Top 10 Common Misconceptions About Reefer Trucks

Sep 04, 2024

There are some common misconceptions about refrigerated truck transportation. Understanding these misconceptions can help you better manage your cargo and ensure effective transportation.

Misunderstanding 1:The choice of transport refrigeration unit cooling capacity the larger the better?
Answer:  Wrong. Refrigeration capacity is not the only measure of refrigerated truck performance standards. Refrigeration capacity is too large or too small will have a negative impact on the preservation of goods. The appropriate refrigeration capacity should be selected according to the type and quantity of the transported goods, as well as the transportation distance and other factors, to ensure that the temperature of the goods is stable and not too cold or too hot.

Myth 2:Can the refrigeration unit reduce the temperature of any transported goods to the minimum temperature?
Answer :  Wrong. The main purpose of the refrigeration unit is to keep the temperature in the cargo hold stable, not to directly reduce the temperature of the cargo.

Myth 3: Doesn't the cargo need to be pre-cooled before packing?
Answer:  Wrong. The insulated box of refrigerated truck provides heat preservation function, and the refrigeration unit is used to maintain the temperature stability of the cargo, so both the cargo and the compartment need to be pre-cooled in advance.

Myth 4: Is there no requirement in the crating of goods?
Answer:  Wrong. When loading cargo in a refrigerated truck, it is recommended to store the cargo in a cool place and pre-cool it in advance.

Myth 5: Is it difficult to cool down the goods with low temperature and easy to cool down the goods with high temperature during transportation?
Answer: Wrong. In the process of transportation, whether it is low-temperature goods or high-temperature goods, the main role of the refrigeration unit is to maintain the stability of the temperature of the goods, rather than a substantial cooling or warming.

Myth 6: The less the goods are transported, the easier it is to reduce the temperature?
Answer: Wrong. Relatively speaking, the more cargo loaded, the smaller the volume of air in the box, which will increase the demand for refrigeration capacity of the refrigeration unit, resulting in faster cooling speed!

Myth 7: The temperature of the refrigeration unit monitor rises, proving that the temperature of the goods is rising?
Answer: Wrong. The temperature on the display of the refrigeration unit only represents the temperature of the air around the evaporator of the chiller, rather than the actual temperature of the goods.

Myth 8: The temperature on the display of the transport refrigeration unit is lower than the required temperature of the goods, does it mean that the refrigeration unit is invalid?
Answer:  Wrong. It takes some time for the refrigeration unit to reduce the temperature in the cargo hold to the set value after loading the cargo. This process is influenced by a number of factors, such as the initial temperature of the cargo, the insulation performance of the cargo hold, etc. Therefore, just after loading, the temperature on the display is lower than the required temperature of the goods is a normal phenomenon, with the passage of time, the temperature will gradually stabilize at the set value.

Myth 9: refrigeration unit as long as the work, there is no need to check the maintenance?
Answer: Wrong. Before each trip of refrigerated truck, the driver should check the tightness of the belt by himself. If the belt is loose, it will slip, affecting the efficiency of the compressor and weakening the refrigeration effect.

Myth 10: What are the non-unit reasons for poor refrigeration effect?
Answer:
◆Cargo is not pre-cooled and its own heat production is large, resulting in increased refrigeration load.
◆The condenser is blocked or dirty, affecting the refrigeration efficiency.
◆Poor air flow in the compartment, resulting in uneven distribution of cold air.
◆Improper selection of insulation box material, structure, insulation material, as well as box plate sealing process problems, will affect the effect of maintaining the temperature in the compartment.

Knowing and avoiding these misunderstandings will help you operate refrigerated vehicles more efficiently and keep your goods fresh.
