[0041] Reference Figures 1 to 4The technical solution of this utility model relates to an air conditioning performance testing device, including an inner environmental chamber 100, which is equipped with a condition processing cabinet 300 and an air volume measuring device 400; an outer environmental chamber 200, located on one side of the inner environmental chamber 100, which is also equipped with a condition processing cabinet 300 and an air volume measuring device 400; an isolation wall 500, located between the inner environmental chamber 100 and the outer environmental chamber 200, which has a step portion 510 and a hollow mounting groove; and a testing fixture 600, located in the mounting groove, which has a clearance hole in the middle. The testing fixture 600 is used to install an air conditioning prototype, and the clearance hole is used to avoid the inner air inlet and inner air outlet of the air conditioning prototype.

[0042] Understandably, the inner environment chamber 100 is used to simulate the interior environment of a car or bus, while the outer environment chamber 200 is used to simulate the outdoor environment. The air parameters of the inner environment chamber 100 and the outer environment chamber 200 are set by the working condition processing cabinet 300, so that the temperature environment of the inner environment chamber 100 and the outer environment chamber 200 meets different test requirements and simulates test environments under various working conditions. A drainage component is connected between the test fixture 600 and the mounting slot, and the two are sealed. The air conditioner prototype is placed in the test fixture 600 and is also sealed.

[0043] The application of the above-mentioned air conditioning performance testing device has at least the following beneficial effects: By setting an isolation wall 500 between the inner environmental chamber 100 and the outer environmental chamber 200, and setting a step 510 on the isolation wall 500, the air conditioning prototype is set on the mounting groove of the step 510 through the testing fixture 600. The operation is simple and easy, and different air conditioning prototypes only need to replace the corresponding fixtures, which improves the versatility. At the same time, since the air conditioning prototype is directly installed in the mounting groove of the step 510, the duct connection link is reduced, avoiding interference factors that may be caused by the duct, and improving the accuracy of the test.

[0044] According to some embodiments of this utility model, the test fixture 600 includes a frame body 610 and a mounting body 620. The mounting body 620 is disposed inside the frame body 610, and the clearance hole 621 is disposed in the middle of the mounting body 620. The mounting body 620 is square in shape, and the frame body 610 is disposed in the mounting groove. By setting the mounting body 620 to be square, it can simulate the roof of an indoor warehouse or the roof of a vehicle. At the same time, it can also be adapted to place and test various air conditioner prototypes of different specifications.

[0045] According to some embodiments of this utility model, a drainage groove 630 is formed between the inner wall of the mounting body 620 and the frame body 610, and a water outlet is provided in the frame body 610. When the prototype generates condensate during the test, it can flow out through the drainage groove 630 and the water outlet to avoid water accumulation affecting the test.

[0046] According to some embodiments of this utility model, multiple connecting rods 640 are provided between the inner wall of the frame body 610 and the mounting body 620. The connecting rods 640 are suspended in the air, and the drainage channel 630 is located below the connecting rods 640. The connecting rods 640 strengthen the connection structure between the mounting body 620 and the frame body 610, and the suspended connecting rods 640 ensure the continuity of the drainage channel 630.

[0047] According to some embodiments of this utility model, a first sampling rake 210 is provided on the step portion 510 for collecting air from the outer environmental chamber 200, and a second sampling rake is provided in the inner environmental chamber 100 for collecting air from the inner environmental chamber 100. By collecting air from the outer environmental chamber 200 and the inner environmental chamber 100 through the first sampling rake 210 and the second sampling rake, environmental factors such as temperature and humidity of the outer environmental chamber 200 and the inner environmental chamber 100 can be controlled and detected.

[0048] According to some embodiments of the present invention, the air inlet of the air volume measuring device 400 is connected to a telescopic hose 410, and the end of the telescopic hose 410 is connected to an air inlet box 420. The bottom of the air inlet box 420 is provided with four casters 430. Through the action of the casters 430, the air inlet box 420 can be pushed to a position close to the air outlet inside the test sample for air volume measurement. The telescopic hose 410 can ensure that the air inlet box 420 can move freely without interference when the air volume measuring device 400 does not move.

[0049] According to some embodiments of this utility model, it also includes a telescopic bracket 440 and a lifting mechanism 450. Four casters 430 are located at the bottom of the telescopic bracket 440, an air inlet box 420 is located at the upper end of the telescopic bracket 440, and the lifting mechanism 450 is located inside the telescopic bracket 440. The output end of the lifting mechanism 450 is connected to the upper end of the telescopic bracket 440. By driving the lifting mechanism 450, the telescopic bracket 440 is raised and lowered, so that the air inlet box 420 is located at different heights. The lifting mechanism 450 includes a power component 451, a lead screw structure 452, and a scissor mechanism 453. The lead screw structure 452 is connected to the output end of the power component 451, and the scissor mechanism 453 is connected to the lower end of the lead screw structure 451. One end of the component is connected to the bottom of the telescopic bracket 440, and the other end is connected to the lead screw structure 452. The upper part of the scissor structure 453 is connected to the upper part of the telescopic bracket 440. An operating handle is also provided. The operating handle is electrically connected to the power component 451 and is used to drive the scissor structure 453 to rise or fall. By driving the power component 451 through the operating handle, the lead screw structure 452 converts the rotational motion of the power component 451 into linear motion, thereby causing the lower ends of the scissor structure 453 to move closer or further apart, thereby causing the telescopic bracket 440 to rise or fall, thereby adjusting the height of the air inlet box 420 to be close to the inner air outlet of air conditioner prototypes of different specifications for air volume testing.

[0050] According to some embodiments of this utility model, the working condition processing cabinet 300 includes a shell 310, an evaporator 320, and a fan 330. The evaporator 320 is located at the bottom of the shell 310, and the fan 330 is located at the top of the shell 310. A partition is provided between the fan 330 and the evaporator 320, and a connecting hole is provided on the partition. The fan 330 is provided with an air outlet that connects to the outside of the shell 310. Air is drawn upward from the bottom of the shell 310 by the fan 330, and the air cooled by the evaporator 320 is discharged upward through the air outlet of the fan 330 to the inner environmental chamber 100 and the outer environmental chamber 200, thereby changing the temperature of the inner environmental chamber 100 or the outer environmental chamber 200, thereby simulating various different working conditions for testing.
