A salt water desalinating system having a water providing device for allowing vapor to be absorbed into concentrated salt water and a concentrated salt water desalinating device for the concentrated salt water; and a salt water desalinating method having an absorbing process for allowing water to be absorbed into concentrated salt water and a concentrated salt water desalinating process for the concentrated salt water. The water providing device has a plurality of absorption heat pumps arranged in series, for allowing water evaporated from dilute salt water to be absorbed into the concentrated salt water. The concentrated salt water circulates between the water providing device and the concentrated salt water desalinating device. Since no salts move between the concentrated salt water and the dilute salt water, a salt water desalinating system free from scales is provided.
