| 摘 要： | 通过实验得出了石蜡复合体系的相变温度、相变潜热值；对比了陶粒、高性能吸附剂对石蜡的吸附能力；测试了掺入相变储能骨料的水泥试件的强度、导热性能。结果表明：经过比较，低熔点的52号石蜡与27号液体石蜡的复合体系的相变温度低．热焓值更大；高性能吸附剂对石蜡的吸附性比陶粒更好；掺入适量的相变储能骨料对水泥试件的导热性没有很大影响，但在一定程度上会降低试件的强度。

| Abstract: | The phase change temperature and the phase change latent heat value of the compound system of paraffin wax are obtained through the experiment; the adsorption ability to paraffin wax of ceramic and high-perfonnance adsorbents are compared, testing the strength and thermal conductivity of cement specimens mixed with phase change energy storage aggregate. The results show that, after comparison, the phase transition temperature of the composite phase change materials with low melting point of 52 and 27 liquid paraffin wax is low,but the heat enthalpy is larger; The adsorption of high-pegrormance adsorbents is better than Tao lid; The thermal conductivity of the specimen change little by mixing with qppropriate amount of phase change energy storage materials to cement, but the specimen＇s strength will reduce in a certain extent. |
