Chengli refrigerated truck tells you which independent and non-independent refrigeration unit is more suitable for you
The quality of a refrigerated truck is determined by the three parts of the chassis, the car body and the refrigeration unit. Among them, the choice of refrigeration units is the top priority. Netizens who have some knowledge of refrigerated vehicles should have heard of independent refrigeration units and non-independent refrigeration units. How are these two types of refrigeration units distinguished? To this end, Xiaobian found information on the Internet, consulted the staff of refrigerated truck manufacturers, and compiled the following to facilitate everyone's learning.
● What are independent refrigeration units and non-independent refrigeration units
Independent refrigeration unit: Independent and non-independent refrigeration units are divided according to the source of power. Independent refrigeration unit means that the refrigeration unit has a separate power source.
Generally speaking, independent refrigeration units are integrated, but there are also modified split structures (this structure is generally hoisted on the beam of the car). This unit itself has an engine and generator that provide power and electrical energy to the refrigeration system. Device. Able to work independently without being restricted by the working state of the car engine.
Non-independent refrigeration unit: As its name implies, it is a refrigeration unit that cannot work independently. Such a unit has no power unit and must be driven by a car engine to operate the compressor.
The non-independent refrigeration unit can also be divided into an integrated structure and a split structure. The split structure includes three types of condenser front type, condenser top type and condenser bottom type (bottom or concealed type); but the condenser front type structure is the most common structure in the split non-independent refrigeration unit. form.
● Advantages and disadvantages of independent refrigeration units and non-independent refrigeration units
Independent refrigeration unit
Advantages: The advantages of independent refrigeration units are stability and reliability, which is also the most needed for refrigerated trucks. Since the independent refrigeration unit has a separate source of power output, the refrigerator can still work when the refrigerated truck goes out or the engine of the refrigerated truck fails, thereby ensuring that the goods in the refrigerated compartment will not deteriorate.
Disadvantages: The disadvantage of independent refrigeration units is that they are expensive and maintenance is more complicated than non-independent refrigeration units. Due to the addition of a set of power systems, the independent refrigeration unit is more complicated than the non-independent refrigeration unit in maintenance, and the independent refrigeration unit is relatively more technically complex and the price is higher.
Non-independent refrigeration unit
Advantages: The advantages of non-independent refrigeration units are cheap, simple structure and easy to maintain and maintain.
Disadvantages: The disadvantage of the non-independent refrigeration unit is that it is too dependent on the power source of the refrigerated truck. When the engine of the refrigerated truck stops working, the non-independent refrigeration unit loses its power support and the refrigeration system stops working. The large amount of cold air in the car box causes the temperature in the car to rise, or when the car fails (engine failure), the refrigerator will also stop cooling, and the goods in the car are vulnerable to loss.
● Selection of independent refrigeration unit and non-independent refrigeration unit
In terms of price: if the price difference between the non-stand-alone refrigeration unit and the stand-alone refrigeration unit is more than tens of thousands of yuan, the budget is more abundant, and the temperature in the compartment is not very high (the required temperature must be at least -10 degrees below zero) It is better to use the freestanding style.
From the length of the transportation distance: non-independent units are recommended for short-distance distribution in the city or between districts and counties. Not only the purchase cost is lower, but also maintenance is easy even if there is a failure. It is recommended to use independent refrigeration units for long-distance transportation. Even if the car engine stops working during long-distance transportation, the refrigerator can still cool normally to ensure the safety of the transported items.
In terms of models: Generally speaking, for light trucks with a car body below 7 meters, it is recommended to use a non-independent unit. It is better to use a free-standing car for 7 meters to load trucks and semi-trailers.
There is a saying that is very good, there is no best, only the best for you. Independent refrigeration units have obvious advantages in stability and reliability, but their prices are high. Non-independent refrigeration units are cheaper and easier to maintain. Each has its own advantages and disadvantages. When purchasing, you must comprehensively choose from two aspects. Two types of refrigeration units No one is better than anyone, and only the one that suits their transportation environment is the best.
