Multifunctional air purifying disinfection device performance detection system

Abstract

The invention relates to a performance detecting system of a multifunctional air cleaning and sterilizing unit, and the performance detecting system comprises an air tunnel structure, a data collecting and controlling system, and an aerosol generating and collecting system, wherein, the air tunnel structure comprises an air tunnel, an air intake and an air exit of the air tunnel are separately arranged with an electric air seal valve, and the air exit of the air tunnel is connected with an air extractor. The invention can meet the performance detection of the air cleaning and sterilizing unitin large span air output range and with different sizes; and can measure varieties of performance indexes such as the resistance of the air cleaning and sterilizing unit, the size and concentration counting efficiency and weight-calculating efficiency of air dust and artificial dust, the microbe elimination efficiency of atmosphere fungus and artificial fungus, and the gaseous pollutant elimination efficiency of formaldehyde and toluene. In addition, the invention can double as the performance detecting system of both a normal ventilation air filter and a high efficiency air filter.
