The technology behind reefer containers is a fascinating blend of engineering and innovation, designed to maintain precise temperature control throughout the shipping process. At the heart of a reefer container is the refrigeration unit, which operates on the principles of the vapor compression cycle. This cycle involves the circulation of refrigerant through a closed system, where it undergoes phase changes that absorb and release heat, thereby cooling the interior of the container.
The refrigeration process begins with the compressor, which pressurizes the refrigerant, causing it to become hot and gaseous. The hot gas then flows through the condenser coils, where it releases heat to the surrounding environment and condenses into a high-pressure liquid. This liquid refrigerant then passes through an expansion valve, which reduces its pressure and temperature, turning it into a cold, low-pressure gas. The cold gas then flows through the evaporator coils inside the container, absorbing heat from the cargo space and cooling the interior. This cycle repeats continuously, maintaining the desired temperature within the container.
In addition to the refrigeration unit, reefer containers are equipped with advanced control systems that monitor and regulate temperature, humidity, and airflow. These systems often include sensors and data loggers that provide real-time information on the container’s internal conditions.
