Although the longer the service life of a refrigerated truck is, it may not be as good as a new car in terms of cooling effect, but it will not be said to have a poor effect. In addition to the situation in which the useful life is really close to being scrapped, the reason why the refrigerated trucks with many years of age are becoming poorly cooled may be due to the following aspects:
1. Since the useful life of refrigerated trucks increases year by year, some parts of the vehicle's refrigeration system will experience normal aging or loosening. As a result, the refrigerant in the refrigeration system of the refrigerated vehicle may be leaked. As a result, the refrigerating capacity of the vehicle becomes insufficient, which may lead to a significant problem in the refrigerating effect of the refrigerated vehicle.
2. The sanitation of the refrigerated truck's thermal compartment should always be kept clean and clean. Whether it is transported goods or empty vehicles, there should not be garbage such as packing paper scraps on the floor of the thermal storage compartment. Because some of the impurities or debris that remain on the ground will impede the air flow, as well as the trash in the coil of the evaporator. This will directly affect the cooling effect of the refrigerant in the refrigerated truck. Because the coils in the evaporator are gradually wrapped up by the accumulated waste, it will directly cause a huge drop in the special exchange rate of steam coils. So when the refrigerated truck is used for many years, it will slowly feel that the cooling effect is not as good as before, so it is in addition to its own fault problems, because the coil in the vehicle evaporator is too dirty Caused by. Therefore, no matter when and where, the sanitation work of the refrigerated car should be done well in order to ensure that the service life and performance of the vehicle will not be reduced.
