<P>PROBLEM TO BE SOLVED: To provide a refrigerator which is able to suppress the deterioration of components used in the refrigerant cycle, and operate stably over a long period, by efficiently trapping oligomers produced by polymerization of the hydrofluorocarbons, which are the refrigerant. <P>SOLUTION: The refrigerator, in which a refrigerant having a hydrofluoro olefin having a double bond between a carbon and a carbon as a base component and mixed with a hydrofluoro carbon having no double bond is circulated, includes: a refrigerant circulation path in which the refrigerant circulates from a compressor 1 through a condenser 2 or 4, an expansion mechanism 3 and an evaporator 4 or 2 to the compressor 1; and a strainer 8 having a fibrous filter which can trap an organic solid polymer in the refrigerant circulation path. <P>COPYRIGHT: (C)2012,JPO&INPIT |
