THE WORKING PRINCIPLE OF COMPRESSOR CAR REFRIGERATOR
Compressor car fridge refrigerator is similar to household refrigerators. They are cooled by compressor power. The refrigeration is fast and powerful. The refrigeration can reach -18°C. It can make ice and preserve freshness. The volume can be large or small. The mainstream direction of the future development of car refrigerators.
Compressor vehicle-mounted refrigerators can be used in cars, or in households through power converters, and are an extension and supplement of household refrigerators. The characteristic is that it is portable and movable, and it is also a car product suitable for self-driving use.
The difference between compressor car refrigerator and semiconductor electronic refrigerator:
Car refrigerators use semiconductor electronics for cooling and heating. The principle is to use direct current to pass through the semiconductor cooling chip to transfer heat from the cold end of the chip to the hot end (Peltier effect) to improve its effectiveness through a cooling fan. In terms of the cooling function, the temperature of the electronic chip can reach 5 degrees, and the temperature of the chip is transmitted to the inner wall of the refrigerator to reach 5 degrees due to wear. This temperature is the low-temperature critical point that electronic refrigeration can reach. This technology originated from Russia's invention of the cold and heat requirements of aircraft in space flight.
Automobile refrigerators usually can cool and heat. The so-called cooling to 5 degrees is an indication of quantification. If the surrounding temperature is relatively high, the temperature difference between the refrigerator's cooling degree and the ambient temperature is generally 15 degrees. The temperature difference of a better quality dual-fan automobile refrigerator can reach 20 degrees. The heating temperature of the refrigerator can usually reach 65 degrees. The hot and cold cups that appear now use the contact type cooling method, that is, the beverage can is directly stuck on the surface of the refrigerator. This type of cooling method is characterized by fast cooling speed, low temperature, and can reach Around zero. The disadvantage is that only a single-tube beverage can be cooled at a time. For people who drive long distances, especially those who travel long distances, the refrigerator with hot and cold functions can bring great convenience to people.
