The working principle of car refrigerator

Today, Ningbo Jiahao Appliance Co.,ltd. will introduce you the working principle of car refrigerator. Our Beer Kegerator products have been recognized by customers all over the world for their excellent quality!
A car refrigerator refers to a refrigerator that can be carried in a car. Car refrigerators are a new generation of refrigeration and refrigeration appliances popular in the international market in recent years.
There are two main types of car refrigerators on the market. One is a semiconductor car refrigerator, which is based on electronic chip cooling; the other is a compressor car refrigerator. The compressor is a traditional technology of a traditional refrigerator, and the cooling temperature is -18 Degree 10 degrees. The refrigeration efficiency is high, it can make ice and keep fresh, and the volume is large.
Car refrigerators are the continuation of household refrigerators, and can use semiconductor electronic refrigeration technology, or they can be cooled by compressors. Generally speaking, there is little noise and pollution. When driving, just insert the power plug into the cigarette lighter hole to cool down the refrigerator.
There are two main types of car refrigerators on the market. One is a semiconductor car refrigerator. Its principle is to rely on electronic chips for cooling, and use a PN junction composed of special semiconductor materials to form a thermocouple pair, which produces the Peltier effect, that is, it is cooled by direct current. A new type of refrigeration method. The refrigeration temperature range is 5 to 65 degrees. The refrigerator has the advantages of cooling and heating, environmental protection, no pollution, small size, low cost, no vibration, noise, and long life. The disadvantage is that the refrigeration efficiency is not high, the refrigeration temperature is affected by the ambient temperature, the refrigeration cannot reach below zero, and the capacity is small. The other is a compressor car refrigerator. The compressor is the traditional technology of traditional refrigerators. The refrigeration temperature is low at -18 degrees and 10 degrees. High refrigeration efficiency, ability to make ice, keep fresh, and large size are the mainstream direction of the future development of car refrigerators. However, this kind of refrigerator is heavier, inconvenient to carry, and expensive. Compressors for automobile refrigerators are mainly produced in Germany and Japan in the world.
