Development of technical and technological schemes and control systems of heating systems based on thermodynamic approaches

Methodological, mathematical, algorithmic and software maintenance and support services have been developed and improved for optimizing structure, parameters and operation modes of new and improved solutions in heating systems based on renewable energy sources and energy efficient technologies (low-energy houses, low-temperature heating systems and high- temperature cooling systems, heat pumps and cogeneration plants, thermal storages, etc.). Improved criteria have been developed for simultaneous exergy, economic and environmental assessment (conventional and advanced) of the heating systems, taking into account the variable operation modes of the system components under different conditions of the reference point (above, below, or crossing the temperature of the environment). Mathematical and computer models of promising and innovative solutions for heating systems, methods and means of implementation of these models taking into account the proposed criteria of exergic evaluation and using modern information technologies (cloud calculations, digital twins, predictive diagnostics and control, etc.) have been developed and implemented. Based on the implemented numerical studies, the parameters, structures, characteristics, technical and technological solutions of heating systems for desing and operation conditions have been proposed for improving their energy, economic and environmental efficiencies.
