Abstract: The amount of low-temperature heat generated in industrial processes is high, but recycling is limited due to low grade and low recycling efficiency, which is one of the reasons for low energy efficiency. It implies that there is a great potential for low-temperature heat recovery and utilization. This article provided a detailed review of recent advances in the development of low-temperature thermal upgrades, power generation, refrigeration, and thermal energy storage. The detailed description will be given from the aspects of system structure improvement, work medium improvement, and thermodynamic and economic performance evaluation. It also pointed out the development bottlenecks and future development trends of various technologies. The low-temperature heat combined utilization technology can recover waste heat in an all-round and effective manner, and has great development prospects.

Key words: Low-temperature heat, Heat pump, Power generation, Heat storage, Refrigeration
