At present, the annual completed construction area in my country is about 2 billion m2, of which public buildings account for about 400 million m2. The area of ​​large public buildings above 20,000 m2 accounts for less than 4% of the urban construction area, but their energy consumption accounts for more than 20% of the building energy consumption, and the power consumption per unit area is 10 to 15 times that of ordinary residential buildings. In the annual energy consumption of public buildings (especially large shopping malls, high-end hotels, high-end office buildings, etc.), about 50% to 60% is consumed in air conditioning, refrigeration and heating systems, and 20% to 30% is used for lighting.

[0003] From this, it can be seen that the energy consumption of air-conditioning, refrigeration and heating systems has a great impact on building energy consumption. In order to achieve the detection of building energy efficiency and better realize energy saving, it is necessary to detect the energy efficiency of air-conditioning, refrigeration and heating systems.

[0004] When the existing building energy efficiency detection device detects the air conditioning energy efficiency, it is necessary to connect the air inlet of the detection device with the air outlet of the central air conditioner. Since the central air conditioner is installed on the roof, the staff needs to lift the detection device upwards, which makes the operator very laborious during the detection process.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figures 1 to 3 As shown, an embodiment of the present application provides a building energy efficiency detection device, including a detection box 1, one end of the detection box 1 is connected to an air duct 2, the end of the air duct 2 away from the detection box 1 is connected to an air inlet scoop 3, a wind speed detector 4 is fixedly connected to the air inlet scoop 3, a temperature sensor 5 is fixedly connected to the detection box 1, the end of the detection box 1 away from the air duct 2 is connected to a telescopic rod 6, a controller 612 and a display screen 611 are provided on the telescopic rod 6, and the wind speed detector 4, the temperature sensor 5 and the display screen 611 are electrically connected to the controller 612 respectively.

[0020] Specifically, the controller 612 includes a timing module, and the display screen 611 displays wind speed, temperature and time. The display screen is arranged at the end of the telescopic rod 6 away from the detection box so that the staff can view the data. A power module is also arranged inside the telescopic rod 6, and the wind speed detector 4, temperature sensor 5, controller 612 and display screen 611 are all electrically connected to the power module.

[0021] During operation, the telescopic rod 6 can be adjusted according to the height of the air conditioner, so that the staff can save effort when holding the telescopic rod 6 to perform air conditioner energy efficiency testing. A wind speed detector 4 is arranged on the air inlet scoop 3 to detect the wind speed of the air outlet of the air conditioner. The air-conditioned wind reaches the testing box 1 through the air duct 2. The air-conditioned wind affects the temperature in the testing box 1. The temperature sensor 5 feeds back the temperature in the testing box 1 in real time. The air conditioning energy efficiency can be calculated by calculating the air conditioning power, air conditioning wind speed, volume of the testing box 1, front and rear temperature difference of the testing box 1 and the time difference between the front and rear. The air duct can be set to be as short as possible to avoid increased energy consumption during air conditioning wind transmission.

[0022] The above-mentioned structure is set up, by connecting the telescopic rod 6 to the detection box 1, so that the staff can adjust the telescopic rod 6 according to the height of the air conditioner, which makes the staff more labor-saving and can adapt to air conditioners of different heights. The telescopic rod 6 is set at the end of the detection box 1 away from the air duct 2, so that when the telescopic rod 6 is extended or retracted, it will not affect the flow path of the air conditioning wind, thereby avoiding heat loss of the air conditioning wind.

[0023] In this embodiment, the telescopic rod 6 includes a sleeve 61 and a telescopic member 62 . The inner wall of the sleeve 61 is provided with a first thread, and the outer wall of the telescopic member 62 is provided with a second thread 623 . The first thread is threadably connected to the second thread 623 .

[0024] The above structure is set up, the telescopic rod 6 is set as a pipe sleeve 61 and a telescopic member 62 located inside the pipe sleeve 61, and the pipe sleeve 61 and the telescopic member 62 are threadedly connected. The length of the telescopic rod 6 can be changed by rotating the telescopic member 62, which makes telescoping more convenient.

[0025] In this embodiment, a first sealing ring 31 is provided on the air inlet scoop 3 .

[0026] The above structure is arranged such that, by arranging the first sealing ring 31 on the air inlet scoop 3, there is no air leakage between the air inlet scoop 3 and the air outlet of the air conditioner.

[0027] In this embodiment, the outer walls of the detection box 1 , the air duct 2 and the air inlet hopper 3 are all wrapped with a heat preservation plate 7 .

[0028] The above structure can reduce the heat loss caused by the transmission of air conditioning wind by arranging the insulation board 7 on the outer walls of the detection box 1, the air duct 2 and the air inlet scoop 3.

[0029] In this embodiment, the detection box 1 is provided with a vent, a second sealing ring 12 is provided on the peripheral wall of the vent, a cover 11 matching the vent is provided on the vent, and the cover 11 abuts against the second sealing ring 12 .

[0030] The above structure is set up by arranging a ventilation hole on the test box 1, so as to facilitate ventilation of the test box after the test is completed, so as to prevent the residual air in the test box 1 after the previous test from affecting the next test. A cover 11 adapted to the ventilation hole is set, and a second sealing ring 12 is set on the ventilation hole, so as to ensure the airtightness of the test box 1 when the cover 11 is closed.

[0031] In this embodiment, the detection box 1 is connected to a connecting block 13, and a rotating block 131 is fixedly connected to the connecting block 13. The end of the telescopic rod 6 close to the detection box 1 is fixedly connected to an ear plate 621, and the ear plates 621 are arranged in two symmetrical forms. The rotating block 131 is rotatably connected to one of the ear plates 621, and the other ear plate 621 is threadedly connected to a bolt 622 that can fix the connecting block 13.

[0032] During operation, when the direction of the air outlet of the air conditioner is not vertically downward, the bolt 622 can be loosened first, and the rotating block 131 on the connecting block 13 rotates on the ear plate where it is located. When it rotates to a suitable angle, the bolt is tightened to fix the connecting block, and the direction of the detection box, the air duct and the air inlet hopper relative to the telescopic rod is changed to better adapt to the location of the air conditioner.

[0033] The above structure is arranged by arranging a connecting block 13 on the detection box 1, and arranging a rotating block 131 on the connecting block 13, and arranging two symmetrical ear plates 621 on the telescopic rod 6, and the rotating block 131 is rotatably connected to one of the ear plates 621, and a bolt 622 that can fix the connecting block 13 is arranged on the other ear plate 621, so that the air inlet scoop 3, the air duct 2 and the detection box 1 can be adjusted in angle relative to the telescopic rod 6, so as to facilitate the detection of the air conditioner at different angles.
