doi:10.11949/0438-1157.20221644

Abstract

Abstract:

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.

Key words: cold chain equipment, refrigerant, energy conservation and emissions reduction, alternative solution, development suggestion

摘要：

为推进冷链装备的可持续发展与节能减排，针对冷链中的加工装备、运输装备、销售装备和冷冻冷藏装备等，结合制冷剂的充注量、泄漏率与回收率，对所用制冷剂的发展历程进行了综述，分析并总结了制冷剂替换方案对相关温室气体减排的影响。结果表明，自然制冷剂、HCs和HFOs在冷链装备中应用前景广阔，三类制冷剂替代方案的实施可分别取得5%、20%和10%左右的节能减排效果。在制冷剂充注、泄漏和回收等方面，既有研究还存在机理不明晰、效果待验证等多处研究空白，研发高效环保制冷剂并完善冷链装备制冷剂回收体系已成为目前重点研究方向。
