Summary:The purpose of the present disclosure is to provide: a composition in which the polymerization of refrigerant is suppressed; a preservation method; and a polymerization-suppressing method. This composition containing (1) a refrigerant and (2) oxygen is characterized in that the concentration of the (2) oxygen is, in terms of volume, at least 1 ppm at a temperature of 25ºC. L'objectif de la présente invention est de fournir : une composition dans laquelle la polymérisation du réfrigérant est supprimée ; un procédé de conservation ; et un procédé de suppression de polymérisation. Cette composition contenant (1) un réfrigérant et (2) de l'oxygène est caractérisée en ce que la concentration de l'oxygène (2) est, en termes de volume, d'au moins 1 ppm à une température de 25 °C. 本開示は、冷媒の重合が抑制された組成物、保存方法及び重合抑制方法を目的とする。 (1)冷媒と(2)酸素とを含む組成物であって、前記(2)酸素は、体積基準で、温度25℃で、濃度が1ppm以上である、ことを特徴とする組成物。
