复合相变储能砂浆性能实验研究

Experimental Study on the Properties of Composite Phase Change Material

通过将复合相变储能材料应用在建筑墙体材料中,达到调节室内热舒适度、降低建筑能耗目的。研究了普通砂浆和复合相变储能材料不同龄期的抗折强度和抗压强度,热循环对不同龄期复合相变储能砂浆抗折强度和抗压强度的影响,以及石蜡相变储能砂浆的控温性能。结果表明:复合相变储能砂浆可以满足普通砂浆的基本力学性能要求;热循环后对复合相变控温砂浆力学性能影响很小;相变储能砂浆模拟房内的温度波动小于普通砂浆,可改善居住舒适度。

The composite phase change material was used in the construction of the wall material, to adjust the indoor thermal comfort, reduce building energy consumption purposes. Flexural strength and compressive strength of the ordinary mortar and composite phase change material were studied. Effect of thermal cycling on flexural strength and compressive strength of composite phase change energy storage mortar with different ages, and temperature control properties of paraffin wax phase change mortar were studied. The results showed that the mechanical properties of composite phase change energy storage mortar can meet the basic requirements of of ordinary mortar. The thermal cycling has little effect on the mechanical properties of the composite phase simulation room temperature fluctuation is less change temperature control mortar. Phase change mortar than ordinary mortar, which improve the living comfort.
