  • Publication number: 20190032976
    Abstract: A refrigerant recovery system is equipped with an extraction pipe, a stabilizer holding container, a recovery pipe, a recovery container, and a recovery device. The extraction pipe is connectable to a refrigerant extraction port of an air conditioning apparatus. The stabilizer holding container is connected to the extraction pipe—and holds a stabilizer. The stabilizer holding container causes refrigerant guided by the extraction pipe to come into contact with the stabilizer. The recovery pipe guides the refrigerant discharged from the stabilizer holding container. The recovery container is connected to the recovery pipe and recovers the refrigerant guided by the recovery pipe. The recovery device causes the refrigerant to move from the refrigerant extraction port to the recovery container. The refrigerant includes a compound represented by a molecular formula having one or more carbon-carbon unsaturated bonds.
