In fact, refrigerated trucks are not used to refrigerate goods, but mainly to maintain the temperature of the goods, rather than lowering the temperature of the goods. The power of the refrigerator equipped with the vehicle depends on the size of the refrigerator, the temperature requirements of the product, the insulation of the cabinet and the ambient temperature. In general, refrigerators for refrigerated trucks in a specific area are standard. We choose the size of the car, which corresponds to the corresponding temperature of the refrigerator. However, in the case of high quality of goods and high requirements for cold chain control, a higher level of chiller configuration can be selected.

At present, the refrigeration mode of refrigerated trucks is mainly divided into independent vehicle engine refrigeration, cold plate refrigeration, external power supply refrigeration, and compressed gas refrigeration. External power supply cooling is mainly used for shipping refrigeration containers, and compressed gas refrigeration is used in part on Japanese refrigerated vehicles. In China's road refrigerated trucks, there are mainly two forms of independent vehicle engine refrigeration and cold plate refrigeration. The application of the independent vehicle engine cooling form is more common, and its advantage is that it is not limited by time and transportation distance, and can be adjusted in different temperature ranges. The advantage of cold plate cooling is that the temperature inside the car is relatively stable, the cargo can be unloaded multiple times and there is no risk of engine damage on the way, but the disadvantage is that the temperature range is narrow, and the waiting time for cooling and the transportation cannot be carried out.
