Two big "advantage"
Energy-saving advantages: the use of frequency converter technology is mainly run from the refrigerator, use energy-saving, by changing the compressor speed to change the cooling capacity of the refrigerator, so that the cooling capacity can be based on the ambient temperature and load change, thereby reducing downtime open and reduce power consumption. Meanwhile, a refrigerator used in the DC speed compressor and reduces the excitation losses compressor motor, compressor efficiency is further improved.
Noise reduction advantages: compressor uses a brushless DC motors, three-phase stator windings, rotor pole permanent magnet excitation using without excitation coils, energy saving, no heat, by increasing the magnetic pole arc coefficient (ie increasing magnetic pole arc ), poly axial magnetic rotor overall magnetization and other measures to significantly improve the air-gap flux density of the motor to increase output, its starting torque up to 3.5 times the rated torque, so starting torque brushless DC motor much larger than the traditional single-phase asynchronous motors, compressors ensures quick start, smooth operation.
