Uses: Car refrigerator, cooling/warming mini refrigerator, 4L car home dormitory dual-use refrigerator
Advantages and disadvantages: no need for refrigerant (which is required by compression and absorption type refrigerator), environmental pollution, small in size, low cost, no vibration, no noise, long life.
The car refrigerator relies on electronic chip to refrigerate and uses special semiconductor materials P-N junction to form thermocouple pairs, resulting in the Peltier effect, that is to say, using a new cooling method via a DC voltage. Refrigeration temperature ranges from 5 to 65 degrees celsius.
Scope of application: preservation and heat insulation for drinks, food, fruit, milk, red wine and some drugs that need low temperature storage.
Disadvantage: the cooling temperature depends on the surrounding temperature, can not reach below zero, just suitable for preservation and heat insulation.
