I once asked a home appliance repair master, and he said that winter and spring are their peak seasons every year. Especially in spring, almost all orders received are for refrigerator repairs.
In the final analysis, most people do not know the correct way to use the refrigerator. It's cold in the refrigerator, and it's also very cold in winter, but when the refrigerator encounters winter, many problems often occur. Today, let’s talk about how to make the refrigerator survive the winter safely - the points of attention for new refrigerators and old refrigerators are different ~
New refrigerator
When you buy a new refrigerator home, remove the packaging and place it in the designated position. After adjusting the level of the four legs, do not turn on the power first. Do the following three things before it can be used normally.
1. Leave it alone
The new refrigerator needs to be left alone for a period of time. This is because there is refrigeration oil in the refrigerator. Refrigeration oil has two functions: lubrication; anti-corrosion.
Under normal circumstances, the refrigeration oil should be in the compressor . When the compressor works, it will drive up the refrigeration oil, allowing the refrigeration oil to fill the entire refrigerator pipe (metal pipe).
During the transportation process, the refrigerator will tilt, causing the refrigeration oil to leave the compressor. If the power is turned on again at this time, the compressor will not get enough lubrication and is prone to wear and even direct damage. The pipes are not protected by the oil film and are easily corroded by the refrigerant.
So we have to let the refrigerator sit for a while after moving it, waiting for the frozen oil to flow back into the compressor.
Standing time: 8 to 12 hours in summer; in winter, the refrigeration oil will solidify and the reflux speed is slow, so it needs to stand for more than 24 hours.
2. Open the door
While the refrigerator is standing, we should not be idle and do two things.
The first is to open the refrigerator door and "disperse" the refrigerator . The refrigerator is not like a wardrobe, the smell is not that big, but it still smells more or less. If you don’t want your food to become a deodorizer, remember to do a good job of deodorizing it.
The second is cleaning the refrigerator . The refrigerator has not been cleaned since it came out of the factory. Therefore, necessary dust removal and disinfection work must be done well, after all, it is something that comes into contact with food.
3. After the unloaded
is completed, don’t rush to use it. Plug in the refrigerator first and let it work for a while.
The internal temperature of the new refrigerator is relatively high and requires cooling for a long time. If you put something in the refrigerator at this time, it will increase the workload of the refrigerator and extend the working time of the refrigerator.
For a refrigerator that is working for the first time, long-term operation will cause serious fever. At this time, not only will there be greater wear and tear on the compressor, but it will also cause a surge in power consumption.
When the refrigerator is shut down for the first time, you can put food in it. The initial temperature of is low in winter, and it only takes about five or six hours. In summer, the initial temperature is high and it takes more than eight hours to shut down.
The old refrigerator
The old refrigerator can always be used normally, right? The result is disappointing again - there are three things you should pay attention to when using an old refrigerator.
1. Don’t cut off the power
Old refrigerators cannot cut off the power . There are two main reasons:
The first is the problem of the refrigeration oil. After the power is cut off, the refrigeration oil will flow back into the compressor. The refrigerant will directly contact the pipes. If you use it again the next year, you will find that the pipes are leaking and the refrigerant has escaped.
Refrigerators without electricity do not have this to worry about, because the refrigerant in new refrigerators is hidden in the compressor. Refrigerant only enters the pipes when power is applied and cannot be recovered again.
The second is that refrigeration oil that has been used for a long time will become dirty and its viscosity will increase. When the power is cut off at this time, all the oil will accumulate in the compressor and wrap the piston inside. After a winter of precipitation, it will become more viscous.
If the power is turned on again in the coming year, the compressor will fail to start due to too much resistance, causing cylinder explosion.
2. Adjust the temperature
In winter, you need to adjust the temperature to the lowest - I am right, the colder the weather, the lower the set temperature of the refrigerator should be.
This is because there is a sensor inside the refrigerator.When the internal temperature of the refrigerator is higher than the set temperature, the refrigeration work will be started; otherwise, it will remain shut down.
The weather is cold in winter, and the room temperature is likely to be lower than the set temperature. At this time, the refrigerator will not cool down all the time, causing the ice cubes in the freezer to melt.
Of course, many places now have heating. If the temperature in the room is above 10°C, there is no need to adjust the refrigerator set temperature.
3. Clean the refrigerator frequently
What is the best way to save energy? The answer is to give it to reduce some of the load on - the food in the refrigerator is its load.
In winter, the indoor temperature is relatively cool, so there is no need to put many foods in the refrigerator.
There are also some packaged foods. If they are not opened, they do not need to be stored in the refrigerator.
direct cooling refrigerator , there will be frost in the freezer. Frost not only takes up space and is dirty, but also becomes a load on the refrigerator. Therefore, regular cleaning of frost can also achieve the purpose of saving electricity.
