Proper temperature control of the refrigeration unit is necessary to ensure that Chongqing refrigerated trucks do not make mistakes during long-distance transportation, and the temperature control is uniform, mainly to save transportation costs.

1. Temperature setting of refrigerated truck refrigeration unit

For cold drinks such as ice cream, the temperature setting should generally be between -5 ° C and -15 ° C. Therefore, you need to pre cool the refrigerated truck compartment first, which usually takes one and a half hours.

This step is very important because after the carriage is exposed to sunlight outside, the temperature inside the carriage is relatively high. If it is not pre cooled, it is likely to cause the ice cream to melt and deform, and the carriage temperature may not reach the desired temperature.

2. Pre cooling and insulation of refrigerated truck refrigeration unit

The goods to be transported should be pre cooled to the required temperature in advance, for example, ice cream needs to be frozen, and the carriage should be cooled to around -10. The temperature of the goods should also be checked when loading.

Only when the temperature matches can the goods be loaded, because the refrigeration unit of the refrigerated truck only serves as insulation and cannot lower the temperature of the goods themselves. This is why it is necessary to pre cool the carriage and goods in advance.

Many people mistakenly believe that the refrigeration unit of a refrigerated truck is used to freeze goods. Without pre cooling, the goods are loaded into the compartment, which not only fails to lower them, but also damages or deteriorates them.

When the refrigeration unit of a refrigerated truck is transported for 100 hours, it needs to be maintained and repaired. The main components include the compressor rotating belt, electrical control parts, etc. If there are any abnormalities, they should be repaired in a timely manner.
