The outdoor temperature is often above 30 degrees Celsius and lasts for a long time. High temperature has a significant impact on food transportation. During transportation, food will deteriorate due to excessive temperature, resulting in food waste. Therefore, refrigerated trucks are needed to transport food. The cooling device in the refrigerated truck keeps the inner cavity of the refrigerated truck at a low temperature for easy transportation.

When the cooling rate needs to be adjusted according to the transported goods, a large amount of electricity will be consumed, resulting in low economic benefits of the device and poor practicality. When a spray device is used for spray evaporation cooling, it is easy to cause the air humidity inside the refrigerated compartment to be too high, and there is a lack of corresponding dehumidification devices, resulting in unsatisfactory cooling effects and failure to meet cooling requirements.
