Environmental test chamber and method for obtaining testing environment by using same

Abstract

The invention provides an environmental test chamber and a method for obtaining testing environment by using same. The environmental test chamber comprises an inner chamber, an outer chamber and an air treatment system; the inner chamber is nested inside the outer chamber; the air treatment system is selectively connected with one of the inner chamber and the outer chamber; when the air treatmentsystem is selected to be connected with the inner chamber, an air inlet of the air treatment system is connected with an air outlet of the inner chamber, and an air outlet of the air treatment systemis connected with an air inlet of the inner chamber; when the air treatment system is selected to be connected with the outer chamber, the air inlet of the air treatment system is connected with the air outlet of the outer chamber, and the air outlet of the air treatment system is connected with the air inlet of the outer chamber; and the inner chamber comprises a pollution source generating device and a sampling port. The environmental test chamber can well imitate polluted indoor environment and can conduct purification property test on air purifying equipment under uniform test conditions,thus providing conditions for effectively evaluating the purification effects of the air purifying products on pollutants.

Description

technical field [0001] The invention relates to the field of environmental testing, in particular to an environmental testing cabin and a method for obtaining a testing environment by using the same. Background technique [0002] Due to the development of the economy and the improvement of living standards, people have higher and higher requirements for indoor beautification, and a large number of decoration materials are used indoors, resulting in more and more serious indoor air pollution problems. Therefore, scientists and the public are paying more and more attention to this issue. class questions. Subsequently, various air purification devices emerged as the times require, and more and more attention has been paid to them, which are commonly used equipment to improve indoor air quality. There are various forms of air purifiers on the market. According to the purification principle, they can be divided into physical adsorption filtration products, chemical decomposition...

AI Technical Summary

Problems solved by technology

[0003] In the process of realizing the present invention, the inventors found that the current research direction of the environmental test cabin mostly stays in the aspect of measuring the release law of organic matter in interior decoration materials and products, and there is no report on the research of the air purification device test cabin.

However, the various index parameters of the existing test cabins are not suitable for the performance test of air purification devices. They cannot simulate the polluted indoor environment well, and cannot provide uniform test conditions for different air purification devices, so that they cannot be effectively evaluated.
