Abstract. The samples of air were taken in 122 shops with the split air conditioning systems. The unfavorable changes of air quality were detected after switching of air-conditioning systems. Before switching of the air-conditioning systems, the provisionally pathogenic and pathogenic bacteria in the air were presented in 6.4% of samples, the mould fungi — in 27.8%, the yeast fungi — in 5.7%. After 30 minutes of split-systems operation, the provisionally pathogenic and pathogenic bacteria were found in 97.5% samples, mould fungi — in 72.1% and the yeast fungi — in 27.9%. Moreover, the species diversity of microorganisms in indoor air, after switching of split-system, was fully corresponded (100%) to the microflora of biofilms in internal block of the split-systems. Variants, in which microorganisms isolated from the biofilm in the condensate removal system after the switching split-systems was absent in premises air, were not determined. Thus, the microflora, which forms the biofilm in the condensate removal system, is a source of air pollution in the premises, where the split system were installed.
Резюме. В помещениях 122 магазинов с установленными сплит-системами отбирались пробы воздуха. После включения систем кондиционирования отмечены негативные изменения в качественном составе воздуха. До включения систем кондиционирования условно-патогенные и патогенные бактерии присутствовали в 6,4% проб воздуха, плесневые грибы — в 27,8% проб, дрожжеподобные грибы — в 5,7%. После 30 мин работы сплит-систем условно-патогенные и патогенные бактерии обнаруживались в 97,5% проб воздуха, плесневые грибы — в 72,1% проб, дрожжеподобные грибы — в 27,9%. Кроме того, микроорганизмы, появившиеся в воздухе помещения после включения сплит-систем, соответствовали микрофлоре биопленки внутреннего блока сплит-систем в 100% случаев. Вариантов, при которых микрофлора, выделенная из биопленки системы удаления конденсата сплит-системы, отсутствовала бы в воздухе помещения после ее включения, не выявлено. То есть микрофлора, образующая биопленку в системе удаления конденсата, гарантированно является источником загрязнения воздуха помещения. |
