Test experiments:
the large cabinet machine is arranged in a classroom room of middle and primary schools, concentration tests of ozone, carbon dioxide and PM2.5 are respectively carried out under the condition that 50 students are fully seated, the concentration of the ozone, the concentration of the carbon dioxide and the concentration of the PM2.5 in the classroom are tested every 5 minutes, and data are respectively recorded in a table 1, a table 2 and a table 3.
Table 1: ozone concentration test value
Table 2: carbon dioxide concentration test value
Table 3: PM2.5 concentration test value
According to the specification of T/CAQI27-2017 classroom air quality standard of primary and secondary schools, the first-class concentration limit value (1 hour mean value) of the indoor ozone is less than or equal to 0.10mg/m3The first-grade concentration limit value (1 hour mean value) of indoor carbon dioxide is less than or equal to 0.1 percent, and the first-grade concentration limit value (1 hour mean value) of indoor PM2.5 is less than or equal to 0.035mg/m3. From the average values of the three tables, it can be seen that the average values of the three items in the classroom room with the large cabinet are far smaller than the standard regulations, and the indoor purification is excellent.
While the invention has been shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the appended claims.
