Registration Date 29-12-2021 Organization Institute of Engineering Thermophysics of NAS of Ukraine popup.description2 To develop methods of operation of air conditioning systems of modern energy efficient buildings of different types and purposes, as well as to prevent the instability of coolant flow in some hydraulic circuits, the main modes of operation of such systems were scientifically substantiated. The technical features of different variants of heat exchange equipment are analyzed: heaters of different design, ground heat exchangers - heat sources for the heat pump, as well as geothermal heat exchangers and heating circuits as components of the recuperative ventilation system. The possibility of using heat power plants based on pulsating (vibrational) combustion, in particular pulsating combustion boilers, for the needs of communal energy is analyzed. These boilers have a number of advantages, such as intensification of combustion, improved heat transfer and reduced heat transfer area, reduction of harmful emissions, etc., which make them attractive in the heat sector of the market. However, the widespread introduction of pulsating combustion devices in technological processes is constrained by the lack of a reliable theory of the working process for the calculation of design parameters in their design and taking into account the phenomena of instability. Algorithms for constructing periodic solutions of nonlinear dynamical systems with constant and variable delay arguments have been developed and used to control thermoacoustic oscillations and vibrational combustion. A model was created to visualize the combustion process of different types of pellet fuel in the burner, which allows you to visually control the combustion process and adjust combustion conditions by external influences (changes in pellet heating temperature, additional air supply to the combustion chamber), which determines the necessary conditions pellet fuel.
