Leiditech recommends protective devices and solutions for refrigerators
The refrigerator control system mainly consists of a main control board, display control board, electromagnetic valve, temperature sensor, etc. The main control board and display control board are mainly used to control the start/stop of the refrigerator and other functional settings of the refrigerator. In addition, their degree of networking is becoming increasingly high, facilitating the use of cloud connections and mobile applications to monitor information such as food humidity and temperature inside the refrigerator.
In 2018, the retail volume of the refrigerator market reached 31.48 million units, a year-on-year decrease of 6.2%; The retail sales amounted to 93 billion yuan, a slight increase of 0.7% year-on-year. In recent years, the refrigerator industry has entered a steady state of development. Although the market increment fluctuates every year, the overall change is not significant.
