    • PROBLEM TO BE SOLVED: To provide an extraction device and an extraction method for a refrigerating machine that can prevent a non-condensed gas such as air and hydrogen from remaining in an extraction tank, and can prevent a back-flow of the non-condensed gas and outside air into the refrigerating machine.SOLUTION: The extraction device 5 for the refrigerating machine 1 removes the non-condensed gas G present in the refrigerating machine 1. The extraction device 5 includes the extraction tank 61 used to circulate a refrigerant A within an evaporator 31, circulation piping 8 circulating through both the extraction tank 61 and the evaporator 31, an extraction pump 71 for delivering the refrigerant A from the evaporator 31 to the extraction tank 61, a shutoff valve 72 that can block the flow of the refrigerant A from the extraction tank 61 to the evaporator 31, an extraction means 73 for extracting the non-condensed gas G present in the refrigerating machine 1 to the extraction tank 61, and an auxiliary tank 62 for allowing the refrigerant A saturated within the extraction tank 61 and spilling out to flow therein.
    • 要解决的问题:提供一种可以防止诸如空气和氢气的非冷凝气体残留在提取罐中的制冷机的提取装置和提取方法,并且可以防止 非冷凝气体和外部空气进入制冷机。 解决方案:用于制冷机1的提取装置5去除冷藏机1中存在的非冷凝气体G.提取装置5包括用于使制冷剂A在蒸发器31内循环的提取罐61,循环管道 8,循环通过提取罐61和蒸发器31的抽出泵71,用于将制冷剂A从蒸发器31输送到提取罐61的抽取泵71,可以阻止制冷剂A从提取罐61流出的截止阀72 向蒸发器31提供用于将存在于冷冻机1中的非冷凝气体G提取到提取槽61的提取装置73以及用于使制冷剂A在提取罐61内饱和并溢出流出的辅助罐62 在其中。 版权所有(C)2013,JPO&INPIT
