Can the refrigerator be plugged in immediately after it is unplugged? Please, 3Q

The refrigerator power plug is not easy to unplug at will. When the temperature in the refrigerator drops to a certain value, the thermostat will automatically cut off the power supply. At this time, the pressure of the refrigerant is already very low, which is small compared to the load compressor of the motor, and the motor is easy to start normally.

If the power supply is forcibly cut off, and the power supply is immediately turned on when the refrigerant has a fairly high pressure, the high voltage force causes the motor to be overloaded, and the starting current is large, about 15 20 times the normal value, and it is easy to burn the motor. Therefore, do not unplug the refrigerator power plug at will. When the power must be cut off, it should also be reconnected 5 minutes after the power is off, and the power should be turned on immediately after the power is not off.

It is best to wait a few minutes for the compressor line pressure to drop some before starting is good for the refrigerator compressor.

The refrigerator can be plugged in after 1-2 hours after unplugging.

The refrigerator can be powered off, but not for too long.

If the refrigerator is not used for a long time, it is no problem to cut off the electricity for 2-3 months, but if it is too long, the refrigerator may break. At present, most of the iron pipes used in refrigerators, in a humid environment, the iron pipes are easy to rust, although the heat sink part has protective paint, but there is also the possibility of rust.

If the refrigerator is powered on, the heat sink is hot, and the water vapor is not easy to gather, so the iron pipe is not easy to rust. If the refrigerator is interrupted for a long time, there is no lubrication of refrigeration oil in the pipeline, and the pipe is easy to be slowly corroded.

At the same time, experts point out that if the refrigerator is stopped in winter, it will have a negative impact on the service life of the refrigerator. The refrigerator will not be used for a long time, and the refrigeration oil and refrigerant will be deposited at the bottom of the compressor and the bottom of the pipeline, but the refrigerant has a corrosive effect, and the refrigeration oil can play a good neutralizing role.

If it is left for a long time, the refrigerant will speed up the corrosion of the lines due to the lack of refrigeration oil, which will cause damage to the refrigerator. In addition, the refrigerator is easy to jam the cylinders and pistons inside the compressor if it is left for a long time.

In fact, the temperature is low in winter, and the temperature inside the refrigerator drops down after a while of running, and it consumes much less electricity than in summer. Refrigerator shutdown does not save much electricity, and if the refrigerator breaks down because of this, it is not cost-effective. In addition, from the perspective of hygiene, although the temperature is relatively low in winter, it is not stable enough, and the preservation effect on food is still not as good as that of the refrigerator.

There is no one specific set answer to the question of how long it takes to plug in the refrigerator after unplugging it, as the time it takes to plug it in depends on several factors:

1.Storage time of frozen food: If the frozen food has been thawed or is being thawed, plug it in as soon as possible to prevent the food from spoiling. If the food still remains frozen, plugging in the power can be delayed slightly, but it is still recommended to restore power as soon as possible.

2.Temperature inside the refrigerator: The temperature inside the refrigerator increases over time. If you wish to keep the food in your refrigerator fresh and safe, plug it in as soon as possible to allow it to cool down and return to its normal operating temperature.

3.Type and size of refrigerator: Different types and sizes of refrigerators will vary in the time it takes to return to the normal operating temperature. Large refrigerators typically take longer to cool down, while small refrigerators may take faster.

4.Ambient temperature: If the ambient temperature is high, it will take longer for the refrigerator to lower the temperature and reach the ideal working condition. In hot summer months or in a hot environment, it is recommended to plug in the power supply as soon as possible.

5.The amount and density of food in the refrigerator: If there is a large amount of food in the refrigerator or the density of the food is high, it will take longer for the refrigerator to cool down and return to normal working condition.

Summary: In order to ensure the freshness and safety of food, as well as the proper functioning of the refrigerator, the time to plug in the refrigerator should be as soon as possible. Taking into account factors such as the state of the food, the type and size of the refrigerator, the ambient temperature, and the burn-up and density of the food, it is reasonable to assess how long it will take to plug in the power supply to ensure that the refrigerator can quickly return to ideal working condition.

1. Plug in the refrigerator in the morning and unplug it at night, although it can save electricity, but it is a bad habit, because the temperature is high when the shutdown is high, and the food residue left in the refrigerator is easy to ferment, acidify and corrode the metal parts in the box.

2. The refrigerator evaporator is made of aluminum, so there are copper and aluminum joints in the refrigerator refrigeration pipeline. Powering on during the day and powering off at night will accelerate the "electrochemical" effect of copper and aluminum joints due to the relatively high temperature, and it is easy to leak faults.

3. The refrigerator evaporator is made of aluminum, with coil type and blowing type. Blowing evaporators (especially old refrigerators) are prone to "blow-by" faults due to the increase in system pressure after the power failure at night, which affects refrigeration.

4. There is refrigeration oil in the compressor for the compressor to lubricate. The refrigerator is often powered on during the day and cut off at night, which will cause the refrigeration oil to precipitate, and the long-term power-on and power-off operation will affect the lubrication of the compressor and affect the service life.

Don't do it. Once the refrigerator is plugged in, it should not be unplugged all year round. Unless there is an unexpected power outage, there is no way to do anything.

You plug it in and unplug it in a while. This will not save electricity. It also costs electricity.

What's even more terrible is that it is easy to damage your refrigerator, and some people just don't understand it and often unplug it like this. In order to save electricity, I ended up damaging my refrigerator.

It is recommended that you turn on the power of the refrigerator for a long time to save more power. If you turn on and off the refrigerator frequently, not only can you not save electricity, but also the refrigerator. There is severe damage, which can make the refrigerator completely inoperable.

Nowadays, refrigerators are all thermostatic refrigerators. After reaching the temperature, it will automatically shut down and work at a constant temperature, basically the power consumption is very low, and it has nothing to do with you turning off the power. Therefore, it is recommended that you turn on the refrigerator and do not turn off the power of the refrigerator under normal circumstances.

This is more power-efficient and better for the refrigerator.

Hope mine is helpful to you, hope.

Your method is not advisable. The thermal insulation means of the refrigerator can not be done in an ideal state, when the power is off, the outside environmental temperature will gradually increase the temperature inside, for a long time, it will lead to the increase in food temperature, bacterial multiplication, resulting in food spoilage, the role of tiny bacteria is not negligible, your refrigerator will lose the value of low temperature preservation, only low temperature can make bacteria inactive, always turn on the power supply, rely on the detection and control of the temperature controller of the refrigerator, in order to ensure that the compressor will always control the temperature in the low temperature environment, You can't shut down to save power, it's not worth the cost.

In this way, you can only waste electricity, there is a thermostat inside the refrigerator, it will not run when it reaches the set temperature, the refrigerator will gradually increase in temperature after you turn off the power, and the refrigerator will run for a long time after the power is turned on, which will have an impact on the food in the refrigerator, and it will also have an impact on the compressor.

Do not unplug the power supply in order to save a little electricity, which will affect the normal service life of the refrigerator, if you just want to save a little electricity bill, then stop the refrigerator directly.

The refrigerator seems to be treated like this, and it seems that there is no electricity for half a day, "saving electricity bills"? In fact, the refrigerator is down for a long time, and it takes longer to restart the refrigeration to the predetermined low temperature, which means that more electricity is required, and besides, after unplugging the power, the temperature of the refrigerator continues to rise, and if the room temperature is high, the problems with the things stored inside are even more than worth the loss. It is better to adjust the refrigeration temperature to a slightly higher temperature when the room temperature is higher.

If the compressor is working when the power plug is unplugged, it must take about 3-5 minutes to reconnect the power supply, because after the compressor has just stopped, the pressure difference between the high-pressure pipe and the low-pressure pipe is very large, and the power supply can not start to work at this time, which will cause the working current of the compressor motor to increase sharply, the temperature will rise sharply, and even lead to burning, so the compressor is equipped with a thermal protector to protect the compressor motor from being burned. After 3-5 minutes, the pressure difference between the two ends slowly returns to equilibrium, and then the power is turned on, and the compressor can start working smoothly.

If the compressor is not working, after unplugging the mains, you can turn on the power at any time without problems.

Most of today's ** refrigerators are equipped with time-delay protection circuits, so there is no such problem.

At least three minutes, no overcurrent damage to the compressor.

20 to 30 minutes at start, good for the refrigerator.
