Recently, many customers who purchase refrigerated trucks have come up with a question. Is the independent unit of refrigerated trucks good or not independent? How to choose? A few days later, Xiao Bian gave you the difference between the two for reference.
1. What are independent refrigeration units and non-independent refrigeration units?
Independent chiller units: Independent and non-independent chillers are based on power sources. Independent chillers means that chillers have separate power sources. In other words, the chillers themselves have independent power sources. Most of the independent refrigeration units are one-piece structures. It can work independently and is not limited by the working status of the engine.
Non-independent refrigeration unit: It is a refrigeration unit that cannot work independently. This unit has no power unit and must rely on the engine to drive the compressor.
2. The advantages and disadvantages of independent refrigeration units and non-independent refrigeration units
Independent refrigeration unit
Advantages: The advantage of an independent refrigeration unit is its stability and reliability, which is also the key to a refrigerated truck. Because the independent chiller unit has a separate power output source, the chiller can continue to work when the refrigerated vehicle stalls or when an engine failure occurs in the refrigerated vehicle, thereby ensuring the temperature inside the refrigerated vehicle compartment.
Disadvantages: The disadvantage of independent refrigeration units is that they are expensive. Due to the addition of a power system, maintenance will be more complicated and the price will be higher than it is.
Non-independent refrigeration unit
Advantages: The advantage of a non-independent refrigeration unit is that the price is cheaper, the structure is simple, and it is easy to maintain and maintain.
Disadvantages: The disadvantage of the non-independent refrigeration unit is that it relies too much on the power source of the refrigerator car. When the refrigerator car engine stops working, the non-freezing refrigeration unit will lose its power support and the refrigeration system will stop working if the refrigerator stalls. Frequent opening of the car door will cause a large amount of cold air to leak out of the box, causing the temperature in the car to rise. Or in the event of a fault in the refrigerated truck, the refrigerator will stop cooling and the cargo in the compartment will be vulnerable to loss.
3, the choice of independent refrigeration units and non-independent refrigeration units
From the price point of view: the price difference between the non-independent chiller unit and the independent chiller unit is more than tens of thousands of yuan, the budget is relatively abundant, and the temperature requirement in the vehicle compartment is not very high (the required temperature is at least minus 10 degrees below). It is better to use a freestanding proposal.
From the length of the transport distance: In the short-distance distribution within the city or between districts and counties, the use of non-independent units is recommended. Not only the procurement cost is lower, but even if a failure occurs, the maintenance is easy; for long-distance transportation, it is recommended to use a stand-alone refrigeration unit because Even if the car engine stops working during long-distance transportation, the chiller can still be normally cooled to ensure the safety of the transported items.
From the model to be used: In general, light trucks with a body size of less than 7 meters are recommended. Non-independent units are recommended. Trucks with a 7-meter-plus truck or semi-trailer are better equipped with free-standing units.
In short, in the purchase of a comprehensive selection of various aspects, the two refrigeration units have their own advantages and disadvantages, only the best for their own transport environment.
