[0002] The detection of heat transfer coefficient of building wall structure is one of the main contents of building energy-saving detection and evaluation technology. The heat transfer coefficient of building wall structure is carried out according to the theory of one-dimensional heat conduction, that is, the heat transfer coefficient K includes all structural layers of the wall and the air boundary layers on both sides. It characterizes the thermal performance of the wall insulation system. Studies have shown that the reduction of the heat transfer coefficient of the exterior wall will significantly reduce the energy consumption of the building. When detecting the heat transfer coefficient of the existing building wall, it is usually necessary to stick the sensor on the wall with tape, and then connect it to the detector host through a wire, so that the heat transfer coefficient of the wall is calculated by the detector host and displayed on the host. The method of sticking the sensor on the wall with tape is more troublesome and unstable.
