N2 - According to forecasts, analysts estimate the coming decades of freshwater will be one of the rarest resources in the world, and many countries will consume water that has been desalinated. This scarcity will occur continually, although 1/3 earth is water, but 97.7% of the water available on earth contains salt. Only 2.3% of the remainder do not contain salt, and 99.5% of the amount is ice, groundwater, and atmosphere. With desalination method, the level of water requirements for human survival can be fulfilled by utilizing a large percentage of seawater amount. In this study, the desalination method used was a thermodynamic simulation method by adopting the secondary product or cold water as refrigerant of the air conditioner (AC) that was applied to control the room. In this study will also discuss on how temperature affects the heat exchanger 1 and cyclone pressure against specific energy consumption (SEC) and cooling heat. Then we can prove how efficient the method of renewable desalination in producing aquadest water that was expected to help water availability to meet the needs of water. Briefly, the optimum value of the system's specific energy consumption is 287.90 kJ/kg with the outlet temperature of the heat exchanger 1 value of 90°C and a cyclone temperature value of 4°C. The optimum value of the cooling heat of the system is 51.01 kW with the outlet temperature of the heat exchanger 1 value of 90°C and the temperature value of cyclone of 2°C. The effect of cooling heat values significantly affects the specific energy consumption required for this system.
