Refrigerator truck is a closed van transport vehicle used to transport frozen or fresh-keeping goods. It is a refrigerated special transport vehicle equipped with a refrigeration unit and a polyurethane insulated compartment. It is often used to transport frozen food (refrigerator truck). ), dairy products (dairy transport truck), vegetables and fruits (fresh goods transport truck), vaccines and medicines (vaccine transport truck), etc.
structure
The refrigerated truck is composed of the traveling part of a special car chassis, the heat-insulating compartment (generally made of polyurethane materials, fiberglass, color steel plates, stainless steel, etc.), the refrigeration unit, the refrigerated truck temperature recorder in the compartment and other components. For special requirements Vehicles, such as meat hook trucks, can be equipped with optional parts such as meat hooks, waist rails, aluminum alloy guide rails, and ventilation slots.
Refrigerated carriage body manufacturing technology
1. The "sandwich" board assembly type is bonded. Currently, all the larger refrigerated truck manufacturers in China adopt this technology. The refrigerated trucks produced using this technology have higher thermal insulation performance.
2. Injection foaming type assembled in pieces.
3. The overall skeleton is injected with foaming type.
4. Vacuum adsorption type pasting
Refrigeration unit classification:
Refrigeration units are divided into non-independent refrigeration units and independent refrigeration units. Domestic units and imported units, etc. Most models use external refrigeration machines, while a few mini refrigerated trucks use built-in refrigeration machines. For refrigerated trucks with lower temperature requirements, a built-in cold plate (functionally equivalent to an evaporator) can be used.
Classified by chassis carrying capacity: micro refrigerated trucks, small refrigerated trucks, medium refrigerated trucks, large refrigerated trucks
Classified by carriage type: bread-type refrigerated trucks, van-type refrigerated trucks, semi-trailer refrigerated trucks
important equipment
Refrigerated truck refrigeration unit
Refrigerated truck refrigeration unit: an important equipment that provides a steady stream of "cold" for refrigerated truck containers. It is generally installed on the front and top of the container. It has an air-conditioning-like appearance, but has stronger refrigeration capacity than an air conditioner of the same volume.
Refrigeration units are generally divided into two types, independent units and non-independent units. The difference is that the independent unit completely uses another unit to generate electricity for maintenance, while the non-independent unit completely uses the engine power of the vehicle to drive the unit. Refrigeration work.
Selection of refrigeration units for refrigerated trucks.
Generally, refrigeration units with different power cooling capacities are selected based on the volume of the refrigerated compartment and the temperature requirements of the transported goods.
