Chongqing refrigerated trucks mainly come in two forms: single bikes and trailers. For vehicles used for short distance delivery or loading of goods between urban areas and districts, refrigerated trucks with medium and light truck chassis can be selected.

When engaged in long-distance transportation, if the transportation volume is large, medium and heavy-duty vehicles or refrigerated trucks in the form of semi trailers need to be selected.

The main components that affect the performance of refrigerated trucks are the chassis, insulated compartment, and refrigeration unit. Only when the quality of these three parts is up to standard can the refrigerated truck reliably and stably perform during transportation.

Compared with ordinary truck chassis, choosing a refrigerated truck manufacturer requires a focus on the stability of the chassis. The goods transported by refrigerated trucks are usually items that cannot be stored for a long time and need to be delivered to the destination in a shorter period of time.

Refrigerated goods have higher requirements for transportation environment. If there is a malfunction during transportation, the delay time will cause the goods to deteriorate and result in losses. Therefore, when choosing a refrigerated truck, a light truck chassis can be chosen for short distance transportation, and a medium to heavy truck chassis or a tractor semi-trailer chassis should be chosen for medium to long distance transportation or large transportation volume.

At the same time, the advantages of imported car chassis are low maintenance rate, good handling, and fuel efficiency, but the price is high. The advantage of domestic car chassis is that it is cheap, but there are more minor problems. Therefore, when selecting a car chassis, users need to comprehensively consider the structure and load-bearing capacity of the chassis based on factors such as cargo tonnage, road conditions, and personal strength.

The refrigerated truck compartment is different from ordinary box trucks and requires good insulation and sealing performance to ensure that refrigerated goods are in a stable temperature environment during transportation.

The choice of compartment is related to the specific goods being transported, for example, refrigerated trucks transporting fresh meat need to customize hooks on the compartment; When delivering goods to stores, small batches and a variety of goods require refrigerated trucks with multiple temperature layers.

When temperature requirements vary and loading and unloading are frequent, refrigerated trucks with multiple doors are needed. Users can customize the cabin manufacturing factory according to their specific needs. Of course, the cargo box of a regular box truck can also be converted into a refrigerated container, but it is not recommended to use a regular cargo box to convert into a refrigerated container.

In fact, using a refrigerated compartment directly is cost-effective because the cargo compartment is usually made of iron or steel, which has poor insulation effect and is prone to rusting. If seafood products are pulled, seawater will corrode the compartment.

But regular refrigerated carriages have air tightness and insulation, usually using a three-layer structure, with composite materials such as fiberglass, color steel plates, aluminum alloys, etc. for the inner and outer skin.

The material of the inner plate varies depending on the transported goods, usually stainless steel plate; The intermediate layer is made of insulation material, mainly polyurethane foam material; High strength adhesive is used on the four sides to bond the glass plate with polyurethane foam material, which is not easy to rust.

In the selection of refrigeration units, non independent refrigeration units are cheaper and easier to maintain, but they do not have a power unit and rely on the car engine to drive the compressor. Due to the influence of the working condition of the car engine, their performance is not as good as independent units.

The independent refrigeration unit itself has an engine and generator device that can provide power and electrical energy for the refrigeration system. It can work independently and is not limited by the working state of the car engine. The performance is relatively stable, but the price is high and the accessories are expensive.

Therefore, when selecting a unit, the length of transportation distance should be considered comprehensively. For short distance delivery within the city or between districts and counties, and if the carriage is less than 7 meters, it is recommended to use non independent units.

When conducting long-distance transportation and the carriage is over 7 meters long, it is recommended to use an independent refrigeration unit. This way, even if the car engine stops working during transportation, the refrigeration unit can still cool normally, reducing the quality loss of the transported goods.
