Title: PURGING DEVICE, REFRIGERATOR EQUIPPED WITH SAME, AND METHOD FOR CONTROLLING PURGING DEVICE
Abstract:
A purging device equipped with: a purging pipe (17) for purging a gas mixture containing a coolant and a non-condensable gas from a refrigerator; a purging tank (40) for storing the gas mixture purged from the purging pipe (17); a cooling device (42) which cools the interior of the purging tank (40) and condenses the coolant in the gas mixture; a drainage pipe (19) for discharging the liquid coolant inside the purging tank (40) to the refrigerator; an exhaust pipe (50) for discharging the non-condensable gas in the gas mixture inside the purging tank (40) to the exterior; and a control unit (16) which stops operation of the purging device (15) when the discharged non-condensable gas amount discharged from the exhaust pipe (50) exceeds the introduced non-condensable gas amount introduced into the refrigerator.
