1、 Transport cold and fresh food to ensure its freshness. The main function of a refrigerated truck is to keep fresh and cold food. This type of truck is specifically designed for transporting food, and its internal hygiene meets standards. It can also have the effect of inhibiting microbial growth.

For example, transporting fresh foods, seafood, vegetables, etc. can achieve good results. In addition, some refrigerated trucks also have temperature control functions, which can adjust the temperature according to the specific requirements of the food, achieving the best preservation effect.

2、 Transport other medicines to ensure their efficacy. Some medicines require lower temperatures to ensure efficacy, and they have strict requirements for storage temperature. Specialized cold chain trucks are required for storage and transportation of these medicines.

The car should undergo strict disinfection before storing the medicine inside. If the transportation road is relatively far, it is necessary to adjust the temperature appropriately to ensure the safe transportation of drugs.

3、 Transport cold drinks to ensure they do not melt. The demand for refrigerated trucks for delivering cold drinks is even more widespread, especially in summer when large quantities of transportation are required.

Generally, it is loaded directly from the cold drink factory and then transported to the cold storage of various sub distributors. Of course, vehicles transporting cold drinks also need to go through disinfection, but transporting cold drinks requires a larger capacity for the vehicle and requires large refrigerated trucks to complete the transportation task.

4、 Transport items that require quality assurance to achieve short-term preservation and quality assurance. There are also other items that need to be transported by refrigerated trucks, such as chemical products, materials for the biopharmaceutical industry, and so on. However, these are relatively niche demands, and the quantity usually shipped is not very large.

The principle of cold plate refrigeration is to use the stored cold capacity of the refrigerant (refrigerant) after freezing for refrigeration. Before transportation, the refrigerant in the cold plate inside the compartment is first "charged" to cool and freeze it. Then, during transportation, the refrigerant in the cold plate is used to melt and absorb heat, keeping the temperature inside the compartment within the appropriate temperature range for the transported goods. Therefore, the cold plate is also known as the "cold storage plate".

The structural types of cold plate refrigeration devices are divided into integral and split types. The integrated power unit, refrigeration unit, and cold storage plate are all placed on the vehicle; The split type vehicle is only equipped with a refrigeration unit and a cold storage plate.

When parking, use the ground mounted power device to drive the refrigeration unit to "charge" the cold storage plate. The latter is often used in practical applications. The commonly used cold storage agents are low melting point eutectic solutions, whose melting point is usually about 10 ℃ lower than the suitable temperature inside the chamber. When the suitable temperature for transporting goods changes, the composition of the eutectic solution used also needs to change accordingly.
