Description
Technical field
Technical field of measuring equipment is the utility model is related to, more particularly to a kind of novel air pollution mean concentration measurement
Instrument.
Background technology
So far, all air quality detectors are all measurements, show the concentration of instant air pollutants.Than
Such as, the PM2.5 concentration that certain air quality detector is measured in air has reached 500 μ g/m3, the data are for relevant air matter
Any problem can not be illustrated for the standard and health effect of amount.It is related to health effect for relevant air quality standard
PM2.5 concentration is that 24 hour average concentrations are 25 μ g/m3, mean annual concentration is 10 μ g/m3.Again for example, certain air quality detector
The gas concentration lwevel measured in air has reached 2000ppm, the data for relevant criterion and health effect not
Any problem can be illustrated.It is that 8 hourly averages are dense for the relevant air quality standard gas concentration lwevel related to health effect
Spend for 1000ppm.It is not only relevant with the concentration of pollutant with health effect for the relevant criterion of air pollutants, and and people
Exposure time it is relevant.
For PM2.5, the World Health Organization provides that its standard is that 24 hourly average values are 25 μ g/m3, annual mean is
10μg/m3.For atmospheric environment, the present whole world only has a few countries to reach with area.But when, indoors, China is
Through interference method can be taken to reach this standard.The PM2.5 pollutions that existing air quality detector detects in display
During thing concentration, the per day 75 μ g/m in China's transition period3, the μ g/m of annual 353It has been set to outstanding air quality standard,
Also air pollution index API is set to outstanding air quality by some for 50.This display air pollutant concentration is excellent with polluting
Method be wrong.China's pollutant standard is not suitable for indoor air pollutants concentration, and China does not have also so far
Provide the PM2.5 concentration standards in room air；Standard about PM2.5 refers to mean concentration, rather than the inspection of existing air
Survey the instant concentration value that instrument detects, and such as carbon dioxide, 24 hours interiors of China's IAQ correlation standard
The carbon dioxide concentration in air limit value is 1000ppm, and correlation standard is 700ppm in the world.Correlation standard is 24
The instant concentration value that hourly average value rather than existing air detection instrument detect.
The defects of existing air quality tester is all can not measure, handle with showing being averaged for air pollutants
Concentration and open-assembly time, so as to which whether the air pollutants that are beyond expression reach related air quality standard, can not also represent with
The health effect of people has any relation.
