The choice of small refrigerators mainly depends on the three main parts of the car chassis, insulation carriages and refrigeration units. Only these three parts are of reliable quality to ensure the reliability and stability of the mini-refrigerators in the refrigerated transport process. Chassis selection 1, truck chassis or tractor form There is actually no rigid requirement for the choice of truck chassis or tractor chassis. It is mainly determined by the amount of cargo transported by the vehicle owner and the transport distance. In general, the choice of a light truck chassis at a closer distance, a longer distance and a large volume of transport Optional traction semi-trailer form. 2, imported chassis or domestic car chassis The advantages of imported chassis are low maintenance, good maneuverability and fuel economy. The disadvantage is that the price is too high. The biggest advantage of domestic car chassis is that it is cheap, but there are more minor problems. 3, buy their own or commissioned car manufacturer to buy In fact, it is the same for the buyers who want to buy their own car. Many buyers think that the car manufacturer will buy the car, and the manufacturers will make money in the middle. In fact, the car manufacturers often buy modified car chassis and generally have a good relationship with manufacturers. The chassis they receive is cheaper and more suitable for retrofit production. And the body and chassis are purchased in one factory, and the buyer can lower the price better. As long as the attention to the parameters of the chassis at the time of signing the contract, etc., in the car manufacturers to buy more convenient. The choice of car body 1, according to the cargo fixed body The choice of the car body is related to the delivery of the specific goods. The manufacturer of the car body manufacturer makes specific demands to customize. 2, Ordinary container change refrigerator? Many netizens asked whether ordinary containers can be changed into refrigerators. The manufacturer's answer is yes, but it is not recommended to use ordinary containers to change refrigerators. They think that it is more cost-effective to convert directly into a refrigerated compartment because the general cargo compartment is made of iron or steel and the heat insulation effect is not very good. At the same time, it is also prone to rust. For example, the seafood is pulled, and the seawater is corrosive. In the selection, it is necessary to pay attention to the anti-corrosion of the car body material. Refrigeration unit selection 1. Independent or non-independent unit Non-independent refrigeration units are cheap and easy to maintain. However, such a unit itself does not have a power plant, and it must rely on the automobile engine to drive the compressor; it is affected by the working conditions of the automobile engine and the performance is not as good as an independent unit. Stand-alone refrigeration units have their own engine and generator units that provide power and electrical energy to the refrigeration system. Can work independently, not limited by the working status of the car engine. This cold machine performance is relatively stable, but the price is higher and accessories are more expensive. For short-distance distribution within the city or between counties and districts, if the carriage is less than 7 meters, it is recommended to use non-independent units. Not only is the procurement cost lower, even if a failure occurs, it is relatively convenient to find a maintenance point. For long-distance transportation, where the carriage is more than 7 meters, it is recommended to use a stand-alone refrigerator, because even if the car engine stops working during long-distance transportation, the refrigerator can still be normally cooled to meet the safety of the transported items. 2, cryogenic or fresh-keeping units In terms of price, the chilled units are expensive and the cooling temperature is lower. Fresh-keeping units are relatively cheap. However, for a low-cost fresh-keeping unit, the unit itself does not have a defrosting function. Even if some fresh-keeping units claim to be able to achieve a minus ten degrees, it is an exaggeration. At the time of purchase, choose the cryogenic unit or the fresh-keeping unit according to the different temperature requirements of the small-size refrigerator car. 3, imported refrigeration unit or domestic refrigeration unit Regardless of the domestic or imported units, it must be noted that the unit's temperature sensor is enough to be installed in the return air position of the evaporator. Because the unit's temperature sensor is installed in the return air or exhaust position, the temperature reading will differ by about 5 degrees. . Finally, we must remind everyone that due to the large investment in small refrigerators, when there is no fixed supply, do not blindly enter the small refrigerator car industry, so as to avoid unnecessary losses, there are many small refrigerated trucks can not match the goods when the general truck of.
