The technical scheme provided by the embodiment of the invention is applied to the oxygen-enriched air conditioner to control the opening state 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 schematic flow chart of a control method of an oxygen-enriched air conditioner according to an embodiment of the present invention. As shown in FIG. 1, the method includes the following steps S1-S5.
And S1, acquiring the indoor oxygen concentration and the outdoor air quality in real time.
In specific implementation, the indoor oxygen concentration and the outdoor air quality are obtained in real time. Specifically, in one embodiment, the indoor oxygen concentration of the oxygen-enriched air conditioner is acquired through an oxygen measuring device arranged on an indoor unit, and specifically, the indoor oxygen concentration can be measured through an oxygen content probe; the outdoor air quality of the local current time is obtained in real time through the Internet, or the outdoor air quality of the local current time is obtained after the outdoor air quality is connected with the intelligent wearable product of the user.
According to the relevant data, the value range of the air pollution index is 0-500, wherein 0-50, 51-100, 101-200, 201-300 and more than 300 correspond to the pollutant concentration limit values of the I-level standard, the II-level standard, the III-level standard, the IV-level standard and the V-level standard of the daily mean value in the national air quality standard respectively. Grade I, the air quality evaluation is excellent, and the air quality evaluation has no influence on human health; II, evaluating the air quality to be good, and having no obvious influence on the human health; grade III, mild pollution, and irritative symptoms of healthy people; grade IV, moderate pollution, and common irritation symptoms of healthy people; grade V, severe pollution, and severe irritation symptoms in healthy people. Therefore, in this embodiment, the outdoor air quality is defined as good when the outdoor pollutant concentration is class I or class II, and poor when the outdoor pollutant concentration is class III, class IV or class V.
And S2, judging whether to start the oxygen supply mode according to the indoor oxygen concentration.
In specific implementation, whether the oxygen supply mode is started or not is judged according to the indoor oxygen concentration. Specifically, whether to start the oxygen supply mode may be determined by comparing the indoor oxygen concentration acquired in real time with a preset oxygen concentration. When the oxygen concentration in the room is too low, the efficiency of the room personnel is reduced and head, lung and circulatory problems may result. According to related researches, the normal life and working state of indoor personnel can be guaranteed only when the indoor oxygen concentration reaches a certain threshold value or more, for example, the oxygen concentration is 22% or more. In this embodiment, the threshold is defined as a first predetermined oxygen concentration, that is, whether to start the oxygen supply mode is determined by determining whether the indoor oxygen concentration exceeds the first predetermined oxygen concentration. It should be noted that: the user can customize the value of the first preset oxygen concentration according to the requirement.
Specifically, in one embodiment, the oxygen feed mode is activated if the indoor oxygen concentration is less than or equal to a first predetermined oxygen concentration. And if the indoor oxygen concentration is higher than a first preset oxygen concentration, closing the oxygen supply mode. Under the first preset oxygen concentration (22%), indoor personnel can work normally, so the oxygen supply mode is closed to save energy. At the moment, the oxygen-enriched air conditioner is controlled to operate in a mode when the air conditioner is started, and the requirements of users can be met.
And S3, if the oxygen supply mode is determined to be started, determining whether the started oxygen supply mode is the first oxygen supply mode or the second oxygen supply mode according to the outdoor air quality.
In specific implementation, if the oxygen supply mode is determined to be started, whether the started oxygen supply mode is a first oxygen supply mode or a second oxygen supply mode is determined according to the outdoor air quality, wherein the first oxygen supply mode is to start the oxygen generation device and start the fresh air ventilation device, and the second oxygen supply mode is to start the oxygen generation device but not start the fresh air ventilation device. The fresh air ventilation device is used for conveying outdoor air to the indoor space, so that whether the fresh air ventilation device 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 oxygen delivery mode that is turned on is determined to be the first oxygen delivery mode. By opening the first oxygen supply mode under the condition that the outdoor air quality is good, namely, the fresh air outside is supplemented into the room through the fresh air ventilation device, and the oxygen generation device is simultaneously opened to supply oxygen to the room, so that the concentration of the oxygen in the room is improved, and the resource consumption of oxygen supply by the oxygen generation device is saved.
And if the outdoor air quality is poor, determining that the started oxygen delivery mode is a second oxygen delivery 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 generator is used to supply oxygen to the room to increase the indoor oxygen concentration.
And S4, acquiring the number of indoor personnel and the activity state of the personnel.
In specific implementation, the number of indoor personnel and the activity state of the personnel are obtained. In an embodiment, the number of people in the room and the activity state of the people are detected by a detection device, and specifically, the detection device may be an infrared detection device, a millimeter wave radar device, a scanning camera, or the like, which can visually 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 started oxygen supply mode, the indoor personnel number and the personnel activity state.
In a specific implementation, the operation time of the oxygen supply mode is controlled according to the indoor oxygen concentration, the started oxygen supply mode, the indoor personnel number and the personnel activity state. Specifically, in one embodiment, the operation time of the oxygen supply mode is controlled by a plurality of indexes to achieve the effect of accurately controlling the oxygen content in the room, so as to improve the use experience of the user.
According to related researches, the oxygen concentration below 18% reduces the working efficiency of indoor personnel and can cause problems on the head, the lung and the circulatory system, so in the embodiment, the second preset oxygen concentration is set to be 20%, the third preset oxygen concentration is set to be 18%, and the operation time of the first oxygen supply mode or the second oxygen supply mode of the oxygen-enriched air conditioner is controlled in the range of three-stage oxygen concentration by combining the first preset oxygen concentration of 22%.
