What should I pay attention to when buying a second hand refrigerator? 20

Second-hand home appliance experts advise how to buy refrigerators.

First listen to two things: one listens to the operating noise of the compressor should be very small, if there is a relatively large noise and the machine swings, it means that the compressor has been aged and is not wanted.

Second, listen to the "sound of running water": put your ears against the wall of the freezer and open the machine to listen carefully, if you hear the sound of flowing water, it means that the air running inside is stable, if you hear the sound is short, it means that there is little air or there is a leakage.

Look again, turn the machine on, put the temperature controller in the middle of 3 to 4, and see if the temperature reaches minus a few degrees (full of frost) The machine will stop, otherwise the temperature controller is not good, a waste of electricity, roughly that's all, it's best to find an experienced one to go together, so as not to suffer.

Also pay attention to whether the refrigerator has any bacterial infections

1.Do not buy a refrigerator that does not refrigerate and leak refrigerant.

Freon refrigerators that are dry and have poor refrigeration capacity cannot solve the problem by adding fluoride. The key is that the refrigerator has internal leaks to solve, and the maintenance cost is very high. Currently, refrigerators do not use copper pipes as radiators and evaporators.

Instead, pure aluminium tubes or bondi tubes are used. Aluminum and steel pipes are prone to rust and wear after 5 to 8 years of normal use, resulting in internal leakage and loss of refrigerant freon. In the past, copper pipes such as Rongsheng and Haier were used as radiators and evaporators, and the copper pipes would not rust for 10 to 20 years.

2.Try to buy one.

For large double-door refrigerators with primary and secondary energy efficiency, the working current of the refrigerator is measured with an ammeter: large refrigerators with a capacity of more than 180 liters and more than two doors are suitable for more than 3 people. The primary energy consumption current is, the secondary energy consumption current is, and the tertiary energy consumption current is, so it is recommended not to purchase the first.

Four or five times energy consumption. 100-170 liter double door refrigerator compressor.

The energy consumption ratio is not much different, and the current is not large, but the compressor has a short running time and a long downtime, which is suitable for 2 people and less than 2 people. A 50-60 liter single-door refrigerator is not recommended. Freezer.

Less, the evaporator is plate type, which is easy to break.

3.It is the most cost-effective to buy a second-hand refrigerator with copper tubes, with guaranteed quality and high refrigeration efficiency. in heat conduction.

In terms of copper, copper is the best, aluminum is medium, and steel is the worst. In the event of a failure, the cost of copper will be higher.

4.Cooling effect. Be sure to pay attention to whether the refrigerator is cooling well.

An easier way is to power the refrigerator for half an hour to see if the refrigerator is cold and the evaporator is frosted evenly. Don't buy it on the spur of the moment because it looks new. At the same time, check the tightness of the refrigerator door.

If you find that the refrigerator door is not tight, do not buy it.

5.Compressor. The operating noise of the compressor should be very low. If the noise is loud and the machine is swinging, it means that the compressor has aged and cannot be used; In addition, you can put your ears close to the wall of the refrigerator and turn on the machine to listen carefully.

Be sure to pay attention to the power of the side liquid, pay attention to the material and brand of the refrigerator, pay attention to the freon in it when buying the refrigerator, be sure to pay attention to the effect of freezing, and pay attention to the power consumption and power consumption of the goods.

We must pay attention to the quality of the liquid car, and we should also pay attention to the problem of cost performance, and then we should also bury the stool to choose an energy-saving and environmentally friendly refrigerator and observe the use of the refrigerator.

Be careful of the quality, because it is second-hand, people have been using it for a long time before, and you must choose a quality one.

Be sure to pay attention to the cleanliness of the refrigerator as well as the power issue, and you should also pay attention to the cooling of the refrigerator, because these are very important.

Summary. Hello, I don't recommend buying second-hand refrigerators, because second-hand refrigerators on the Internet or in reality are basically not used by others, but later refurbished, and then replace some of the equipment in these second-hand refrigerators, and then take them to the market to sell. However, second-hand refrigerators like this generally break down relatively quickly, so it is not recommended to buy, and it will break down within a few months of purchase and use, which is not worth it.

Can you buy a used refrigerator?

Hello, I don't recommend buying second-hand refrigerators, because second-hand refrigerators on the Internet or in reality are basically not used by others, but later refurbished, and then replace some of the equipment in these second-hand refrigerators, and then take them to the market to sell. However, second-hand refrigerators like this generally break down relatively quickly, so it is not recommended to buy, and it will break down within a few months of purchase and use, which is not worth it.

I would like to ask, I bought a second-hand refrigerator today, and it was broken when I bought it.

I would like to ask, I bought a second-hand refrigerator today, and it was broken when I bought it.

Dear, you buy back this second-hand refrigerator, if it is broken, you can return it directly, and then go behind you and let the merchant compensate you.

This requires you to find the merchant of the second-hand refrigerator you bought, and then return it.

1. Look at the traces of maintenance. Look at the inside and outside of the refrigerator for signs of repair, especially pay attention to whether the compressor has been opened. Repaired refrigerators have a higher chance of breaking down again, so check them carefully and don't buy them impulsively when you see a newer look.

2. Look at the refrigeration effect. The simple way to do this is to power up the refrigerator for half an hour to see how well the freezer freezes and the evaporator.

Frost condition. A better quality refrigerator freezes faster and frosts evenly.

3. Check the airtightness of the refrigerator door. The refrigerator is not airtight enough, the cold air is easy to run away, and the refrigeration effect is not good. Too much hot air enters the refrigerator, which can easily cause water accumulation in the refrigerator. If you find that the refrigerator door is not tight, try not to buy it.

4. Listen to the sound of the compressor. The normal compressor operation noise is very small, if there is relatively large noise and the machine oscillates, it means that the compressor has been aged. In addition, if you put your ear against the wall of the freezer, if you hear the sound of flowing water, it means that the qi running inside is stable; If the sound is short, it means that there is little air or there is air leakage.

5. Look at the startup time. Generally, the refrigerator will be turned on every 5 to 10 minutes, and if the refrigerator is started too often, it will consume a lot of electricity.

The general life of a refrigerator is 10 years, and the life of a refrigerator is determined by the quality of its own brand and whether the user has carried out proper maintenance.

After the Spring Festival, I feel that the temperature is rising so fast, and it will gradually heat up in a few months, but now some consumers want to buy a refrigerator for use because of limited limits, so buying second-hand refrigerators has become their choice. So the question is, how to choose a second-hand refrigerator, what are the precautions for buying a second-hand refrigerator, do you know? Let's take a closer look.

1. How to pick a second-hand refrigerator.

1. Choose a brand.

There are many common second-hand refrigerator brands on the market at present. When buying second-hand refrigerators, you should try to choose trustworthy brand products, which are relatively more stable in quality. Try to buy second-hand refrigerators with Class I and Class II energy efficiency.

2. Appearance identification.

Even if you buy a second-hand refrigerator, you need to take a closer look at the appearance of the product: is the overall structure of the product intact? Are there any serious rusts or bumps?

Is there any trace of refurbishment or counterfeiting in the appearance of the product? Only more detailed inspection can avoid buying counterfeit or poor quality products.

3. Look at the maintenance traces.

If the refrigerator has obvious signs of repair, especially if the compressor can be seen to have been opened, do not buy such a second-hand refrigerator. Whether the solder joints of the compressor smile have been re-welded, as long as they are moving, they can be seen quickly, and they can also be touched, which is relatively rough and not as smooth as before.

4. Look at the refrigeration effect.

Be sure to pay attention to whether the refrigeration effect of the refrigerator is good, the simpler way is to power on the refrigerator for half an hour to see if the refrigerator is all cooled down and whether the evaporator frost is even. Don't buy impulsively just because it's newer.

5. Listen to the noise of the refrigerator compressor.

If the noise is relatively loud and the whole refrigerator is swinging before the operation touches, it means that the compressor has aged and should not be purchased. The general refrigerator compressor will start every 5-10 minutes, if the refrigerator you look at starts too often, it also means that there is something wrong with the compressor of this refrigerator, and do not buy it.

2. What are the precautions for buying a second-hand refrigerator?

When buying a second-hand refrigerator, you need to check whether the refrigerator can be used normally, some second-hand refrigerators are still in the three-year warranty period, and some refrigerators have passed its warranty period. The second-hand refrigerator purchased in the second-hand home appliance market usually does not have a warranty, so it can be said that the second-hand refrigerator is not *** after purchase, which means that there is a problem after use, and you have no place to appeal.

1. The closure of the door has a certain magnetic force due to the magnetic door strip of the door door, so a certain tension force must be applied when opening the door to pull it apart, and the door will be automatically closed due to the suction of the magnetic strip when the door is close to the door frame when the door is closed. 2. The refrigerator with good starting performance can start running when the power is turned on. 3. When the compressor is running with running noise, the refrigerator will tremble slightly, and the operating noise will be heard, but the noise should not be higher than 45db, that is, in a quiet environment, only the light hum of the compressor can be heard, and the sound should not be heard at a distance of about one meter from the refrigerator.

When touching the box with your hand, there should be no obvious vibration. 4. Open the refrigerator door with the lighting, the light in the box is on, close the door, and the light is off. 5. After 5 minutes of refrigeration effect, the compressor and condenser heat up, and the suction pipe is cold.

After 30 minutes of operation, open the door of the box, there should be a uniform thin frost on the evaporator, touch the evaporator with your fingers dipped in water, and your fingers should feel sticky. 6. The performance of the thermostat adjusts the thermostat to the stopping position, and the compressor should stop immediately. The ambient temperature is in the range of 15-43, and the compressor should be able to start running when the base material is weak and cold; Adjust to the strong cooling position, and the compressor should run non-stop (referring to the old refrigerator).

7. The cooling speed should be adjusted to the maximum position of the thermostat in the refrigerated room, the temperature in the refrigerated room should be reduced to 10, and the temperature in the freezer room should not be reduced to -5 for more than 2 hours. That is to say, the temperature in the refrigerator should not be higher than 10, and the temperature in the freezer should be -5 or below 2 hours after the refrigerator is started, regardless of whether it is automatically shut down or not.
