The rotational speed of the compressor of the inverter-free refrigerator is fixed during its operation, usually between 2950 and 3000 revolutions. During operation, 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.
The constant frequency refrigerator mainly controls the temperature by stopping and starting the compressor. Compared with the frequency conversion refrigerator, the temperature control accuracy of the fixed frequency refrigerator is relatively poor, and the noise generated during operation is relatively large, which consumes more power.
Frequency conversion refrigerator is a popular refrigerator in recent two years, which directly uses frequency conversion compressor. In addition, the frequency conversion controller is added to the control system of the refrigerator, which can directly control the refrigeration capacity of the refrigerator and reduce the restart times.
In addition, the temperature inside the refrigerator can be accurately controlled by continuously adjusting the rotating speed of the compressor. When food stays in such an environment, the loss of water and nutrients can be reduced and the freshness is better. Because the inverter refrigerator can be adjusted, the refrigeration capacity and load of the refrigerator can be more matched, which reduces unnecessary consumption, thus reducing the power consumption and making the refrigerator more energy-saving.
Extended information: introduction of inverter refrigerator;
1. 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.
2. 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. The characteristic of frequency conversion refrigerator is that the speed of refrigerator compressor is not fixed, and the speed is fast when the temperature is high.
3. To achieve the goal of cooling down as soon as possible, when the temperature is low, run at the lowest speed and keep the temperature. No instant start-up wear, long service life. Frequency conversion refrigerator saves electricity and is quiet. Simply speaking, frequency conversion technology is to convert alternating current of one frequency into alternating current of another frequency; Frequency converter is an electrical device that changes the frequency of power supply.
4.0. 1 degree frequency conversion technology is independently developed by Meiling, which can accurately control the temperature of 0. 1℃, stabilize the temperature in the refrigerator, reduce the influence of temperature fluctuation on food preservation, and effectively prolong the food preservation time.
5. According to the actual needs of refrigerator operation, realize the accurate frequency conversion of 1Hz, always ensure the refrigerator in the best operation state, effectively balance the temperature in the refrigerator, and reduce the energy consumption of refrigerator operation loss. After frequency conversion optimization and upgrading, the energy consumption of products can be reduced by more than 10%. ?
