|How to choose a refrigerated truck refrigeration unit?|
In recent years, the development of cold chain logistics has been very rapid, and refrigerated trucks are a very important part of cold chain transportation. Therefore, the use of refrigerated trucks has been greatly improved. The composition of refrigerated trucks is mainly composed of chassis and top loading compartments. , The refrigeration unit consists of these three parts. Before buying a refrigerated truck, many friends will have this question, that is, how to choose a refrigeration unit?
As the name implies, an independent refrigeration unit means that the refrigeration unit has a separate power source and can work independently without being restricted by the working state of the engine. A non-independent refrigeration unit means that the unit itself has no power unit and cannot work alone. It must rely on the engine to drive compression. Machine to work.
2. Choose according to the length of the carriage.
Depending on the size of the refrigerated car body, an independent refrigeration unit or a non-independent refrigeration unit is selected. From the perspective of the market, refrigerated trucks with a body of less than 6 meters and a container volume of 4-31 cubic meters have more options for non-independent units. For refrigerated trucks with a body of more than 6 meters, choose independent units; according to different vehicles, such as trucks and trailers, the independent refrigeration units are different. For trucks, medium-sized independent refrigeration units are used; semi-trailers are mostly large-scale refrigeration units. It is our common refrigeration unit arranged in front of the trailer. Of course, it is not to say that the 6-meter car body is an absolute limit line. It also depends on the requirements of each of your different goods. You can choose flexibly according to your needs. After all, the best for you is the best.
3. Choose according to the temperature requirements of the goods being shipped.
Different goods have different requirements for temperature, and the corresponding cold machine power is also different. For example, the delivery of ice cream and other frozen foods generally requires a low temperature of minus 18 degrees, and the transportation of cold meat requires a temperature of minus 5 degrees. Different fresh fruits and vegetables require different temperatures.
Especially the cold chain transportation of vaccines and medicines with special requirements for transportation temperature. Therefore, you can choose a cryogenic unit or a fresh-keeping unit according to the temperature requirements of the goods. In addition, some goods require the refrigeration unit to have a defrost function during transportation. This should be clearly understood when choosing.
4. Choose according to transportation mileage.
The transport mileage also has requirements for the type of cooler. The non-independent refrigeration unit is more suitable for short-distance transportation in towns, and the short distance is lower in cost, and this matches the second choice of cooler based on the length of the carriage. It is also suitable for short-distance transportation in town Basically, carriages below 6 meters are used more often. For long-distance transportation, the non-independent refrigeration unit is more suitable, even if the engine stops working during the loading and unloading rest, the refrigeration unit can work normally.
