Detailed explanation of the correct operation and use of the refrigerated truck and insulated truck

The frozen car has entered the Chinese market for more than 20 years, especially in the past 10 years. It has been widely used in food, medicine, chemical products, electronic 
products, flowers, high-end clothes and high-grade furniture. Associated. Its purpose is to ensure product quality and stability. But the use of product damage and other 
phenomena still exist, correct the reason, mainly due to the use of refrigerated trucks is not correct. So how should we use a freezer? 
1. The correct operation ensures that the goods can be stored and transported in good condition and the guaranteed temperature is the key to the freezer The freezer is specifically designed for use in temperature-sensitive products. 
2. Preventive maintenance minimizes maintenance and operating costs. In our normal use of the process, the vehicle and refrigerator maintenance and maintenance are inseparable. 
Only when the correct time for the equipment maintenance and repair, in order to ensure the normal use of equipment and extend the service life of equipment. Scientific 
maintenance and maintenance, not only can guarantee the equipment in good condition, but also can reduce operating costs. 
3. Proper packaging is essential to protect the goods. For frozen goods with non-ventilated box, the fresh side of the wall with a ventilated cargo box. The crates must be 
compressive. As the frozen cargo is not allowed to have the wind blowing from the surface, so as not to loss of moisture in the goods, thus affecting the quality of goods decreased. The fresh items because of its own characteristics, product storage and transportation process is still in the breathing state, if not ventilated goods will degenerate damage. So this kind of goods have very good ventilation and ventilation. 
4. Set the thermostat at the required temperature, pre-cooling the car 1.5 hours to drain away the stuck in the trunk of the heat; loading the refrigeration unit is closed, rapid loading. During loading, the compartment must be pre-cooled or preheated. Because the vehicle parked in the open air, usually compartment temperature is the ambient 
temperature. If the temperature of the goods transported is not the ambient temperature, the goods loaded into the compartment, the ambient temperature will affect the 
temperature of the transported goods, resulting in the quality of the goods transported change. 
5. Goods must be pre-cooled to the required temperature, check the cargo temperature when loading; freezer is used to maintain the temperature of the goods, rather than to 
reduce the temperature of the goods. Many users of refrigerated trucks have a misconception that refrigerators on refrigerated trucks are free to freeze or heat the goods loaded into the compartment to the temperatures they require. By a certain period of time the temperature of the goods to drop or rise to its desired temperature. However, 
contrary to the facts, but the goods damaged or deterioration. Because the refrigerator car refrigeration unit is not to reduce the temperature of the goods, but to maintain the 
temperature of the goods. Therefore, when loading, you must first measure the temperature of the goods loaded. The storage temperature of the cargo must be the same as the transport temperature. 
6. Even if the unit capacity exceeds the actual requirements, air circulation will lead to deterioration of goods is the main reason; any obstruction around the goods may lead 
to ------ "hot spots." A qualified refrigerated truck, must ensure that the car six sides have better ventilation, six sides of the goods without any obstruction; good air circulation, can ensure that the goods in the appropriate temperature requirements of transport. The cold (hot) gas blown out of the chiller unit isolates the cold (hot) source from the outside into the compartment, thereby protecting the cargo. 
7. The goods must be stacked on the double-sided pallets; preservation of cargo pallets can not be wrapped with plastic film, the film will block circulation of cold air flow to the goods; non-blocking goods under the floor. General refrigerated car floor is the use of aluminum rail with ventilation floor; but there are some freezer is the use of flat non-slip floor. Usually used as third-party transport companies or dairy products for enterprise truck is the use of flat non-slip floor, the purpose is suitable for a variety of products, transportation, or to facilitate cleaning the ground. But must pay attention to loading, be sure to use double-sided pallet to load to ensure the flow of cold air on the ground. 
8. Do not stack the cargo before the outlet of the evaporator, otherwise it will obstruct the flow of cold air. The obstruction above the cargo will cause the cold air flow to short circuit. Maintain a minimum distance of 225 mm between the top of the cargo and the roof. If the front of the outlet blocked by the goods or too close to the goods, not only will affect the storage and transportation of goods temperature, but also affect the normal operation of the refrigeration unit. On the other hand, some of the defrost design of the refrigeration unit is the use of air induction defrost. When the goods and the outlet is too close, the unit evaporator coil will quickly frost (or ice), air sensor switch then action, the unit will quickly enter the defrosting state, so the unit will appear the cycle of the above operations, and thus Leading to the temperature inside the car is not down the phenomenon. For everyone's perception is that the unit is always frequent defrosting. 
9. The interior must be kept clean; the ground should not leave the wrapping paper and scraps of paper; debris will impede the flow of air or by the evaporator inhalation. When 
using a refrigerated truck, keep the floor clean. Due to the action of the evaporator fan, the air circulates inside the compartment, causing the ground shreds or dirt to be 
inhaled by the evaporator fan. The role of a long time, will make a lot of impurities inhaled into the evaporator coil, thus affecting the refrigeration unit cooling effect. 
Because the coil will be surrounded by a little bit of impurities, leading to the coil heat exchange rate decreased. 
10. When the doors open should be closed freezer; as far as possible to shorten the door open time; loading and unloading goods as far as possible when the use of strip curtain. 
Separate dry goods (empty baskets) and perishables with partitions. Proper operation and use of frozen vehicles, is to ensure the quality of the key temperature control of 
goods. But also to ensure that the cooling equipment to work properly where.
