태양열 및 폐열을 이용한 흡착식 담수화 시스템의 기초연구

According to the recent UN environmental report, Korea was classified as one of the countries with the shortage in potable water supply. Approximately 71% of the Earth's surface is covered by ocean. It is, however, difficult to harness natural water directly for industry or residential purposes without any purification or treatment processes. As a viable option in utilizing clean energy, this study has examined the development of absorption desalination technology in link with exploiting solar thermal energy and waste-heat. Major components of a adsorption desalination system was designed and analyzed, which was further developed to build a one-bed(reactor) adsorption desalination plant employing low-temperature solar energy and waste heat. A series of measurements were made to assess its performance and elicit the most feasible and efficient model. Especially, the amount of fresh water yield was cautiously monitored with respect to the time controlling parameters such as heat source temperatures, coolant temperatures, system switching and half-cycle operation times.
