Semiconductor car refrigerator

Its principle is to rely on electronic chip cooling, the use of special semiconductor materials constitute the P-N junction, the formation of thermocouple pairs, resulting in the Peltier effect, that is, through the DC refrigeration of a new type of refrigeration method. Refrigeration temperature range of 5 to 65 degrees C. The advantages of this refrigerator is both cooling and heating, environmental protection, pollution-free, small size, low cost, no vibration, noise, long life. The disadvantage is that the refrigeration efficiency is not high, the refrigeration temperature is affected by the ambient temperature, refrigeration can not reach below zero degrees, and the capacity is small.

Compressor refrigerator

Compressor is the traditional refrigerator of the traditional technology, refrigeration temperature is low, -18 degrees 10 degrees. Refrigeration efficiency is high, can make ice, freshness, large volume, is the future development of the mainstream direction of the car refrigerator. But the weight of this refrigerator is heavy, inconvenient to carry, the price is higher. Compressor car refrigerator compressor in the world's major producers for Germany and Japan.
