Thermally driven water-based sorption refrigeration is considered a promising strategy to realize near-zero-carbon cooling applications by addressing the urgent global climate challenge caused by conventional chlorofluorocarbon (CFC) refrigerants. However, developing cost-effective and high-performance water-sorption porous materials driven by low-temperature thermal energy is still a significant challenge. Here, we propose a zeolite-like aluminophosphate with SFO topology (EMM-8) for water-sorption-driven refrigeration. The EMM-8 is characterized by 12-membered ring channels with large accessible pore volume and exhibits high water uptake of 0.28 g·g⁻¹ at P/P₀ = 0.2, low-temperature regeneration of 65 °C, fast adsorption kinetics, remarkable hydrothermal stability, and scalable fabrication. Importantly, the water-sorption-based chiller with EMM-8 shows the potential of achieving a record coefficient of performance (COP) of 0.85 at an ultralow-driven temperature of 63 °C. The working performance makes EMM-8 a practical alternative to realize high-efficient ultra-low-temperature-driven refrigeration.

热驱动的水基吸附制冷被认为是通过解决传统氯氟烃 (CFC) 制冷剂引起的紧迫全球气候挑战来实现近零碳冷却应用的有前景的策略。然而，开发由低温热能驱动的具有成本效益和高性能的吸水多孔材料仍然是一项重大挑战。在这里，我们提出了一种具有 SFO 拓扑结构的类沸石磷酸铝 (EMM-8)，用于吸水驱动制冷。EMM-8 的特点是 12 元环通道，具有大的可及孔体积，在P / P _{0处表现出 0.28 g·g} ^-1的高吸水率 = 0.2，65°C的低温再生，快速的吸附动力学，显着的水热稳定性和可扩展的制造。重要的是，采用 EMM-8 的基于吸水的冷却器显示出在 63 °C 的超低驱动温度下实现 0.85 的记录性能系数 (COP) 的潜力。工作性能使EMM-8成为实现高效超低温驱动制冷的实用替代品。
