Device and method for testing thermal stability of phase change material for building

According to the thermal stability testing device of the phase change material for the building and the thermal stability testing method of the phase change material for the building provided by the embodiment of the invention, the heating shell and the shell which are matched in shape are arranged, so that the thickness of the tested material between the heating shell and the shell is basically equal along the heating direction. In a phase change material test, especially a phase change material test with a high cycle index, the tested material is uniformly heated, so that the accuracy of a final result can be ensured, and the regional difference of the property of the tested material caused by non-uniform heating is avoided. 本发明实施例提供的建筑用相变材料的热稳定性测试装置和建筑用相变材料的热稳定性测试方法，通过设置形状相匹配的加热壳体和外壳，使得其二者之间的受试材料沿受热方向厚度基本相等。在相变材料测试试验，特别是高循环次数的相变材料测试试验中，受试材料受热均匀能够保证最终结果的准确性，避免由于受热不均导致的受试材料性质的区域性差别。
