Lots of supermarket have to rely on the refrigerated trucks or refrigerated vans to deliver fresh frozen foods, and during the frozen transportation, the temperature controlled is very important to make sure cargoes fresh. Also, the temperature controlled well is not only depended on high quality truck refrigeration or van refrigeration, but also need some smart tips that transporters take. Usually, resulting in truck refrigeration or van refrigeration not refrigerating well have many reasons, such as truck body insulation not good or much dust or frost in condenser are common to see that in the cold chain transportation.
1.Poor insulating effect and poor sealing of refrigerated truck body
High quality of refrigerated truck bodies are one of reason that guarantees best refrigerating effect. Besides that, when choose refrigerated truck bodies, customers also should take humidity resistance performance into consideration, because if the truck bodies are humid, it may be out of shape, even corrupted, which result in the poor insulating effect and temperature down slowly in truck bodies. Another reason is that poor sealing, and hot air flow goes into truck bodies. When you see moisture consideration in the sealing areas, it means that poor sealing in this areas. What’s more, frequently open door can also result in much hot airflow into, so in this condition, a large cooling capacity longest lasting truck refrigeration unit is best choice.

2.Much dust or frost attach to evaporator
We all know that truck refrigeration evaporator or van refrigeration evaporator installed in the internal truck body or van body. It blows refrigerating airflow evenly into cargoes,keep cargoes fresh, so if there are much dust or frost attached to evaporator, it will result in heat exchange and bad refrigerating effect. So transporters should defrost and clean evaporator regularly. There are two ways that help you to defrost in transport refrigeration units evaporator.
âï¿½ ãï¿½ï¿½Stop truck engine to defrost. That is to say, stop truck refrigeration units compressors running, then open door until the frost melt when temperature is growing in the truck body and restart compressor to run.
âï¿½¡ãï¿½ï¿½Defrosting with hot water. Remove cargoes in truck bodies and flush frost in the evaporator tube with hot water until defrosting.
To make a conclusion, these are two commonly to see reasons above that will result in your refrigerated trucks not good refrigerating effect. Now, please check whether you have noticed the reasons above!
