The understanding of the refrigerated truck may easily lead to misunderstanding that the refrigerated truck is a cold storage and can freeze the cargo inside the compartment to the required temperature. The role of the refrigerating unit of a refrigerated truck is to maintain the temperature of the goods, not to reduce the temperature of the goods. This insulation principle is like the quilt used to sell cold drinks in the past. It is wrapped in cold drinks to maintain the temperature of cold drinks. When the external temperature enters the body of a refrigerated truck through radiation, conduction, and convection, it will have an impact on the quality of the cargo, so the refrigerated truck will have to function as a refrigeration unit to take away the outside temperature, so as to ensure the temperature of the cargo. Keep the goods at the necessary transport temperature, otherwise they may deteriorate. The main difference between a refrigerated truck and a general van is that a refrigerated truck is equipped with a free-standing or non-freezing refrigerating unit, and a high-quality insulation material is used to make the sealed compartment. The refrigeration unit is divided into independent and non-independent. The independent refrigeration unit must be equipped with an independent battery and diesel engine. The non-freezing refrigeration unit does not require the installation of other accessories. It can rely on the power of the car engine to make it work. So that the minimum temperature in the matching compartment can reach minus 18 °C. Compared with non-freezing refrigeration units, free standing refrigeration units are much more refrigerative than non-independent refrigeration units, allowing the matching compartment temperature to reach a minimum of 28°C. Standalone refrigeration units have a The advantage is that it will not affect the effect of refrigerating and fresh-keeping due to the failure of the car itself, so the cost will be higher in the production cost. The goods need the necessary transportation temperature or they may be degraded. When loading, the temperature of the goods must be checked. If the temperature is too high or too low to enter the carriage, and you want to set through the refrigeration unit to the transportation of the goods you need. Temperature, the result of this will only be counterproductive, and the temperature of the goods will not only fall down or not rise, but will also destroy the goods. The cooling air blown by the refrigeration unit will change the temperature required by the goods and cause the loss of water in the goods. This will also change the quality of the goods, resulting in a decline in the quality of the goods and even mildew.
