Abstract:

Objectives In recent years, organic Rankine cycle-vapor compression cycle (ORC-VCC) systems have made great progress in the fields of low-grade heat energy utilization and cooling and heating supply owing to their compact structure, low-carbon, and energy-saving advantages. Accordingly, focusing on three key aspects of cycle configuration, working fluid selection, and application directions, this study reviews the latest research progress in ORC-VCC systems. Methods Firstly, five different cycle configurations are outlined, and their principles and characteristics are elucidated to demonstrate the structural diversity and adaptability to operating conditions of ORC-VCC systems. Subsequently, the development history of working fluids is explored in depth, and the principles of working fluid selection are summarized from multiple dimensions such as thermophysical properties, environmental friendliness, and economic efficiency. The economic evaluation results of the systems in different studies are summarized, highlighting the importance of economic analysis. In addition, the potential application fields of the systems are summarized from both the supply and demand sides, and application cases of integration with other systems are presented, with a view to revealing the extensive research and application potential of ORC-VCC systems. Finally, the shortcomings of the current research are pointed out and the future research directions are prospected. Conclusions ORC-VCC systems have broad development prospects and huge development potential. Their application in the energy field will make important contributions to achieving low-carbon, energy-saving, and sustainable development goals.
