Abstract: Atmospheric water harvesting technologies can be classified based on working principles, namely condensation technology, sorption technology and other technologies. Condensation technology utilizes various refrigeration technologies such as vapor compression cycle, thermoelectric cooling and adsorption/absorption cooling for condensing water vapor. Water harvesting processes can be operated as long as electricity is available. For other technologies, it can be further divided into innovative technologies and hybrid technologies. For innovative technologies, renewable energy powered VCC systems, solar chimney and geothermal cooling systems are used. Based on the above three categories, This paper summarizes these water harvesting technologies from perspectives of system configurations, test setups, simulation methods, performances analysis and important findings. Based on current review study, performances and research gaps of these technologies are compared and evaluated, and possible future research for atmospheric water harvesting in humid or dry climate regions are proposed.
