PROBLEM TO BE SOLVED: To achieve both an improvement in efficiency of a compression type refrigerating device and reduction in the initial cost and running cost of a whole refrigerating system by controlling refrigerating capacity of the absorption type refrigerating device by corresponding to a change in an operating condition on the compression type refrigerating device side in an absorption type refrigerating device driven by exhaust heat of an engine that drives the compression type refrigerating device. SOLUTION: When a cooled fluid temperature at an outlet of an evaporator becomes a target temperature or less calculated based on an outside temperature and a condensation temperature of the compression type refrigerating device X, control is performed for decreasing refrigerant absorbing capacity of an absorber 4, and at the same time, refrigerating capacity of the absorption type refrigerating device Z is reduced by stopping a refrigerant pump 13 or reducing a circulating refrigerating flow rate. Further, when the temperature becomes the target temperature or higher, the refrigerant absorbing capacity of the absorber 4 is decreased, and at the same time, the refrigerating capacity of the absorption type refrigerating device Z is increased by operating the refrigerant pump 13 or increasing the circulating refrigerant flow rate.
