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

Abstract

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