The refrigeration unit of a refrigerated truck is used to maintain the temperature of goods, prevent them from deteriorating, and maintain their original freshness. So car owners should no longer mistakenly believe that the refrigeration unit of a refrigerated truck is the function of reducing or heating the temperature of goods. Do not fall into this misconception, which may lead to incorrect use of the refrigeration unit of a refrigerated truck and reduce its service life.

The refrigeration unit of a refrigerated truck serves the same purpose as wrapping goods in cotton quilts in the past, preventing external airflow from exchanging heat and cold, which can cause the goods to spoil.

When loading small refrigerated trucks, the carriages must first be pre cooled or preheated. The refrigeration unit must be turned off during loading and unloading. There are some small details to note about the refrigeration unit of the refrigerated truck:

This is because when we pre cool the carriage, if we don't shut down and open the carriage door, because the fan of the refrigeration unit evaporator is working, the front of the fan is positive pressure, and the back is negative pressure, cold air is blown out from the upper part of the carriage, and the lower part will quickly suck in the hot air outside, causing the temperature inside the carriage to rise rapidly.

If the goods are loaded and unloaded after shutdown, due to the fan being in a stopped state, the air flow stops, and the air pressure inside and outside the carriage is consistent, which slows down the speed of external hot air transfer into the carriage.
