How to choose a refrigerator car
First, the choice of refrigerated truck chassis:
The chassis of the car is relatively easy to select. Because we can only select the automobile chassis that meets the national standards for environmental protection in China, regardless of the size of the tonnage, domestic or imported car chassis are the same requirements. For the car chassis, whether the customer purchases the private car Body manufacturers buy the same.
Second, the choice of refrigerator body:
The choice of the car body is related to the delivery of the specific goods. Different goods have different requirements for the car body. For example, refrigerated trucks that carry fresh meat need to be custom-made hooks on the car body; refrigerated trucks that distribute fresh food for the stores have small batches, many varieties, and require multi-temperature refrigerated trucks; the temperature needs are different, and frequent loading and unloading require more refrigerated trucks. All of these, the user can customize the car body according to specific needs.
Third, the choice of refrigeration vehicle refrigeration unit:
(1) Choose according to the size of the refrigerated compartment: Independent units or non-independent units can be selected. In general, a car with a height of 6 m or more is suitable for selecting independent units. The size of an independent unit can be determined according to the length of the car. Non-independent units shall be used for the carriages below 6 meters, where the room temperature is to reach -20 °C.
(2) According to the temperature requirements of the goods shipped by the refrigerated truck: The cryogenic unit or the fresh-keeping unit can be selected. In terms of price, it is more expensive and fresher units are relatively cheap. For an inexpensive fresh-keeping unit, the unit itself does not have a defrosting function, and even if some fresh-keeping units claim to be below minus ten degrees, it is an exaggeration.
(3) Choose according to the requirements of distribution of refrigerated trucks: For example, when refrigerated trucks are used to distribute ice-creams from point to point in the cities, then it is necessary to choose regenerative cooling units or independent units. Only long-distance or point-by-point distributions with long distances in the city are required. Only suitable for fan-type refrigeration units.
(4) According to the origin and brand of the refrigerator: You can use imported or domestic brands.
There is also to tell everyone that regardless of domestic or imported units, we must pay attention to the unit's temperature sensor is enough to install in the return air position of the evaporator, because the unit's temperature sensor installed in the return air or exhaust position in two cases, The temperature reading will differ by 5°C.
