PROBLEM TO BE SOLVED: To provide a refrigerating device capable of preventing refrigerator oil from remaining in an evaporator in a large amount having adverse affect on cooling performance, at reduced running cost. SOLUTION: The refrigerating device 1 has a circulating fluid passage 8 which communicates with a suction opening 2b of a compressor 2 from a discharge opening 2a of the compressor 2 to constitute a refrigerating cycle, with an oil separator 3, a condenser 4, a liquid receiver 5, an expansion valve 6, and an evaporator 7 mounted in the fluid circulation passage 8 in that order. A discharge port 7a through which to discharge the internal liquid is provided in the shell of the evaporator 7 and communicated with the circulating fluid passage 8 via a liquid return line 10 in which a flow control valve 11, a flowmeter 12, and a selector valve 13 are inserted, to return the liquid in the evaporator 7 to the compressor 2.
