Indoor Bacterial Removal by an Absorption Dehumidification System
(0) The evaluation of bacterial removing efficiency for indoor bioaerosols by an absorption dehumidification system was investigated in this study. The comparison of two liquid desiccant dehumidifier, TEG (Triethylene glycol) and LiCl (Lithium chloride), was also illustrated. Two one-stage Anderson samplers of 400 orifices attached to tryptic soy agar (TSA) plates with cycloheximide addition were installed in the inlet and outlet of the absorption dehumidification system to collect viable bacteria. The results showed that the best bacterial removing efficiency, 94.3%, is for TEG system under the condition: air flow rate 1.5 kg/m2, liquid flow rate 4.97 kg/m2, liquid inlet concentration 89.5% and liquid inlet temperature 24.5 Contrary to TEG system, the least bacterial removing efficiency, 27.1% is for LiCl system under the condition: air flow rate 1.5 kg/m2, liquid flow rate 4.97 kg/m2, liquid inlet concentration 39.5% and liquid inlet temperature 35.7 However, most of the bacterial removing efficiency for LiCl system is higher than it for TEG system.
