Foreign refrigerated trucks will use liquefied nitrogen to cool down without a cooler

According to the latest reports from foreign media, the brand new Boreas Nitrogen Cooling Systems has been successfully developed, and after two years of field testing in California, USA, it can now replace the traditional compressor refrigeration system.

At the TMC (Technology and Maintenance Council) annual meeting held in early March, the person in charge of research and development said that the Borias nitrogen refrigeration system adopts a new "dual-zone system", which can form two zones in the cargo box. In areas with different temperatures, the cooling effect is more ideal, the operating cost is lower, and it is more beneficial to environmental protection.

Briefly explain the principle of this set of nitrogen refrigeration, that is, liquid nitrogen is connected to the cargo box through pipelines. Once the liquid nitrogen contacts the relatively warm air in the cargo box, it will immediately become cold to achieve the effect of refrigeration. However, the oxygen content in the closed space will be reduced, so a more complex sensor system will be installed in the cargo box to ensure that the driver or other personnel on the refrigerated truck will not endanger their lives due to lack of oxygen.

Compared with the traditional compressor refrigeration system, this nitrogen refrigeration system has the following advantages:

1. Precise temperature control, better cooling effect

The user can use the Borias nitrogen refrigeration system to set two different temperatures in the same cargo box, change the position of the partition at the same time, and adjust the size of the temperature zone. In addition, the temperature control is more precise, which avoids the disadvantage of inconsistent temperature between the front and back of the cargo box caused by the traditional refrigeration system.

2. High economy and low maintenance cost

Borias nitrogen refrigeration system, after two years of field application in California, has proved that compared with traditional refrigeration systems, this system can greatly save operating costs, save fuel consumption by 20%, and daily maintenance costs by 15%-24 %.

3. Zero carbon emissions, smooth and silent operation

According to the introduction of the research and development personnel, the carbon emission of this refrigeration system is zero when it is working, and it runs quietly without generating noise, which can create a good driving environment for the driver.
