Characteristics of refrigerated containers
- Temperature range from -40°C to +30°C, depending on the model and settings;
- The precise microclimate of the container’s internal environment is regulated by built-in cooling systems;
- The energy efficiency of refrigerated containers is ensured by the economy in energy consumption compared to other types of cooling equipment;
- The mobility of refrigerated containers is ensured by their easy movement to different sites;
- External control and monitoring of container operating modes simplifies management and monitoring.
Construction of refrigerated containers
The outer structure of refrigerated containers consists of a frame made of aluminium sheets, which provides the necessary strength. The inside of the container is a refrigerated chamber lined with a layer of heat-insulating polymer, which is often polyurethane foam or polyvinyl chloride foam panels.
The walls, floor and ceiling of the container interior are made of plywood sheets coated with an anti-corrosion coating. The floor is made of an aluminium profile, which provides strength to withstand the weight of the warehouse load.
Doors with an aluminium frame and an inner layer of polymer of the same thickness as the walls are used for loading. The door is equipped with a special lock that ensures the tightness of storage in the compartment.
During loading, containers are placed on special pallets at a certain distance from each other. Certain dimensional schemes are used for the correct placement of containers. Signal tags are used to control the loading process.
To maintain the required conditions inside the container, refrigeration equipment is used: a refrigerator compressor and sensors. This compressor operates automatically in a programmable mode, providing a temperature range from -40°C to +30°C.
A specialized electronic control unit and sensors monitor the conditions inside the container and record any problems. They also provide automated storage, minimizing the risk of product spoilage.
The airflow in the container is supplied through the floor and rises up the walls to the ceiling. It is then returned to the cooling unit to lower or raise the temperature according to the set program.
