RESUMO
Modern ventilation and air conditioning systems are complex technological objects in environment which can be sources of health-hazardous factors, including biological ones. Ventilation and air conditioning contact systems with water and partial air recirculation have construction prerequisites for environmental accumulation and dispersal of organic substances of microorganism and anthropogenic origin. Pollution substrates of inner surfaces of the above systems contain specific antigens causing immune response in persons working in air-conditioned premises.

Pollution of air ventilation and conditioning systems by microorganisms and products of their activity can lead to the development of infectious (legionnaires' disease) and allergic (humidifier fever) diseases. Clinical, immunological and hygienic investigations under natural conditions of 72 persons working in offices helped to study a respiratory disease which was similar to humidifier fever. The removal of dust and mud from the system and thorough cleaning of all conditioned rooms put an end to this disease.
