Embodiment Construction
[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0027] As mentioned in the background technology, the leak detection method of the pipeline system of the existing air conditioner is mainly manual detection, that is, the pipeline system of the air conditioner is filled with refrigerant, and then the inspector checks the solder joint structure of the pipeline system, etc. Check one by one. Although the existing manual leak detection method can detect the pipeline system of the air conditioner, the manual leak...

The invention discloses a leakage detection device for the pipeline system of an air conditioner. The leakage detection device comprises a seal box, an air evacuation pipeline which is communicated with the seal box, a vacuumizing device which is connected with the air evacuation pipeline, and a detection device which comprises a probe arranged in the air evacuation pipeline. The air conditioner is placed in the seal box. The pipeline system of the air conditioner is filled with a refrigerant. The detection device is used to detect whether the refrigerant is in the air evacuation pipeline. According to the technical scheme provided by the invention, after the air conditioner is placed in the seal box, the vacuumizing device is used to vacuumize the seal box; in the process of vacuumizing,if the refrigerant leaks out from the pipeline system and the refrigerant diffuses into the air evacuation pipeline, the refrigerant is detected by the probe of the detection device; and the leakage detection device provided by the invention replaces a manual leakage detection method, which ensures high leakage detection efficiency and avoids the problem of missed detection.
Description
technical field [0001] The invention relates to the technical field of air conditioner detection, and more specifically, to a leak detection device for a pipeline system of an air conditioner. Background technique [0002] With the development of science and technology and the continuous improvement of people's living standards, air conditioners have gradually become an indispensable part of people's lives and work. During the production process of the air conditioner and before leaving the factory, multiple tests are required, especially the leak detection test of the pipeline system of the air conditioner. The sealing of the pipeline system of the air conditioner directly affects the quality of the air conditioner. quality of the device. The existing leak detection method of the pipeline system of the air conditioner is mainly manual detection, that is, the pipeline system of the air conditioner is filled with refrigerant, and then the inspectors inspect the solder joint ...
