    Abstract: A new approach for desalination and purification of sea water using refrigeration units is suggested which seems promising to provide high quantities of drinkable water with reasonable cost. The apparatus uses compression refrigeration system to provide heat at the condenser to partially evaporate the intake sea water and uses evaporator at the other side to condense the produced water vapor back to clean drinkable water. A heat recovery heat exchanger captures the heat left in the returning sea water and delivers it to the fresh intake sea water to improve the efficiency and performance. The system can be designed using different refrigerants with some providing higher efficiencies and coefficients of performance. A typical desalination system using this approach shows in theory a production of about 3.6 trillion gallons of potable/drinkable water per year with only about 100 MW electric power installed. Equivalent electrical energy (kWh/m3) consumed by different methods has been reported about 13.5-25.
