| Popis: | An analysis ofthe energy consumption structure in Ukraine shows that it is necessary to take into account the current global trends in energy efficiency during the post-war restoration of such key energy infrastructure facilities as heat and electricity generation heathydro-aerodynamic systemsand water supply ventilation air conditioning.etc. However the analysis of existing information technologyfor computer-aided design of energy facilities which are based on hydro-aerodynamicsystems.Showedthat the models and methods of structural and parametric synthesis of components of hydro-aerodynamicsystems (generating energetically active basic elements and network energetically passive auxiliary elements)do not fully take into account the influence of the state of real hydro-aerodynamicprocesses in the formation of a base of typical design solutions of elements. This leads to a decrease up to40%of the energy efficiency of the designed infrastructure facilities. Therefore the development of structural-parametric models of energy-efficient hydro-aerodynamicsystems and the creation on their basis of an appropriate information technology integrated in engineering computer-aided designis especially relevant during the post-war restoration of Ukraine energy infrastructure facilities. When developing structural-parametric models of energy-efficient hydro-aerodynamicsystems.Thefollowing tasks were solved: based on a comparative analysis of the possibilitiesof structural.Parametricand structural-parametric synthesis of energy-efficient hydro-aerodynamicsystems to create information technologies integrated in machine-building and engineering computer-aided designsystems.a structural parameter was reasonably chosen; structural-parametric models of an energy-efficient hydro-aerodynamicsystem and its components (network and generating parts)have been developed; a logical-numerical model for generating technical proposals for the structural-parametric synthesis of energy-saving hydro-aerodynamicsystems taking into account the advantages of using the topological properties of graph models in the space-time domain has been developed; the definition of additional target parameters of the structural-parametric model of the hydro-aerodynamicsystem is proposed. The developed models were used to create an information technology for the structural-parametric synthesis of energy-saving hydro-aerodynamicsystems integrated in computer-aided design.Approbation of theproposed information technology showed that the reduction of hydro-aerodynamicresistance in the network part of hydro-aerodynamicsystems made it possible to increase the energy efficiency of the synthesized hydro-aerodynamicsystemsfrom 25 to 45%. This was performed by reducing the energyexpended to provide the specified consumptionof the working fluid created by the main elements such as feed pumps blow fansandsmoke exhausters |
