In the transport stage of cold chain logistics, the condition of the reefer container directly affects cargo quality, and certain common problems can lead to temperature loss of control or cargo damage. Many practitioners tend to overlook detailed management in actual operations, increasing transport risk. The core of these problems involves the container structure, temperature-control system, and operating procedures, and their probability of occurrence can be substantially reduced through systematic preventive measures.

Temperature fluctuation is a common problem during reefer container transport, mainly triggered by changes in the external environment or power interruption. If the container's insulation layer has aged or is damaged, it accelerates heat exchange, causing the internal temperature to deviate from the set range. Preventing this problem requires regular inspection of the container's sealing to ensure the insulation material remains intact. Simulated environmental testing before transport can also help identify potential weak points and repair vulnerabilities in advance. The temperature-control system of the reefer container should be equipped with a backup power source or alarm device that switches over automatically when power supply is unstable, maintaining a stable environment.

Condensation accumulation is another common problem, mostly caused by improper internal humidity control or an excessive external temperature differential. After water vapor condenses on the container walls, it may drip onto the cargo, affecting packaging integrity or triggering mold. Preventive measures include optimizing the container's ventilation design to ensure cold air circulates evenly and to avoid localized high-humidity zones. Routine cleaning of the reefer container should cover the drainage channels to prevent blockage. Monitoring humidity-sensor data during transport and adjusting parameters promptly reduces the risk of water-vapor buildup.

Equipment failures such as compressor malfunction or sensor error will interrupt the normal operation of the reefer container, causing transport delays. These problems often stem from insufficient maintenance or component aging. The prevention strategy emphasizes regular professional servicing, including inspecting compressor condition, calibrating sensor accuracy, and replacing wear parts. Operator training is likewise essential, ensuring correct startup and monitoring of the system. The remote-monitoring technology of the reefer container can feed back operating data in real time, helping to respond quickly to anomalies and limit the spread of faults.

Container structural stress induced by improper cargo loading is a potential in-transit problem that may damage the container door hinges or internal bracing. Preventive methods include standardizing the loading process to avoid overly dense or overweight cargo stacking. Using suitable securing devices disperses pressure and protects container integrity. Assessing the degree of route jolting before transport and selecting a reinforced reefer container can enhance impact resistance.
