Summary

The main source of biological contamination of air-conditioned spaces is the drip trays under air-conditioning evaporators. The water films create an ecosystem that helps germs grow. Pressure and air-speed conditions lead to contamination of aerosols within the air-conditioned rooms, especially in offices. The article describes the properties of the microbial flora found during tests in offices in Sao Paulo, Brazil.
