature of the pollutants has not changed, but the pollutants are isolated from the indoor air and collected into the air purification system;

The optical plasma air purification system adopts a non-polluting compound chemical method to purify, and the nature of pollutants changes, and finally carbon dioxide and water are generated and blown back into the indoor air.

No secondary pollution:

The electrostatic air purification system mentioned in the previous comparison table uses a high-voltage electrostatic field to adsorb fine dust, and also ionizes nitrogen in the air to produce nitrogen oxides and compounds;

This by-product is a major component of car exhaust and a carcinogen. High-voltage discharge air purification systems also have this secondary pollution problem. But now the market propaganda only greatly enlarges his role and avoids its secondary pollution.

Active sterilization and purification, no dead ends:

Photocatalyst air purification, filter air purification and composite air purification are passive sterilization. Bacteria must enter the silo body of the photocatalyst air purification system and combine with certain substances in the silo body to achieve the sterilization effect. If the bacteria do not enter the silo body, there will be no sterilization effect;

The optical plasma air purification system adopts an active sterilization method, which can achieve the purpose of sterilization even if the bacteria do not enter the silo of the purification system.

No consumables, no bacterial virus retention:

The optical plasma air purification system does not require any consumables, which is economical and convenient;

The filter air purification system and composite air purification system on the market all need to replace the filter screen regularly, which not only has follow-up expenditure economically, but also when used for a long time, the filter screen will become a breeding ground for bacteria, fungi and viruses;

When the adsorption and filtration capacity of the filter material decreases with the use time, the collected pollutants may be blown out by wind pressure and re-diffuse into the air, resulting in secondary pollution.

High efficiency and fast speed:

The optical plasma air purification system has high sterilization efficiency and fast speed. It can kill bacteria and viruses in the air at any time, which is difficult for existing air purification products on the market.

Leading technology, high added value of products:

In view of the current serious product homogeneity in the air purification market, optical plasma technology has strong technical differences and innovation, and there are certain technological leading advantages and competition thresholds. It can bring higher added value to the final product.

4.  In- car air purification system    Business cooperation suggestion:

1. Competitive opportunities:

At present, most car manufacturers, including some foreign famous brand manufacturers, Do not pay enough attention to the problem of air purification in the purifier car. The current situation is also true target is also mainly aimed at the treatment of particulate matter, a harmful substance.

From our point of view, the air quality in the car is a systematic problem. The indoor environment and air quality control system should be listed as one of the major systems of the car. are closely related. The existing solutions on the market today are far from the goals of safety, comfort and health. Adding a purification widget is just to give a hype concept and selling point, and can't solve the problem in essence.

For different product series of automobile manufacturers, targeted system planning should be given. Form a standardized air purification system (automatic measurement and control unit) for different models.

2. Technical solution selection:

Semi-front loading scheme:

We define the air purification scheme of the armrest box as semi-front-mounted, because it is relatively independent from the structure of the whole vehicle, and there are relatively few comprehensive considerations involved in technology, and we have accumulated experience in similar products that we have actually cooperated with, which can be faster. Complete the design and mass production of mature products.

Front-loading scheme:

Combined with the air conditioning system of the car, with the optical plasma technology as the core, a variety of auxiliary purification technologies are used to fundamentally solve the various air pollution problems in the car. A standardized air purification system can be formed, which can effectively adapt to the design of a variety of different vehicle series. The purification efficiency and effect are much higher than those of the semi-front-mounted solution, and finally a relatively complete air quality purification system product is achieved. However, the automotive system links involved and the specific technical applications are more complex and may require a long R&D and testing process. However, in our previous technical exchanges with Great Wall and SAIC, we already have a certain basis of R&D accumulation, not starting from scratch without foundation.


To sum up, we can cooperate with the auto manufacturer's business plans and strategic choices, and gradually advance the product planning in stages, first easy and then difficult (for example, we can start with semi-pre-installation in the early stage, and gradually move forward with over-installation ) .

3.  Experience and suggestions:

Judging from the cooperation experience between us and BAIC bidding projects, from the perspective of product and project management, there are mainly the following two problems:

In the process of cooperation between the two companies, the intermediate technical coordination workload is huge, the communication cost is high, and the efficiency is low. After 10 months of technical research process.

In terms of business model, the partner is responsible for the overall design of the equipment, but does not understand the characteristics of the optical plasma technology. Although the final product meets the usable standard, it does not exert its maximum effect on the design level;

And because of the above reasons, the mold has been changed several times. Various experiences have shown that the design of the whole machine with optical plasma as the core technology is not something that can be easily grasped by technology manufacturers without relevant R&D experience.


In view of our years of R&D accumulation in the professional field of optical plasma technology, as well as a variety of comprehensive purification technology research and R&D and production experience of complete machine products, we design, develop and produce the final complete product to achieve the optimal allocation of resources. , Fang is an optimal business model choice.


We are willing to join hands with forward-looking automobile manufacturers to make joint efforts for the research and development of mature and perfect in-vehicle air purification system products, and to share the in-vehicle air purification market with great potential.
