In refrigerated transportation, goods should be stacked on double boards to avoid blocking the air circulation in the goods. Circulating air conditioning, a method for improving the quality of refrigerated transportation products introduced in Chongqing refrigerated truck transportation, is commonly used for ventilation of aluminum iron floors, and the use of flat anti slip floors also has this effect.

1、 Ensure the circulation of cold air

Due to the defrosting design of refrigeration units used for refrigerated transportation, air can thaw quickly. When goods and outlets are too close to the unit in the evaporator coil, rapid frosting (or freezing) can affect the goods, and the air sensing switch can thaw quickly.

When the temperature of the coil returns to the standard temperature, defrosting immediately ends, so there will be an operating cycle that will cause a decrease in the temperature of the loading body. Everyone's intuition is that they always need to frequently replace the defrosting device, but this is not the case. This will only increase the cost of refrigerated transportation. Be careful when loading and unloading to ensure the circulation of cold air on the surface.

2、 Keep the carriage clean

The interior of refrigerated transportation should be kept clean and free of packaging paper and shredded paper to prevent debris from obstructing air circulation. When using a refrigerated truck, it should be kept clean. Due to the action of the evaporator fan, air circulation can cause many impurities to enter the evaporator coil, thereby affecting the cooling effect of the refrigeration device.

Due to impurities around the coil, the heat transfer rate of the coil decreases. Because refrigerated trucks may feel less refrigerated after a few years of use, apart from their own reasons, it is because the coils are too dirty and need to be cleaned.

In summary, to ensure the quality of products during refrigerated transportation, it is necessary to first ensure the circulation of cold air and maintain the cleanliness of the carriage. In order to ensure the cleanliness of the transportation floor, it is crucial to ensure the normal operation of the refrigeration unit for refrigerated transportation. Therefore, it is necessary to shorten the opening time as much as possible and use curtains as much as possible. The correct operation and use of refrigerated trucks are key to ensuring the quality of temperature controlled goods and the normal operation of refrigeration equipment.
