The fresh water stored here is widely used for drinking water, agricultural water (plant cultivation), etc. In addition, in the case of cloudy weather, evening, etc., sunlight decreases, so some of the steam in the evaporation chamber 18 may condense on the back surface of the evaporation heat exchanger 9 and become fresh water. In this case, it is captured by the fresh water gutter 29 and stored in the fresh water tank in the same manner as above.

The structure is such that the above-mentioned return water is temporarily retained. According to this, when a part of the return water held in the recess evaporates into the outside air, latent heat is taken away, so the temperature of the return water approaches the outside air wet bulb temperature, that is, it is cooled and reused. Return to cold water tank 3. Therefore, if this is repeated, the temperature of the cold water tank 3 will automatically drop.

Since the temperature of the cold water tank 3 is automatically lowered, the heat exchange efficiency of the evaporation heat exchanger 9 and the condensation heat exchanger 25 is improved. Therefore, the amount of evaporation in the evaporation chamber 18 increases, and the amount of condensation on the back surface of the condensing heat exchanger 25 increases, so compared to the conventional one, the amount of fresh water per unit area of the heat exchangers 9, 25 increases. The amount of chemical water production can be significantly increased.

Since the salt content in the cold water tank 3 and the hot water tank 5 gradually increases, it is necessary to replace the seawater in each tank 3 and 5 periodically. In such a case, a salinity detection sensor is placed in each tank 3 and 5, and a solenoid valve is installed in the seawater introduction and discharge pipes, and the solenoid valve is opened and closed by the signal from the sensor to remove the seawater.
