[0031] The high-pressure output terminal H of the air conditioning compressor 10 is connected to the input terminal of the condenser 11 and the first terminal of the first connecting valve 12, respectively. Its low-pressure input terminal L is connected to the first output terminal of the expansion valve 13 and the first terminal of the second connecting valve 14, respectively. Its control terminal is connected to the first communication terminal of the controller 15.

[0032] The output end of the condenser 11 is connected to the input end of the drying bottle 16;

[0033] The output end of the drying bottle 16 is connected to the first input end of the expansion valve 13;

[0034] The second output end and the second input end of the expansion valve 13 are respectively connected to the input end and the output end of the evaporator 17;

[0035] The first data terminal of the controller 15 is connected to the data terminal of the operation panel 18.

[0036] In this embodiment, the air conditioning compressor 10 is a conventional model, which can be selected according to actual needs. The condenser 11 is a conventional model. The first connecting valve 12 and the second connecting valve 14 are both conventional connecting valves, which can be two-way valves, three-way valves, or other types of valves, depending on the actual implementation requirements. The expansion valve 13 can be composed of two conventional expansion valves, where the input and output ends of one conventional expansion valve correspond to the first input and second output ends of the expansion valve 13, and the input and output ends of the other conventional expansion valve correspond to the second input and first output ends of the expansion valve 13. The controller 15 is a conventional design and can be implemented based on a microcontroller. The dryer bottle 16 is a conventional model. The evaporator 17 is based on a conventional evaporator; for example, a protective enclosure can be set outside a conventional evaporator to form the evaporator 17. The operation panel 18 can be a conventional touch screen, and is also equipped with physical buttons commonly found in air conditioning systems. The operation panel 18 can be used to control the operation of the air conditioning compressor 10, and the corresponding operation commands are sent to the air conditioning compressor 10 by the controller 15.

[0037] In one specific implementation, when the teaching test bench structure for the air conditioning compressor of a new energy vehicle is applied to a complete vehicle, the first connecting valve 12 and the second connecting valve 14 on both sides can be adjusted to the air conditioning charging machine 28, connecting all sections of the pipeline, which can realize the replacement and charging of refrigerant in the air conditioning system. Alternatively, the first connecting valve 12 and the second connecting valve 14 on both sides can be adjusted to the charging and suction integrated air pump 29, connecting all sections of the pipeline, using the compressed air output by the charging and suction integrated air pump 29 to check the airtightness of the pipeline, and also using the charging and suction integrated air pump 29 to perform a vacuum operation on the pipeline, removing air and moisture from the air conditioning system.

[0038] Meanwhile, when the air conditioning compressor 10 is removed from the vehicle or used for teaching purposes alone, the first connecting valve 12 and the second connecting valve 14 on both sides can be adjusted to the charging and suction integrated air pump 29. The various pipelines in the teaching test bench structure of the new energy vehicle air conditioning compressor are connected, and compressed air can be used to check the air conditioning compressor 10.

[0042] In this embodiment, both the first sensing module 19 and the second sensing module 20 can be implemented based on conventional pressure and temperature sensors. The pressure and temperature data from the first sensing module 19 and the second sensing module 20 can be transmitted to the controller 15 and displayed on the operation panel 18, allowing the user to determine whether the air conditioning system is working properly and the refrigerant's operating status. For example, when testing the air conditioning compressor 10, the pressure values ​​on both the high and low pressure sides can be compared with the pressure range of a matching compressor model to independently determine whether the working pressure of the air conditioning compressor 10 is sufficient, thus preliminarily determining whether there is internal wear on the air conditioning compressor 10, achieving non-destructive internal testing.

[0043] In one possible implementation, a third sensing module 21 for detecting pressure and temperature is also included;

[0044] The detection end of the third sensing module 21 is located on the pipeline between the output end of the drying bottle 16 and the first input end of the expansion valve 13, and its data end is connected to the second data end of the controller 15.

[0045] In this embodiment, the third sensing module 21 is similar to the first sensing module 19 and the second sensing module 20, and can also be implemented based on conventional pressure and temperature sensors. By further configuring the third sensing module 21, the operating status of the air conditioning system and the refrigerant can be better monitored.

[0046] In one possible implementation, the first sensing module 19, the second sensing module 20, and the third sensing module 21 all include a pressure sensor and a temperature sensor.

[0049] In this embodiment, the rectifier-step-down module 22 can be implemented based on a conventional rectifier transformer and step-down module. It can provide the transformed and rectified DC high voltage to the air conditioning compressor 10, and the further stepped-down DC low voltage to the controller 15, the first sensing module 19, the second sensing module 20, the third sensing module 21, etc.

[0050] In one possible implementation, an air switch 23 is also included, which is located at the input of the rectifier-step-down module 22.

[0051] In this embodiment, the air switch 23 is a conventional model.

[0052] In one possible implementation, it also includes a vehicle computer 24, a first fan 25, and a second fan 26;

[0056] In this embodiment, the vehicle computer 24 is a conventional model, and the first fan 25 and the second fan 26 can be conventional blowers or fans.

[0057] In one possible implementation, the air conditioning compressor 10 is provided with a mounting base 101 at its bottom.

[0058] In this embodiment, by setting a fixing base 101, it is easy to fix the air conditioning compressor 10 on the vehicle or other test platform, so as to ensure that the air conditioning compressor 10 remains stable when working.

[0059] In one possible implementation, a WiFi module 27 is also included, whose communication terminal is connected to the second communication terminal of the controller 15.

[0060] In this embodiment, the WiFi module 27 can be a conventional model. The controller 15 can wirelessly connect to remote servers, computers, mobile phones, etc., through the WiFi module 27.

[0061] In one possible implementation, the first connecting valve 12 and the second connecting valve 14 are three-way valves.

[0062] In this embodiment, both the first connecting valve 12 and the second connecting valve 14 are three-way valves. One end of the three-way valve can be connected to the air conditioning compressor 10, and the other two ends can be used to connect the air conditioning refueling machine 28 and the integrated charging and suction air pump 29, respectively.
