Title:
冷媒回収装置および冷媒回収方法
Document Type and Number:
Japanese Patent JP6682880
Kind Code:
B2
Abstract:
A refrigerant recovery system (90A) is equipped with an extraction pipe (61), a stabilizer holding container (70), a recovery pipe (62), a recovery container (80), and a recovery device (85). The extraction pipe (61) is connectable to a refrigerant extraction port (18) of an air conditioning apparatus (100). The stabilizer holding container (70) is connected to the extraction pipe (61) and holds a stabilizer (A). The stabilizer holding container (70) causes refrigerant guided by the extraction pipe (61) to come into contact with the stabilizer (A). The recovery pipe (62) guides the refrigerant discharged from the stabilizer holding container (70). The recovery container (80) is connected to the recovery pipe (62) and recovers the refrigerant guided by the recovery pipe (62). The recovery device (85) causes the refrigerant to move from the refrigerant extraction port (18) to the recovery container (80). The refrigerant includes a compound represented by a molecular formula having one or more carbon-carbon unsaturated bonds.
