Car refrigerators are generally divided into electronic semiconductor refrigerators and compressed locomotive refrigerators according to different working principles. Which is better?Below, Xiaobian compares the semiconductor and compressed locomotive refrigerators for everyone, and introduces car refrigerators to buy skills and popular car refrigerators brand to provide some help for you to choose a car refrigerator.
Which one is better for semiconductor and compressed locomotive refrigerator
Semiconductor car refrigerator
Working principle: The principle of semiconductor electronic refrigeration and heat production is used. The principle is to use DC current through semiconductor refrigeration chips to transmit heat from the chips cold end to the thermal end (Palt Piccin) to improve its effect through the heat dissipation fan.-5 to 65 degrees.
Product characteristics: It can cool down and heat, environmental protection, pollution -free, small volume, low cost, no vibration, noise, and long life during work.
Disadvantages: The cooling efficiency is not high. Due to the ambient temperature, the refrigeration temperature cannot reach less than zero, and the capacity is small.
Compressor vehicle carrier refrigerator
Working principle: Similar to home refrigerators, all through compressor power refrigeration, cooling and strong refrigeration, refrigeration can reach -18 ° C. The compressor adopts full closed, fluoride, and maintenance technology.damage.
Product characteristics: can make ice, keep fresh, refrigerate rapidly, large or small, segmented temperature control, anti -bumps, tilt, exemption of maintenance, and not easy to damage.
Insurance: Generally, only the refrigeration function, the weight of the product is heavier and the price is higher, which is more than 10 times that of the same volume of semiconductor refrigerators.
Common problems and solutions for car refrigerators
1. Refrigerator noise
The problem of high noise in the semiconductor refrigerator is generally on the fan. Fan directly affects the refrigeration effect of the semiconductor refrigerator. If it is not in place in terms of fan speed positioning and detail processing, there will be a problem with large noise.The sound of the compressor refrigerator is definitely relatively large, but there are also a compressor refrigerator that has done well in the compressors noise reduction technology. The first standard of the refrigerator of the compressor is that the noise is small.When you find noise, check the fan first. The fan aging noise is naturally large; followed by checking the compressor (if there is a compressor), the compressor sound is abnormal, you must find the manufacturer to repairs.
Choosing a low -noise car refrigerator can not only improve the quality of life of car travel, but also embellish the quality of the home bedroom, because in addition to the car refrigerator, it can also be used as a supplement to the home refrigerator. It is used in bedrooms and living rooms.
2. Not refrigeration
For semiconductor refrigerators, first check whether the fan is running; second, check the product current.If you are close to 5 ampel, you can say that Parls post, PCB or insurance switch is fine; if there is no current, check the voltage at the connection of the Parca sticker component on the PCB.Then, if you display 12V or higher, then the PCB and the temperature fuse are good. It is recommended to replace the Parra post.If there is no voltage, the inspection fuse is determined to be PCB or the fuse is broken.If these aspects are checked, you have to find the manufacturer to repairs.Of course, to check these projects, you must have tools, no tools, and can only be anxious.The compressor refrigerator is not recommended to check in depth, because the technology of the compressor is more complicated.
3. The machine keeps refrigeration without stopping
This situation mainly appears on the customers of online shopping. Because when the online shopping mailing, the courier company is not responsible, and the things are fell sharply, causing the box to break.Can only keep cooling.If the crack is not large, you can seal it by yourself.If the crack is too large, you must find a manufacturer to repairs without scrap.So remind friends who buy online to check carefully when receiving the goods. Do not feel that the face -to -face inspection in front of the delivery is a distrust of him. In fact, this is completely the protection of his rights and interests.
4, more power consumption
Unless you buy cheap or imitation, the products of regular brands have focused on the problem of power consumption when designing and production, and generally it will not be high.Another reason is that the refrigerator does not have a low voltage protection device. After the car is turned off, you forget to turn off the refrigerator power supply. The refrigerator has been working, and the electricity on the car battery has been consumed.It is recommended to buy a car refrigerator with a low -voltage protection device, or buy a voltage protection device, or remember to power the refrigerator directly after parking.
5. The actual temperature does not match the display temperature
For users who use car refrigerators to transport medical preparations, because of high temperature requirements, it is best to determine the temperature in the box before forming a car refrigerator.However, it should be noted that the temperature displayed on the refrigerator display is not necessarily consistent with the temperature determined during the thermometer, because the determination point position is different.Just like the home refrigerator, the temperature on the door is different from the temperature of the inner wall of the refrigerator.
How to buy a car refrigerator
Dependent
If it is installed between the main and co-driver seats, be sure to choose the upside-down car refrigerator with a volume of about 3.5-4 liters. If you need a larger car refrigerator, you can put it in the trunk of the car, and the volume can reach up to 60 liters.
Look at the appearance
When buying, consider whether the color and style of the car refrigerator and style are coordinated with the decoration of the car instead of simply choosing a fashionable, beautiful and generous car refrigerator.
Deepen
Although the electricity consumption of the car refrigerator itself is not large, basically do not have to worry about power off the road halfway, it is recommended to buy a car refrigerator that can automatically power off. Once the electricity is not enough, it will automatically cut off the power to effectively protect the car.Battery.
Look at details
Open the refrigerator lid and try the feel of the sealing strip. If it lacks toughness and strict rectification, just close the lid to see the flaw from the appearance, and the actual sealing effect will not be good.
