Abstract

The invention relates to an integrated energy supply system of carbon dioxide energy storage and organic Rankine cycle that can realize combined cooling, heating and power supply. In the energy storage stage, the system uses surplus electricity to complete the conversion and storage of electric energy to heat energy, cold energy, and carbon dioxide pressure energy. In the energy release stage, it can use carbon dioxide expansion and energy release, organic Rankine cycle, etc. The heat storage and cold storage units complete the heat and cold energy supply for users. In order to improve the simultaneous supply capacity of cold, heat and electricity to users, the system also adopts the cold energy of LNG, and utilizes its cold energy in stages. The system can use renewable energy as the power source to realize the integration and joint application of the energy storage system and the organic Rankine cycle system. There is no pollutant emission during the energy supply stage, and it has good energy-saving and environmental benefits.

Description

technical field [0001] The invention belongs to the field of combined cooling, heating and power technology and energy storage technology, and relates to an integrated energy supply system that can realize combined cooling, heating and power, specifically, a carbon dioxide energy storage system that can realize combined cooling, heating and power Integrated energy supply system with organic Rankine cycle. Background technique [0002] With the depletion of traditional energy sources, today's society has higher and higher requirements for energy utilization. How to improve the efficiency of energy utilization, improve the quality of energy utilization, and realize the diversification of energy utilization has become the focus of global attention. Among the many energy utilization methods, CCHP (Combined Cooling, Heating and Power) mode is considered to be a significant energy utilization method, which can maximize the efficiency of energy utilization and meet the needs of pe...
