People began to study and explore the impact of indoor air quality on human health, pollutants and their sources, and feasible solutions.
Method 1: Ventilation assumes that there is no pollution in the outdoor air, but in reality the outdoor air quality is not allowed.
Method 2: The air purifier is easy to saturate; the ultra-clean room: the same as the people drinking pure water, the microbes that are good for the health of the students are gone, and the building syndrome will be generated.
Way three: plant background wall
Can effectively reduce indoor dust (PM10, PM2.5
1. The surface of the plant is adsorbed by floating dust.
2. Through the absorption of pores in photosynthesis and transpiration.
The dust is sucked into the special water tank through the device in the plant wall, and the dust is forced into the water to continuously reduce the PM10 and PM2.5 stock in the room.
2. The transpiration of plants can regulate indoor humidity. The amount of water absorbed by plants through the roots is only used to maintain their own lives, and the rest is released into the air by transpiration. It has been verified that when plants account for 8% to 10% of the indoor area, the humidity can be increased by 20% to 30%.
3. Efficient removal of various harmful gases
The plant purifies the air mainly by its own photosynthesis and transpiration, and absorbs harmful gases such as formaldehyde, benzene, carbon dioxide and TVOC, and further decomposes and transforms through the body to form an available substance.
quality. At the same time, transpiration also releases anions, which combine with the air pollutants in a cationic state to neutralize each other.
4. Increase the microcirculation and oxygen content of indoor air
The circulation of air in the classroom can be achieved by a fan with a plant wall, and plants can produce oxygen through photosynthesis.
5. Aesthetics, protect students' vision, and occupy only a small amount of space.
