Abstract: According to the dynamic heat transfer of the wall material in the actual environment, a dynamic test method for the heat storage and release performance of the wall material is designed. The wall material is placed between the hot room and the cold room to heat and cool the hot room environment. The temperature changes of the wall material surface and the indoor environment are recorded, and the thermal performance of the wall material is analyzed. According to the results of delay time, attenuation coefficient, heating and cooling curve, the thermal insulation performance of the wall material is evaluated, and the performance of reflective thermal insulation coating composite wall material is tested. The results show that this method can test the thermal insulation performance of wall material in the laboratory, and reflect the dynamic heat transfer process of wall material. This method is simple and feasible, and the test results are reliable.
