DEVELOPMENT OF A METHODS FOR MULTILEVEL OPTIMIZATION OF HEAT RECOVERY SYSTEMS

The work is devoted to the optimization of complex heat recovery systems for which it is not possible to establish general analytical dependencies of the optimization objective functions on the system parameters. For such systems, a comprehensive multilevel optimization technique is proposed and the basic principles of its development are outlined. A diagram illustrating the main stages of the methodology is provided. For heat recovery systems the criteria for evaluation of their exergy efficiency have been developed, which have high sensitivity to changes in mode and design parameters and serve as objective optimization functions. The proposed methodology improves the optimization efficiency and exergy efficiency of the system.
