Judging the pros and cons of the freezer compressor: a few drops of water in the evaporator can be confirmed to be ice within a few seconds, which means the compressor is very good
Turn on the power correctly, first open the cabinet door, turn the thermostat counterclockwise to turn off, and then turn the thermostat clockwise to the middle position when the internal lighting is turned on steadily, hear the sound of the compressor starting, turn off Cabinet door to observe the working status. Because this is the basic judgment of the compressor, it can be known whether the compressor of this freezer meets the requirements.

　　Identify the advantages and disadvantages of the refrigerator thermostat
　　 Then there is a thermostat, how to judge the temperature of the freezer, especially according to the season? First, the thermostat responds to the temperature in the freezer, which is proportional to the compressor running time. The thermostat is to convert the temperature signal into a mechanical displacement or electrical signal, compare it with the given temperature signal, and then adjust the running time of the compressor.
The comprehensive performance of the switch ratio judges that the constant temperature operation of the refrigerator is normal. If the cooling performance meets the standard, the longer the downtime, the longer the temperature is relatively stable, the better the insulation performance of the refrigerator. Through the above inspection, you can know how the temperature regulator is judged, so that you can choose a good refrigerator.

　　The judgement of the foam layer of the refrigerator
　　Because the foam layer is the insulation layer of the freezer, only if it is good, it can be kept inside the freezer to cool. Otherwise, cold air escapes and it is impossible to refrigerate food. Therefore, the quality of the foam layer is also important. If we recognize a good foam layer, we must try it by hand. A good foam layer is very hard, heavy in weight, has a fresh-keeping effect, and has better energy efficiency. Ou Xue Freezer uses the entire polyurethane foam, which not only has high strength and high density, but also safety, high energy efficiency and beautiful appearance.
　　In addition to the above points, our freezer evaporator and evaporator are also very important components. Its quality determines the cooling rate and freshness of the freezer. The Refrigerator has a completely cooled design, a large evaporative area copper tube, rapid cooling and fresh display.
