摘要：相变材料作为一种储能材料，具有较强的储存和释放能量的能力。无机相变材料六水氯化钙具有较大的潜热值，是一种良好的储能介质。通过纳米二氧化硅改性六水氯化钙，材料过冷度得到有效改善。为模拟纳米复合六水氯化钙在绿色建筑中对室内温度的调节作用，设计并制作了合适的建筑模型。结果表明，改性六水氯化钙能控制室内温度，阻止外界温度快速影响室内温度。

Abstract：Phase change materials have been seen as energy storage materials，and they have a powerful capacity in absorbing and releasing energy. Calcium chloride hexahydrate contains huge latent heat value，and it can be seen as an essential energy storage media. Via modifying properties by nano silica， calcium chloride hexahydrate will improve original supercoiling degree wonderfully. In order to simulate the adjustment ability of nano-composite calcium chloride hexahydrate in indoor temperature of green houses，suitable green-house models are designed and made. Experimental results showed that modified calcium chloride hexahydrate can help control indoor temperature and prevent external energy from entering the room.
