The purpose of the work is to develop scientific principles and methodology for designing energy efficient heat recovery systems for cogeneration units of factories with integrated energy supply. The efficiency of transformation of waste heat of the cogeneration units on the basis of gas engines of factories with integrated energy supply is analyzed. The concept of waste heat recovery of cogeneration units of factories with integrated energy supply by using multi-stream systems of stepped transformation of waste heat into cold, which ensure the thermal state of engines at a safe level, minimize thermal losses during heat transformation into cold, is developed. Mathematical models and methods of calculation of processes of stepped transformation of waste heat of cogeneration units into cold in thermal transformers of absorption and adsorption types have been developed taking into account their joint work. Schematic solutions with corresponding principles of rational organization of processes are developed. The field of application of the results of the study is cogeneration units based on gas and turbine engines and other facilities of stationary and transport energy. The main technical and economic indicators: reduction of heat losses with its further transformation into cold leads to an increase in the cooling capacity of the installation by 15… 20% and an increase in the thermal coefficient from 0.55 to 0.7, ie the efficiency of the system by 20… 25% Product Description popup.authors Kornienko Viktorya S.
