    • PURPOSE: A cryogenic refrigerating system is provided to use an MGR(Mixed Gas Refrigerant) system, without fitting the volume of the MGR to the peak refrigerating requisites of a heat load and without adding an additional reliable system to the MGR system. CONSTITUTION: A cryogenic refrigerating system as an apparatus for providing refrigerating to a heat load comprises a heat load; at least one compressor(2); an auto-refrigerator heat exchanger(12); an expansion device; a unit for passing multi-component refrigerant fluid from the compressor(s) to the auto-refrigerator heat exchanger, from the auto-refrigerator heat exchanger to the expansion device, from the expansion device to the heat load, and from the heat load to the auto-refrigerator heat exchanger; and a cryogenic liquid storage tank(22) and a unit for passing cryogenic liquid from the cryogenic liquid storage tank to the heat load. The heat load includes a food freezer(16).
    • 目的:提供低温制冷系统,以使用MGR(混合气体制冷剂)系统,而不将MGR的体积装配到热负荷的最高制冷要求中,并且不向MGR系统增加额外的可靠系统。 构成:作为用于向热负荷提供制冷装置的低温制冷系统包括热负荷; 至少一个压缩机(2); 一个汽车冷冻热交换器(12); 膨胀装置; 用于将多组分制冷剂流体从压缩机传递到自动冷冻机热交换器的单元,从自动冷藏热交换器到膨胀装置,从膨胀装置到热负荷,以及从热负荷到 汽车冷冻热交换器; 和低温液体储存箱(22)和用于将低温液体从低温储液罐传送到热负荷的单元。 热负荷包括食品冷冻机(16)。
