PROBLEM TO BE SOLVED: To provide a refrigerating cycle device capable of preventing dew condensation of a liquid pipe more easily in comparison with large-scale construction such as applying thermal insulation treatment to the liquid pipe, when adding supercooling to the liquid pipe of the refrigerating cycle device to increase its cooling capacity. SOLUTION: The refrigerating cycle device is provided with a first coolant circulation circuit connecting a first compressor 1, a first condenser 2, a first expansion valve 3 and a first evaporator 4 in order. It is provided with a cooling device 5 cooling a liquid coolant flowing from the first condenser 2 to the first expansion valve 3, a liquid pipe temperature sensor 6 detecting a temperature of the liquid pipe 15 sending the coolant cooled by the cooling device 5 to the first expansion valve 3, an ambient temperature sensor 7 detecting an ambient temperature of the liquid pipe 15, and a controller 8 controlling a cooling rate of the cooling device 5 on the basis of each detected value of the liquid pipe temperature sensor 6 and the ambient temperature sensor 7.
