MICROORGANISMS OF THE CONDENSATE, FORMED IN THE SPLIT-SYSTEMS: EXPERIMENTAL RISK ASSESSMENT
https://doi.org/10.21886/2219-8075-2015-3-67-70
Abstract
Purpose: studying microorganisms from condensate, formed in air-conditioning systems, and assessment the possibility of elevation of aerosol to the ≪breathing zone≫ of the person.
Materials and methods: sampling of condensate from air conditioning systems; isolation of pure strains and his identification; modeling situation, when from split system, located on the second floor, streamed condensate with conditionally pathogenic bacteria.
Results: in condensate, formed in air-conditioning systems, conditionally pathogenic microflora families Enterobacteriaceae and Pseudomonadaceae, Staphylococcus aureus and Burkholderia cepacia founded. The experiment showed that fall of condensate drops on a solid surface formed aerosol. This aerosol contain microorganisms from condensate and can lifted by airflow at a height of 1.5 meters, to the breathing zone of an adult person.
Summary: to reduce the risk of the condensate contamination by conditionally pathogenic microflora regular cleaning and disinfection of air conditioning systems needed. To protect the health of casual passer from bacteria-contained aerosol, need to remove the condensate from air-conditioning system directly into the sewer system.
