With the development of the economy and the improvement of people's living standards, Chongqing refrigerated trucks have brought more convenience to people's lives. In daily life, there is a seemingly insignificant small object that also plays an indispensable role in people's daily lives. That's a refrigerated truck.

（1） Important considerations when choosing a refrigerated truck

1. The selection of the vehicle body based on the goods is related to the specific goods to be transported. Vehicle manufacturers and users propose specific requirements for customization.

2. Convert regular containers to refrigerated containers

Ordinary cargo containers can be replaced with refrigerated containers, but using ordinary cargo containers for refrigerated containers. Because ordinary cargo boxes are made of iron or steel, the insulation effect is not very good, and they are also prone to rusting, such as seafood products.

（2） Refrigerator selection

1. Independent or non independent units

Non independent refrigeration units are inexpensive and easy to maintain. But this type of unit itself does not have a power unit and relies on the car engine to drive the compressor to work; Affected by the working conditions of the car engine, its performance is not as good as that of an independent unit.

A standalone refrigeration unit has its own engine and generator system, providing power and electrical energy for the refrigeration system. It can work independently and is not limited by the working state of the car engine. The performance of this radiator is relatively stable, but the price is high and the accessories are also expensive.

For distance distribution, if the carriage is less than 7 meters, it is recommended to use non independent units. Not only is the procurement cost lower, but even in the event of a malfunction, it is relatively easy to find a repair point.

For long-distance transportation, if the carriage exceeds 7 meters, it is recommended to use an independent refrigerator because even if the car engine stops working during long-distance transportation, the refrigerator can still cool down normally to meet security requirements. Items transported.

2. Low temperature units or preservation units

In terms of price, cryogenic units are more expensive and have lower cooling temperatures. Preservation units are relatively cheap. However, for cheap fresh-keeping units, the unit itself does not have defrosting function, and even some fresh-keeping units claim to be able to reach minus ten degrees Celsius, which is somewhat exaggerated. When selecting, choose a low-temperature unit or a fresh-keeping unit according to the different temperature requirements of transporting goods in a small refrigerated truck.

3. Imported refrigeration machine or domestically produced refrigeration machine

Whether it is a domestic or imported unit, it should be noted that the temperature sensor of the unit can be installed at the return air position of the evaporator, because the temperature sensor of the unit is installed at the return air or exhaust air position, and the temperature readings will differ by about 5 degrees.
