AI Technical Summary
In multi-room ducted split air conditioning systems, when there are inconsistent sterilization requirements in different rooms, existing technologies struggle to maintain the temperature requirements of each room while quickly and effectively sterilizing, resulting in some rooms having their temperatures affected.
By adjusting the opening and closing of the air supply valve and return air valve, rooms requiring sterilization are isolated, while cold/heat is stored in rooms without sterilization requirements. At the same time, the total air volume and maximum sterilization time are determined based on the ratio of the number of rooms and temperature requirements to ensure that the temperature requirements of each room are met during the sterilization process.
It achieves the ability to quickly reduce the bacterial concentration in rooms requiring sterilization during the sterilization process, while maintaining the temperature requirements of each room and avoiding temperature fluctuations in rooms without sterilization requirements.

Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of sterilization and temperature control, for example to a multi-room partition sterilization control method, a control device and an intelligent air conditioner. BACKGROUND
[0002] At present, in North American countries such as the United States and Canada, a duct type split air conditioner is used to cool or heat the indoor. The duct type split air conditioner is composed of an outdoor unit, an indoor unit and a connecting pipe. Cold / heat air generated by the indoor unit in the refrigeration / heat mode first enters a main air supply pipe and then is distributed to each branch air supply pipe, and finally enters each room through the air inlet at the end of the branch air supply pipe. Meanwhile, a return air inlet is arranged in each room, and a corresponding return air pipe branch is arranged at the return air inlet. The air in the room is converged to the main return air pipe through the return air pipe branch and then enters the indoor unit.
[0003] Some air conditioners have sterilization function, which can detect the bacterial concentration at the air outlet and / or return air inlet of the air conditioner, and control the air conditioner to enter the sterilization mode to realize indoor sterilization when the room has sterilization demand.
[0004] In the implementation process of the embodiments of the present application, it is found that at least the following problems exist in the related art:
[0005] In the application scenario of the duct type split air conditioner, the number of rooms is multiple, some rooms have sterilization demand, and some rooms have no sterilization demand. If sterilization is performed on the basis of the conventional temperature control scheme, the sterilization rate in the room is likely to be slow. If only the temperature demand and sterilization demand in the room with sterilization demand are considered, the temperature in the room without sterilization demand is likely to be greatly affected.
[0006] It should be noted that the information disclosed in the above background section is only used to strengthen the understanding of the background of the present application, and therefore can include information that does not constitute prior art known to those of ordinary skill in the art. SUMMARY
[0007] To have a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not a general review, nor is it intended to determine key / important elements or delineate the scope of protection of these embodiments, but as a prelude to the detailed description below.
[0008] The embodiments of the present application provide a multi-room partition sterilization control method, a control device and an intelligent air conditioner, so that the rooms with sterilization demand can be sterilized faster while maintaining the temperature demand of each room.
[0009] In some embodiments, the multiple rooms are provided with cold / heat by an air conditioner; the multiple rooms are purified of bacteria in air by a sterilization device; the air conditioner and the sterilization device supply air to each room through air supply pipelines and absorb air from each room through air return pipelines; each room is provided with an air outlet and an air return; the first room has a sterilization requirement, and the second room has no sterilization requirement; and the control method for zoned sterilization of the multiple rooms comprises:
[0010] According to the first temperature requirement of the first room and the quantity ratio between the second room and the first room, a total air volume positively related to the first temperature requirement and positively related to the quantity ratio is determined;
[0011] According to the total air volume and the quantity ratio, a maximum sterilization duration negatively related to the total air volume and negatively related to the quantity ratio is determined;
[0012] The air outlet and the air return of each room are adjusted to isolate the first room, and cold / heat is accumulated in the second room according to the second temperature requirement of the second room and the maximum sterilization duration, so that the accumulated cold / heat can meet the second temperature requirement within the maximum sterilization duration;
[0013] The air outlet and the air return of the first room are opened, the air outlet of the second room is opened, the air return of the second room is closed, and the air conditioner and the sterilization device are started, and temperature adjustment and sterilization operation are performed on the first room within the maximum sterilization duration according to the total air volume.
[0014] The control method for zoned sterilization of the multiple rooms provided by the embodiments can achieve the following technical effects:
[0015] The greater the quantity ratio between the second room and the first room, the more air is taken away from the first room during sterilization of the first room, and the total air volume positively related to the first temperature requirement and positively related to the quantity ratio is determined, so that the air volume of the first room can meet the first temperature requirement of the first room as much as possible during sterilization of the first room.
[0016] However, there is a certain gap between the rooms, and during sterilization, the air outlet valve of the second room is opened, the air return valve is closed, the air outlet valve and the air return valve of the first room are both opened, and the pressure in the second room is higher than that in the first room, which causes the air in the second room to flow to the first room through the gap between the rooms during sterilization. For the first room, the air volume of the air outlet is conducive to meeting the first temperature requirement of the first room, and the inflow of air from the second room to the first room is not conducive to meeting the first temperature requirement of the first room. The more the second room, the greater the total air volume, and the greater the amount of air flowing from the second room to the first room, which is more detrimental to meeting the first temperature requirement of the first room. The maximum sterilization duration negatively related to the total air volume and negatively related to the quantity ratio is determined, which is conducive to meeting the first temperature requirement of the first room during sterilization.
[0017] In addition, before sterilizing the first room, the cold / heat is stored in the second room, and during the sterilization of the first room, the air flows from the second room to the first room, which also causes the stored cold / heat in the second room to gradually flow out. The stored cold / heat in the second room is related to the second temperature requirement and the maximum sterilization duration. If the stored cold / heat cannot meet the second temperature requirement within the maximum sterilization duration, it is obvious that the stored cold / heat in the second room should be positively related to the second temperature requirement and the maximum sterilization duration.
[0018] In this way, during the temperature adjustment and sterilization of the first room by the air conditioner and the sterilization device within the maximum sterilization duration, the first room and the second room can meet their respective temperature requirements.
[0019] During the sterilization of the first room, the air outlet valve of the second room is opened and the air return valve is closed, which causes the air in the second room to flow into the first room through the gap between the two. In this way, the total amount of air flowing into the first room includes two paths: the air outlet amount of the air outlet of the first room, and the air amount flowing from the second room into the first room. Moreover, the total air amount is determined according to the first temperature requirement of the first room and the quantity ratio. Compared with determining the total air amount only according to the first temperature requirement of the first room, the total air amount determined in this way is relatively large. After the relatively large total air amount converges in the first room in two ways, it returns to the air return pipeline through the air return valve of the first room. In this way, the air in the first room can be updated at a relatively fast speed, and the bacterial concentration in the first room can be reduced relatively quickly.
[0020] For a given application scenario, the greater the quantity ratio of the second room to the first room, the fewer the number of first rooms that have sterilization requirements. In the case where the first temperature requirement of the first room remains unchanged, the greater the quantity ratio, the shorter the first duration. Moreover, the greater the quantity ratio, the greater the total air amount, and the greater the air amount flowing from the second room into the first room, which is more conducive to quickly updating the air in the first room and quickly reducing the bacterial concentration in the first room. This makes the bacterial reduction rate of the first room consistent with the maximum sterilization duration to some extent, which is conducive to completing the sterilization operation of the first room within the maximum sterilization duration.
[0021] In this way, the rooms that have sterilization requirements can be sterilized relatively quickly.
[0022] Through the above-mentioned manner, the technical scheme provided by the embodiments of the present application can maintain the temperature requirements of the rooms while sterilizing the rooms that have sterilization requirements relatively quickly.
[0023] Optionally, determining the total air volume positively correlated with the first temperature demand and positively correlated with the quantity ratio comprises: obtaining a first temperature difference between the indoor temperature of the first room and the set temperature; and determining the total air volume positively correlated with the first temperature difference and positively correlated with the quantity ratio. The first temperature demand of the first room is represented by the first temperature difference, and then the total air volume is obtained.
[0024] Optionally, determining the total air volume positively correlated with the first temperature demand and positively correlated with the quantity ratio comprises: obtaining a first temperature difference between the indoor temperature of the first room and the set temperature; and determining the total air volume positively correlated with the first temperature difference and positively correlated with the quantity ratio. The first temperature demand of the first room is represented by the first temperature difference, and then the total air volume is obtained.
[0025] Optionally, increasing the demand air volume according to the quantity ratio to obtain the total air volume comprises: increasing the demand air volume in a linear or exponential form according to the quantity ratio to obtain the total air volume. Correspondingly, determining the maximum sterilization duration according to the total air volume and the quantity ratio comprises: obtaining an air volume difference between the total air volume and the demand air volume; and determining the maximum sterilization duration negatively correlated with the air volume difference.
[0026] The air volume difference between the total air volume and the demand air volume is the air volume flowing into the second room through the air inlet of the second room in the sterilization process, which can also represent the air volume flowing from the second room into the first room. In this way, it can be clearly shown that the maximum sterilization duration is affected by the air volume flowing from the second room into the first room. Of course, the previously described technical solutions can also reflect the source and significance of the maximum sterilization duration.
[0027] Optionally, adjusting the air outlet valve and the return air valve of each room, isolating the first room, and accumulating cold / heat in the second room according to the second temperature demand of the second room and the maximum sterilization duration comprises: closing the air outlet valve and the return air valve of the first room, and opening the air outlet valve and the return air valve of the second room; determining the set cold amount / set heat amount positively correlated with the second temperature difference and positively correlated with the maximum sterilization duration according to the second temperature difference between the indoor temperature of the second room and the set temperature; and controlling the air conditioner to accumulate cold / heat in the second room according to the set cold amount / set heat amount.
[0028] This technical solution can make the cold / heat of the second room continue to be adapted to the maximum sterilization duration and the second temperature demand, which is beneficial to meeting the second temperature demand in the second room during the sterilization process.
[0029] Optionally, the air conditioner and the sterilization device are simultaneously started to perform sterilization operation on the first room within the maximum sterilization duration, including: obtaining the bacteria concentration of the first room, and recording the continuous sterilization duration of the first room; in the case that the continuous sterilization duration is less than or equal to the maximum sterilization duration, and the bacteria concentration is less than the concentration threshold, the sterilization mode is exited; in the case that the continuous sterilization duration is greater than the maximum sterilization duration, and the bacteria concentration is greater than or equal to the concentration threshold, the total air volume, the maximum sterilization duration, the accumulation of cold / heat to the second room are re-determined, and the sterilization operation is performed on the first room.
[0030] After the technical scheme is adopted, the adverse effects of the first room and the second room meeting their respective temperature requirements caused by being in the sterilization state all the time can be reduced or avoided, and the first room and the second room meeting their respective temperature requirements can be facilitated.
[0031] Optionally, the air conditioner is started to perform temperature adjustment operation on the first room within the maximum sterilization duration, including: obtaining the set temperature of the first room; in the case of refrigeration, the temperature difference between the set temperature of the first room and the outlet air temperature of the first room is controlled to be the first temperature threshold by controlling the compressor frequency of the air conditioner.
[0032] The technical scheme can make the first room meet the first temperature requirement in the first sterilization process.
[0033] Optionally, the air conditioner is started to perform temperature adjustment operation on the first room within the maximum sterilization duration, including: obtaining the set temperature of the first room; in the case of heating, the temperature difference between the outlet air temperature of the first room and the set temperature of the first room is controlled to be the second temperature threshold by controlling the compressor frequency of the air conditioner.
[0034] The technical scheme can make the first room meet the first temperature requirement in the first sterilization process.
[0035] Optionally, the control method of multi-room partition sterilization further includes: counting the sterilization frequency of each room within a set duration; determining the fresh air frequency positively correlated with the sterilization frequency; and introducing fresh air into each room according to the fresh air frequency.
[0036] In this way, fresh air can be introduced in a targeted manner to reduce the occurrence of rooms with sterilization requirements in the form of fresh air.
[0037] Optionally, the control method of multi-room partition sterilization further includes: determining the room cleanliness level negatively correlated with the bacteria concentration of each room, and displaying the cleanliness level of each room to realize the visualization of the cleanliness level.
[0038] In some embodiments, the plurality of rooms are provided with cold / heat by an air conditioner; the plurality of rooms are provided with sterilization by a sterilization device; the air conditioner and the sterilization device supply air to each room through a supply air pipeline and absorb air from each room through a return air pipeline; each room is provided with an air outlet and an air return; the air outlet is provided with an air outlet valve, and the air return is provided with an air return valve; the first room has a sterilization requirement, and the second room has no sterilization requirement; the control device for the plurality of rooms to be sterilized in a partitioned manner comprises a first determination module, a second determination module, a first control module, and a second control module;
[0039] The first determination module is configured to determine a total air volume that is positively correlated with the first temperature requirement and positively correlated with the quantity ratio between the second room and the first room;
[0040] The second determination module is configured to determine a maximum sterilization duration that is negatively correlated with the total air volume and negatively correlated with the quantity ratio;

[0057] In order to enable a more detailed understanding of the features and technical content of the embodiments of the present application, the implementation of the embodiments of the present application is described in detail below with reference to the accompanying drawings, which are only used for reference and do not limit the embodiments of the present application. In the following technical description, in order to facilitate explanation, a plurality of details are provided to provide a full understanding of the disclosed embodiments. However, one or more embodiments can still be implemented without these details. In other cases, well-known structures and devices can be simplified to facilitate the drawings.
[0058] The terms "first", "second", and the like in the specification and claims of the embodiments of the present application and the above-described drawings are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the embodiments of the present application described herein can be implemented. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion.
[0059] Unless otherwise specified, the term "a plurality of" means two or more.
[0060] In this embodiment, the character " / " indicates that the objects before and after it are in an "or" relationship. For example, A / B means: A or B.
[0061] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.
[0062] Figure 1 This is a schematic diagram of an implementation scenario of a ducted split air conditioner provided in an embodiment of this application.
[0063] Combination Figure 1 As shown, the indoor unit 11 of the air conditioner is usually installed in an indoor space, and is usually concealed, for example, it can be installed in the indoor ceiling 14, which can save the machine room area.
[0064] The indoor unit 11 of the air conditioner is connected to other rooms 15 without an indoor unit 11 through the air supply duct 12. After the air undergoes heat exchange in the indoor unit 11, it enters each room 15 through the air supply duct 12. An air valve is installed at the end of the air supply duct 12 in each room 15. By adjusting the opening of the air valve, the air volume entering the room 15 can be adjusted, thereby adjusting the indoor temperature.
[0065] The indoor unit 11 of the air conditioner absorbs air from each room 15 through the return air duct 13, and the air in the return air duct 13 and the supply air duct 12 exchange heat inside the indoor unit 11.
[0066] The cooling / heating principle of the ducted split air conditioner is similar to that of the ordinary split air conditioner. It consists of an indoor unit 11 and an outdoor unit (not shown in the figure), which are connected by copper pipes during installation.
[0067] The static pressure at the air outlet of the indoor unit 11 of a ducted split air conditioner is higher than that at the air outlet of the indoor unit of a regular split air conditioner; the single unit capacity of a ducted split air conditioner is also relatively large, generally available in various specifications such as 5 horsepower, 8 horsepower, 10 horsepower, and 12.5 horsepower; the length of the copper pipe that can be connected between the indoor unit 11 and the outdoor unit of a ducted split air conditioner is also longer, generally up to 50m, and the height difference between the indoor and outdoor units can reach 20m.
[0068] The sterilization device 16 shares an air duct with the indoor unit 11 of the air conditioner, and the sterilization device 16 can be installed at the air outlet of the indoor unit 11 of the air conditioner.
[0069] The sterilization principle employed by the aforementioned sterilization device 16 includes, but is not limited to, water ions, ultraviolet (UV) light, and negative oxygen ions.
[0070] In this application embodiment, the term "air volume" refers to airflow rate, which is used to represent the amount of air circulating per unit time, and its unit can be m³ / s. 3 / h、m 3 / min, L / h, L / min, etc.
[0071] In the embodiments of this application, the performance of the air valve meets the requirements, specifically: when the air valve is closed, the air valve meets the common air-leakage judgment criteria in the field, and the impact of air leakage from the air valve can be disregarded.
[0072] In this application embodiment, only the implementation scenario of a ducted split air conditioner is used as an example for illustration. Other scenarios similar to this implementation scenario, such as the application scenario of central air conditioning, can also adopt this multi-room zone air purification control method, which will not be described in detail here.
[0073] Figure 2 This is a flowchart illustrating a multi-room zone sterilization control method provided in an embodiment of this application. This multi-room zone sterilization control method can be executed in the air conditioner controller, or, in a smart home scenario, it can also be executed on the server of the smart home system.
[0074] Multiple rooms are provided with cooling / heating by one air conditioner; multiple rooms are purified of bacteria in the air by one sterilization device; the air conditioner and sterilization device supply air to each room through the air supply duct and absorb air from each room through the return air duct; each room is equipped with an air outlet and a return air outlet, with an air outlet valve and a return air valve; the first room has sterilization requirements, while the second room does not.
[0075] For example, if the bacterial concentration in the first room is greater than or equal to a concentration threshold, the first room has a need for sterilization; if the bacterial concentration in the second room is less than the concentration threshold, the second room does not have a need for sterilization.
[0076] When there are multiple first rooms, the bacterial concentration in each first room is decreasing, and the bacterial concentration and the rate of decrease in each first room are not necessarily the same. If the bacterial concentration in a first room changes from being greater than or equal to the concentration threshold to being less than the concentration threshold, then the first room will be switched to the second room.
[0077] Combination Figure 2 As shown, the control method for multi-room zoned sterilization includes:
[0078] S201. Based on the first temperature requirement of the first room and the ratio of the number of the second room to the first room, determine the total air volume that is positively correlated with the first temperature requirement and the ratio of the number of rooms.
[0079] Temperature demand is the desired temperature state, and the need to raise or lower the room temperature in order to achieve this desired temperature state.
[0080] For example, in cooling mode, if the indoor temperature is higher than the set temperature, the room needs to be cooled down; if the indoor temperature is stable at the set temperature, the room needs to be kept at a stable temperature.
[0081] Correspondingly, in heating mode, if the indoor temperature is lower than the set temperature, the room needs to be heated; if the indoor temperature is stable at the set temperature, the room needs to be kept at a stable temperature.
[0082] The aforementioned first temperature requirement specifically refers to the temperature requirement in the first room. In the embodiments of this application, there are one or more first rooms, and each first room corresponds to a first temperature requirement.
[0083] The second temperature requirement mentioned below specifically refers to the temperature requirement in the second room. In the embodiments of this application, there are one or more second rooms, and each second room corresponds to a second temperature requirement.
[0084] When there is only one first room, the total air volume positively correlated with the first temperature requirement refers to the total air volume positively correlated with the first temperature requirement of that single first room. When there are multiple first rooms, the total air volume positively correlated with the first temperature requirement refers to the total air volume positively correlated with the sum of the first temperature requirements of the multiple first rooms. This corresponds to the function of the total air volume in subsequent steps to meet the first temperature requirement of the first room.
[0085] For any given application scenario, the total number of rooms is a fixed value. At any given moment, after detecting the bacterial concentration in each room and dividing the rooms into first and second rooms, the number of first rooms and the number of second rooms are both available values.
[0086] The relationship between the primary temperature requirement, the quantity ratio, and the total air volume can be obtained through experimentation or modeling. Whether obtained through experimentation or modeling, the air volume supplied to the primary room must, based on the set total air volume, meet the primary temperature requirement of the primary room.
[0087] The first temperature requirement can be represented by a first temperature difference between the actual temperature of the first room and the set temperature. Thus, determining the total air volume, which is positively correlated with the first temperature requirement and with the quantity ratio, can include: obtaining the first temperature difference between the indoor temperature of the first room and the set temperature; and determining the total air volume, which is positively correlated with the first temperature difference and with the quantity ratio. The first temperature requirement of the first room is represented by the first temperature difference, thereby obtaining the total air volume.
[0088] Alternatively, determining the total airflow that is positively correlated with both the first temperature requirement and the quantity ratio can include: obtaining the first temperature difference between the indoor temperature of the first room and the set temperature; determining the required airflow that is positively correlated with the first temperature difference; and increasing the required airflow according to the quantity ratio to obtain the total airflow. Representing the first temperature requirement of the first room by the first temperature difference clearly shows the role of the total airflow: to meet the first temperature requirement of the first room. Of course, based on the correspondence between the first temperature requirement, the quantity ratio, and the total airflow obtained through experimentation or modeling, the total airflow can also meet the first temperature requirement of the first room.
[0089] S202. Based on the total air volume and the quantity ratio, determine the maximum sterilization time that is negatively correlated with both the total air volume and the quantity ratio.
[0090] The relationship between total air volume, quantity ratio, and maximum sterilization time can be obtained through experimentation or modeling. Regardless of whether it is obtained experimentally or through modeling, it must be ensured that: within the maximum sterilization time, the measured temperature change in the first room during the experiment is less than or equal to a pre-set third temperature threshold, or the expected temperature change predicted in the modeling of the first room is less than or equal to the pre-set third temperature threshold; and the measured temperature change in the second room during the experiment is less than or equal to a pre-set fourth temperature threshold, or the expected temperature change predicted in the modeling of the second room is less than or equal to the pre-set fourth temperature threshold.
[0091] The third temperature threshold is used to determine whether the temperature change in the first room meets the first temperature requirement during the sterilization process. If the temperature change in the first room is less than or equal to the third temperature threshold, it means that the sterilization process can meet the first temperature requirement of the first room.
[0092] Multiple first rooms can share a single third temperature threshold, or different first rooms can have different third temperature thresholds.
[0093] The fourth temperature threshold is used to determine whether the temperature of the second room meets the standard for meeting the second temperature requirement during the sterilization process. If the temperature change of the second room is less than or equal to the fourth temperature threshold, it means that the second temperature requirement of the second room can be met during the sterilization process.
[0094] Multiple second rooms can share a single fourth temperature threshold, or different second rooms can have different fourth temperature thresholds.
[0095] Those skilled in the art can set the aforementioned third and fourth temperature thresholds accordingly to meet the actual requirements for room temperature, which will not be elaborated here.
[0096] S203. Adjust the air supply and return valves of each room to isolate the first room, and at the same time, accumulate cold / heat in the second room according to the second room's second temperature requirement and the maximum sterilization time.
[0097] Isolating the first room refers to closing the air supply and return valves of the first room; accumulating cold / heat in the second room refers to opening the air supply and return valves of the second room. In cooling mode, cooler air is blown into the second room and warmer air is expelled from the second room; in heating mode, warmer air is blown into the second room and cooler air is expelled from the second room.
[0098] In this scenario, cooling / heating is continuously supplied to the second room based on its secondary temperature requirement and the maximum sterilization duration. The accumulated cooling / heating must be sufficient to meet the secondary temperature requirement within the maximum sterilization duration. Typically, the accumulated cooling / heating in the second room is positively correlated with both the secondary temperature requirement and the maximum sterilization duration.
[0099] In setting the maximum sterilization time in the aforementioned S202, the need to ensure that the second room can still meet the second temperature requirement during the sterilization process has been taken into consideration. The more cold / heat energy is accumulated in the second room, the easier it is to ensure that the second room meets the second temperature requirement within the maximum sterilization time.
[0100] If too much cold / heat is accumulated, the time required to accumulate cold / heat will be prolonged, or the air outlet temperature during the accumulation process will easily cause discomfort.
[0101] Those skilled in the art can comprehensively consider the actual situation of the process of accumulating cold / heat, and combine it with the aforementioned specific requirements for ensuring that the second room meets the second temperature requirement during the sterilization process (within the maximum sterilization time), and finally set the specific amount and method of accumulating cold / heat in the second room in S203.
[0102] The second temperature requirement can be represented by the second temperature difference between the indoor temperature of the second room and the set temperature. Thus, simultaneously accumulating cooling / heat in the second room based on the second temperature requirement and the maximum sterilization duration can include: accumulating a total cooling / heat in the second room that is positively correlated with the maximum sterilization duration and the second temperature difference, based on the maximum sterilization duration and the second temperature difference between the indoor temperature of the second room and the set temperature.
[0103] Alternatively, based on the second room's second temperature requirement and the maximum sterilization duration, the system may simultaneously store cooling / heat in the second room, which may include: determining a set cooling / heat that is positively correlated with the second temperature difference and the maximum sterilization duration based on the second temperature difference between the room's indoor temperature and the set temperature; and controlling the air conditioner to store cooling / heat in the second room based on the set cooling / heat.
[0104] This technical solution enables the continued cooling / heating of the second room to be matched with the maximum sterilization time and the second temperature requirement, which is beneficial to meeting the second temperature requirement in the second room during the sterilization process.
[0105] S204. Open the air supply valve and return air valve of the first room, open the air supply valve of the second room, close the return air valve of the second room, and simultaneously start the air conditioner and sterilization device. Adjust the temperature and perform sterilization operations in the first room according to the total air volume within the maximum sterilization time.
[0106] Total air volume is used to control the indoor fan speed of the air conditioner. When multiple rooms share one air conditioner, with the opening degree of the air supply valve and return air valve in each room remaining unchanged, the larger the total air volume, the larger the air volume of the air outlet in each room.
[0107] The multi-room zoned sterilization control method provided in this application embodiment can achieve the following technical effects:
[0108] The larger the ratio of the number of second rooms to the number of first rooms, the more air volume is diverted from the second room during the sterilization process in the first room. Determining the total air volume, which is positively correlated with the first temperature requirement and the ratio of the number of rooms, ensures that the air volume output from the first room meets the first temperature requirement of the first room as much as possible during the sterilization process in the first room.
[0109] However, there are gaps between the rooms. During sterilization, the air outlet valve of the second room is open and the return air valve is closed, while both the air outlet valve and return air valve of the first room are open. The pressure in the second room is higher than that in the first room. This causes air from the second room to easily flow into the first room through the gaps between the rooms during sterilization. For the first room, the airflow from the outlet is beneficial to meeting the first room's primary temperature requirement, while the airflow from the second room into the first room is detrimental to meeting this requirement. The more second rooms there are, the larger the total airflow, and the greater the amount of air flowing from the second room into the first room, which is even more detrimental to meeting the first room's primary temperature requirement. Determining a maximum sterilization time that is negatively correlated with both the total airflow and the ratio of the number of rooms is beneficial for meeting the first room's primary temperature requirement during sterilization.
[0110] On another front, before sterilizing the first room, cold / heat is stored in the second room. During the sterilization process of the first room, air flows from the second room into the first room, which causes the cold / heat stored in the second room to gradually dissipate. The cold / heat stored in the second room is related to the second temperature requirement and the maximum sterilization time. To achieve the goal of meeting the second temperature requirement within the maximum sterilization time, the cold / heat stored in the second room obviously needs to be positively correlated with the second temperature requirement and the maximum sterilization time.
[0111] In this way, during the process of activating the air conditioner and sterilization device to adjust the temperature of the first room and perform sterilization within the maximum sterilization time, both the first room and the second room can meet their respective temperature requirements.
[0112] During the sterilization process in the first room, the air outlet valve of the second room is opened and the return air valve is closed. This allows air from the second room to flow into the first room through the gap between the two. Thus, the total amount of air flowing into the first room includes two pathways: the air volume from the air outlet of the first room and the air volume flowing into the first room from the second room. Furthermore, the total air volume is determined based on the first room's temperature requirement and quantity ratio. Compared to determining the total air volume solely based on the first room's temperature requirement, this method results in a relatively larger total air volume. This larger total air volume, after converging into the first room in both ways, returns to the return air duct through the first room's return air valve. This allows for faster air renewal in the first room and a more rapid reduction in bacterial concentration.
[0113] For a given application scenario, a larger ratio of the number of second rooms to the number of first rooms indicates a smaller number of first rooms requiring sterilization. With the initial temperature requirement of the first room remaining constant, a larger ratio results in a shorter initial sterilization time. Furthermore, a larger ratio also means a larger total airflow, resulting in a greater amount of air flowing from the second room into the first room. This facilitates faster air renewal in the first room and a faster reduction in bacterial concentration. This causes the rate of bacterial reduction in the first room to show a certain consistency with the maximum sterilization time, which is beneficial for completing the sterilization operation in the first room within the maximum sterilization time.
[0114] This allows for faster sterilization of rooms that require sterilization.
[0115] Through the above methods, the technical solution provided in this application embodiment can maintain the temperature requirements of each room while also quickly sterilizing rooms that require sterilization.
[0116] The following section will further explain the process of controlling the air conditioner to adjust the temperature of the first room.
[0117] During this process, the target was the first room.
[0118] In addition to controlling the total air volume, it is also necessary to control the air outlet temperature of the first room, which means that the frequency of the air conditioning compressor needs to be controlled.
[0119] In controlling the air conditioner compressor to control the air outlet temperature of the first room, the air outlet temperature of the first room can be determined based on a first temperature difference between the actual temperature of the first room and the set temperature. For example, in cooling mode, the larger the first temperature difference, the lower the air outlet temperature; in heating mode, the larger the first temperature difference, the higher the air outlet temperature.
[0120] The frequency of the air conditioner compressor is then controlled based on the outlet air temperature. For example, in cooling mode, the lower the outlet air temperature, the higher the air conditioner compressor frequency; in heating mode, the higher the outlet air temperature, the higher the air conditioner compressor frequency.
[0121] Alternatively, the air conditioner can be activated to adjust the temperature of the first room during the maximum sterilization period, which may include: obtaining the set temperature of the first room; and, in cooling mode, controlling the frequency of the air conditioner compressor so that the temperature difference between the set temperature of the first room and the air outlet temperature of the first room is a first temperature threshold.
[0122] Corresponding to the heating mode, starting the air conditioner to adjust the temperature of the first room within the maximum sterilization time may include: obtaining the set temperature of the first room; and, in the heating mode, controlling the frequency of the air conditioner compressor so that the temperature difference between the air outlet temperature of the first room and the set temperature of the first room is a second temperature threshold.
[0123] This technical solution enables the first room to meet the first temperature requirement during the first sterilization process.
[0124] Generally, the larger the initial temperature difference, the higher the operating frequency of the air conditioner compressor, for example, the classic Proportional-Integral-Differential (PID) control algorithm. In this embodiment, by setting the first and second temperature thresholds according to the above scheme, the outlet air temperature of the first room can be kept relatively stable. During the sterilization process of the first room, this relatively stable outlet air temperature is beneficial for predicting the temperature changes of the first and second rooms. Based on such a relatively stable outlet air temperature, it is beneficial to calculate a more accurate maximum sterilization time in S202 and to accumulate a more accurate amount of cooling / heating energy in the second room in S203. Ultimately, during the sterilization process of the first room, it makes it easier for both the first and second rooms to meet their respective temperature requirements.
[0125] Figure 3This is a flowchart illustrating a multi-room zone sterilization control method provided in an embodiment of this application. This multi-room zone sterilization control method can be executed in the air conditioner controller, or, in a smart home scenario, it can also be executed on the server of the smart home system.
[0126] Multiple rooms are provided with cooling / heating by one air conditioner; multiple rooms are purified of bacteria in the air by one sterilization device; the air conditioner and sterilization device supply air to each room through the air supply duct and absorb air from each room through the return air duct; each room is equipped with an air outlet and a return air outlet, with an air outlet valve and a return air valve; the first room has sterilization requirements, while the second room does not.
[0127] Combination Figure 3 As shown, the control method for multi-room zoned sterilization includes:
[0128] S301. Obtain the first temperature difference between the indoor temperature of the first room and the set temperature.
[0129] S302. Determine the required air volume that is positively correlated with the first temperature difference.
[0130] S303. Increase the required air volume in a linear or exponential manner according to the quantity ratio to obtain the total air volume.
[0131] This step makes the increase in demand air volume positively correlated with the demand air volume itself.
[0132] For example, the quantity ratio can be mapped to an increase factor greater than 1, and the total air volume can be determined by multiplying the demand air volume by the increase factor; or, the total air volume can be determined by raising the demand air volume to the power of the increase factor.
[0133] Specifically, the product or power can be used as the total air volume, and the product or power can be adjusted by increasing or decreasing, with the adjusted value used as the total air volume.
[0134] S304. Obtain the air volume difference between the total air volume and the required air volume.
[0135] S305. Determine the maximum sterilization duration that is negatively correlated with the air volume difference.
[0136] S306. Adjust the air supply and return valves of each room to isolate the first room, and at the same time, accumulate cold / heat in the second room according to the second room's second temperature requirement and the maximum sterilization time.
[0137] This step ensures that the accumulated cooling / heat can meet the secondary temperature requirement within the maximum sterilization time. Typically, the accumulated cooling / heat in the secondary room is positively correlated with both the secondary temperature requirement and the maximum sterilization time.
[0138] S307. Open the air supply valve and return air valve of the first room, open the air supply valve of the second room, close the return air valve of the second room, and simultaneously start the air conditioner and sterilization device. Adjust the temperature and perform sterilization operations in the first room according to the total air volume within the maximum sterilization time.
[0139] The difference between the total air volume and the required air volume represents the amount of air flowing into the second room through the air inlet during the sterilization process, or the amount of air flowing from the second room into the first room. This clearly demonstrates that the maximum sterilization time is affected by the amount of air flowing from the second room into the first room. Of course, the previously described technical solution also illustrates the source of the maximum sterilization time and its role in the embodiments of this application.

This multi-room zone sterilization control method can be executed in the air conditioner controller, or, in a smart home scenario, it can also be executed on the server of the smart home system.

[0142] S401. Based on the first temperature requirement of the first room and the ratio of the number of the second room to the first room, determine the total air volume that is positively correlated with the first temperature requirement and the ratio of the number of rooms.
[0143] S402. Based on the total air volume and the quantity ratio, determine the maximum sterilization time that is negatively correlated with both the total air volume and the quantity ratio.
[0144] S403. Adjust the air supply and return valves of each room to isolate the first room, and at the same time, accumulate cold / heat in the second room according to the second room's second temperature requirement and the maximum sterilization time.
[0145] This step ensures that the accumulated cold / heat can meet the second temperature requirement within the maximum sterilization time.
[0146] S404. Open the air supply valve and return air valve of the first room, open the air supply valve of the second room, close the return air valve of the second room, and simultaneously start the air conditioner and sterilization device. Adjust the temperature and perform sterilization operations in the first room according to the total air volume within the maximum sterilization time.
[0147] S405. Obtain the bacterial concentration in the first room and record the duration of continuous sterilization in the first room.
[0148] S406. If the continuous sterilization duration is greater than the maximum sterilization duration and the bacterial concentration is greater than or equal to the concentration threshold, execute S401.
[0149] S407. If the continuous sterilization duration is less than or equal to the maximum sterilization duration and the bacterial concentration is less than the concentration threshold, exit the sterilization mode.
[0150] By adopting this technical solution, the adverse effects of being constantly in a sterilization state on the first and second rooms meeting their respective temperature requirements can be reduced or avoided, which is conducive to ensuring that the first and second rooms meet their respective temperature requirements.
[0151] In some feasible embodiments, the multi-room zone sterilization control method further includes: statistically analyzing the sterilization frequency of each room within a set time period; determining the fresh air frequency that is positively correlated with the sterilization frequency; and supplying fresh air to each room according to the fresh air frequency.
[0152] Thus, the multi-room zoned sterilization control method provided in the aforementioned embodiments, combined with the fresh air control scheme, can achieve targeted fresh air ventilation, thereby reducing the number of rooms requiring sterilization.
[0153] In some feasible embodiments, the multi-room zoned sterilization control method further includes: determining the room cleanliness level that is negatively correlated with the bacterial concentration in each room, and displaying the cleanliness level of each room to achieve cleanliness level visualization.
[0154] A higher cleanliness level indicates that the air in the room is more conducive to health. Including bacterial concentration in the cleanliness level provides a more intuitive view of the bacterial situation in the room.
