[0042] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0043] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0044] First, an application scenario involved in an embodiment of the present application is described.

[0045] In air conditioners, refrigerant is usually used to transfer heat energy to produce a cooling effect. As a cooling medium, the refrigerant is compressed from a gaseous state into a high-temperature and high-pressure gas through a compressor and transported to a condenser for cooling. After cooling, it becomes a medium-temperature and high-pressure liquid refrigerant. The medium-temperature liquid refrigerant is throttled and reduced in pressure by an expansion valve to become a low-temperature and low-pressure liquid. It absorbs heat from the air through an evaporator and vaporizes into a gas. It then returns to the compressor to continue compression, and the cycle is used for refrigeration.

[0046] At present, the common refrigerants in air conditioners are R22 refrigerant, R32 refrigerant, R410A refrigerant, R125 refrigerant, etc. R22 refrigerant is the most widely used medium and low temperature refrigerant today, and is used in a variety of refrigeration equipment. However, R22 refrigerant will damage the ozone layer, so its use is gradually decreasing; R32 refrigerant will not damage the ozone layer, is environmentally friendly, and has good refrigeration performance, but R32 refrigerant is flammable, and once leaked, it may cause danger; R125 refrigerant will not damage the ozone layer and is not flammable. It can be mixed with R32 refrigerant to obtain R140A refrigerant; R140A refrigerant is also a new type of environmentally friendly refrigerant with a working pressure of about 1.6 times that of ordinary R22 refrigerant air conditioners, and has a higher heating or cooling effect. R410A is mainly composed of hydrogen, fluorine and carbon elements, and has the characteristics of stability, non-toxicity and superior performance. At the same time, it does not contain chlorine, does not react with ozone, will not damage the ozone layer and is not flammable.

[0047] R32 refrigerant is a flammable refrigerant that is slightly toxic and explosive. If the refrigerant leaks and the accumulated concentration is too high, it may form an explosive mixture, causing an accident and threatening human health, so a safe refrigerant leakage treatment method is needed.

[0048] like Figure 1As shown, the embodiment of the present application proposes a refrigerant processing device for an air conditioner, which is used to make the combustible refrigerant in the air conditioner non-flammable after processing. The refrigerant processing device includes a mixing tank 11 installed in the indoor unit of the air conditioner, a sensor 12, a first pipeline control device 21, a refrigerant transmission pipeline 13 and a first refrigerant; the sensor 12 is installed in the indoor unit of the air conditioner, the mixing tank 11 is connected to the refrigerant transmission pipeline 13 of the indoor unit of the air conditioner, and the first pipeline control device 21 is installed at the connection between the inlet of the mixing tank 11 and the refrigerant transmission pipeline 13, and the first refrigerant is transported through the refrigerant transmission pipeline 13; the sensor 12 is used to detect the concentration of the first refrigerant around the indoor unit of the air conditioner; when the first refrigerant around the indoor unit of the air conditioner is When the concentration reaches a preset value, the first refrigerant is controlled to flow from the refrigerant transmission pipeline 13 into the mixing tank 11; the first pipeline control device 21 divides the refrigerant transmission pipeline 13 into an inlet end and an outlet end, and the first pipeline control device 21 is in a DC gear by default, and the DC gear controls the inlet end and the outlet end to be connected. The first pipeline control device 21 is also provided with a mixing gear; the mixing gear is used to control the refrigerant transmission pipeline 13 to be connected with the inlet of the mixing tank 11; a mixture is provided in the mixing tank 11; the mixture is used to mix with the first refrigerant to obtain a second refrigerant that is non-flammable; the first pipeline control device 21 is used to switch the DC gear to the mixing gear when the concentration of the first refrigerant reaches a preset condition.

[0049] In the embodiment of the present application, the concentration of the first refrigerant around the air conditioner is detected by the sensor 12 installed in the air conditioner indoor unit in order to prevent the first refrigerant from leaking on the air conditioner indoor unit side. When the first refrigerant leaks on the air conditioner indoor unit side, the first refrigerant may leak all into a certain room. The first refrigerant is flammable, and when the concentration of the first refrigerant accumulated in the room is too high, it may be dangerous. By detecting the concentration of the first refrigerant around the air conditioner indoor unit, it is possible to quickly identify the leakage of the first refrigerant in the indoor space and reduce the danger caused by the leakage of the first refrigerant.

[0050] In some embodiments, R32 refrigerant is used as the first refrigerant. R32 refrigerant is environmentally friendly and cost-effective, but the safety level of R32 refrigerant is A2L, that is, it is a refrigerant with low toxicity and low flammability, and it may explode when encountering open flames when the concentration is 14.4%-29.3%.

[0051] It should be noted that when the first refrigerant concentration around the air conditioner indoor unit reaches a preset value, the first refrigerant is controlled to flow from the refrigerant transmission pipeline 13 into the mixing tank 11, wherein the preset value of the first refrigerant concentration around the air conditioner indoor unit is detected to be 6%.

[0052] It should be noted that the first pipeline control device 21 is in the DC gear by default, and the DC gear controls the connection between the inlet and the outlet. The first pipeline control device 21 is also provided with a mixed gear; the mixed gear is used to control the connection between the refrigerant transmission pipeline 13 and the inlet of the mixing tank 11. For the first pipeline control device 21, the mixed gear of the first pipeline control device 21 is the gear in which the inlet end is connected to the inlet of the mixing tank 11, such as Figure 2 As shown, when the first pipeline control device 21 is in the DC gear, the first refrigerant transmission direction is shown by the arrow. Figure 3 As shown, when the first pipeline control device 21 is in the mixed gear, the first refrigerant transmission direction is shown by the arrow.

[0053] In some embodiments, Figure 2 As shown, a three-way valve is used as the first pipeline control device 21, and the connection mode between the refrigerant transmission pipeline 13 and the mixing tank 11 is controlled by controlling the position of the valve core inside the three-way valve.

[0054] In some embodiments, the mixture provided in the mixing tank 11 can be a flame retardant, so that the first refrigerant and the flame retardant are mixed, so that the first refrigerant is not flammable to avoid the risk of explosion. For example, a bromine-based flame retardant can be built into the mixing tank 11, and the bromine-based flame retardant is a mixture of one or more of decabromodiphenylethane, brominated epoxy resin and brominated polystyrene. When the bromine-based flame retardant is heated, it decomposes to produce flame-retardant hydrogen bromide gas to dilute the concentration of oxygen and the first refrigerant, and the hydrogen bromide gas can capture the core free radicals in the combustion chain reaction, generate bromine free radicals with lower Mars, thereby aligning or terminating the occurrence of the chain reaction, and achieving the purpose of flame retardancy. Therefore, the bromine-based flame retardant and the first refrigerant can be mixed to make the mixed refrigerant have the characteristics of reducing flammability. The mixture in the mixing tank 11 can also use other types of flame retardants, and this application is not limited here.

[0055] In the embodiment of the present application, the first refrigerant concentration around the indoor unit of the air conditioner is detected by the sensor 12; when the first refrigerant concentration around the indoor unit of the air conditioner reaches a preset value, the first refrigerant is controlled to flow from the refrigerant transmission pipeline 13 into the mixing tank 11; the first pipeline control device 21 divides the refrigerant transmission pipeline 13 into an inlet end and an outlet end, and the first pipeline control device 21 is in a DC gear by default, and the DC gear controls the inlet end and the outflow end to be connected, and the first pipeline control device 21 is also provided with a mixed gear; the mixed gear is used to control the refrigerant transmission pipeline 13 to be connected with the inlet of the mixing tank 11; a mixture is provided in the mixing tank 11; the mixture is used to mix with the first refrigerant to obtain a second refrigerant that is non-flammable; the first pipeline control device 21 is used to switch the DC gear to the mixed gear when the first refrigerant concentration reaches a preset condition. The present application switches the first pipeline control device 21 to allow the first refrigerant to flow into the mixing tank 11 when a leakage of the first refrigerant is detected, thereby preventing the first refrigerant from continuing to circulate and then leaking. A mixture is provided in the mixing tank 11, so that the first refrigerant and the mixture are mixed to obtain a second refrigerant that is not flammable, thereby reducing the risk of refrigerant ignition and reducing the danger of refrigerant leakage when the refrigerant leaks.

[0056] An embodiment, such as Figure 2 As shown, a second pipeline control device 22 is provided at the connection between the outlet of the mixing tank 11 and the refrigerant transmission pipeline 13, and the second pipeline control device 22 has a DC gear and a mixed gear; when the air-conditioning indoor unit is in working state and the first refrigerant concentration around the air-conditioning indoor unit reaches a preset value, the second pipeline control device 22 switches to the mixed gear; when the air-conditioning indoor unit is in standby state and the first refrigerant concentration around the air-conditioning indoor unit reaches a preset value, the second pipeline control device 22 maintains the DC gear.

[0057] In some embodiments, a three-way valve can also be used as the second pipeline control device 22. The second pipeline control device 22 also divides the refrigerant transmission pipeline 13 into an inlet end and an outlet end. The second pipeline control device 22 has a DC gear and a mixed gear, wherein the DC gear is a gear in which the inlet end and the outlet end are connected, and the mixed gear is a gear in which the outlet end is connected to the outlet of the mixing tank 11.

[0058] In the embodiment of the present application, the gear position of the second pipeline control device 22 is adjusted by detecting the state of the air conditioner indoor unit, such as Figure 3As shown, when it is detected that the concentration of the first refrigerant around the air-conditioning indoor unit reaches a preset value, it indicates that the first refrigerant has leaked on the air-conditioning indoor unit side. At this time, the state of the air-conditioning indoor unit is detected. If the air-conditioning indoor unit is in working state, the second pipeline control device 22 is switched to the mixing gear. At this time, the first pipeline control device 21 and the second pipeline control device 22 are both in the mixing gear, so that the first refrigerant enters the mixing tank 11 from the refrigerant transport pipeline through the first pipeline control device 21, and the second refrigerant is obtained after mixing in the mixing tank 11, and the second refrigerant is made to flow out to the refrigerant transport pipeline through the second pipeline control device 22; Figure 4 As shown, if the indoor unit of the air conditioner is in standby mode, the second pipeline control device 22 is kept in the DC gear. At this time, the first pipeline control device 21 is in the mixing gear. The first refrigerant enters the mixing tank 11 from the refrigerant transport pipeline through the first pipeline control device 21, and the second refrigerant is obtained after mixing in the mixing tank 11. Since the second pipeline control device 22 is in the DC gear, the outlet of the mixing tank 11 is in a closed state, so that the mixed second refrigerant is stored in the mixing tank 11.

[0059] It should be noted that when the air conditioner indoor unit is in working state, the mixed second refrigerant flows into the refrigerant transport pipeline to participate in the work, which ensures the working effect of the air conditioner to a certain extent. At the same time, since the second refrigerant is not flammable, emptying the second refrigerant will not cause danger.

[0060] In some embodiments, when it is detected that the air conditioner indoor unit is in working state, the second pipeline control device 22 is switched to the mixing gear and the air conditioner outdoor unit is stopped, so that the refrigerant flow rate flowing into the mixing tank 11 is reduced, which is conducive to the full mixing of the first refrigerant and the mixture.

[0061] An embodiment, such as Figure 2 As shown, the mixing tank 11 includes a piston plate 23, a mixture channel 24 and a one-way valve 25; the piston plate 23 is clamped in the mixing tank 11, the inlet and outlet of the mixing tank 11 are arranged on the same side of the piston plate 23, the side of the piston plate 23 away from the inlet and outlet is filled with the mixture, the two ends of the mixture channel 24 are connected to the two sides of the piston plate 23, and the one-way valve 25 is arranged on the mixture channel 24; the one-way valve 25 is used to control the flow direction of the mixture, so that the mixture in the mixing tank 11 flows to the side of the piston plate 23 with the inlet and outlet.

[0062] In the embodiment of the present application, a piston plate 23 is provided in the mixing tank 11, and a side of the piston plate 23 away from the inlet and outlet is filled with a mixture. When the first refrigerant enters from the inlet of the mixing tank 11, due to the effect of gravity, the first refrigerant is forced to squeeze the piston plate 23 to reduce the storage space of the mixture. The mixture enters the side with the first refrigerant through the mixture channel 24 and mixes with the first refrigerant to form a second refrigerant. Affected by the mass of the first refrigerant entering the mixing tank 11, the piston plate 23 squeezes the corresponding space and determines the mass of the mixture involved in the mixing according to the mass of the first refrigerant entering the mixing tank 11, thereby keeping the mixing ratio of the first refrigerant and the mixture balanced.

[0063] It should be noted that a one-way valve 25 is also provided on the mixture channel 24, through which the mixture can only flow to the first refrigerant side, so that the first refrigerant or the mixed second refrigerant cannot flow back to the mixture side, thereby promoting the mixing process to continue.

[0064] In some embodiments, Figure 2 As shown, the mixing tank 11 has a mixture built in it, without a piston plate 23, a mixture channel 24 and a one-way valve 25. When the first pipeline control device 21 is switched to the mixing gear, the first refrigerant enters the mixing pipe from the refrigerant transmission pipeline 13 to be mixed to form the second refrigerant, thereby reducing the preparation process required for the mixing tank 11.

[0065] In one embodiment, the first refrigerant is R32 refrigerant, the mixed agent is R125 refrigerant, and the second refrigerant obtained after mixing is R410A refrigerant.

[0066] In the embodiment of the present application, R32 refrigerant is used as the first refrigerant. R32 refrigerant has good environmental protection performance and high refrigeration efficiency. R125 refrigerant is used as the mixing agent. R125 refrigerant does not damage the ozone layer and can form R410A refrigerant after mixing with R32 refrigerant. R410A refrigerant is efficient, stable, non-toxic and non-flammable, so that the R410A refrigerant formed after the mixture can complete the work normally while not being flammable, reducing the risk of refrigerant leakage. When leakage occurs, R410A refrigerant is non-toxic and harmless and can be completely discharged without causing harm to users, thereby maximizing the safety of refrigerant leakage.

[0067] In one embodiment, the volume ratio of the first refrigerant to the mixed agent is 1:1.3.

[0068] In the embodiment of the present application, in order to ensure the mixing effect, the mixture in the mixing tank 11 needs to be sufficient, and the volume of the mixture is 1.3 times that of the first refrigerant, so that the first refrigerant has enough mixture to be mixed, and the situation where the mixture is consumed and the first refrigerant still remains will not occur. In this way, it is ensured that the first refrigerant can be mixed to obtain the non-flammable second refrigerant, thereby improving safety in the event of refrigerant leakage.

[0069] In one embodiment, R410A is used because it is stable, non-toxic and non-flammable, and R410A refrigerant is obtained by mixing R32 refrigerant and R125 refrigerant in a mass ratio of 1:1. The density of R125 refrigerant is 1.245 g / cm3 and the density of R32 refrigerant is 0.958 g / cm3. When R32 refrigerant is used as the first refrigerant and R125 refrigerant is used as the mixed agent, the volume of R125 refrigerant required is 1.3 times that of R32 refrigerant. Therefore, the volume of R125 refrigerant stored in the mixing tank 11 is 1.3 times that of R32 refrigerant.

[0070] In one embodiment, an electronic expansion valve 14 is provided on the refrigerant transmission pipeline 13 at the inflow end of the first pipeline control device 21 .

[0071] In the embodiments of the present application, Figure 1 As shown, by setting an electronic expansion valve 14 at the inflow end of the first pipeline control device 21, the liquid supply amount of the first refrigerant in the refrigerant transmission pipeline 13 is adjusted. The electronic expansion valve 14 is a throttling element in the refrigeration system, which controls the voltage or current on the expansion valve through an electrical signal to adjust the liquid supply amount. When the sensor 12 detects that the concentration of the first refrigerant around the air conditioner indoor unit reaches a preset condition, the electronic expansion valve 14 is controlled to reduce the liquid supply amount of the first refrigerant, thereby slowing down the leakage speed of the refrigerant, and at the same time allowing the first refrigerant entering the mixing tank 11 to be fully mixed.

[0072] Figure 5 is a flowchart of a method for handling a flammable refrigerant leak provided in an embodiment of the present application, such as Figure 5 As shown, the method may include:

[0073] Step 101, detecting the first refrigerant concentration around the indoor unit of the air conditioner, when the first refrigerant concentration reaches a preset condition, triggering a refrigerant leakage alarm, and turning on the indoor fan of the indoor unit of the air conditioner.

[0074] In the embodiment of the present application, the first refrigerant is flammable. When the first refrigerant accumulates to a certain concentration, it is easy to explode when encountering an open flame. By detecting the concentration of the first refrigerant around the air-conditioning indoor unit, it is determined whether the first refrigerant has leaked. When the concentration of the first refrigerant reaches a preset condition, a refrigerant leakage alarm is triggered. The preset condition is that the detected concentration of the first refrigerant reaches 6%. When the refrigerant leakage alarm is triggered, the internal fan of the air-conditioning indoor unit is turned on to dilute the concentration of the first refrigerant and reduce the probability of danger.

[0075] For example, the first refrigerant is prone to explosion when the concentration is 14.4%-29.3%. By detecting the refrigerant leakage alarm, the air conditioner fan is turned on to allow air to flow in to dilute the first refrigerant concentration, reducing the first refrigerant concentration to less than 14.4%. At this time, even if the first refrigerant leaks, it will not cause danger, thereby improving safety in the event of a refrigerant leak.

[0076] Step 102, controlling the first refrigerant to enter the mixing tank and mix with the mixed agent to obtain the second refrigerant to be discharged.

[0077] In an embodiment of the present application, a second refrigerant is obtained by allowing a first refrigerant to enter a mixing tank and mix with a mixing agent, wherein the mixing agent used to mix with the first refrigerant can effectively reduce the flammability of the first refrigerant, so that the mixed second refrigerant has a non-flammable property.

[0078] For example, when R32 refrigerant is used as the first refrigerant, R32 refrigerant is flammable. Using a mixing agent can make R32 refrigerant non-flammable. Bromine-based flame retardants can be mixed with R32 refrigerant to reduce the flammability of R32 refrigerant, or R125 refrigerant can be used as a mixing agent and mixed with R32 refrigerant to generate R410A refrigerant. R410A refrigerant is non-flammable and non-toxic, and can also maintain the normal operation of the refrigerant to a certain extent.

[0079] Optionally, the method further includes:

[0080] Step 103 , detecting the working state of the air conditioner, and when the air conditioner is in standby state and the refrigerant leakage alarm continues to alarm for more than a preset time, controlling the first refrigerant to enter the mixing tank.

[0081] In the embodiment of the present application, the working state of the air conditioner is detected, and the working state of the air conditioner is divided into working state and standby state, and corresponding measures are taken for different states. When the air conditioner is in working state, the continuous alarm time of the refrigerant leakage alarm is detected, and when the continuous alarm time exceeds the preset time, the first refrigerant is controlled to enter the mixing tank. By continuously alarming for the preset time, the risk of false alarms can be reduced, making the refrigerant leakage alarm more accurate, and at the same time, the timeliness of taking corresponding measures after the alarm is triggered can be maximized.

[0082] In one embodiment, the preset time that the refrigerant leakage alarm lasts for is set to 1 minute. When the alarm lasts for more than 1 minute, corresponding measures for the refrigerant leakage are taken.

[0083] Step 104: Control the outlet of the mixing tank to remain in a closed state.

[0084] In an embodiment of the present application, when it is detected that the air conditioner is in standby mode, the first refrigerant is allowed to enter from the mixing tank inlet, while the mixing tank outlet is kept closed, so that the mixed second refrigerant is stored in the mixing tank, and the refrigerant of the air conditioner in standby mode is stored in the mixing tank, thereby reducing the leakage of the refrigerant and reducing the economic loss of the user.

[0085] Optionally, the method further includes:

[0086] Step 105: When the mixing is completed, the inlet and outlet of the mixing tank are controlled to be in a closed state.

[0087] In the embodiment of the present application, after the first refrigerant is mixed with the mixture in the mixing tank and the mixing is completed, the inlet and outlet of the mixing tank are controlled to be in a closed state. At this time, the refrigerant transmission pipeline does not pass through the mixing tank, but passes by the mixing tank, and the second refrigerant generated after mixing is sealed in the mixing tank. In this way, the refrigerant in the air conditioner can be preserved as much as possible in the standby state of the air conditioner, reducing the economic loss of the user.

[0088] Step 106: When the refrigerant leakage alarm is still sounding, enter the step of detecting the working status of the air conditioner.

[0089] In an embodiment of the present application, when the refrigerant leakage alarm is still sounding, the step of detecting the working state of the air conditioner is entered. When it is detected that the working state of the air conditioner is in the standby state and the refrigerant leakage alarm continues to sound for more than a preset time, the first refrigerant is controlled to enter the mixing tank. When the leaking point is still leaking refrigerant, the mixing tank can be opened again, the first refrigerant flows in and is mixed to obtain the second refrigerant. When the leaking point continues to leak, the mixed second refrigerant is finally stored in the mixing tank. Continuously repeating the steps of detecting leakage and opening the mixing tank can deal with the situation where the leaking point in the air conditioner continues to slowly leak refrigerant. In reality, the probability of this happening is the highest. By continuously detecting and taking corresponding measures, remedial measures can be taken in time when leakage still occurs, so as to maximize the safety of refrigerant leakage.

[0090] Optionally, the method further includes:

[0091] Step 107, detecting the working state of the air conditioner. When the air conditioner is in working state, controlling the outlet of the mixing tank to be in an open state.

[0092] In the embodiment of the present application, when the air conditioner is detected to be in the working state, the outlet and inlet of the mixing tank are controlled to be in the open state, at which time the first refrigerant enters the mixing tank from the refrigerant transmission pipeline, and the second refrigerant obtained after mixing enters the refrigerant transmission pipeline from the mixing tank outlet to complete the temperature control of the air conditioner. By adjusting the inlet and outlet of the mixing tank to the open state, when the air conditioner uses the first refrigerant for the working cycle, the first refrigerant circulating in the mixing tank is mixed to form a second refrigerant that is not flammable. Therefore, when the air conditioner is in the working state, the normal operation of the air conditioner is maintained, and at the same time, the flammable first refrigerant is converted into a non-flammable second refrigerant. Even if the second refrigerant leaks, it will not cause a safety threat to the user, thereby improving the safety of refrigerant leakage.

[0093] Step 108: When the mixing is completed, the inlet and outlet of the mixing tank are controlled to be in a closed state.

[0094] In an embodiment of the present application, when the air conditioner is in working condition and enters the mixing completion state, the inlet and outlet of the mixing tank are closed. At this time, the refrigerant circulating in the refrigerant transmission pipeline is the second refrigerant which is non-flammable. The second refrigerant participates in the normal operation of the air conditioner. At the same time, when leakage occurs, since the second refrigerant is non-flammable, it will not cause a safety threat to the user.

[0095] In one embodiment, when the inlet and outlet of the mixing tank are in a closed state, the one-way valve on the mixing agent channel of the mixing tank is closed, and when the inlet of the mixing tank is in an open state, the one-way valve is opened, thereby reducing the power consumption of the one-way valve.

[0096] Optionally, before step 105 or step 108, the method further includes:

[0097] Step 109: Obtain the concentration of the leaked first refrigerant, and obtain a preset mixing time according to the concentration of the leaked first refrigerant.

[0098] In the embodiment of the present application, the mixing time is controlled according to the leakage concentration of the first refrigerant. When the leakage concentration of the first refrigerant is high, the opening time of the mixing tank inlet is increased, so that the mixing time of the first refrigerant and the mixture is increased, thereby increasing the mixing effect.

[0099] In some embodiments, Figure 6 As shown, when R32 refrigerant is used as the first refrigerant and R125 refrigerant is used as the mixed agent, the leakage concentration of R32 refrigerant and the opening time of the mixing tank inlet are shown in the figure. When the leakage concentration of R32 refrigerant is less than 6%, the mixing tank inlet does not need to be opened. When the leakage concentration of R32 refrigerant reaches 90%, the mixing tank inlet is opened for 124 minutes.

[0100] Step 110: When the inlet opening time of the mixing tank reaches the mixing time, the mixing is completed.

[0101] In an embodiment of the present application, the opening time of the mixing tank inlet is determined according to the concentration of the leaked first refrigerant. When the leakage concentration is high, the required mixing time is longer, and when the leakage concentration is low, the required mixing time is shorter. After the opening time of the mixing tank inlet reaches the required mixing time, the mixing is completed. The conditions for entering the mixing completed state are dynamically and flexibly controlled, so that appropriate remedial measures can be taken when encountering a variety of different leakage situations, thereby reducing the risk of refrigerant leakage.

[0102] In the embodiment of the present application, the first refrigerant concentration around the air conditioner is detected. When the first refrigerant concentration reaches a preset condition, the refrigerant leakage alarm is triggered, and the internal fan of the air conditioner is turned on; the internal fan is used to dilute the first refrigerant concentration; the first refrigerant is controlled to enter the mixing tank and mix with the mixture to obtain the second refrigerant to be discharged, wherein the second refrigerant is a non-flammable refrigerant. The working state of the air conditioner is detected. When the air conditioner is in standby state and the refrigerant leakage alarm continues to alarm for more than a preset time, the first refrigerant is controlled to enter the mixing tank, and the outlet of the mixing tank is controlled to remain in a closed state. After entering the mixing completion state, the inlet and outlet of the mixing tank are controlled to be in a closed state; when the refrigerant leakage alarm is still alarming, the step of detecting the working state of the air conditioner is entered. When the air conditioner is in the working state, the outlet of the mixing tank is controlled to be in an open state; when entering the mixing completion state, the inlet and outlet of the mixing tank are controlled to be in a closed state; the concentration of the leaked first refrigerant is obtained, and the preset mixing time is obtained according to the concentration of the leaked first refrigerant; when the opening time of the inlet of the mixing tank reaches the mixing time, the mixing completion state is entered. The present application triggers a refrigerant leakage alarm and turns on the internal fan of the air-conditioning indoor unit when a leakage of the first refrigerant is detected, thereby diluting the concentration of the first refrigerant around the indoor unit of the air-conditioning and reducing the risk of leakage of the first refrigerant; then controls the first refrigerant to enter a mixing tank and mix with a mixed agent to obtain a non-flammable second refrigerant, and when the air conditioner is in working condition, uses the non-flammable second refrigerant to maintain the normal operation of the air conditioner. At this time, even if the second refrigerant leaks, it will not pose a safety threat to the user because it is non-flammable; when the air conditioner is detected to be in standby mode, the mixed second refrigerant is sealed in the mixing tank to prevent the continuous leakage of the second refrigerant from causing losses to the user, and at the same time, the time for mixing to be completed is determined according to the concentration of the leaked first refrigerant, so that there is an adaptive mixing time for a variety of different leakage situations, reducing the possibility of danger caused by special leakage situations.
