Abstract
A device for obtaining water from air on an island includes: a concentrated solution air water obtaining system, a solar collector, a dilute solution dehydration system, a heat pump system, a solution heating system, and a water purification system. Humid air is introduced into the concentrated solution air water obtaining system, which performs a heat and mass transfer into a dilute solution and relatively low-temperature dry air. This air is used as interior fresh air. The diluted solution is heated by the solar collector, delivered to the dilute solution dehydration system, and sent to the solution heating system for heating and evaporating into water vapor. The water purification system cools, purifies, filters and stores the water vapor. At the same time, the heat pump system introduces heated humid air into the dilute solution dehydration system to recover heat contained in the heated humid air, and to extract water.
