The refrigeration unit of a refrigerated truck is the main refrigeration equipment, and the quality of the refrigeration unit often affects the service life and fuel consumption of the refrigerated truck. As refrigerated trucks are used for a long time, the cooling effect of the refrigerated compartment will become worse and worse. So what is the reason behind it? Next, the refrigeration unit manufacturer will take us to see the reasons why the refrigeration effect of refrigerated trucks deteriorates after long-term use.

When purchasing a refrigerated truck, when choosing a refrigeration unit, the first thing to consider is the manufacturing process and functional quality, followed by the brand. Generally speaking, foreign refrigeration units have better functions than domestic ones, but the price is slightly higher.

When choosing a domestic brand refrigeration unit, it's not just about functionality and quality, but also about the manufacturer's planned brand influence and reputation. A good refrigeration unit, as well as good maintenance in the later stages of use, will prevent the cooling effect of a refrigerated truck from deteriorating after many years of use.

The issue of refrigeration system failure is caused by the duration of time. As refrigerated trucks are used for a longer period of time, the refrigeration system components may age and loosen, leading to refrigerant leakage in the refrigerated truck's refrigeration system and insufficient cooling capacity of the refrigerated truck's refrigeration mechanism. Therefore, car owners may feel that the cooling effect is getting worse and worse. In this situation, as long as the refrigerated truck can be regularly inspected and maintained, the occurrence of this situation can be basically avoided

Long term neglect of the hygiene inside the refrigerated truck compartment has resulted in a decrease in refrigeration efficiency. When using a refrigerated truck, the floor of the compartment should be kept clean. Due to the effect of the evaporator fan, air will circulate inside the cabin, causing debris or dirt on the ground to be sucked in by the evaporator fan.

The long-term effect will cause many impurities to be sucked into the evaporator coil, which will then affect the refrigeration efficiency of the refrigeration unit. Due to the small amount of impurities surrounding the coil, the heat exchange rate of the coil decreases.

So after using refrigerated trucks for a few years, we may feel that the cooling effect is not as good as it started. Apart from the fault itself, it is caused by the dirty coils. Therefore, ensuring the cleanliness of the floor in the compartment is the key to ensuring the normal operation of the refrigeration unit.
