The delivery of frozen goods is a very important component of modern trade. For this purpose, a refrigerated truck is used - a car equipped with a special heat-insulating trailer with a refrigeration unit. Next, let's talk about the functionality and some of the technological features of this vehicle.
Refrigerated functionality
The main function of a refrigerated truck is to maintain a certain temperature regime for transporting frozen or perishable products:
meat;
fish;
dairy products.
What technologies are used?
The transport refrigerator works by installing isometric vans with refrigerated compartments. These vans are made of frameless sandwich panels, and in some cases, foam plastic and other high-quality and efficient heat-insulating materials are actively used. In addition, a refrigeration or eutectic unit is installed in the conveyor. It is this component that allows you to maintain a given temperature regime throughout the entire transportation route.
The refrigeration unit works on the principle of a looped circuit, through which a refrigerant is continuously circulating - a gaseous or liquid substance, the physical properties of which are characterized by heat absorption due to isometric expansion and the release of cold condensate.
How did this technique come about?
Initially, the vans were equipped with huge chunks of ice, which were pressed into briquettes or packaged in strong bags, due to which the melting process was slowed down to the required state. Subsequently, the development of this industry led to a significant modernization of transport, and the production line was redesigned to new standards.
