Abstract
The results of the development of the main stages of complex methods for studying the efficiency of heat recovery systems based on the exergy approach are presented. The choice of multiplicative criteria for evaluating the efficiency of heat recovery systems is included as a stage common to all methodologies. Criteria for evaluating the efficiency of systems that are highly sensitive to changes in the regime and design parameters of heat recovery systems and can serve as target optimization functions are proposed. The main stages of complex methods based on the exergy approach for heat recovery systems of various types have been developed. Methods are considered in which the methods of exergy analysis, statistical methods of planning an experiment, structurally variant methods and methods based on the calculation of exergy dissipators are used.
