[0002] With the continuous development of economy, people's material needs for life are getting higher and higher, and fresh food materials are needed in all seasons to meet people's increasing demand for life. In recent years, the cold chain logistics industry has developed rapidly, and fresh fruits and vegetables can be transported to various places through cold storage transportation in all seasons, thereby ensuring the fresh taste when people eat.
[0003] However, due to the inevitable leakage of cold and other reasons in the cold storage process of the refrigerated vehicle box, the temperature in the refrigerated vehicle box slowly rises, and when the temperature rises to 0℃, the ice condensed in the vehicle box begins to melt to form water droplets, causing the humidity in the vehicle box to increase. If the humidity exceeds the suitable range for the preservation of fruits and vegetables, it will inevitably affect the quality of fruits and vegetables and even cause them to rot, which will also cause huge economic losses to the cold chain logistics industry. Similarly, when industrialized vegetables are planted, a large amount of seeds need to be transported, and if the humidity in the box exceeds or is lower than the suitable storage range of the seeds, it will also cause corresponding losses to the cold chain industry.

Example Two
[0067] In a specific embodiment, referring to Figure 1, the vehicle box 14 is a vehicle box for refrigeration, when the refrigerated vehicle box is loaded with fruits and vegetables for transportation, the humidity in the refrigerated vehicle box needs to be kept at 80% to 90%, after setting the humidity range by the background, at this time the humidification system is running, and more cycles are humidification cycles. The driver only needs to press the start button in the cab, at this time the b and c interfaces of the first three-way electromagnetic valve 7 are opened, the a interface is closed, the b and c interfaces of the second three-way electromagnetic valve 11 are opened, the a interface is closed, the first one-way electromagnetic valve 8 is opened, and the second one-way electromagnetic valve 10 is opened. At this time, the liquid water in the liquid reservoir 9 will flow into the dehumidifier 5 through the second one-way electromagnetic valve 10, and mix with the desiccant in the dehumidifier 5, so that the desiccant reaches a near-saturated state, at this time the desiccant in the dehumidifier 5 is driven by the first circulating pump 4 to flow to the heat exchanger 3 and enter the regenerator 1, and is sprayed to the regenerator 1 with heat source through the first spray pipe 2. The near-saturated desiccant is heated and has relatively high humidity water vapor passing through the upper pipe of the regenerator 1 to the liquid reservoir 9, and is cooled by the cold source and then flows from the first one-way electromagnetic valve 8 to the first three-way electromagnetic valve 7 and enters the top gap layer 15 of the refrigerated vehicle box, thereby humidifying the refrigerated vehicle box. The water vapor generated in the heat exchanger 3 by the heated desiccant still flows to the liquid reservoir 9 through the top pipe section of the heat exchanger 3, and then is cooled and flows to the refrigerated vehicle box. The non-saturated desiccant in the regenerator 1 flows to the dehumidifier 5 and is mixed with the liquid water in the liquid reservoir 9 to reach a near-saturated state, and then flows to the regenerator 1 under the power of the first circulating pump 4, thereby forming a cycle to humidify the refrigerated vehicle box.
[0068] At the same time, the second circulating pump 12 will flow the air in the refrigerated vehicle box to the liquid reservoir 9 through the second three-way electromagnetic valve 11, and the air wetted by the cooling water in the liquid reservoir 9 can reflow to the first one-way electromagnetic valve 8, through the first three-way battery valve 7 into the refrigerated vehicle box to form a cycle. Until the humidity sensor 13 in the refrigerated vehicle box transmits data within the set range of 80% to 90%, the system automatically enters the stop state.
[0069] Further, the vehicle box 14 is provided with a vehicle box circulating air system, a humidity display system, and a humidity adjusting device connected with the vehicle box circulating air system through the dehumidifier 5 and the liquid reservoir 9, and the humidity display system is connected with the internal environment of the vehicle box. The vehicle box 14 is provided with a humidity sensor 13, and the humidity adjusting device senses the humidity in the vehicle box 14 through the humidity monitoring system, then opens and closes the electromagnetic valves in the system on the monitoring system to humidify the vehicle box 14, thereby effectively controlling the humidity in the vehicle box 14, making the humidity in the vehicle box 14 within the required range, thereby solving the problem of the freshness and quality reduction of the refrigerated vehicle transportation goods caused by the unstable humidity in the refrigerated vehicle box.
[0070] It is worth mentioning that the dehumidification or humidification process can be completed in the cab operation, and the humidity range can be controlled by the vehicle-mounted signal system in the background of the cold chain logistics company. The system is turned on or off through the signal line connected to the display screen in the cab operation. The device includes a dehumidification system and a humidification system, and the single dehumidification or humidification device used by the system is split, as long as each component device of the single system belongs to the scope of the system of the present invention.
[0071] Although the present application is disclosed as above, it is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present application, and therefore the protection scope of the present application should be limited by the scope defined in the claims.
