Does the fresh air system help with hazy weather?

The smog is mainly very tiny particles, which ordinary household fresh air systems do not seem to be able to filter.

If you are interested, please refer to the smog of China National Geographic No. 11, 2012**.

There are no air purifiers on the market that are particularly effective.

I also live in the city, such a big environmental pollution, we can only try our best to protect ourselves and our family, my family's practice can be referred to:

1. If you don't have to, go out less, and if you must go out, you must wear a mask.

Second, there is a treadmill at home, so that when the air is too poor, it will reduce the injury caused by going out to exercise.

3. My family bought a home oxygen concentrator, and the family inhaled oxygen for at least 20 minutes every day to ensure that my body was clean and oxygen-supplying.

Fourth, eat more food that is good for the body, traditional Chinese medicine believes that when the air is dirty, people are easy to get hot and hot, and cause gastrointestinal discomfort. At this time, the diet should be as light as possible, eat less spicy and greasy food, drink more water, and rest more to improve immunity.

Fifth, you can also plant some plants to purify the air at home, and the effect is also good. I don't believe in any air purifiers either.

I also live in the city, and we can only try our best to protect ourselves and our families from such a big environmental pollution. For example, don't go out to exercise in hazy weather. When you go out to exercise, you should also do a good job of protection.

Like me, I wear a mask of nine eagles. I have experienced the haze weather in Beijing in the past few days. There's nothing wrong with that.

Yes.

The fresh air system can effectively remove all kinds of bacteria and viruses in the room, and can also reduce the indoor carbon dioxide concentration. Of course, it can also be used to change the indoor air, so it is also very helpful for haze days.

The ducted fresh air system is composed of fresh air fans and pipe fittings, which purify the outdoor air through the fresh air fan and introduce it into the room, and discharge the indoor air through the pipeline, and the ductless fresh air system is composed of fresh air fans, which also purify the outdoor air by the fresh air fan and introduce it into the room, and at the same time discharge the indoor dirty air by the breathing treasure. Relatively speaking, the ducted fresh air system is more suitable for industrial or large-area office use due to the large amount of work, while the ductless fresh air system is more suitable for home use because of the easy installation.

Precautions for opening the fresh air system.

Replace the cleaning filter in time: The full heat exchange fresh air system is equipped with a filter screen and a full heat exchanger core that purifies the air efficiently, and these filter elements should also be replaced and cleaned in time. The filter screen of the fresh air system has a certain service life, and for the areas where the haze is more serious, such as Beijing, Hebei and Henan, the replacement cycle should be shortened, and it is recommended to replace it in 1 to 3 months.

Filters are washable and non-washable, washable filters can be operated according to the instructions for use, and non-washable filters such as HEPA filters need to be replaced regularly.

The above content refers to People's Daily Online-How to improve indoor air quality in haze days?

It is recommended not to turn on the purifier, because the fresh air system is to introduce the outside air into the room, if the external air quality is not as good as the indoor, then it will inevitably aggravate the indoor air pollution, and the fresh air is filtered in time, but its purification effect is still not as good as the air purifier.

It is impossible for the fresh air system to completely block the haze, and the auxiliary maintenance project is not done well, and it is easy to be polluted twice.

For the problems reported by the owners who have experienced the green technology system such as fresh air, Cheng Tongbao, Ph.D. of Tsinghua University and general manager of Century Tongbao Engineering Consultant, made it clear to reporters that the fresh air system can indeed play the role of ventilation and filtration, but this does not mean that the fresh air system can perfectly fight against haze. Everyone is responsible for protecting the environment, and the United States imports Guard, Xintian, and cats to effectively prevent haze.

Smog is harmful to people's respiratory and cardiovascular systems.

There are three reasons, first of all, haze is actually a large amount of particulate matter in the air, the most effective way is to filter, but the current market mainstream constant temperature, constant humidity, constant oxygen and other fresh air systems, are the best air conditioning, although it can filter the air, but it is difficult to achieve sub-high efficiency or efficient filtration, most of them are also conventional rough filters, and can not completely filter out the particles in the air.

In addition, the maintenance and maintenance of green technology systems such as fresh air is more important, and the filtered particles will adhere to the filter screen, and if they are not cleaned and replaced in time, these filtered dust will be blown back to the house with the fresh air.

Finally, the pollutants in the house itself cannot be removed by fresh air, such as formaldehyde, toluene, etc. Therefore, although the fresh air system can improve indoor air quality, the developer's promotion of dust-free and clean air is a bit exaggerated.

The fresh air haze removal system provides fresh air to the room, regulates humidity, removes formaldehyde, and can also fight against haze, and the effect is particularly good.

The indoor and outdoor ventilation and exhaust equipment of the fresh air system can deeply filter the air and introduce fresh air into the room, and the open air circulation system continuously provides fresh air 24 hours a day. The fresh air system can help you prevent respiratory diseases caused by air pollution, allergies caused by dust, pollen, mold, eliminate hidden dangers, and protect the respiratory health of your family.

The system can exhaust the dirty and humid air in the room, which can not only remove odors, but also prevent the growth of mildew and bacteria, and prolong the service life of buildings and homes.

Functional characteristics of the system

The multi-layer high-efficiency filter in the fresh air system can effectively intercept outdoor pollution particles and filter, so that you can enjoy the freshness of the natural oxygen bar while sitting at home, and the body consumes less energy, energy saving and environmental protection. The fresh air haze removal system is an independent air handling system composed of air supply system and exhaust air system, which is divided into two types: ducted fresh air system and ductless fresh air system.

The ducted fresh air system is composed of a fresh fan and pipe fittings, through which the outdoor air is purified and introduced into the room, and the indoor air is discharged through the pipe. The ductless fresh air system is composed of a fresh fan and a breather, which also purifies the outdoor air into the room by the fresh fan, and discharges the indoor dirty air by the breather.

As a home fresh air system that has entered the field of vision of the Chinese people because of the "smog killer", it is generally believed that the haze was "born", but studying its history, it is not difficult to find that this is not the case.

The fresh air system originated in Europe, as early as the 50s of the last century, there were low-noise and high-static pressure blowers suitable for various places. This kind of blower is the "prototype" of the home fresh air system. Due to the emphasis on energy conservation in the general environment at that time, a large number of buildings in the design and construction of a large number of buildings pay great attention to air tightness, in the heat insulation, heat preservation, sealing and other aspects of the improvement is significant, but also lead to a serious shortage of indoor ventilation rate, resulting in slightly weaker people often have headache, dry cough, dry itching, dizziness and nausea, difficulty concentrating and sensitivity to odor and other symptoms, known as "pathogenic building syndrome".

To solve the problem of indoor air pollution, opening windows for ventilation is a good way, but once the windows are opened, it will lead to the loss of indoor cold and heat energy, and at the same time destroy the overall insulation system of the building, and will also make outdoor dust and noise enter the room. Therefore, the contradiction of opening and closing the window has not been solved. It is for this reason that people are beginning to study and ** the impact of indoor air quality on human health, pollutants and their ** and feasible solutions.

The fresh air system can solve the comprehensive air problems of indoor particulate matter, formaldehyde, volatile organic compounds, bacteria, formaldehyde, carbon dioxide, oxygen and other comprehensive air problems through the exchange and purification of indoor air and outdoor air, and realize external circulation and internal circulation at the same time, so that the indoor air quality can be maintained at a level that meets the World Health Organization (WHO) human health breathing standards. It can be seen from this that the home fresh air system is not a haze-driven product, even if there is no haze impact, the home fresh air system will develop rapidly.

Schmebo fresh air system shares: the fresh air system is a kind of fresh air with sufficient oxygen content outside, after being purified by FECA technology, the clean fresh air is sent into the room, and at the same time, the indoor turbid air containing formaldehyde, benzene, ammonia and other toxic and harmful turbidity is discharged outside. Let the introduced fresh air and exhaust air exchange heat energy (heat exchange rate 78%), and through 24-hour uninterrupted circulation and replacement, so that the indoor air is always fresh, clean and oxygen-rich, and prevent air pollution from harming the body.

It can effectively filter and purify haze.

In recent years, smog has hit China one after another, and the outdoor air situation is worrying. So on the one hand, while calling for pollution control, we can only try to take protective measures - wear masks when going out, and close doors and windows indoors! The problem is that indoor air pollution is also a cause for concern.

There are many sources of indoor pollution: bacteria, dust mites, pollen, animal dander, dust, smoke, formaldehyde, plant spores, mold spores, chemical aerosols, and so on. As a result, indoor air pollution is worse than outdoor air pollution in a closed environment.

The main pollution of indoor space is:

1. Decoration pollution: formaldehyde, benzene, TVOC and other pollutants.

After the house renovation is completed, there will be various decoration pollutants in the interior. Its volatilization cycle is very long, and it is simply unable to improve the pollution left over from the decoration.

2. Carbon dioxide exceeds the standard.

If the doors and windows are closed and the indoor ventilation is not smooth, the carbon dioxide concentration will gradually rise, and the carbon dioxide concentration is too high to make people tired, dizzy, drowsy, memory decreased, and even affect the growth and development of adolescents. Especially after a night's sleep, a lot of carbon dioxide at this time is exceeded.

3. Cigarettes. According to CCTV, lighting a cigarette in a 15-square-meter room instantly rises from 32 micrograms to 1,100 micrograms of cubic meters, and even if the window is opened, it will take at least 16 hours to fully return to normal values.

Installing a set of fresh air system indoors not only prevents haze, but also accelerates indoor air circulation. Discharge all kinds of indoor air pollution in daily life and send fresh and clean air. Therefore, the fresh air system does not have to wait until the haze comes, but should be installed at the moment of occupancy.

For many users who have installed the Bruscher fresh air system, they have commented that this is the most correct decision they have ever made. After installing fresh air, I feel that the indoor dust is much less.

Usually when I go home from work, the moment I open the door, I feel a fresh air blowing in my face, and after installing the fresh air space, I adapt to such an environment, and I feel that the air is much worse when I go out.

Especially in the season of frequent haze, I feel a lot better when I see that the air index on the control panel has been in good condition.

If the external air quality is not as good as the indoor, then it will inevitably aggravate the indoor air pollution.

Air purifier.

It is passively purified, haze.

After entering the room, it is purified again, the purification rate is about 22%, and there are still many problems with the air purifier, the effective radius is 1 meter, and it will also produce ozone, noise, energy consumption, and cannot open the window, resulting in an increase in indoor carbon dioxide concentration, the formation of air pressure difference between indoor and outdoor, and the air is not circulating;

Fresh air system. Active purification, purification of haze through indoor and outdoor air replacement, haze blocking rate of about 25%, there are also some problems, cold and heat loss, pipeline bacteria brought into the room, noise, energy consumption, cleaning is more troublesome;

It is best to install a blue crown indoors.

Anti-haze screen, anti-haze, dust-blocking, environmental protection without energy consumption, breathable, insulation, active isolation of haze, haze blocking rate, user experience is also very good.

In the face of the haze days in the past few days, many consumers are particularly concerned about how to clean the air in their homes. Experts from Geruipu pointed out that in hazy weather, the most important thing is to prevent outdoor pollutants from entering the room. The fresh air system has the function of removing outdoor fine dust and keeping the indoor air fresh and clean for 24 hours.

If you want to deal with hazy weather, there are currently two fresh air systems that can be used. One is a fresh air system with heat exchange, heat ** and filtration. It can not only realize the heat exchange of outdoor and indoor air without heat loss, but also has some filter devices at the air inlet, which can generally filter out and above particles.

If the external air quality is not as good as the indoor, then it will inevitably aggravate the indoor air pollution.
