Refrigerator unit selection method

The main purpose of a refrigerated truck is to transport closed transport vehicles that require preservation or refrigerated cargo, and is a refrigerating device equipped with a refrigerating unit and a refrigerated transport vehicle made of a polyurethane heat-insulated box. In order for a refrigerated truck to function properly for refrigeration and heat preservation, the crew must control the entire transportation process. There are two types of refrigeration equipment for refrigerated trucks :

1. Free-standing refrigeration units can be selected, which means that the refrigeration unit has a separate power source, that is, the unit itself has a separate power source. Has a one-piece structure, but also has a modified split structure, but this structure is generally only used to lift the car's girder. This type of unit itself is equipped with electric motors and generators that provide power and power to the refrigeration system. It can be operated independently without being affected by the operating state of the vehicle's engine.

2, can choose non-independent refrigeration unit, literally point of view, that is, this type of refrigeration unit is a refrigeration unit without independent cooling operation, and this unit itself is no power device, Must rely on the engine of the vehicle to drive the compressor to operate.

Then know the difference between the refrigeration equipment of refrigerated trucks , how to choose which type of refrigeration unit?

a. It can be selected according to the size of the refrigerated truck's own vehicle. It is also possible to select non-independent units and independent units. However, under normal circumstances, the car above 6M is still relatively suitable for the selection of independent units. It can be decided according to the length of the refrigerated car body to select the size of the independent unit. In the refrigerating compartment below 6M, it is more appropriate to use non-independent units. The temperature in this compartment can reach minus 20 degrees Celsius.

b. The selection can be made according to the required temperature of the articles transported by the refrigerated truck, and the preservative group and the cryogenic unit can be selected. However, from the price point of comparison, fresh-keeping units are relatively cheap, and cryogenic units are more expensive. If the fresh-keeping unit is selected, then the unit can be equipped with a defrosting function. Even if some companies exaggerate their words, their family's fresh-keeping agent group can reach minus ten degrees.

c, can be selected depending on refrigerated trucks to the distribution requirements, if refrigerated trucks knowledge used in various distribution points in cities to the distribution of cold drinks, then it must be to select the independent unit cold storage type or a refrigeration unit, and if you want to For a relatively long distance indoors or long-distance distribution, it is appropriate to use a fan-type refrigeration unit.

d. The choice can be made according to the brand and origin of the refrigerant. Foreign brands can be used. Domestic brands can also be used. However, when we are making purchases, we don't necessarily have the highest price, but we can fit ourselves. Ultimately, you need to make a comprehensive selection based on your transportation environment and the items you deliver.
