We present a new type of sorbent material involving an aluminum heat exchanger coated with a hydrophilic alginate biopolymer hydrogel for atmospheric water harvesting (AWH). The hydrogel-coated heat exchanger is tested in a prototype driving cycle, collecting water over several days of continuous operation. The thermal cycle performance of the coating is tested in dry climates with relative humidity in the range of 30–50%. The new sorbent demonstrates regeneration temperatures between 60 and 80 °C, allowing efficient thermal cycles. The system allowed for a water yield of 2.48–3.3 L/kgHydrogel/day. The compactness of the coated heat exchanger, together with the performed daily water productivity, makes it compatible with applications integrating AWH technologies in the building sector.
Hydrogel-coated heat exchanger maximizes water production, transforming atmospheric water harvesting for the building sector’s needs and demands. Atmospheric water harvesting device made with hydrogel coating on an aluminum heat exchanger and its corresponding scanning electron microscopy image.
