Is Midea s full DC air conditioner really that good? What are its advantages over ordinary DC air co

Compared with Midea's ordinary DC air conditioner. The fan motor of the indoor unit and the fan motor of the outdoor unit have been changed from AC motor to DC motor, with low noise, low power consumption and long life. It's not as powerful as advertised.

In terms of data, the full DC inverter air conditioner with large frequency conversion can save more than 20 kilowatt-hours of electricity than the ordinary DC inverter air conditioner in 1136 hours. The noise can be lower. Moreover, ordinary DC inverter air conditioners promise 1 year of free replacement and 10 years of free repair.

Full DC is 2 years free replacement and 10 years free repair. Midea air conditioners are still worth buying. Midea and Gree are good machines worth buying, and others are not recommended to buy.

Midea because the quality is about the same as Gree, ** cheap, so it is more cost-effective.

Compared with ordinary DC inverter air conditioners, Midea's full DC inverter air conditioners have significant technical advantages: first, the energy-saving effect is significantly improved; Secondly, the operating noise is significantly reduced, and the moisturizing effect is remarkable; In addition, the air conditioning operation is more reliable and the operation regulation is more precise.

Midea's full DC inverter air conditioner refers to the three core motors of the air conditioner (inverter compressor motor, indoor fan motor, outdoor fan motor) all use powerful DC motors, and integrate the flexible adjustment advantages of the three DC motors through the full DC control module, and then optimize the matching air conditioning system, so as to give full play to the excellent performance of the full DC inverter air conditioner. The rotor of the AC motor of the DC inverter air conditioner is a coil, which needs to be energized to generate a magnetic field, and the power loss has always existed, while the DC motor of the full DC inverter air conditioner has basically no rotor loss due to the use of permanent magnet materials in the rotor, and the energy-saving effect is very obvious; As long as the ambient temperature is in line with the ambient temperature, Midea's full DC inverter first-class energy-efficient machine can achieve the power-saving effect of 8 hours of electricity.

If you still have questions, you are welcome to ask questions to the company in the United States; I wish you a smooth work and a happy life!

At least compared with ordinary DC inverter air conditioners, the power saving effect of full DC air conditioners can reach up to 59%.

Of course, it is an upgraded version of an ordinary DC air conditioner.

Dear, don't you know that "the future of air conditioning is in inverter, and the future of inverter is in full DC"?

This question is too technical, so it's better to ask a professional.

First, the meaning is different:

DC inverter air conditioner.

The compressor uses a DC motor.

The electronic control system is complex and belongs to synchronous control.

The compressor of AC inverter air conditioner uses AC motor, and the electronic control system is relatively simple and belongs to asynchronous control.

Second, the use is different:

DC inverter air conditioner is 20%-30% more energy-saving than AC inverter air conditioner, and DC inverter is better than AC inverter in terms of comfort, quietness, life, control accuracy, etc.

The performance of these two machines is definitely superior to full DC, because the performance of AC motors is relatively low. Midea's DC motor uses a permanent magnet rotor, which generates a magnetic field independently without current during operation, which is more energy-saving and efficient.

Advantages:

The AC motor of the DC inverter air conditioner is driven by the magnetic field generated by the current, and the silent effect of the air conditioner is poor, while the rotor of the DC motor of the full DC inverter air conditioner is driven by the permanent magnetic field, which can realize the ultra-quiet operation of the air conditioner as low as 20 decibels; The air conditioner runs more reliably.

When the AC motor of DC inverter air conditioner regulates the speed, it is a relatively unstable process, and the reliability and stability of the operation are poor, and the DC motor of the full DC inverter air conditioner adopts brushless operation technology, which can adjust the speed by changing the voltage or current, and the operation is more reliable; More precise operation adjustment.

First, the subject is different.

1. DC inverter air conditioner: an air conditioner that adopts a DC inverter control system and a corresponding DC inverter compressor; The most energy-saving effect; The temperature control technology is more precise.

2. Full DC inverter air conditioner: refers to the three core motors of the air conditioner (inverter compressor motor, indoor fan motor, outdoor fan motor) all use powerful DC motors.

Second, the characteristics are different.

1. DC inverter air conditioner: it converts the 50hz power frequency AC power supply into DC power supply and sends it to the main circuit of the power module, and the power module is also controlled by the microcomputer, the difference is that the output of the module is a DC power supply with variable voltage, and the compressor uses a DC motor.

2. Full DC inverter air conditioner: The DC motor of the full DC inverter air conditioner uses permanent magnet materials for the rotor, which basically does not use the rotor loss, and the energy-saving effect is very obvious; Significantly less noisy operation.

Third, the functions are different.

1. DC inverter air conditioner: The efficiency of DC inverter compressor is 10%-30% higher than that of AC inverter compressor, the noise is 5-10 decibels, and the relative cost is slightly higher.

2. Full DC inverter air conditioner: Through the full DC control module, the flexible adjustment advantages of the three DC motors are integrated, and then the air conditioning system is optimized to give full play to the excellent performance of the full DC inverter air conditioner.

Full DC means that the whole machine running parts are driven by DC motors. It uses the characteristics of DC smooth stepless speed regulation to play an energy-saving role. It is also commonly referred to as a full DC speed air conditioner in the industry. Low failure rate, high cost and low operating cost.

DC inverter means that the compressor is DC driven. The control mode is the power frequency AC conversion DC control and driving mode of the inverter. It is referred to as frequency conversion speed regulation.

Because there are many control components, the equipment failure rate is high, and there is no full DC energy saving. The cost is low, and the operating cost is higher than that of full DC.

With the innate advantages of DC motors and the advanced control system, the full DC inverter air conditioner has reached an almost perfect state in terms of energy saving level and the performance of the whole machine.

DC inverter air conditioner: the use of speed adjustable DC inverter compressor, in which the fan motor is AC, because the compressor from AC to DC inverter, the energy-saving effect and the performance of the whole machine have been significantly improved, but the fan motor still uses AC motor, the energy-saving level of the whole machine still has a large room for improvement.

1.DC frequency conversion refers to the use of DC frequency conversion for some components and compressors; And the outdoor unit fan does not have inverter.

2.Full DC frequency conversion refers to the use of DC frequency conversion technology for the entire air conditioner; Even the outdoor unit fan changes speed according to the change in the operation of the air conditioner.

3.Inverter air conditioners generally have to reach more than two levels in the inverter energy efficiency value before they are called full DC inverter [that is, the energy efficiency reaches above.

4.The efficiency of all full DC is generally higher than that of DC inverter.

With the innate advantages of DC motors and the advanced control system, the full DC inverter air conditioner has reached an almost perfect state in terms of energy saving level and the performance of the whole machine.

DC inverter air conditioner: the use of speed adjustable DC inverter compressor, in which the fan motor is AC, because the compressor from AC to DC inverter, the energy-saving effect and the performance of the whole machine have been significantly improved, but the fan motor still uses AC motor, the energy-saving level of the whole machine still has a large room for improvement.
