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

How to look at variable frequency and fixed frequency of air conditioners

The core difference between variable frequency air conditioners and fixed frequency air conditioners lies in the way the compressor operates:

Comparative itemInverter air conditionerFixed frequency air conditioner
How the compressor worksAutomatically adjust speed according to temperatureFixed speed operation
temperature controlMore stable and less volatileLarger fluctuations
Noise levellowerhigher

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.
