Refrigerated truck
A refrigerated truck is a closed box type transport vehicle used to transport frozen or fresh goods. It is a specialized refrigerated transport vehicle equipped with a refrigeration unit and a polyurethane insulated compartment. It is commonly used to transport frozen food (refrigerated truck), dairy products (dairy transport truck), vegetables and fruits (fresh goods transport truck), vaccines and drugs (vaccine transport truck), etc.

structure
A refrigerated truck is composed of the walking part of a dedicated vehicle chassis, as well as insulation and thermal insulation compartment (usually made of polyurethane material, fiberglass, color steel plate, stainless steel, etc.), refrigeration unit, temperature recorder for refrigerated trucks inside the compartment, and other components. For vehicles with special requirements, such as meat hook trucks, optional accessories such as meat hooks, waist guards, aluminum alloy guide rails, ventilation ducts, etc. can be installed.
Manufacturing Technology of Refrigerated Carriage Body
1. The "sandwich" panel adhesive type assembled in pieces is currently used by large refrigerated truck manufacturers in China, and the refrigerated trucks produced using this technology have high thermal insulation performance.
2. Injection foam type assembled in sections.
3. The overall skeleton is injected with foam.
4. Vacuum adsorption adhesive
Classification of refrigeration units:
Refrigeration units are divided into non independent refrigeration units and independent refrigeration units. Domestic and imported units, etc. Most car models use external refrigeration units, while a few micro refrigerated trucks use internal refrigeration units. For refrigerated trucks with lower temperature requirements, a built-in cold plate (equivalent to an evaporator) can be used in the compartment.
Classified by chassis carrying capacity: micro refrigerated truck, small refrigerated truck, medium refrigerated truck, large refrigerated truck
Classified by carriage type: bread refrigerated truck, box refrigerated truck, semi-trailer refrigerated truck
Important equipment

Refrigerated truck refrigeration unit
Refrigerated truck refrigeration unit: an important equipment that provides a continuous supply of "cold" for refrigerated truck containers. It is usually installed at the top of the front of the container and has an air conditioning like appearance, but has stronger cooling capacity than air conditioners of the same volume.
Refrigeration units are generally divided into two types: independent units and non independent units. The difference is that independent units rely entirely on another unit to generate electricity and maintain operation, while non independent units rely entirely on the engine operation of the entire vehicle to drive the cooling work of the unit.
Selection of refrigeration units for refrigerated trucks.
Generally, different power refrigeration units are selected based on the volume of the refrigerated compartment and the temperature requirements of the transported goods.
