METHOD AND SYSTEM FOR PRODUCING DRINKING WATER FROM AIR

An apparatus and methods for extracting water from air with desiccants is disclosed. In some embodiments, the apparatus includes a reactor (i) for flowing hot dry air through a water saturated desiccant to desorb water therefrom into the hot dry air to obtain humidified hot air or (ii) for flowing an external airflow through the desiccant to obtain the water saturated desiccant. The first heat exchanger transfers heat from the humidified hot air to the cold dry air to obtain humidified cool air and warm dry air. The second heat exchanger removes excess heat from the humidified cool air toward outside of the apparatus to cool the humidified cool air, to obtain water and cold dry air. The heater produces hot dry air for flowing through the water saturated desiccant. The flow paths of hot dry air, humidified hot air, humidified cool air, and cold dry air are in a closed-loop.
