'The development bottleneck of air purification'
When it comes to air purification, people think that the most natural thing is smog. Since 2013, when the national average smog days hit the highest record in recent years, smog has become a focus of attention in China's society. Under the same sky, it faces air pollution. No one can escape. The Chinese government is determined to control pollution. In the 'Ten State of the Air' promulgated, it proposes that the annual PM2.5 concentration in Beijing should be controlled at around 60μg/m3 before 2017. This goal has been basically Implementation. The environmental protection department announced that it would strive to reduce the annual average PM2.5 of all cities in the country to 35μg/m3 by 2030.
However, it is obvious that the governance of the air is not an overnight practice. With reference to the history of air governance in Europe and the United States for decades, this will be a long historical process. As a result, citizens have started to pay attention to the quality of indoor air. After all, people are in the The time in the interior takes up most of the time. It is because of the strong market demand and the obvious interest temptation that the air purification products for domestic use are becoming hotter and hotter. Many companies are also booming. More companies are involved in the air purification industry. It is a good thing, but it is a pity that some companies are too eager for quick gains and gains. They do not realize the seriousness of air pollution in China and its own characteristics. Many products do not meet the level of cleanliness they advocate, making this market a mixed bag of good and bad. The Shanghai Municipal Bureau of Quality Supervision announced the results of monitoring the quality and safety risks of air purifiers as an example. The measured values of its nine batches of samples did not reach its nominal applicable area. The Consumers Association of China released the "25 Purifier Products Comparison Test" The report also showed that only the particle purification efficiency is one, and the difference between the highest and the lowest is 5 times. And other providers of air purifiers not serious on this matter, not professional.
Air pollution in China’s North, East and South China regions is indeed very serious. This situation constitutes indoor air pollution with Chinese characteristics. Indoor air pollution not only results from the volatility of polluting gases not only from the interior decoration, but also from a large number of The outdoor pollution. This is different from the reason why people in Europe, America, Japan and other countries use air purifiers. Because of the strong air flow, when there is external pollution, it is difficult to keep the interior clean. If we close the room, With the traditional air purifier can also be purified, but because the most important role of human breathing is to breathe fresh air, people in the confined space activities will cause excessive carbon dioxide phenomenon. Since then, placed in front of the air purification industry is two to Solve the problem: Effectively purify and replenish fresh air. Simply relying on ordinary local circulation purification can not really solve the problem of indoor air quality.
'Fresh air purification research and development achievements'
In the face of this problem, in the past few years of practice development, a new concept has been put forward - the fresh air is purifying. The term 'new style' is no stranger to some people. Simply put, it means The outdoor air is introduced into the room after coarse and shallow filtration—the purpose is to ensure indoor air circulation and sufficient oxygen. However, if it is introduced under heavy air pollution, it will be counterproductive because the general fresh air system cannot filter PM2. 5, and high cost, not suitable for general income households to buy. If there is a general fresh air system can be added to high-grade filter materials, the air filter before the introduction of new air, and the miniaturization of the new air system, then the problem will be solved.
GRARR launches 'School Clean Air Action' Launch Ceremony at National Convention Center
Why is GRAIR's new style ultra purification product different?'
Ben Wang editor: You said that at the beginning of the company's original heart is to find the ideal purifier failed, why the traditional purifier or even foreign 10,000 purifier can not fully block the haze? What are the differences between the new style of ultra-purified products?
Liu Chunxing (hereinafter referred to as 'Liu'): This needs to start with the design and performance of the air purifier itself. The traditional air purifiers have three deadly weaknesses.
First of all, if the purifier is used in a confined environment, the biggest problem is that the concentration of carbon dioxide will exceed the standard. In foreign countries, the building itself is equipped with a fresh air system. By replacing the outdoor clean air, it plays a role in basic purification. The purifier is only used as an auxiliary purification equipment and will not bring about the above problems. However, the domestic situation is that most of our buildings do not have a fresh air system.
Secondly, there are gaps in the building doors and windows, and they cannot be closed tightly. The haze and day purifier cannot block the dirty air outside the room from permeating into the room through the gaps in the doors and windows, and cannot cut off the pollution sources. The purification will not be thorough.
Third, traditional purifiers are academically called 'self-cleaners' and can only partially purify the surrounding air. The purifying effect on other parts of the house away from the purifier will decay significantly.
For the above drawbacks of the purifier, we propose our own solution.
First of all, we are neither ordinary purifiers nor ordinary new fans. Instead, we combine fresh air and purifiers. This solves the problem of air cleanliness and freshness at the same time, that is, we need to remove PM2.5. Have fresh air.
Secondly, for the problem that we cannot cut off pollution sources, we use internal and external pressure differentials to solve. To give a simple example, when a balloon is blown, if a hole is made in the balloon, it must be the air inside, the outside air Can't get in. Our machine principle is the same. Through the difference in indoor and outdoor air pressure, the dirty air outside cannot penetrate through the windows and doors, cutting off the pollution source.
Thirdly, in response to the problem of local self-recycling of traditional purifiers, we solved the problem of overall circulation by using a cross-wind return system across the room. Traditional purifiers are not ideal because they do not circulate indoor air and are always repeatedly purified. There is local air around the device, and this part of the air is just the cleanest in the room, and most of the air does not need to be purified, so it is always doing no use. And the technical principle we designed was to pump the dirtiest air in the room to purify it.
Where is the room where the air is the dirtiest? The farther away from the purifier, the dirtier the air. How can we get the dirty air back? Our purifying opportunity is installed in the corner of a room, and a return air outlet is connected to the next room, from the next room In the corner, the indoor air is circulated and purified. From the path, we are always purifying the farthest and the dirtiest air. It also drives the flow of the entire indoor air and realizes the air purification of the indoor full space. So in the same way In the case of air volume, the efficiency of one purifier is 3~4 times that of other purifiers.
To sum up, we focused on the core issues of the purifiers, and proposed a comprehensive solution for the air purification of the entire interior space in response to the building conditions in China, the polluted climatic conditions, and combined the advantages of the fresh air system and the purifier into one. The air flow is circulated to work. Therefore, it can be done in an effective way. First, the indoor does not cause the carbon dioxide concentration to exceed the standard; second, the outdoor pollution to the interior is effectively blocked; and third, the indoor air can circulate quickly. Purification. With the above three points, coupled with our use of H14 filter HEPA filter for safe physical filtration, a PM2.5 removal rate of up to 99.9995%, for a more subtle level of PM0.3 (large Most of the bacteria and viruses belonging to this particle size have a primary cleaning removal rate of 99.7% or more. Our machines are actually operating to allow the room to quickly reach 35 (micrograms per cubic meter) or less, and continue to maintain , It will not cause the carbon dioxide concentration to exceed the standard, so that users want to scream the effect. Now most manufacturers do not dare to promise the purification effect of the entire space. However, we dare, we will randomly send a third-party watch, users can freely measure the PM2.5 value of any place in the house, let the data speak, and let the customer rest assured.
'Grundig loves the new super clean machine afraid of imitation?'
This site edits: The system design of Grune's new air ultra purification product is more scientific, but competitors are also very easy to imitate. How to solve this problem?
Liu: Grundig is engaged in the research and development of professional-grade medical grade purification systems. The design and construction has been more than 15 years old. It has obtained a number of invention patents and utility model patents in the field of fresh air purification. The technology on the civilian fresh air purifier includes both the indoor airflow circulation organization technology and the product purification technology. In addition to scientifically designing the airflow organization, many problems will arise if the core technology is not mastered during the productization process. , There are still quite technical thresholds.
What is the real difficulty of the purifier? First, the machine needs a large amount of air output. When the air volume is large, the pressure of the wind is not large. Both flow and pressure are contradictory. When the air volume is large, the pressure is very high. When large, it requires a high capacity of the fan, then the noise will be very large, and the fan's energy consumption will be very large. So the four indicators of wind pressure, air volume, wind noise, energy consumption are contradictory body. End, can really solve the relationship between the four can be said to be a good product. This is why the general purifier does not use high-grade HEPA filter, although the H14 filter can not only purify PM2.5, and PM0. The removal rate of 3 is also as high as 99.7%, but the above four major contradictions have been deterred from general purifiers. Our products have solved these contradictions very well. We have consistently applied H14 grade filter cartridges to ensure the purification efficiency of pharmaceutical grades. Energy consumption and noise are not high. In this regard, not only the core patents, but also our technology Knowhow for more than a decade, so we are not worried about other companies to imitate.
'The ultimate product of air purification: Achieves a customized air-conditioned system
This site edits: Which is the civil product that can represent the level of technology in the grid?
Liu: It should be said that we can achieve the air customization of the Grundig Central Greening System. Grunley has achieved great breakthroughs in the civilian use of P3 laboratory technology. According to the technical requirements of P3 Laboratory, we have successfully In our villa-level central afforestation system products, we have achieved effective regulation and control of the air temperature, humidity, cleanliness, freshness, airflow organization, and air flow uniformity throughout the villa, creating a successful China-based reality. In the six-dimensional space, Grundy Central's central greening system products have adopted a combination of technologies such as fresh air purification, remote air return, filtration and sterilization, temperature control and humidity control, and sterilization, so they can use intelligent centralized control systems for customers. Create a high-end custom air environment with constant temperature, constant humidity, constant oxygen, constant cleanliness, and constant high temperature. Our new air purification systems or stand-alone systems for general public spaces and home environments also strictly follow the above harmless purification, fresh air purification, and positive pressure. The basic principle of purification, efficient purification, to create a satisfactory purification effect for the customer.
'What is the difference between Grundig's new wind super clean machine and the general fresh air system?'
Bennet Editor: What is the difference between the company's system and the market's brand new air system?
Liu: First of all, from the principle of technology, we are different from other manufacturers. The general fresh air system still uses ventilation and ventilation as the main target of appeal. It is a new trend. We are a comprehensive product that supplements the fresh air plus comprehensive purification, fresh air system and purifier. The two are not simply tied together to solve the problem.
The common new air blowers on the market today mainly solve the problem of pollution caused by excessive oxygen and carbon dioxide concentrations through indoor and outdoor air exchange. However, in the Chinese environment, fresh air is sent in dirty air, so many have installed new air blowers. The customers are particularly tangled in pain, and the haze and the new wind are still open or open. The opening is to send dirty air to the house.
In order to solve this problem, many new wind manufacturers have added a purification section to clean the air at the new outlet. However, in order to avoid the four major contradictions: wind pressure, wind volume, wind noise, and energy consumption, they use low-level HEPA for purification. The result is that The rate of one-time decontamination is low, and a large amount of dirty air is still being sent into the room. Other new-blower manufacturers are looking for other purification technology routes, such as electrostatic precipitator technology, ion technology, adsorption technology, and water washing technology. Dust removal is carried out by the positive plate by charging the dust in the air through an ultra-high voltage electrostatic field. The advantage of this technology is that the wind resistance will be relatively small, and basically no consumables, so many new wind manufacturers use. But this technology is easy to produce ozone, and Nearly 10,000 volts of high-voltage electrostatic fields have inherent safety hazards. Not only do they ionize all kinds of impurity ions, but they also cause discharges due to large particles and fibers. Power cuts and broken wires can also blow off dust and stop working because after that No shadowing, seriousness can be imagined, so this technology has uncontrollable risks. After a period of use, it will lead to a sharp drop in purification efficiency. , Maintenance is extremely difficult. Electrostatic purification technology is not recommended for civil use in Europe and the United States, the American Society of Heating, Refrigerating and Air Conditioning (ASHARAE), German hospital standards have inscriptions in the intent of the document. Ion purification technology is to release charged ions into the air, micro When the dust belt is powered on, it will absorb dust, and the small particles will turn into large particles, which will slowly settle. The particles will not be purified. They will only settle out of the space and a dust will fly again. This type of ion technology also has a very strong wind resistance. Small, but the side effects are unknown, especially a large number of positive ions, which have potential harm to the human body. In short, the premise of choosing purification technology is that there are no side effects, no hidden safety technology.
Secondly, the vast majority of current new-style products are engineering-grade products that need to be laid, so they can only be installed at the time of renovation. This is unrealistic for most families who have already renovated their homes. Our products are another one. The great advantage is that through simple installation, you can solve the problem of fresh air without laying pipes.
The third difference is that the other fresh air systems only input fresh air, there is no indoor circulation purification function, and our machines can purify the indoor air to purify it, and have achieved clean air in any corner of the room, not just the air outlet. The air is cleaner.
How is the cost-effectiveness of the use of GRAR's new super-purifier?'
This site editor: For the purifier, in addition to the technical principles you just mentioned, the price of consumables such as filter elements has become an important indicator for consumers to choose a purifier. How is our product cost-effective?
Liu: First of all, the filter cartridge we use is a medical-grade H14 filter cartridge that can effectively purify PM0.3 ultra-fine particles and viruses. Even if SARS occurs again, users can sit back and relax. In addition, our filter cartridges are targeted at China's pollution situation. The dust content of the reverse design is based on Beijing's average daily PM2.5 value of 120 micrograms/cubic meter to calculate how much filter capacity is needed. Therefore, we can change the filter element once a year.
Therefore, in general, the filter element equivalent to the unit area unit, our filter core cost is still relatively high.
In addition, our fresh air purifier has a much higher purification efficiency than conventional purifiers, as well as a higher energy-saving design. Therefore, the energy consumption per unit area is much lower than that of ordinary purifiers.
