ABSTRACT:
A refrigerant recovering sealed container has at least a refrigerant passing portion. A connecting portion connects the refrigerant passing portion of the refrigerant recovering sealed container to a refrigerant supply/discharge port of an existing refrigeration cycle unit. A cooling section cools the interior of the refrigerant recovering sealed container so that a refrigerant filled in the existing refrigeration cycle unit is introduced into the refrigerant recovering sealed container through the connecting portion as a gaseous refrigerant and is recovered as a liquefied refrigerant. A measuring section measures an amount of the refrigerant recovered in the refrigerant recovering sealed container as the liquefied refrigerant by the cooling section. A control unit supplies control signals for activating the connecting portion, the cooling section, and the measuring section in a predetermined order.
