PROBLEM TO BE SOLVED: To provide a fresh water generation system capable of securing a heat quantity for obtaining a sufficient quantity of plain water even in the case where a temperature of jacket cooling water to be drained from an internal combustion engine falls.SOLUTION: A fresh water generation system 1 comprises: a fresh water generation device 2 including a heater 3; a first cooling water flow passage 7 in which exhaust air cooling water is circulated; a second cooling water flow passage 8 in which jacket cooling water is circulated; a first circulation path 9; and a second circulation path 10. The fresh water generation system is configured to guide cooling water flowing in the first circulation path 9 or cooling water flowing in the second circulation path 10 to the heater 3 and to exchange heat with seawater. In the circulation path 9 where the cooling water to be guided to the heater 3 flows, at an upstream side of the heater 3, a heat exchanger 16 is provided for exchanging heat between the cooling water flowing in the circulation path 9 and the cooling water flowing in the other circulation path 10. In the other circulation path 10, at an upstream side of the heat exchanger 16, a flow regulating valve 23 is provided for regulating a flow rate of the cooling water to be guided to the heat exchanger 16.SELECTED DRAWING: Figure 1
