Appraisal And Improvement Measure Of Indoor Air Quality

In recent years, the indoor environment has become one of many national attention environment questions. Air quality in the room weighs the important target in the indoor environment, already its research has became a new important constituent in the construction environment domain. Since the 70's, as a result of energy conservation request in the world scope, the building has strengthened airtight, correspondingly reducing the new amount of wind entered in the room ; On the other hand, the volatile organic compound gas massive sending out caused by the widespread application of organic synthesis material in the interior decoration and the equipment apparatus, seriously worsened in the room the air quality, which is called as "the morbid state construction syndrome" and had each kind of symptom. Many countries in the world, for example: US, Japan and so on, has studied the question of the air quality in the room comparatively early and obtained the certain achievement; In contrast the research in our country is just started, and the related air quality standard is in the blank. This article will study factors that affect the air quality in the room and the air quality appraisal method. This will provides the scientific basis for improving the indoor environment quality as well as the formulation of the indoor air quality specification.If people want to make sure that the air quality condition is or not suitable to the survival and the development, they must carry on the indoor air quality appraisal. Also because the indoor air quality involves the multi-disciplinary knowledge such as the building facilities engineering, the medicine, the environmental monitoring, the hygiene, the social psychology and so on. The indoor air quality appraisal is very complex. Presently, the indoor air quality appraisal generally employs the method which synthesizes the quantification monitor and the subjective investigation. Quantification monitor refers to the directly measure the pollutant density which comes to the objective understanding, and the subjective appraisal refers to using person's sense organ to carry on the description and the judgment work. The pure objective evaluation and the subjective appraisal all has its malpractice.
