本発明は二元冷凍装置に係シ、特に低温側冷凍サイクル
における複数の蒸発器に冷媒を均一に流通させる構造に
関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a binary refrigeration system, and particularly to a structure for uniformly circulating a refrigerant to a plurality of evaporators in a low-temperature side refrigeration cycle.

冷凍サイクルとを組合せた構成となっている。To explain a conventional binary refrigeration system with reference to FIG. 1, there is a high temperature side refrigeration cycle consisting of a high temperature side compressor 1, a condenser 2, a capillary tube 3, and a cascade condenser 4, a low temperature side compressor 5, the cascade condenser 4, It has a configuration in which a low-temperature side refrigeration cycle consisting of a capillary tube 6, an evacuator 7, and an accumulator 8 are combined.

４のコンデンサ部４ Ａで低温側冷凍サイクルの冷媒と
熱交換して蒸発し、再び高温側圧縮機１に戻る。という
サイクルを繰り返す。In the high-temperature side refrigeration cycle, the refrigerant discharged from the high-temperature side compressor 1 is condensed and liquefied in the condenser 2, and after being depressurized in the capillary tube 3, the refrigerant is transferred to the condenser section 4A of the cascade condenser 4 in the low-temperature side refrigeration cycle. It exchanges heat with the refrigerant, evaporates, and returns to the high temperature side compressor 1 again. Repeat this cycle.

The discharged refrigerant is condensed and liquefied in the condenser part 4B of the cascade condenser 4, and after being depressurized in the capillary tube 6, it is evaporated by exchanging heat with the object to be cooled in the evaporator 7, and returns to the low-temperature side compressor 5 again. Repeat this cycle.
ところで、前述の蒸発器７が図示のように２台ある場合
には冷媒の分岐は、各々の蒸発器７の容量に応じたキャ
ピラリチューブ６の手前で行う。By the way, when there are two evaporators 7 as shown in the figure, the refrigerant is branched before the capillary tube 6 according to the capacity of each evaporator 7.
しかるにキャピラリチューブ６は冷媒の流量を調整する
自己調整作用があり、キャピラリチューブ６０手前が過

要とする冷媒量が流れなくなり、極端の場合には片方の
蒸発器７に冷媒が全く流れなくなりで、冷却不良のトラ
ブルを起すことがある。However, the capillary tube 6 has a self-adjusting function that adjusts the flow rate of the refrigerant, and if the part before the capillary tube 60 is in a supercooled state, there is no problem in branching the refrigerant, but the part before the capillary tube 6 is in a two-phase flow in the saturated region. If this happens, the refrigerant will not be branched smoothly. In other words, the required amount of refrigerant will no longer flow to each evaporator 7, and in extreme cases, no refrigerant will flow to one of the evaporators 7 at all, which may result in poor cooling.

したことを特徴とする。To achieve this objective, the dual refrigeration device of the present invention:
The condenser section of the cascade condenser through which the refrigerant of the low-temperature side refrigeration cycle flows is divided into a number corresponding to the number of evaporators, and the inlet of each condenser section is connected to the discharge side of the low-temperature side compressor. It is characterized in that the outlet is connected to the inlet side of the capillary tube corresponding to each evaporator.

The figure shows a cycle system diagram of a binary refrigeration system according to the present invention, and the same reference numerals as in FIG. 1 represent the same or equivalent parts. In this binary refrigeration system, the condenser section of the cascade condenser 4 through which the refrigerant of the low temperature side refrigeration cycle flows is divided into a number corresponding to the number of evaporators 7. That is, the condenser part of the cascade condenser 4 is divided into two condenser parts 4c and 4D, each of the condenser parts 4c and 4D is connected to the discharge side of the low temperature side compressor 5, and the outlet is connected to the two evaporators.

る。Next, the operation of the present invention will be explained. In the low-temperature side refrigeration cycle, the refrigerant discharged from the low-temperature side compressor 5 branches into two directions in the superheated gas region before the cascade condenser 40 and flows into the condenser section 4C14D. At this time, since the refrigerant is in a one-phase region, branching to the condenser parts 4G and 4D is performed well. The refrigerant that has flowed into each condenser section 4C14D is condensed and liquefied here, and then flows into the evaporator 7 after being adjusted to a flow rate according to each evaporator 7 in the capillary tube 6.
従って、各蒸発＠７では常に必要とする冷媒流量を得ら

達成できる。In addition, although the above-mentioned embodiment was shown as an example equipped with two evaporators 7, in the case of an embodiment equipped with three or more evaporators, the condenser section of the cascade condenser 4 may be divided according to the number of evaporators. By doing so, the same effect as described above can be achieved.
