The paper evaluates the EW-1000 Atmospheric Water Generation-Vapor Compression Refrigeration system (AWG-VCRS) as a sustainable alternative to seawater desalination in the GCC. Conducted in Masdar City, Abu Dhabi, from July 2023 to January 2024, the study measured temperature, humidity, energy consumption, and water production. Key findings include a peak water production of 1500 LPD in September and an average Specific Energy Consumption (SEC) of 0.26 kWh/L. Productivity decreased by 71 % in cooler, dryer months. With a coefficient of performance (COP) of 3.6, the system aligns with conventional air conditioners, highlighting its potential for enhancing water security in arid regions.
