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...
