With the improvement of living standards and changes in lifestyles, people's demand for quick-frozen, fresh food, milk, flowers and other foods is increasing. The refrigerated carriage plays a vital role in the transportation process. It is not only the key equipment of the refrigerated truck, but also the key to ensuring the freshness of perishable food during transportation.
Compared with ordinary trucks, what is special about refrigerated trucks? Here is a simple classification for everyone. From the structural point of view, refrigerated trucks can generally be divided into three parts: insulation compartment, automobile chassis, and refrigeration unit.
Insulated compartment:
1.The refrigerated truck compartment is different from ordinary trucks. It has good sealing and heat insulation properties to ensure that refrigerated products are in a stable temperature environment. The design of the carriage mainly focuses on airtightness, heat insulation and light weight. The structure of the compartment board generally adopts a three-layer structure, and the inner and outer skins are made of high-quality fiberglass and fiber felt materials.
The material of the inner plate varies according to the goods being transported. The most expensive inner plate is stainless steel.
The intermediate material is heat insulation material, mainly flame-retardant polymer polyurethane material.
The box board is generally made by wet bonding method, heated and pressurized by special laminator equipment, and pressed into a closed, organic whole at one time.
In addition to materials, the thickness of the compartment board also determines the quality of the insulation effect. The thicker the insulation layer of the compartment board, the better the insulation effect, but the internal space in the compartment is reduced and the cargo load is reduced. Users should choose according to their actual needs. Appropriate thickness.
Choose the corresponding box according to the transported items. For example, refrigerated trucks for transporting cold and fresh meat require customized meat hanging slides; refrigerated trucks for transporting a variety of items to stores, with small batches and many varieties, require multi-temperature refrigerated trucks.
Choose the corresponding compartment according to the required temperature of the item. If the small shop is transported to and fro frequent loading and unloading, the door needs to be opened frequently, and the required car body is also different.
2.Chassis:
When choosing a chassis for a refrigerated truck, it is necessary to consider the structure and carrying capacity of the chassis, fuel-saving performance, and emission standards according to the tonnage and road conditions of the cargo.
Compared with ordinary truck chassis, the stability of refrigerated trucks needs to be considered. The quality of the transportation environment has a relatively large impact on the refrigerated trucks. If the goods are left for a long time due to road failures and lead to deterioration of the goods, the loss will be very huge.
3.Transport Refrigeration unit
According to the source of power, it can be divided into non-independent units and independent units. The non-independent refrigeration unit does not have an engine, and the compressor is driven by the vehicle's own engine. The independent refrigeration unit has its own engine and does not need to be driven by the vehicle's engine.
There is also a unit drive that does not use a belt system, but transmits power through an electric system. This type of unit is called an all-electric unit. This unit has low fuel consumption, stable performance and simple maintenance. It is the most advanced product in the industry.
These three types of units have their own advantages and disadvantages, and users can choose according to their own needs.
The model size of the refrigeration unit needs to be determined according to the type of goods to be transported, the size of the insulation compartment, the thermal conductivity of the insulation material, the set temperature value in the compartment, and the use area of the vehicle, so as to ensure the cooling capacity of the unit, but also It can meet the temperature requirements in the carriage and avoid the waste of resources due to excessive cooling capacity.
