[0030] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0031] like Figures 1 to 5 As shown, this utility model discloses an AIoT intelligent control three-effect integrated warehouse system, which mainly includes a compressor 1, a condenser 2, an indoor evaporator 3, an outdoor evaporator 4, and a four-way valve 5. The four-way valve 5 has a first interface a, a second interface b, a third interface c, and a fourth interface d. These components are interconnected through connecting pipes to form different circulation loops, enabling multiple operating modes of the system.

[0032] In this embodiment, a liquid storage tank 6 and an electronic expansion valve 7 are sequentially installed on the connecting pipe between the condenser 2 and the indoor evaporator 3 or the outdoor evaporator 4. The liquid storage tank 6 is used to store refrigerant to ensure a stable supply of refrigerant to the system; the electronic expansion valve 7 can precisely control the flow rate of refrigerant and adjust the cooling or heating effect of the system.

[0033] A first check valve 8 is provided between the electronic expansion valve 7 and the outdoor evaporator 4. This first check valve 8 only allows refrigerant to flow in the direction from the outdoor evaporator 4 to the electronic expansion valve 7, preventing refrigerant backflow and ensuring the normal operation of the system. A second check valve 9 is connected to the outlet end of the indoor evaporator 3, which also serves to prevent refrigerant backflow.

[0034] A gas-liquid separator 10 is connected to the refrigerant inlet of compressor 1. Its function is to separate the gas and liquid in the refrigerant to prevent liquid refrigerant from entering compressor 1 and damaging compressor 1.

[0035] An indoor solenoid valve 11 is installed on the connecting pipe of the indoor evaporator 3. By controlling the opening and closing of the indoor solenoid valve 11, it is possible to control whether the indoor evaporator 3 participates in the system circulation. An outdoor solenoid valve 12 is installed on the connecting pipe of the outdoor evaporator 4, which is used to control whether the outdoor evaporator 4 participates in the system circulation.

[0036] A blower 13 is installed near the condenser 2. The blower 13 can accelerate the airflow around the condenser 2 and improve the heat dissipation efficiency of the condenser 2. An outdoor fan 14 is installed near the outdoor evaporator 4. The outdoor fan 14 can promote heat exchange between the outdoor evaporator 4 and the outside air.

[0037] An oil separator 15 is connected to the refrigerant outlet of compressor 1. During refrigeration system operation, some lubricating oil is carried out with the exhaust gas from compressor 1. If a large amount of lubricating oil cannot return to compressor 1, it will lead to insufficient oil supply, accelerated wear of components, shortened service life, and even malfunctions such as bearing seizure, cylinder jamming, or burnout. The oil separator 15 can trap the lubricating oil in the exhaust gas and return it to compressor 1, preventing such situations from occurring.

[0038] The following section will further elaborate on the loops under different operating modes.

[0039] (1) When the system is in drying mode, the first port a of the four-way valve 5 is connected to the second port b, and the third port c is connected to the fourth port d. At this time, the refrigerant circulation path is as follows: the refrigerant outlet of the compressor 1 passes through the first port a, the second port b of the four-way valve 5, the condenser 2, the outdoor evaporator 4, the fourth port d and the third port c of the four-way valve 5 in sequence, and finally returns to the refrigerant inlet of the compressor 1, forming a drying circulation loop.

[0040] In this process, compressor 1 compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant, which then enters condenser 2 through four-way valve 5. In condenser 2, the high-temperature, high-pressure gaseous refrigerant exchanges heat with the surrounding air, releasing heat and becoming a high-temperature, high-pressure liquid refrigerant. Next, after being regulated by liquid tank 6 and electronic expansion valve 7, the liquid refrigerant enters outdoor evaporator 4. In outdoor evaporator 4, the liquid refrigerant absorbs heat from the outside environment, evaporating into a low-temperature, low-pressure gaseous refrigerant, which then returns to compressor 1 through four-way valve 5, completing one cycle. Simultaneously, fan 13 accelerates the airflow around condenser 2, blowing the heat released by condenser 2 into the chamber to achieve the drying purpose.

[0041] (2) When the system is in refrigeration mode, the first port a of the four-way valve 5 is connected to the fourth port d, and the second port b is connected to the third port c. The refrigerant circulation path is as follows: the refrigerant outlet of the compressor 1 passes through the first port a, the fourth port d of the four-way valve 5, the outdoor evaporator 4, the condenser 2, the second port b and the third port c of the four-way valve 5 in sequence, and finally returns to the refrigerant inlet of the compressor 1, forming a refrigeration circulation loop.

[0042] In refrigeration mode, the high-temperature, high-pressure gaseous refrigerant discharged from compressor 1 first enters the outdoor evaporator 4 through the four-way valve 5. In the outdoor evaporator 4, the refrigerant exchanges heat with the outside air, releasing heat and becoming a high-temperature, high-pressure liquid refrigerant. Then, the liquid refrigerant passes through the receiver tank 6 and the electronic expansion valve 7 before entering the condenser 2. In the condenser 2, the liquid refrigerant absorbs heat from the compartment and evaporates into a low-temperature, low-pressure gaseous refrigerant, thereby lowering the temperature inside the compartment. Finally, the gaseous refrigerant returns to compressor 1 through the four-way valve 5. The outdoor fan 14 accelerates the heat exchange between the outdoor evaporator 4 and the outside air, improving the system's cooling efficiency.

[0043] (3) When the system is in drying, dehumidifying and dehumidifying mode, the first port a of the four-way valve 5 is connected to the second port b, and the third port c is connected to the fourth port d. The refrigerant circulation path is as follows: the refrigerant outlet of the compressor 1 passes through the first port a, the second port b of the four-way valve 5, the condenser 2, the indoor evaporator 3, the fourth port d and the third port c of the four-way valve 5 in sequence, and finally returns to the refrigerant inlet of the compressor 1, forming a drying, dehumidifying and dehumidifying circuit.

[0044] In this mode, the high-temperature, high-pressure gaseous refrigerant discharged from compressor 1 enters condenser 2 through four-way valve 5. In condenser 2, it releases heat and transforms into high-temperature, high-pressure liquid refrigerant. The liquid refrigerant then passes through receiver 6 and electronic expansion valve 7 before entering indoor evaporator 3. In indoor evaporator 3, the liquid refrigerant absorbs heat and moisture from the air inside the chamber, cooling and dehumidifying the air. Simultaneously, moisture in the air condenses into water droplets on the surface of indoor evaporator 3 and is discharged outside the chamber through a drainage device. The dehumidified air is then heated again by condenser 2, becoming dry, hot air, which is then blown back into the chamber, achieving the functions of drying, dehumidifying, and removing moisture.

[0045] (4) When the system is in constant temperature mode, the first port a of the four-way valve 5 is connected to the fourth port d, and the second port b is connected to the third port c. The refrigerant circulation path is as follows: the refrigerant outlet of the compressor 1 passes through the outdoor evaporator 4, the condenser 2, the second port b and the third port c of the four-way valve 5 in sequence, and finally returns to the refrigerant inlet of the compressor 1, forming a constant temperature circuit.

[0046] In constant temperature mode, the operating frequency of compressor 1 and the opening degree of electronic expansion valve 7 are adjusted based on the temperature information fed back by the temperature sensor inside the chamber. When the temperature inside the chamber is higher than the set temperature, the control system increases the cooling capacity to lower the temperature inside the chamber; when the temperature inside the chamber is lower than the set temperature, the control system reduces the cooling capacity to raise the temperature inside the chamber, thereby maintaining a constant temperature inside the chamber.

[0047] (5) When the system is in constant temperature and humidity mode, the first port a of the four-way valve 5 is connected to the second port b, and the third port c is connected to the fourth port d. The refrigerant circulation path is as follows: the refrigerant outlet of the compressor 1 passes through the first port a, the second port b of the four-way valve 5, the condenser 2, the indoor evaporator 3, the fourth port d and the third port c of the four-way valve 5 in sequence, and finally returns to the refrigerant inlet of the compressor 1, forming a constant temperature and humidity circuit.

[0048] In constant temperature and humidity mode, the system must not only maintain a constant temperature inside the chamber but also control the humidity within a set range. The system dehumidifies through the indoor evaporator 3 and heats through the condenser 2. Simultaneously, it adjusts the opening of the electronic expansion valve 7 and the operating frequency of the compressor 1 based on humidity information fed back from the humidity sensor, thereby achieving precise control of the temperature and humidity inside the chamber.

[0049] For the drying stage:

[0050] When loading materials, place the harvested agricultural products (such as fungi, fruits, grains, etc.) evenly on the material rack in the drying room, and make sure to keep a certain distance between the materials to ensure that the hot air can circulate evenly.

[0051] For fruits with high moisture content, a low-temperature, segmented drying method is adopted. First, the fruit is initially dried at a lower temperature (e.g., 40-50℃), and then the temperature is gradually increased to 60-70℃ until the required moisture content is achieved. This ensures the drying effect while preserving the nutritional components of the agricultural products to the greatest extent.

[0052] After drying, allow the material to cool to room temperature before removing it from the drying chamber for packaging and storage. Clean any remaining material from the drying chamber to keep the equipment clean and prepare for the next drying cycle.

[0053] For the frozen preservation stage:

[0054] When goods are received into the cold storage, agricultural products requiring freezing and preservation should be sorted and placed in different areas of the cold storage. Ensure that there are sufficient gaps between items to allow for even circulation of cold air and provide a stable preservation environment for the agricultural products.

[0055] Set appropriate cold storage temperatures according to the type of agricultural product and its preservation requirements. For most fruits and vegetables, the preservation temperature can be set between 0-5℃; for meat and seafood, the freezing temperature needs to be set below -18℃ to ensure that different agricultural products receive precise preservation treatment.

[0056] According to demand, frozen and preserved goods are removed from the cold storage. During the outbound process, attention is paid to controlling temperature changes to avoid affecting the quality of the goods due to excessive temperature fluctuations, ensuring that agricultural products enter the market in optimal condition.

[0057] This invention integrates multiple processes such as planting, drying, and freezing preservation, reducing the transfer and handling of agricultural products between different devices and significantly shortening the production cycle. Taking fungi as an example, after harvesting, they can be dried directly within the unit, avoiding the time and labor costs of transferring them to specialized drying equipment in traditional methods, making agricultural production more efficient and faster.

[0058] Through the cyclic loops of the above different working modes, this AIoT intelligent control three-effect integrated warehouse system can meet the diverse needs of different users for the warehouse environment and achieve efficient and intelligent environmental control.

[0059] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
