Research on Refrigerant Retrieval of Refrigerators and the Relevant Use

We can conveniently retrieve refrigerant of refrigerators by physical methods. This article introduces the principle and arrangement of the refrigerant retrieval technique, discusses the details and results, analyses the process and finds ways to solve safety problems and quality problems of retrieved refrigerant. The retrieved refrigerant can be used again. The analysis makes it clear that the method in this article is suitable not only for retrieving new-type refrigerants but also for other types of refrigerator. This technique is a good substitute for the manual emission craft, which has been a long-standing problem in the refrigerator service. This technique is again suitable for retrieving gas or liquid from other sealed systems. So it can be used in other cases of environmental protection, safety and emergency.
