Car Refrigerator

Car refrigerator refers to the refrigerator that can be carried on the car. Car refrigerator is a new generation of refrigeration and refrigeration appliances popular in the international market in recent years. On board refrigerator refers to the refrigerator and refrigerator that can adapt to the working environment of cars, ships and other vehicles by using the power supply system on cars and other vehicles.

There are mainly two kinds of on-board refrigerators on the market. One is semiconductor on-board refrigerator, which is cooled by electronic chips; The other is the compressor on-board refrigerator. The compressor is the traditional technology of the traditional refrigerator

The principle of semiconductor on-board refrigerator is that it is cooled by electronic chips and uses the P-N structure composed of special semiconductor materials to form thermonuclear pairs to produce Pettier effect, that is, a new refrigeration method through DC refrigeration. The refrigeration temperature range is 5 to 65 degrees. This method has the advantages of both refrigeration and heating, environmental protection, no pollution, small volume, low cost, no vibration, noise and long service life. The disadvantage is that the refrigeration efficiency is not high and the capacity is small.

The compressor is the traditional technology of the traditional refrigerator. The refrigeration temperature is - 18 ℃ and 10 ℃. With high refrigeration efficiency and large volume, it is the mainstream development direction of vehicle refrigerator in the future. The disadvantages are heavy weight, power consumption and high price.

The compressor on-board refrigerator is composed of compressor, condenser, drying filter, capillary, evaporator and other components. The power comes from the compressor, the drying filter is used to filter dirt and dry water, the capillary is used to throttle and depressurize, and the heat ex-changer is the condenser and evaporator.

Compressor on-board refrigerators are similar to household refrigerators. They are cooled by compressor power. The refrigeration is fast and strong. The refrigeration can reach - 18 ℃, which can make ice and keep fresh. The volume can be large or small, the temperature can be controlled in sections, and it is not easy to be damaged. It is the mainstream direction of the development of on-board refrigerators in the future. The compressor refrigerator can be used in vehicles or at home through the power converter, which is the extension and supplement of the household refrigerator

The heart of compressor refrigeration is compressor. Compressor is a driven fluid machinery that promotes low-pressure gas to high-pressure gas. It is the heart of refrigeration system. It sucks low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through motor operation, and then discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle, so as to realize the refrigeration cycle of compression → condensation (heat release) → expansion → evaporation (heat absorption).

1. For use in cars, the cigarette lighter is connected.

2. When switching from heating function to refrigeration function, it is recommended to turn off the power and start the car refrigerator after 5 minutes.

3. Please ensure that the air vent and cooling hole of the car refrigerator are unblocked at any time.

4. Do not plug articles into the cooling hole and suction hole of the car refrigerator, and keep away from the heat source when using the car refrigerator.

5. When cleaning the car refrigerator, please turn off all power and do not use strong detergent to clean the refrigerator.

1. Operating ambient temperature of refrigerator: the higher the ambient temperature, the shorter the battery life;

2. Type and quantity of items stored in the refrigerator: the more items, the more power the refrigerator needs to consume to maintain the set temperature;

3. Times of opening and closing the door: the door is opened and closed frequently, and the power consumption of the refrigerator increases;

4. Capacity and power status of automobile battery: the larger the battery capacity, the longer the service time; The more sufficient the power, the longer the service time;

5. Setting temperature of refrigerator: the lower the setting temperature, the greater the power consumption;

6. Setting level of refrigerator battery protection: the higher the battery protection level, the shorter the service time;
