Technical Field

[0002] As a key indicator of building energy conservation, the heat transfer coefficient of building exterior walls has been discussed by relevant industry experts. However, the traditional method for detecting the heat transfer coefficient of building exterior walls is a laboratory simulation experiment, which has shortcomings such as a long cycle.
[0003] The existing patent (Announcement No.: CN202230042U) discloses a hot and cold box for detecting the heat transfer coefficient of the building exterior wall, which includes a box, a semiconductor refrigerator, a DC power supply, a controller, and a temperature sensor. The box is a square or rectangular structure with an opening. The semiconductor refrigerator is installed at the bottom of the box, and its two sides are located inside and outside the box respectively. A temperature sensor is placed in the box. The semiconductor refrigerator is connected to the DC power supply through the controller, and the temperature sensor is connected to the controller. When in use, the two hot and cold boxes are connected as a cold box and a hot box respectively and installed on the opposite sides of the exterior wall. The heat transfer coefficient of the exterior wall is then measured with a heat flux meter. The utility model has the following characteristics: semiconductor refrigerators are used for cooling or heating, there are no sliding parts, the equipment has good working stability, high safety, and no refrigerant pollution; during use, the temperature of the inner and outer surfaces of the exterior wall remains stable, which can prevent the outer surface of the inspected area of the exterior wall from being invaded by rain and snow and direct sunlight.
[0004] However, during use, the above-mentioned detection device is installed on the opposite sides of the object to be measured through the hot and cold boxes, and the opening of the box is facing the surface of the object to be measured and is sealed. However, in actual use, the two boxes are installed on both sides of the wall. Due to the limitation that the wall is invisible, deviations are prone to occur during the alignment process, which makes it impossible to align the two boxes accurately, thereby affecting the thermal convection of the temperatures of the two boxes, resulting in deviations in the detection results.
