To simplify the configuration of a generator of an absorption refrigerator and to improve the refrigeration performance of a vapor compression refrigerator in a refrigerating device wherein the vapor compression refrigerator and the absorption refrigerator are combined and the absorption refrigerator is driven by the exhaust heat of the vapor compression refrigerator.

The refrigerating device includes a vapor compression refrigerator and an absorption refrigerator driven by the exhaust heat of the vapor compression refrigerator. A heat exchanger for collecting refrigerant heat is provided which collects the heat of refrigerant after compression of the vapor compression refrigerator by means of a dilute absorbed solution of the absorption refrigerator. The heat exchanger causes the dilute absorbed solution to flow into a generator of the absorption refrigerator after the solution has collected the heat of the compressed refrigerant, and refrigerant vapor is separated whereby the generator of the absorption refrigerator is used as a gas-liquid separator serving only to separate the refrigerant vapor from the dilute absorbed solution flowing in, and the compressed refrigerant of the vapor compression refrigerator is cooled or supercooled to improve the refrigeration performance of the vapor compression refrigerator.
