Benchmarking Dehumidifiers as Atmospheric Water Generators in Tempe, AZ
Mentor: Sergi Garcias Segura
The goal was to benchmark the performance and quality of water collected from the air using common household dehumidifiers as atmospheric water generators. It is found that for between $13 and $20 a day, 12 to 19 gallons of clean water can be produced in a device that fits within a single square meter. Envisioned applications include water recovery for disaster relief, military scenarios, and for rural citizens with distant water sources. Future work involves a prototype, which would benefit greatly from advanced solar panels, improved desiccation technologies, and improved filtration medium.
Pressure Differential Sequestration of Ambient Humidity
Mentor: Paul Westerhoff, Sergi Garcias Segura
The research goal is to gauge the effectiveness of collecting water by pressurizing air. The researcher has completed modelling using realistic environmental data. It was found that more than 3 liters per day could be produced in a square meter area using 31 atmospheres of pressure. This idea was presented to faculty researchers for discussion and input was given, which was a valuable learning experience. A prototype is in progress with an envisioned application in water recovery for disaster relief and military scenarios.
