At present, the cold chain industry is very hot, and its derivative product is a refrigerated truck. To judge whether it is a good quality refrigerated truck, the first prerequisite to see is the refrigeration unit. How to choose a refrigerating vehicle refrigeration unit is the key to the key. Next we will introduce the relevant knowledge of the refrigerating vehicle refrigeration unit .
The refrigerating truck refrigeration unit is composed of components such as a condenser, a compressor, an expansion valve, an evaporator, and a control system. First, it can be divided into independent and non-independent units according to the power source. The former's power output depends on a separate diesel engine. The latter is based on the chassis of the car. In the case of refrigerated trucks with a length of 7 meters or more for long-distance transport, independent refrigerating units may be used; for refrigerated trucks with a length of 3–6 meters in short-distance transport, it is recommended to use non-freezing refrigerating units. Second, it can be classified according to temperature as fresh-keeping (carriage temperature is kept at around 5 degrees) and low-temperature freezing (carriage temperature is kept below minus 15 degrees). If you are transporting fruit, vaccines, or vegetables, refrigerated trucks of fresh-keeping refrigeration units will be selected. If it is ice cream or frozen products, choose the latter. Third, it can be divided into imported and domestic refrigeration units according to the place of production. Imported chillers generally include the United States Da Leng Wang, the United States Carrier, South Korea and China. Domestic refrigeration units are generally commonly used in Guangdong K brand, Yingda green cold, and Beijing ice source.
There are many types of machine cooling, such as absorption, vapor compression, steam injection, and air insulation expansion. At present, most refrigeration trucks use vapor compression mechanical refrigeration.
Refrigerated trucks have great economic significance for ensuring the fresh quality of goods. With the continued growth of China's economy, there is a huge potential for the development of the refrigerated truck market, among which refrigeration units are critical to the overall performance of refrigerated trucks. Therefore, the seller needs to select the proper refrigeration unit according to his own model and capital situation. Only by choosing the right refrigeration equipment and cabinet, the quality of the goods can be guaranteed. Do not try to be cheap and lose money.
