Measurement and control method and device for particle concentration of indoor air

Abstract

The invention discloses a measurement and control method and device for the particle concentration of indoor air. The method includes the first step of setting up measurement environments, the second step of measuring data by means of a control variable method, the third step of managing the data, the fourth step of forming indoor air combination paths, and the fifth step of performing indoor air optimization. The device of the measurement and control method for the particle concentration of indoor air comprises an aerosol dust detector, a laser particle counter, a processor electrically connected with the aerosol dust detector and the laser particle counter, and air treatment response equipment electrically connected with the processor. According to the measurement and control method and device for the particle concentration of indoor air, for factors including indoor activity and indoor air and outdoor air exchange influencing indoor total suspended particles, which factors can influence the indoor air particle content are determined, and thus the indoor air particle content can be reduced in a targeted mode.

Description

technical field [0001] The invention relates to a method and device for measuring and controlling the concentration of air particles, in particular to a method and device for measuring and controlling the concentration of indoor air particles, belonging to the technical field of air quality detection and control. Background technique [0002] Air pollution is a global problem, and particulate matter is an important part of air pollution factors; in recent years, many researchers have conducted a lot of research on the sources of air particulate matter and mitigation measures, but their research directions generally focus on outdoor atmospheric monitoring Although the outdoor air pollution in many cities around the world is serious and has a great impact on people's outdoor activities, reducing or controlling air pollution is a direction with great research value, but the research on the indoor environment is also essential; studies have shown that people More than 70% of the...

[0002] Air pollution is a global problem, and particulate matter is an important part of air pollution factors; in recent years, many researchers have conducted a lot of research on the sources of air particulate matter and mitigation measures, but their research directions generally focus on outdoor atmospheric monitoring Although the outdoor air pollution in many cities around the world is serious and has a great impact on people's outdoor activities, reducing or controlling air pollution is a direction with great research value, but the research on the indoor environment is also essential; studies have shown that people More than 70% of the time is spent indoors. The quality of the indoor environment will directly affect people's physical and mental health. Therefore, it is necessary to study the pollution characteristics of indoor air particles; find out the concentration of indoor particles through experiments. What factors are affected, and use the data to propose methods to reduce indoor particulate matter pollution, thereby reducing the physical and mental harm of indoor particulate matter to people, and creating a healthy and comfortable living environment for people; in the prior art, there is no way to Research on the impact of indoor factors on the indoor environment, the impact of outdoor factors on the indoor environment, and the combined impact of outdoor and indoor factors on the indoor environment, therefore, it is difficult to provide targeted air quality improvement
