[0052] The terms "include" and "contain" indicate the presence of the described features, whole, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, whole, steps, operations, elements, components and / or sets thereof.

[0053] Figure 1 is a flowchart of the air conditioner control method based on the shared outdoor unit provided by the present application. As shown in Figure 1 The air conditioner control method based on the shared outdoor unit provided by the embodiment of the present application is applied to an air conditioner, which comprises the following steps: in step 101, when it is determined that the cooking utensil is turned on and at least one human individual exists in the target indoor space determined by the radar module, the air conditioner indoor unit and the air conditioner outdoor unit are controlled to exchange heat in the cooling mode.

[0054] Among them, the target indoor space is the indoor space shared by the air conditioner indoor unit and the range hood.

[0055] It should be noted that the execution subject of the air conditioner control method based on the shared outdoor unit is an air conditioner control device based on the shared outdoor unit, which can be arranged in the air conditioner.

[0056] The application scenario of the air conditioner control method based on the shared outdoor unit of the embodiment of the present application is that the air conditioner shares the outdoor unit with the range hood provided with a heat exchanger in the air duct. Once the human body is sensed by the radar module on the indoor unit, the air conditioner is activated, and the refrigerant transmission mode between the air conditioner and the heat exchanger of the range hood is adjusted accordingly.

[0057] Among them, the air conditioner and the range hood are connected in communication by the same local area network. For a split type air conditioner, the indoor space where the air conditioner indoor unit and the range hood are located is taken as the target indoor space, so that the behavior of the human individual in the space is monitored by the radar module arranged on the air conditioner indoor unit, and the air conditioner and the range hood are controlled together.

[0058] For example, the target indoor space where the range hood and the air conditioner indoor unit are located can be a kitchen. When a human individual cooks, a large amount of heat and oil fume is generated in the kitchen, and thus the air conditioner needs to be started to reduce the apparent temperature, and the range hood needs to be started to remove the generated oil fume.

[0059] It should be noted that before step 101, since a large amount of heat is generated in the kitchen during cooking, the user demand is usually refrigeration, and thus an activation instruction needs to be sent to the air conditioner through a transmission medium to activate the refrigeration mode of the air conditioner in the target indoor space.

[0060] Optionally, the user can transmit the activation instruction through a wireless communication manner between the control device and the air conditioner by using the control device, so as to initialize the refrigeration mode of the entire air conditioner and start the radar module arranged on the air conditioner indoor unit.

[0061] Optionally, the user can issue the activation instruction in a voice interaction manner. After receiving the activation instruction and performing voice recognition, the air conditioner initializes and starts the air conditioner indoor unit and the radar module arranged thereon.

[0062] Specifically, in step 101, the air conditioner control device based on the shared outdoor unit receives the activation instruction sent by the user through the transmission medium, first makes the air conditioner indoor unit in a standby state, and then uses the radar module arranged on the air conditioner indoor unit to calculate and analyze the electromagnetic waves reflected by the human body in the target indoor space, and determines whether there is a human individual in the space through the current position of all human individuals analyzed.

[0063] If it is determined that the stove in the target space has been started and there is at least one human individual in the target indoor space, it means that the human individual is currently staying in the target indoor space for cooking and intends to adjust and reduce the indoor temperature by activating the refrigeration mode of the air conditioner. The air conditioner indoor unit and the air conditioner outdoor unit in the air conditioner are started to perform heat exchange in the refrigeration mode.

[0064] On the contrary, if it is determined that the stove in the target space has been started, but there is no human individual in the target indoor space, it means that the human individual may have forgotten to turn off the stove after completing cooking in the target indoor space, or the human individual may have temporarily left during a long cooking process. At this time, the intention is not clear, and the air conditioner needs to be controlled to continue to remain in the standby state, and whether the air conditioner outdoor unit exchanges heat with the range hood needs to be further determined in combination with the working condition of the range hood.

[0065] If it is determined that the stove in the target space has not been started and there is no human individual in the target indoor space, it means that the human individual is not cooking in the target indoor space, and the activated refrigeration mode of the air conditioner can be a misoperation. The air conditioner needs to be controlled to continue to remain in the standby state, and does not provide heat exchange to any of the air conditioner indoor unit and the range hood.

[0066] In the embodiment, the type and number of radar sensing devices in the radar module are not limited.

[0067] For example, the radar module can include a laser radar, an infrared sensor, etc.

[0068] Optionally, the millimeter wave radar has a horizontal detection range of ±75°, a vertical detection range of ±40°, a maximum detection distance of 8 meters, a distance output accuracy of 0.1 meters, an angle output accuracy of 1°, and does not involve privacy issues and is not affected by light. In addition, the response speed is relatively fast.

[0069] Therefore, the air conditioner control device based on the shared outdoor unit collects human individual contour information and / or human individual sign information in the indoor space where the corresponding indoor unit is located in real time based on the millimeter wave radar to sense whether a human individual exists in the indoor space.

[0070] For example, the radar module can include multiple types of sensing elements such as a millimeter wave radar, a laser radar, and an infrared sensor. The air conditioner control device based on the shared outdoor unit integrates the human individual contour information and / or human individual sign information collected by the sensing elements to comprehensively sense whether a human individual exists in the indoor space where the air conditioner is located.

[0071] In step 102, when it is determined that the range hood is started, the air conditioner outdoor unit is controlled to exchange heat with the air conditioner indoor unit and the range hood in parallel, so that the air conditioner outdoor unit supplies the range hood with cooling for the sucked oil fume and dirty air on the basis of continuously supplying the air conditioner indoor unit with cooling.

[0072] The range hood is provided with a heat exchanger in the exhaust duct to circulate the refrigerant between the range hood and the air conditioner outdoor unit.

[0073] Specifically, in step 102, the air conditioner control device based on the shared outdoor unit analyzes the working conditions of the air conditioner and the range hood.

[0074] If it is determined that the air conditioner has executed the cooling mode and the range hood is in the working state, a parallel branch is opened for the process of transmitting the condensed heat from the air conditioner outdoor unit to the air conditioner indoor unit in the cooling cycle of the air conditioner outdoor unit and the air conditioner indoor unit, so that part of the refrigerant flowing out of the air conditioner outdoor unit directly flows to the air conditioner indoor unit for evaporation and heat absorption, and the other part of the refrigerant flows to the heat exchanger in the range hood for evaporation and heat absorption. In this way, the air conditioner outdoor unit supplies the air conditioner indoor unit with cooling, and at the same time, the range hood cools the sucked oil fume and dirty air by using the low-temperature and low-pressure liquid refrigerant carried by the heat exchanger in the air duct during the process of discharging the oil fume and dirty air through the exhaust duct.

[0075] The process of the refrigeration cycle of any of the devices is that the refrigerant first becomes high-pressure gas through the compressor in the air conditioner outdoor unit, then is condensed to become high-pressure liquid through the heat exchanger of the air conditioner outdoor unit (which functions as a condenser at this time), then the high-pressure liquid is throttled through the refrigerant transmission path to become low-temperature and low-pressure liquid, then is evaporated to absorb heat through the heat exchanger of the air conditioner indoor unit or the range hood (which functions as an evaporator at this time), at the same time, the air in the space is cooled to achieve the purpose of reducing the temperature of the space, and becomes low-temperature and low-pressure gas into the compressor for the next refrigeration cycle.

[0076] Conversely, if any of the working conditions of the air conditioner and the working conditions of the range hood does not meet the above requirements, the air conditioner outdoor unit is not used to simultaneously exchange heat with the air conditioner indoor unit and the range hood.

[0077] When the radar module arranged by the indoor unit senses that a human individual in the target indoor space uses the stove for cooking, the embodiment of the present application decides to start the cooling mode of the air conditioner, and at the same time, opens a parallel transmission branch for the heat exchanger of the range hood in the circuit flowing from the condensation heat release of the air conditioner outdoor unit to the air conditioner indoor unit, so that the heat exchangers of the air conditioner indoor unit and the range hood can both evaporate and absorb heat. Based on the sensing of the distribution of human individuals in the indoor space, the refrigerant transmission mode can be cooperatively controlled in combination with the real-time working conditions of the air conditioner and the range hood, so that the heat exchange amount output by the outdoor unit as a condenser can be partially or entirely applied to the range hood for cooling interception, improving the oil fume separation effect, reducing the pollution of oil fume to the atmospheric environment, and optimizing the control performance and user experience of the air conditioner.

[0078] On the basis of any of the above embodiments, the control of the air conditioner outdoor unit to exchange heat with the parallel air conditioner indoor unit and range hood respectively to make the air conditioner outdoor unit supply the range hood with cooling for the inhaled oil fume pollution wind on the basis of continuously supplying the air conditioner indoor unit with cooling in the case that the range hood is determined to be started, comprises: in the case that the air conditioner is determined to be in the cooling mode and the range hood is determined to be in the running state, adjusting the operating frequency of the air conditioner outdoor unit to the rated value, and then opening the first refrigerant transmission path and the second refrigerant transmission path through the refrigerant reversing valve.

[0079] The air conditioner outdoor unit is communicated with the range hood and / or the air conditioner indoor unit through a refrigerant reversing valve. The first refrigerant transmission path is used for communicating the refrigerant transmission between the air conditioner indoor unit and the air conditioner outdoor unit. The second refrigerant transmission path is used for communicating the refrigerant transmission between the air conditioner indoor unit and the range hood.

[0080] It should be noted that the air conditioner and the range hood are connected through a refrigerant reversing valve, in addition to the ports connected with the refrigerant input pipeline and the refrigerant output pipeline of the air conditioner outdoor unit and the refrigerant input pipeline and the refrigerant output pipeline of the air conditioner indoor unit, the refrigerant reversing valve also starts a port connected with the refrigerant input pipeline and the refrigerant output pipeline of the heat exchanger in the range hood, to form a closed path about the parallel arrangement of the range hood and the air conditioner.

[0081] Specifically, in step 102, based on the air conditioner control device sharing the outdoor unit, if it is determined that the range hood has also executed the corresponding working mode during the continuous refrigeration process of the air conditioner, the operating frequency of the air conditioner outdoor unit is adjusted to the rated maximum value, and then the refrigerant reversing valve is controlled to open the ports connected with the refrigerant input pipeline and the refrigerant output pipeline of the air conditioner outdoor unit and the refrigerant input pipeline and the refrigerant output pipeline of the air conditioner indoor unit, to form a first refrigerant transmission path of "air conditioner outdoor unit-air conditioner indoor unit-air conditioner outdoor unit", and then the refrigerant transmission between the air conditioner indoor unit and the air conditioner outdoor unit on the path is carried out to realize refrigeration.

[0082] At the same time, the refrigerant reversing valve is controlled to open the ports connected with the refrigerant input pipeline and the refrigerant output pipeline of the heat exchanger of the range hood, to form a second refrigerant transmission path of "air conditioner outdoor unit-range hood-air conditioner outdoor unit", and then the part of heat flowing from the air conditioner outdoor unit to the air conditioner indoor unit is diverted to the environment contacted by the range hood for evaporation and heat absorption.

[0083] According to the operating mode of the range hood, the flow rates of the first refrigerant transmission path and the second refrigerant transmission path are adjusted.

[0084] The operating mode of the range hood includes a plurality of exhaust air speed gears in sequence increasing, and the exhaust air speed gears are positively correlated with the firepower gears of the cooktop.

[0085] Specifically, during the process of controlling the air conditioner outdoor unit to provide refrigeration capacity to the air conditioner indoor unit and the range hood at the same time, the air conditioner control device sharing the outdoor unit adjusts the flow rates of the first refrigerant transmission path and the second refrigerant transmission path in combination with the operating mode of the range hood, on the premise that the sum of the flow rates of the first refrigerant transmission path and the second refrigerant transmission path is the rated flow rate value, to balance the refrigeration capacity generated by the air conditioner and the range hood in different operating modes.

[0086] The operation mode of the range hood includes multiple exhaust air speed gears in ascending order of air speed values, and in addition to manually starting a specified exhaust air speed gear, a corresponding exhaust air speed gear can also be activated according to the real-time fire condition of the cooking appliance; when the fire is determined to be the most intense according to the temperature sensed above the stove or the operating state of the cooking appliance itself, the range hood is automatically controlled to increase the exhaust air speed according to the positive correlation mapping relationship between the exhaust air speed gear and the fire gear of the cooking appliance, so as to speed up the exhaust efficiency.

[0087] In the process of determining the refrigeration of the air conditioner, when the range hood is started to work, the first refrigerant transmission path and the second refrigerant transmission path are opened, and the flow rates of the corresponding paths are adjusted to match the operation mode of the range hood. According to the fact that the air conditioner and the range hood both need to evaporate and absorb heat from the environment when releasing heat during cooking, the refrigerant transmission flow rates required when the air conditioner outdoor unit is connected to the parallel range hood and air conditioner indoor unit are adaptively adjusted. The refrigeration capacity generated by the air conditioner and the range hood during evaporation and heat absorption is dynamically adjusted according to different operation modes of the range hood, and the control performance and user experience of the air conditioner are optimized.

[0088] On the basis of any of the above embodiments, adjusting the flow rates of the first refrigerant transmission path and the second refrigerant transmission path according to the operation mode of the range hood includes: setting the second opening degree change value as k / 2n+1 and the first opening degree change value as (2n+1-k) / 2n+1 according to the sequence number k corresponding to the position of the range hood in the n ascending exhaust air speed gears.

[0089] Wherein, n is a positive integer greater than or equal to 2, and k is a positive integer less than or equal to n. The first opening degree change value is used for the refrigerant reversing valve to adjust the flow rate of the first refrigerant transmission path, and the second opening degree change value is used for the refrigerant reversing valve to adjust the flow rate of the second refrigerant transmission path.

[0090] Specifically, the air conditioner control device based on the shared outdoor unit takes the minimum rated value and the maximum rated value of the range hood exhaust air speed as the starting point and the ending point of the threshold interval, respectively, divides n-1 points within the threshold interval to obtain n ascending exhaust air speed intervals representing corresponding exhaust air speed gears, and performs flow distribution around the currently activated kth exhaust air speed gear. The distribution strategy first ensures that the refrigeration capacity of the air conditioner indoor unit accounts for at least half of the total heat exchange capacity, so the second opening degree change value can be set as k / 2n+1, and the first opening degree change value can be set as (2n+1-k) / 2n+1.

[0091] Wherein, with the increase of k value, the second opening degree change value increases, and then the heat exchanger refrigerating capacity of the range hood increases, even if the k value increases to n, the second opening degree change value of the range hood can only increase to n / 2n+1, and the first opening degree change value of the air conditioner correspondingly decreases to n+1 / 2n+1, so that the air conditioner refrigerating capacity accounts for at least half of the share.

[0092] The embodiment of the present application does not make specific limitation on the division of the exhaust air speed gear.

[0093] Alternatively, the exhaust air speed gear can be set up only two gears.

[0094] If the currently activated exhaust air speed gear of the range hood is the first exhaust air speed gear with low wind speed, the corresponding first opening degree change value is set to 4 / 5, and the second opening degree change value is set to 1 / 5, so as to reduce the flow to the range hood, and preferentially ensure the refrigeration performance of the air conditioner while executing the oil dirt cooling interception with low efficiency.

[0095] If the currently activated exhaust air speed gear of the range hood is the second exhaust air speed gear with high wind speed, the corresponding first opening degree change value is set to 3 / 5, and the second opening degree change value is set to 2 / 5, so as to reduce the flow to the range hood, slightly improve the oil dirt cooling interception efficiency while still preferentially ensuring the refrigeration performance of the air conditioner.

[0096] It can be understood that after the exhaust air speed gear is divided, a set of opening degree change values corresponding to the two refrigerant transmission paths can be preset for each exhaust air speed gear according to the above calculation method of the opening degree change value. After the sequence number k of the activated exhaust air speed gear of the range hood is determined, the second opening degree change value is k / 2n+1, and the first opening degree change value is (2n+1-k) / 2n+1 according to the pre-stored mapping relationship.

[0097] The embodiment of the present application is based on the magnitude division of the exhaust air speed gear, so that the adjustment amount of the refrigerant reversing valve with respect to the two parallel refrigerant transmission paths is determined as the corresponding opening degree change value in the magnitude, which realizes the quantitative adjustment of the opening degree of the refrigerant reversing valve with respect to different refrigerant transmission paths according to the actually activated exhaust air speed gear, dynamically maintains the performance balance of the range hood and the air conditioner, and saves energy.

[0098] On the basis of any of the above embodiments, after the heat exchange of the air conditioner indoor unit and the air conditioner outdoor unit in the refrigeration mode is controlled, the method further comprises: in the case that the air conditioner is in the refrigeration mode and the range hood is not in the running state, adjusting the running frequency of the air conditioner outdoor unit to the rated value, then opening the first refrigerant transmission path and closing the second refrigerant transmission path through the refrigerant reversing valve.

[0099] Specifically, after step 101, based on the shared outdoor unit air conditioner control device, if it is determined that the air conditioner has executed the refrigeration mode, and the range hood has not performed the exhaust, then only the port connected with the refrigerant input pipeline and the refrigerant output pipeline of the air conditioner outdoor unit and the refrigerant input pipeline and the refrigerant output pipeline of the air conditioner indoor unit of the refrigerant reversing valve is opened, and the operating frequency of the air conditioner outdoor unit is adjusted to the rated maximum value, and then the first refrigerant transmission path composed of the air conditioner outdoor unit-air conditioner indoor unit-air conditioner outdoor unit outputs the refrigerant at full capacity, and then only the refrigerant transmission between the air conditioner indoor unit and the air conditioner outdoor unit is performed on the path to realize refrigeration.

[0100] In the embodiment of the application, when it is determined that the air conditioner is operating in the refrigeration mode and the range hood is not started, it is decided to directly open the first refrigerant transmission path for the air conditioner to perform the refrigeration cycle. According to the operation condition of only the air conditioner in the refrigeration mode, only the refrigerant transmission path between the air conditioner indoor unit and the air conditioner outdoor unit is kept connected, so as to fully ensure the refrigeration capacity of the air conditioner when the range hood does not share the outdoor unit with the indoor unit, and the control performance of the air conditioner and the user experience are optimized.

[0101] On the basis of any of the above embodiments, the method further comprises: opening the second refrigerant transmission path by the refrigerant reversing valve and closing the first refrigerant transmission path when it is determined that the cooktop is turned on and that there is no human individual in the target indoor space by the radar module.

[0102] Specifically, the air conditioner control device based on the shared outdoor unit receives an activation instruction sent by the user through a transmission medium, and first makes the air conditioner indoor unit in a standby state. If it is determined that the cooktop in the target space has been turned on, but it is sensed that there is no any human individual in the target indoor space, then in the case that the use intention of the air conditioner is not clear, only the port connected with the refrigerant input pipeline and the refrigerant output pipeline of the heat exchanger of the range hood of the refrigerant reversing valve is opened to constitute the second refrigerant transmission path of the air conditioner outdoor unit-range hood-air conditioner outdoor unit, while the air conditioner continues to remain in the standby state, and then only the refrigerant transmission between the range hood and the air conditioner outdoor unit is performed on the path to evaporate and absorb heat from the environment contacted by the range hood, and further judgment is made on the heat absorption degree of the range hood.

[0103] According to the operating mode of the range hood, the operating frequency of the air conditioner outdoor unit is adjusted so as to match the flow of the second refrigerant transmission path with the operating mode of the range hood under the action of the air conditioner outdoor unit.

[0104] Specifically, in the process of only controlling the air conditioner outdoor unit to provide the refrigeration capacity to the range hood, the operating frequency of the air conditioner outdoor unit is adjusted according to the operating mode of the range hood, so as to allocate the corresponding refrigeration capacity to the range hood of different operating modes under the action of the air conditioner outdoor unit corresponding to the operating frequency.

[0105] The greater the exhaust air speed level activated by the range hood, the greater the operating frequency of the air conditioner outdoor unit needs to compress a corresponding amount of refrigerant to flow to the heat exchanger of the range hood to adapt the refrigerating capacity.

[0106] In the embodiment of the application, when the range hood is started to work in the process of determining the standby of the air conditioner, the second refrigerant transmission path is directly opened, and the operating frequency of the air conditioner outdoor unit is adjusted, so that the heat exchange amount of the range hood in the second refrigerant transmission path for refrigeration cycle is adapted to the operating mode of the range hood. The refrigerant transmission flow required when the air conditioner outdoor unit and the range hood are connected can be adaptively adjusted, the refrigerating capacity generated by the range hood during evaporation and heat absorption is dynamically adjusted according to different operating modes of the range hood, and the control performance and user experience of the range hood are optimized.

[0107] On the basis of any of the above embodiments, the operating frequency of the air conditioner outdoor unit is adjusted according to the operating mode of the range hood, including: if the exhaust air speed level of the range hood is the lowest level, the operating frequency of the air conditioner outdoor unit is adjusted to a first target value.

[0108] If the exhaust air speed level of the range hood is not the lowest level, the operating frequency of the air conditioner outdoor unit is adjusted to a second target value.

[0109] The second target value is greater than the first target value.

[0110] Specifically, the air conditioner control device based on a shared outdoor unit can execute two operating frequency adjustment strategies according to the size of the exhaust air speed level, including:

[0111] One is that if the activated exhaust air speed level is the lowest level, the operating frequency of the air conditioner outdoor unit is adjusted to a first target value with a smaller value, so that the air conditioner outdoor unit maintains a lower operating frequency for refrigerant compression in each refrigeration cycle in the second refrigerant transmission path. Two is that if the activated exhaust air speed level is not the lowest level, the operating frequency of the air conditioner outdoor unit is adjusted to a second target value with a larger value, so that the air conditioner outdoor unit maintains a higher operating frequency for refrigerant compression in each refrigeration cycle in the second refrigerant transmission path.

[0112] According to the comparison of the exhaust air speed level and the lowest level, the embodiment of the application determines that the adjustment amount of the operating frequency of the air conditioner outdoor unit is determined as the corresponding target value at this magnitude, so as to quantitatively adjust the operating frequency of the air conditioner outdoor unit according to the actually activated exhaust air speed level, match the performance balance of the range hood, and save energy.

[0113] Figure 2 is a structural schematic diagram of the air conditioner control device based on a shared outdoor unit provided by the application. On the basis of any of the above embodiments, asFigure 2 As shown, the device comprises an air conditioner starting module 210 and a first joint control module 220, wherein:

[0114] The air conditioner starting module 210 is configured to control the air conditioner indoor unit and the air conditioner outdoor unit to exchange heat in the cooling mode when it is determined that the stove is turned on and there is at least one human individual in the target indoor space determined by the radar module.

[0115] The first joint control module 220 is configured to control the air conditioner outdoor unit to exchange heat with the air conditioner indoor unit and the range hood in parallel to cool the oil fume and dirty air sucked by the range hood on the basis of continuously supplying the air conditioner indoor unit with cooling.

[0116] The target indoor space is an indoor space shared by the air conditioner indoor unit and the range hood. The range hood is provided with a heat exchanger in the exhaust duct to circulate refrigerant between the range hood and the air conditioner outdoor unit.

[0117] Specifically, the air conditioner starting module 210 and the first joint control module 220 are sequentially electrically connected.

[0118] The air conditioner starting module 210 receives an activation instruction sent by a user through a transmission medium, first makes the air conditioner indoor unit in a standby state, and then uses the radar module provided on the air conditioner indoor unit to calculate and analyze the electromagnetic waves reflected by the human body in the target indoor space. Whether there is a human individual in the space is represented by the current position of all human individuals analyzed.

[0119] If it is determined that the stove in the target space has been turned on and there is at least one human individual in the target indoor space, it means that the human individual is currently staying in the target indoor space for cooking and intends to adjust and reduce the indoor temperature by activating the cooling mode of the air conditioner. The air conditioner indoor unit and the air conditioner outdoor unit in the air conditioner are started to exchange heat in the cooling mode.

[0120] On the contrary, if it is determined that the stove in the target space has been turned on, but there is no human individual in the target indoor space, it means that the human individual may have forgotten to turn off the stove after completing cooking in the target indoor space, or the human individual may have temporarily left during a long cooking process. At this time, the intention is not clear, and the air conditioner needs to continue to remain in the standby state, and whether the air conditioner outdoor unit exchanges heat with the range hood needs to be further judged in combination with the working condition of the range hood.

[0121] If it is determined that the stove in the target space has not been turned on and there is no human individual in the target indoor space, it means that the human individual is not cooking in the target indoor space, and the activated cooling mode of the air conditioner may be a misoperation. The air conditioner needs to continue to remain in the standby state and does not provide heat exchange to any of the air conditioner indoor unit and the range hood.

[0126] The passage adjusting unit is configured to adjust the flow rates of the first refrigerant transmission passage and the second refrigerant transmission passage according to the operating mode of the range hood.

[0130] Optionally, the device further comprises a second joint control module, wherein:

[0131] The second joint control module is configured to, in a case where it is determined that the air conditioner is in a cooling mode and the range hood is not in an operating state, open the first refrigerant transmission path and close the second refrigerant transmission path by means of the refrigerant reversing valve after adjusting the operating frequency of the air conditioner outdoor unit to a rated value.

[0132] Optionally, the device further comprises a third joint control module and an outdoor unit adjustment module, wherein:

[0133] The third joint control module is configured to, in a case where it is determined that the cooking appliance is turned on and no human individual is present in the target indoor space as determined by the radar module, open the second refrigerant transmission path and close the first refrigerant transmission path by means of the refrigerant reversing valve.

[0138] The air conditioner control device based on a shared outdoor unit provided by the embodiments of the present application is used to execute the air conditioner control method based on a shared outdoor unit as described above, and the implementation manners thereof are consistent with those of the air conditioner control method based on a shared outdoor unit provided by the present application, and the same beneficial effects can be achieved, which will not be described herein again.

[0139] When the radar module provided by the indoor unit senses that a human individual is present in the target indoor space and uses the stove to cook, the embodiments of the present application decide to start the cooling mode of the air conditioner, and at the same time, open a parallel transmission branch for the heat exchanger of the range hood in the circuit flowing from the condenser of the air conditioner outdoor unit to the indoor unit of the air conditioner after heat release, so that the heat exchanger of the range hood and the indoor unit of the air conditioner are both evaporated and heat-absorbed. Based on the sensing of the distribution of human individuals in the indoor space, the refrigerant transmission mode can be cooperatively controlled in combination with the real-time working conditions of the air conditioner and the range hood, so that the heat exchange amount output by the outdoor unit when serving as a condenser is partially or entirely applied to the range hood for cooling interception, the oil smoke separation effect is improved, the pollution of oil smoke to the atmospheric environment is reduced, and the control performance and user experience of the air conditioner are optimized.

[0140] Figure 3 is one of the structural schematic diagrams of the air conditioning system provided by the present application. On the basis of any of the above embodiments, as shown in Figure 3 the air conditioning system comprises an indoor unit 310, an air conditioning outdoor unit 320, and a main system pipeline 330 for communicating the indoor unit 310 and the air conditioning outdoor unit 320.

[0141] The indoor unit 310 comprises an air conditioning indoor unit 311 and a range hood 312, and the air conditioning indoor unit 311 is provided with a radar module 311-1. The range hood 312 is provided with a heat exchanger 312-1 in the exhaust duct, so that the range hood 312 and the air conditioning outdoor unit 320 can circulate refrigerant.

[0142] The main system pipeline 330 comprises a number of refrigerant transmission channels equal to the number of parallel devices in the indoor unit 310.

[0143] The air conditioning indoor unit 311 is used to implement the air conditioning control method based on a shared outdoor unit as described in any of the above embodiments when executing a program, so as to control the air conditioning outdoor unit 320 to exchange heat with the parallel air conditioning indoor unit 311 and range hood 312 respectively when it is determined that the cooktop and the range hood 312 are both turned on, and it is determined by the radar module 311-1 that there is at least one human individual in the target indoor space, so that the air conditioning outdoor unit 320 not only continuously supplies the air conditioning indoor unit 311 with refrigeration, but also supplies the range hood 312 with cooling of the inhaled oil smoke and dirty air.

[0144] Among them, the target indoor space is an indoor space shared by the air conditioning indoor unit 311 and the range hood 312.

[0145] Specifically, in the air conditioning system, the air conditioner and the range hood 312 are connected in communication by relying on the same local area network, and for a split type air conditioner, the air conditioning indoor unit 311 included therein is arranged together with the range hood 312 in an indoor subarea (i.e. the target indoor space) for human individuals to perform cooking activities at a suitable room temperature.

[0146] The two parallel air conditioning indoor units 311 and range hoods 312 in the indoor unit 310 are connected to the air conditioning outdoor unit 320 through two refrigerant transmission channels in the main system pipeline 330, respectively. The steps of joint control are as follows:

[0147] The air conditioning indoor unit 311 receives an activation instruction sent by the user through a transmission medium, first makes the air conditioning indoor unit 311 in a standby state, and then uses the radar module 311-1 arranged on the air conditioning indoor unit 311 to calculate and analyze the electromagnetic waves reflected by the human body in the target indoor space, and determines whether there is a human individual in the space through the current position of all human individuals analyzed.

[0148] If it is determined that the stove in the target indoor space has been turned on and there is at least one human individual in the target indoor space, it means that the human individual is currently staying in the target indoor space for cooking, and intends to adjust and reduce the indoor temperature by activating the cooling mode of the air conditioner, so the air conditioner indoor unit 311 and the air conditioner outdoor unit 320 in the air conditioner are started to perform heat exchange in the cooling mode.

[0149] Further analysis is made in combination with the working condition of the air conditioner and the working condition of the range hood 312:

[0150] If it is determined that the air conditioner has performed the cooling mode and the range hood 312 is in the working state, a parallel branch is opened in the process of transferring the heat released after condensation of the air conditioner outdoor unit 320 to the air conditioner indoor unit 311, so that part of the refrigerant flowing out of the air conditioner outdoor unit 320 directly flows to the air conditioner indoor unit 311 for evaporation and heat absorption, and the other part of the refrigerant flows to the heat exchanger 312-1 in the range hood 312 for evaporation and heat absorption, so that the range hood 312 cools the oil and smoke contaminated air discharged through the exhaust duct by using the low-temperature and low-pressure liquid refrigerant carried by the heat exchanger 312-1 in the air duct while the air conditioner outdoor unit 320 supplies the air conditioner indoor unit 311 with cooling.

[0151] When the embodiment of the application senses that there is a human individual using the stove for cooking in the target indoor space through the radar module arranged in the indoor unit, the cooling mode of the air conditioner is started, and a parallel transmission branch is opened for the heat exchanger of the range hood in the circuit of the refrigerant flowing from the air conditioner outdoor unit to the air conditioner indoor unit after condensation and heat release, so that the air conditioner indoor unit and the heat exchanger of the range hood both evaporate and absorb heat. Based on the sensing of the distribution of human individuals in the indoor space, the real-time working conditions of the air conditioner and the range hood are combined to cooperatively control the refrigerant transmission mode, so that part or all of the heat exchange amount output by the outdoor unit as a condenser is applied to the range hood for cooling and interception, the oil smoke separation effect is improved, the pollution of oil smoke to the atmospheric environment is reduced, and the control performance and user experience of the air conditioner are optimized.

[0156] The refrigerant reversing valve is further provided with a fifth port and a sixth port connected with the refrigerant output pipeline and the refrigerant input pipeline of the air conditioner indoor unit 311 respectively.

[0157] When the first port, the second port, the third port and the fourth port are all opened, a first refrigerant transmission path for connecting the air conditioner outdoor unit 320 and the air conditioner indoor unit 311 to transmit refrigerant is formed.

[0158] When the first port, the second port, the fifth port and the sixth port are all opened, a second refrigerant transmission path for connecting the air conditioner outdoor unit 320 and the range hood 311 to transmit refrigerant is formed.
