Abstract: Disclosed is a refrigeration circuit-forming member which has a metal surface and is used for a refrigeration circuit in which HFO-1234yf that is a refrigerant configured of molecules having a double bond is used. The metal surface, which comes into contact with the HFO-1234yf, is covered with a coating layer that is not reactive with the HFO-1234yf within the range of temperature at which the HFO-1234yf is used. The coating layer is formed of any of a coating film that is firmly fixed to the metal surface, a coating layer that is formed by adhesion of a specific component added into the lubricant oil, and a coating layer that is formed by modification of the metal surface layer itself that forms the metal surface. Consequently, the chemical instability that is caused when the refrigerant HFO-1234yf comes into contact with the metal can be eliminated.
