摘要：A extraction device (5) for a refrigerating machine (1) removes non-condensed

gas (G) present in the refrigerating machine (1). The extraction device (5) is provided with:

an 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) capable of blocking 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 of the extraction tank (61) to

flow into the auxiliary tank (62).
