冷链装备制冷剂相关温室气体减排研究进展

To promote sustainable development and energy saving and emission reduction of cold chain equipment, based on freezing equipment, refrigerating equipment, refrigeration transportation equipment, refrigeration sales equipment, and domestic refrigerator, combined with the refrigerant charge volume, leakage rate, and recovery rate, the development history of refrigerants was summarized, and the influence of refrigerant replacement on related greenhouse gas emissions was summed up. The results show that natural refrigerants, HCs, and HFOs have broad application prospects in cold chain equipment. The implementation of the three types of refrigerant alternatives can achieve about 5%, 20%, and 10% improvement in energy saving and emission reduction, respectively. In terms of refrigerant charging, leakage and recovery, there are still many gaps in existing research, such as unclear mechanisms and unverified effects. Research and development of efficient and environmentally friendly refrigerants and improvement of refrigerant recovery systems of cold chain equipment have become the focus of current research.
