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.
