time is particularly important as the core parameter affecting the test results. The
following is a description of the derivation process of the equivalent test time.
a) Under ideal conditions (regardless of factors such as concentration diffusion
uniformity and actual air exchange ratio, etc.), the purification efficiency of air
cleaner against the gaseous pollutants shall be determined by the number of air
cycles in the space of use. If the actually-running time is specified as 1h, then
obtain the Formula (A.1).
Where.
n – the number of air cycles, in times;
1 – 1 hour, in h;
Q –flow rate of air cleaner, in m3/h;
VA – use space of air cleaner, in m3.
b) When the initial concentration of gaseous pollutants in the actual use
environment of the air cleaner is the same as the initial concentration in the test
chamber during the test; obtain the purification efficiency of the gaseous
