大气中的水资源利用：雾和露水可持续集水方法综述

Utilization of Water Resources in the Atmosphere: A Review of Methods for Continuously Collecting Water from Mist and Dew

摘要: 本文综述了大气中的雾和露水可持续集水方法。首先，介绍了全球范围内各种类型的集雾器及其集水性能，并对一些可行性研究和效率改进的技术进行了回顾，其中包括以生物为灵感的现代创新技术。但是，由于全球雾发生的限制，雾收集技术在实际应用中存在困难。相比之下，露水采集器虽然需要冷却冷凝表面，但更为普遍使用。最后，将露水收集系统分为三类：1) 使用辐射冷却表面收集露水，2) 太阳能干燥剂系统，3) 主动冷凝技术。所有这些方法的关键目标是开发一种成本低廉、可以利用当地材料制造、无论湿度水平或地理位置如何，都能产生水的大气集水器。

Abstract: This article reviews the sustainable water collection methods of fog and dew in the atmosphere. Firstly, various types of mist collectors and their water collection performance worldwide were introduced, and some feasibility studies and efficiency improvement technologies were reviewed, including modern innovative technologies inspired by biology. However, due to the limitations of global fog occurrence, there are difficulties in the practical application of fog collection technology. In contrast, dew collectors, although required to cool the condensing surface, are more commonly used. Finally, dew collection systems are divided into three categories: 1) dew collection using radiative cooling surfaces, 2) solar desiccant systems, and 3) active condensation technology. The key goal of all these methods is to develop a low-cost atmospheric water collector that can be manufactured using local materials and generate water regardless of humidity levels or geo-graphical location.
