The importance of the correct operation and use of refrigerated trucks is that they are specially used to transport items with special requirements for temperature. Therefore, temperature control is the key to ensuring the integrity of the goods. Only by fully grasping the performance of the refrigerated trucks can the refrigerated trucks be operated correctly to ensure the goods safe delivery.

Maintenance of refrigerated trucks can reduce operating costs. In order to recover costs in time and increase profits, some refrigerated truck owners have used refrigerated trucks for a long period of time without performing daily maintenance and maintenance on the refrigerated trucks. As a result, the engines and refrigerating units of the refrigerated trucks are in working condition for a long time, shortening the refrigerated trucks Service life. Only when the refrigerated trucks and refrigeration units are maintained and maintained on time can the normal use of the equipment and the service life of the equipment be extended. Usually the chassis engine is maintained according to the program, and the refrigeration unit is maintained according to the engine working hours. Usually the refrigeration unit is maintained every 500 to 700 hours. The oil filter element, fuel filter element, and air filter element need to be replaced; and pay attention to check the tightness of the belt and whether there is leakage in the refrigeration system. However, in order to meet the needs of environmental protection and minimize the damage to the environment and reduce the emission of harmful substances, the refrigeration units of individual brands (such as Thermo King) use synthetic or semi-synthetic engine oil to replace ordinary engine oil, thereby extending the engine. The maintenance time is usually performed once every 2000 hours. Therefore, the emission of waste engine oil is reduced. In addition, scientific experiments have proved that by using this high-end engine oil, not only the wear on the engine is reduced, but also the fuel consumption of the engine can be reduced.

Appropriate packaging of refrigerated goods is also an important factor to ensure that the goods can be delivered properly. Different items should be used in different packaging boxes. For frozen goods, use non-ventilated packaging boxes, and for fresh goods, use sidewall ventilated packaging boxes. The box must be squeezed.

Set the thermostat at the required temperature before loading the goods, pre-cool the truck for 1.5 hours to remove the heat trapped in the truck, turn off the refrigerating unit when loading, and load the goods quickly. When the cargo is packed, the compartment must be pre-cooled. Because the truck is parked in the open air, the internal temperature of the refrigerated compartment is the same as the outside temperature. If the temperature of the goods being transported is not the ambient temperature, the goods will be loaded into the compartment. Affect the temperature of the transported goods, resulting in changes in the quality of the transported goods. Therefore, the carriage must be pre-cooled to the required temperature before loading. However, the refrigeration unit must be turned off during loading (the same as unloading). Many people do not turn off the refrigeration unit when loading and unloading goods. In fact, this is a very wrong operation. The correct method of use is to turn off the refrigeration unit when loading and unloading goods.

Goods with different temperature requirements cannot be stored in the same compartment. They should be separated by partitions. Since the refrigerator is used to maintain the temperature of the goods, not to cool them, mixing goods with different temperatures will affect the goods The temperature of the product has affected the quality of goods.

In short, the correct use and maintenance of refrigerated trucks can maximize the utility of refrigerated trucks, maximize the quality of goods, and minimize the operating costs of vehicle owners to earn more profits.
