| 摘要: |
| 制冷剂回收和再生是减少制冷剂排放的推荐方式，但其实施有赖于政策的鼓励及回收再生技术的支持。对于制冷剂的回收，本文总结对比了日本、欧盟、美国和中国在制冷剂回收方面的政策，给出了各自的制冷剂年回收量；介绍了制冷剂回收5种代表性方法的工作原理、优缺点及适用的场合。对于制冷剂的再生，介绍了“简易再生”和“蒸馏再生”这2种再生方法的步骤和应用条件；以及对于不可再生制冷剂进行销毁的7种方法。最后，总结了中国目前在制冷剂回收再生中所面临的主要问题。 |

| Abstract: |
| The recovery and reclamation of refrigerants is a recommended method of reducing refrigerant emissions, which requires technical support and policies to stimulate the activity. In this study, the policies for supporting refrigerant recovery as well as the quantity of recovered refrigerants reported in Japan, EU, USA, and China are summarized and compared, and the working principles, advantages, disadvantages, and recommended application conditions of five representative recovery methods are described in detail. For the reclamation of refrigerants, the procedures and application conditions of two reclamation methods, that is, simple distillation and distillation refinement, are explained, and seven destruction methods for non-reclaimable refrigerants that need to be destroyed are described. At the end of this paper, the main problems regarding refrigerant recovery and reclamation in China are presented. |
