Description

Technical Field

[0002] The refrigeration unit of a refrigerated truck is an important equipment that provides a steady supply of refrigerated truck containers. It is generally installed on the front top of the container. It has an air-conditioning-like appearance, but has a stronger cooling capacity than air conditioners of the same size. Refrigeration units are generally divided into two types, independent units and non-independent units. The difference is that independent units are completely powered by another unit to maintain their work, while non-independent units are completely powered by the engine of the entire vehicle to drive the refrigeration work of the unit. The advantage of independent refrigeration units is that they are stable and reliable, which is also what refrigerated trucks need. Since independent refrigeration units have a separate power output source, the refrigerator can still work when the refrigerated truck is turned off or the engine fails in the refrigerated truck, thereby ensuring that the goods in the refrigerated compartment will not deteriorate. The disadvantage of independent refrigeration units is that they are expensive and their maintenance is relatively complicated compared to non-independent refrigeration units. Due to the addition of a power system, independent refrigeration units are more complicated than non-independent refrigeration units in terms of maintenance, and independent refrigeration units are relatively complex in technology and have high prices.
