`
`LISTING OF CLAIMS
`
`1. (Currently Amended) A refrigerating apparatus comprising:
`
`a refrigerating cycle including a compressor, a condenser, a flow divider, a first heat
`
`exchanger, a second heat exchanger, a decompressing device, and an evaporator, connected
`
`circularly with a refrigerant piping, the refrigerant cycle having sealed therein a mixed refrigerant
`
`obtained by mixing at least first to third refrigerants with different evaporation temperatures,
`
`the first heat exchanger and the second heat exchanger each including a double pipe to form
`
`a first flow passage in an inner pipe of the double pipe, a second flow passage in an outer pipe of the
`
`double pipe, and an intermediate port in a piping connecting between the second flow passage of the
`
`first heat exchanger and the second flow passage of the second heat exchanger,
`
`a high-temperature and high-pressure refrigerant discharged from the compressor being
`
`cooled by the condenser to liquefy the first refrigerant having a high evaporation temperature into a
`
`liquid refrigerant, and thereafter,
`
`the liquid refrigerant obtained by dividing a refrigerant in the flow divider being
`
`decompressed, and thereafter supplied to the second flow passage of the first heat exchanger via the
`
`intermediate port, evaporated toward one port of the second flow passage, and supplied to a sucking
`
`side of the compressor via the one port of the second flow passage of the first heat exchanger,
`
`a gas—state refrigerant obtained by dividing a refrigerant in the flow divider being supplied to
`
`the first flow passage of the first heat exchanger, and thereafter passing through the first flow
`
`passage to liquefy the second refrigerant with an evaporation temperature lower than the
`
`evaporation temperature of the first refrigerant, and thereafter passing through the first flow passage
`
`of the second heat exchanger to liquefy the third refrigerant, and thereafter, via the decompressing
`
`device, passing through the evaporator to evaporate the second and third refrigerants, and thereafter
`
`passing through the second flow passage of the second heat exchanger and the second flow passage
`
`of the first heat exchanger, and thereafter departing from the other port of the second flow passage
`
`of the first heat exchanger via the one port and arriving at the sucking side of the compressor, and
`
`thereby

`

`Application No.: 12/835,568
`
`Docket N0.: 092122-0013
`
`a refrigerant in the first flow passage of the first heat exchanger and the second heat
`
`exchanger and a refrigerant in the second flow passage of the first heat exchanger and the second
`
`heat exchanger having a countercurrent relationship, and having a temperature relationship in a
`
`manner that the refrigerant flowing through the second flow passage cools the refrigerant flowing
`
`through the first flow passagel
`
`wherein a part of the third refrigerant is_e\_/ap_orated in the second flow passage of the second
`
`heat exchanger, and
`
`the decompressing device includes a capillary tube: and the capillary tube is wound around a
`
`pipingextending from the evaporator to the second heat exchanger.
