Inverter Air Conditioner: a new point of growth for permanent magnet materials

Air conditioners that meet the first-class energy efficiency standard can obtain a market access pass. It is expected that inverter air conditioners will experience explosive growth and market penetration will further increase. From July 1, 2020, my country officially began to implement the GB21445-2019 “Energy Efficiency Limits and Energy Efficiency Levels of Room Air Conditioners” standard (hereinafter referred to as the “New Standard”). This standard unified the energy efficiency evaluation standard system for frequency conversion and fixed frequency air conditioners for the first time. Under the new energy efficiency evaluation standard system, fixed-frequency air conditioners with the original third-level energy efficiency standards and single-cooling fixed-frequency air conditioners and inverter air conditioners with the original second-level energy efficiency standards will not meet the market access threshold and cannot obtain a market access pass.

Rare earth permanent magnet inverter air conditioner

Inverter air conditioner compressors mainly include ferrite inverter compressors and rare earth permanent magnet inverter compressors. Under the “New Standard”, it is difficult for ferrite inverter compressors to meet the requirements of the first-class energy efficiency standard. In the case of choosing one of the two, the use of rare earth permanent magnet inverter compressors has become the only solution. In addition, local policies will give certain financial subsidies to manufacturers of inverter air conditioners that meet the first-level energy efficiency standards; and compared with ferrite inverter air conditioners, the purchased rare earth permanent magnet inverter air conditioners are smaller in size and have better energy-saving effects. It is more popular with consumers; ferrite inverter compressors not only fail to meet energy efficiency standards, but also consume more materials such as silicon steel and copper in production than rare earth permanent magnet inverter compressors. Considering many aspects, air conditioners using rare earth permanent magnet inverter compressors will become the mainstream consumption trend. It is foreseeable that inverter compressors made of rare earth permanent magnet materials will become a new market trend, and their market penetration rate will further increase, thereby stimulating rare earth The demand for permanent magnet materials is increasing.

Application of Rare Earth Permanent Magnet Materials in Inverter Air Conditioning Compressor

After the introduction of the “New Standard”, in 2021, the total sales volume of air conditioners will be 154 million units, a year-on-year increase of 9.1%. In 2021, the market penetration rate of inverter air conditioners will be 94.6%, a sharp increase of 41.7pct compared with 2020. It is foreseeable that the penetration rate of inverter air conditioners will continue to expand in the future, approaching 100%. Inverter Air Conditioner permanent magnet materials
