When it comes to air quality, it is easy to focus on PM2.5, but in fact, excess carbon dioxide is also an invisible "killer" in the air. Many people may be surprised to learn that carbon dioxide is not toxic. How can it be an invisible killer of gases?
The "internal" problem of carbon dioxide in the air It all starts with carbon dioxide. As we all know, the atmospheric content of oxygen and carbon dioxide is relatively stable, with 21% of oxygen and 0.03% of carbon dioxide. Although carbon dioxide itself is not toxic, when the air contains more than the normal level of carbon dioxide, it will have an impact on human health.
So why is there a lack of oxygen when there is more carbon dioxide? Because when people breathe they absorb oxygen and exhale carbon dioxide. With more carbon dioxide, the amount of oxygen in the air is reduced accordingly, and people have become accustomed to the level of oxygen in their living environment. When the amount of oxygen absorbed is not sufficient, it naturally leads to discomfort and causes symptoms of oxygen deficiency such as a person not breathing well.
The concentration of carbon dioxide in the outdoor air is usually between 400 and 500 ppm, while the indoor air quality standards have shown that a comfortable and good indoor environment is better to keep the concentration of carbon dioxide below 600 ppm, which is almost the same as the outdoor carbon dioxide value. Therefore, the main way to crack the oxygen deficiency problem is to ventilate with the outdoors and introduce fresh air.
In the new air system, the very important component is the carbon dioxide sensor, the carbon dioxide sensor can real-time online monitoring of indoor carbon dioxide concentration, and according to the concentration value to adjust the new air system to open, and power air supply volume.
How is carbon dioxide concentration monitoring carried out?
A CO2 sensor is used to test the CO2 level in a target area. The CO2 sensor is used to verify that the CO2 level is within a range sufficient to ensure the safety of the occupants in the test area. the CO2 sensor is programmed to alert personnel if the CO2 level reaches an unsafe threshold.
In addition, carbon dioxide sensors can be used in greenhouses or grow rooms to ensure that the right level of carbon dioxide is maintained to produce healthy crops. Increased CO2 levels stimulate the photosynthesis process, resulting in stronger and faster growing plants, but CO2 levels must be closely monitored as too much CO2 can damage plants and pose health risks to employees.
