Annotation

One of the factors influencing the efficiency of animal husbandry is the conditions of keeping animals, in which ensuring an optimal microclimate is important. The traditional provision of an optimal microclimate for animals in order to obtain high productivity from them is associated with high costs of heat and electricity, which costs up to 15% of the producers. Therefore, the issues of improving energy-saving systems to ensure the microclimate in livestock facilities are always relevant and require scientific justification. The purpose of the research is to increase the efficiency of providing the microclimate in piggeries by substantiating the composition of the energy saving system for its implementation. As a result of a review of studies of the influence of microclimate parameters on the physiological state of pigs, it was found that their productivity is most affected by temperature and humidity in the room for their maintenance. Given the technological conditions of air in livestock premises (significant dust - up to  3,5 mg/m3, humidity - 40-70%, the presence of a high concentration of aggressive components - ammonia 20-30 mg/m3, hydrogen sulfide - 10-15 mg/m3, carbon dioxide gas – 0,2-0,35%) and the results of the analysis of heat recovery structures, heating and cooling systems, it was found that the sanitary and hygienic and operational indicators, high energy efficiency and low cost of construction are the most suitable for ventilation systems with tube heat exchangers with additional heating and adiabatic cooling. To ensure the microclimate in livestock facilities, a constructive-technological scheme of energy-saving system for providing microclimate in piggeries for different sex and age groups of animals has been developed.

Keywords: pig premises, microclimate, energy saving systems, heat utilizers, adiabatic cooling, temperature, humidity.

History of journal:

In June 1994 the 2nd International Scientific and Technical Conference "Application of vibrations for technological purposes" was organized on the basis of Vinnytsia State Agricultural Institute. Leading experts in this field, noting the significant contribution to the school of Vibration Engineering under the leadership of P. S. Bernyk, proposed to create a professional all-Ukrainian scientific and technical journal "Vibration in engineering and technology..The journal was foundedat Vinnytsia State Agricultural Institute and P.S. Bernyk was elected to be the chief editor .
For all these years (since 1994) theJournal "vibration in engineering and technology" published  94 issues wherestudy of vibration effects, the creation of progressive energy saving technologies and equipment for their implementation were highlighted.
Currently Kaletnik H.M  PhD , professor, academician NAAS is the chief editor of the "Vibrations in engineering  and Technology"
The journal "Vibration in Engineering and technology", which has no analogues on the territory of Ukraine, is well known abroad.
