1. Independent vehicles or non-independent units are selected for refrigerated trucks: Non-independent refrigeration units are cheap and easy to maintain. However, such a unit itself does not have a power plant, and it must rely on the automobile engine to drive the compressor; it is affected by the working condition of the refrigerated engine and its performance is not as good as an independent unit. Stand-alone refrigeration units have their own engine and generator units that provide power and electrical energy to the refrigeration system. It can work independently and is not limited by the working state of the engine of a freezer vehicle. This cold machine performance is relatively stable, but the price is higher and accessories are more expensive. Refrigerated truck non-independent refrigeration units: Short-distance distribution within the city or between districts and counties. With cars of around 7 meters or less, non-independent units are recommended. Not only is the procurement cost lower, even if a fault occurs, maintenance is relatively easy. For long-distance transportation, if the carriage is more than 7 meters, it is recommended to use a stand-alone refrigerator, because even if the engine of the refrigerated truck stops working during the long-distance transportation, the refrigerating machine can still be normally cooled to meet the safety of the transported items.
