Detailed Description
Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.
In the embodiment, the concentration of the outdoor carbon dioxide is usually 400-500ppm, and based on the indoor air instruction standard, it is found that the comfort of the user can be high by controlling the indoor carbon dioxide concentration to be below 600ppm, so that it is necessary to control the indoor carbon dioxide concentration to be within the set concentration range.
A method for controlling the carbon dioxide collecting device according to the embodiment of the present invention will be described below.
Referring to fig. 1 and 2, a control method of a carbon dioxide collecting device according to an embodiment of the present invention, which is applicable to a carbon dioxide collecting device including a filter for absorbing carbon dioxide, is described, as shown in fig. 1, the control method of a carbon dioxide collecting device according to an embodiment of the present invention includes at least steps S1 to S4.
And step S1, determining that the preset release condition is met, and controlling the filter element to release the absorbed carbon dioxide.
In an embodiment, the preset releasing condition is that carbon dioxide collected by a filter element of the carbon dioxide collecting device is in a saturated state. Specifically, when the carbon dioxide collection device absorbs carbon dioxide, the concentration of the carbon dioxide absorbed by the filter element needs to be detected in real time, when the carbon dioxide is determined to be saturated when the filter element absorbs carbon dioxide, the carbon dioxide collection device is considered to meet a preset release condition, and at the moment, the carbon dioxide collection device is controlled to release the absorbed carbon dioxide so as to discharge the absorbed carbon dioxide outdoors, so that the carbon dioxide collection module can continue to absorb the carbon dioxide.
Step S2, upon release of the absorbed carbon dioxide, obtains a first carbon dioxide concentration in the air before passing through the filter element and a second carbon dioxide concentration in the air after passing through the filter element.
The first carbon dioxide concentration is, for example, Ca, the carbon dioxide concentration in the air before passing through the filter element, the second carbon dioxide concentration is, for example, Cb, and the second carbon dioxide concentration is the carbon dioxide concentration in the air after passing through the filter element.
Specifically, in the process of releasing the absorbed carbon dioxide by the carbon dioxide collecting device, the released carbon dioxide is discharged outdoors through the exhaust channel along with the indoor air, so that the condition that the carbon dioxide is released by the filter element is judged by detecting the concentration of the carbon dioxide in the air flowing through the filter element in the exhaust channel and the concentration of the carbon dioxide flowing through the filter element, namely, detecting the first carbon dioxide concentration Ca and the second carbon dioxide concentration Cb, and the working condition that the carbon dioxide is continuously released or stopped by the filter element is accurately controlled.
Step S3, it is determined whether the second carbon dioxide concentration is less than or equal to a target carbon dioxide concentration, where the target carbon dioxide concentration is a sum of the first carbon dioxide concentration and a preset carbon dioxide concentration.
In an embodiment, the preset carbon dioxide concentration is, for example, denoted as Δ C, and the preset carbon dioxide concentration Δ C is usually a deviation of the carbon dioxide detection device. The target carbon dioxide concentration is the sum of the first carbon dioxide concentration Ca and a preset carbon dioxide concentration Δ C, that is, the target carbon dioxide concentration is Ca + Δ C.
After the first carbon dioxide concentration Ca and the second carbon dioxide concentration Cb are determined, the size relation between the second carbon dioxide concentration Cb and the target carbon dioxide concentration is compared, and the carbon dioxide concentration in the air after flowing through the filter element is judged according to the size relation between the first carbon dioxide concentration Ca and the second carbon dioxide concentration Cb, so that whether the carbon dioxide absorbed by the filter element is released or not is determined, and the working condition of continuously releasing or stopping the carbon dioxide of the filter element is accurately controlled.
And step S4, if the second carbon dioxide concentration is less than or equal to the target carbon dioxide concentration, controlling the filter element to stop releasing the absorbed carbon dioxide.
In the embodiment, if it is determined that the second carbon dioxide concentration Cb is less than or equal to the target carbon dioxide concentration, the carbon dioxide concentration in the exhaust channel after the carbon dioxide is released by the filter element is considered to have a smaller difference with the carbon dioxide concentration in the exhaust channel before the carbon dioxide is released by the filter element, at this time, the carbon dioxide release by the filter element is considered to be completed, and the filter element is controlled to stop releasing the carbon dioxide, so that the carbon dioxide absorption is continued after the carbon dioxide release is completed, and the carbon dioxide collecting device can be recycled; and if the second carbon dioxide concentration Cb is determined to be greater than the target carbon dioxide concentration, the carbon dioxide is not released completely, and at the moment, the filter element is controlled to continuously release the carbon dioxide.
According to the control method of the carbon dioxide collecting device provided by the embodiment of the invention, in the process of releasing carbon dioxide from the filter element, acquiring a first carbon dioxide concentration in air before flowing through the filter element and a second carbon dioxide concentration in air after flowing through the filter element, after the first carbon dioxide concentration and the second carbon dioxide concentration are determined, the second carbon dioxide concentration and the target carbon dioxide concentration are judged, so as to judge the condition of the carbon dioxide released by the filter element according to the second carbon dioxide concentration and the target carbon dioxide concentration, thereby controlling the filter element to stop releasing the absorbed carbon dioxide when the second carbon dioxide concentration is determined to be less than or equal to the target carbon dioxide concentration so as to accurately control the working condition of the carbon dioxide collecting device, therefore, after the release is finished, the adsorption of the carbon dioxide can be continuously carried out, so that the reuse of the filter element is realized.
In some embodiments, controlling the filter element to stop releasing the absorbed carbon dioxide comprises: and controlling the heating device to stop heating the filter element so as to stop releasing the absorbed carbon dioxide. Specifically, the filter element is controlled to stop releasing the absorbed carbon dioxide, meanwhile, the heating device is stopped to continue heating the filter element, and the exhaust fan is controlled to be turned off, so that the filter element stops releasing the absorbed carbon dioxide.
In some embodiments, after controlling the carbon dioxide collection device to stop releasing carbon dioxide, the method further comprises: acquiring a first temperature value of the filter element; judging whether the first temperature value is smaller than a preset safety value or not; if so, controlling the air exhaust fan to be closed, otherwise, controlling the air exhaust fan to be continuously opened until the first temperature is lower than a preset safety value. It can be understood that, predetermine the safe value and be filter core cooling safe value, predetermine the safe value through setting up, when filter core temperature reduces to below the preset safe value, the fan of controlling to exhaust is closed, need not to continue to cool down to the filter core to guarantee that the follow-up normal work that can of filter core.
In the embodiment, after the carbon dioxide is determined to be released by the filter element, the heating module is controlled to stop heating, however, the filter element still has residual heat, at this time, a first temperature value of the filter element is obtained, the magnitude relation between the first temperature value and a preset safety value is judged, when the first temperature value is smaller than the preset safety value, the temperature of the filter element is considered to be reduced to the preset safety value, at this time, the exhaust fan is controlled to be closed, and the filter element does not need to be cooled continuously; when the first temperature value is greater than or equal to the preset safety value, the exhaust fan is controlled to be continuously started to rapidly cool the filter element until the temperature value of the filter element is reduced below the preset safety value.
In some embodiments, the predetermined release condition is determined to be satisfied when the carbon dioxide concentration of the filter element is greater than or equal to an absorption saturation value corresponding to the filter element.
In the embodiment, during the operation of the air conditioner, the concentration value of carbon dioxide in the indoor air is detected, when the concentration value of carbon dioxide in the indoor air reaches a preset concentration threshold value, the content of carbon dioxide in the indoor air is considered to be overproof, and at the moment, the carbon dioxide in the indoor air is absorbed by the carbon dioxide collecting device so as to reduce the concentration of carbon dioxide in the indoor air.
When the filter element absorbs carbon dioxide, the concentration of the carbon dioxide absorbed by the filter element is detected, when the concentration of the absorbed carbon dioxide is greater than or equal to the absorption saturation value of the filter element, the carbon dioxide absorbed by the filter element is considered to reach a saturation state, and at the moment, the carbon dioxide collecting device is considered to meet a preset release condition. Wherein, the absorption saturation value of the filter element can be 600-1300PPM, for example, the absorption saturation value is determined to be 1000 PPM.
In some embodiments, controlling the carbon dioxide collection device to release absorbed carbon dioxide comprises: and controlling the heating device to be started to heat the filter element so as to release carbon dioxide. Specifically, when the carbon dioxide collecting device is controlled to release carbon dioxide, the heating device is controlled to be turned on to heat the filter element, wherein the heating of the filter element includes electric heating, microwave heating, infrared heating, steam heating and the like, and when the filter element is heated by the electric heating, the heating temperature can be controlled to be in a temperature range of 60 ℃ to 150 ℃, for example, the heating temperature can be controlled to be 80 ℃. Wherein, when the temperature of the filter element reaches a preset temperature, such as 80 ℃, the efficiency of the filter element for releasing carbon dioxide is higher.
In some embodiments, before controlling the heating device to be turned on, the method further includes: and controlling the filter element to move to a preset carbon dioxide release area, and controlling the exhaust fan to be started so as to blow air to the filter element. Specifically, when the carbon dioxide saturation is collected to the filter core, through motion module control filter core to remove the filter core to predetermined carbon dioxide release region, after detecting that the filter core module is in the correct position, the control fan of airing exhaust is opened, and the control passageway of airing exhaust is opened, guarantees that indoor air can discharge to outdoor through the passageway of airing exhaust, thereby, carbon dioxide discharges to outdoor through the passageway of airing exhaust.
In some embodiments, after the heating device is controlled to be turned on to heat the filter element, the method further comprises: acquiring a second temperature value of the filter element; judging whether the second temperature value reaches a target temperature threshold value, wherein the target temperature threshold value is the difference value between a preset filter element release temperature threshold value and a preset temperature return difference; if so, controlling the heating device and/or the exhaust fan to maintain the second temperature at the target temperature threshold, otherwise, controlling the heating device to continuously heat the filter element until the second temperature reaches the target temperature threshold.
In an embodiment, the second temperature value is, for example, denoted T, and the predetermined filter element release temperature threshold is, for example, denoted TIs provided withAfter the heating device is started to heat the filter element, a second temperature value T of the filter element is obtained, and the second temperature value T is compared with a preset filter element release temperature threshold value TIs provided withWhen the second temperature value T is less than the preset filter element release temperature threshold value TIs provided withAnd controlling the heating device to continuously heat the filter element, and when the second temperature value T is greater than or equal to the preset filter element release temperature threshold value TIs provided withWhen the temperature of the filter element reaches the target temperature threshold value, the heating device and/or the air exhaust fan are controlled to keep the filter element at the target temperature threshold value, wherein the filter element is controlled to be kept at the target temperature threshold valueThe standard temperature threshold value can be adjusted by properly adjusting the wind speed of the exhaust fan or adjusting the power of the heating device so as to regulate and control the temperature of the filter element. And when the second temperature does not reach the target temperature threshold, for example, the second temperature value is not equal to the target temperature threshold, controlling the heating device to be continuously started to heat the filter element, continuously judging the magnitude relation between the temperature value of the filter element and the target temperature threshold in the heating process, and keeping the temperature of the filter element at the target temperature threshold when the temperature value of the filter element reaches the target temperature threshold.
