The medium-low temperature waste heat is used as a proper heat source, and the medium-low temperature waste heat recovery power generation can be realized by utilizing the transcritical carbon dioxide circulation.

The circulation can utilize the medium-low temperature waste heat as the driving heat energy required by the circulation, and the recovery of the medium-low temperature waste heat is realized. The generated chilled water is used as a cold source of the transcritical carbon dioxide circulating power generation system, so that the power generation efficiency of the system is improved, and the cascade utilization of waste heat is realized.
