Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioning equipment, and particularly relates to an air conditioner control method and device based on a shared outdoor unit and an air conditioner system. BACKGROUND

[0002] With the development of society and the continuous improvement of people's living standards, people's requirements for the quality of life are also getting higher and higher. People pay more and more attention to the comfort of the living environment, and the demand for environmental regulation equipment in daily life or work is not limited to the traditional function, but more to hope that they can adjust in various forms according to the real-time needs of users. The environmental regulation equipment can be an air conditioner and other household appliances for regulating environmental air parameters.

[0003] However, most of the current environmental regulation equipment cannot well interpret the concept of interconnection with other devices due to the limitations of their own functions and structures. For example, the current air conditioner and washing machine cannot be effectively interconnected, and cannot be intelligently adjusted according to the actual state of each other. Especially when the air conditioner and the washing machine work at the same time, the heat emitted by the condenser of the outdoor unit in the cooling mode is discharged to the atmosphere in the form of hot air, causing a great waste of heat. And the washing machine will heat the washing water to the rated temperature during the execution of the washing operation, which will inevitably cause the waste of electric energy. Therefore, how to use the waste heat energy generated by the outdoor unit in the washing mode of the washing machine while ensuring the normal operation of the air conditioner is an important issue to be solved in the industry at present.

[0048] 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.

[0049] Figure 1 is one of the flow diagrams 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: step 101, determining that at least one human individual exists in a first indoor partition through a radar module, and controlling the air conditioner indoor unit and the air conditioner outdoor unit to perform heat exchange in a corresponding working mode.

[0050] The air conditioner comprises an air conditioner indoor unit in the first indoor partition, and an air conditioner outdoor unit in a second indoor partition together with the washing machine. The radar module is arranged in the air conditioner indoor unit. The second indoor partition is any indoor partition independent of the first indoor partition.

[0051] It should be noted that the execution subject of the air conditioner control method based on the shared outdoor unit provided by the embodiment of the present application is an air conditioner control device based on the shared outdoor unit, which can be arranged in the air conditioner.

[0052] The application scenario of the air conditioner control method based on the shared outdoor unit is that the outdoor unit of the air conditioner and the washing machine are in the same indoor environment and are communicatively connected by the same local area network. When the user activates the air conditioner, the radar module on the indoor unit performs human body sensing on the space where the user is located, and adjusts the working states of the air conditioner and the washing machine accordingly.

[0053] The air conditioner and the washing machine are communicatively connected by the same local area network. For a split-type air conditioner, the air conditioner indoor unit included in the air conditioner is arranged in a first indoor subzone for human individuals to perform daily activities at a suitable room temperature, and the air conditioner outdoor unit is in a second indoor subzone that is different from the first indoor subzone and exists independently.

[0054] The distribution and effect of the first indoor subzone and the second indoor subzone in the indoor space are not specifically limited.

[0055] For example, the first indoor subzone and the second indoor subzone are in an abutting relationship in front and back, so that the human individual can come to the second indoor subzone to wash clothes by the washing machine after leaving the first indoor subzone. For example, the first indoor subzone can be a living room, and the second indoor subzone can be a balcony that is in communication with the living room.

[0056] For example, the first indoor subzone and the second indoor subzone can also not necessarily have an abutting relationship, so that the human individual can come to the second indoor subzone to wash clothes by the washing machine after leaving the first indoor subzone via other indoor subzones. For example, the first indoor subzone can be a bedroom, and the second indoor subzone can be a balcony that is in communication with the living room.

[0057] It should be noted that before step 101, the user needs to send corresponding activation instructions to the air conditioner and the washing machine through a transmission medium to activate the desired working mode of the air conditioner in the indoor space where the user is currently located, and to activate the washing machine to execute the desired washing program of the user.

[0058] Optionally, the user can transmit the activation instructions by a control device in a wireless communication manner between the control device and the air conditioning system, initialize the entire air conditioning system, and start the radar module arranged on the air conditioner indoor unit.

[0059] Optionally, the user can issue the activation instructions in a voice interaction manner, the air conditioning system receives the activation instructions, performs voice recognition, initializes, and then starts the radar module arranged on the air conditioner indoor unit.

[0060] Specifically, in step 101, the air conditioner control device based on the shared outdoor unit receives an activation instruction sent by the user through a transmission medium, first makes the air conditioner indoor unit in a standby state, and then uses the radar module to calculate and analyze the electromagnetic waves reflected by the human body in the first indoor partition, and determines whether there is a human body in the space through the current position of all human individuals analyzed:

[0061] If it is determined that there is at least one human individual in the first indoor partition, it means that the human individual is currently staying in the first indoor partition and has the intention to adjust the indoor temperature by activating the working mode of the air conditioner, and the air conditioner is controlled to switch from the standby state to the working mode of the air conditioner indicated by the activation instruction, so that the air conditioner indoor unit and the air conditioner outdoor unit perform heat exchange in the corresponding working mode.

[0062] If it is determined that there is no human individual in the first indoor partition, it means that the human individual is currently not in the first indoor partition, and the working mode of the air conditioner started may be a misoperation or a pre-operation by the user before entering the first indoor partition. The air conditioner is controlled to continue to remain in the standby state until the user enters the first indoor space and starts the air conditioner indoor unit and the air conditioner outdoor unit to perform heat exchange in the corresponding working mode.

[0063] Among them, the type and number of radar sensing devices in the radar module are not specifically limited.

[0064] For example, the radar module can include a laser radar, an infrared sensor, etc.

[0065] Optionally, the horizontal detection range of the millimeter wave radar can reach ±75°, the vertical detection range can reach ±40°, the detection distance can reach 8 meters, the distance output accuracy can reach 0.1 meters, the angle output accuracy can reach 1°, and there is no privacy problem and no light influence. Its response speed is also faster.

[0066] 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 there is a human individual in the indoor space.

[0067] For example, the radar module can include multiple types of sensing elements such as millimeter wave radar, laser radar, infrared sensor, etc., and 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 each sensing element to comprehensively sense whether there is a human individual in the indoor space where the air conditioner is located.

[0068] Step 102, in the case that the working mode is determined to be the refrigeration mode and the washing machine starts the washing program, the indoor unit of the air conditioner and the outdoor unit of the air conditioner in parallel are controlled to exchange heat, so that the washing machine uses the heat exchange amount generated by the refrigeration of the air conditioner to heat the washing water.

[0069] It should be noted that before step 102, the washing machine receives the activation instruction sent by the user through the transmission medium, starts the corresponding washing program according to the instruction content in real time or at a fixed time, and feeds back a notification message to the air conditioner control device based on the shared outdoor unit to indicate that the washing machine has started the washing program, so that the working condition of the washing machine is known.

[0070] Specifically, in step 102, the air conditioner control device based on the shared outdoor unit analyzes the working condition of the air conditioner and the working condition of the washing machine:

[0071] If it is determined that the air conditioner has executed the refrigeration mode and the washing machine has started the washing program, a parallel branch is opened for the process of returning to the air conditioner outdoor unit from the air conditioner indoor unit after evaporative heat absorption, so that the refrigerant flows out of the air conditioner indoor unit, part of which directly flows to the air conditioner outdoor unit for the next refrigeration cycle, and the other part of the refrigerant first flows to the washing machine for washing water heating, and then flows to the air conditioner outdoor unit for the next refrigeration cycle.

[0072] Among them, the process of refrigeration cycle is that the refrigerant first becomes high-pressure gas through the compressor in the air conditioner outdoor unit, then condenses and releases heat to become high-pressure liquid through the heat exchanger of the air conditioner outdoor unit (which plays the role of condenser at this time), then the high-pressure liquid passes through the refrigerant transmission channel to become low-temperature and low-pressure liquid, and then passes through the heat exchanger of the air conditioner indoor unit (which plays the role of evaporator at this time) to evaporate and absorb heat, while reducing the temperature of indoor air, so as to achieve the purpose of reducing the indoor temperature, and become low-temperature and low-pressure gas into the compressor for the next refrigeration cycle.

[0073] On the contrary, if any of the working conditions of the air conditioner and the working condition of the washing machine does not meet the above requirements, the heat exchange amount generated by the refrigeration of the air conditioner is not used to heat the washing water.

[0074] The embodiment of the present application starts the corresponding working mode of the air conditioner when the radar module arranged in the indoor unit senses the presence of a human individual in the first indoor partition. If the air conditioner is operating in the cooling mode and the washing machine has started the washing program, a parallel return branch is opened for the washing machine in the process of return flow to the outdoor unit of the air conditioner after the evaporative heat absorption of the indoor unit of the air conditioner, so that the washing machine uses the heat exchange amount generated by the air conditioner in the cooling mode to heat the washing water. Based on the sensing of the distribution of human individuals in the room, the real-time working conditions of the air conditioner and the washing machine are combined for collaborative control, and all or part of the refrigerant returned to the outdoor unit of the air conditioner in the cooling mode is selectively used to improve the washing water temperature of the washing machine. The heat released by the outdoor unit when used as a condenser can be applied to the washing machine, which not only avoids the consumption of additional electric energy by the washing machine itself to perform the washing task, but also reduces the waste of heat energy of the air conditioner, optimizes the control performance of the air conditioner and the user experience.

[0075] On the basis of any of the above embodiments, in the case that the working mode is determined to be the cooling mode and the washing machine is determined to have started the washing program, the indoor unit of the air conditioner is controlled to exchange heat with the parallel outdoor unit of the air conditioner and the washing machine, respectively, so that the washing machine uses the heat exchange amount generated by the air conditioner in the cooling mode to heat the washing water, including: in the case that the working mode is determined to be the cooling mode and the washing machine is determined to have started the washing program, opening the first refrigerant transmission path and the second refrigerant transmission path through the refrigerant reversing valve.

[0076] The indoor unit of the air conditioner is connected to the washing machine and / or the outdoor unit of the air conditioner through a refrigerant reversing valve. The first refrigerant transmission path is used to connect the refrigerant transmission between the indoor unit of the air conditioner and the outdoor unit of the air conditioner. The second refrigerant transmission path is used to connect the refrigerant transmission between the indoor unit of the air conditioner and the washing machine.

[0077] It should be noted that the air conditioner and the washing machine are connected through a refrigerant reversing valve. In addition to the ports connected to the refrigerant input pipeline and the refrigerant output pipeline of the outdoor unit of the air conditioner and the refrigerant input pipeline and the refrigerant output pipeline of the indoor unit of the air conditioner, the refrigerant reversing valve also has a port connected to the refrigerant input pipeline of the washing machine, and the refrigerant output pipeline of the washing machine is connected to the refrigerant input pipeline of the outdoor unit of the air conditioner, so as to form two closed paths about the parallel arrangement of the washing machine and the outdoor unit of the air conditioner.

[0078] Specifically, in step 102, based on the shared outdoor unit air conditioner control device if it is determined that the air conditioner has performed the refrigeration mode, and the washing machine has started the washing program, then control the refrigerant reversing valve to open 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 to form a first refrigerant transmission path of "air conditioner outdoor unit-air conditioner indoor unit-air conditioner outdoor unit", and then perform refrigerant transmission between the air conditioner indoor unit and the air conditioner outdoor unit on the path to realize refrigeration.

[0079] At the same time, control the refrigerant reversing valve to open the port connected with the refrigerant input pipeline of the washing machine to form a second refrigerant transmission path of "air conditioner outdoor unit-air conditioner indoor unit-washing machine-air conditioner outdoor unit", and then divert part of the heat of the air conditioner indoor unit backflow to the air conditioner outdoor unit to the washing machine interior for washing water heating.

[0080] Based on the indoor set temperature and the outdoor unit coil temperature collected by the sensing module on the air conditioner outdoor unit, the flow rates of the first refrigerant transmission path and the second refrigerant transmission path are adjusted.

[0081] The indoor set temperature is the temperature set when the working mode is activated

[0082] It should be noted that the indoor set temperature refers to the temperature value set by a human individual when the first indoor partition sends an activation instruction to the air conditioner, and the temperature value is the indoor temperature value expected to be achieved by the human individual in the first indoor partition.

[0083] The embodiment of the application does not make specific limitations on the value thereof. Generally, the indoor set temperature in the refrigeration mode is generally less than or equal to 26 degrees Celsius.

[0084] It should be noted that a sensing module for sensing temperature is also provided on the coil of the heat exchanger in the air conditioner outdoor unit to output the temperature value collected by the air conditioner outdoor unit when the air conditioner outdoor unit performs the refrigeration mode as the outdoor unit coil temperature.

[0085] Specifically, the shared outdoor unit air conditioner control device monitors the working capacity of the air conditioner outdoor unit in real time through the sensing module provided on the air conditioner outdoor unit during the air conditioner refrigeration process, calculates the compression ratio using the indoor set temperature pre-set for the air conditioner indoor unit and the current outdoor unit coil temperature on the air conditioner outdoor unit, and maintains the compression ratio of the air conditioner within an optimal range by adjusting the flow rates of the first refrigerant transmission path and the second refrigerant transmission path.

[0086] The greater the compression ratio of the air conditioner, the greater the inability of the compressor to suck in the refrigerant vapor, thereby losing refrigeration capacity, and thus the flow of the second refrigerant transmission path needs to be greater than that of the first refrigerant transmission path to reduce the compression ratio to a suitable threshold range to achieve the best refrigeration effect.

[0087] When it is determined that the air conditioner is operating in the refrigeration mode and the washing machine has started the washing program, the indoor set temperature set at the air conditioner indoor unit and the outdoor coil temperature fed back by the air conditioner outdoor unit are used to adjust the flow of the corresponding path after the first refrigerant transmission path and the second refrigerant transmission path are opened. In the case that the washing machine is also in operation when the air conditioner is in refrigeration, the refrigerant transmission flow when the air conditioner indoor unit is connected to the parallel washing machine and air conditioner outdoor unit is adaptively adjusted to maximize the use of excess heat to the washing machine for washing water heating while ensuring the refrigeration capacity of the air conditioner, avoiding over-compression or under-compression of the air conditioner outdoor unit during sharing, and optimizing the control performance and user experience of the air conditioner.

[0088] On the basis of any of the above embodiments, the flow of the first refrigerant transmission path and the second refrigerant transmission path is adjusted based on the indoor set temperature and the outdoor coil temperature collected by the sensor module on the air conditioner outdoor unit, including: based on the indoor set temperature and the outdoor coil temperature, obtaining a target temperature difference.

[0089] Specifically, the air conditioner control device based on the shared outdoor unit calculates the difference between the outdoor coil temperature and the indoor set temperature, and the target temperature difference ΔT obtained by it approximately represents the operating capacity of the air conditioner outdoor unit in the refrigeration mode.

[0090] According to the target temperature difference corresponding to the target temperature difference sub-interval, the first opening degree change value and the second opening degree change value of the refrigerant reversing valve are determined, so that the refrigerant reversing valve adjusts the opening degree of the first refrigerant transmission path according to the first opening degree change value, and adjusts the opening degree of the second refrigerant transmission path according to the second opening degree change value.

[0091] The target temperature difference sub-interval is one of all temperature difference sub-intervals. Any of the temperature difference sub-intervals is respectively provided with a group of opening degree change values of the first refrigerant transmission path and the second refrigerant transmission path.

[0092] It should be noted that before this step, at least two consecutive temperature difference sub-intervals need to be divided between the upper limit and the lower limit of the target temperature difference to quantify different temperature difference levels.

[0093] Correspondingly, a plurality of temperature difference levels set according to the number of temperature difference sub-intervals are also needed, which divide the opening degree change value of the refrigerant reversing valve in the first refrigerant transmission path and the opening degree change value of the refrigerant reversing valve in the second refrigerant transmission path one by one.

[0094] The target temperature difference is obtained based on the outdoor unit shared by the air conditioner control device, and the target temperature difference sub-interval corresponding to the target temperature difference is determined.

[0095] Specifically, in step 102, the air conditioner control device based on the shared outdoor unit takes the temperature difference sub-interval where the current target temperature difference as the target temperature difference sub-interval, and takes the opening degree change value of the two refrigerant transmission paths corresponding to the temperature difference sub-interval as the first opening degree change value and the second opening degree change value respectively, then encapsulates the first opening degree change value and the second opening degree change value into a control instruction, and sends it to the refrigerant reversing valve.

[0096] The refrigerant reversing valve receives and responds to the control instruction, and can execute the first opening degree change value indicated in the instruction based on the current opening degree of the first refrigerant transmission path, to adjust the refrigerant flow from the air conditioner indoor unit back to the air conditioner outdoor unit according to the opening adjustment strategy.

[0097] At the same time, the second opening degree change value indicated in the instruction can also be executed based on the current opening degree of the second refrigerant transmission path, to adjust the refrigerant flow from the air conditioner indoor unit back to the air conditioner outdoor unit via the washing machine according to the opening adjustment strategy.

[0098] The target temperature difference is obtained based on the outdoor unit shared by the air conditioner control device, and the target temperature difference sub-interval corresponding to the target temperature difference is determined.

[0099] On the basis of any of the above embodiments, according to the target temperature difference corresponding to the target temperature difference sub-interval, the first opening degree change value and the second opening degree change value of the refrigerant reversing valve are determined, including: using the serial number k corresponding to the position of the target temperature difference sub-interval in the n ascendingly arranged temperature difference sub-intervals, setting the second opening degree change value as k / n, and setting the first opening degree change value as (n-k) / n.

[0100] Wherein, n is a positive integer greater than or equal to 2, and k is a natural number less than or equal to n.

[0101] Specifically, based on the air conditioner control device sharing the outdoor unit, the minimum value and the maximum value of the target temperature difference are respectively taken as the starting point and the ending point of the threshold interval, n-1 points are set in the threshold interval for division, n ascendingly arranged temperature difference sub-intervals are obtained, and after the kth temperature difference sub-interval where the current target temperature difference is located is taken as the target temperature difference sub-interval, the second opening degree change value is set as k / n, and the first opening degree change value is also set as (n-k) / n.

[0102] Wherein, with the increase of k value, the second opening degree change value increases, and then the temperature of the heated washing water is higher.

[0103] The division of the temperature difference sub-interval is not specifically limited in the embodiment of the application.

[0104] Optionally, the first temperature difference sub-interval, the second temperature difference sub-interval, the third temperature difference sub-interval and the fourth temperature difference sub-interval in which the temperature difference increases are [0, 6], (6, 12], (12, 18] and (18, +∞) in sequence.

[0105] If the target temperature difference is in the first temperature difference sub-interval, the corresponding first opening degree change value is set as 3 / 4, and the second opening degree change value is set as 1 / 4, so as to reduce the loop flow to the washing machine and preferentially guarantee the refrigeration performance of the air conditioner.

[0106] If the target temperature difference is in the second temperature difference sub-interval, the corresponding first opening degree change value is set as 2 / 4, and the second opening degree change value is set as 2 / 4, so as to balance the loop flow to the washing machine and the loop flow directly to the outdoor unit of the air conditioner.

[0107] If the target temperature difference is in the third temperature difference sub-interval, the corresponding first opening degree change value is set as 1 / 4, and the second opening degree change value is set as 3 / 4, so as to avoid overheating of the evaporator of the outdoor unit, and by means of making most of the refrigerant return to preferentially supply the washing machine to heat the washing water, the refrigeration capacity is appropriately reduced under the premise of not wasting heat energy.

[0108] If the target temperature difference is in the third temperature difference sub-interval, the corresponding first opening degree change value is set to 0, and the second opening degree change value is set to 1, at this time, the evaporator of the outdoor unit has overheating, and the generation of the refrigeration capacity is suspended, so that the refrigerant backflow is entirely inclined to supply the washing machine to heat the washing water refrigeration capacity.

[0109] It can be understood that after the temperature difference sub-intervals are divided, a set of opening degree change values corresponding to the two refrigerant transmission paths can be preset for each temperature difference sub-interval according to the above calculation method of the opening degree change value. After the serial number k of the target temperature difference sub-interval is determined, the second opening degree change value is k / n and the first opening degree change value is (n-k) / n according to the pre-stored mapping relationship.

[0110] The embodiment of the present application divides the temperature difference sub-interval by magnitude, 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 at this magnitude, which realizes quantitative adjustment of the opening degree of the refrigerant reversing valve with respect to different refrigerant transmission paths according to the actual target temperature difference, dynamically maintains the performance balance of the washing machine and the air conditioner, and saves energy.

[0111] On the basis of any of the above embodiments, after the radar module determines that at least one human individual exists in the first indoor partition, and the air conditioner indoor unit and the air conditioner outdoor unit are controlled to perform heat exchange in the corresponding working mode, it further comprises: in the case that the working mode is determined to be a refrigeration mode and the washing machine is determined not to start a washing program, the first refrigerant transmission path is opened by the refrigerant reversing valve, so that the air conditioner indoor unit and the air conditioner outdoor unit perform refrigeration cycle.

[0112] Specifically, after step 101, based on the air conditioner control device of the shared outdoor unit, if it is determined that the air conditioner has performed a refrigeration mode and the washing machine has not started a washing program, only 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 of the refrigerant reversing valve are controlled to be opened, to form a first refrigerant transmission path of "air conditioner outdoor unit-air conditioner indoor unit-air conditioner outdoor unit", and then refrigerant transmission between the air conditioner indoor unit and the air conditioner outdoor unit is performed on the path to realize refrigeration.

[0113] When it is determined that the air conditioner is working in a refrigeration mode and the washing machine has not started a washing program, the embodiment of the present application decides to directly open the first refrigerant transmission path only for the air conditioner to perform refrigeration cycle. According to the working condition of only the air conditioner in refrigeration, only the refrigerant transmission path between the air conditioner indoor unit and the air conditioner outdoor unit is kept connected, so as to fully guarantee the refrigeration capacity of the air conditioner when the washing machine does not share the outdoor unit with the indoor unit, and optimize the control performance and user experience of the air conditioner.

[0114] On the basis of any of the above embodiments, after the first indoor partition is determined to have at least one human individual by the radar module, the air conditioner indoor unit and the air conditioner outdoor unit are controlled to perform heat exchange in the corresponding working mode, and further comprising: in the case of determining that the working mode is a heating mode, opening the first refrigerant transmission path and adjusting the flow direction through the refrigerant reversing valve, so that the air conditioner indoor unit and the air conditioner outdoor unit perform a heating cycle.

[0115] Specifically, after step 101, if the air conditioner control device based on the shared outdoor unit determines that the air conditioner has performed a heating mode, only control the refrigerant reversing valve to open the ports connected to 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 refrigerant transmission path opposite to the flow direction of the first refrigerant transmission path, that is, "air conditioner indoor unit-air conditioner outdoor unit-air conditioner indoor unit", and then perform refrigerant transmission between the air conditioner indoor unit and the air conditioner outdoor unit on the path to realize heating. Then, when the washing machine starts, the washing water is heated by the heating module itself.

[0116] Wherein, the process of the heating cycle is that the refrigerant first becomes a high-pressure gas through the compressor in the air conditioner indoor unit, then passes through the heat exchanger (which functions as a condenser at this time) in the indoor unit to condense and liquefy and release heat, becoming a liquid, and at the same time heating the indoor air to achieve the purpose of increasing the indoor temperature. The liquid refrigerant is throttled and decompressed through the refrigerant transmission path, enters the heat exchanger (which functions as an evaporator at this time) of the air conditioner outdoor unit, evaporates and absorbs heat to become a gas, and at the same time absorbs the heat of outdoor air, becoming a gas. The gaseous refrigerant enters the compressor again to start the next heating cycle.

[0117] Figure 2 is a distribution diagram of the air conditioner and the washing machine based on the shared outdoor unit provided by the present application. Figure 3 is a flowchart of the air conditioner control method based on the shared outdoor unit provided by the present application. Figure 2 and Figure 3 As shown in the figures, taking the case where the air conditioner indoor unit is arranged in the living room and the air conditioner outdoor unit and the washing machine are arranged together on the balcony as an example, the corresponding implementation of the air conditioner control method based on the shared outdoor unit is given:

[0118] (1) When the air conditioner is initialized, the air conditioner indoor unit is in standby mode, and the radar arranged on the air conditioner indoor unit is driven to capture human targets in the living room (i.e. the first indoor partition) where it is located. If there is a person in the living room, step (2) is performed, otherwise the air conditioner indoor unit continues to be in standby mode.

[0119] (2) Analyze the working conditions of the air conditioner and the working conditions of the washing machine. If the air conditioner is currently in cooling mode and the washing machine has been running, steps (3)-(4) are performed. If the air conditioner is currently in heating mode, step (5) is performed.

[0120] (3) If the air conditioner is currently in cooling mode and the washing machine has been running, open the first refrigerant transmission path and the second refrigerant transmission path through the refrigerant reversing valve.

[0121] (4) Calculate the difference between the indoor set temperature and the outdoor coil temperature, and analyze and compare the obtained target temperature difference AT with the preset temperature difference sub-interval:

[0122] If AT ∈ [0, 6], set the valve opening degree of the second refrigerant transmission path to 1 / 4 and the valve opening degree of the first refrigerant transmission path to 3 / 4 through the refrigerant reversing valve, to adjust the washing machine's cold water washing to warm water washing corresponding to the temperature, and set the valve opening degree of the second refrigerant transmission path to 0 until the washing is completed.

[0123] If AT ∈ (6, 12], set the valve opening degree of the second refrigerant transmission path to 2 / 4 and the valve opening degree of the first refrigerant transmission path to 2 / 4 through the refrigerant reversing valve, to adjust the washing machine's cold water washing to warm water washing corresponding to the temperature, and set the valve opening degree of the second refrigerant transmission path to 0 until the washing is completed.

[0124] If AT ∈ (12, 18], set the valve opening degree of the second refrigerant transmission path to 3 / 4 and the valve opening degree of the first refrigerant transmission path to 1 / 4 through the refrigerant reversing valve, to adjust the washing machine's cold water washing to warm water washing corresponding to the temperature, and set the valve opening degree of the second refrigerant transmission path to 0 until the washing is completed.

[0125] If AT ∈ (18, +∞), set the valve opening degree of the second refrigerant transmission path to 1 and the valve opening degree of the first refrigerant transmission path to 0 through the refrigerant reversing valve, to adjust the washing machine's cold water washing to warm water washing corresponding to the temperature, and set the valve opening degree of the second refrigerant transmission path to 0 until the washing is completed.

[0126] (5) If the air conditioner is currently in heating mode, whether the washing machine is running or not, open the first refrigerant transmission path and reverse the flow direction through the refrigerant reversing valve, and also set the valve opening degree of the second refrigerant transmission path to 0, i.e. the refrigerant flow to the washing machine is zero.

[0127] When the air conditioner is determined to be in heating mode, the embodiment of the present application decides to open and reverse the flow direction of the first refrigerant transmission path, which is only for the air conditioner to perform heating cycle. Regardless of the operation of the washing machine when the air conditioner is in heating mode, the refrigerant transmission path between the indoor unit of the air conditioner and the outdoor unit of the air conditioner is kept connected, which realizes that no heat exchange amount is shared with the washing machine, only the heating work of the air conditioner is performed, and the control performance and user experience of the air conditioner are optimized.

[0128] Figure 4is a structural schematic diagram of an air conditioner control device based on a shared outdoor unit provided by the present application. On the basis of any of the above embodiments, as shown in Figure 4 The device includes an air conditioner activation module 410 and a first joint control module 420, wherein:

[0129] The air conditioner activation module 410 is configured to determine that there is at least one human individual in the first indoor partition through the radar module, and control the air conditioner indoor unit and the air conditioner outdoor unit to perform heat exchange in the corresponding working mode.

[0130] The first joint control module 420 is configured to, in a case where it is determined that the working mode is a cooling mode and it is determined that the washing machine starts a washing program, control the air conditioner indoor unit to perform heat exchange with the air conditioner outdoor unit and the washing machine in parallel, so that the washing machine uses the heat exchange amount generated by the air conditioner in the cooling mode to heat the washing water.

[0131] The air conditioner includes an air conditioner indoor unit in the first indoor partition, and an air conditioner outdoor unit in the second indoor partition together with the washing machine. The radar module is arranged in the air conditioner indoor unit. The second indoor partition is any indoor partition independent of the first indoor partition.

[0132] Specifically, the air conditioner activation module 410 and the first joint control module 420 are sequentially electrically connected.

[0133] The air conditioner activation module 410 receives an activation instruction sent by a user through a transmission medium, first causes the air conditioner indoor unit to be in a standby state, and then uses the radar module to calculate and analyze the electromagnetic waves reflected by the human body in the first indoor partition. Whether there is a human individual in the space is represented by the current position of all human individuals analyzed:

[0134] If it is determined that there is at least one human individual in the first indoor partition, it means that the human individual is currently staying in the first indoor partition and has the intention to adjust the indoor temperature by activating the working mode of the air conditioner. Therefore, the air conditioner is controlled to switch from the standby state to the working mode indicated by the activation instruction, so that the air conditioner indoor unit and the air conditioner outdoor unit perform heat exchange in the corresponding working mode.

[0135] If it is determined that there is no human individual in the first indoor partition, it means that the human individual is not currently in the first indoor partition. The working mode activated by the air conditioner may be a misoperation, or the user may have performed a pre-operation before entering the first indoor partition. Therefore, the air conditioner is controlled to continue to remain in the standby state until the air conditioner indoor unit and the air conditioner outdoor unit are started to perform heat exchange in the corresponding working mode when it is sensed that the user enters the first indoor space.

[0136] The first joint control module 420 analyzes the working condition of the air conditioner and the working condition of the washing machine:

[0137] If it is determined that the air conditioner has executed the refrigeration mode and the washing machine has started the washing program, a parallel branch is opened in the refrigeration cycle of the air conditioner indoor unit and the air conditioner outdoor unit to make the refrigerant flow out of the air conditioner indoor unit, a part of which directly flows to the air conditioner outdoor unit for the next refrigeration cycle, and the other part of the refrigerant flows to the washing machine for heating the washing water and then flows to the air conditioner outdoor unit for the next refrigeration cycle.

[0138] Optionally, the first joint control module 420 comprises a passage opening unit and a passage adjusting unit, wherein:

[0139] The passage opening unit is configured to open the first refrigerant transmission passage and the second refrigerant transmission passage through the refrigerant reversing valve when it is determined that the working mode is the refrigeration mode and it is determined that the washing machine starts the washing program.

[0140] The passage adjusting unit is configured to adjust the flow of the first refrigerant transmission passage and the second refrigerant transmission passage based on the indoor set temperature and the outdoor coil temperature collected by the sensing module on the air conditioner outdoor unit.

[0141] The air conditioner indoor unit is in communication with the washing machine and / or the air conditioner outdoor unit through the refrigerant reversing valve. The indoor set temperature is the temperature set when the working mode is activated. The first refrigerant transmission passage is used to connect the refrigerant transmission between the air conditioner indoor unit and the air conditioner outdoor unit. The second refrigerant transmission passage is used to connect the refrigerant transmission between the air conditioner indoor unit and the washing machine.

[0142] Optionally, the passage adjusting unit comprises a temperature difference calculation subunit and a passage adjusting subunit, wherein:

[0143] The temperature difference calculation subunit is configured to obtain a target temperature difference based on the indoor set temperature and the outdoor coil temperature.

[0144] The passage adjusting subunit is configured to determine a first opening degree change value and a second opening degree change value of the refrigerant reversing valve according to a target temperature difference subinterval corresponding to the target temperature difference, so that the refrigerant reversing valve adjusts the opening degree of the first refrigerant transmission passage according to the first opening degree change value and adjusts the opening degree of the second refrigerant transmission passage according to the second opening degree change value.

[0145] The target temperature difference subinterval is one of all temperature difference subintervals. Any of the temperature difference subintervals is respectively provided with a set of opening degree change values of the first refrigerant transmission passage and the second refrigerant transmission passage.

[0146] Optionally, the path adjustment subunit is specifically configured to set the second opening degree change value as k / n and the first opening degree change value as (n-k) / n, where k is a serial number corresponding to a position of the target temperature difference subinterval in the n ascending temperature difference subintervals.

[0147] wherein n is a positive integer greater than or equal to 2, and k is a natural number less than or equal to n.

[0148] Optionally, the device further comprises a second joint control module, wherein:

[0149] The second joint control module is configured to, in a case where it is determined that the working mode is the refrigeration mode and it is determined that the washing machine has not started a washing program, open the first refrigerant transmission path by the refrigerant reversing valve to enable the air conditioner indoor unit and the air conditioner outdoor unit to perform a refrigeration cycle.

[0150] Optionally, the device further comprises a third joint control module, wherein:

[0151] The third joint control module is configured to, in a case where it is determined that the working mode is the heating mode, open the first refrigerant transmission path and adjust the flow direction by the refrigerant reversing valve to enable the air conditioner indoor unit and the air conditioner outdoor unit to perform a heating cycle.

[0152] 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 manner is consistent with that 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 here.

[0153] When the radar module arranged in the indoor unit senses the presence of a human individual in the first indoor subzone, the working mode of the air conditioner is started, and if the air conditioner is operating in the refrigeration mode and the washing machine has started a washing program, a parallel return flow branch is opened for the washing machine in the process of return flow to the air conditioner outdoor unit after evaporation heat absorption of the air conditioner indoor unit, so that the washing machine uses the heat exchange amount generated by the air conditioner in refrigeration to heat the washing water. Based on the sensing of the distribution of human individuals in the room, the real-time working conditions of the air conditioner and the washing machine are combined for collaborative control, and all or part of the refrigerant returned to the outdoor unit of the air conditioner in refrigeration is selectively used to improve the washing water temperature of the washing machine, and the heat released by the outdoor unit as a condenser can be applied to the washing machine, which not only avoids the consumption of additional electric energy by the washing machine itself for performing a washing task, but also reduces the waste of heat energy of the air conditioner, optimizes the control performance of the air conditioner and the user experience.

[0154] Figure 5 is a structural schematic diagram of the air conditioner system provided by the present application. Based on any of the above embodiments, as Figure 5As shown, the air conditioning system comprises an air conditioner indoor unit 510, an outdoor unit 520, and a main system pipeline 530 connecting the air conditioner indoor unit 510 and the outdoor unit 520.

[0155] The outdoor unit 520 comprises a washing machine 521 and an air conditioner outdoor unit 522 connected in parallel in a second indoor partition.

[0156] The main system pipeline 530 comprises a number of refrigerant transmission channels equal to the number of parallel devices in the outdoor unit 520.

[0157] The air conditioner indoor unit 510 is provided with a radar module 511, and the air conditioner indoor unit 510 is used to execute the program to achieve the air conditioner control method based on sharing outdoor units as described in any one of the above, to control the main system pipeline 530 to connect all refrigerant transmission channels, so that the air conditioner indoor unit 510 exchanges heat with the parallel air conditioner outdoor unit 522 and washing machine 521.

[0158] Specifically, in the air conditioning system, the air conditioner and the washing machine 521 are connected by the same local area network, and for split-type air conditioners, the air conditioner indoor unit 510 included therein is arranged in a first indoor partition for human individuals to perform daily activities at a suitable room temperature, while the air conditioner outdoor unit 522 is in a second indoor partition with the washing machine 521,

[0159] The two parallel air conditioner outdoor units 522 and washing machines 521 in the outdoor unit 120 are connected to the air conditioner indoor unit 510 through two refrigerant transmission channels in the main system pipeline 530, respectively. The steps of joint control are as follows:

[0160] The air conditioner indoor unit 510 receives an activation instruction sent by the user through a transmission medium, first makes the air conditioner indoor unit 510 in a standby state, and then uses the radar module 511 to calculate and analyze the electromagnetic waves reflected by the human body in the first indoor partition. The current position of all human individuals analyzed by the space indicates whether there are human individuals in the space:

[0161] If it is determined that there is at least one human individual in the first indoor partition, it means that the human individual is currently staying in the first indoor partition and has the intention to adjust the indoor temperature by activating the working mode of the air conditioner. Then control the air conditioner to change from standby state to the air conditioning working mode indicated by the activation instruction, so that the air conditioner indoor unit 510 and the air conditioner outdoor unit 522 exchange heat in the corresponding working mode.

[0162] If it is determined that there is no human individual in the first indoor partition, it means that the human individual is not currently in the first indoor partition, and the working mode of the air conditioner started by the air conditioner may be a misoperation or a pre-operation by the user before entering the first indoor partition. The air conditioner is controlled to continue to remain in the standby state until the user enters the first indoor space to start the air conditioner indoor unit 510 and the air conditioner outdoor unit 522 to perform heat exchange in the corresponding working mode.

[0163] Further analysis is made in combination with the working condition of the air conditioner and the working condition of the washing machine 521.

[0164] If it is determined that the air conditioner has performed the refrigeration mode and the washing machine 521 has started the washing program, a parallel branch is opened in the process of returning to the air conditioner outdoor unit 522 after evaporative heat absorption of the air conditioner indoor unit 510, so that the refrigerant flows out of the air conditioner indoor unit 510, part of which directly flows to the air conditioner outdoor unit 522 for the next refrigeration cycle, and the other part of the refrigerant first flows to the washing machine 521 for heating the washing water, and then flows to the air conditioner outdoor unit 522 for the next refrigeration cycle.

[0165] On the contrary, if any of the working conditions of the air conditioner and the washing machine does not meet the above requirements, the heat exchange amount generated by the refrigeration of the air conditioner is not used to heat the washing water.

[0166] The embodiment of the present application starts the corresponding working mode of the air conditioner when the radar module arranged in the indoor unit senses that there is a human individual in the first indoor partition. If the air conditioner operates in the refrigeration mode and the washing machine has started the washing program, a parallel return branch is opened for the washing machine in the process of returning to the air conditioner outdoor unit after evaporative heat absorption of the air conditioner indoor unit, so that the washing machine uses the heat exchange amount generated by the refrigeration of the air conditioner to heat the washing water. Based on the sensing of the distribution of human individuals in the room, the real-time working conditions of the air conditioner and the washing machine are coordinated and controlled to selectively use all or part of the refrigerant returned to the outdoor unit of the air conditioner in the refrigeration to raise the washing water temperature of the washing machine. The heat released by the outdoor unit as a condenser can be applied to the washing machine, which not only avoids the consumption of additional electric energy by the washing machine itself to perform the washing task, but also reduces the waste of heat energy of the air conditioner, optimizes the control performance of the air conditioner and the user experience.

[0167] On the basis of any of the above embodiments, the main system pipeline 530 comprises a refrigerant reversing valve.

[0168] The air conditioner indoor unit 510 communicates with the washing machine 521 and / or the air conditioner outdoor unit 522 through the refrigerant reversing valve.

[0169] The refrigerant reversing valve is used for adjusting the flow of the first refrigerant transmission path and the second refrigerant transmission path based on the indoor set temperature and the outdoor coil temperature collected by the sensing module on the air conditioner outdoor unit 522.

[0170] The indoor set temperature is the temperature set when the working mode is activated; the first refrigerant transmission path is used for connecting the refrigerant transmission between the air conditioner indoor unit and the air conditioner outdoor unit; and the second refrigerant transmission path is used for connecting the refrigerant transmission between the air conditioner indoor unit and the washing machine.

[0171] Specifically, the air conditioner and the washing machine 521 are connected through a refrigerant reversing valve, which has a port connected to the refrigerant input pipeline and the refrigerant output pipeline of the washing machine 521 in addition to the ports connected to the refrigerant input pipeline and the refrigerant output pipeline of the air conditioner outdoor unit 522 and the refrigerant input pipeline and the refrigerant output pipeline of the air conditioner indoor unit 510, so as to form two closed paths about the washing machine 521 and the air conditioner outdoor unit 522 connected in parallel.

[0172] If it is determined that the air conditioner has executed the refrigeration mode and the washing machine has started the washing program, the port of the refrigerant reversing valve connected to 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 is opened 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 performed to realize refrigeration.

[0173] Meanwhile, the port of the refrigerant reversing valve connected to the refrigerant input pipeline of the washing machine is opened to form a second refrigerant transmission path of “air conditioner outdoor unit-air conditioner indoor unit-washing machine-air conditioner outdoor unit”, and then part of the heat of the air conditioner indoor unit backflow to the air conditioner outdoor unit is diverted to the washing machine to heat the washing water.

[0174] When it is determined that the air conditioner operates in the refrigeration mode and the washing machine has started the washing program, the flow of the first refrigerant transmission path and the second refrigerant transmission path is adjusted according to the indoor set temperature set on the air conditioner indoor unit and the outdoor coil temperature fed back by the air conditioner outdoor unit after the first refrigerant transmission path and the second refrigerant transmission path are opened. The refrigerant transmission flow of the air conditioner indoor unit when it is connected to the parallel washing machine and the air conditioner outdoor unit can be adaptively adjusted according to the case that the washing machine is also in the working state when the air conditioner is in the refrigeration mode, so as to apply as much as possible the excess heat to the washing machine to heat the washing water under the premise of ensuring the refrigeration capacity of the air conditioner, avoid the over-compression or under-compression of the air conditioner outdoor unit in the sharing process to cause poor refrigeration effect, and optimize the control performance and user experience of the air conditioner.
