The purpose of research - development concepts of combined electrical (mechanical) energy, heat and cooling in the vessel and stationary power plants by intracycle transformation of waste heat using low-temperature cycles of ozone safety refrigerants, providing reduced fuel consumption (5...10%) and increasing output power (10...15%). The object of research - the process of recycling waste energy potential of engines and power plants.The fundamental problem to be solved: The use of waste energy potential of marine and stationary power under conditions of limited amounts of waste heat or use for external heat and cooling and the operation in the climatic conditions of Ukraine to improve fuel efficiency by transforming heat with the new principles - the use of low-temperature refrigerant cycles, identifying characteristics and patterns of implementation as the basis of the concept of combined energy intracycle (for the needs of power plants) trigeneration. The results of research. 1. The complex of physical and mathematical models of the processes of intra-cycle transformation of waste heat of power plants was developed. 2. Analytical dependencies to determine the thermal coefficients of the advanced stage-cascade cycles of the waste heat transformation into the cold and the principles of rational organization of thermophysical processes in the power and heat pump (refrigeration) thermodynamic cycles, and methods for determining their optimal parameters have been developed. 3. The consistent patterns of the processes of low-temperature transformation of the waste heat of power plants in different climatic conditions that affect the operating features of the stages of thermal transformers of a combined type that depending on the cooling depth of the inlet air are determined. 4. The efficiency of the use of thermal transformers of a combined type with an absorption (water) high-temperature stage and a low-temperature freon stage, providing deep heat utilization, reducing fuel consumption, increasing the generation of mechanical or electrical energy is shown. 5. A methodology for evaluating the efficiency of cooling the cyclic air at the input of power plants that depends on the operating conditions based on the thermal-hourly (degree hours) potential has been developed.
