Comparison of the Methods of KACA and AHAM for Particle Cleaning Capacity Performance Test of an Indoor Air Cleaner
Abstract
Test methods of Korea Air Cleaning Association (KACA) and Association of Home ApplianceManufacturers (AHAM) for particle cleaning capacity performance of an indoor air cleaner were compared interms of the conditions of the test particle generation, the range of particle measurement and thecalculation methods for particle cleaning capacity, and types of the test particles. The performance test wasconducted in a 30 m3 chamber with the same test specimen and the test particles of each test weregenerated until the number concentration of 0.3 ㎛ particles reached 2.2 × 108 #/m3. The performance testresults showed that the cleaning capacity with the particles of higher surface area and volume density,regardless of the type of test particles, was higher than with those of lower and the capacity fromcalculation with 0.3～1 ㎛ particles was higher than with 0.3 ㎛ particles. Moreover, the cleaning capacitywith the calculation of KACA method was lower than with that of AHAM method in spite of using the sametest specimen.
