There is broad demand for humidity control for industrial, commercial, and residential applications. Current humidity pumping technologies require intensive maintenance because of the complexity of their mechanical structures. Furthermore, indirect utilization of solar energy increases both cost and energy loss. Here, we demonstrate a new humidity pumping concept based on multilayer moisture permeable panels. Such panels, with a simple structure, may allow the penetration of moisture from indoor (adsorption) to outdoor (desorption) with little heat loss. One-sun illumination is introduced as the direct energy source. A proof-of-concept prototype is designed and established, successfully dehumidifying indoor air with the best dehumidification rate of 33.8 g⋅m⋅h. By applying such humidity pump, the indoor latent heat load can be handled independently, without any auxiliary unit, thus consuming no electricity.
工业、商业和住宅应用对湿度控制有着广泛的需求。当前的湿度泵送技术由于其机械结构的复杂性而需要大量维护。此外，太阳能的间接利用增加了成本和能量损失。在此，我们展示了一种基于多层透湿面板的新型湿度泵送概念。这种结构简单的面板可以使水分在几乎没有热损失的情况下从室内（吸附）渗透到室外（解吸）。引入一个太阳光照作为直接能源。设计并建立了一个概念验证原型，成功地对室内空气进行除湿，最佳除湿率为33.8 g·m·h。通过应用这种湿度泵，可以独立处理室内潜热负荷，无需任何辅助单元，从而不消耗电力。
