摘　　要：TiO_2-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。TiO2-WATER phase change nanocomposites for cool storage is a new sort of cool storage materials 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 calorimetry. The results demonstrate that while the latent heat of fusion of TiO2-WATER PCNs is less than that of water, the sensible heat of TiO2- WATER PCNs is much greater, because of their lower fusion temperature.
