TEN MISUNDERSTANDINGS OF CAR REFRIGERATOR REFRIGERATOR

We are a car fridge freezer manufacturers. Let me explain to you the top ten misunderstandings of car refrigerator refrigerators.

　　1. The refrigerator can reduce the temperature of the goods to the lower limit of the temperature of the refrigerator.

　　The role of the box is to keep heat, and the role of the refrigerator is to ensure that the temperature of the goods in the box remains unchanged, and it cannot ensure that the temperature of the goods is reduced. For example, some customers who pull the meat directly put the meat of the animal that has just been slaughtered into the box, and the temperature of the refrigerator can not be beaten. This is the reason. The refrigerator can easily knock down the temperature of the air, but it is difficult to knock down the temperature of the cargo, because the specific heat value of the cargo is close to 1000 times that of the air.

　　2. Goods with low temperature are difficult to hit, and goods with high temperature are easy to cool down?

　　The temperature of the ice cream is controlled at -18 degrees, this temperature is easy to beat. On the contrary, Mengniu’s probiotic milk, fruits, vegetables, and yeast are hard to beat the temperature of their own heat-generating items. If the temperature of the box is hit, the temperature of the goods may not necessarily drop. Mengniu's probiotic milk can only be controlled at about -4 degrees and the temperature in the probiotic cup can be controlled at about 4 degrees. This is the case.

　　3. The less goods, the better the temperature?

　　The less the cargo, the greater the volume of air in the box, which is one of the reasons why Mengniu’s probiotic milk is difficult to beat. Reasons: 1) The volume of air is too large for half-cargo cargo. 2) The goods themselves ferment to produce heat.

　　4. Can the refrigerator with good quality blow out the mist in the box?

　　The main reason for the fogging is too much water in the box or poor drainage of the refrigerator, which is not a good phenomenon. It can be judged by looking at the thermometer. It can also be judged by the water outlet on the outside of the refrigeration cabinet. It is normal if there is continuous water flowing out of the cabinet during the warming process, otherwise the artesian water port is blocked.

　　5. Is the refrigerator exposed to the sun to warm it up?

　　The higher the ambient temperature outside the cabinet, the worse the cooling effect. For example, 1) The refrigerator is exposed to the sun for a long time. 2) The short-term weather with a high temperature of 40 degrees in summer has a severe test on the refrigerator, and many problems will arise in refrigeration.

　　6. The temperature on the display of the refrigerator does not reach the temperature required by the goods, and the refrigerator is playing a negative role.

　　The temperature of ice cream out of the warehouse is -18 degrees. Pack it and turn on the refrigerator. The display temperature is 2-3 degrees, or even 7-8 degrees. This is the temperature of the air in the cargo box. As the refrigeration continues, the temperature of the display also drops. Some refrigerators can reach -18 degrees, and some refrigerators cannot reach -18 degrees, such as -13 degrees. There is no problem with the quality of the same goods.

　　7. The temperature of the refrigerator display is rising, which proves that the temperature of the cargo is rising.

　　The temperature of the display only represents the temperature of the air between the packaging in the box, not the temperature of the goods. The specific heat value of the air is very low, which can easily cause the temperature to rise, but does not mean that the temperature of the goods rises.

　　8. The larger the cooling capacity of the refrigerator, the better.

　　The advantage of large refrigeration capacity is that the temperature of the cabinet is fast, the pressure in the compressor system drops quickly, and the horsepower of the engine is low. But the disadvantage is that the power consumption of the battery is relatively large, and the battery often loses electricity and cannot start to fire. This is especially true for diesel vehicles. The good principle of installing refrigerators in refrigerated trucks is to match, and it is not good to be large or small.

　　9.The refrigerating capacity of the domestically-made A refrigerating machine is larger than that of the imported B refrigerating machine.

　　There is no way to match the cooling capacity of the coolers with different sizes of cabinets, and it is not a level.

　　10. The insulation of the cabinet is not important, as long as it matches with a good cooler
