[0029] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0030] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0031] In order to solve the technical problem of low accuracy in refrigerant leakage processing in the prior art, the present application provides an air conditioning operation control method, system, device and air conditioner, which detects the refrigerant concentration in the running and shutdown states through sensors at different positions, thereby improving the detection flexibility and detecting refrigerant leakage more timely and accurately.

[0032] Figure 1 A flow chart of an air conditioning operation control method provided in this embodiment is shown as follows: Figure 1 As shown, the method may include:

[0033] S10: Based on whether the air conditioner is in an operating state or an off state, determining to detect the refrigerant concentration through a first sensor corresponding to the operating state and / or a second sensor corresponding to the off state;

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

[0035] The air conditioning operation control method provided in this embodiment can be applied to an air conditioner, for example, in a control system of an air conditioner, or can also be applied to a server or other terminal that has the ability to control the air conditioner, such as a terminal device that is connected to the air conditioner via Bluetooth, a local area network or other means to control the operation of the air conditioner.

[0036] In this embodiment, the air conditioner is in the running state, which may refer to the air conditioner being in the cooling state, heating state, air supply state, dehumidification state or other working state. The air conditioner is in the off state, which may refer to the air conditioner being in the standby state or the dormant state.

[0037] In one embodiment, the refrigerant may be a refrigerant used in an air conditioner. The first sensor and the second sensor are both refrigerant detection sensors. The first sensor and the second sensor may be respectively arranged at different positions in the air conditioner, for example, at different positions of an indoor unit in the air conditioner.

[0038] In one embodiment, the preset threshold may be a dangerous threshold indicating abnormal leakage of the refrigerant, such as a concentration of the refrigerant reaching a concentration that may cause combustion or explosion, etc. Optionally, the preset threshold may be a fixed value, or may be a value adjusted based on at least one of the room size, season, or operating status of the air conditioner, etc.

[0039] For example, in summer, doors and windows of a room are often opened, while in winter, doors and windows of a room are often closed. Therefore, the preset threshold corresponding to summer may be higher than the preset threshold corresponding to winter.

[0040] In one embodiment, step S10 may include: in response to the air conditioner being in a shutdown state, determining to detect the refrigerant concentration through a second sensor corresponding to the shutdown state. For example, the second sensor may be located in an indoor unit of the air conditioner.

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

[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 to detect the refrigerant concentration through a first sensor corresponding to the operating state. Therefore, in the cooling state, the refrigerant pipeline will release refrigerant for sending cold 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 to detect the refrigerant concentration through the second sensor corresponding to the shutdown state. Therefore, in the cooling state, the refrigerant pipeline will release the refrigerant for sending cold 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 starts to work, switching to detecting the refrigerant concentration through a 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-refrigeration state, determining to detect the refrigerant concentration through a second sensor corresponding to the shutdown state. For example, the non-refrigeration state may be a heating state, a dehumidification state, etc. Therefore, no refrigerant is released in the non-refrigeration state, which is basically equivalent to the shutdown state, and the refrigerant leakage can be captured more accurately and timely based on the second sensor in the indoor unit.

[0046] In one embodiment, step S10 may include: in response to the air conditioner being in an operating state, and the operating state being an air supply state, determining to detect the refrigerant concentration through a first sensor corresponding to the operating state and a second sensor corresponding to the shutdown state. Therefore, although the refrigerant is not released in the air supply state, the air supply will push the location of the leaked refrigerant, so using two sensors for simultaneous detection in uncertain situations can improve the detection accuracy.

[0047] In one embodiment, in response to the refrigerant concentration reaching a preset threshold, it may include: if it is determined that the refrigerant concentration is detected by the first sensor or the second sensor, in response 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 the first sensor and the second sensor, in response 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, the preset processing operation performed in step S20 may refer to the preset processing operation for reducing the concentration of the refrigerant. For example, the preset processing operation may include at least one of the following: stopping the refrigerant delivery, starting the exhaust function, and stopping the air supply function.

[0049] Among them, stopping the refrigerant delivery may include closing the shut-off valve of the refrigerant pipeline; starting the exhaust function may include opening the exhaust air valve; stopping the air supply function may include closing the air supply air valve.

[0050] In this way, for the air conditioner in the running state and the shutdown state, the refrigerant concentration is detected by sensors in different positions, so that the concentration can be flexibly detected for the different diffusion speeds of the refrigerant in the running state and the shutdown state, avoiding the failure to timely detect refrigerant leakage in different states through a single sensor detection, thereby improving the flexibility and accuracy of refrigerant detection and thus improving safety.

[0051] Since the air conditioner does not supply air or refrigerant when it is turned off, if the refrigerant leaks accidentally, it will spread very slowly, and it will be difficult to detect it in time if the sensor is far away. Figure 2 A flow chart of an air conditioning operation control method provided in this embodiment is shown as follows: Figure 2 As shown, step S10 may include:

[0052] S11: In response to the air conditioner being in the off state, controlling a fan in an indoor unit of the air conditioner to operate at a predetermined speed;

[0053] S12: Determine the refrigerant concentration by detecting the refrigerant concentration through 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 may also be referred to as an indoor unit, and the outdoor unit may also be referred to as an outdoor unit. The indoor unit is used to supply air to the room and exhaust air to the outside. The indoor unit may include an air outlet, the air outlet may be connected to the air supply outlet through an air supply pipeline, and connected to the air exhaust outlet through an exhaust pipeline. The air supply pipeline supplies air to the room through the air supply outlet, and the exhaust pipeline exhausts air to the outside through the exhaust outlet.

[0055] In one embodiment, the second sensor corresponding to the shutdown state can be set in the indoor unit, that is, inside the indoor unit, so as to avoid the situation where the refrigerant is difficult to diffuse inside the indoor unit when the indoor unit is not producing air, resulting in accumulation to a high concentration, which is still difficult to detect at the air outlet.

[0056] In one embodiment, the fan in the indoor unit can be an air supply fan used to blow air to supply or exhaust air through the air outlet in the operating state, or can also be a separately arranged circulation fan different from the air supply fan. The fan can be located on the side of the indoor unit where the air outlet is opened.

[0057] In one embodiment, the second sensor may be disposed 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 positions.

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

[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 has low energy consumption and allows the refrigerant to diffuse into the interior of the indoor unit faster.

[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 proportion of the operating speed, and the predetermined proportion may be 10%, 5% or 3%.

[0061] In this way, when the indoor unit is not running in the shutdown state, the diffusion of the refrigerant can be accelerated by slowly running the fan inside the indoor unit, and then the refrigerant concentration can be detected by the sensor inside the indoor unit. This can prevent the refrigerant from being difficult to diffuse in the indoor unit and continuing to accumulate to a high concentration while still being undetectable by the external sensor, thereby improving detection accuracy and safety.

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

[0063] In response to the air conditioner being in an operating state, it is determined that the refrigerant concentration is detected by a first sensor corresponding to the operating state; the first sensor is located at an air outlet of an indoor unit of the air conditioner.

[0064] In one embodiment, the first sensor corresponding to the operating state can be set at the air outlet, for example, the distance between the first sensor and the air outlet is less than a predetermined distance, etc. Thus, the refrigerant concentration in the air discharged from the indoor unit can be quickly detected, avoiding the inability to accurately detect the refrigerant inside the indoor unit due to the refrigerant being discharged with the wind.

[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 to detect the refrigerant concentration through the first sensor corresponding to the operation state, thereby avoiding the inability to accurately detect when the indoor unit is not working in the operation state.

[0066] In one embodiment, the above steps may include: in response to the air conditioner being in a running state, determining to detect the refrigerant concentration through a first sensor corresponding to the running state and a second sensor corresponding to the shutdown state. For example, in response to the air conditioner being in a running state and the wind speed of the air conditioner being lower than a predetermined wind speed, determining to detect the refrigerant concentration through a first sensor corresponding to the running state and a second sensor corresponding to the shutdown state. Therefore, for the case of a low wind speed, the internal and external sensors of the indoor unit can be used for simultaneous detection, thereby further improving the 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 may mean that the distance between the first sensor and the air outlet is less than a predetermined distance, wherein the predetermined distance may 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 in operation, the refrigerant concentration can be detected by the sensor at the air outlet, which can avoid the rapid diffusion of the refrigerant carried by the wind, making it difficult to detect the accurate concentration inside the indoor unit, thereby improving the accuracy of the detection.

[0069] When the refrigerant leakage reaches the dangerous threshold, the refrigerant concentration needs to be reduced as quickly as possible to reduce the amount of refrigerant in the room. Figure 3 A flow chart of an air conditioning operation control method provided in this embodiment is shown as follows: 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 controlled to be closed, and the supply air valve is closed and / or the exhaust air valve is opened.

[0071] In one embodiment, the refrigerant pipeline may be a pipeline connected to the indoor unit to transport the refrigerant to the indoor unit, and the shutoff valve may be a valve in the refrigerant pipeline that controls the on-off of the refrigerant pipeline. The shutoff valve of the refrigerant pipeline of the air conditioner is closed, that is, the refrigerant pipeline is controlled to be shut off, and the refrigerant stops entering the indoor unit.

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

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

[0074] Optionally, closing the air supply valve and / or opening the exhaust valve may also include: in response to being in an exhaust state, keeping the exhaust valve open or opening the exhaust valve to a maximum opening; and / or, in response to not being in an air supply state, keeping the supply valve closed.

[0075] In one embodiment, the step S21 may further include: outputting alarm information. For example, outputting alarm information may include outputting alarm information in at least one of light, sound, text, and other forms.

[0076] Here, the output alarm information can be output through a display screen, a speaker, other terminal devices connected to the air conditioning equipment, etc.

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

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

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

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

[0081] If the air conditioner is in the off state, the air conditioner indoor unit is started and the exhaust air valve is opened.

[0082] In one embodiment, when the air conditioner is in the off state, the indoor unit is not running, and the air supply and exhaust functions are not started. Therefore, starting the indoor unit of the air conditioner and opening the exhaust air valve may include: starting the indoor unit and opening the exhaust air valve, and keeping the air supply air valve closed.

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

[0084] In one embodiment, starting the air conditioner indoor unit and opening the exhaust valve may include: starting the air conditioner indoor unit and opening the exhaust valve, and continuously detecting the refrigerant concentration based on the first sensor. At this time, since the indoor unit has been started, the accuracy of continuing to detect 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 air valve may include: opening the exhaust air valve and setting the exhaust air speed to a predetermined wind speed. For example, the predetermined wind speed may be a maximum exhaust air speed, or a predetermined multiple of a working wind speed corresponding to the exhaust state.

[0086] In this way, when it is detected that the refrigerant concentration reaches the dangerous threshold, the air conditioner is awakened and starts working in time, and the refrigerant is discharged as soon as possible through the exhaust function to reduce the danger.

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

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

[0089] Here, the operating state or the shutdown state may refer to the operating state or the 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 executing the preset processing operation.

[0091] For example, when the operating state before the preset processing operation is a non-refrigeration state, restoring to the operating state before performing the preset processing operation may include: keeping the refrigerant pipeline shut-off valve closed.

[0092] For example, when the operating state before the preset processing operation is a cooling state, restoring to the operating state before the preset processing operation is performed may include: controlling the refrigerant pipeline shutoff valve to open. For example, controlling the refrigerant pipeline shutoff valve to open to the opening degree before the preset processing operation is performed.

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

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

[0095] In one embodiment, stopping the preset processing operation and restoring to the running state or the shutdown state may also 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 and restoring the rotation speed of the fan in the indoor unit to a predetermined speed, and / or closing the exhaust air valve.

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

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

[0099] The refrigerant pipeline shut-off valve of the air conditioner is controlled to open, and the air supply valve is opened and / or the exhaust valve is closed.

[0100] Here, controlling the refrigerant pipeline shutoff valve of the air conditioner to open may control the refrigerant pipeline shutoff valve to open to an opening degree before performing a preset processing operation.

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

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

[0103] In one embodiment, the method may further include: if the refrigerant concentration is continuously lower than a preset threshold value within a predetermined time period, detecting the refrigerant concentration by the first sensor, thereby reducing the energy consumption generated by the two sensors working simultaneously.

[0104] In this way, by restoring the original state of refrigerant delivery and air valves, they can be adjusted back to the original working state in time after the risk of refrigerant leakage is eliminated, avoiding affecting normal work or generating unnecessary energy consumption.

[0105] The embodiment of the present application also provides an air conditioner operation control system, the system comprising: a controller, a first sensor and a second sensor; wherein the first sensor and the second sensor are located at different positions in the air conditioner;

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

[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 aforementioned embodiments.

[0108] Here, the specific implementations of the air conditioner, the first sensor and the second sensor and the related embodiments of the controller executing the action can refer to the related contents in the aforementioned embodiments, which will not be repeated here.

[0109] An embodiment of the present application further provides an air conditioner, which includes the air conditioner operation control system described in the aforementioned embodiment, and / or the air conditioner applies the air conditioner operation control method described in any one or more of the aforementioned embodiments.

[0110] As a possible implementation, Figure 4As shown, in the figure, 1 is the exhaust air valve, 2 is the supply air valve, 3 is the supply air duct, 4 is the air conditioner indoor fan, 5 is the refrigerant detection sensor inside the indoor unit, i.e., the second sensor, 6 is the air conditioner indoor evaporator, 7 is the return air duct, and 8 is the refrigerant detection sensor at the air outlet, i.e., the first sensor. One end of the air outlet duct of the air conditioner indoor unit is connected to the outside for exhaust, and the other end is connected to the indoor for air supply. Both the exhaust and supply outlets are controlled by air valves. When the air conditioner indoor unit works normally, the air supply outlet is opened, the exhaust outlet is closed, and the air conditioner indoor unit provides cooling or heating to the room. When the refrigerant leaks, the refrigerant detection sensor detects that the refrigerant concentration reaches the critical value of combustion, and the risk of combustion or explosion is prone to occur. At this time, the air supply outlet is closed, the exhaust outlet is opened, and the air conditioner indoor unit is running to discharge the air mixed with refrigerant to the outside of the room to avoid accidents.

[0111] like Figure 5 The figure shows the workflow of refrigerant leakage detection. In an air-conditioning system using flammable refrigerants, when the indoor unit is in cooling, heating or air supply operation, if the indoor unit refrigerant leaks, the refrigerant sensor monitors. If the refrigerant concentration reaches the set threshold, the air-conditioning control system responds, first closing the outdoor unit refrigerant cut-off valve to prevent more refrigerant from entering the indoor unit and leaking. At the same time, the alarm device sounds an alarm, and the display panel issues a prompt to remind people in the room to ventilate. At the same time, the air supply valve is closed and the exhaust valve is opened to reduce the refrigerant concentration in the room. When the indoor unit is stopped, the refrigerant sensor inside the indoor unit monitors, and the indoor unit fan runs slowly, so as to ensure that the refrigerant at the leaking point can quickly diffuse to the refrigerant sensor. If the indoor unit refrigerant leaks, the refrigerant concentration reaches the set threshold, and the air-conditioning control system responds and performs a series of processing actions.

[0112] like Figure 6 As shown, the embodiment of the present application provides an air conditioning operation control device, which may include:
