Thermodynamic analysis and improvement of a novel solar driven atmospheric water generator

In this study, an improved novel solar driven atmospheric water generator device has been proposed to generate more water with less power usage. The system consisting of three parts: solar driven ammonia absorption refrigeration cycle, saline water desalination cycle and air dehumidification cycle. The system generates water from two great water sources simultaneously with equal power input to common AWG (Atmospheric Water Generator). Thermodynamic analysis of system has been done by parametric analysis of sub series cycles. The device performance curves have been introduced according to results. These curves can be used to determine the water generation of the improved novel AWG device in every place (or City) with having air relative humidity, and temperature of desired location. The performance of improved novel AWG device was analyzed in four cities of Iran. AWG water generation rate in case cities improved averagely about 165% by improvement process.
