In the past ten years or so, the requirements and standards for indoor air quality at home and abroad have been continuously improved. Correspondingly, a series of standards and specifications have also been proposed. Especially in recent years, China has formulated and updated relevant standards for indoor heating and ventilation systems and indoor air quality.
China's relevant requirements for indoor air quality stipulate that the indoor CO2 concentration is always required to be less than 1000ppm, and the CO2 concentration in the atmosphere is usually maintained at about 400ppm. The concentration of carbon dioxide is not only a factor that directly affects indoor air quality, but also directly reflects the number of people and activities in the air-conditioned environment.
The importance of keeping the CO2 concentration low is not only that it directly affects the working conditions of people in the environment, but also helps to improve people's work efficiency. At the same time, this means that there is enough fresh air in the current environment, which greatly reduces the risk of building syndrome. The CO2 concentration index can also reflect the approximate status of other harmful gases in the current environment to a certain extent. Therefore, CO2 sensors play an important role in the control of heating and ventilation systems. Using a carbon dioxide sensor, the amount of fresh air can be truly controlled according to needs, complying with green building codes, and achieving energy saving.
Therefore, the monitoring of air quality cannot be separated from the application of high-precision CO2 sensors. In addition, the energy-saving realization of heating and ventilation systems is also inseparable from the application of CO2 sensors. The heating and ventilation system can monitor the CO2 concentration value in the room in real time through the CO2 sensor, and bring in fresh air from the outdoors in time according to the current CO2 concentration, without having to keep the fresh air all the time, thus avoiding unnecessary energy consumption.
The use of the air conditioning system usually takes more than 10 years. During this period, all components of the system must be stable and reliable, including the important CO2 sensor. Gongcai.com is the agent of a variety of carbon dioxide sensors, such as the British GSS low-power HVAC dedicated infrared carbon dioxide sensor (NDIR CO2 sensor)-COZIR-A, based on IR LED patented technology and innovative light path design, and optional temperature and humidity output.
