Circuit design of Rongsheng 5CD-103 refrigerator

A refrigerator is a cabinet or box that keeps food or other items cold and contains a compressor and an ice machine for freezing; a storage box with a refrigeration device. The capacity of household refrigerators is usually 20 to 500 liters. In 1910, the world's first compression refrigeration household refrigerator was launched in the United States. In 1925, the Swedish Lido Company developed a household absorption refrigerator. In 1927, General Electric Company of the United States developed a fully enclosed refrigerator. In 1930, air-cooled continuous diffusion absorption refrigerators using different heating methods were put on the market. In 1931, the new refrigerant Freon 12 was successfully developed. In the second half of the 1950s, it began to produce household thermoelectric refrigerators. China began producing refrigerators in the 1950s. The figure shows the circuit design of Rongsheng 5CD-103 refrigerator.
