通过采用相变材料（PCM）并改进其结构设计，可以进一步提高平板太阳能集热器的整体导热系数和蓄热能力，从而提高集热器的稳定性和集热效率。本研究以十水硫酸钠（SSD, Na2SO4·10H2O）和三水乙酸钠（SAT, CH3COONa·3H2O）为原料，提出了一种新型二元混合水合盐（SSD/SAT）的制备工艺，解决了相分离和过冷难题。当材料的相变温度为61.71℃时，相变潜热达到229 J/g−1。此外，还对SSD/SAT材料集成到v型波纹平板太阳能集热器（VC-FPSC）中的集热性能进行了数值模拟。人们发现集热器能够扩展热量并提高效率。
Flat plate solar air collectors can further increase their overall thermal conductivity and heat storage capacity by using phase change materials (PCM) and refining their structural design, which will increase their stability and effectiveness of heat collection. Based on sodium sulfate decahydrate (SSD, Na2SO4·10H2O) and sodium acetate trihydrate (SAT, CH3COONa·3H2O), this research proposes a novel manufacturing procedure to manufacture a new binary mixed hydrated salt (SSD/SAT), which addresses phase separation and undercooling difficulties.The latent heat of phase transition hits 229 J/g−1when the material's phase transition temperature is 61.71 °C. Furthermore, the numerical modeling of the SSD/SAT material's heat collection performance was conducted when it was integrated into a V-corrugated flat plate solar collector (VC-FPSC). The collector has been found to be able to extend the heat and boost the efficiency.
