1. Refrigerator trucks can guarantee the good preservation and transportation of transported goods only when they have the correct and good operation and use. Refrigerated trucks are designed for use with objects that have a relatively warm sense of temperature, so it is of paramount importance that refrigerated trucks can guarantee a good transport temperature environment. In the case of improper operation, it is possible that the transported goods cannot be stored and transported in good condition.
2. The refrigerated truck wants to have a normal good use process, but it is inseparable from the maintenance and the maintenance of the refrigerating vehicle's refrigerant. As long as the equipment can be properly maintained and maintained on a regular basis, the normal use of the refrigerator can be guaranteed and its service life can be effectively extended. Generally, the engine and chassis of a refrigerated truck need to be maintained and maintained according to the number of trips. However, the refrigerating unit needs to be maintained and maintained according to the operating hours of the engine. The refrigeration unit of a typical refrigerated truck can perform maintenance work when it operates for five to seven hundred hours. At the same time, it is also necessary to regularly replace the vehicle's air filter, oil filter, fuel filter, and check whether the cooling system has leaks and whether the tightness of the belt is within the normal range.
3. Refrigerated trucks need to use side-ventilated packing boxes when transporting fresh foods, and unrefrigerated packing boxes can be used for frozen goods. The packaging used must be resistant to pressure. Because some frozen items do not allow wind to blow from the surface of the object, if there is wind blowing over the surface of the object, there will be a loss of moisture in the goods, which will cause quality problems in the transport of goods. . Now the country has a system that can't be sold for those bulk foods, but must be packaged and sold. However, because fresh food is because of its special characteristics, when the goods are in the process of transportation, it will still be in a state of breathing. If it is not able to get better ventilation, then the goods will be deteriorating. Therefore, when transporting such items, it is necessary to pay attention to ventilation and ventilation.
4. When loading and unloading goods, it is necessary to perform warm-up and pre-cooling preparations for the compartments of refrigerated trucks. Because refrigerated trucks are parked in those open-air environments, the temperature of refrigerated trucks is usually in line with the outside temperature. If the temperature of the articles being transported is not the current environment is stable, when the articles are loaded into the refrigerated vehicle, the temperature of the current environment will absolutely affect the temperature of the transported goods, which will result in the transported goods. The quality has changed. Therefore, when loading, the temperature of the refrigerated truck compartment should be adjusted to the current temperature of the item. However, it is necessary to close the refrigeration unit when unloading. Because after the precooling of the refrigerated car cabin, if it is not turned off, when the door of the car is opened, because the evaporator fan of the refrigerating unit is operating, and the year of the fan is positive pressure, and the back is It is negative pressure. Therefore, at this time, the air-conditioning will be blown out from the upper part of the compartment, but the lower part will quickly suck the heat outside the compartment into the compartment, which will cause the temperature in the compartment of the refrigerated truck to rise. If the chiller is turned off, it will be loaded and unloaded. Because the fan type is in a stopped condition, the flow of air is also stopped. The air pressure inside and outside the cabin is the same, which will make the hot air in the external environment. The speed of passing into the compartment of a refrigerated truck will slow down.
