Abstract
Removal effect of humidity-swing air cleaning method, where sample air is consecutively humidified with heating and dehumidified by cooling, on suspended particulate matter, SPM, is studied. And its possibility for utilizing low temperature heat source was discussed. The removal effect increased with increasing temperature and humidity difference between the humidification and dehumidification. 80% reduction of the total SPM was shown with the heating t0 66℃ and this condition demands a heat source of about 74℃. Thus, it is expected that this method can utilize low temperature difference such as waste heat.
