Description

Technical Field

[0001] The utility model relates to the technical field of subway air-conditioning unit testing, in particular to an air-conditioning unit testing platform. Background Art

[0002] With the rapid development of urban rail transit in my country, smart operations and intelligent O&M are becoming key priorities for major subway systems. As a core system of subway trains, the reliability of the air conditioning system directly impacts train comfort. Therefore, post-repair reliability and condition testing of air conditioning units are crucial for ensuring their reliability after installation. Currently, there is a lack of convenient testing equipment for air conditioning units after overhauls and overhauls, requiring only on-board testing to determine their condition. If an air conditioning unit malfunctions, the overhead line must be disconnected and reenergized for inspection and testing. Serious faults require the unit to be disassembled and returned to the factory for repair. Frequent power outages, unit disassembly, hoisting, and transportation, among other complex processes, waste manpower and material resources, as well as time and space. Therefore, a convenient offline air conditioning testing device is crucial for addressing the current challenges of post-repair condition testing of air conditioning units after overhauls and overhauls.

[0003] For the testing device of the air-conditioning unit, reference patent number: CN219284692U, an air-conditioning unit performance test bench, this air-conditioning unit performance test bench has a simple structure, novel design and high testing efficiency.

[0004] However, the above air-conditioning unit testing device is only used for testing the air-conditioning unit, but does not have the function of wind pressure testing. Therefore, it is impossible to conduct safety testing experiments to determine whether the wind pressure generated by the force of the subway's movement will affect the normal operation of the air-conditioning unit at the installation location of the air-conditioning unit in the subway.

[0005] For this purpose, we propose an air conditioning unit test bench. Utility Model Content

Therefore, for the air-conditioning unit installed in the subway, whether the wind pressure generated by the force of the subway running will affect the normal operation of the air-conditioning unit and the safety test experiment cannot be carried out.

[0032] Example 2

[0033] See also Figure 1-Figure 3 Based on the first embodiment, the present invention provides a technical solution:
