Method for computing and grading indoor air quality index

Abstract

The invention discloses a method for computing and grading the indoor air quality index. The method comprises the steps of S1, selecting air quality parameters closely related to body health and comfort level to form indoor air quality parameters; S2, dividing the indoor air quality parameters into body health parameters and body comfort level parameters; S3, determining a method for computing the body health index and the numerical zone of graded pollutant concentration limiting values, and determining a method for distinguishing primary pollutants from standard exceeded pollutants; S4, determining a method for computing the body comfort level index and a graded numerical zone; S5, acquiring the indoor air quality parameters; S6, computing the body health index, and determining primary pollutants and standard exceeded pollutants; S7, computing the body comfort level index; S8, providing comprehensive assessment on the grade of air quality according to the body health index and body comfort level; S9, ending. By the adoption of the method, the normalization and accuracy of indoor air detection are improved.

Description

technical field [0001] The invention relates to the field of air quality detection, in particular to a method for calculating and grading indoor air quality indexes. Background technique [0002] The "GB3095-2012 Ambient Air Quality Standard" and "HJ633-2012 Ambient Air Quality Index (AQI) Technical Regulations" implemented on January 1, 2016 stipulated 10 ambient air (atmosphere) quality parameters, as shown in Table 1. Incomplete coincidence with indoor air quality parameters. And selected six major pollutants, sulfur dioxide, nitrogen dioxide, carbon monoxide, ozone, particulate matter (particle size less than or equal to 10 μm), and particulate matter (particle size less than or equal to 2.5 μm), to formulate the calculation and classification method of the ambient air quality index, However, it focuses on pollutant indicators, and has not formulated calculation and classification methods for human comfort. [0003] The human body's subjective perception of the externa...

Problems solved by technology

[0004] With the improvement of people's living standards and the development of science and technology, people hope to have a healthy and comfortable indoor environment for living and working, but the "GBT18883-2002 Indoor Air Quality Standard" implemented on March 1, 2003 only stipulates 19 kinds of Standard values ​​of indoor air quality parameters, which include standard values ​​of pollutant indicators and comfort indicators, but do not explain the calculation method and grading scheme of indoor air quality index
