Compared with the selection of general truck chassis, refrigerated trucks in Chongqing also need to consider the stability of the chassis. The goods transported by refrigerated trucks are generally not items stored for a long time. Even with refrigeration equipment, they still need to be quickly transported to their destination. At the same time, refrigerated goods also have higher requirements for the transportation environment. If there is a malfunction on the road that causes the goods to deteriorate, the losses will be very significant.

The compartment of a refrigerated truck is different from that of a typical box truck. It requires good sealing function and insulation to ensure that refrigerated items are in a stable temperature environment.

The design of refrigerated trucks mainly focuses on sealing and insulation functions. The structure of refrigerated trucks generally uses a three-layer structure, and the surface skin is made of composite materials such as fiberglass, color steel plates, aluminum alloys, and other raw materials.

The raw materials for the inner panel should be transported for different goods and different materials should be used. Stainless steel plates should be used for the inner panel. The intermediate layer is made of insulation material, mainly using polyurethane foam material. The glass panel and polyurethane foam plastic are bonded together with high-strength adhesive around to form a closed panel.

In addition to the material, the thickness of the cargo hold also determines the insulation effect. The thicker the insulation layer of the cargo hold, the better the insulation effect. However, the space inside the cargo hold will be reduced, and the load capacity of the cargo will also be reduced. Users need to choose the appropriate thickness according to their actual needs.

Among the three components of a refrigerated truck, the refrigeration unit is an important component. Due to the small cargo space, there are also high technical requirements for temperature control. Good goods are not cheap, and the price of imported refrigerators is also very expensive, like a set of imported refrigerators, new ones can be as cheap as tens of thousands. In contrast, domestic brands have a clear advantage in terms of price. For users who value price, domestic brands are also a good choice.

The power source of a refrigeration machine can be divided into independent units and independent units. An independent unit has an independent power source, and the unit itself has an independent diesel engine as its power source. The power output of non independent units is driven by the engine of the car chassis.

If the cost difference between non independent refrigeration units and independent refrigeration units is over tens of thousands, and the budget is relatively surplus and the temperature requirements for the cabin are lower, it is recommended to use them independently.
