Scientific work is devoted to experimental research, aimed at improving the efficiency of contact heat and mass transfer units by increasing the interfacial surface of heat and mass transfer during the liquid spraying by centrifugal nozzles, implementation of which results in significant savings of material and energy resources.
Full-scale development in Ukraine of a huge potential for energy saving due to the utilization of the heat of exhaust gases of industrial power and technological units that use hydrocarbon fuels is impossible without deep cooling of these gases in condensing heat exchangers.
Energy management systems in different universities of Ukraine were considered. Procedures for conducting energy audits for social facilities and estimation of baseline buildings energy consumption for evaluating the implementation of energy saving measures were developed. Mathematical models of building thermal condition were created, taking into account the influence of solar and thermal radiation, thermal protection, based on European standards (simplified hourly method 5R1C) and EnergyPlus software product. Intermittent operation of heating was investigated.
