PROBLEM TO BE SOLVED: To obtain the subject product capable of preventing lowering of purity of a refrigerant during storage and corrosion of a container over a long period by including a solid absorbent together with a refrigerant comprising a hydrogen-containing fluorocarbon in a non returnable container. SOLUTION: This refrigerant product is obtained by including a refrigerant selected from hydrofluorocarbon and hydrochlorofluorocarbon and a solid absorbent consisting essentially of a silica-alumina-based absorbent into a small-sized non-returnable can for supplement or a non-returnable portable container, etc. The solid absorbent is preferably sealed in a bag which is permeable to the refrigerant. A filter which is permeable to the refrigerant is preferably installed in a refrigerant output port. Water content, acid content and organic evaporation residual content contained in the refrigerant are retained in an amount of <=20 wt.ppm, <=0.2 wt.ppm and <=20 wt.ppm, respectively. Thereby, high-purity refrigerant which has not been realized hitherto in conventional refrigerant products packed in non-returnable containers is readily obtained. |
