How to judge the quality of refrigerator refrigeration
2022-02-16
If the refrigeration effect of the refrigerator is good, there is naturally no problem. If the refrigeration effect is not good, it means that there is a problem with the refrigerator, or the temperature is not set properly.
Under normal circumstances, the temperature of the freezer compartment of the refrigerator should be lower than minus 18 degrees, while the temperature of the refrigerator compartment is between 1-10 degrees.
If the temperature in the refrigerator is within the above temperature range, it means that it is working normally. If it is too high or too low, the temperature in the refrigerator should be improved by adjusting the thermostat. If the temperature in the refrigerator cannot be improved by adjusting the thermostat, Indicates that there is a problem with the refrigerator working. Generally, the gear should be set at the middle gear in spring and autumn, lower in summer, and higher in winter.
The specific issues are as follows:
In winter, the indoor temperature is low, which often causes the compressor to not start automatically, resulting in the refrigerator not cooling or the cooling effect is not good. The winter temperature compensation switch should be turned on in time, and the thermostat (mechanical) gear should be properly adjusted. Some. If there is no temperature compensation switch, or the switch is damaged, the emergency treatment method is as follows: every day, in the morning, noon, and evening, at each time period, first adjust the thermostat (mechanical) to the highest level, and let the compressor start forcibly. , and then adjust the gear back to the position of the principle. Generally, the middle gear is slightly higher, so that 5-6 times a day can be adjusted regularly to ensure that the food in the refrigerator is frozen and kept fresh, and when the weather changes After warming up, the compressor will automatically start to work and cool down.
The refrigerator compressor always works but the cooling effect is not good. In this case, the pipeline is damaged and leaked, resulting in a lack of fluorine. The refrigerator evaporator has no frost or less frost, the problem of the condenser is low, and the temperature difference between the two ends of the compressor is relatively high. If it is small, the leak should be checked first, then plugged, and then vacuumed and fluorinated.
The refrigerator is good or bad when it is refrigerated. Most of it is caused by ice blockage. There is a lot of water in the pipeline, which causes the capillary or filter to freeze. You can use a hair dryer or electric soldering iron to heat the capillary and filter to melt the ice. Refrigerator If the fault occurs frequently, it is necessary to clean the pipeline, after drying, replace the filter, vacuumize and add fluoride.
The refrigeration effect of the refrigerator is not good, and the compressor is stopped and turned on. This situation is mostly caused by the dirty and blocked pipeline, and the pipeline should be cleaned.
In addition, the contact of the mechanical thermostat is stuck or the temperature sensing tube is damaged, loose and displaced, which will also cause the compressor to always work without stopping. However, the refrigeration effect of the refrigerator is good at this time, and the temperature in the refrigerator is too low. Check and eliminate step by step, if the temperature sensing head is damaged, it should be replaced with a new thermostat.
In addition, there is a problem with the compressor starter or thermal protector, or a problem with the compressor motor, which will also cause the compressor to not start to work.
