[0031] Combination Figure 1-3The air-conditioned clothing includes a wearable body 1 and a refrigeration system 2 installed on the wearable body 1. The refrigeration system 2 includes a refrigerant storage device 21, refrigerant piping, and an electronic expansion valve 22. The refrigerant piping is connected to the refrigerant storage device 21 and is distributed throughout the wearable body 1. The electronic expansion valve 22 is located at the connection between the refrigerant storage device 21 and the refrigerant piping.

[0032] Specifically, the refrigerant piping includes a main refrigerant line 23, an evaporator pipe 24, and a return pipe 25. The main refrigerant line 23 is connected to the refrigerant storage device 21 and is used to transport high-pressure liquid refrigerant. The evaporator pipes 24 are connected to the main refrigerant line 23 and are distributed throughout the wearable body 1, used to achieve heat exchange between the liquid refrigerant and the human body. The return pipe 25 is connected at one end to the evaporator pipe 24 and at the other end to the refrigerant storage device 21, used to transport the gaseous refrigerant after heat exchange in the evaporator pipe 24 to the refrigerant storage device 21. Optionally, the main refrigerant line 23 is located on the longitudinal axis of the back of the air-conditioned garment. The evaporator pipes 24 include multiple lines, which are connected to the main refrigerant line 23 in a certain order and distributed throughout the air-conditioned garment. The end of each evaporator pipe 24 is connected to the return pipe 25. The evaporator pipe 24 includes a capillary tube, used to throttle the high-pressure liquid refrigerant in the main refrigerant line 23 into medium-pressure liquid refrigerant.

[0033] Furthermore, the refrigerant storage device 21 includes a liquid refrigerant storage tank 211, a gaseous refrigerant storage tank 212, and an isolation mechanism 213. The liquid refrigerant storage tank 211 is connected to the inlet of the refrigerant pipeline and is used to supply high-pressure liquid refrigerant to the refrigerant pipeline. The gaseous refrigerant storage tank 212 is connected to the outlet of the return gas pipe 25 and is used to recover the gaseous refrigerant formed after heat exchange in the evaporator tube 24. The isolation mechanism 213 is installed on the connecting pipeline between the liquid refrigerant storage tank 211 and the gaseous refrigerant storage tank 212. Here, the isolation mechanism 213 can be a solenoid valve. Shut-off valves are provided at the outlet of the liquid refrigerant storage tank 211 and the inlet of the gaseous refrigerant storage tank 212.

[0034] In addition, the air-conditioned clothing also includes a controller and a temperature detection module. The temperature detection module includes a first temperature sensor located on the outside of the clothing for detecting the ambient temperature; and second and third temperature sensors located inside the clothing for detecting the back and waist of the wearer. The air-conditioned clothing includes a contact layer, a heat-conducting layer, a piping layer, a heat-insulating layer, and an outer layer. The contact layer is in contact with the wearer, and the second and third temperature sensors are located in this layer. The refrigerant main pipe 23 and the evaporator pipe 24 are located in the piping layer. The first temperature sensor, the refrigerant storage device 21, the return pipe 25, the electronic expansion valve 22, the controller, etc., are located in the outer layer.

[0035] Combination Figure 4 As shown, this disclosure provides a control method for air-conditioned clothing, including:

[0036] S101, when the air conditioner is in cooling mode and the electronic expansion valve is initially open, the controller adjusts the opening of the electronic expansion valve according to the ambient temperature.

[0037] Here, the initial opening of the electronic expansion valve can be set, such as to 50%, which is usually set at the factory. The cooling requirements of the air-conditioned clothing vary depending on the temperature environment. If the electronic expansion valve operates based on the initial opening, it may cause the temperature adjustment rate of the air-conditioned clothing to be too fast or too slow, causing discomfort to the wearer. Furthermore, it may waste refrigerant, which is not conducive to resource conservation. Therefore, after the electronic expansion valve opens and refrigerant flows, the opening of the electronic expansion valve is adjusted based on the ambient temperature. Specifically, the higher the ambient temperature, the larger the opening of the electronic expansion valve. This helps to select an appropriate refrigerant flow rate in the initial operation of the air-conditioned clothing, taking into account the ambient temperature. This allows for temperature adjustment for the wearer while avoiding resource waste.

[0038] S102, after a preset time, the temperature sensor acquires the temperature of the target location inside the wearable device.

[0039] Here, the preset duration can be set to 3-8 minutes. After the electronic expansion valve operates for the preset duration at the opening determined by the ambient temperature, the refrigerant has circulated in the evaporator inside the air-conditioned garment, initially regulating the wearer's body temperature. Subsequently, to ensure optimal comfort for the wearer, the opening of the electronic expansion valve needs to be further adjusted based on the wearer's body temperature to control the refrigerant flow. Here, the target location inside the wearable device refers to the temperature of the wearer's waist and / or back, obtained through second and third temperature sensors. Reducing the heat load on the back and waist in high-temperature environments helps reduce perspiration, thus improving the wearer's thermal comfort. Additionally, the target location can also include the abdomen.

[0040] S103, the controller determines the adjustment scheme of the electronic expansion valve based on the temperature at the target location.

[0041] Here, the adjustment scheme of the electronic expansion valve is determined by the temperature at the target location. Considering the wearer's comfortable temperature tolerance, the cooling load on the waist, back, or abdomen should not be too high. Therefore, the refrigerant flow is adjusted by the temperature of the local target location. Specifically, a target temperature can be set for the target location, which can be set according to the wearer's needs. For example, for people who are sensitive to heat, the target temperature can be appropriately lowered; while for people who are heat-tolerant, the target temperature can be appropriately raised. Then, based on the current temperature and the target temperature at the target location, the adjustment scheme of the electronic expansion valve is determined. If the current temperature is lower than the target temperature, it indicates that the internal temperature of the air-conditioned clothing is low. In this case, the adjustment scheme is to reduce the opening of the electronic expansion valve to reduce the refrigerant flow. Alternatively, if the current temperature is higher than the target temperature, it indicates that the internal temperature of the air-conditioned clothing is high. In this case, the adjustment scheme is to increase the opening of the electronic expansion valve to increase the refrigerant flow. Furthermore, the step size of the adjustment opening can be determined based on the difference between the current temperature and the target temperature. For example, for every 1°C increase or decrease in the difference, the opening of the electronic expansion valve can be increased or decreased by ΔV steps. Alternatively, a difference threshold can be set. If the absolute value of the difference exceeds the threshold, the opening of the electronic expansion valve can be adjusted accordingly. Then, based on the difference, an adjustment strategy can be determined. In this way, when the temperature of the air-conditioned clothing is close to the human body's comfortable temperature, the temperature of the clothing can be precisely adjusted based on the target location, thus improving the wearer's comfort.

[0042] S104, the controller controls the electronic expansion valve to execute the adjustment scheme.

[0043] The control method for air-conditioned clothing provided in this embodiment adjusts the opening of the electronic expansion valve based on the ambient temperature during the initial operation of the clothing. This means adjusting the refrigerant flow rate based on the ambient temperature to allow the clothing temperature to quickly approach the user's preferred temperature. Then, the opening of the electronic expansion valve is further adjusted based on the temperature at a target location inside the clothing. This ensures that the temperature of the clothing meets the user's comfort requirements within the microenvironment created by the user's body and the clothing.

[0044] Optionally, in step S101, the controller adjusts the opening of the electronic expansion valve according to the ambient temperature, including:

[0045] When the ambient temperature is higher than the first temperature, the controller adjusts the electronic expansion valve to increase the first preset opening degree.

[0046] When the ambient temperature is less than or equal to the first temperature, the controller adjusts the electronic expansion valve to reduce the second preset opening degree.

[0047] Here, the first temperature is a set critical temperature value used to characterize whether the ambient temperature is too high, such as 35℃. As an example, when the ambient temperature is high, the opening degree of the electronic expansion valve has a first correspondence with the ambient temperature. When the ambient temperature is too high, the opening degree of the electronic expansion valve has a second correspondence with the ambient temperature. Specifically, in the first correspondence, the rate of change of the electronic expansion valve opening degree with the ambient temperature is less than the rate of change in the second correspondence. In the first correspondence, for every 1℃ change in the ambient temperature per unit time, the opening degree of the electronic expansion valve changes by ΔV1. In the second correspondence, for every 1℃ change in the ambient temperature per unit time, the opening degree of the electronic expansion valve changes by ΔV2. ΔV2 is greater than ΔV1.

[0048] Therefore, a first temperature is set here to define the adjustment degree of the electronic expansion valve. With the electronic expansion valve already at its initial opening, if the ambient temperature is higher than the first temperature, the electronic expansion valve is adjusted to increase the first preset opening. If the ambient temperature is lower than or equal to the first temperature, the electronic expansion valve is adjusted to decrease the second preset opening. The first preset opening is greater than or equal to the second preset opening. In this way, the opening of the electronic expansion valve can be adjusted relatively accurately according to the ambient temperature at its initial opening, ensuring that the opening of the electronic expansion valve matches the current ambient temperature, thus achieving temperature regulation of the clothing under the current ambient temperature.

[0049] Optionally, the target location includes a first target location and a second target location. In step S102, the controller acquires the temperature of the target location inside the wearable body, including:

[0050] The second and third temperature sensors detect the temperature at the first target location and the temperature at the second target location, respectively.

[0051] The controller acquires the average temperature of the first target location and the second target location.

[0052] In this embodiment, after initially adjusting the opening of the electronic expansion valve based on the ambient temperature and running the air-conditioned clothing for a preset time, the opening of the electronic expansion valve is further adjusted according to the temperature of a target location inside the wearable body. Specifically, the first target location and the second target location represent the temperatures of different parts of the wearer, such as the waist, abdomen, or back. Here, the first target location is the back, and the second target location is the waist. To avoid localized overcooling or overheating, this embodiment obtains the average temperature of the target location.

[0053] Optionally, in step S103, the controller determines the adjustment scheme of the electronic expansion valve based on the temperature at the target location, including:

[0054] If the temperature at the target location is lower than the second temperature, the controller determines that the electronic expansion valve should maintain its current opening.

[0055] When the temperature at the target location is greater than or equal to the second temperature, the controller determines that the electronic expansion valve increases the third preset opening degree; wherein, the first temperature is greater than the second temperature.

[0056] Here, the temperature at the target location refers to the average temperature of the aforementioned target location. The second temperature is a temperature close to, but slightly higher than, human comfort temperature. For example, if human comfort temperature is 25℃, then the second temperature can range from 28℃ to 30℃. Thus, when the target temperature is lower than the second temperature, it indicates that the current opening of the electronic expansion valve is effective, and maintaining this opening will allow the air-conditioned clothing to reach a comfortable temperature. When the target temperature is higher than the second temperature, it indicates that the current opening of the electronic expansion valve is insufficient to reach a comfortable temperature. Therefore, in this case, the opening of the electronic expansion valve needs to be further increased. Here, the third preset opening is lower than the second preset opening.

[0057] Optionally, in step S101, the controller determines the initial opening degree of the electronic expansion valve by means of:

[0058] The first temperature sensor acquires the current ambient temperature.

[0059] The controller determines the initial opening degree of the electronic expansion valve based on the difference between the current ambient temperature and the temperature threshold.

[0060] Here, the external environment refers to the environment in which the air-conditioned clothing is located, which can be either outdoor or indoor. The temperature threshold can be set according to needs; here, the ambient temperature value that the human body feels comfortable is used as the temperature threshold, such as 25℃. Further, the opening degree of the electronic expansion valve is determined based on the difference between the current ambient temperature and the temperature threshold. The opening degree of the electronic expansion valve can have a corresponding relationship with the difference, or it can be determined by looking up a table to determine the opening degree of the electronic expansion valve corresponding to the current ambient temperature. In this way, determining the initial opening degree of the electronic expansion valve based on the ambient temperature can effectively avoid excessive refrigerant, which would cause the air-conditioned clothing to be too cold and cause discomfort to the wearer. It can also avoid the problem of insufficient refrigerant, which would prevent the air-conditioned clothing from cooling the wearer.

[0061] Optionally, the controller determines the initial opening degree of the electronic expansion valve based on the difference between the current ambient temperature and a temperature threshold, including:

[0062] V0 = (T ao -T set )*ΔV

[0063] Where V0 is the initial opening of the electronic expansion valve, and T aoT represents the current ambient temperature. set ΔV is the temperature threshold, and ΔV is the minimum adjustment opening of the electronic expansion valve.

[0064] In this embodiment, a minimum adjustment opening of the electronic expansion valve is set, and this opening is used as the minimum adjustment step size for adjusting the electronic expansion valve. As an example, after receiving a cooling control command, the air-conditioned garment detects that the current ambient temperature is 36°C and the temperature threshold is 25°C. The difference between the two is 11°C, and the minimum adjustment opening is 5B; therefore, the initial opening of the electronic expansion valve is 11*5=55B. That is to say, for every 1°C increase in the difference between the ambient temperature and the temperature threshold, the opening of the electronic expansion valve increases by 5B.

[0065] Combination Figure 5 As shown in the embodiments of this disclosure, another control method for air-conditioned clothing is provided, including:

[0066] S201, when the air conditioner is in cooling mode and the electronic expansion valve is initially open, the controller adjusts the opening of the electronic expansion valve according to the ambient temperature.

[0067] S202, the pressure sensor acquires the initial pressure of the liquid refrigerant storage tank and the gaseous refrigerant storage tank; when the opening of the electronic expansion valve changes, the controller controls the isolation mechanism to operate so as to maintain the pressure of the liquid refrigerant storage tank and the gaseous refrigerant storage tank at the corresponding initial pressure.

[0068] S203, after the controller has preset the time, it obtains the temperature of the target location inside the wearable device.

[0069] S204, the controller determines the adjustment scheme of the electronic expansion valve based on the temperature at the target location.

[0070] S205, the controller controls the electronic expansion valve to execute the adjustment scheme.

[0071] In this embodiment, as the liquid refrigerant enters the main refrigerant pipeline, the amount of refrigerant stored in the liquid refrigerant storage tank decreases. The movement of the isolation mechanism is controlled to maintain a constant pressure on the liquid side. Simultaneously, the gaseous side draws back gaseous refrigerant from the refrigeration system, maintaining a constant pressure on the gaseous side. This continues until all the liquid refrigerant on the liquid side is converted into gaseous refrigerant on the gaseous side. Thus, by adjusting the movement of the isolation mechanism, pressure balance between the liquid and gaseous refrigerant storage tanks can be maintained. Specifically, the opening degree of the isolation mechanism can be adjusted according to the rate of pressure change. The faster the rate of pressure change, the larger the opening degree of the isolation mechanism, in order to quickly balance the pressure. Furthermore, it should be noted that the state of the isolation mechanism should be appropriately adjusted after each adjustment of the electronic expansion valve opening.

[0072] Optionally, the detection element detects the liquid level in the refrigerant storage device, and if the liquid level is lower than the liquid level threshold, controls the air-conditioning garment to close and controls the electronic expansion valve to close.

[0073] Here, the amount of high-pressure refrigerant is determined by detecting the liquid level in the refrigerant storage device. If the high-pressure refrigerant is insufficient, the air conditioner will be shut off. Simultaneously, a prompt can be issued to remind the wearer to replenish the refrigerant in time.

[0074] Combination Figure 6 As shown in the embodiments of this disclosure, another cooling control method for air-conditioned clothing is provided, including:

[0075] S301, the first temperature sensor detects the ambient temperature. When the ambient temperature is greater than the temperature threshold, the controller controls the air conditioner to execute the cooling control command.

[0076] S302, when the air conditioner is in cooling mode and the electronic expansion valve is initially open, the controller adjusts the opening degree of the electronic expansion valve according to the ambient temperature.

[0077] S303: After the controller has preset the time, it acquires the temperature of the target location inside the wearable device.

[0078] S304, the controller determines the adjustment scheme of the electronic expansion valve based on the temperature at the target location.

[0079] S305, the controller controls the electronic expansion valve to execute the adjustment scheme.

[0080] In this embodiment, the on / off state of the air-conditioning garment is controlled by detecting the ambient temperature. A temperature threshold is set, and the garment is activated only when the ambient temperature is higher than the threshold. When the ambient temperature is lower than or equal to the threshold, the garment remains inactive. This prevents accidental activation of the garment when cooling is not needed due to user error.

[0081] Combination Figure 7 As shown, this embodiment of the disclosure provides a control device for an air-conditioned garment, including an adjustment module 71, an acquisition module 72, a determination module 73, and a control module 74. The adjustment module 71 is configured to adjust the opening of the electronic expansion valve according to the ambient temperature when the air-conditioned garment is in cooling operation and the electronic expansion valve is initially open. The acquisition module 72 is configured to acquire the temperature at a target location inside the wearable body after a preset time. The determination module 73 is configured to determine an adjustment scheme for the electronic expansion valve based on the temperature at the target location. The control module 74 is configured to control the electronic expansion valve to execute the adjustment scheme.

[0082] The control device for air-conditioned clothing provided in this embodiment adjusts the opening of the electronic expansion valve according to the ambient temperature during the initial operation of the clothing. This means adjusting the refrigerant flow rate based on the ambient temperature so that the temperature of the clothing can quickly approach the user's preferred temperature. Then, the opening of the electronic expansion valve is further adjusted based on the temperature at a target location inside the clothing. This ensures that the temperature of the clothing meets the user's comfort requirements within the microenvironment created by the user's body and the clothing.
