Influence of the Rate of Induced Electrical Energy as a Source of Heat Energy on the Productivity of Converting Seawater into Freshwater

One of the significant problems to be solved is the availability of clean water for public consumption. As the population increases, the clean water needs will also increase. Some areas are at risk of shortages of clean water. One of them is in coastal areas. One of the methods used is to convert seawater into freshwater to provide clean water in coastal areas. With the distillation process, water can be separated from salt. In this research, the heat source used is induction electrical energy. The induction heater is chosen because of its efficiency. A method to change seawater into pure water is to boil the seawater. In this research, the level of electricity power is 600 W, 800 W and 1000 W. The airspeed over the condenser was varied in three level of speed. The result shows that the highest freshwater product is at 1000 W at level 1 airspeed with freshwater product is 632 grams. The most effective result is at 900 W induction heater with power consumption of 1.295 W/g.
