Abstract

 This study aims to propose a method for the thermal recovery of regenerated bed in a two-bed Adsorption Desalination system. It investigates the affection of thermal recovery, heating water temperature, and cooling water temperature entering the bed and condenser on the performance of the system. The analysis demonstrated that at a constant temperature of cooling water, the amount of water that is produced increases by raising the temperature of hot water and the energy consumption does not change significantly. For example, at a cooling water temperature of 20 ° C, by increasing the temperature of heating water from 50 to 90 ° C, the water that is produced is 3. 75 times more and the energy consumption is reduced by 7. 4 %. Heat Recovery reduces the energy consumption of the system. As the temperature of the hot water increases, the effect of thermal recovery increases. As a result of Heat Recovery at a heating water temperature of 50 and 90 ° C, the energy consumption of the system decreases by 10. 9 % and 37. 6 %, respectively. Increasing the temperature of the inlet cooling water to the bed and the condenser reduces the production of water and increases the energy consumption of the system. The effect of the temperature of cooling water entering the condenser on the water that is produced and the energy consumption is greater than that of the cooling water entering the bed. As the cooling water temperature increases, the energy-saving as a result of thermal recovery decreases. For example, At a cooling water temperature of 10 ° C, thermal recovery reduces the energy consumption of the system by about 47 %, while at 23° C it is about 12 %. Again the effect of cooling water temperature that enters the condenser is more than that enters the bed. By increasing the temperature of cooling water entering the condenser from 15 to 35° C, energy savings due to the Heat Recovery reduces from 53. 7 to 9. 3 %.
