A good car accompanied, happy often accompanied.
Still worrying about the long-distance worry about the breakdown of the goods? Is it still worrying about the perishable things in hot summer? Choose a good car, worry away from life. However, in the face of all kinds of refrigerated trucks, how to make the principle of a cooling efficient, cost-effective refrigerated truck ? Selecting the cooler is the key. Good horse with good saddle, good car with good material. The attitude determines fate, and the refrigeration system determines the lane.
Different cooling methods, different transportation uses. To choose a good car, you must first understand the refrigeration system of the refrigerated truck . Refrigerated trucks often use five cooling methods, each with its own advantages and disadvantages.
Water ice or salt ice refrigeration system. Its production cost is low, the raw materials are easy to process and obtain, which reduces the cost of later use. However, the durability of cooling is not strong, and the insulation effect is not ideal. Salt ice can easily dissolve and erode the cabin, making the cargo wet, making it more suitable for the transportation of seafood.
Dry ice refrigeration system. Dry ice is a commonly used physical cooling substance, which occupies a small space, which can reduce the burden on the vehicle body and reduce fuel consumption. Dry ice cooling slows down and prevents oxidation reactions, preventing items from deteriorating. However, the use cost of dry ice is high and it is not easy to preserve, and the consumption is large. As a result, the temperature inside the box is not easy to adjust and the applicable range is relatively small. The dry ice is used for the transportation of small and medium-sized fruits and vegetables.
Liquid nitrogen refrigeration system. The chemical refrigeration method is a relatively advanced refrigeration technology. It has the advantages of low noise and pollution, small space occupation, large cooling capacity, good effect, and high speed. Nitrogen refrigeration makes the items less susceptible to moisture and allows precise temperature control. Nitrogen has a high cost of use and limited promotion. It is used for the transportation of high-density products such as medical supplies.
Mechanical refrigeration system. The continuous innovation in the more traditional refrigeration methods has the characteristics of high safety, long-lasting cooling effect, low cost of use and convenient maintenance in the later period. Physical refrigeration is recyclable, environmentally friendly and clean, and supported by a low-carbon life. However, the space occupied by the refrigeration system is large, and the weight of the vehicle body is increased. Mechanical friction causes greater fuel consumption and tire damage, which increases maintenance costs. The way of mechanical refrigeration makes this kind of refrigerated truck use longer. It is loved by many customers. The use of new materials is also reducing their inherent deficiencies and will become an important development direction for the future refrigeration refrigeration system.
Cold plate cooling system. Small pollution, environmental protection and clean, easy to use. However, the cold plate body is heavy and bulky, resulting in a short duration of use. It is suitable for medium and short distance transportation. With the improvement of low-carbon environmental protection requirements, with the continuous improvement of new materials, it will also occupy a place.
Do not choose the best, just choose the most suitable. Choosing a good car to refrigerate is a good fit for life.
