Keywords:Energy, Desalination, Compressor, Aquadest, Cyclone Separator, Refrigerant, Throttling
The problem of freshwater is an issue that has been hot for discussion for decades. The number of industries and the increasing population in the world has caused the need for clean water to increase drastically. This scarcity occurs because 97.7% of the water available on earth contains salt. Only 2.3% contains no salt, and 99.5% of the amount is ice, groundwater, and the atmosphere. With a large percentage of seawater, water needs for human survival can be met by using the desalination method. In this study using a throttling valve and utilizing cold water (secondary product) as a refrigerant to cool the room. This research will also discuss how specific energy consumption and cooling heat are affected by compressor pressure and cyclone pressure to prove how capable and efficient the renewable desalination method is in producing aquadest water, which is expected to help water availability to meet water needs. The simulation results obtained The optimum value of the system specific energy consumption is 287.90 kJ / kg with a compressor pressure value of 10 kPa and a cyclone temperature value of 4 ° C. The optimal value of system cooling heat is 51.01 kW with a compressor pressure value. At 10 kPa and a cyclone temperature value of 2 ° C. The effect of the cooling heat value significantly affects the specific energy consumption required for this system.
