摘要： PROBLEM TO BE SOLVED: To sufficiently utilize the capability of an exhaust heat utilization apparatus in an exhaust heat utilization system which recovers exhaust heat from a plurality of heat source with varies calorific values depending on operational situation.
SOLUTION: The passage of warm water discharged from blades 21a-21d is changed over by a thermosensitive self-operated changeover valves 32a-32d. Warm water of prescribed temperature or more is fed to an absorption type refrigerator 60, and warm water lower than the prescribed temperature is fed to a cooling water reservoir tank 30. The absorption type refrigerator 60 uses the warm water to regenerate desiccant. When the flow rate of warm water fed to the absorption type refrigerator 60 is insufficient, warm water heated by an auxiliary heat source 34 is fed to the absorption type refrigerator 60.
