PROBLEM TO BE SOLVED: To provide an exhaust heat recovery system capable of improving an energy utilization rate of a cooling system, an exhaust heat recovery method and the cooling system.SOLUTION: In one embodiment, an exhaust heat recovery system recovers exhaust heat of an absorption type or adsorption type refrigeration machine including: a cooling section for cooling fluid to be cooled; a heat absorbing section for absorbing heat of first heat source fluid or absorbing heat of second heat source fluid heated by using the heat of the first heat source fluid; and a heat radiating section for radiating heat received from the fluid to be cooled and the heat absorbed by the heat absorbing section. The exhaust heat recovery system includes: a water flow passage that supplies water to the heat radiating section, radiates the heat received from the fluid to be cooled and the heat absorbed by the heat absorbing section to the water in the heat radiating section and conveys the water with a first temperature that has been discharged from the heat radiating section; and a heater for heating the water from the water flow passage by using the first or second heat source fluid and producing the water with a second temperature to be used as hot water.SELECTED DRAWING: Figure 1 【課題】冷却システムのエネルギ利用率を向上させる事が可能な排熱回収システム、排熱回収方法、及び冷却システムを提供する。【解決手段】一の実施形態によれば、排熱回収システムは、被冷却流体を冷却する冷却部と、第１熱源流体の熱を吸熱する、または、前記第１熱源流体の熱により加熱された第２熱源流体の熱を吸熱する吸熱部と、前記被冷却流体から受けた熱と前記吸熱部により吸熱された熱とを放熱する放熱部と、を具備する吸収式または吸着式の冷凍機の排熱を回収する。前記排熱回収システムは、前記放熱部に水を供給し、前記被冷却流体から受けた熱と前記吸熱部により吸熱された熱とを前記放熱部内で前記水へと放熱し、前記放熱部から排出された第１温度の前記水を搬送する水流路と、前記水流路からの前記水を前記第１または第２熱源流体を用いて加熱して、温水として使用される第２温度の前記水を製造する加熱器とを具備する。【選択図】図１
