Why is the leak detection of the soap foam of the chiller inaccurate?

First, the concentration of soap foam.

When using soap foam for leak detection, it is necessary to consider the concentration and other aspects. Generally speaking, not many people know how to control the concentration of soap foam. If the concentration of the soap foam is too strong, the leakage point will be difficult to find. This is because the soap foam will not flow, and if it is too thin, the leakage point may not be found!

Second, the performance of the soap foam when it finds the leak is not obvious.

Soap foam leak detection, when the soap foam finds the leak point, it may not be able to be very obvious. Due to the concentration of the soap foam or other problems, the leak point has been detected but cannot be found.

Third, the soap foam may cause corrosion.

Soap foam may have a certain corrosive effect on the refrigerant pipeline, this also needs attention, and it may not be easy to clean up when cleaning!

Fourth, the leak detection of soap foam depends on individual ability.

The success of using soap foam for leak detection mainly depends on personal ability!

Fifth, compared with professional leak detection methods such as vacuum leak detection, pressure leak detection, and leak detection by leak detectors, soap foam leak detection is a bit of a “child’s play”.

Yes, the real and professional leak detection method is to use vacuum leak detection method or pressure leak detection method, as well as professional halogen leak detection instrument, electronic leak detection instrument, etc., to conduct leak detection. These freezer leak detection methods are more professional , And the accuracy rate is relatively high. Although the operation is relatively complicated, the process is relatively strong. Anyone can master it through simple learning, and the accuracy of leak detection is not determined by “craftsmanship” or experience. It is determined by the equipment and process, so it is very reliable.
