PROBLEM TO BE SOLVED: To provide a pipe connecting method capable of efficiently connecting a pipe with a refrigerating machine using a combustible refrigerant in safety, while preventing ignition by the combustible refrigerant even in a state in which the combustible refrigerant is filled up. SOLUTION: In this pipe connecting method in the refrigerating device using the combustible refrigerant, the pipe of the refrigerating machine using the combustible refrigerant is connected by means of brazing filler metal or adhesive agent. A melting point of the brazing filler metal or an adhesion temperature of the adhesive agent is lower than an ignition point of the combustible refrigerant. COPYRIGHT: (C)2005,JPO&NCIPI
