This vacuum-based ice slurry system offers high-efficiency thermal energy storage, replacing high-GWP refrigerants and traditional chilled water systems. By decoupling ice-making and melting, it enables peak load shifting and better use of renewable energy, significantly reducing building-sector emissions in line with 2050 net-zero goals. With strong industrial potential, it supports the next generation of green cooling and boosts international competitiveness.

This technology pioneers the first continuous-operation vacuum ice slurry system, using flash evaporation at water’s triple point and a dual-layer insulated design to surpass traditional batch systems. With a COP of 5.4 and 150–200% improved heat transfer efficiency, it integrates nano-scale superhydrophobic surfaces to prevent clogging and lower energy use, demonstrating globally competitive cold energy storage innovation.

The patented “Ice Slurry Generation Device,” winner of the Fusheng Cup, showcases strong innovation and application potential. With high COP, modular design, and energy-saving benefits, it is ideal for high cooling-load buildings and AC retrofits, with potential in food processing and thermal management. Industrialization will proceed through licensing and partnerships, supporting deployment across sectors in line with sustainability goals.
