A good Chongqing refrigerated truck should have good insulation performance, light weight, and sturdy structure. Of course, there are other aspects that can be compared.

1. Insulation function

The thermal insulation performance of insulated compartments is closely related to their structure. Therefore, when selecting insulation compartments, it is important to first consider the thermal conductivity of the insulation material itself and whether the filling material is dense. Now the insulation material is foamed PU, look at the container.

Whether the insulation layer inside the board is sealed, the whole board is filled with foam, and the insulation layer inside the whole board is combined into one. The sandwich bonding manufacturing method selected is far from achieving the integrity of the insulation material inside the car body. It depends on whether there is a metal thermal bridge. The fourth is whether the board connection is tight and seamless, and the door mouth sealing function. Good insulation function means long insulation time, short working time for the refrigerator to reach the same temperature, and reduced fuel consumption, playing a role in energy conservation and emission reduction.

2. Lightweight and sturdy structure

The weight of a car will consume more fuel during transportation, whereas if the car is light, it will consume less fuel during transportation. The insulation layer of the refrigerated truck is made of foamed polyurethane, the interior and exterior of the car are made of fiberglass, and the body coating is also made of lightweight aluminum. The structural strength is also much higher.

3. Corrosion resistance

A good insulated compartment should be made of fiberglass sheet

Some insulation compartments use colored coated steel plates on both the outer and inner surfaces. Experiments have shown that the anti-corrosion ability of FRP is 3-5 times that of general metal materials, and it is easy to modify. Therefore, the service life of insulated refrigerated containers will be greatly extended, and the service life of good insulated carriages can reach 15 or even 20 years.

However, if the structure of the body insulation board itself is unreasonable, such as the sandwich bonding method, the adhesive will age over time, and the body insulation layer and the body inner and outer skins will simply delaminate, which not only greatly reduces the insulation effect, but also simply reduces the water absorption of the foam insulation layer while breeding microorganisms and reducing food quality security.
