In this paper the measurement results of deodrant experiments using one-fluid sparay nozzle and weakly acid hypochlorous acid solution as a deodrant material will be reported and the damping behavior of the odor naterial will be clarified.
The microbial contamination in the ventilation system and the indoor air quality were evaluated in the underground shopping mall, Sapporo. The energy consumption of the shopping mall was investigated for five years from 2010 to 2014. Airborne microbial contaminations in the shopping mall were measured during summer and winter on weekdays and weekend-days. Species of the airborne bacteria was identified by the 16S rDNA sequence analysis.
