Most refrigerated trucks are used to transport goods. When choosing a refrigerated truck, they must first look at the chassis of the car. According to the weight of the cargo and the condition of the road through which it was transported, consider what kind of structure and carrying capacity of the chassis. Goods transported by refrigerated trucks are generally items that cannot be stored for a long time. Although they are equipped with refrigeration equipment, they need to be delivered to their destinations quickly. Therefore, it is necessary to consider the stability of the chassis and prevent the occurrence of failures during transportation. The long time causes the goods to deteriorate and cause losses. The cargo compartment of a refrigerated truck is different from an ordinary van truck. In order to ensure that the cargo is transported at a stable temperature, the tightness and thermal insulation performance of the cabin are better. When selecting the three-layer structure, the inner and outer skins are made of composite materials such as glass fiber reinforced plastic, color steel tile, and aluminum alloy, and the middle inner plate is preferably made of stainless steel. The thickness of the cargo compartment also determines whether the insulation effect is good or bad. The insulation layer is mainly made of polyurethane foam material. The thicker the filling, the better the insulation effect. The drawback is that the space inside the cargo compartment will be reduced and the cargo load will be reduced. The most important is the choice of the refrigeration unit and the two components of the freezer: independent units and non-independent units. The independent unit is powered by a separate diesel engine; the non-independent units rely on the car's own engine to drive refrigeration. In terms of cost, there is a big difference between the prices of the two units. If the budget is sufficient, and the temperature control in the cargo room is rather strict, independent refrigeration units are recommended; otherwise, non-independent units are selected. Some of the imported refrigeration units are very expensive, compared with domestic brands with much higher price/performance ratios. Choosing a domestically-branded refrigeration unit with a good quality is also a good choice in terms of cost.
