| Abstract | ||
| Adsorption desalination technology has gotten a lot of attention in the recent decade. It can be powered by waste heat sources, which means it uses less energy and emits less CO2. This research investigates a two-bed silica-gel/water-based system. The conservation of energy/momentum equations of the current system are modeled using MATLAB SIMULINK software, as a result of which the energy balance equations for the adsorber bed, condenser, and evaporator were solved. The study is carried out with the investigation of many key parameters like heat source, condenser, evaporator temperatures and half-cycle time to find their effect on the SPECIFIC DAILY WATER PRODUCTION (SDWP) and SPECIFIC COOLING POWER (SCP) generated from the system. The simulation model used in this paper was verified using previously published experimental research. The results show that the maximum (SDWP) generated from the system is (19.3221 l/kgads/day) and (SCP) is (493.183 W/kgads). A comparison was made to the current research with previously published research, and promising results were obtained. | ||
