A Novel Ambiently Adaptive Atmospheric Water Generator Using Maximum Production Tracking Algorithm

Abstract

In this paper, a Thermo-Electric Cooler (TEC) based ambiently adaptive Atmospheric Water Generator (AWG) system is proposed. Due to the advantages of TEC technology, it has been relied upon in the phase of dehumidifying the air flowing in the proposed system as an alternative to other mechanical methods. An AWG cooling control system has been developed based on the proposed algorithm to determine the temperature that achieves the highest productivity, which depends on the change in thermal load by changing the airflow, which keeps the temperature of the humid air inside the system below the Dew Point (DP) temperature at varying ambient conditions for sustainable water productivity. A novel Maximum Production Tracking (MPT) algorithm is introduced to automatically determine the marginal temperature below the DP for maximum productivity. The proposed system is simulated using MATLAB/SIMULINK under different ambient conditions. The obtained results affirmed the potential and verification of the proposed approach.
