This work shows a technical review for two promising technologies and two commercial systems that can be applied in Hybrid Wind Systems —also known as Extraction Water from Air Systems (EWAS) — for the special weather conditions presents in Brazilian northeast. Additionally, a full description of the main components for the innovative technologies and for commercial solutions are explained. An energy consumption analysis for each one of these systems is made for comparison purposes. Water extraction capacity and energy efficiency are evaluated (for two commercial EWAS) for a theoretical operation point in the middle of the North–eastern semi–desert region. This point is obtained by means of the well–known humid air diagram. Important information about minimum environmental conditions for Membranes and Coils are also considered. Three main types of electric generators are described, including its advantages and disadvantages, for the estimation of the power ratio to generating electricity and water. For all above, the right sizing of the future Brazilian EWAS prototype and its possible application in a semi-arid region is the objective of this paper.

从潮湿空气中提取饮用水和风力发电：巴西原型的可能应用

这项工作展示了对两种有前途的技术和两种商业系统的技术审查，这些技术和两种商业系统可应用于混合风系统——也称为从空气系统中提取水 (EWAS)——以应对巴西东北部的特殊天气条件。此外，还解释了创新技术和商业解决方案的主要组件的完整描述。为比较目的，对这些系统中的每一个都进行了能耗分析。针对东北半沙漠地区中部的理论操作点，评估了水提取能力和能源效率（针对两个商业 EWAS）。这一点是通过著名的湿空气图获得的。还考虑了有关膜和线圈的最低环境条件的重要信息。描述了三种主要类型的发电机，包括其优点和缺点，用于估计发电和水的功率比。综上所述，未来巴西 EWAS 原型的正确尺寸及其在半干旱地区的可能应用是本文的目标。
