What is an inverter air conditioner? Maybe there are still many people who don't know what the inverter air conditioner means ? What does the air conditioner's frequency conversion mean? Next, follow the decoration home network Xiaobian to understand what the inverter air conditioner is, why the inverter air conditioner is more power-related content!
What does inverter air conditioner mean? The main unit of the inverter air conditioner is automatically steplessly variable. It can automatically provide the required cooling capacity according to the room condition. When the indoor temperature reaches the desired value, the empty host will operate at a constant speed that can accurately maintain this temperature. It does not stop running, thus ensuring the stability of the ambient temperature.
The inverter air conditioner is a special compressor for frequency conversion based on the ordinary air conditioner, and the frequency conversion control system is added. Its basic structure and cooling principle are exactly the same as ordinary air conditioners. "Frequency conversion" adopts more advanced technology. It has a small voltage at startup and can be started under low voltage and low temperature conditions. This is difficult for some air conditioners to start in some areas due to unstable voltage or low indoor temperature in winter. Certain improvement.
What does inverter air conditioner mean? Inverter air conditioners can be roughly divided into: AC frequency conversion and DC frequency conversion. The AC inverter air conditioner adopts an AC inverter compressor and adjusts the voltage conversion twice. Because there is no starting capacitor relative to the fixed frequency compressor, the circuit loss is reduced, thereby achieving the purpose of power saving.
What is the meaning of inverter air conditioner? Finally, simply say that inverter air conditioner is a frequency converter added to the structure of conventional air conditioner. The compressor is the heart of the air conditioner. Its speed directly affects the efficiency of the air conditioner. The inverter is the control system used to control and adjust the speed of the compressor, so that it is always in the best speed state, thus achieving the purpose of energy saving.
Why is the inverter air conditioner more expensive?
First look at the working principle of variable frequency constant pressure water supply:
1. The faster the pump speed, the greater the energy consumption.
2. When the water demand is small, the low-speed operation can meet the water demand, and the energy is saved compared to the full-speed operation. In other words, running more power at full speed does not produce benefits. (actually, because the water pressure is too large, the quality of the water supply is reduced)
Second, look at the working principle of inverter air conditioner:
1. The faster the compressor speed, the greater the energy consumption.
2. When the cooling capacity is low, the temperature can be maintained by running at low speed, which saves energy compared to full speed operation.
On the three surfaces, the two principles are exactly the same!
Looking closely, there is an essential difference:
Regardless of the amount of water required, the fixed frequency water supply cannot be shut down. However, after the temperature reaches the set value, the fixed frequency air conditioner will enter the stop state. Fixed-frequency water supply, when the water demand is small, the pump can't stop, and the fixed-frequency water supply can't speed, and it can only run at full speed without stopping. At this time, compared with the low-speed operation of the variable frequency water supply, the energy consumed is completely wasted. After the fixed frequency air conditioner reaches the set value, it enters the intermittent operation state: full speed operation, stop, full speed operation, stop... After the inverter air conditioner temperature reaches the set value, it enters the low speed operation state: unless the external temperature causes the temperature to rise suddenly, otherwise Keep running at low speeds.
That is to say, the long-time low-power operation replaces the high-power operation of the fixed-frequency air conditioner for a short period of time. Under the same cooling demand, the two produce the same amount of cooling. If the energy efficiency ratios of the two air conditioners are equal, the power consumption of the two air conditioners is equal, no one is more energy efficient than anyone else.
The question is coming again. Is the energy efficiency ratio of the two the same? This is a cruel reality. The reality is that when using the same compressor, the energy efficiency of the inverter air conditioner is relatively low, that is to say, the inverter air conditioner is more expensive!
Inverter air conditioners cost more electricity for two reasons:
â— First of all, compared with fixed-frequency air conditioners, the inverter air conditioner has one more inverter, and the inverter needs to consume electricity. At the same time, the inverter operation will increase the harmonic loss of the compressor motor, and the two losses are added together. Approximately 2~4% of the rated operating power consumption.
â— Secondly, the general compressor has the highest efficiency at rated speed and the highest energy efficiency ratio. When operating at low speed, the energy efficiency ratio is low.
â— In addition to increasing energy consumption, technology will increase harmonic pollution to the power grid.
The main advantage of inverter air conditioner is that it can be stepless speed regulation, temperature control is more accurate, temperature difference is small, and human body comfort is better. More importantly, the compressor is the heart of the air conditioner, and the inverter improves the control performance of the compressor. With the development of technology, the advantages of inverter air conditioners will be more obvious, and its disadvantages will gradually improve. From this perspective, we should be grateful to such a group of people with rich professional knowledge and high skills and dedication. It is their hard work that promotes and will continue to promote the development of air-conditioning technology, let us enjoy the comfortable working and living environment brought by air conditioning.
In the face of the customer's question "Does the inverter air conditioner really save power?", we are obliged to tell them the truth and tell them that compared with fixed-frequency air conditioners, inverter air conditioners have better performance, telling them that in terms of current technology, frequency conversion Air conditioners can't save power, at least not significantly save power. Looking forward to one day, the integrity and daring to face the reality of the business to play "not necessarily the most energy-efficient, but may be the best performance of the inverter air conditioner" similar advertising, China's inverter air-conditioning technology development will enter a new milestone!
The above is about the meaning of the inverter air conditioner, why the inverter air conditioner is more cost-effective detailed answer, I do not know if you are satisfied with the introduction of the decoration home network Xiaobian. If you want to know more about the exciting content, please continue to pay attention to our decoration encyclopedia!
