Q: Does the car refrigerator need to go through the electricity?: There are two kinds of car refrigerator on the market, one is the semiconductor car refrigerator, its principle is to rely on electronic chip cooling, the use of special semiconductor materials constitute the PN junction, the formation of thermocouple pairs, resulting in Peltier effect, that is, by DC cooling A new type of refrigeration method. The cooling temperature range is 5 to 65 degrees. The advantages of this refrigerator is both cooling and heating, environmental protection, pollution-free, small size, low cost, work without vibration, noise, long life. The disadvantage is that the cooling efficiency is not high, the cooling temperature is affected by the ambient temperature, the cooling can not reach below zero, and the capacity is small. The other is the compressor refrigerator, the compressor is the traditional traditional refrigerator technology, cooling temperature is low, -18 degrees 10 degrees. Cooling efficiency, can ice, fresh, large size, is the future direction of the development of car refrigerator. But this weight is heavy, easy to carry, the price is higher. Compressor Car refrigerator compressor The world's leading producer for Germany and Japan.

Q: My small refrigerator is Haier, you can run under 220v 5 hours, but can not be used for a long time, how can the refrigerator at home to play a role? Need DC 12v, power in the 38-48w. What kind of transformer does a DC power cord need to use? Or how to do? consult!: Do not understand the small refrigerator circuit, can only say something about. The car is only 12V DC battery, so with 12V power supply, do not know the compressor is a direct DC work, or with the inverter will be 12V DC into 220V AC power use. If it is to use the inverter, then just to find the compressor power wiring, directly with the AC on the line. If 12V DC work, it would use a 100W or so transformer, primary 220V, secondary 14V, the production of a 12V, 5A or more current rectifier circuit.

Q: What brand of car refrigerator is best to buy?: The cost of electricity is very small, only tens of watts, but also convenient, hot days do not want to get off to buy water should have a

Q: The principle of car refrigerator: Do you know that some semiconductor materials with a certain voltage, in its pn junction at both ends will have a huge temperature difference? People are using this temperature difference effect, invented a portable or car refrigerator. But the efficiency of the semiconductor refrigerator is not high enough, so the high-end point of the car still use a small refrigerator or air conditioning, refrigerator dual-use compressor refrigerator.

Q: Intend to buy a small refrigerator, it was said to increase fuel consumption, it was said that when driving the power is actually wasted, not clear: Car refrigerator is divided into two kinds. With power and no power, with the power of the comparison of fuel consumption, no power supply weight more power consumption.

Q: Is it easy to use the car refrigerator? How much is the car refrigerator?: There are two kinds of car refrigerator on the market, one is hot and cold box, affected by the ambient temperature, can be heating and cooling. But the cooling effect is not ideal. So it is not recommended. Another car refrigerator is a car compressor refrigerator, a good brand generally refrigerated up to - 18 °, and the temperature is adjustable, very good.

Q: Does the fridge charge the oil?: In fact, the power of the car refrigerator only tens of watts, equivalent to a lamp power consumption. When the car engine starts, the car generator power to the battery charge, when the battery is full, no generator is also a waste of electricity, car refrigerator is to use surplus, do not increase fuel consumption!

Q: What kind of car refrigerator is better?: It depends on what you want the kind of cooling effect of the semiconductor refrigeration car refrigerator (which can be used to cool the car) is 18-25 degrees lower than the ambient temperature, a 25-30 degrees lower than the ambient temperature (dual system Car refrigerator) There is a kind of ice can be achieved can be achieved under the temperature of 18 degrees can be automatically adjusted if you want to cool the good effect that is good compressor refrigerator
