Nowadays, in developed countries, fresh air system has become a necessary equipment for new buildings. In 2009, the healthy fresh air system became one of the ten necessary technologies for future housing in China International Housing Expo-"Tomorrow's House". Shengdao fresh air system is not only a necessity for luxury villas, but also an indispensable equipment for ordinary people's lives. For the sake of people's health, China Generation Nanjing Shengdao Environmental Technology Co., Ltd. of Shengdao Fresh Air System called on Xinfeng Company to provide high-quality fresh air system installation services for the people.
Central fresh air system is one of the necessities of future life, and it is an indoor ventilation device based on negative pressure principle, which is very important to people's health. Shengdao fresh air system has experienced ten years of wind and rain in China, and has changed from a symbol of high quality to a necessary equipment for home life. In the near future, the island family self-balancing fresh air system will enter thousands of households.
Look at the following reports of health damage caused by decoration:
Bloody facts! ! !
Every year, 2,654.38 million children die from decoration pollution.
-Among them, more than 1 10,000 children under five died of indoor air pollution. Nanjing Morning Post, August 2003.
The whole family caught a cold about the house decoration.
-Formaldehyde exceeds the standard? The construction company compensated 1 10000 Jiangnan Times in February 2003.
Everyone needs 30m3/h fresh air 《 Indoor Air Quality Standard 》 March 2003
Leukemia and indoor air pollution. August 2007
Environmental protection materials+environmental protection furniture ≠ Indoor air environmental protection Sina. September 2007
68% of diseases are caused by indoor air pollution.
How to solve the decoration pollution?
Experts from CDC and several large hospitals said: Indoor air pollution! ! ! Is the culprit. And poor ventilation leads to indoor air pollution! ! ! To improve indoor air quality, we must ventilate! ! !
How to ventilate? Open the window? Or use ventilation equipment?
Owner: My apartment is good, and the north and south are transparent. Open the window.
It is conceivable that opening the window will lead to airflow disorder, which may bring the odor of the bathroom and kitchen into the living room and bedroom; The toilet shaft may produce the phenomenon of odor "backward flow"; Outdoor air carries a lot of outdoor dust, which affects indoor cleaning; There are inevitable irritating noises; Heating will cause a lot of waste of energy and electricity. In view of the above reasons, window ventilation will greatly reduce your quality of life.
Owner: There was no fresh air system before, so people didn't live well?
Dear friends, we used to live in wooden windows, and the walls were made of mud and stone. These are gaps that can be ventilated! Take a deep breath. Airflow can flow indoors and outdoors through tiny gaps, and it will also bring harmful gases and smoke out of the room when passing through the house. This is the "breathing" of the house-natural ventilation.
However, sealed windows and external wall insulation technology make the house look like a highly closed container. Outdoor fresh air can't enter the room, and indoor smoke, humidity and smell are blocked in the house, just like a "gas tank". Can people live comfortably in such a "house"? ! Dare to breathe? ! Can clothes and food be put in it without mildew and deterioration? ! Not only uncomfortable, but even life-threatening in severe cases! ! ! In recent years, various diseases and deaths caused by excessive indoor air pollution caused by home decoration are increasing day by day.
Family decoration, necessary fresh air system! ! !
Owner: I can control indoor air pollution in other ways, such as in addition to formaldehyde.
Dai Liquan, deputy director of the Market Working Committee of China Health Care Association, said that at present, many products claiming to prevent decoration pollution and remove formaldehyde in the domestic market are mostly coated on the surfaces of large core boards and furniture to temporarily hide harmful substances such as formaldehyde. In fact, this substance is only a "surface sealing agent" rather than a "decomposition agent", which can only temporarily wrap formaldehyde in release sources such as plates. Once there is a problem with this coating, harmful substances such as formaldehyde will be released again and become a hidden "time bomb" in the family. "The embankment of a thousand miles, collapsed in the ant nest".
Environmental protection materials+environmental protection furniture ≠ environmental protection decoration? More indoor environmental safety
Owner: I can use green materials.
According to the air test of newly decorated rooms by national authoritative organizations, more than 95% of the rooms have formaldehyde content exceeding the standard, and the most serious one is more than 60 times. None of the total organic volatiles (including benzene, xylene and formaldehyde) is qualified. At present, more than 80% of green environmental protection materials on the market are unqualified; All kinds of "green" building materials are used in closed rooms. Because of "superimposed pollution", the harmful substances they emit far exceed the national emission standards, which makes the indoor pollution area far more than the outdoor pollution area.
For technical reasons, the control of indoor air pollution has become a chicken rib. Therefore, it is necessary to have an indoor fresh air system. Through constant indoor and outdoor air exchange, the harmful gas generated is discharged outdoors, so that the indoor harmful gas concentration is far below the level that can harm human health.
Owner: It's useless. It's just an exhaust fan
Ventilation fans can't continuously eliminate indoor odor and can't meet the replacement demand of indoor fresh air; It is easy to be damaged, and the later maintenance cost increases; Can't keep ventilation; Loud noise; When no fresh air is introduced, the exhaust resistance increases and the effect is not good. Even without the above shortcomings, considering the small air volume and limited range of exhaust fans, it is impossible for you to install an exhaust fan in every room, and even if it is installed, it will not achieve the effect. Who uses a carriage when there is a car? !
At present, 80% people in China don't know the fresh air system, and more than 90% people don't understand what the fresh air system is for. In the case that the country advocates fresh air system and many developers are using it, 80% decoration companies think that fresh air system has no development prospect and is useless! Considering the decoration cost, it is also one of the reasons why the decoration company is not interested in the fresh air system. What others say is always one-sided. It's time for us to make our own judgment. Most countries in Europe and America have forced the installation of fresh air systems, not because of beauty, but because of the health of people in "houses" (if they can still be called "houses"). We have to admit that Europeans and Americans are ahead of us in paying attention to health.
SARS, avian flu, swine flu ... have brought us shock and fear, but you may have overlooked the following symptoms, which are all concrete manifestations of poor indoor ventilation on human health:
Every morning, I feel depressed, nauseous and even dizzy. My family often catches a cold.
Although I don't smoke, I often feel sore throat, foreign body sensation and poor breathing.
Children at home don't want to stay at home, often cough and sneeze, and their immunity drops.
Family members often have skin allergies and other problems, and they are produced in batches.
There is something wrong with the family. After leaving this environment, the usual symptoms have obviously changed and improved.
The newlyweds have been infertile for a long time, and they can't find out the reason.
Normal pregnancy of pregnant women found fetal malformation.
In a newly moved or renovated house, indoor plants are not easy to survive, and leaves are easy to yellow and wither.
Domestic pet cats, dogs and even fish died inexplicably after new tricks.
Newly renovated homes and offices or newly bought furniture have pungent, dazzling and pungent smells, and this smell will linger for more than a year, but you may have suffered a lot this year.
If the above symptoms appear, you just remember this post that you saw somewhere on the Internet at a certain moment. I'm afraid your health has been greatly threatened! At that time, it may not be a problem that can be solved by thousands of dollars. What you may pay is health and happiness, especially newlyweds and babies, which can not be ignored! ! !

Comparison between Shengdao Fresh Air System and Other Ventilation Modes
Opening a window: opening a window will lead to airflow disorder, which may bring the odor of the bathroom and kitchen into the living room and bedroom; The toilet shaft may produce the phenomenon of odor "backward flow"; Outdoor air carries a lot of outdoor dust, which affects indoor cleaning; There are inevitable irritating noises; Heating will cause a lot of waste of energy and electricity. In view of the above reasons, window ventilation will greatly reduce your quality of life.
B exhaust fan: the exhaust fan can not continuously eliminate the indoor odor and can not meet the replacement demand of indoor fresh air; It is easy to be damaged, and the later maintenance cost increases; Can't keep ventilation; Loud noise; When no fresh air is introduced, the exhaust resistance increases and the effect is not good. Even without the above shortcomings, considering the small air volume and limited range of exhaust fans, it is impossible for you to install an exhaust fan in every room, and even if it is installed, it will not achieve the effect. Who uses a carriage when there is a car? !
C air conditioner with some fresh air: the air received by the wall-mounted air conditioner comes from the air conditioner itself, and a closed circulation system is formed between the room and the air conditioner; Some central air conditioners with fresh air are difficult to continue to supply air because the fresh air forms positive pressure in the indoor area; Bacteria multiply in the air outlet, especially in winter, and the temperature of the air conditioning port is a hotbed of bacteria; The purpose of full exchange of indoor and outdoor air cannot be achieved, and the price is higher than that of ordinary air conditioners.
D ordinary duct air supply: it is difficult to control the air volume of each tuyere, and it is impossible to change the air supply according to individual needs; Dirty air cannot be discharged quickly, which will cause pollution; There is no ventilation path, and the airflow organization is not good; Without exhaust, it is difficult to send fresh air in the positive pressure area; Loud noise; Short life, can not meet the requirements of continuous ventilation. Compared with the fresh air system, it is the difference between guerrillas and regular troops.
E air purifier: it can only absorb dust and other particles in the air, but can't eliminate harmful molecules. Even after repeated treatment, the effect is still very poor.
F air disinfectants and air fresheners: after being sprayed indoors, they are mixed with the original dirty air, which is equivalent to painting a "disguise" indoors, paralyzing people's noses and having the taste of "hiding ears". Indoor air pollution is not only incurable, but also secondary pollution, making indoor air worse. Freon is also the destroyer of the atmospheric ozone layer.
G negative ion generator: during operation, negative ions are easily neutralized by opposite charges. Even negative ions that are not neutralized only have disinfection and sterilization effects, but have no scavenging effect on harmful gas molecules such as formaldehyde.
