相变储能混凝土比热容的测定研究

Research on measurement of phase-changing energy-storing concrete’s specific heat capacity

介绍了利用准稳态法测得相变储能混凝土的比热容,对在相变材料处于凝固状态,熔融状态,以及固液共存状态时比热容随温度的变化情况进行了分析,结果显示:随着温度的升高,相变储能混凝土的比热容逐渐增加,但在进入固液共存区时存在突变的现象,为相关研究奠定基础。

The study introduces the specific heat capacity of the phase-changing energy-storing concrete by adopting the quasi steady state method,analyzes the changes of the specific heat capacity along with the temperature when the phase-changing materials are in the solidification state,the molten state,and the solid-liquid coexistence state,and displays by the results that the specific heat capacity of the phase-changing energy-storing concrete also increases along with the higher temperature,however,the mutation occurred in the solid-liquid coexistence state,so as to lay the foundation for relative researches.
