In the impression of refrigerators, refrigerators are the most worry-free electrical appliances. As long as they are plugged in, they will work 24 hours x 365 days without much setup and maintenance.
However, this impression is wrong. The refrigerator is not so "behaved". In winter, if the ambient temperature is relatively low and a small switch inside it is not turned on, it will become "lazy". Long periods of non-working will cause the food stored in the freezer to deteriorate.
This small switch is the temperature compensation switch in the refrigerator. If your refrigerator is not intelligently temperature-controlled, you may need to open it manually. Below, I will give you a detailed introduction.
What is the function of the temperature compensation switch of the refrigerator?
The so-called temperature compensation switch, as the name suggests, it is used to enable the temperature compensation of .
Some friends may ask, don’t all refrigerators like low temperature? Why do we need to perform temperature compensation?
This is the crux of the problem!
The refrigerator keeps food fresh in an environment where the refrigeration reaches a low temperature. In principle, the heat inside the refrigerator is transported to the outside of the refrigerator. According to reason, the lower the external environment temperature, the easier it is to transport the heat. In fact, this is indeed the case. When the ambient temperature of the refrigerator is relatively low, when the temperature is generally below 10°C, the refrigerator's temperature control system will not start the compressor for cooling when the temperature is low, or the frequency is low. Start refrigeration. In this case, the refrigerator freezer originally needs a low temperature of -18°C to keep the food fresh, but the compressor does not start the refrigeration, so the temperature of the refrigerator freezer will increase, which will cause the frozen and fresh food to lose freezing, affecting its The fresh-keeping effect, even the spoilage, causes losses to people.
In order to solve this problem, a method adopted by the refrigerator is temperature compensation.Electric heating is used to make the temperature control system mistakenly believe that the ambient temperature is rising, and start the compressor for cooling to maintain the normal fresh-keeping temperature of the refrigerator. This temperature compensation is not required at all times, but only when the ambient temperature of the refrigerator is relatively low, so set a switch, which is what we call a temperature compensation switch.
This temperature compensation switch, some early refrigerators, most of them are manual, in the winter is relatively cold, when the refrigerator is in an environment of 10 ℃ or below, you need to manually open it, and in other In season, the refrigerator needs to be turned off when the ambient temperature is relatively high. Nowadays, some smart refrigerators , some advanced refrigerators, also have similar temperature compensation, but they have realized intelligence and do not need to be operated by people.
This is the function of the refrigerator temperature compensation switch and the meaning of its existence. But I want to remind everyone that the temperature compensation function can solve a big problem, but it should be noted that the ambient temperature of the refrigerator will not be lower than 10 ℃ all the year round, and there is no need to turn on this temperature compensation switch.
Precautions for using the refrigerator in winter
When using the refrigerator in winter, in addition to the temperature compensation switch mentioned above, in order to use the refrigerator, you should also pay attention to the following matters:
1. Pay attention to adjusting the temperature of the refrigerator
Refrigerator in winter, the ambient temperature is relatively low, even if the temperature compensation is turned on, its start frequency is different from summer, and some refrigerators do not have temperature compensation function, so in order to prevent the refrigerator from not starting for a long time, the preservation temperature of the refrigerator is affected. , You need to set the refrigerator temperature lower. For example, in summer, it is recommended to switch to gear 3 or gear 4. In winter, it is recommended to switch gears to gear 5 or 6. The specific setting depends on the ambient temperature. The lower the ambient temperature, the lower the refrigerator temperature should be set. Worry about freezing in the refrigerator, dry in winter, the refrigerator is not easy to freeze.
2. Be careful not to leave the refrigerator unused.
In some colder areas, the outdoor itself is a natural refrigerator, so the refrigerator is left unused in winter. In fact, this is not good for refrigerators. In refrigerators that have been idle for a long time, the internal refrigerant is in a liquid state for a long time, which will easily cause corrosion to internal pipelines and compressors, thereby affecting the service life of the refrigerator. Therefore, the refrigerator is not used much in winter, and it is also recommended to turn on the electricity daily to let it run, or simply put it in a heated room for use, and try not to leave the refrigerator idle.
Summary
Refrigerator is a large electrical appliance, its use is not what we imagined, just plug in the electricity, and don’t care. To make good use of the refrigerator, we should still have some knowledge about using it. The article mainly introduces some knowledge of the temperature compensation switch of the refrigerator and two precautions for using the refrigerator in winter. I hope everyone can use the refrigerator correctly, so that it gives us convenience in life, not trouble.
