Mechanical temperature control
Mechanical temperature control refers to a temperature control method that uses a mechanical method to regulate the refrigeration of a refrigerator. The system is relatively simple and can ensure that food does not deteriorate, but the temperature is unstable and cannot fully meet the needs of freshness preservation.
Computer temperature control
Computer temperature control generally uses a programmable core as the core, and is equipped with a thermal element as a temperature sensor. The independent refrigeration system makes the temperature control accuracy much higher than the mechanical temperature control. The cooling effect is better and the problem of food skewer is eliminated.
Direct cooling refrigeration
The low temperature natural convection on the surface of the evaporator reduces the temperature in the box, but the temperature is not uniform. It is relatively power-saving, and the effective volume is large under the same volume.
Air-cooled refrigerators are also called frost-free refrigerators. The freezer automatically defrosts and has low humidity, and the food is easy to air dry and dehydrate, which is suitable for use in humid areas. The power consumption is higher than the direct cooling type, and the effective volume is small under the same volume.
Hybrid (wind direct cooling)
It is a computer-controlled temperature-controlled double-cycle system, which combines air-cooling and direct-cooling. The refrigerator is frost-free and has good fresh-keeping effect. It can send cold directly to the refrigerating room and air to the freezer. It is equipped with two intelligent dual dynamic cooling systems, which are quick-cooling, quick-freezing, and rapid cooling.
It is commonly known as a variable frequency refrigerator. Because the cooling capacity can be adjusted, the cooling capacity of the refrigerator can be well matched with the load of the refrigerator. When the cooling capacity required by the refrigerator is small, the compressor can run at low speed.
Frozen stars of a refrigerator represent the freezing capacity of the refrigerator, and each star represents a 6 degree cooling capacity. The higher the star, the stronger the cooling effect. Generally, the highest star is 5 stars, and the common star is 3-4 stars.
The cooling capacity refers to how many kilograms of food the refrigerator can freeze from 25 degrees Celsius to -18 degrees Celsius in 24 hours. Refrigeration capacity is generally more than 12kg / 24h.
Daily power consumption
The nominal daily power consumption of a refrigerator is measured under specific conditions and is also related to the temperature adjustment of the refrigerator. The lower the temperature adjustment, the more electricity it consumes.
