[0037] Electric heater 6: installed on the upper and lower sides of the right box 2, used to simulate different temperature environments to test the thermal insulation performance of the wall at different temperatures;
[0038] The electric heater 6 can quickly and accurately adjust the temperature in the test area to meet different test requirements.

[0040] Top cover 11: It is installed on one side of the upper end of the side shell 10 by rotation, which is convenient for opening and closing, and is convenient for operators to operate and observe the test area.
[0041] Side panels 7: located at the four corners of the left box body 1 and the right box body 2, fixedly connected to the box body, and used to enhance the stability and load-bearing capacity of the box body.

[0048] Instructions for this program:
[0049] Adjust the height of the pulley 9: Turn the adjusting screw 8 so that the pulley 9 moves downward until it contacts the ground. In this way, the device can be easily moved on the ground via the pulley 9.
[0050] Separate the box: pull the insertion rod 16 to disengage one end of it from the limiting hole 18, and then flip up and open the fixing plate 14. In this way, the left box 1 and the right box 2 can be easily separated.
[0051] Place the boxes: Place the left box 1 and the right box 2 on both sides of the building wall, making sure they maintain an appropriate distance from the wall.
[0052] Apply thermal insulation glue: Take out the thermal insulation glue from the inside of the side shell 10, fit the glue grooves 20 of the left box 1 and the right box 2 to the wall, and then fill the glue grooves 20 with thermal insulation glue to ensure that the box fits tightly to the wall without any gap.
[0053] Start the test equipment: turn on the electric heater 6 inside the right box 2 for heating, and start the temperature sensor 5 at the same time. The temperature sensor 5 should be connected to a temperature recorder or a data acquisition system to record temperature data in real time.
[0054] The working principle of this scheme is as follows: Turn the adjusting screw 8 to move the pulley 9 downward, and the pulley 9 contacts the ground to facilitate the movement of the equipment. Pull the plug rod 16 to make one end of it disengage from the limit hole 18, and then flip up and open the fixing plate 14, so that the left box 1 and the right box 2 can be separated, and the left box 1 and the right box 2 are placed on both sides of the building wall respectively. Take out the insulation glue from the inside of the side shell 10, and fit the glue grooves 20 of the left box 1 and the right box 2 to the wall. Put the insulation glue into the glue grooves 20, so that the left box 1 and the right box 2 are closely fitted to the wall, and turn on the electric heater 6. During heating, the temperature sensor 5 is turned on. The temperature sensor 5 is connected to a temperature recorder or a data acquisition system to record temperature data on both sides for a period of time to obtain sufficient temperature change data. By comparing the temperature data on both sides, the thermal insulation performance of the wall is evaluated. Parameters such as temperature difference and temperature change rate over time can be calculated to quantify the thermal insulation effect. Based on the results of data analysis, the thermal insulation performance of the wall is explained. If the temperature difference between the heated side and the unheated side is small, and the temperature changes slowly over time, it means that the thermal insulation performance of the wall is good.
