“Under the background of the "dual carbon" strategy, researchers have constructed a low-carbon combined cooling, heating, and power system with coupled heat pump technology. By optimizing energy cascade utilization through multi-stage waste heat recovery and coordinated matching of temperature zones, a multidimensional evaluation model covering thermodynamics, environmental friendliness, economy, and economic performance has been established, providing theoretical support for solving the problem of efficient and low-carbon operation of traditional energy systems.”
