Résumé

This paper presents a novel LiBr/H2O absorption cooling and desalination system with three pressure levels which uses seawater as a cooling medium and is activated by solar thermal energy. This system helps counteract coastal populations’ thermal conditioning and water supply problems. In order to show technical feasibility, Aspen Plus was used to simulate the system with the following parameters: a 23?kW cooling capacity; different seawater temperatures; and, a concentration of 35,000?ppm. It was found that the proposed technology has 19.4% more efficiency than a conventional single-effect absorption cooling system, with an FR of 0.08 and an R of 1.84, and produces 838 additional L/day of water, enough to satisfy the requirements of a household for up to 7 people. With the configuration of the proposed technology, which manages three levels of pressure, and using seawater as a cooling medium, the simultaneous production of cooling and desalination is benefited.
