Description

Technical Field

[0001] The present invention relates to the technical field of indoor air purification, and particularly to an indoor air purification system and method. Background Art

[0002] At present, with the accelerating process of population aging, the issue of elderly care has become the focus of the whole society. Creating a safe, comfortable and healthy living environment for the elderly is the key to improving their quality of life and ensuring their physical and mental health, and indoor air quality plays a crucial role in this.

[0003] Due to the decline of physical functions, the immune system of the elderly is relatively weak, and they often suffer from various chronic diseases such as asthma, chronic obstructive pulmonary disease, heart disease, etc. Relevant research shows that air pollution will exacerbate the symptoms of these chronic diseases and increase the risk of disease deterioration. Moreover, the elderly spend a long time at home every day, and the quality of indoor air has a more significant impact on them.

[0004] As an important elderly care place, the issue of indoor air quality in nursing homes cannot be ignored. In nursing homes, the sources of air pollutants are diverse, including the spread of bacteria and viruses generated by crowded people, and dust raised by daily activities. Poor indoor air quality will lead to an increase in the incidence of respiratory diseases among the elderly and an increase in the risk of infection, while also affecting their mental state and social interaction. Therefore, effectively controlling air pollutants in nursing homes and improving air quality are extremely important for ensuring the health and quality of life of the elderly.

[0005] Currently, for indoor air purification, common methods include ventilation equipment, air purifiers, etc. Ventilation equipment, such as fans and exhaust fans, promotes air flow and exchange with the help of mechanical power, can adjust the air volume, and maintain the freshness and circulation of indoor air. However, when the outdoor air quality is poor, such as in haze days, sandstorm weather, or there is serious industrial pollution, the ventilation equipment is difficult to function properly, and may even introduce more pollutants. Ordinary air purifiers can filter some particulate matter and adsorb some harmful gases. However, in the face of complex pollutants in the elderly care environment, the purification effect is limited and it is difficult to meet the high requirements of the elderly for air quality.
