Many refrigerated truck drivers have encountered this issue: the refrigeration unit is constantly running, yet the temperature inside the refrigerated box never reaches the set temperature. Today, I'll analyze what to do when the refrigeration temperature of a refrigerated truck doesn't drop.

Is the refrigeration unit experiencing a fault?

Is the refrigerator working properly? This is the first thing truckers should confirm. If there's refrigerant leakage, a dirty condenser, abnormal fan motor, and so on, the cooling and temperature reduction capabilities will naturally not reach the preset effect. At this point, it's necessary to have it checked and repaired at a local authorized repair shop.

How effective is the cold storage thermal insulation?

Once the cold machine is confirmed to be functioning normally, it's essential to verify the thermal insulation status of the refrigerated truck. Check for any obvious areas of condensation leakage. If such issues are present, prioritize improving the thermal insulation of the truck's cargo compartment.

Avoid goods blocking the cold machine evaporator

When loading goods into the vehicle, it is important not to pile too much cargo in front of the refrigerated van's evaporator outlet. Otherwise, it will obstruct the circulation of cold air inside the vehicle. Overloading the cargo, with obstructions above the goods, can cause a short circuit in the cold air flow, resulting in the interior temperature never dropping sufficiently.

Maintain a distance between goods and the top of the refrigerated container.

Ensure proper distance between goods and the top of the refrigerated truck during loading. Maintain a clearance of 220mm, and always ensure that the ventilation outlets within the truck are not blocked and are not higher than the outlet's balanced height.

In summary, the interior of the cold storage fails to reach the preset temperature, which is primarily due to the aforementioned reasons. We suggest that friends using the卡车 avoid stacking goods too high or in excessive amounts. Additionally, here's a cold storage tip for you: regardless of the type of cargo, pre-cool the cold storage 1-2 hours ahead of time, as this will enhance the refrigeration effect significantly.
