Hardware is the key to analyze the difference between variable frequency and fixed frequency air conditioners

Inverter products have been booming in recent years. In addition to inverter air conditioners, inverter washing machines, inverter refrigerators, etc., which have frequently attracted attention, the increasing market share of inverter air conditioners has made it the first choice for many consumers.

At this time, many friends will ask, what is the advantage of variable frequency air conditioner? How is it different from traditional fixed frequency ? Today, I will give you a brief explanation of what variable frequency air conditioner is and what are the product advantages of variable frequency air conditioner.

What is inverter air conditioner?

Inverter air conditioner is based on ordinary air conditioner, with special inverter compressor and inverter control system. Its basic structure and refrigeration principle are exactly the same as ordinary air conditioner. The host of inverter air conditioner can automatically change speed steplessly, and it can automatically provide the required cooling (heating) according to the room conditions; when the indoor temperature reaches the expected value, the air conditioner host will run at a constant speed that can accurately maintain this temperature, realizing "non-stop operation", thus ensuring the stability of ambient temperature.

What are the advantages of variable frequency air conditioners?

1. Energy saving

Since the inverter air conditioner can adjust the operating speed of the compressor at any time through the built-in inverter

2. High temperature control accuracy

It can control the cooling (heating) capacity of the air conditioner by changing the speed of the compressor. The cooling (heating) capacity has a variable range, such as the cooling capacity of the 36GW variable frequency is 360-400W, and the heating capacity is 300-6800W. Therefore, the indoor temperature control can be accurate to ±1℃, making the human body feel very comfortable.

3. Low noise

The inverter air conditioner runs in a balanced manner, with less vibration and noise.

4. Fast temperature adjustment

When there is a large difference between the room temperature and the set temperature, the variable frequency air conditioner will work at maximum power as soon as it is turned on, causing the room temperature to rise or drop rapidly to the set temperature, with obvious cooling (heating) effects.

It can intelligently identify room sizes and distribute cooling (heating) to keep rooms of different sizes at the same temperature.

The inverter air conditioner uses an inverter compressor, which can automatically adjust the operating frequency of the compressor according to the changes in the room's cold (heat) load. After reaching the set temperature, the inverter air conditioner operates at a lower frequency to avoid the discomfort caused by drastic changes in room temperature. When the load is small, the operating frequency is low, and the compressor consumes less power at this time, while avoiding frequent start and stop, thus saving more electricity.

5. Low voltage requirement

Inverter air conditioners have strong adaptability to voltage, and some inverter air conditioners can even be started at 150-240V voltage.

6. Low ambient temperature requirement

The variable frequency air conditioner has strong adaptability to the ambient temperature and can even be started at an ambient temperature of -15t.

Analysis of the disadvantages of variable frequency air conditioners:

1. Due to the limitation of the manufacturing cost of variable frequency air conditioners, the price disadvantage has existed since the launch of variable frequency products. However, in the development history of variable frequency in recent years, the price gap is gradually narrowing, but relatively speaking, there are still not as many price options as fixed frequency air conditioners.

2. Currently, the variety of variable- frequency air conditioners on the market is still not as rich as that of fixed-frequency units.
