II. How refrigerated containers work

Refrigeration shipping containers play a vital role in modern logistics and transportation, ensuring that a variety of perishable goods remain fresh and safe during transportation. Understanding how they work is key to understanding their functions and applications. Below, we’ll take a closer look at their operation:

• Refrigeration system: The core of a refrigerated container is the refrigeration system, which controls the temperature inside the container by circulating refrigerant. Refrigeration systems typically include components such as compressors, condensers, evaporators, and expansion valves.
• Temperature control: The refrigeration system controls the temperature inside the container by regulating the operation of the compressor and the heat dissipation of the condenser. Temperature sensors monitor the temperature inside the container and feed the data back to the control system to ensure the temperature remains within the required range.
• Air circulation: They are also equipped with an air circulation system that evenly distributes cold air into the interior of the container through fans to ensure even cooling of the cargo. This helps prevent hot spots, thereby maintaining the quality and freshness of your goods.
• Humidity Control: Some premium refrigeration shipping containers are also equipped with a humidity control system that regulates the humidity levels inside the container. This is particularly important for certain commodities, such as vegetables and fruits, as maintaining proper humidity helps extend the shelf life of goods.
• Security Features: Refrigerated containers often have security features such as door locks and temperature alarm systems. These features ensure the safety and integrity of goods during transportation.
• Energy supply: It is typically provide power using a built-in generator set or connected to an external power source. These generator sets are usually powered by diesel engines and can provide stable power without an external power source.
• Application fields: They are widely used for the transportation of perishable goods such as food, medicines, and chemicals, as well as the transportation of special commodities such as flowers and seafood.

Refrigeration shipping containers ensure that goods maintain ideal temperature and humidity conditions during transportation through complex and effective refrigeration systems and air circulation systems. An in-depth understanding of how refrigeration shipping containers work can help us make better use of this critical transportation tool to ensure the quality and safety of goods.

III. Types of refrigerated containers

Refrigeration shipping containers can be divided into several different types based on their functionality and design features. Here are some common refrigeration shipping container types:

• Standard refrigeration shipping container: This container is the most common type and is typically used to transport food, pharmaceuticals, and other temperature-sensitive goods. They are equipped with refrigeration systems to keep goods fresh within a specific temperature range.
• Cryogenic containers: Cryogenic containers can maintain extremely low temperatures and are often used to transport frozen food and other goods that require extremely low temperatures.
• Heated refrigeration shipping container: This type of container has a heating function to prevent cargo from freezing in cold environments, and is usually used to transport liquid cargo that is easy to freeze.
• Multi-temperature zone refrigerated container: This container has multiple independent temperature zones and can transport a variety of goods with different temperature requirements at the same time, improving transportation flexibility and efficiency.
• Fresh air ventilated container: This type of container has a ventilation system that can provide fresh air to help maintain the freshness of the cargo, and is suitable for some cargoes that require higher ventilation.
• Refrigerated tank truck container: This type of container combines the functions of a truck and a refrigeration shipping container. It can transport goods directly on land and is suitable for short- and medium-distance freight.

While these different types of refrigeration shipping containers meet different cargo transportation needs, they also reflect the trend of continuous innovation and development in the cold chain logistics industry.
