To provide a refrigerating device capable of being stably operated for a long period by removing hydrogen fluoride generated in a refrigerating cycle, and suppressing deterioration of components used in the refrigerating cycle.
This refrigerating device in which a refrigerant prepared by mixing hydrofluoroolefin having carbon-carbon double bond as a base component with hydrofluorocarbon not having the double bond, is circulated, has a refrigerant circulating passage for circulating the refrigerant from a compressor 1 to the compressor 1 through a condenser 2 or 4, an expanding mechanism 3 and an evaporator 4 or 2, and a hydrogen fluoride capturing section 8 disposed in the refrigerant circulating passage to receive the hydrogen fluoride capture agent.
