The compressor of the refrigerator is the heart of the refrigeration system, and its quality will directly affect the performance of the refrigerator. Therefore, in the process of testing the quality of the refrigerator compressor, it is necessary to focus on the detection of the old and new compressors and their operating conditions.
We can check the freshness of the compressor from the appearance, including the appearance, production date, sound and temperature.
1. Appearance
The brand new refrigerator compressor is usually smooth in appearance, bright in color and not rough. The weld junctions of input and output pipes are directly welded with the evaporator at one time. If they are re welded, there will be traces of grinding.
2. Production date label
All new compressors have nameplates on which the model, number, date of manufacture, power, etc. of the compressor can be checked.
3. Sound
When the compressor starts to rotate, there will be no mechanical noise. With the increase of operation time, the compressor will make a clear, balanced and stable running sound, and the sound will slowly decrease. When the compressor is stopped, it will not make abnormal sound.
4. Temperature
When the compressor is running, touch its shell with the back of your hand, and the shell will be too hot.
