Among the three major components of refrigerated trucks, the refrigeration unit is an important link. Due to the small cargo space, there is a higher skill requirement for temperature control.

Refrigerated truck refrigeration unit: an important equipment designed to provide a continuous supply of cold for cold chain truck containers. It is usually installed at the top of the front of the container and has the same appearance as a household air conditioner, but has stronger cooling capabilities than air conditioners of the same volume.

The refrigeration unit of a refrigerated truck generally consists of an evaporator, a condenser, a controller box, a compressor, and high and low pressure rubber hoses. Refrigeration units are generally divided into two types, independent units and non independent units. The difference is that independent units generate electricity through another unit to maintain operation, while non independent units drive the refrigeration operation of the unit through the operation of the vehicle's engine.

The independent unit has its own power source, and the diesel engine that is independent of the unit itself serves as its power source; The power output of non independent units is driven by the engine of the car chassis.

Selection of refrigeration units: Generally, different power refrigeration units are selected based on the volume of the refrigerated container and the temperature requirements of the transported goods.

It is said that goods are not cheap, and the price of imported refrigerators is also very expensive. For example, a set of imported refrigerators for large refrigerated trucks requires tens of thousands of dollars in demand; The semi-trailer model is also cheap and costs 100000 yuan.

In contrast, domestic brands have a significant price advantage, and for users who value price, domestic brands are also a good choice. In terms of cost, the price difference between non independent refrigeration units and independent refrigeration units is over tens of thousands. If the budget is relatively surplus and the temperature requirements for the cabin are relatively low, it is recommended to use imported independent refrigeration units.

Nowadays, refrigerated trucks are commonly used for transporting goods in large and medium-sized cities. However, its industry penetration rate is very low, and every year there are still a large number of food, meat, fruits, vegetables, medicines, alcoholic beverages, etc. that suffer unnecessary losses due to spoilage during transportation.

This further illustrates that there is a huge market for the development of refrigerated warehouses, and the cold storage industry still has a wide range of avenues to explore in this field. Now the government is also supporting and encouraging the use of refrigerated trucks to transport vegetables and fruits, and the exemption of tolls on high-speed green channels is a good condition.
