Study on indoor air quality evaluation index based on comfort evaluation experiment

Abstract

Based on the Weber/Fechner's law and PMV, the study puts forward the composition principle of indoor air quality evaluation index, and defines carbon dioxide sub-index PMV CO2, respirable suspended particulate sub-index PMV PM10, formaldehyde sub-index PMV HCHO, and indoor air quality index PMV IAQ. On the basis of indoor air quality comfort evaluation experiment and literatures, the rationality of these models is verified. Compared with the environmental parameters, the new defined comfort evaluation index models establish the link between the objective environment parameters and subjective comfort evaluation and unify the metrics of indoor environmental factors. If other environmental parameters are involved in the evaluation, the corresponding index can be built in the same way.
