What Causes Poor Refrigeration Effect of Refrigerated Trucks?

The reasons for the deterioration of the refrigeration effect of refrigerated trucks mainly include the following two points:
First, as the refrigerated truck is used for a longer time, the components of the refrigeration system may age and loosen, which in turn causes refrigerant leakage in the refrigeration system of the refrigerated truck, resulting in insufficient cooling capacity of the refrigeration unit of the refrigerated truck.

Therefore, the vehicle owner will feel that the refrigeration effect is getting worse and worse.
In this case, as long as the refrigerated truck is regularly inspected and maintained, this situation can basically be avoided.

Second, long-term neglect of the hygiene inside the refrigerated truck body results in a decline in refrigeration effect.

The interior of the compartment must be kept clean; there should be no wrapping paper and scraps of paper on the ground; debris will hinder air flow or be sucked in by the evaporator. When using a refrigerated truck, the floor of the compartment should be kept clean. Due to the action of the evaporator fan, air circulates in the compartment, causing debris or dirt on the ground to be sucked in by the evaporator fan. Over a long period of time, a large amount of impurities will be sucked into the evaporator coil, thereby affecting the refrigeration effect of the refrigeration unit. Because the coil will be surrounded by impurities little by little, resulting in a decrease in the heat exchange rate of the coil. Therefore, after using a refrigerated truck for several years, people will feel that the refrigeration effect is not as good as it was at the beginning. In addition to its own fault reasons, it is because the coil is too dirty. Therefore, ensuring the cleanliness of the ground in the compartment is the key to ensuring the normal operation of the refrigeration unit.
