[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples.

[0031] To address the technical problem of low accuracy in handling refrigerant leaks in existing technologies, this application provides an air conditioning operation control method, system, device, and air conditioner. By using sensors at different locations to detect the refrigerant concentration in both operating and off states, the detection flexibility is improved, enabling more timely and accurate detection of refrigerant leaks.

[0032] Figure 1 This is a flowchart illustrating an air conditioning operation control method provided in this embodiment, as shown below. Figure 1 As shown, the method may include:

[0033] S10: Based on whether the air conditioner is in operation or off state, determine the refrigerant concentration by using the first sensor corresponding to the operation state and / or the second sensor corresponding to the off state;

[0034] S20: In response to the refrigerant concentration reaching a preset threshold, a preset processing operation is performed; wherein the first sensor and the second sensor are located in different positions in the air conditioner.

[0035] The air conditioning operation control method provided in this embodiment can be applied to air conditioners, such as in air conditioning control systems, or to servers or other terminals that have the ability to control air conditioners, such as terminal devices that connect to air conditioners via Bluetooth, local area networks or other means to control the operation of air conditioners.

[0036] In this embodiment, the air conditioner being in operation can refer to it being in cooling, heating, fan, dehumidifying, or other operating states. The air conditioner being in shutdown state can refer to it being in standby or hibernation state, etc.

[0037] In one embodiment, the refrigerant can be the refrigerant used in an air conditioner, and both the first sensor and the second sensor are refrigerant detection sensors. The first sensor and the second sensor can be set in different locations in the air conditioner, for example, in different locations of the indoor unit of the air conditioner.

[0038] In one embodiment, the preset threshold may be a danger threshold characterizing an abnormal refrigerant leak, such as a refrigerant concentration reaching a level that could cause combustion or explosion. Optionally, the preset threshold may be a fixed value, or it may be a value that can be adjusted based on at least one of the following: room size, season, or air conditioner operating status.

[0039] For example, in summer, rooms tend to have their doors and windows open, while in winter, they tend to have them closed. Therefore, the preset threshold for summer can be higher than the preset threshold for winter.

[0040] In one embodiment, step S10 may include: in response to the air conditioner being in a powered-off state, determining the refrigerant concentration detected by a second sensor corresponding to the powered-off state. For example, the second sensor may be located in the indoor unit of the air conditioner.

[0041] In one embodiment, step S10 may include: in response to the air conditioner being in an operating state, determining the refrigerant concentration detected by a first sensor corresponding to the operating state and / or a second sensor corresponding to the off state. For example, the first sensor may be located at the air outlet of the indoor unit of the air conditioner.

[0042] In one embodiment, step S10 may include: in response to the air conditioner being in an operating state, and the operating state being a cooling state, determining the refrigerant concentration detected by a first sensor corresponding to the operating state. Therefore, in the cooling state, the refrigerant pipeline releases refrigerant to deliver cool air, and the refrigerant concentration can be detected more accurately based on the first sensor.

[0043] In one embodiment, step S10 may include: in response to the air conditioner being in operation and the indoor unit of the air conditioner not being in operation, determining the refrigerant concentration detected by the second sensor corresponding to the off state. Therefore, in the cooling state, the refrigerant pipeline releases refrigerant to deliver cool air, and the refrigerant concentration can be detected more accurately based on the first sensor.

[0044] Optionally, step S10 may further include: in response to detecting that the indoor unit has started to operate, switching to detecting the refrigerant concentration through the first sensor corresponding to the operating state.

[0045] In one embodiment, step S10 may include: in response to the air conditioner being in an operating state, and the operating state being a non-cooling state, determining the refrigerant concentration detected by the second sensor corresponding to the off state. For example, the non-cooling state could be a heating state, a dehumidifying state, etc. Therefore, since no refrigerant is released in the non-cooling state, which is essentially equivalent to the off state, the second sensor in the indoor unit can more accurately and promptly detect refrigerant leakage.

[0046] In one embodiment, step S10 may include: in response to the air conditioner being in an operating state, and the operating state being a fan-operated state, determining the refrigerant concentration using a first sensor corresponding to the operating state and a second sensor corresponding to the off state. Therefore, although no refrigerant is released in the fan-operated state, the airflow will propel the location of leaking refrigerant. Thus, using two sensors simultaneously for detection in uncertain situations can improve detection accuracy.

[0047] In one embodiment, responding to the refrigerant concentration reaching a preset threshold may include: if it is determined that the refrigerant concentration is detected by a first sensor or a second sensor, responding to the refrigerant concentration detected by the first sensor or the second sensor reaching the preset threshold; if it is determined that the refrigerant concentration is detected by a first sensor and a second sensor, responding to the refrigerant concentration detected by at least one of the first sensor and the second sensor reaching the preset threshold.

[0048] In one embodiment, performing a preset processing operation in step S20 may refer to performing a preset processing operation to reduce the refrigerant concentration. For example, the preset processing operation may include at least one of the following: stopping refrigerant delivery, turning on the exhaust function, and stopping the supply air function.

[0049] Stopping refrigerant delivery may include closing the shut-off valve of the refrigerant pipeline; activating the exhaust function may include opening the exhaust valve; and stopping the air supply function may include closing the air supply valve.

[0050] In this way, by using sensors at different locations to detect refrigerant concentration in both the running and off states of the air conditioner, the concentration can be flexibly detected based on the different diffusion rates of the refrigerant in the running and off states. This avoids the inability to detect refrigerant leaks in different states due to the use of a single sensor, thus improving the flexibility and accuracy of refrigerant detection and ultimately enhancing safety.

[0051] Since the air conditioner does not blow air or supply refrigerant when it is off, any accidental refrigerant leak will spread very slowly, making it difficult to detect in time if the sensor is located far away. Therefore, Figure 2 This is a flowchart illustrating an air conditioning operation control method provided in this embodiment, as shown below. Figure 2 As shown, step S10 may include:

[0052] S11: In response to the air conditioner being turned off, control the fan in the indoor unit of the air conditioner to run at a predetermined speed;

[0053] S12: Determine the refrigerant concentration detected by the second sensor corresponding to the shutdown state; the second sensor is located in the indoor unit and the distance from the fan is less than a predetermined distance.

[0054] In one embodiment, the air conditioner includes an indoor unit and an outdoor unit. The indoor unit can also be called an indoor air supply unit, and the outdoor unit can also be called an outdoor unit. The indoor unit is used for supplying air to the room and exhausting air to the outside. The indoor unit may include an air outlet, which can be connected to an air supply duct via an air supply duct and to an air exhaust duct via an air exhaust duct. The air supply duct supplies air to the room through the air supply duct, and the air exhaust duct exhausts air to the outside through the air exhaust duct.

[0055] In one embodiment, the second sensor corresponding to the off state can be installed in the indoor unit, that is, inside the indoor unit, so as to avoid the refrigerant accumulating to a high concentration inside the indoor unit when the indoor unit is not blowing air, which is still difficult to detect at the air outlet.

[0056] In one embodiment, the fan in the indoor unit can be a supply fan used to blow air through the air outlet during operation, or it can be a separate circulating fan that is different from the supply fan. The fan can be located on the side of the indoor unit where the air outlet is located.

[0057] In one embodiment, the second sensor can be located in the middle of the indoor unit, for example, between the fan and the evaporator of the indoor unit, so as to accurately capture the refrigerant leakage concentration from different locations.

[0058] In one embodiment, the distance between the second sensor and the fan is less than a predetermined distance, which can be 1 / 2, 1 / 3, or 1 / 4 of the length or width of the indoor unit, etc.

[0059] In one embodiment, the predetermined speed may be lower than a preset lower limit value. For example, the preset lower limit value may be a speed that consumes less energy and allows the refrigerant to diffuse into the interior of the indoor unit more quickly.

[0060] In one embodiment, the predetermined speed is lower than the operating speed of the fan when the indoor unit is running. For example, the predetermined speed may be lower than or equal to a predetermined percentage of the operating speed, such as 10%, 5%, or 3%.

[0061] Thus, when the indoor unit is not running in the off state, the slow operation of the internal fan can accelerate the diffusion of refrigerant. The refrigerant concentration can then be detected by the sensors inside the indoor unit, preventing the refrigerant from accumulating to a high concentration inside the indoor unit and remaining undetectable by the external sensors, thereby improving detection accuracy and safety.

[0062] In some embodiments, step S10 may further include:

[0063] In response to the air conditioner being in operation, the refrigerant concentration is determined by the first sensor corresponding to the operation status; the first sensor is located at the air outlet of the indoor unit of the air conditioner.

[0064] In one embodiment, the first sensor corresponding to the operating status can be located at the air outlet, for example, the distance between the first sensor and the air outlet is less than a predetermined distance. This allows for rapid detection of the refrigerant concentration in the air discharged from the indoor unit, avoiding inaccurate detection due to refrigerant being discharged from inside the indoor unit with the airflow.

[0065] In one embodiment, the above steps may include: in response to the air conditioner being in operation and the indoor unit being in working state, determining the refrigerant concentration detected by the first sensor corresponding to the operation state. This avoids inaccurate detection when the indoor unit is not working during the operation state.

[0066] In one embodiment, the above steps may include: in response to the air conditioner being in operation, determining the refrigerant concentration using a first sensor corresponding to the operation state and a second sensor corresponding to the off state. For example, in response to the air conditioner being in operation and the air conditioner's fan speed being lower than a predetermined fan speed, determining the refrigerant concentration using the first sensor corresponding to the operation state and the second sensor corresponding to the off state. Therefore, for cases with low fan speeds, detection can be performed simultaneously using both internal and external sensors of the indoor unit, further improving detection accuracy.

[0067] In one embodiment, the first sensor is located near the air outlet outside the indoor unit of the air conditioner. For example, "near the air outlet" can mean that the distance between the first sensor and the air outlet is less than a predetermined distance. The predetermined distance can be 1 / 2, 1 / 3, or 1 / 4 of the length or width of the indoor unit, etc.

[0068] In this way, when the indoor unit is blowing air during operation, the sensor at the air outlet can detect the refrigerant concentration, which can prevent the refrigerant from spreading rapidly with the air and making it difficult to detect the accurate concentration inside the indoor unit, thereby improving the accuracy of the detection.

[0069] Because when refrigerant leakage reaches a dangerous threshold, it is necessary to reduce the refrigerant concentration as quickly as possible and decrease the amount of refrigerant in the room. Therefore, Figure 3 This is a flowchart illustrating an air conditioning operation control method provided in this embodiment, as shown below. Figure 3 As shown, step S20 may include:

[0070] S21: In response to the refrigerant concentration reaching a preset threshold, if the air conditioner is in operation, the refrigerant pipeline shut-off valve of the air conditioner is closed, and the supply air valve is closed and / or the exhaust air valve is opened.

[0071] In one embodiment, the refrigerant line can be a line connecting to the indoor unit to supply refrigerant, and the shut-off valve can be a valve in the refrigerant line that controls the opening and closing of the refrigerant line. Closing the shut-off valve of the air conditioner's refrigerant line controls the refrigerant line to shut off, stopping the refrigerant from entering the indoor unit.

[0072] In one embodiment, controlling the refrigerant line shut-off valve of the air conditioner to close may include: controlling the refrigerant line shut-off valve of the air conditioner to close in response to being in a cooling state; and / or, keeping the refrigerant line shut-off valve closed in response to being in a non-cooling state.

[0073] In one embodiment, closing the supply air valve and / or opening the exhaust air valve may include: closing the supply air valve in response to being in a supply air state; and / or opening the exhaust air valve in response to not being in an exhaust air state.

[0074] Optionally, closing the supply air valve and / or opening the exhaust air valve may further include: keeping the exhaust air valve open or opening the exhaust air valve to its maximum opening degree in response to the current exhaust state; and / or keeping the supply air valve closed in response to the current non-supply state.

[0075] In one embodiment, step S21 may be followed by outputting alarm information. For example, outputting alarm information may include outputting alarm information in the form of lights, sounds, text, and at least one other form.

[0076] Here, alarm information can be output via a display screen, speaker, or other terminal devices connected to the air conditioning unit.

[0077] In one embodiment, controlling the refrigerant pipeline shut-off valve of the air conditioner to close, and closing the supply air valve and / or opening the exhaust air valve may include: controlling the refrigerant pipeline shut-off valve of the air conditioner to close, and closing the supply air valve and / or opening the exhaust air valve, and continuously detecting the refrigerant concentration based on a first sensor and / or a second sensor.

[0078] In one embodiment, opening the exhaust valve may include: opening the exhaust valve and setting the exhaust velocity to a predetermined velocity. For example, the predetermined velocity may be the maximum exhaust velocity, or a predetermined multiple of the operating velocity corresponding to the exhaust state.

[0079] Thus, when the refrigerant concentration is detected to have reached a dangerous threshold, the shut-off valve and the supply air valve can be closed to prevent the refrigerant from continuing to enter the room, and the exhaust air valve can be opened to discharge the refrigerant to the outside, thereby quickly reducing the refrigerant concentration.

[0080] In some embodiments, the execution of the preset processing operation may further include:

[0081] If the air conditioner is off, start the indoor unit and open the exhaust valve.

[0082] In one embodiment, when the air conditioner is off, the indoor unit is not running, and neither the air supply nor exhaust functions are activated. Therefore, starting the indoor unit and opening the exhaust valve may include: starting the indoor unit and opening the exhaust valve while keeping the air supply valve closed.

[0083] In one embodiment, starting the indoor unit of the air conditioner may include: starting the indoor unit and increasing the fan speed in the indoor unit to the operating speed. Here, the operating speed is the normal operating speed of the fan when the indoor unit is running.

[0084] In one embodiment, starting the indoor unit of the air conditioner and opening the exhaust valve may include: starting the indoor unit of the air conditioner and opening the exhaust valve, while continuously detecting the refrigerant concentration based on a first sensor. At this time, since the indoor unit has already been started, the accuracy of continued detection based on the second sensor is insufficient, so it is necessary to switch to the first sensor for detection.

[0085] In one embodiment, opening the exhaust valve may include: opening the exhaust valve and setting the exhaust velocity to a predetermined velocity. For example, the predetermined velocity may be the maximum exhaust velocity, or a predetermined multiple of the operating velocity corresponding to the exhaust state.

[0086] In this way, when the refrigerant concentration is detected to have reached the danger threshold, the air conditioner will be activated in time to start working and exhaust the refrigerant as soon as possible to reduce the danger through the ventilation function.

[0087] In some embodiments, after step S20, the method may further include:

[0088] In response to the refrigerant concentration decreasing to below the preset threshold, the preset processing operation is stopped, and the system returns to the operating state or the shutdown state.

[0089] Here, "running state" or "shutdown state" can refer to the running state or shutdown state before the preset processing operation is performed.

[0090] In one embodiment, stopping the preset processing operation and restoring to the running state or the shutdown state may include: stopping the preset processing operation and restoring to the running state before the preset processing operation was performed.

[0091] For example, if the operating state before the preset processing operation is a non-cooling state, restoring the operating state before the preset processing operation can include: keeping the refrigerant pipeline shut-off valve closed.

[0092] For example, if the operating state before the preset processing operation is the cooling state, restoring the operating state to the state before performing the preset processing operation may include: controlling the refrigerant pipeline shut-off valve to open. For example, controlling the refrigerant pipeline shut-off valve to the opening degree before performing the preset processing operation.

[0093] In one embodiment, if the operating state before the preset processing operation is the air supply state, restoring the operating state to the state before executing the preset processing operation may include: opening the air supply valve. For example, opening the air supply valve to the opening degree before executing the preset processing operation.

[0094] In one embodiment, when the operating state before the preset processing operation is a non-exhaust state, restoring the operating state to the state before the preset processing operation may include: closing the exhaust valve.

[0095] In one embodiment, stopping the preset processing operation and restoring to the running state or the shutdown state may further include: stopping the preset processing operation and restoring to the shutdown state before executing the preset processing operation.

[0096] For example, it may include: stopping the indoor unit from operating and restoring the speed of the fan in the indoor unit to a predetermined speed, and / or closing the exhaust valve.

[0097] In this way, when the refrigerant concentration is detected to have dropped below the dangerous threshold, the air conditioner can be restored to its original working state or shut down in a timely manner to avoid affecting normal operation or generating unnecessary energy consumption.

[0098] In some embodiments, restoring to the operating state includes:

[0099] Control the opening of the refrigerant pipeline shut-off valve of the air conditioner, and open the air supply valve and / or close the exhaust valve.

[0100] Here, controlling the opening of the refrigerant line shut-off valve of the air conditioner can be controlled to open the refrigerant line shut-off valve to the opening degree before performing the preset processing operation.

[0101] In one embodiment, opening the air supply valve can refer to opening the air supply valve to the degree of opening before performing a preset processing operation.

[0102] In one embodiment, restoring to the operating state may include: controlling the refrigerant pipeline shut-off valve of the air conditioner to open, opening the supply air valve and / or closing the exhaust air valve, and continuously monitoring the refrigerant concentration for a predetermined period of time using a first sensor and a second sensor. In this way, the risk of the refrigerant concentration not being fully reduced to a safe range can be further mitigated by simultaneously detecting the refrigerant concentration using two sensors.

[0103] In one embodiment, the method may further include: if the refrigerant concentration remains below a preset threshold for a predetermined period of time, then detecting the refrigerant concentration using a first sensor. This can reduce the energy consumption generated by the simultaneous operation of two sensors.

[0104] In this way, by restoring the refrigerant supply and air valves to their original state, the risk of refrigerant leakage can be eliminated and the system can be promptly adjusted back to its original working state to avoid affecting normal operation or generating unnecessary energy consumption.

[0105] This application embodiment also provides an air conditioning operation control system, the system including: a controller, a first sensor and a second sensor; wherein the first sensor and the second sensor are located in different positions in the air conditioner;

[0106] The controller is configured to determine the refrigerant concentration by using a first sensor corresponding to the running state and / or a second sensor corresponding to the off state, based on whether the air conditioner is in a running state or a shut-off state; and to execute a preset processing operation in response to the refrigerant concentration reaching a preset threshold.

[0107] In one embodiment, the air conditioning operation control system applies the air conditioning operation control method described in any one or more of the foregoing embodiments.

[0108] Here, the specific implementation methods of the air conditioner, the first sensor, and the second sensor, as well as the relevant embodiments of the controller's actions, can be referred to the relevant content in the foregoing embodiments, and will not be repeated here.

[0109] This application also provides an air conditioner, which includes the air conditioner operation control system described in the foregoing embodiments, and / or the air conditioner applies the air conditioner operation control method described in any one or more of the foregoing embodiments.

[0110] As one possible implementation method, such as Figure 4As shown in the diagram, 1 is the exhaust damper, 2 is the supply damper, 3 is the supply duct, 4 is the indoor unit fan, 5 is the refrigerant detection sensor inside the indoor unit (the second sensor), 6 is the evaporator of the indoor unit, 7 is the return duct, and 8 is the refrigerant detection sensor at the air outlet (the first sensor). The indoor unit's air outlet duct connects to the outside for exhaust and to the inside for supply. Both the exhaust and supply vents are controlled by dampers. When the indoor unit is operating normally, the supply vent is open and the exhaust vent is closed, providing cooling or heating to the room. When refrigerant leaks, the refrigerant detection sensor detects that the refrigerant concentration has reached the critical combustion value, posing a risk of combustion or explosion. In this case, the supply vent closes, the exhaust vent opens, and the indoor unit operates to expel the air mixed with refrigerant to the outside of the room to prevent an accident.

[0111] like Figure 5 The diagram illustrates the refrigerant leak detection process. In air conditioning systems using flammable refrigerants, if a refrigerant leak occurs in the indoor unit during cooling, heating, or ventilation, a refrigerant sensor will detect it. If the refrigerant concentration reaches a set threshold, the air conditioning control system will respond. First, it will close the outdoor unit's refrigerant shut-off valve to prevent further refrigerant from entering the indoor unit and leaking. Simultaneously, an alarm will sound, and the display panel will display a notification, reminding people in the room to ventilate. The supply air valve will close, and the exhaust air valve will open to reduce the refrigerant concentration in the room. When the indoor unit is off, the refrigerant sensor inside the indoor unit will monitor the leak, and the indoor unit's fan will run slowly to ensure that the refrigerant at the leak point can quickly diffuse to the refrigerant sensor. If a refrigerant leak occurs in the indoor unit and the refrigerant concentration reaches the set threshold, the air conditioning control system will respond and perform a series of actions.

[0112] like Figure 6 As shown in the figure, this application provides an air conditioning operation control device, which may include:

[0113] The detection unit 100 is used to determine the refrigerant concentration by the first sensor corresponding to the running state and / or the second sensor corresponding to the off state, based on whether the air conditioner is in the running state or the off state.

[0114] The execution unit 200 is used to perform a preset processing operation in response to the refrigerant concentration reaching a preset threshold; wherein the first sensor and the second sensor are located in different positions in the air conditioner.

[0115] In one possible implementation, the detection unit 100 is specifically configured to: control a fan located in the indoor unit of the air conditioner to run at a predetermined speed in response to the air conditioner being in a powered-off state; determine the refrigerant concentration detected by a second sensor corresponding to the powered-off state; wherein the second sensor is located in the indoor unit and the distance between it and the fan is less than a predetermined distance.
