The compressor permanent magnet of inverter air conditioner
The compressor of the inverter air conditioner is a permanent magnet material The compressor of the inverter air conditioner is an important downstream of the permanent magnet material. At present, the magnets used in the air conditioner compressor are divided into two types: ferrite permanent magnet material and high-performance NdFeB permanent magnet material: iron Oxygen permanent magnet materials have low performance and will demagnetize in the environment of minus 7 degrees or minus 8 degrees. They are mostly used in the production of low-end inverter air conditioners; high-performance NdFeB permanent magnet materials are mainly used in the production of high-end inverter air conditioners. With the support of energy-saving and environmental protection industrial policies and the trend of technology upgrading, the application of ferrite permanent magnet materials in inverter air conditioners will gradually be replaced by high-performance NdFeB permanent magnet materials.
The compressor permanent magnet of inverter air conditioner
NdFeB magnets for inverter compressors should have excellent magnetic properties, low temperature coefficient, low irreversible demagnetization rate at high temperature, and strong corrosion resistance in high temperature, Freon and refrigerating machine oil environments. Generally, high-performance NdFeB permanent magnets with properties of 42SH, 38UH, 38EH, etc. are selected.
Since 2017, the proportion of the output of inverter air conditioners in my country to the total output of household air conditioners has remained stable at about 30%. In the fourth quarter of 2019, the output of inverter air conditioners was 15.99 million units. Calculated based on the use of 0.12kg of high-performance NdFeB for each inverter air conditioner, the industry’s consumption of high-performance NdFeB in the fourth quarter was about 1,919 tons, which was basically the same as the previous quarter; the annual consumption of high-performance NdFeB in 2019 was 8,000 tons or so.
