1. Energy saving: inverter refrigerator >; Fixed frequency refrigerator.
(1) Frequency conversion technology is adopted in the operation of frequency conversion refrigerator, which can be started instantly without abrasion, and then the speed of refrigerator compressor can be accurately controlled, with good energy-saving effect;
(2) The constant frequency refrigerator controls the internal temperature by stopping and starting the compressor, and the refrigerator compressor consumes the most power when it is started;
2. Temperature control: Frequency conversion refrigerator is more accurate than fixed frequency refrigerator.
(1) When the inverter refrigerator is working, the speed of the compressor can be adjusted according to the needs of the refrigerator to ensure the internal temperature balance of the refrigerator;
(2) The constant frequency refrigerator mainly controls the temperature by stopping and starting the compressor. The rotating speed of the compressor of the fixed frequency refrigerator is fixed during its operation, usually between 2950 and 3000 revolutions. During the operation of the refrigerator, when the internal temperature of the refrigerator reaches the set temperature, the compressor will stop running, and when the temperature rises, the compressor of the refrigerator will start again. This will cause the temperature to fluctuate greatly and the temperature control ability is not accurate enough;
3. Noise: inverter refrigerator
(1) The compressor of inverter refrigerator can run at high speed according to the temperature, and it is not necessary to start the compressor frequently according to the temperature change, so the noise is low;
(2) During the operation of the fixed-frequency refrigerator, due to the change of temperature, it is necessary to start the compressor frequency frequently, resulting in loud noise.
Frequency conversion refrigerator: Frequency conversion refrigerator is a kind of refrigerator produced by using single-phase AC motor as driving motor and single-phase AC motor as frequency conversion power supply to adjust the refrigeration capacity of compressor. When the heat load is large, the refrigeration capacity of the compressor is large, and when the heat load is small, the refrigeration capacity of the compressor is small, thus increasing the evaporation temperature and reducing the power consumption.
