Cold King agents usually choose independent refrigeration units or non independent refrigeration units based on the size of the refrigerated compartment.
From the market perspective, refrigerated trucks with a cargo volume of 4-31 cubic meters and a body length of less than 6 meters should choose non independent units.

Refrigerated trucks with a body height of more than 6 meters should choose independent refrigeration units. Depending on the vehicle, for example, independent refrigeration units are used for cargo trucks and trailers, and medium-sized independent refrigeration units are often used for cargo trucks; Semi trailers often use large refrigeration units, which are commonly arranged in front of the trailer.
1. A refrigeration unit is used to maintain the temperature of goods, not to lower the temperature of goods. Many users of refrigerated trucks have a misconception that the refrigeration unit on small refrigerated trucks can freely freeze or heat the goods loaded into the compartment to the desired temperature.
2. Because the refrigeration unit of the refrigerated truck does not lower the temperature of the goods, but maintains the temperature of the goods, it is like the cotton quilt we used to wrap the goods when selling cold drinks in the past. When the external cold (heat) source radiates, conducts, and convection into the compartment, it is carried away by the cold air blown out by the refrigeration unit, isolating the heat source from entering the goods.
3. When loading a small refrigerated truck, the compartment should be pre cooled or preheated first. When loading (like unloading), the refrigeration unit should be turned off.
