It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0040] Figure 2 is a flow chart of a fresh air control method for an air conditioner according to an embodiment of the present invention. Figure 2 As shown, the method comprises the following steps:

[0041] Step S202, obtaining a target area in the target room where the air conditioner is located, wherein the target area is an area where a target object moves among a plurality of divided areas, and the plurality of divided areas are areas obtained by dividing the detectable area of ​​the target room.

[0042] In this embodiment, it is possible to first determine which areas in the room where the air conditioner is located are occupied by people, and how many areas are occupied by people in total.

[0043] According to the above embodiment of the present invention, before the above step S202, before obtaining the target area in the target room where the air conditioner is located, the fresh air control method of the air conditioner also includes: obtaining the maximum detection range of the detection component in the air conditioner, wherein the detection component is used to detect the position of the target object in the target room; determining the area detected by the detection component within the maximum detection range as a detectable area; and dividing the detectable area in equal proportion according to the area to obtain a plurality of divided areas.

[0044] Optionally, the above-mentioned detection components may include but are not limited to a millimeter wave radar detection device arranged on the air conditioner, a sensor and a camera that have a communication relationship with the air conditioner, etc.

[0045] Combine the following Figure 3 and Figure 4 The above embodiments of the present invention are described in detail. Figure 3 is a schematic diagram of an air conditioner according to an embodiment of the present invention, Figure 4 is a schematic diagram of a room area division result according to an embodiment of the present invention.

[0046] like Figure 3As shown, the air conditioner provided in the embodiment of the present invention is provided with a millimeter-wave radar detection device on the upper part, the upper middle part is the left and right fan systems of the air conditioner, and the lower part is the fresh air outlet 1 (with fresh air fan 1, i.e., the first fresh air fan) and the fresh air outlet 2 (with fresh air fan 2, i.e., the second fresh air fan) arranged inside; the millimeter-wave radar detection device is mainly used to locate the activity position of people in the room, accurately count the number of people, and identify the status of people. By collecting, analyzing and processing the personnel status data, the air conditioner and fresh air operation status are controlled to meet the constantly changing load requirements and fresh air volume requirements of the room.

[0047] It should be noted that, usually, an air-conditioning system will be equipped with one or more fresh air fans, and the specific number depends on the size of the air-conditioning system, the use environment and the design requirements. In this embodiment, an air conditioner equipped with two fresh air fans is taken as an example for explanation.

[0048] like Figure 4 As shown, it can be Figure 3 The maximum area (detectable area) that can be detected by the millimeter-wave radar detection device shown is divided into multiple divided areas in equal proportion according to the area, and each divided area is labeled; for example, it can be divided into 5 equal parts, and the area corresponding to each part is used as a divided area, and they are labeled 1, 2, 3, 4, and 5 from left to right.

[0049] It should be noted that the fresh air fans mentioned in the embodiments of the present invention include fresh air fans 1 and fresh air fans 2.

[0050] In the above embodiment of the present invention, after obtaining multiple divided areas, the fresh air control method of the air conditioner also includes: performing secondary area division on the detectable area according to the number of fresh air fans to obtain new divided areas with the same number as the fresh air fans, wherein the new divided areas are a combination of divided areas.

[0051] In this embodiment, the area detectable by the millimeter-wave radar detection device is re-divided. In fact, it is classified according to the positions of the five divided areas and the positions of the fresh air fans 1 and 2, so as to control the air conditioner to carry out directional and precise fresh air supply in different areas. Therefore, the new divided areas obtained by the secondary division are actually a combination of the five divided areas obtained above; for example, the 1st, 2nd, and 3rd divided areas can be combined together as the first divided area, and the fresh air fan 1 can supply fresh air to the first divided area; the 4th and 5th divided areas can be combined together as the second divided area, and the fresh air fan 2 can supply fresh air to the second divided area.

[0052] Step S204, when it is determined that the number of regions of the target area is less than the total number of divided regions, the density of people in the target room is obtained, wherein the density of people is determined by the number of people of the target object.

[0053] In this embodiment, after the air conditioner is turned on and running, if the number of areas where the millimeter-wave radar detection device detects that there are people active is less than the total number of divided areas (here, 5), it is necessary to further analyze the density of people in the current room, that is, the number of people in the room, to determine the operation mode of the fresh air fan. The situation in which the millimeter-wave radar detection device detects that there are people active in all divided areas after the air conditioner is turned on and running is described in detail below and will not be repeated here.

[0054] Step S206, determining the operation mode of the fresh air fan in the air conditioner according to the comparison result between the personnel density and the density threshold.

[0055] In this embodiment, the operation mode of the fresh air fan can be determined according to the comparison result between the personnel density and the density threshold obtained in the previous step S204.

[0056] According to the above embodiment of the present invention, in the above step S206, the operation mode of the fresh air fan in the air conditioner is determined according to the comparison result between the population density and the density threshold, including: when the comparison result indicates that the population density is less than the density threshold, the operation mode is determined to be the initial mode; when the comparison result indicates that the population density is not less than the density threshold, the operation mode is determined to be the gathering mode.

[0057] Specifically, when the number of people detected is less than N (density threshold), the fresh air fan operates in the initial mode; when the number of people detected is not less than N, the fresh air fan operates in the gathering mode. The different operating modes here indicate different wind speeds of the fresh air fan, which are divided into three gears: high, medium, and low. The fresh air fan operates at the medium wind speed in the initial mode and at the high wind speed in the gathering mode.

[0058] Step S208, controlling the fresh air fan to operate according to the operation mode so that the energy consumption of the air conditioner reaches the minimum energy consumption, wherein the minimum energy consumption is the minimum energy that the air conditioner needs to consume under the condition that the fresh air delivered by the fresh air fan meets the required fresh air volume.

[0059] In this embodiment, the fresh air fan can be controlled to operate according to the operation mode obtained by the analysis in the above steps, so that the fresh air fan can accurately deliver fresh air in a directional and quantitative manner to reduce energy loss.

[0060] According to the above embodiment of the present invention, in the above step S208, when the number of fresh air fans is two, the fresh air fans include: a first fresh air fan and a second fresh air fan, and the new divided areas include: a first divided area and a second divided area, and the fresh air fans are controlled to operate according to the operation mode, including: when the number of areas is zero, the first fresh air fan and the second fresh air fan are controlled to be turned off; when the number of areas is greater than zero and not greater than the number threshold, the position information of the target object is detected by the detection component, wherein the number threshold is less than the total number; when it is determined based on the position information that the divided areas included in the target area are all the first divided areas, the first fresh air fan is controlled to operate according to the corresponding operation mode; when it is determined based on the position information that the divided areas included in the target area are all the second divided areas, the second fresh air fan is ... The fresh air fan operates in a corresponding operation mode; when the divided areas included in the target area determined based on the location information include both the first divided area and the second divided area, the first fresh air fan is controlled to operate in an operation mode corresponding to a first comparison result between the first personnel density and the density threshold in the first divided area, and the second fresh air fan is controlled to operate in an operation mode corresponding to a second comparison result between the second personnel density and the density threshold in the second divided area, wherein the first personnel density is determined according to the number of target objects in the current first divided area, and the second personnel density is determined according to the number of target objects in the current second divided area; when the number of areas is greater than the number threshold but not greater than the total number, the first fresh air fan and the second fresh air fan are both controlled to operate in a gathering mode.

[0061] Combine the following Figure 5 The above embodiments of the present invention are described in detail. Figure 5 FIG. 1 is a flow chart of a fresh air control method for an air conditioner according to an embodiment of the present invention. Figure 5 As shown, after the air conditioner is turned on and running, the fresh air fan can be controlled to operate in a corresponding operating mode according to the status of people in the room collected by the millimeter radar detection wave (including people density and target area, that is, the divided area where people are active), and the changes in the status of people can be continuously monitored during the operation of the air conditioner to adjust the operating mode of the fresh air fan in real time to improve the comfort of the user experience.

[0062] Specifically, after the air conditioner is turned on and running, if it is detected that there is no human activity in the five divided areas, the fresh air fans 1 and 2 are controlled to be turned off, and the fresh air outlets 1 and 2 are also closed accordingly to reduce energy loss.

[0063] If human activities are detected in 3 (quantity threshold) or less divided areas, it is necessary to determine whether the divided area with human activities belongs to the first divided area or the second divided area; when the divided areas with human activities all belong to the first divided area, the operation mode of the fresh air fan 1 can be determined based on the comparison result of the overall population density in the room and the density threshold. For example, when human activities are detected in any of the 1st, 2nd, and 3rd divided areas and the population density is less than the density threshold, the fresh air fan 1 is controlled to operate according to the initial mode, that is, the damper of the fresh air outlet 1 is opened, the gear of the fresh air fan 1 is operated at the middle wind gear, and the left fan of the air conditioner is controlled to operate at the wind gear set by the user; similarly, when human activities are detected in any of the 4th and 5th divided areas, the operation mode of the fresh air fan 2 can be determined based on the comparison result of the overall population density in the room and the density threshold. When the density of people is not less than the density threshold, the fresh air fan 2 is controlled to operate in the gathering mode, that is, the damper of the fresh air outlet 2 is opened, the gear of the fresh air fan 2 is operated at the high wind gear, and the speed of the right fan of the air conditioner is controlled to be increased by n revolutions compared with the speed of the fresh air fan when it is running in the initial mode, so as to increase the air volume of the air conditioning circulation and accelerate the indoor fresh air circulation; when there are both areas belonging to the first divided area and areas belonging to the second divided area in the divided area where people are active, it is necessary to control the fresh air fan 1 to operate in the operating mode corresponding to the comparison result of the first personnel density in the first divided area with the density threshold, and control the fresh air fan 2 to operate in the operating mode corresponding to the comparison result of the second personnel density in the second divided area with the density threshold. For example, when there are more than N people active in the first and second divided areas, and no more than N people active in the fifth divided area, it is necessary to control the fresh air fan 1 to operate in the gathering mode, and control the fresh air fan 2 to operate in the initial mode.

[0064] If it is detected that there are people active in any of the four divided areas, the fresh air fans 1 and 2 are controlled to operate in the operating mode corresponding to the comparison result between the overall personnel density in the room and the density threshold. For example, when it is detected that there are no more than N people active in any of the four divided areas, the fresh air fans 1 and 2 are controlled to operate in the initial mode; when it is detected that there are more than N people active in any of the four divided areas, the fresh air fans 1 and 2 are controlled to operate in the party mode.

[0065] If human activities are detected in all five divided areas, there is no need to judge the density of people in the room, and both fresh air fans 1 and 2 can be directly controlled to operate in party mode.

[0067] Specifically, during the operation of the air conditioner, the millimeter-wave radar detection device will continuously detect changes in the status of people in the room to adjust the operation mode of the fresh air fan in real time; for example, when the fresh air fan is running in the initial mode, if it is detected that the current population density is not less than the density threshold, the fresh air fan is controlled to switch to the gathering mode; when the fresh air fan is running in the gathering mode, if it is detected that the current population density is less than the density threshold, the fresh air fan is controlled to switch to the initial mode.

[0069] Specifically, when the fresh air fan 1 switches from the initial mode to the party mode, the left fan speed of the air conditioner can be controlled to increase by n revolutions (predetermined value), and when the fresh air fan 2 switches from the initial mode to the party mode, the right fan speed of the air conditioner can be controlled to increase by n revolutions, so as to increase the circulating air volume of the air conditioner and accelerate the indoor fresh air circulation; in addition, when the fresh air fans 1 and 2 are operating according to the initial mode, the left fan and the right fan operate according to the wind speed set by the user.

[0070] According to the above embodiment of the present invention, the fresh air control method of the air conditioner also includes: when the first fresh air fan and the second fresh air fan are both operating in the gathering mode, controlling the compressor of the air conditioner to operate according to the frequency upper limit value.

[0071] Specifically, when the fresh air fans 1 and 2 are operating in the gathering mode at the same time, that is, when the fresh air fans 1 and 2 are operating at the high wind gear at the same time, the frequency boost value upper limit frequency (frequency upper limit value) of the compressor is controlled to operate so as to increase the system heat exchange to meet the high load demand of the room.

[0073] Therefore, the technical solution provided by the above-mentioned embodiment of the present invention solves the technical problem in the related art that the traditional air conditioner with a fresh air system cannot accurately and quantitatively introduce fresh air according to the changes in the number of people in the room, which easily causes energy loss.
