Study of the impact of variable-phase materials (PCM) on the single basin two-slop solar distiller

The potable water declined after the global climate crisis. Due to warming. River levels have also decreased. Moreover, so much has become dependent on from wells. Which are often salty. Purifying this requires many fossil fuels that cause damage environment. Therefore, researchers turned renewable energy sources, including solar energy. In paper, we designed and made a distiller, single sink with double slope. It is used desalinate remove salt using This technique best solution for obtaining in remote desert areas where not available. purpose of research study variables promote increased efficiency. Study use phase change materials (PCM) enhance productivity distillers. Bitumen was store thermal latent heat. efficiency by (15–25%). For distiller bitumen basin relative which it added.
