The technical scheme provided by the embodiment of the invention is applied to the oxygen-enriched air conditioner to control the opening states and the running time of the fresh air ventilation device and the oxygen generation device of the oxygen-enriched air conditioner so as to accurately control the content of indoor oxygen.
Referring to fig. 1, fig. 1 is a flow chart of a control method of an oxygen-enriched air conditioner according to an embodiment of the invention. As shown in FIG. 1, the method includes the following steps S1-S5.
S1, acquiring indoor oxygen concentration and outdoor air quality in real time.
In a specific implementation, the indoor oxygen concentration and the outdoor air quality are obtained in real time. Specifically, in one embodiment, the oxygen concentration in the room where the oxygen-enriched air conditioner is located is collected by an oxygen measuring device arranged on the indoor unit, and specifically, the oxygen concentration in the room can be measured by an oxygen content probe; the outdoor air quality at the local time is obtained in real time through the Internet, or the outdoor air quality at the local time is obtained after the outdoor air quality is connected with the intelligent wearing product of the user.
According to the related data, the value range of the air pollution index is set to be 0-500, wherein 0-50, 51-100, 101-200, 201-300 and the pollutant concentration limit values of the class I, class II, class III, class IV and class V standard of the daily average value in the national air quality standard are respectively corresponding. The air quality is evaluated to be excellent, and the air quality has no influence on human health; grade II, the air quality is evaluated as good, and no obvious influence is caused to human health; class III, light pollution, and irritation symptoms of healthy people; grade IV, moderate pollution, and general irritation symptoms for healthy people; grade V, severe pollution, severe irritation symptoms appear in healthy people. In this example, therefore, outdoor air quality was defined as good when the outdoor contaminant concentrations were class I, class II, and poor when the outdoor contaminant concentrations were class III, class IV, and class V.
S2, judging whether to start an oxygen supply mode according to the indoor oxygen concentration.
In specific implementation, whether to start an oxygen supply mode is judged according to the indoor oxygen concentration. Specifically, whether to start the oxygen delivery mode may be determined by comparing the indoor oxygen concentration acquired in real time with a preset oxygen concentration. When the indoor oxygen concentration is too low, the working efficiency of indoor personnel may be reduced and head, lung and circulatory system problems may result. According to the related research, the indoor oxygen concentration needs to reach more than a certain threshold value, for example, the oxygen concentration is more than 22%, so that the normal life and working state of indoor personnel can be ensured. In this embodiment, the above threshold is defined as a first preset oxygen concentration, that is, whether to turn on the oxygen delivery mode is determined by determining whether the indoor oxygen concentration exceeds the first preset oxygen concentration. It should be noted that: the user may customize the value of the first preset oxygen concentration as desired.
Specifically, in one embodiment, if the indoor oxygen concentration is lower than or equal to the first preset oxygen concentration, the oxygen delivery mode is turned on. And if the indoor oxygen concentration is higher than the first preset oxygen concentration, closing the oxygen supply mode. Under the first preset oxygen concentration (22%), indoor personnel can normally live and work, so that the oxygen supply mode is closed to save energy. At the moment, the oxygen-enriched air conditioner is controlled to run in a starting mode, so that the user requirement can be met.
And S3, if the oxygen supply mode is determined to be started, determining whether the started oxygen supply mode is a first oxygen supply mode or a second oxygen supply mode according to the outdoor air quality.
In specific implementation, if the open oxygen supply mode is determined, determining whether the open oxygen supply mode is a first oxygen supply mode or a second oxygen supply mode according to the outdoor air quality, wherein the first oxygen supply mode is to open the oxygen generator and open the fresh air ventilator, and the second oxygen supply mode is to open the oxygen generator but not open the fresh air ventilator. The fresh air ventilator is used for delivering outdoor air to the indoor, so that whether the fresh air ventilator is started or not is judged according to the quality of the obtained outdoor air.
Specifically, in one embodiment, if the outdoor air quality is good, the opened oxygen delivery mode is determined to be the first oxygen delivery mode. Under the condition that the outdoor air quality is good, the first oxygen feeding mode is started, namely, the fresh air outside is supplemented into the room through the fresh air ventilator, and meanwhile, the oxygen generator is started to supply oxygen for the room, so that the indoor oxygen concentration is improved, and the resource consumption of oxygen supply by the oxygen generator alone is saved.
And if the outdoor air quality is poor, determining that the opened oxygen supply mode is a second oxygen supply mode. Specifically, in one embodiment, when the outdoor air quality is poor, it is not suitable to supplement the outdoor air into the room, so the oxygen is supplied to the room by the oxygen generating device alone to increase the indoor oxygen concentration.
S4, acquiring the number of indoor personnel and the personnel activity state.
In a specific implementation, the number of people in a room and the activity state of the people are obtained. In an embodiment, the detecting device detects the number of people and the activity state of the people in the room, and specifically, the detecting device may be an infrared detecting device, a millimeter wave radar device, a scanning camera or the like, which can intuitively detect the number of people and the activity state of the people.
S5, controlling the operation time of the oxygen supply mode according to the indoor oxygen concentration, the opened oxygen supply mode, the number of indoor personnel and the personnel activity state.
In specific implementation, the operation time of the oxygen supply mode is controlled according to the indoor oxygen concentration, the opened oxygen supply mode, the indoor personnel number and the personnel activity state. Specifically, in an embodiment, the operation time of the oxygen delivery mode is controlled by a plurality of indexes to achieve the effect of precisely controlling the oxygen content in the room, so as to improve the use experience of the user.
According to the related study, the oxygen concentration below 18% can reduce the working efficiency of indoor personnel and can cause problems of head, lung and circulatory system, so in the embodiment, the second preset oxygen concentration is set to 20%, the third preset oxygen concentration is set to 18%, and the operation time of the first oxygen feeding mode or the second oxygen feeding mode of the oxygen-enriched air conditioner is controlled in the range of three sections of oxygen concentration by combining with the first preset oxygen concentration of 22%.

In a specific implementation, if the indoor oxygen concentration is higher than or equal to the second preset oxygen concentration and lower than or equal to the first preset oxygen concentration, the oxygen supply mode is a first oxygen supply mode, and the first oxygen supply mode is controlled to operate according to a first preset time group according to the number of indoor people and the personnel activity state.
