Device for indirectly testing one-time purification efficiency of air purifying component and method thereof

Abstract

The invention relates to a device for indirectly testing the one-time purification efficiency of an air purifying component and a method thereof. On the basis of the prior art, the method comprises the following steps of: firstly closing a test passageway before testing by setting an adjusting passageway; adjusting the concentration and the humiture of a pollutant in a test cabin through the adjusting passageway to be a set value; and testing. The invention has the advantages that the invention controls the concentration of the pollutant which enters into the front end of a purifying component to be a constant value by adjusting a pollutant-generating device, thereby guaranteeing that the one-time purification efficiency is tested under the constant concentration of the blowing-in pollutant, preventing the computation of the one-time efficiency from having an error, leading a testing result to be more exact, and guaranteeing the purification efficiency and the accuracy of the test computation of the purification life.

Description

technical field [0001] The invention relates to the performance test of an air purification component, in particular to a method and a device for indirectly testing the primary purification efficiency of chemical pollutants and microbial pollutants of the air purification component. Background technique [0002] Indoor air quality greatly affects people's quality of life, health and work efficiency. Since people spend more than 85% of their time indoors, indoor air pollution triggers the following three diseases: Sick Building Syndrome (SBS), which is related to buildings disease (BRI), multiple chemical pollutant allergy (MCS). According to the statistics of the U.S. Environmental Protection Agency (EPA), the annual economic loss caused by poor indoor air quality in the United States is as high as 40 billion U.S. dollars. In my country alone, in 1995, the economic loss caused by indoor air pollution that endangers health is estimated to be as high as 10.6 billion U.S. dolla...

AI Technical Summary

Problems solved by technology

[0004] In the primary efficiency test of the purification component, in the direct test method of the primary efficiency, pollutants need to be released quantitatively and the concentration of pollutants in the pipeline should be stabilized within a certain period of time. The main problems in the whole test include: (1) contamination before the purification component The accuracy and stability of substance concentration control are difficult to achieve

[0006] The main disadvantage of this method is that the CADR calculation of the primary efficiency must assume that there is no relationship between the primary efficiency of the component and the concentration of pollutants. However, this assumption has been proved to be untenable by many scholars.

This leads to an error in the calculation of the primary efficiency, which leads to an inaccurate calculation of the primary efficiency
