【摘要】 TiO2-WATER相变蓄冷纳米复合材料是一种新型的空调蓄冷介质,用差示扫描量热法测试了其熔解潜热,结果显示熔解潜热比水的要低,但由于其熔解温度低于水的熔解温度,相变蓄冷纳米复合材料比水具有更大的显热储存能力。更多还原

【Abstract】 TiO2-WATER phase change nanocomposites for cool storage is a new sort of cool storage material to be used in air conditioning system. Heat of fusion is one of the most important properties of PCNs(Phase Change Nanocomposites) , and the magnitude of which is measured by differential scanning caforimetry. The results demonstrate that white the latent heat of fusion of TiO2 - WATER PCNs is less than that of water, the sensible heat of TiO2- WATER PCNs is more great, because of their tower fusion temperature.更多还原
