Can a refrigerated truck still refrigerate after stalling?
2 Answers
Generally, after a vehicle stalls, the onboard refrigerator cannot cool due to lack of power. Here are the relevant introductions: The role of refrigerated trucks: The emergence of refrigerated trucks has enabled many perishable foods such as fruits, meats, and cold drinks to be transported over long distances under frozen and fresh-keeping conditions. Classification of refrigerated trucks: Refrigerated trucks are divided into two main categories: refrigerated automobiles and railway refrigerated trucks. Refrigerated automobiles are mainly used for the internal transportation of food within cities, such as transporting cold drinks, fresh fruits, fish, and meat from factories to various stores, and sometimes also for medium and short-distance intercity refrigerated transportation. Railway refrigerated trucks undertake the task of medium and long-distance refrigerated food transportation.
A refrigerated truck can stay cold for a while after the engine is turned off, but don't rely on it too much. Most refrigerated trucks have an independent cooling system powered by a backup battery, which can keep running for a few hours after the engine is off, maintaining the temperature fairly well. The issue is that the battery has limited capacity—if it's old or the weather is hot, efficiency drops quickly, and it won't hold the low temperature for long. I recommend making it a habit to check if the refrigeration unit is properly lit before shutting off the engine and regularly testing the battery condition to avoid breakdowns. Drivers transporting perishable goods need to be extra careful—temperature fluctuations can spoil the cargo, leading to significant losses. In short, short stops are manageable, but for long stops, you’ll need to find a charging point or start the engine immediately to recharge.
