The difference and advantages and disadvantages of inverter refrigerator and fixed frequency refrige

The speed of the two compressors is different from the frequency conversion principle. It is important to know that the compressor speed often determines the temperature of the refrigerator. Frequency conversion can adjust the temperature, but fixed frequency cannot.

In a way, inverter ice. 2.Freshness effect: Inverter refrigerators can keep the internal temperature constant, so they have a better food preservation effect.

The fixed-frequency refrigerator cannot work, its temperature fluctuates, and the freshness effect is very average. 3.The noise level of the inverter refrigerator is low, the noise of the fixed-frequency refrigerator is high, and the effect is obvious when working.

4.Power saving. The starting frequency of fixed-frequency compressors is very high, much higher than that of inverter, and it consumes a lot of power every time it starts.

But inverter refrigerators have smarter systems.

The difference between inverter refrigerator and fixed frequency refrigerator:

1. Power saving. The inverter technology used in the operation of the inverter refrigerator can be used on the refrigerator compressor.

The control of the speed can be better realized, and the fixed-frequency refrigerator relies on the compressor to stop and start to achieve the control of the internal temperature, and the refrigerator compressor consumes electricity when starting, so the inverter refrigerator is more power-saving than the fixed-frequency refrigerator when it is used.

2. Temperature control. When the inverter refrigerator is working, its compressor can adjust the speed according to the needs of the refrigerator to ensure the balance of the internal temperature of the refrigerator, and the temperature control of the fixed-frequency refrigerator is relatively poor when in use, so the balance of the internal temperature of the refrigerator can not be well guaranteed.

3. Noise. The difference between fixed-frequency refrigerator and inverter refrigerator is that the inverter refrigerator controls the speed of the compressor, and the compressor does not need to start frequently, so the noise generated is lower.

4、**。From the ** point of view, inverter air conditioning.

Because of the use of inverter compressors and the most advanced inverter technology, it is better than fixed-frequency air conditioners.

It's 50% higher.

Advantages of inverter refrigerators and fixed-frequency refrigerators.

1. Super fresh-keeping silent energy-saving power-saving inverter refrigerator is based on the original ordinary refrigerator, using a special inverter compressor and drive.

Added inverter control system. Because the inverter compressor can achieve continuously variable speed.

Automatically adjust the speed according to the actual needs of the refrigerator.

2. The quick-freezing capacity of the inverter refrigerator is 20% higher than that of the ordinary refrigerator, and the power consumption is also lower than that of the ordinary refrigerator, and the average daily power consumption is only the degree. In addition, because of the use of inverter technology, the refrigerator does not achieve instantaneous realization when starting or stopping like ordinary compressors, but realizes a smooth transition of speed, thus effectively reducing the start-up and shutdown noise.

Disadvantages of inverter refrigerators and fixed-frequency refrigerators.

1. Because of the high technology of inverter compressor, the inverter refrigerator is also relatively expensive, especially the inverter refrigerator. Therefore, you must choose whether to buy an inverter refrigerator according to your own needs.

2. The inverter compressors are all reciprocating piston compressors, and the working principle and structural characteristics of this compressor determine that the inverter range is relatively narrow, resulting in the advantages of the inverter refrigerator are not as obvious as the inverter air conditioner.

<>1. Energy saving:

The inverter refrigerator does not have wear and tear when it is used instantaneously, and can accurately control the speed of the refrigerator compressor, which has a better energy-saving effect.

Fixed-frequency refrigerator refrigerator compressors consume the most electricity when start-up.

2. Temperature control:

The inverter refrigerator compressor can adjust the speed according to the needs of the refrigerator to ensure the balance of the internal temperature of the refrigerator;

Fixed-frequency refrigerators mainly rely on the stop and start of the compressor to achieve temperature control.

3. Noise: The compressor of the inverter refrigerator can run at high speed according to the temperature, and the noise is low;

4. **: The advantage of fixed-frequency refrigerator is that it is inexpensive, and the disadvantage of fixed-frequency refrigerator is that the freshness is relatively poor. In terms of inverter air conditioning, because of the use of inverter compressors and the most advanced inverter technology, it will be 50% higher than that of fixed-frequency air conditioners.

1. Frequency conversion principle.

The biggest difference between fixed frequency and inverter is that the disturbance lies in the speed of the compressor, and the speed of the compressor determines the temperature inside the refrigerator. The speed of the fixed-frequency refrigerator compressor is fixed, and the speed of the inverter refrigerator compressor is changed according to the temperature, it can be said that the inverter refrigerator is more intelligent, it can make certain adjustments according to the current temperature situation, and the temperature can be better kept constant.

2. Preservation effect.

The internal temperature of the inverter refrigerator can be constant, so the food preservation effect is better, and the internal temperature of the inverter refrigerator fluctuates, and the change in temperature will be reflected on the food, resulting in the general preservation effect.

3. Noise level.

Compared with fixed-frequency refrigerators, inverter refrigerators are less noisy and quieter when working. Because when the fixed-frequency refrigerator is working, the compressor will start frequently according to the temperature change, so the noise is obvious. However, this is not the case with inverter refrigerators, the speed of the compressor can be precisely controlled, and the start-up will not be as frequent, so it will be quieter.

4. Power saving.

The starting frequency of the fixed-frequency refrigerator compressor is much higher than that of the inverter refrigerator, and a lot of electricity will be consumed every time the compressor starts, but the inverter refrigerator will not start frequently because it is more intelligent and the temperature control is more accurate, so the compressor will not start frequently, which will save more electricity.

5. Differences.

With the popularization of technology, the inverter refrigerator is getting cheaper and cheaper, and so far, the inverter refrigerator is basically similar to the fixed-frequency refrigerator, so there will be no big difference in the world.

6. Service life.

The compressor is the core device of a refrigerator, and it is no exaggeration to say that the life of the compressor determines the service life of the refrigerator. The compressor of the fixed-frequency refrigerator is often started, and the wear and tear is relatively high, so compared with the inverter refrigerator, the service life of the fixed-frequency refrigerator is lower.
