Refrigerated trucks are mainly enclosed special transport vehicles used to transport frozen or preserved food. Besides good refrigerating effect, its also has a good preservation effect on some foods that need to be refrigerated (such as frozen food, dairy products, vegetables and fruits). And it can ensure the safety of the food.
Inner structure of the compartment is of excellent sealing performance, and heat insulation and heat preservation effect, so people can conduct refrigerated transport according to different foods. Refrigerated truck can ensure the fresh taste and flavor of the food during consuming, it brings people health and safety.

Main material list of insulation compartment parts
The front wall, the roof, the left and right panels are all "sandwich" plate structures. Sheets are all treated with overall compression and their overall strength of the sheets reach international standards. For sheet cutting, CNC gantry milling machine is adopted to ensure precision parameters of each component.
| Type and thickness of the sheet (mm): | Sandwich composite sandwich plate | ||
| Outer covering | Inner covering | Insulation layer (plate) thickness | |
| Roof: | Aluminum alloy flat plate | FRP flat plate | 100mm polyurethane foam |
| Side plate: | Aluminum alloy flat plate | Aluminum alloy flat plate | 80mm polyurethane foam |
| Front wall: | Aluminum alloy flat plate | Aluminum alloy flat plate | 100mm polyurethane foam |
| Rear door: | Aluminum alloy flat plate | Aluminum alloy flat plate | 80mm polyurethane foam |
| Bottom plate: | Bamboo plywood | FRPplate | 80mm polyurethane foam |
| Floor: | A 2.5 mm pattern aluminum alloy plate is laid on the bamboo plywood. | ||
The large sandwich plate made by vacuum negative pressure technology and first-class equipment fully guarantees the thermal insulation and a certain strength.
II, Scientific internal structure
The unique ventilation slot design improves the circulation speed, which can increase the ventilation area by 30%, realize rapid circulation ventilation, quickly reduce the temperature in the cabin, and there is no dead angle of temperature difference, which effectively achieves energy saving.
III : Excellent sealing performance
Polyurethane spraying increases the thickness of the insulation layer. The secondary foaming technology is a deep processing technology for spraying the gap on the basis of the sandwich board insulation layer. The use of the secondary foaming technology effectively fills the cavity formed by the splicing of the sandwich plates, and better handles the installation gaps and manufacturing errors, and further enhances the insulation performance.
Design of back door and door frame:
Decomposition diagram
Design of back door and door frame allows it can be open at 270 degree. Material of the door bracket is a 2.5-millimetre-thick stainless steel sheet, which enhances rain and dust proof. The bracket and the carriage is connected with rivets . ABS calcium plastic material are put among the back door bracket and other plates to avoid the cold bridge.
The plate clamp the labyrinth tape consist the back door structure. The labyrinth type can offer multiple layers of protection to avoid the cold air leakage.
The back door is still a sandwich plates structure. The inner layer is a 12 -millimetre-thick water prof plywood. It is durable and will not go rot. Inside of the plywood uses polyurethane to keep warm. The back door is enclosed with several layers of labyrinth tape to keep the leakage ratio h-1 less than or equal to 1.2.
IV: Brand refrigeration unit
The truck is equipped with Thermo King refrigerating unit KV300. Since 1938, products and components from Thermo King have become the standards of the world's transport temperature control industry. As the leader of world's refrigerating transport system, Thermo King provides solutions for global transport temperature control industry. Its major markets are refrigerating transport of temperature sensitive products, public transport and temperature control for public vehicle, long and short distance land refrigerating transport and sea refrigerating transport.

VI: standby power SUPPLY
The standby power system of the refrigerator is the second source of refrigerating power when the engine of the vehicle is not working or fails. Through the standby power system with external power supply, the compressor can also keep the temperature inside the carriage and keep the goods fresh. It can be used as a temporary refrigeration solution to solve some emergencies, or as a temporary refrigerator. The standby power supplies begin to come into play when the driver need rest in transportation or when the goods arrives without being unloaded in time. It continues to supply the power required by the refrigerating truck through the standby power compressor when the engine is truck is off. It can keep the goods in the best condition in a constant temperature environment and it also can play a good role for some goods with high requirement of temperature.
