A salt water desalinating device, characterized by having an absorption refrigerating machine using a first dilute salt water and concentrated salt water and characterized in that a second dilute salt water to be desalinated is evaporated by heat flowing out from the high-temperature heat source of the absorption refrigerating machine and vapor evaporated from the second dilute salt water is condensed by heat to be absorbed to a refrigeration source. A plurality of the absorption refrigerating machines may be series-connected in a series arrangement. A method of desalinating salt water comprising the steps of supplying a first dilute salt water to a refrigeration source, supplying concentrated salt water to a high-temperature heat source, discharging the first dilute salt water having a high concentration after water evaporation, discharging the concentrated salt having a low concentration after water absorption, discharging the second dilute salt water having a high concentration after water evaporation and recovering condensed fresh water.
