Abstract

The present invention provides a method and an apparatus for evaluating indoor odor intensity. The method comprises: separately calculating the odor activity values of each pollutant according to thechemical concentrations of each pollutant in a room; according to the odor activity values, screening the pollutants mainly affecting the odor as main odor pollutants; classifying the main odor pollutants according to odor types to obtain a variety of odor substances, and respectively calculating the total odor activity values of each odor substance; and based on the interaction relationship amongvarious odors in the room, establishing a conversion model between the total intensity of the indoor odor and the chemical concentrations of each odor substance, and calculating the total indoor odorintensity value according to the conversion model. According to the present invention, the total indoor odor intensity value obtained according to the detected chemical concentrations of the indoor pollutants can accurately predict the indoor odor intensity of the ordinary household so as to perfect the indoor air quality evaluation system.

Description

technical field [0001] The invention relates to the field of indoor air quality evaluation, and more particularly, to a method and device for evaluating indoor odor intensity. Background technique [0002] House decoration is the basic need of every family, and the pollutants emitted by decoration materials will seriously affect the indoor air quality. Paint, plywood, particle board, foam filler, interior wall paint, plastic veneer and other materials contain formaldehyde, benzene, toluene, Carcinogenic substances such as ethanol and chloroform, therefore, it is particularly important to evaluate indoor air quality. [0003] The current standard for evaluating indoor control quality (GB50325-2010) stipulates the chemical concentration requirements of pollutants emitted by decoration materials. However, in many cases, even if the chemical concentration of indoor pollutants does not exceed the standard, it does not mean that the indoor air quality is up to standard, because t...
