摘要： PROBLEM TO BE SOLVED: To obtain an effect of improving performance both in cooling operation and heating operation in a refrigerating device formed of a combination of a vapor compression type refrigerating machine and an absorption type refrigerating machine. SOLUTION: This refrigerating device with the vapor compression type refrigerating machine X and the absorption type refrigerating machine Y includes a heat recovery heat exchanger 6 performing heat exchange between the refrigerant of the vapor compression type refrigerating machine X and the solution on the outlet side of the absorber 12 of the absorption type refrigerating machine Y. During cooling operation of the vapor compression type refrigerating machine X, refrigerant heat on the vapor compression type refrigerating machine X side is recovered to the solution side of the absorption type refrigerating machine Y in the heat recovery heat exchanger 6, and the refrigerant is supercooled in the evaporator 13 of the absorption type refrigerating machine Y to lower the evaporation temperature. During heating operation of the vapor compression type refrigerating machine X, the temperature of the refrigerant of the vapor compression type refrigerating machine X is raised by heat exchange in the heat recovery heat exchanger 6, thereby increasing the heat radiation amount resulting from condensation of the refrigerant. As a result, the effect of improving the performance of the vapor compression type refrigerating machine X can be obtained both in the cooling operation and heating operation.
