What should I pay attention to when loading the refrigerated truck?
the refrigerated truck
the refrigerated truck shutdown, avoid cold air pressure factors from entering the insulation box Closed platform loading; quickly loaded the cargo by closed platforms to avoid contact with the external environment, leading to a broken chain of the cold chain. The door should be as small as possible. the refrigerated truck is recommended to use the curtain or the screen to prevent the environmental temperature from passing.
The correct packaging of goods; the requirements for packaging and frozen goods are different. The packaging of fresh goods must be ensured. Plastic packaging cannot be used when transporting fresh goods, because the refrigerated truck hinders the air circulation of the goods and should be used to ensure air circulation.
Different goods are transported separately; different types and temperature requirements cannot be transported in the same compartment, the refrigerated truck and the the refrigerated truck should be divided into independent small compartments separately. Do not mix frozen goods and dry goods in the same compartment.
Leave enough cold air channels; ensure that there is enough gap between the inner wall of the cargo and the cold compartment when loading, the refrigerated truck to ensure that the cold air is smooth, so that the cold wind can pack the goods in each corner, the refrigerated truck which does not cause local temperature rise.
the refrigerated truck are controlled by reflection; when transporting frozen goods, the temperature control method is controlled by the air return temperature. This is the default temperature control method of the cold machine.
Fresh goods are controlled by air supply temperature; when transporting fresh goods, the temperature control method must be controlled by air supply temperature to avoid freezing the goods.
After loading, manual cream again; after the loading is completed, turn off the door and turn on the door, and perform a manual frost for about half an hour. In this way, the evaporator generated by the humid and humid air that enters the load can be frost, the refrigerated truck so that the evaporator can maximize the ability to ensure the safety of the goods.
Stop the refrigerated truck and then open the door; before opening the door, the unit must stop. If the cold machine is not turned off, it will inhale a large amount of external humid and humid air,
causing temperature rise and frost in the inside of the compartment, which will cause difficulties in the later period of cold and waste fuel.Clean thermal insulation and refrigeration units; prevent evaporator polluting goods or blocking cold machines, ensure the cooling effect, the refrigerated truck and ensure the safety of goods. The evaporator and condenser mainly change the surrounding environment by conducting heat exchange with air. In order to better contact the air, it is especially important to keep the surface clean.
Due to the effect of evaporator fan, the air will circulate inside the carriage, causing crushing or dirty things to be inhaled by the evaporator fan. Long term effects will inhale a large amount of impurities into the evaporator’s tray, which will affect the refrigeration effect of the refrigeration unit. Because the tray will be surrounded by a little bit of impurities, the heat exchange rate of the coil will decrease. Therefore, after a few years of use of the refrigerator, everyone will feel that the refrigeration effect is not as good as the beginning. Except for the cause of the failure, it is caused by the ducts of the plate. Therefore, the cleanliness of the ground in the carriage is the key to ensuring the normal work of the refrigeration unit, so regularly clean the condenser and evaporator of the refrigeration unit.
