Problems solved by technology
[0003] The former method is to analyze the air samples collected at a certain time point. The method of sampling and sending for laboratory analysis is accurate and authoritative, but it can only detect the time point of sampling, and the cost is high, requiring professional laboratory equipment and professional operation. Personnel, unable to give immediate feedback on test results, and unable to continuously monitor;
[0004] The latter method has a limited sensor life and requires frequent calibration and maintenance. The maintenance and replacement of the sensor is detrimental to management and cost.
[0005] Therefore, the above two methods are difficult to meet the detection and judgment needs of indoor air quality assurance in buildings.

Embodiment Construction
[0035] In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.
[0036] like figure 1 As shown, the use of indirect methods to estimate the concentration of pollutants in indoor air is based on the following principles:
[0037] 1) For bedrooms and living rooms in the home, or for rooms in public buildings for office and teaching purposes, the main pollutants that cause indoor air pollution are formaldehyde and VOC;
[0038] 2) Once the construction is completed, including decoration works and furniture arrangement, the total amount of formaldehyde and VOC pollutants has been basically fixed (except for a small amount and short-term brought in by other items), and this total amount Σ is the initial stage of pollutants. The total amount, which is equal to the cumulative amount of all subseque...

The invention provides an indirect realization method for detecting and judging the concentration of pollutants in the indoor air of a building, using the quantitative relationship between the total amount of pollutants that can be emitted, the amount of emission and ventilation intensity, and the total amount of pollutants after room interior decoration is used. It is fixed as the basic assumption. After the completion of the building, including the one-time pollutant detection data and its attenuation law after the completion of the decoration project, as the calculation basis, through continuous detection of indoor temperature, humidity, and carbon dioxide parameters, it is determined that after the completion of the building (including decoration) The total amount of pollutants is fixed, the release intensity changes regularly, the accumulation degree of pollutants in the room has a certain relationship with the degree of indoor and outdoor air circulation and a series of characteristics and quantitative relationships, and other parameters in the monitoring room are monitored. At the same time as the change, the indirect calculation of the concentration change of pollutants (formaldehyde, VOC) in the indoor air is realized.
Description
technical field [0001] The invention relates to an indirect realization method for detecting and judging the concentration of pollutants in indoor air of buildings Background technique [0002] In the prior art, there are two methods for detecting the concentration of pollutants in indoor air: one is sampling and sending for laboratory analysis, and the other is using a gas composition sensor. [0003] The former method is to analyze the air samples collected at a certain time point. The results of the method of sampling and sending for laboratory analysis are accurate and authoritative, but only the time point of sampling can be detected, and the cost is high, requiring professional laboratory equipment and professional operation. personnel, cannot immediately feedback the test results, and cannot continuously monitor; [0004] The latter method has a limited lifespan of the sensor and requires frequent calibration and maintenance, which is detrimental to the management an...
