Atmospheric Water Harvester with Cryogenic System
An atmospheric water harvesting system includes a water-harvesting unit with an air mover and a heat exchanger. The water-harvesting unit may also include one or more screens on which water can condense. The water-harvesting unit is supplied by a coolant pathway, in which a non-cryogenic fluid coolant flows. A cryogenic cell is in the coolant pathway. The cryogenic cell receives the fluid coolant and removes heat from it by causing or allowing a controlled heat transfer between the fluid coolant and a first cryogen sealed within an inner vessel in the cryogenic cell. The coolant may be a liquid at operating temperatures, and the cryogenic cell may cool it to an appropriate temperature without a phase change, essentially acting as a “cold battery” to remove heat from the coolant.
