摘要

By using total volatile organic compounds( TVOC) as the objective volatile pollutant,the purification efficiency of some representative air purifiers bought in the market was determined under the relatively independent and stable environmental conditions supplied by the self-made multifunctional environmental test chamber. Various evaluation parameters of TVOC were calculated based on the tested results,such as purification efficiency and removal rate. The results showed that the TVOC purification efficiency increased with enhancing the temperature or lessening the relative humidity,but this effect is not obvious. The air purifiers which use photocatalytic technology have higher TVOC purification efficiency than those which only use some adsorption technology. The purification efficiency and removal rate can be more accurate to evaluate the purification efficiency of air purifiers.
