PROBLEM TO BE SOLVED: To estimate the non-condensable gas quantity or gas concentration in a tank of an extraction device.SOLUTION: An extraction device 2 comprises: an extraction part 60 for extracting fluid mixture containing gas refrigerant and non-condensable gas from a condenser 40 of a refrigerating cycle 1; and a tank 70 for storing the fluid mixture. An in tank state quantity estimation device 111 comprises: a temperature acquisition part 112 for acquiring a temperature Tt in the tank 70; a pressure acquisition part 112 for acquiring a pressure Pt in the tank 70; a gas refrigerant partial pressure calculation part 113; a non-condensable gas partial pressure calculation part 114; and a non-condensable gas mass calculation part 115. The gas refrigerant partial pressure calculation part 113 obtains the gas refrigerant partial pressure corresponding to the temperature Tt in the tank 70. The non-condensable gas partial pressure calculation part 114 obtains the non-condensable gas partial pressure from the pressure Pt in the tank 70 and the gas refrigerant partial pressure. The non-condensable gas mass calculation part 115 obtains the non-condensable gas mass using a gas state equation.SELECTED DRAWING: Figure 1
