What can result in the bad cooling effect of your truck’s refrigeration?
Many supermarkets have to rely on refrigerated trucks or refrigerated vans to deliver fresh frozen foods, and during frozen transportation, controlled temperature is very important to ensure loads are fresh. Also, good temperature control not only depends on high-quality truck or van refrigeration, it also needs some smart tips that shippers take. Usually the truck refrigeration or van refrigeration does not refrigerate well for many reasons, such as the truck body insulation is not good, or there is a lot of dust or frost on the condenser, which is common to see in the cold chain transportation.
1. Poor insulation effect and poor sealing of refrigerated truck body
The high quality of refrigerated truck bodies is one of the reasons that guarantees the best refrigeration effect. In addition to that, when choosing refrigerated truck bodies, customers should also consider the moisture resistance performance, because if the truck bodies are wet, they may be out of shape, even corrupted, resulting in poor insulating effect and the temperature drops slowly in the truck. monkeys Another reason is poor sealing and hot airflow into truck bodies. When you see moisture consideration in the sealing areas, it means the sealing is poor in these areas. In addition, the frequently opened door can also generate a lot of hot air flow, so in this condition, a truck refrigeration unit with a large cooling capacity and more durable is the best option.

2. A lot of dust or frost adheres to the evaporator
We all know that truck refrigeration evaporator or van refrigeration evaporator is installed in the inner body of the truck or van. It blows the cooling airflow evenly on the loads, keeps the loads cool, so if there is a lot of dust or frost attached to the evaporator, it will cause heat exchange and bad cooling effect. Therefore, carriers should regularly defrost and clean the evaporator. There are two ways to help you defrost in the evaporator of transport refrigeration units.
â� ã��Stop truck engine to defrost. That is, stop the operation of the compressors of the refrigeration units of the truck, then open the door until the frost melts when the temperature is rising in the body of the truck, and restart the compressor to work.
��Defrost with hot water. Remove loads on truck bodies and wash frost on evaporator tube with hot water until thawed.
To come to a conclusion, here are two of the above commonly mentioned reasons that will result in your refrigerated trucks not having a good cooling effect. Now, check if you have noticed the above reasons!
