摘要

大气集水（AWH）已成为缓解全球重大水资源问题的一项重要技术。吸附式大气集水（SAWH）的进展主要集中在新型材料上，往往忽略了系统层面的考虑。我们介绍了首款紧凑型快速循环燃料燃烧（CRCF）AWH 设备。CRCF 设备将富马酸铝 MOF 装入紧凑型吸附热交换器 (AHX)，使用燃料燃烧和环境冷却冷凝器。CRCF 原型旨在最大限度地提高容积生产密度（PvPv），即 AHX 单位体积的日产水量（kgwater(m3)AHX-1day-1kgwater(m3)AHX-1day-1）。与纯太阳能驱动的系统相比，燃料可实现每日连续循环，并减少系统占地面积。计算模型用于优化吸附截断和吸附剂鳍片厚度（τ），以获得最大的水生产率（P）或 PvPv，这证明了 CRCF 的潜力。与最先进的基于金属有机框架的多循环无制冷 SAWH 设备相比，CRCF 的日水生产率可达到 3.19 kgwaterkgMOF-1day-1kgwaterkgMOF-1day-1，PvPv 可达到 718（kgwater(m3)AHX-1day-1kgwater(m3)AHX-1day-1），P 和 PvPv 分别提高了 1.5 倍和 2.1 倍。

Compact rapid cycling fuel-fired atmospheric water harvesting device for all-day water production

Atmospheric water harvesting (AWH) has emerged as a vital technology in alleviating the significant water struggles around the globe. Advances in sorption-based AWH (SAWH) primarily focus on novel materials, often overlooking system-level considerations. We introduce the first-of-its-kind compact rapid cycling fuel-fired (CRCF) AWH device. The CRCF device packages aluminum fumarate MOF into a compact adsorbent heat exchanger (AHX), which uses fuel combustion and an ambiently cooled condenser. The CRCF prototype was designed to maximize volumetric production density ( $P_{v}$ $P_{v}$ ), defined as the daily water production per unit volume of the AHX ( $k g_{w a t e r} {(m^{3})}_{A H X}^{- 1} d a y^{- 1}$ $k g_{w a t e r} {(m^{3})}_{A H X}^{- 1} d a y^{- 1}$ ). Fuel enables continuous daily cycling and reduces the system footprint relative to a purely solar-driven system. A computational model is used to optimize the adsorption truncation and the thickness of sorbent fins (τ) for maximum water productivity (P) or $P_{v}$ $P_{v}$ demonstrating the potential of CRCF. A daily water productivity of 3.19 $k g_{w a t e r} k g_{M O F}^{- 1} d a y^{- 1}$ $k g_{w a t e r} k g_{M O F}^{- 1} d a y^{- 1}$ or a $P_{v}$ $P_{v}$ of 718 ( $k g_{w a t e r} {(m^{3})}_{A H X}^{- 1} d a y^{- 1}$ $k g_{w a t e r} {(m^{3})}_{A H X}^{- 1} d a y^{- 1}$ ) can be achieved representing an improvement of 1.5× and 2.1× in P and $P_{v}$ $P_{v}$ relative to state-of-the-art metal organic framework-based multi-cycle SAWH devices operating without refrigeration.
