What are the common methods for refrigerant leak detection

　　【】Visual inspection of leaks

　　 When oil traces are found somewhere in the system, this may be a leakage point.

　　 Visual leak detection is simple and easy, no cost, but it has big defects. Unless the system suddenly breaks and the system leaks a large leak point, and the system leaks liquid colored media, the visual leak detection cannot be located.

　　 soapy water leak detection

　　 fill the system with 10-20kg/cm2 pressure nitrogen, and then apply soapy water to each part of the system. The bubbling point is the leakage point. This method is currently a common leak detection method in roadside repair shops z*, but people’s arms are limited, and people’s eyesight is limited, and in many cases no leaks can be seen at all.

　　Nitrogen water leak detection

　　 Fill the system with 10-20kg/cm2 pressure nitrogen, immerse the system in water, the bubbling point is the leakage point. This method is essentially the same as the previous soapy water leak detection method. Although the cost is low, it has obvious shortcomings: the water used for leak detection is easy to enter the system, causing the materials in the system to be corroded, and the high-pressure gas may also cause damage to the system. Large damages and labor intensity during leak detection are also high, which increases the cost of maintenance and repair.

　　 Halogen lamp leak detection

　　 Ignite the leak detection lamp and hold the air tube on the halogen lamp. When the nozzle is close to the system leakage, the flame color changes to purple blue, that is Indicates that there is a large number of leaks here. In this way, open flames are generated, which is not only dangerous, but the combination of open flames and refrigerants will produce harmful gases, and it is also difficult to accurately locate leaks. So almost no one uses this method now. If you can see it, it may be in the stage of non-civilized society.

　　Gas differential pressure leak detection

　　Using the pressure difference inside and outside the system, the pressure difference is amplified by the sensor, and the leak detection result is expressed in digital, sound or electronic signals. This method can only qualitatively know whether the system is leaking and cannot accurately find the leak point.
