company news about Reasons for the deterioration of the refrigerating effect of refrigerated vehicles

Many users of refrigerated trucks report that with the longer and longer service life, the cooling effect is getting worse. What is going on? Now I will answer for you.

There are two main reasons for the deterioration of the refrigeration performance of refrigerated trucks:

With the long-term use of refrigerated trucks, the components of the refrigeration system may become aging and loose, which will cause refrigerant leakage in the refrigerated truck refrigeration system, resulting in insufficient refrigeration capacity of the refrigerated truck, so the owner will feel more and more cooling effect difference.

In this case, as long as the refrigerated truck can be regularly inspected and maintained, this situation can basically be avoided.

Second, long-term carelessness in the hygiene of refrigerated trucks has led to a decline in the cooling effect.

The interior of the carriage must be kept clean; there should be no wrapping paper and paper scraps on the ground; the scraps will obstruct the airflow or be sucked into the evaporator. When using a refrigerated truck, please keep the floor clean. Due to the action of the evaporator fan, air will circulate in the train compartment, causing the ground to break or dirt to be sucked in by the evaporator fan. Long-term action will cause a large amount of impurities to be sucked into the evaporator coil, thereby affecting the refrigeration effect of the refrigeration unit. Because the coil will be surrounded by impurities a little bit, the heat exchange rate of the coil will decrease. Therefore, after a few years of refrigerated trucks, everyone will feel that the cooling effect is not as good as at the beginning, except for its own failure, which is the reason for the dirty coil.
