"My good days are coming. ”
Yesterday, I went downstairs to buy groceries, and I met the owner of the home appliance repair next to the vegetable store chatting here. He lamented that his good days were coming, repairing refrigerators in the spring and air conditioners in the summer, and he could make a lot of money right away.
I can understand why spring is the peak period for refrigerator repairs? The boss explained to me that many people use the wrong refrigerator in winter, and it happens to be bad in spring.
Later, after learning that Xiao Yuan was a home blogger, he was very cautious, and told me "don't tell others". Xiao Yuan is such a sincere person that he turned around and made his "secret" public.
Error 1: Power off
The refrigerator cannot be turned off when it is plugged in
In winter, the outdoor temperature is not high, and many people unplug the power supply of their refrigerators in order to save electricity. But have you ever wondered: why doesn't the refrigerator make a switch like other appliances?
It's because the refrigerator can't be powered off! There is refrigerant in the refrigerator, and the refrigerant is corrosive to the pipes.
• The refrigerant of the new refrigerator is completely hidden in the compressor, so it will not break for a long time.
• The refrigerant will enter the pipes when the electricity is applied, but as long as the electricity is plugged in, the compressor will send the refrigeration oil to the pipes. It's still safe with a film of oil.
• When the power is off, the refrigeration oil will lose power and flow back into the compressor. At this time, the metal pipe will be directly exposed to the refrigerant, which will cause the pipe to be damaged and the refrigerant to leak after corrosion.
"The new refrigerators now use R610 refrigerant, which has much worse corrosion capacity than the previous R22, so the failure rate of power failure has also been reduced a lot. However, for safety reasons, it is still not recommended to cut off the power. 」
To save electricity, you can minimize the amount of storage in the refrigerator and leave the refrigerator empty. (It's not that the power can't be cut off completely, but the power outage time should be as short as possible, generally not more than a week.) ）
Mistake 2: Not adjusting the temperature
The cooler the temperature, the cooler it gets
Many people's refrigerator temperature control panels at home are completely furnishings, and they have never adjusted the set temperature of the refrigerator. It doesn't matter in the summer, at most it will cost a little electricity, and in the winter, if the temperature is not adjusted, it is likely to be damaged.
• If the temperature is not adjusted, there may be a situation where "the outside of the refrigerator is colder than the inside of the refrigerator". At this point, the refrigerator will stop working. Not only will there be problems that may arise from the above-mentioned "power outages", but it will also cause the freezer to be not heated enough, causing the food to melt and rot.
The correct way to adjust the temperature is:
The set temperature of the refrigerator, especially the refrigerator temperature, should be at least 2°C lower than the room temperature. For example, if the room temperature is 5°C, the set temperature should not exceed 3°C. If the temperature is controlled by the knob, the set temperature should be adjusted to the lowest in winter, usually 5 or 6 gears.
I. Some people have heating at home, or the outside is not very cold, and the room temperature will not be lower than 12 °C, so they can ignore the problem of temperature regulation.
II. Some refrigerators have a "winter compensation" function, which is actually to heat the refrigerator thermostat, so that the refrigerator mistakenly thinks that the room temperature is very high, and then work. This function is more power-intensive, and it is not recommended to turn it on when the room temperature is not lower than 2°C.
Mistake 3: No heat dissipation
Too cold or too hot will not work
In the case mentioned earlier, "the room temperature is too cold for the refrigerator to work", and the opposite is true, "the environment is too hot for the refrigerator to work properly".
In winter, there is always some heating equipment at home, and many people put the refrigerator next to the heating equipment. For example, put the radiator in the refrigerator, or put the electric heater next to the refrigerator.
These practices will cause the temperature near the refrigerator to be too high, which will affect the heat dissipation of the refrigerator:
The heat dissipation of the refrigerator is not good, which can lead to an increase in power consumption, or a non-stop refrigerator and great wear and tear on the compressor.
A special reminder - now some refrigerators are built-in, and the radiator is mounted at the bottom. The heat dissipation conditions of this refrigerator are already poor, and if you encounter floor heating pipes again, it will be really worse.
Therefore, users who use built-in refrigerators must confirm one thing: touch the floor at the bottom of the refrigerator with their hands to make sure that there are no floor heating pipes here before putting the refrigerator on it.
