PROBLEM TO BE SOLVED: To recover a refrigerating machine oil of an evaporator while increasing a refrigerant flow rate in a bypass operation in heating motion and the like.SOLUTION: This refrigerating device (10) for the container, includes a refrigerant circuit (20) having a hot gas bypass circuit (22) and executing a refrigeration cycle, and executes the bypass operation to allow a compressed refrigerant of a compressor (30) to pass through the bypass circuit (22) and flow into the evaporator (33). The refrigerating device further includes a refrigerant amount adjustment part (107) that can execute a refrigerant flowing-in motion for allowing a part of the compressed refrigerant of the compressor (30) to flow into a high-pressure liquid pipe (25) including a condenser (31), and a refrigerant replenishment motion for allowing the refrigerant of the high-pressure liquid pipe (25) to flow into the evaporator (33) after the refrigerant flowing-in motion. |
