The fresh air purification system is becoming more intelligent in 2020, or 50 billion in the market.

With the continuous enhancement of public health consciousness, the sales volume of fresh air purification system is growing rapidly in China. China's fresh air system market will reach 4.5 billion yuan in 2015 and 6 billion yuan in 2016, a 33% increase. It will continue to accelerate its development and reach 50 billion yuan in 2020.

In recent years, with the frequent occurrence of fog and haze, the serious situation of air pollution, an indoor air purification device - fresh air purification system quietly entered the Chinese market. However, compared with European and American countries, the market share in China is still very low.

"The low market share of fresh air purification system, the economic development level and environmental health awareness are also related to the lack of relevant regulations and standards in China, the design defects of traditional equipment and the inadequate service." Experts at the 4th Beijing Air Purification and Fresh Air System Exhibition said recently that the domestic market in this field should be considerable in the future. It is expected that the market will grow at an average annual rate of about 70% during the 13th Five-Year Plan period.

In 2020, the market space could reach 50 billion yuan.

It is suitable for installation in kindergartens, primary and middle schools, shopping malls, hotels, etc. the popularity rate in Europe and America is very high.

Fresh air "fresh air purification system will be outdoor fresh air after purification, filtration and heat exchange, transport into the indoor, while indoor dirty air discharged outdoors." Jiang Tianlu, CEO of a company in Beijing, said that the use of active replacement of indoor air, continuous filtering and purification of external air, indoor import, and accelerate indoor air flow.

At the exhibition, representatives of some manufacturers said that the fresh air purification system is particularly suitable for installation in kindergartens, primary and secondary schools, children's training institutions, hospitals, shopping malls, hotels, office buildings and family homes. If there are conditions, the air in the car should also be treated. European and American countries have used air fresh air purification system to manage indoor air for decades.

"In Europe and America, the popularity rate of fresh air purification system is very high. In China's buildings, the popularity rate of fresh air purification system is relatively low. According to Jiang Tianlu, only a few high-grade office buildings, shopping malls and star-rated hotels have installed the system.　　

The "China Fresh Air Industry Strategy Research Report (2015)" by Oveyun, a domestic market research organization, shows that with the increasing public health awareness, the sales of fresh air purification systems are growing rapidly in China. China's fresh air system market will reach 4.5 billion yuan in 2015 and 6 billion yuan in 2016, a 33% increase. It will continue to accelerate its development and reach 50 billion yuan in 2020.

Perfect standards to improve product quality

The new national standard defines four key indexes that affect the purification effect of air purifiers, and standardizes the air purification market in many details; the traditional equipment needs to be improved

Industry insiders say there are many reasons for the low market share of China's fresh air purification system. Among them, the laws, standards and products themselves need urgent attention. At present, these two obstacles are being gradually eliminated.

It is understood that the German DIN (Organization for Standardization) as early as the middle of the last century, DIN 1964 published the second part of the "fresh air and air conditioning: technical and health requirements" amendments. The ASHRAE (Building Technology Association) in 1989 formulated the "indoor air quality specification for fresh air".

At present, under the above regulations, the German residential fresh air purification system has become an integral part of the building. In the United States today, indoor installation of fresh air purification system becomes a necessity for life. It is reported that the annual sales volume of the fresh air purification system in the United States in 2005 has exceeded 21 million units.

However, the standard of air purifier was promulgated later in China. In 2002, the Air Purifier (GB/T18801-2002) was promulgated. After two revisions in 2008 and 2015, the Safety of Household and Similar Electrical Appliances (GB4706.1-2005) was promulgated in 2005. Previously, these standards only required safety certification of fresh air purifiers, but there was no relevant certification for the purification function, to a certain extent, restricting the development of the industry.

It is reported that in March this year, China began to implement the "air purifier" (GB/T18801-2015). "The new national standard defines four core indicators that affect the purifying effect of air purifiers, namely, CADR value (purified air output rate), CCM value (air cumulative purifying capacity), energy efficiency level and noise standards, and regulates the air purifying market in many details. Its implementation has obviously accelerated the whole industry's shuffling. " Participating experts said.

In addition, in terms of products, before the installation of traditional fresh air purification equipment generally need to lay pipes, need to be completed before the building decoration, so that a large number of old houses can not be installed, affecting the promotion of fresh air purification system.

At present, many manufacturers are embarking on product improvement, the development of straight-line equipment, only need to punch two holes in the wall can be installed and used. Another manufacturer has developed a soft fresh air pipeline with two zippers installed on the ceiling to firmly fix the pipeline, which can be installed in a flat shape and occupy less floor height.　　

Intelligent system is the trend of development.

Ensure accurate monitoring, provide a basis for air filtration and purification; according to real-time test results and set good operating parameters can be intelligent operation; parents can remote through the mobile phone to see the air quality of children's school conditions

"In order to occupy a larger market space, we should pay attention to the development of intelligent systems, which will be the development trend of the industry in the future." Jiang Tianlu said.

The traditional ventilation purifier is lack of effective monitoring means, inconvenient control, and lack of remote control, centralized control, intelligent control and other intelligent means. "Intelligent ventilation and purification system can meet the needs of consumers, more in line with the public use habits, in the market will be more competitive, is the future development trend in the field of air purification." Zhongguancun green building innovation technology alliance Secretary General Luo Bin said.

In order to realize the intellectualization of fresh air purification system, we must first ensure accurate monitoring. Air quality parameters such as PM2.5, temperature, humidity, CO2, TVOC (total volatile organic compounds) can be accurately monitored by air monitor to provide a basis for air filtration and purification, and the operation effect of fresh air purification system can be directly perceived. Jiang Tianlu believes that it is best to place an independent monitor in each enclosed space to accurately monitor the air in each room.

The core of system intelligence is intelligent operation. Through RS-485 industrial bus (a communication interface) or WiFi, the monitor intelligently interacts with the fresh air purification system. The operating parameters of the equipment (PM2.5, CO2, TVOC, temperature and humidity threshold) can be conveniently set through the LCD touch panel. According to the real-time test results and the set operating parameters, the fresh air purification equipment (such as wind valve switch, fan) can be easily set. Speed and whole machine switch can run intelligently. It can save energy and customize indoor air quality.

According to the introduction, the intelligent system of fresh air purification is also able to display indoor air quality intuitively. The results of air monitoring can be displayed intuitively by intelligent TV, large screen, PAD, mobile phone, etc. It can also view the air quality history curve, analyze the operation effect of the equipment, so that managers can timely grasp the air quality and equipment operation.

"For example, parents can also remotely learn about the air quality of their children's school classrooms through mobile phones. Therefore, intuitive display can enhance the satisfaction of employees, users and parents, and stimulate the enthusiasm of installation. Jiang Tianlu said.

In addition, the use of fresh air purification systems in shopping malls, hotels, schools and other large building facilities, especially the need to install a central control platform. The maintenance personnel can control the running state of the equipment in real time through the central control platform. By means of bullet window, short message, mail and other forms, the air quality is alarmed to exceed the standard, and the instructions for cleaning and material replacement are issued in time, so that the equipment can be maintained in time. The central control platform can facilitate batch control of multiple fresh air purification equipment.

Fresh air system should be vigilant for the two pollution.

The pipeline should be cleaned once a year.

When the temperature difference between indoor and outdoor is large, the fresh air system saves part of the energy for air conditioning to adjust the temperature of fresh air by heat exchange (making the air entering indoor outdoors closer to the indoor temperature), ensures that the introduced fresh air is clean by filtering system, and also avoids the outdoor noise pollution.　　

However, due to the lack of professional maintenance team, some fresh air purification system filters and pipes are still running dirty, easy to cause secondary pollution of indoor air. After the device is opened, the user may smell something peculiar.

Jiang Tianlu said that the system piping should be cleaned once a year. The filter screen of the filtration fresh air purification system should be replaced once every six months, the electrostatic fresh air purification system should clean the electrostatic precipitator once a month, and the filter screen should be replaced once a year or two (if any). "Heck Intelligent will train a professional certified maintenance team, using real-time monitoring and central equipment monitoring system, according to air quality on demand to replace consumables.

According to the introduction, the traditional purifier is in the airtight indoor, the pollutants in the air adsorption filtration, to achieve the purpose of indoor air cleanliness, there is no function of direct air exchange with outdoor air. Compared with fresh air purification system, simple indoor air purifier can not solve the problem of carbon dioxide exceeding the standard, and can not remove some complex components of indoor air pollutants.

Fresh air purifying system is to transport fresh air into the room after purifying, filtering and heat exchanging. At the same time, the indoor polluted air is discharged from the outside, and the indoor air is replaced actively to speed up the indoor air flow, and the fresh air is replaced directly without windows.
