Since 2023, the market share of fixed frequency air conditioners has increased from 15% to 28%, reflecting a shift in consumers' concept of "durability first". Under extreme high temperature conditions, fixed frequency air conditioning exhibits significant advantages: its energy efficiency is 8-12% higher than that of variable frequency products under operating conditions above 35 ℃, cooling to 5 ℃ only takes 4 minutes and 30 seconds, and its nighttime silent performance is more stable. The difference in maintenance costs is more critical. The average maintenance cost of variable frequency air conditioners is 860 yuan/time, which is 2.7 times that of fixed frequency models (320 yuan/time). The electronic expansion valve is stuck and the variable frequency module overheats, becoming high-frequency faults.
From the perspective of full lifecycle cost, the total cost of a fixed frequency machine is more than 700 yuan less than that of a variable frequency machine after ten years of use. However, the selection should be based on the scenario: fixed frequency is suitable for short-term use spaces such as living rooms, and variable frequency is still recommended for long-term use areas such as bedrooms. It is worth noting that after the implementation of the new national standard, old fixed frequency machines have gradually withdrawn from the market. Currently, the strengthened version models on sale mostly use commercial grade compressors, and some brands also provide a "10-year warranty maintenance fund" to balance durability and protection.
