Abstract
The invention is a water generator device from air utilizing solar thermal energy and adsorption principle. The system is based on an adsorption refrigeration unit with Ether as a refrigerant and activated carbon as adsorbed. The required heat is generated from evacuated tube solar system and the heat sink is the atmosphere. The adsorption unit is an air-cooled refrigeration unit that can operate at relatively low hot water temperature (60-70.degree. C.) and relatively high atmospheric temperature (30-40.degree. C.). The water condensed from air is than driven through a simple water purification unit to assure its quality as drinking water. The very small electricity needed to operate the hot water and cold water pumps along with the filtration unit and the controller of the adsorption unit is generated from a small Photo Voltaic (PV) unit for stand alone systems.
