项目摘要

Commercial and residential air-conditioning systems consume a significant fraction of the world's power output in order to keep people cool and comfortable. Much of this power usage goes to cooling and condensing the water vapour in humid air. It has been projected that removing this water by a process known as membrane-based dehumidification can cut this power consumption in half. However, current membranes do not perform well enough to allow for economical installations of such systems. In order to bring this technology to fruition, Evercloak, in collaboration with the University of Waterloo, aim to significantly improve membrane performance through the development of ultra-thin, water-selective membranes based on graphene oxide. The proposed project aims to identify failure modes and develop unique interlayers to stabilize the ultra-thin membranes using methods compatible with Evercloak's roll-to-roll nano-film printing technology. The project outcomes are expected to improve upon Everlcoak's current membrane technology which will allow them to penetrate the market faster. The success of this project will bring membrane-based dehumidification to reality and enable more efficient cooling as well as industrial dehumidication/dehydration technologies which are expected to significantly reduce society's environmental footprint.

商业和住宅空调系统消耗了世界电力输出的很大一部分，以保持人们凉爽和舒适。大部分电力消耗都用于冷却和冷凝潮湿空气中的水蒸气。据预测，通过一种被称为膜基脱硫的工艺去除这些水可以将这种电力消耗减少一半。然而，目前的膜的性能不足以允许经济地安装这种系统。为了实现这项技术，Evercloak与滑铁卢大学合作，旨在通过开发基于氧化石墨烯的超薄水选择性膜来显着提高膜性能。该项目旨在确定失效模式，并开发独特的夹层，以使用与Evercloak的卷对卷纳米薄膜印刷技术兼容的方法来稳定超薄薄膜。该项目的成果预计将改善Everlcoak目前的膜技术，使他们能够更快地渗透市场。该项目的成功将使基于膜的制冷成为现实，并实现更有效的冷却以及工业除湿/脱水技术，预计将大大减少社会的环境足迹。
