The single-door refrigerator is now very common in daily life, but when people have problems with their own refrigerators, they don't know what to do with the refrigerators, and they don't know what to do with the refrigerators, so they'll show you how to fix the single-door refrigerators and help you to do it!
Freon refrigerants consist of halogen elements, and when halogens meet with burning copper, the flame becomes green or purple green, and when the amount of leakage varies from less or less to more, the colour of the flame changes correspondingly from slightly green to slightly green, so that the amount of the leak and the amount of leakage can be judged by the colour of the flame. The leakage method is to ignite halogen detection leaks and then detect the refrigeration component using the rubber pipe of the probe while observing the colour of the flame, which can easily identify the leak point and determine the amount of leakage。
Leakage is used mainly for the detection of hazardous components such as refrigerator compressors, evapotors, condensers, etc. Helium or dry air, which is filled with 0. 8-1ma in the leaked component before detection, is then placed in warm water around 50°c, carefully observing whether there is a bubble or, if there is an air bubble, a leak. In case of leakage, the site should have sufficient light, the water should be calm and observation time should not be less than 1 min, and the inspection must be immersed below 200 mm。
The soap bubble detection is both convenient and safe and is widely used in maintenance by cutting the soap into pieces, immersing it in hot water, constantly mixing it so that it dissolves, cooling it to light yellow solution, not too thick, not too thin, not too thin to detect small leaks, not too easy to pick up bubbles, and when leaks are made with a veil, they are purified at the checkpoint, then sprayed around the checkpoint with clean brushes, and see if air bubbles are present。
Electronic halogens are mainly used for precision leak detection. In the event of a leak, the spot should be kept at a distance of 3-5 mm between the spot and the spot being detected, and the speed of movement of the spot (generally not exceeding 50 mm/s) should be maintained, allowing a general determination of the leak point and the amount of leakage, based on the leakage instrument reading and the sound from the humming machine. E-halogen detection leaks should be used to prevent large quantities of refrigerants from being inhaled, and care should be taken to detect environmental ventilation, preferably in fresh air。
Carefully observe whether the outer walls of the refrigeration system are oily, with careful observation of the evaporating aluminium tube and the copper pipe welding area, the internal walls of the evaporation unit, the high compressor, the low pressure tube interface, the dry filter entry and exit interface, etc. If the leak is not visible, you can put on white gloves or use white paper to contact the suspect, and if there is oil on the glove or white paper, that means there is a leak
With the above-mentioned mini-coding on how single-door refrigerators are to detect leakage of refrigerants in refrigerators, any malfunctions in the immersion area, and some minor maintenance techniques, the mini-coding believes that there are more or less harvests。
