Coefficient of Mean Deviation of Indoor Pollutant Concentration and Indoor Air Quality Evaluation

When the distribution of indoor air pollutant concentration is asymmetrical, the mean concentration as position feature parameter couldn’t reflect the whole feature, there should be discrete feature parameter of pollutant concentration affecting the indoor air quality evaluation. Therefore, it is necessary to clarify the intrinsic relationship between subjective and objective evaluation, and to seek one evaluation method combining the subjective and objective evaluation. The influence of coefficient of mean deviation of indoor pollutant concentration to human subjective evaluation was demonstrated in this test. The main structural composition of this coefficient of mean deviation in those large areas, where the primary pollution source is carbon dioxide, was also analyzed. The existing problem of using an evaluation method that was objectively only by the average concentr
