technical field

The invention relates to the field of indoor environment maintenance, in particular to a daily maintenance-free green window water supply and ventilation system and method.

Background technique

Indoor air pollution is divided into exogenous pollution and endogenous pollution. Exogenous pollutants refer to outdoor pollutants that enter the building through infiltration and ventilation to pollute the indoor air. Endogenous pollution includes formaldehyde, vinyl chloride, benzene and benzene compounds, radioactive substances released during the use of building structures and their surface decoration materials, furniture, fabrics, household appliances, etc., smoke and odors generated by indoor personnel activities, Dust mites, fungi, allergens, bacteria and viruses that are metabolized and grown by organisms. The excess deaths caused by indoor air pollution in my country can reach 111,000 people every year, and the annual loss caused by indoor air pollution in my country is about 10.6 billion US dollars. Indoor air pollution has become the second largest factor that endangers public health and the second largest "killer" that causes human lung cancer. It can be seen that the current air environment seriously threatens people's health and social development, not only causing additional economic losses, It also causes a lot of inconvenience to the society. In this context, it is extremely urgent to improve indoor air quality and prevent outdoor haze from polluting indoor air.

Through the collation of research contents in related fields at home and abroad, the current domestic outdoor air pollution is mainly from the source by adjusting the energy structure, strengthening legislation, law enforcement and policy guidance, establishing public awareness of environmental protection, changing behaviors, and strengthening ecological environment construction. Reduce pollutant emissions. At the micro level, the passive response to smog and the research on reducing the harm of smog to the human body are less involved.

In the face of indoor and outdoor air pollution, indoor air purifiers with different functions appear on the current market. These products mainly reduce indoor pollutants through purification technologies such as adsorption, nano-air filter materials, plasma, negative ions, and photocatalysis. However, these purification devices are expensive, require energy consumption, and require careful maintenance, frequent replacement of accessories, and may cause secondary pollution.
