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 directions using waste heat capacity of power plants by intracycled low-temperature refrigerant trigeneration in combined cycles in the climatic conditions of Ukraine. Unlike existing methods of intracycled low-temperature refrigerant trigeneration cooling cyclic air heat engines power plants to moderate temperatures of 15...20°C through the transformation of waste heat in absorption chillers, effective for hot climatic conditions reasonably direction of low-temperature refrigerant trigeneration with deep cooling cyclic air engine power plants to a temperature of 7...10°C by a two-stage transformation of waste heat in the cold in the combined thermodynamic cycle for low-temperature refrigerants (freons) that provides 1.5…2 times greater fuel savings for use in Ukraine climate conditions compared with existing methods of waste heat capacity of power plants. 2. Grounded methodological approach to the use of waste heat capacity of power plants by intracycled trigeneration cooling cyclic air of heat engines: through a two-stage low-temperature transformation of waste heat in the cold in the combined thermodynamic cycle for low-temperature refrigerants, which unlike existing methods takes into consideration the thermal load changing respectively to Ukraine climatic conditions and provides maximum annual fuel savings.
