title: [ESTIMATION OF THE EFFICIENCY OF THE TREATMENT OF SPLIT-SYSTEMS IN RESIDENTIAL AREAS IN ORDER TO REDUCE THE LEVEL OF THE PREVALENCE OF DISEASES OF THE RESPIRATORY SYSTEM].
abstract: The purpose of work: comparison of prevalence among residents, which use or fail to use to clean split systems.
  
  
  METHODS
  Collected information about morbidity rate in 235 cases people during 3 years.
  
  
  RESULTS
  The usage of split-systems without their regular cleaning leads to the gain in the level of the prevalence of respiratory diseases by 172.7% if compared with persons, who have no air conditioning systems at home. Also, the average number of disability days increases by 218.1%) and average time of the duration of the disease increases by 71.9%. The annual treatment of split-systems and regular cleaning of filters allowed to reduce the number of diseases. In comparison with the group of people, who fail to clean air conditioning systems, the drop of morbidity rate by 56.6%, average number of disability days by 63.3% and average time of diseases by 30.9% was observed. Regular treatment of air conditioning systems cannot completely repay the morbidity rates to the level of the control group. In comparison with the people, who use no air conditioning systems, the owners of split-systems with regular treatment have lung diseases by 18.4% more often. The average number of disability days and the average time of diseases increased by 16.9% and 18.8%. These changes can be explained by the impact of unfavorable (cooling) microclimate.
  
  
  CONCLUSIONS
  The impact of split-systems on the health of the population requires a comprehensive study and the subsequent development of normative documents regulating their safe use.
