[0002] As we all know, building energy conservation testing is an activity to detect and evaluate the building energy utilization efficiency and the implementation of energy-saving measures. It aims to ensure that the building meets energy-saving standards, reduce energy consumption, and improve energy utilization efficiency. In building energy conservation testing, thermal conduction testing is a very important link. In order to facilitate the thermal conduction test of building energy conservation testing, we propose a thermal conduction testing equipment for building energy conservation testing.

A telescopic heat-conducting box is connected to the side of the bottom distribution pipe, and a detection inner plate is connected to the side of the telescopic heat-conducting box. Top cooling pumps are installed on both sides of the external low-temperature barrel, and the ends of the two top cooling pumps are connected to the top distribution pipe. The outer side of the top distribution pipe is connected to the two corners of the top of the corresponding telescopic heat-conducting box through a pipeline.

[0026] The temperature sensor 4 and the electromagnet 16 in this embodiment are conventional devices purchased on the market and known to those skilled in the art. In the present invention, we only use them without improving their structure and function. For those skilled in the art, their setting method, installation method and electrical connection method only need to be debugged and operated according to the requirements of their instruction manual, and will not be described in detail here.

[0027] To sum up, the working principle of the thermal conduction test equipment for building energy-saving detection is as follows: before use, first, a control circuit is installed to match the temperature sensor 4 and the electromagnet 16. The guide wire of the control circuit can be installed with the first traction rope 41 to form a guide installation, or it can be installed with the second traction rope 43 to form a guide installation. Then, a pumping tube is installed to connect the air supply hole 7 and the pumping tube is connected to the external air pump. Finally, the first storage box 25 is pre-loaded with a heat-insulating fluid. The heat-insulating fluid can be a flowable liquid material or a solid material in the form of powder particles. When in use, the two first traction ropes 41 are fixedly installed at one end of the target building, and the two second traction ropes 43 are fixedly installed at the other end of the target building. When the first traction rope 41 and the second traction rope 43 are fixedly installed relative to the target building, the outer sealing rubber ring 11 should be controlled to fit with the test surface of the target building, as shown in the attached figure. Fig.19The diagram is a schematic diagram of the high and low installation of the first traction rope 41 relative to the second traction rope 43. During the installation process of the second traction rope 43, the length of the second traction rope 43 should be controlled so that the first traction rope 41 and the second traction rope 43 are both in a taut state. In this way, under the auxiliary guiding action of the first guide bend 40 and the second guide bend 42, the outer sealing rubber ring 11 can be better fitted and pressed with the target building. Since the relative distances between the inner rubber ring 12 and the outer sealing rubber ring 11 and the target building are consistent, when the outer sealing rubber ring 11 is in contact and pressed with the target building, the inner rubber ring 12 and the target building are also in contact and pressed with each other. Thereafter, an independent space isolated from the outside world is formed between the inner rubber ring 12, the outer sealing rubber ring 11, the installation outer frame 1 and the target building. Due to the elastic action of the arc spring 22, the rotation stability of the rotating cloth ring 21 relative to the installation outer frame 1 can be maintained. Therefore, the first storage box 25 is located above the second storage box 26, and under the premise of not applying driving force to the first driving rope 44 and the second driving rope 45, under the elastic action of the two elastic springs 33, the two gates 32 will respectively block the feed channel 29 and the discharge channel 30. In this state, the heat-insulating fluid in the first storage box 25 will not flow through the feed channel 29 under the action of its own gravity. Thereafter, the gate 32 inserted into the feed channel 29 is pulled out relative to the feed channel 29 by pulling the first driving rope 44. Thereafter, the blocking effect of the feed channel 29 fails, and the heat-insulating fluid in the first storage box 25 will flow through the feed channel 29 under the action of its own gravity, and finally enter the independent space formed by the inner rubber ring 12, the outer sealing rubber ring 11, the installation outer frame 1 and the target building, thereby improving the sealing and heat-insulating effect at the contact between the installation outer frame 1 and the target building.

[0028] Furthermore, an electromagnetic field is generated by controlling the electromagnet 16 to be energized, and a mutually repulsive magnetic force is formed between the generated electromagnetic field and the permanent magnet 15. Under the action of the magnetic repulsive force, the electromagnet 16 will be moved away from the permanent magnet 15, and the moving permanent magnet 15 will drive the sliding cylinder 6 to move away from the target building relative to the installation cylinder 5, so that the inner sealing rubber ring 13 is moved away from the target building, so that the space in the temperature transfer inner frame 2 and the space in the installation outer frame 1 are interconnected, and the interconnected state is maintained by pumping normal temperature air into the pumping pipe through the air pump. The normal temperature air will be dispersed into the four supply holes 10 through the guidance of the air supply hole 7, and after forming a pressure-maintaining flow in the temperature transfer inner frame 2, it will be discharged through the extension pipe 55, the return hole 9 and the return air hole 8, so that the space in the temperature transfer inner frame 2 and the space in the installation outer frame 1 that are interconnected have the same temperature, and then the input current of the electromagnet 16 is adjusted to form a mutually attractive magnetic force between the electromagnet 16 and the permanent magnet 15. Under the action of the mutually attractive magnetic force, the permanent magnet 15 will be close to the target building until the inner sealing rubber ring 13 is pressed and fitted relative to the target building. Due to the elastic action of the double limit spring 14, when the inner sealing rubber ring 13 is pressed and fitted relative to the target building, the double limit spring 14 can maintain and promote the pressing and further tightening of the inner sealing rubber ring 13 relative to the target building, so as to ensure that the heat transfer inner frame 2 forms a good spatial isolation relative to the target building, and also separate the internal space of the heat transfer inner frame 2 from the internal space of the installation outer frame 1. Then, high-temperature air is pumped into the heat transfer inner frame 2 through an air pump to increase the temperature inside the heat transfer inner frame 2, and four temperature sensors 4 are started to realize temperature detection of different areas in the installation outer frame 1. The installation outer frame 1 and the heat transfer inner frame 2 are both made of materials with good heat insulation effect or are coated with heat insulation coatings. Therefore, when the temperature inside the heat transfer inner frame 2 rises, the heat inside the heat transfer inner frame 2 is conducted to the installation outer frame 1, mainly through the target building. Fig. 20 As shown, the direction of the arc arrow in the figure is a schematic diagram of the direction in which heat is effectively diffused through the target building. The temperature transfer inner frame 2 is controlled to have continuous and stable high-temperature air pumped in, and the temperatures of four detection points are detected in real time through four temperature sensors 4. As time goes by, the thermal conduction test of the target building is realized through the temperature rise of the four temperature sensors 4, as shown in the attached figure. Figure 1As shown, the temperature transfer inner frame 2 is eccentrically arranged in the installation outer frame 1, and the four support tubes 3 are arranged in an axially symmetrical and equiangular form in the installation outer frame 1, so the four temperature sensors 4 will be at different distances relative to the temperature transfer inner frame 2. During the actual test, if the temperature sensor 4 farther away from the temperature transfer inner frame 2 among the four temperature sensors 4 has a lower temperature reading than the temperature sensor 4 closer to the temperature transfer inner frame 2, it means that the test data is valid. According to the reading of the temperature sensor 4, when the temperature of the heat source in the temperature transfer inner frame 2 is the same and the conduction time is the same, the higher the temperature rise change of the corresponding temperature sensor 4, the higher the thermal conduction efficiency of the target building, and the worse the energy saving performance of the corresponding target building.

[0029] After the test is completed, stop pumping air into the temperature transfer inner frame 2, and pull the second driving rope 45 to pull a gate 32 near the lower side relative to the discharge channel 30. Thereafter, under the action of gravity, the heat-insulating fluid filled between the outer sealing rubber ring 11 and the inner sleeve rubber ring 12 will flow into the second storage box 26. When the heat-insulating fluid has completed flowing, the pulling force acting on the second driving rope 45 is released. Thereafter, the gate 32 near the lower side will be reinserted into the discharge channel 30 to close the discharge channel 30. Then, the positions of the installation outer frame 1 and the temperature transfer inner frame 2 relative to the target building are adjusted to achieve the corresponding adjustment of the next target building or the next target detection point on the same target building. After the adjustment is completed, since the heat-insulating fluid is stored in the second storage box 26, when the heat-insulating fluid needs to be filled into the area between the outer sealing rubber ring 11 and the inner sleeve rubber ring 12 for the second time, it is necessary to pull the adjusting traction rope 24 to make the transfer cloth ring 21 overcome the arc spring 22. A rotation adjustment is formed relative to the mounting outer frame 1, and the rotation adjustment angle is one hundred and eighty degrees. The pulling force acting on the adjusting traction rope 24 is maintained, so that the first storage box 25 and the second storage box 26 exchange their upper and lower positions. Thereafter, the first driving rope 44 is pulled again to open a gate 32 near the upper side, so that the insulation fluid in the second storage box 26 can flow out. Similarly, when the insulation fluid is used up, it will be discharged into the first storage box 25. Therefore, the insulation fluid will be stored alternately between the first storage box 25 and the second storage box 26, and finally the insulation fluid can be used and recycled. Since the insulation fluid is in contact with the target building during use, it is inevitable that there will be consumption when the insulation fluid is recycled. Therefore, the insulation fluid initially added to the first storage box 25 should be greater than the amount of insulation fluid required for a single use, and the insulation fluid should be replenished in stages as the insulation fluid is consumed.
