What are the advantages and disadvantages of variable frequency air conditioning

Four seas network: variable frequency air conditioning is a relatively new type of air conditioning product. It is more comfortable and energy-saving than constant frequency air conditioning. What are the advantages and disadvantages of variable frequency air conditioning? Let's have a look.

What are the advantages and disadvantages of variable frequency air conditioning

​​​​​​​

Advantages of variable frequency air conditioning

1, save electricity.

Because the frequency conversion air conditioner can adjust the operation speed of the air conditioner compressor at any time through the built-in frequency converter, so as to use the energy reasonably. Because its compressor will not be opened frequently, it will keep the compressor in a stable working state, which can make the air conditioner achieve the effect of energy saving more than 30%..

2. Low noise

Due to the balanced operation of the variable frequency air conditioner, the vibration of the compressor is relatively small when it is running, and the noise is also reduced, which is very friendly for people who need quiet sleep.

3. High temperature control accuracy

It can control the cooling (heating) quantity of the air conditioner by changing the speed of the compressor. Its cooling (heat) capacity has a change range, for example, the cooling capacity of 36gw frequency conversion changes to 360-400w, and the heating capacity changes to 300-6800w, which can accurately control the indoor temperature to & plusmn; 1 ℃, making the human body feel very comfortable

4. Fast temperature regulation

When there is a large difference between the room temperature and the fixed temperature, the variable frequency air conditioner will work with the maximum power as soon as it is turned on, so that the room temperature will rise or fall to the set temperature rapidly, and the refrigeration (heat) effect is very obvious.

5. Low voltage requirements

Variable frequency air conditioning has strong adaptability to voltage. It can also be used when the voltage is low. Some variable frequency air conditioning can be started at 150-240v.

6. Low ambient temperature requirements

Variable frequency air conditioning has low requirements for ambient temperature. Some air conditioners can even be started at - 15 ℃. Unlike constant frequency air conditioning, it is basically impossible to make heat at - 5 ℃.

7. Keep room temperature constant

Variable frequency air conditioner adopts variable frequency compressor, which can automatically adjust the operating frequency of the compressor according to the change of cold (hot) load in the room. After reaching the set temperature, the variable frequency air conditioner operates at a lower frequency, avoiding the discomfort caused by the drastic change of room temperature. When the operating frequency is low when the load is hourly, the power consumed by the compressor is small, and frequent start and stop are avoided at the same time, so as to save more power.

Disadvantages of variable frequency air conditioning

1. High failure rate

Because the frequency conversion air conditioning technology is not as skilled as the fixed frequency air conditioning technology, and the equipment requirements are relatively high, so the air conditioning is more prone to failure. The maintenance frequency is high, and the maintenance cost is high.

2. High price

Compared with constant frequency air conditioning, the price of variable frequency air conditioning is more expensive, which is 30% to 40% higher than that of air conditioning of the same brand and the same refrigerating capacity, and the cost of air conditioning is relatively high.

3. Continuous power on

The use of variable frequency air conditioning requires the air conditioning to be on for a long time. For our country, most families don't turn on the air conditioner all the time. Generally, they only turn on the air conditioner for a few hours after they come back from work. The advantages of the variable-frequency air conditioner can't be reflected, because the variable-frequency air conditioner needs to operate continuously to save power.

4. Core technology

The technology of variable frequency air conditioning is not perfect. Although it has many advantages, we all know that the more advanced the machine is, the more complex the parts are, and the probability of problems will be correspondingly increased. The frequency conversion technology of our domestic manufacturers has not reached a relatively high level, and the technology of the core components of frequency conversion is in the hands of the Japanese.
