1. Before loading, the compartment must be pre-cooled or preheated for about 0.5h. Since the vehicle is parked in the open air, the temperature of the compartment is usually higher than that of the outside environment. After the goods are loaded into the carriage, the ambient temperature in the carriage will affect the temperature of the transported goods, resulting in changes in the quality of the transported goods. Therefore, the cabin must be pre-cooled to the necessary temperature before loading.

2. When using a refrigerated truck, the floor of the compartment should be kept clean. Because of the evaporator fan, air circulates in the cabin, causing debris or dust on the ground to be sucked up by the evaporator fan. Over time, a lot of magazines will be sucked into the evaporator coil, which will affect the cooling effect of the refrigeration unit, and there will be no odor in the cabin.

3. When loading, do not stack the goods too high. Make sure that the loading height is not higher than the level of the air outlet. When loading, it must be loaded with double-sided pallets, so as to ensure the circulation of cold air on the ground.
