They allow to identify thermophysical characteristics of a solid and to obtain complex dependences of heat flows based on a thermophysical experiment presented with some errors. The methods of thermodynamic analysis and thermoeconomic optimization of thermal transformers operating on a subcritical and transcritical cycle are developed, taking into account seasonal changes in their operating modes and the influence of changes in air humidity. A thermodynamic cycle and a thermal scheme of a cogeneration cooler with heat regeneration of the refrigeration cycle of an absorption thermal transformer are proposed. An approach to increasing the efficiency and reliability of operation of high-power turbine flow path elements is developed. The analysis of the operating modes of a CHPP steam condenser is carried out taking into account changes in the last-degree power in low-cost modes. A mathematical model of thermal processes in a dry storage facility for spent nuclear fuel is proposed and a technique for determining boundary conditions and equivalent thermophysical properties for computational domains of different levels of detail is developed.
