How to Ventilate a Refrigerated Truck?
2 Answers
Refrigerated trucks should keep the refrigeration unit running when ventilating. Here are the relevant details: 1. Independent Refrigeration Unit: Independent and non-independent refrigeration units are categorized based on their power source. An independent refrigeration unit has its own dedicated power source, meaning the unit itself is equipped with an independent power supply. Generally, independent refrigeration units are of an integrated structure, though there are also modified split-type structures (usually mounted on the vehicle's frame). These units come with an engine and generator that provide power and electricity to the refrigeration system. They can operate independently without being affected by the working state of the vehicle's engine. 2. Non-independent Refrigeration Unit: This type of refrigeration unit cannot operate independently for refrigeration. It lacks its own power source and must rely on the vehicle's engine to drive the compressor.
When I first started refrigerated truck transportation, I often overlooked the importance of ventilation, only to realize later that it was crucial for preserving the entire cargo. Ventilation refers to briefly opening the rear compartment door after parking to release internal humid and hot air. The steps are simple: find a safe spot to park and ensure the brakes are secure, then use the key or switch to open the door for about 5 minutes (don’t exceed this time), while also checking for any dampness or unusual odors in the cargo. Before closing the door, take a quick look to ensure no debris is blocking the seal, then shut it tightly and restart the refrigeration. This prevents moisture from condensing into water droplets, avoids mold on vegetables and fruits or spoilage of seafood, and also makes the refrigeration system more efficient and energy-saving. After developing the habit of ventilating every 2-3 hours of transport, my cargo loss rate dropped significantly, and I no longer worry about customer complaints regarding freshness issues.
