The refrigeration performance of car refrigerators is affected by a series of factors such as ambient temperature and voltage stability. The refrigeration performance of refrigerators of different brands varies greatly.
Many refrigerators are claimed to be able to cool down to minus 20 degrees, and the actual effect is often unable to reach the preset temperature. This does not rule out that some inferior refrigerators have the problem of poor sealing when they leave the factory, and the actual cooling time is longer. On the other hand, a normal car refrigerator can be turned into ice cubes when it is opened for about 3-5 hours at an ambient temperature of 20 degrees, and a bottle of mineral water is put into it.
The most important factor affecting the refrigeration effect and price of a refrigerator is the compressor. At present, there are more than a dozen types of compressors used in domestic car refrigerators, and the prices and performance are also uneven.
But it is undeniable that the price of domestic compressor brands is 20%-50% cheaper. If the performance requirements of the product are not so high, you can choose to replace the refrigerator in two years.
Good car refrigerators can often move frequently, have good shock resistance, can work normally under complex and bumpy road conditions, and can pass the most stringent vibration test of the car factory.
Generally speaking, whether you are driving in a mountainous area or in a city, you will encounter the situation of climbing. A good refrigerator should still work normally when the inclination is ≤30°.
At present, the outer shells of different car refrigerators on the market are also quite different, which is also one of the secondary factors that affect the price of refrigerators.
In order to reduce the cost of cheap car refrigerators, in addition to saving the compressor, the outer casing should also be saved. Therefore, the outer casing of some cheap machines has a strong plastic feel, and it is easy to leave scratch marks when touched at random, and some even handle and seal the door. If the installation is not firm, the outer wall of the fuselage will be damaged if it is slightly exposed to external force.
