How to look at variable frequency and fixed frequency of air conditioners
With the advent of high temperatures in summer, air conditioners have become an essential appliance in homes and offices. Recently, the choice between variable frequency and fixed frequency air conditioners has become a hot topic, and consumers often face confusion when purchasing. This article will compare variable frequency and fixed frequency air conditioners in terms of energy efficiency, price, usage scenarios, etc. to help you make a more informed choice.
1. The basic difference between variable frequency and fixed frequency air conditioners

The core difference between variable frequency air conditioners and fixed frequency air conditioners lies in the way the compressor operates:
| Comparative item | Inverter air conditioner | Fixed frequency air conditioner |
|---|---|---|
| How the compressor works | Automatically adjust speed according to temperature | Fixed speed operation |
| temperature control | More stable and less volatile | Larger fluctuations |
| Noise level | lower | higher |
2. Energy efficiency comparison
Inverter air conditioners are more energy efficient when running for a long time and are suitable for homes or offices that need to turn on the air conditioner for a long time. Fixed-frequency air conditioners are more suitable for short-term use.
| Energy efficiency index | Inverter air conditioner | Fixed frequency air conditioner |
|---|---|---|
| Energy efficiency for long term use | high | in |
| Energy efficiency for short periods of time | in | high |
| Energy saving effect | Significantly | Average |
3. Price and maintenance costs
The initial purchase price of an inverter air conditioner is higher, but long-term use can save electricity bills. Fixed-frequency air conditioners are less expensive, but your electricity bills may be higher.
| Cost item | Inverter air conditioner | Fixed frequency air conditioner |
|---|---|---|
| purchase price | higher | lower |
| Maintenance cost | medium | lower |
| long term electricity bill | lower | higher |
4. Recommended applicable scenarios
Depending on the usage scenario, variable frequency and fixed frequency air conditioners have their own advantages:
| scene | Recommended type | Reason |
|---|---|---|
| family bedroom | Frequency conversion | Stable temperature and low noise |
| living room | Fixed frequency | Short time use, low cost |
| office | Frequency conversion | Long time operation, energy saving |
5. Consumers’ recent hot spots
In the past 10 days, consumers’ attention to air conditioners has mainly focused on the following aspects:
1.Energy saving and environmental protection: As electricity bills rise, more people are paying attention to the energy-saving performance of air conditioners.
2.Intelligent control: Inverter air conditioners that support APP control have become a new favorite.
3.health function: Air conditioners with sterilization and self-cleaning functions are more popular.
6. Purchase suggestions
1. If you have sufficient budget and need to use it for a long time, give priority to an inverter air conditioner.
2. If the frequency of use is not high or the budget is limited, fixed-frequency air conditioners are a more economical choice.
3. Pay attention to energy efficiency labels and choose energy-efficient products to save long-term electricity bills.
Through the above comparison, I believe you will have a clearer understanding of variable frequency and fixed frequency air conditioners. Choose the appropriate air conditioner type according to your needs and enjoy a comfortable and cool summer.
