`
`AMENDMENTS TO THE SPECIFICATION
`
`Please amend the Abstract as follows:
`
`A binary refrigerating apparatus employs a refrigerant composition that has a small global—warming
`
`potential (GWP) to—be—earth—friendly, can be used as a refrigerant capable of achieving a low
`
`temperature of -80°CflW€H&%—%WWMWW.
`
`A
`
`refrigerant composition used as a low-temperature—side refrigerant is a refrigerant mixture including
`
`a non—azeotropic mixture in which 20% by mass or less of carbon dioxide (R744) is mixed to
`
`difluoroethylene (R1132a). A refrigerant composition used as a high-temperature—side refrigerant is
`
`a combination of: a non—azeotropic mixture comprising the refrigerant group of difluoromethane
`
`(R32), pentafluoroethane (R125), 1,1,1,2—tetrafluoroethane (R134a) and l,1,3~trifluoro ethane
`
`(R143a); and 1,1,l,2,3—pentafluoropentene (HFO—l234ze), having a global-warming potential
`
`(GWP) of 1500 or less.
