    摘要： A refrigeration system includes first and second refrigerant circuits each having a compressor, a condenser and an evaporator, each of the refrigerant circuits being charged with an organic refrigerant. The evaporator of the first refrigerant circuit is divided into a plurality of evaporator portions connected together in series. The condenser of the second refrigerant circuit is divided into condenser portions equal in number to the number of the evaporator portions of the first refrigerant circuit. The condenser portions of the second refrigerant circuit are paired with the evaporator portions of the first refrigerant circuit to provide heat exchangers. The refrigerant of the second refrigerant circuit is a mixture of refrigerants different in kind and in boiling point.

    摘要： There is disclosed a refrigerating apparatus which can more efficiently cool the inside of a chamber to an ultralow temperature. In a refrigerating apparatus R1 which condenses a refrigerant discharged from a compressor 14, reduces a pressure of the refrigerant by a capillary tube 18 and evaporates the refrigerant by an evaporator 13 to exert a cooling function, the capillary tube 18 is passed through a suction piping line 32 through which the refrigerant returning from the evaporator 13 to the compressor 14 flows, to constitute a double tube structure. Furthermore, the suction piping line 32 (a piping line 32A) formed in the double tube structure by passing the capillary tube 18 therethrough is surrounded with an insulating material 35.
