Over time, refrigerated trucks may experience a decline in cooling efficiency. Here are the primary reasons why the cooling performance of a refrigerated truck decreases after prolonged use:
1. Initial Selection of Refrigeration Unit:
When purchasing a refrigerated truck, the quality and performance of the refrigeration unit are critical. Consider the manufacturing process, quality of components, and the brand reputation. Foreign-made refrigeration units typically offer better performance, though they may be more expensive. If you opt for a domestic brand, it’s essential to assess both the unit’s performance and the manufacturer’s reputation. Choosing a high-quality unit and maintaining it well can help prolong the truck’s cooling performance over the years.
2. Aging of the Refrigeration System:
As the truck ages, components of the refrigeration system can wear out or become loose. This may lead to refrigerant leaks, which reduce the unit’s cooling capacity. Over time, this can cause the refrigeration performance to decrease noticeably. Regular inspection and maintenance can help identify and address these issues before they significantly affect the truck’s cooling ability.
3. Lack of Hygiene Inside the Truck:
A poorly maintained interior can lead to reduced cooling efficiency. During normal use, dust, debris, and dirt can accumulate on the truck’s floor. The evaporator fan circulates air inside the truck, and over time, debris from the floor can get sucked into the evaporator fan and coils. This build-up reduces the coil’s ability to exchange heat efficiently, leading to a decline in cooling performance. Over time, the coils can become insulated by dirt, causing a noticeable drop in refrigeration efficiency. Therefore, keeping the truck’s interior clean, especially the floor, is crucial for maintaining the refrigeration system’s optimal performance.
In summary, to prevent a decline in cooling efficiency over time, it’s important to select a high-quality refrigeration unit, perform regular maintenance to avoid system wear and tear, and keep the interior clean to maintain proper airflow and heat exchange.
