[0029] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions of the present application are further elaborated in detail below in conjunction with the drawings and embodiments. The described embodiments should not be regarded as limiting the present application. All other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0030] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0031] The terms "first / second / third" involved in the present application are merely used to distinguish similar objects and do not represent a specific ordering of the objects. It can be understood that "first / second / third" can be interchanged with a specific order or sequence where permitted, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0033] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] The embodiment of the present application provides a control method for a multi-split fresh air air conditioner, wherein the multi-split fresh air air conditioner includes an outdoor unit and a plurality of indoor units arranged in different independent spaces; Figure 1 As shown, the method comprises the following steps:

[0035] S101: Acquire first information.

[0036] The first information is used to indicate that there is a demand for introducing fresh air into an independent space where at least one first indoor unit among the multiple indoor units is located.

[0037] It is understandable that the multiple indoor units of the air conditioner can be arranged in different spaces. The multiple indoor units can include at least one first indoor unit and at least one second indoor unit, or can include at least one first indoor unit, at least one second indoor unit and other indoor units, which is not specifically limited in this application. Figure 2 and Figure 3 As shown, each indoor unit may include a fan, a fresh air outlet, an indoor air outlet and an outdoor air outlet; a fresh air duct is formed between the outdoor air outlet and the fresh air outlet, and the indoor unit can introduce fresh air through the fan and the fresh air duct; an exhaust air duct is formed between the outdoor air outlet and the indoor air outlet, and the indoor unit can exhaust air through the fan and the exhaust air duct.

[0038] Here, a house with a living room and two rooms is taken as an example, and the two rooms are Room A and Room B respectively; then, an indoor unit can be set up in each of the spaces where the living room, Room A and Room B are located.

[0039] In the embodiment of the present application, the demand for fresh air introduction can be determined by the command received by the indoor unit in the room or by monitoring the air index; the air index may include the indoor carbon dioxide (CO2) concentration and PM2.5 (2.5-micrometer Particulate Matter) concentration. For example: when the CO2 concentration and PM2.5 concentration in room A exceed the standard or receive the fresh air start command, it indicates that room A has a demand for fresh air introduction; when the CO2 concentration and PM2.5 concentration in room A do not exceed the standard or receive the fresh air start command, it indicates that room A does not have a demand for fresh air introduction.

[0040] Each indoor unit can be configured with a separate fresh air module for receiving instructions for the operation of the fresh air function or monitoring the air index. The fresh air module may include various types of sensors, which are not specifically limited in this application.

[0041] The demand for fresh air introduction can include strong fresh air demand and general fresh air demand; if the CO2 concentration and PM2.5 concentration in room A seriously exceed the standard, for example, the CO2 concentration and PM2.5 concentration are higher than the set concentration threshold, it indicates that room A has a strong demand for fresh air. Simply introducing fresh air cannot quickly improve the air quality in room A. Fresh air can be introduced through the indoor unit of room A, and other rooms can be linked to exhaust air, so that the indoor space can quickly form air circulation and reduce the air concentration in room A. General fresh air demand can be understood as the CO2 concentration and PM2.5 concentration in the room exceeding the standard but not higher than the set concentration threshold. The air quality can be improved by introducing fresh air into the room. Strong fresh air demand and general fresh air demand can also be determined by the instructions received by the indoor unit, which will not be elaborated here.

[0042] In an embodiment of the present application, the first information may indicate that at least one room has a general fresh air demand or a strong fresh air demand.

[0043] S102: Acquire second information.

[0044] The second information is used to indicate fresh air demand information of an independent space where at least one second indoor unit among the multiple indoor units is located.

[0045] It is understandable that the fresh air demand information may include the air quality information of the room, and this application does not make specific limitations on this. Exemplarily, the air quality information may include CO2 concentration information and PM2.5 concentration information. For example: when the windows of room A are open, the air in the room is in a natural flow state, and the air quality information shows that the CO2 concentration and PM2.5 concentration are not exceeded, then there is no need to introduce fresh air into the room; when the doors and windows of room A are closed for a long time, the air quality information shows that the CO2 concentration and PM2.5 concentration are exceeded, then there is a need to introduce fresh air into the room.

[0046] In the embodiment of the present application, the second information may indicate air quality information of an independent space where at least one second indoor unit is located.

[0047] S103: According to the first information and the second information, control at least one first indoor unit and at least one second indoor unit to operate in a target working mode.

[0048] It is understandable that the target working mode can be set according to actual conditions, and this application does not make specific limitations on this. Exemplarily, the target working mode may include a fresh air circulation mode and a simple fresh air mode. The fresh air circulation mode can be understood as introducing fresh air into the indoor space while exhausting the dirty air in the indoor space, so that the air circulates. In the case where there are multiple indoor units in the indoor space, some of the indoor units can introduce fresh air and some of the indoor units can exhaust air, so that the indoor air circulates. The simple fresh air mode can be understood as introducing fresh air into the indoor space without exhausting the air.

[0049] In the embodiment of the present application, if the first information indicates that the independent space where at least one first indoor unit is located has a strong demand for fresh air; and the second information indicates that the air quality of the independent space where at least one second indoor unit is located is qualified, that is, the CO2 concentration and PM2.5 concentration are not exceeded, then the air conditioner can be triggered to enter the fresh air circulation mode. The outdoor air is controlled to enter the indoor fresh air from the fresh air duct of the first indoor unit in the space with a strong demand for fresh air, and the indoor air is controlled to be discharged from the exhaust duct of at least one second indoor unit.

[0050] If the first information indicates that the independent space where at least one first indoor unit is located has a general fresh air demand, and the second information indicates that the air quality of the independent space where at least one second indoor unit is located is qualified, the air conditioner can be triggered to enter the simple fresh air mode. The outdoor air is controlled to enter the room from the fresh air duct of the first indoor unit in the space with general fresh air demand, and the indoor air is controlled to be discharged from the exhaust duct of at least one second indoor unit.

[0051] From the above content, it can be seen that the control method of the multi-split fresh air air conditioner provided in the present application obtains the first information and the second information to control at least one first indoor unit and at least one second indoor unit to operate in the target working mode, thereby solving the problem in the related technology that it is impossible to link the indoor units in multiple spaces to realize the intelligent control of the multi-split fresh air air conditioner, making the fresh air function of the multi-split fresh air air conditioner operate more intelligently and improving the air quality.

[0052] In some embodiments of the present application, the target operating mode includes a first operating mode, in which outdoor air is controlled to flow from the outdoor air outlet of at least one first indoor unit through the fresh air duct and then be introduced into the room from the fresh air outlet, and indoor air is controlled to flow from the indoor air outlet of at least one second indoor unit through the exhaust duct and then be discharged to the outdoors from the outdoor air outlet.

[0053] It can be understood that the first working mode can be a fresh air circulation mode, and this application does not make any specific limitation on this.

[0054] In an embodiment of the present application, the air conditioner in the house is in the fresh air circulation mode, which indicates that at least one first indoor space has a strong demand for fresh air. In this mode, the outdoor air can be controlled to enter the room from the fresh air duct of the first indoor unit corresponding to at least one space with a strong demand for fresh air, and the indoor air can be controlled to be discharged from the exhaust duct of the second indoor unit corresponding to at least one space without a demand for fresh air introduction.

[0055] In some embodiments of the present application, if the first information indicates that the independent space where the multiple first indoor units are located has a demand for introducing fresh air, and the second information indicates that the independent space where at least one second indoor unit is located has no demand for introducing fresh air, the multiple first indoor units and at least one second indoor unit are controlled to operate in the first working mode.

[0056] It can be understood that if the first information indicates that the independent space where multiple first indoor units are located has a strong demand for fresh air; the second information indicates that the air quality of the independent space where at least one second indoor unit is located is qualified, that is, the CO2 concentration and the PM2.5 concentration do not exceed the standard, then the air conditioner can be triggered to enter the fresh air circulation mode; and then the outdoor air is controlled to be introduced into the indoor space from the fresh air ducts of the first indoor units corresponding to multiple spaces with strong fresh air demands, and the indoor air is controlled to be discharged from the exhaust ducts of the second indoor unit corresponding to at least one space without fresh air introduction demand.

[0057] In the present application, refer to Figure 4 As shown, both Room 1 and Room 2 have a strong demand for fresh air, and the air conditioner enters the fresh air circulation mode, introducing fresh air through the indoor units of Room 1 and Room 2, and exhausting the dirty air through the living room indoor unit.

[0058] In some embodiments of the present application, in a first operating mode, at least one first indoor unit is controlled to operate for a first period of time, and at least one second indoor unit is controlled to operate for a first period of time; the first period of time is determined based on the amount of fresh air introduced by at least one first indoor unit, the amount of air discharged by at least one second indoor unit, and the spatial volume of the independent space where the multiple indoor units are located.

[0059] It is understandable that the specific value of the first duration can be set according to actual needs, and this application does not make specific limitations on this. For example, the actual need may be the operating time T for restoring indoor air balance.

[0060] In the embodiment of the present application, V is set as the volume of the house space, Q1 is the fresh air volume introduced by at least one first indoor unit, Q2 is the air volume discharged by at least one second indoor unit, and the first time length T=2*V / (Q1+Q2). Figure 4As shown, room 1 and room 2 generate a slight positive pressure due to the introduction of fresh air, and the dirty air will quickly overflow from the door gap. At the same time, due to the synchronous exhaust of the living room indoor unit, a slight negative pressure will be generated. The dirty air will be quickly discharged to the outside through the living room indoor unit under the action of the pressure difference. After reaching the first time T, the indoor air of the entire house will gradually be balanced and remain fresh.

[0061] In some embodiments of the present application, if the first information indicates that an independent space where a first indoor unit is located has a demand for introducing fresh air, and the second information indicates that an independent space where at least one second indoor unit is located has no demand for introducing fresh air, a first indoor unit and the at least one second indoor unit are controlled to operate in the first working mode.

[0062] It can be understood that if the first information indicates that an independent space where a first indoor unit is located has a strong demand for fresh air; the second information indicates that the air quality of at least one independent space where a second indoor unit is located is qualified, that is, the CO2 concentration and the PM2.5 concentration do not exceed the standard, then the air conditioner can be triggered to enter the fresh air circulation mode; and then the outdoor air is controlled to enter the indoor space from the fresh air duct corresponding to the first indoor unit in a space with a strong demand for fresh air, and the indoor air is controlled to be discharged from the exhaust duct of the second indoor unit corresponding to at least one space without the demand for fresh air introduction.

[0063] In the present application, refer to Figure 5 As shown, Room 1 has a strong demand for fresh air, the air conditioner enters the fresh air circulation mode, and the indoor unit of Room 1 is turned on to introduce fresh air. At the same time, the indoor unit of Room 2 can be turned on to exhaust the dirty air, and the indoor unit of the living room can also be turned on to exhaust the dirty air.

[0064] In some embodiments of the present application, the at least one second indoor unit includes a second indoor unit whose distance to a first indoor unit is within a distance threshold.

[0065] It is understandable that the distance threshold can be set according to actual conditions, and this application does not make specific restrictions on this. The indoor unit with fresh air demand introduces fresh air to send the dirty air out through the door gap, and the indoor unit in the space closer to the room can be opened for exhaust to accelerate the flow of air. The distance threshold can be set according to the actual distance between the rooms.

[0066] In the present application, refer to Figure 5As shown, Room 1 has a strong demand for fresh air, the air conditioner enters the fresh air circulation mode, and the indoor unit of Room 1 is turned on to introduce fresh air. The indoor unit of Room 2 can be turned on nearby to exhaust the dirty air. Room 1 generates a slight positive pressure due to the introduction of fresh air, and the dirty air will quickly overflow from the door gap. At the same time, since Room 2 is exhausted simultaneously, a slight negative pressure will be generated. The dirty air will be quickly discharged to the outside through the indoor unit of Room 2 under the action of the pressure difference. Similarly, after a certain period of time, due to the interaction of suction and exhaust, the fresh air will be fully circulated in Room 1 and Room 2, making the indoor air reach a fresh state.

[0067] In some embodiments of the present application, the target operating mode includes a second operating mode, in which the air supply fan is operated to control the outdoor air to flow from the outdoor air outlet of at least one first indoor unit through the fresh air duct and then be introduced into the indoor room from the fresh air outlet, and the indoor air is prohibited from flowing from the indoor air outlet of at least one second indoor unit through the exhaust duct and then being discharged to the outdoors from the outdoor air outlet.

[0068] It can be understood that the second working mode can be a simple fresh air mode, and this application does not make any specific limitation on this.

[0069] In an embodiment of the present application, the air conditioner in the house is in a simple fresh air mode, which indicates that at least one first indoor space has a general fresh air demand. In this mode, outdoor air can be controlled to be introduced into the room from the fresh air duct of the first indoor unit corresponding to at least one space with general fresh air demand, and indoor air is prohibited from being discharged from the exhaust duct of the second indoor unit corresponding to at least one space without fresh air introduction demand.

[0070] In some embodiments of the present application, if the first information indicates that the independent space where at least one first indoor unit is located has a demand for introducing fresh air, and the second information indicates that the independent space where at least one second indoor unit is located has no demand for introducing fresh air, at least one first indoor unit and at least one second indoor unit are controlled to operate in the second working mode.

[0071] It can be understood that if the first information indicates that at least one independent space where a first indoor unit is located has a general fresh air demand; the second information indicates that the air quality of at least one independent space where a second indoor unit is located is qualified, that is, the CO2 concentration and the PM2.5 concentration do not exceed the standard, then the air conditioner can be triggered to enter the simple fresh air mode; and then the outdoor air is controlled to be introduced into the room from the fresh air duct of the first indoor unit corresponding to at least one space with general fresh air demand, and the indoor air is prohibited from being discharged from the exhaust duct of the second indoor unit corresponding to at least one space without fresh air introduction demand.

[0072] In the present application, refer to Figure 4As shown, if both room 1 and room 2 have general fresh air demand, and the living room has no fresh air introduction demand, the air conditioner enters the simple fresh air mode, and can introduce fresh air through the indoor units of room 1 and room 2, while prohibiting the discharge of indoor air from the indoor unit of the living room; if you want to introduce more fresh air into the room, you can also turn on the air supply fan of the indoor unit of the living room.

[0078] In some embodiments of the present application, the control unit 603 is also used to control multiple first indoor units and at least one second indoor unit to operate in the first working mode if the first information indicates that the independent space where the multiple first indoor units are located has a demand for introducing fresh air, and the second information indicates that the independent space where at least one second indoor unit is located has no demand for introducing fresh air.

[0079] In some embodiments of the present application, the control unit 603 is also used to control the operation of at least one first indoor unit for a first duration in the first working mode, and to control the operation of at least one second indoor unit for a first duration; the first duration is determined based on the amount of fresh air introduced by the at least one first indoor unit, the amount of air discharged by the at least one second indoor unit, and the spatial volume of the independent space where the multiple indoor units are located.

[0080] In some embodiments of the present application, the control unit 603 is further used to control a first indoor unit and at least one second indoor unit to operate in the first working mode if the first information indicates that the independent space where the first indoor unit is located has a demand for fresh air introduction, and the second information indicates that the independent space where the at least one second indoor unit is located has no demand for fresh air introduction.
