摘要：A novel synergistic eutectic phase change material (PCM) was successfully synthesized, in which sodium acetate trihydrate (SAT) effectively reduces the phase change point of aluminum potassium sulfate dodecahydrate (APSD), while APSD simultaneously suppresses phase separation in SAT. Through systematic performance enhancement, the final composite PCM exhibits remarkable properties: supercooling below 1 degrees C, thermal energy storage (TES) density of 214.77 kJ/kg, 67% improvement in thermal conductivity, and excellent cycling stability. The volume expansion during solid-liquid phase transition was measured as 9.02%. Brass H68 was identified as the optimal encapsulation material due to its superior compatibility. Numerical simulations demonstrate that at a low cold water flow rate of 1 L/min, the PCM system sustained a 40 degrees C outlet temperature for 22.75 min-a 34.85% improvement over the pure water system, providing valuable insights for its industrial implementation.
