Description
technical field [0001] The invention relates to the field of new energy, in particular to a closed Brayton cycle binary engine system. Background technique [0002] As environmental pollution, smog and other problems become more and more serious, fossil energy is being questioned more and more frequently, and various green energy sources have been highly anticipated since the day they were developed. Solar thermal power generation is an important direction of new energy utilization. Compared with photovoltaic and wind power, it has the advantages of heat storage and energy storage. At present, in the solar thermal power generation system based on the Rankine cycle, a phase change will occur during the cycle, and the absorption and release of heat are concentrated in the temperature range of the phase change. The energy release process is too concentrated and congested, resulting in equipment costs. increase, low energy utilization and a series of problems. Therefore, it is...
