Many supermarkets depend on refrigerated trucks or refrigerated vans to deliver fresh frozen foods, and when transporting frozen goods, temperature control is crucial to keeping the cargoes fresh. Furthermore, in order to keep the temperature under control, transporters must follow some shrewd advice in addition to using high-quality truck or van refrigeration. Many factors, such as poor truck body insulation, a lot of dust, or frost in the condenser, are frequently seen in the cold chain transportation and lead to truck refrigeration or van refrigeration not refrigerating well.

1.Poor insulating effect and poor sealing of refrigerated truck body

One factor that ensures the best refrigerating effect is the high quality of the refrigerated truck bodies. In addition, customers should consider the humidity resistance performance of the truck bodies when choosing refrigerated truck bodies because if the truck bodies are humid, they may be out of shape or even corrupted, which results in a poor insulating effect and a slow cooling of the temperature inside the truck bodies. Poor sealing and hot air flow entering truck bodies are additional causes. When moisture consideration is seen in the sealing areas, the sealing in those areas is poor. A truck refrigeration unit with the most cooling capacity and the longest lifespan is the best option in this situation because frequently opened doors can also cause a lot of hot air to flow in.

2.Much dust or frost attach to evaporator

We are all aware that internal truck bodies or van bodies are where refrigeration evaporators are installed. If there is a lot of dust or frost attached to the evaporator, it will cause heat exchange and have a bad refrigerating effect because it distributes the refrigerating airflow evenly into the cargoes, keeping them fresh. The evaporator should therefore be regularly defrosted and cleaned by transporters. There are two methods for defrosting the evaporator in portable refrigeration units.

â� ã��halt the truck’s engine to defrost. In other words, turn off the compressors for the truck refrigeration units, open the door until the frost melts as the temperature inside the truck body rises, and then turn the compressors back on.

��utilizing hot water to defrost. Take out the cargo from the truck bodies, then use hot water to defrost the frost in the evaporator tube.

To sum up, the two reasons mentioned above that are most frequently seen will prevent your refrigerated trucks from having a good cooling effect. Please verify that you are aware of the aforementioned reasons now.
