From a structural perspective, refrigerated trucks can be divided into three parts: chassis, insulation room, and refrigeration unit.

To drive on highways, the chassis of a car is an essential part of the foundation. As a whole, refrigerated trucks mainly come in two forms: bicycles and trailers, depending on the tonnage and demand of the loaded goods.

Short distance delivery and loading between urban areas or counties are generally less common, and there are more options for light truck chassis. However, for long-distance transportation with larger transport volumes, heavy trucks or semi trailers in the form of refrigerated trucks are preferred.

The materials for refrigerators in the market are generally divided into two types: color steel+polystyrene board, and fiberglass+polyurethane.

In terms of insulation materials, polyurethane with the same thickness has better insulation effect than polystyrene board and is cheaper, making it the main material used in many low-priced refrigerated trucks. If users use refrigerated trucks to transport goods that require low temperatures, such as fresh meat, frozen goods, ice cream, etc., they cannot deceive refrigerated trucks into offering low prices.

Once they choose low-priced polystyrene board refrigerated trucks, they cannot reach the ideal temperature and greatly increase energy consumption, with losses greater than losses.

From the perspective of the inner and outer panels, color steel plates are prone to creating cold bridge insulation chambers, which can affect the insulation effect during operation. Fiberglass steel plate is much better than color steel plate. Not only does it have strong impact resistance, but it has also been widely recognized in the market.

A refrigerated truck is equipped with a refrigeration system and insulated compartments for freezing and preservation. Through refrigeration, the temperature inside the truck is always below the predetermined temperature. It is often used for transporting frozen food, dairy products, vegetables and fruits, and is an important and difficult to control link in the cold chain; Can engage in short, medium, and long-distance transportation. Tonnage is mainly medium and large, supplemented by light and small.

Insulated trucks only have insulated compartments and no refrigeration units, equivalent to a simple version of refrigerated trucks; Commonly used for transporting perishable goods such as milk, cake dairy products, ice cream, fruits and vegetables, frozen meat, fresh meat, cold drinks, etc. Usually only used for short distance transportation. The tonnage is mainly small and light, supplemented by medium.
