An apparatus and method for removing carbon dioxide from a room, an air conditioner, and a storage medium according to embodiments of the present invention will be described with reference to fig. 1 to 3.
Fig. 1 is a schematic structural view of an apparatus for removing carbon dioxide from a chamber according to an embodiment of the present invention, the apparatus including: a filter element 20, a control module 30 and a heating module 40; wherein the content of the first and second substances,
the filter element 20 is used for collecting indoor carbon dioxide;
a heating module 40 disposed adjacent to the filter element 20 for heating the filter element 20 after opening to allow the filter element 20 to release the collected carbon dioxide; it is understood that the heating method of the heating module 40 includes electric heating, microwave heating, infrared heating, steam heating, etc., and preferably, the electric heating is selected to have a heating temperature range of 60-150 ℃.
The control module 30 is configured to control the heating module 40 to be turned on to heat the filter element 20 when it is determined that the carbon dioxide release condition is satisfied, where the carbon dioxide release condition includes: the length of time that the filter element 20 collects carbon dioxide exceeds a first predetermined time threshold, or the absolute value of the first concentration difference of carbon dioxide in the air before and after passing through the filter element 20 is less than or equal to the first predetermined concentration difference.
Specifically, the apparatus 10 for removing carbon dioxide from a room absorbs carbon dioxide from the room through the filter 20 when the concentration of carbon dioxide in the room exceeds a standard. When the control module 30 determines that the time period for which the filter element 20 collects carbon dioxide exceeds a first preset time threshold, or the absolute value of the first concentration difference of carbon dioxide in the air before and after flowing through the filter element 20 is less than or equal to the first preset concentration difference, the filter element 20 is considered to be saturated with carbon dioxide; at this time, the heating module 40 is controlled to be turned on to heat the filter element 20, so that the filter element 20 releases the collected carbon dioxide, and the carbon dioxide in the chamber can be continuously absorbed after the filter element 20 finishes releasing the collected carbon dioxide. Therefore, the device 10 for removing indoor carbon dioxide realizes that the indoor carbon dioxide is at a proper concentration, improves the comfort of a user, and simultaneously, the filter element 20 is repeatedly used, thereby avoiding waste and saving cost. The first preset time threshold value can be determined according to the adsorption capacity and the adsorption efficiency of the carbon dioxide adsorption material in the filter element 20, and the first preset concentration difference value can be determined according to the detection error.
In the embodiment, when the carbon dioxide concentration detection module detects that the indoor carbon dioxide concentration exceeds 600 PPM and 1300PPM, preferably 1000PPM, and the indoor carbon dioxide concentration is considered to be excessive, the device 10 for removing indoor carbon dioxide is turned on to collect the excessive indoor carbon dioxide.
In one embodiment of the present invention, the control module 30 is further configured to: controlling the heating module 40 to be turned off to stop the release of the carbon dioxide from the filter element 20 when it is determined that a release stop condition is satisfied during the release of the collected carbon dioxide from the filter element 20, wherein the release stop condition includes: the length of time that the filter element 20 releases carbon dioxide exceeds a second predetermined time threshold, or the absolute value of the difference between the second concentration of carbon dioxide in the air before and after passing through the filter element 20 is less than or equal to the second predetermined concentration difference.
Specifically, when the filter element 20 releases carbon dioxide, the control module 30 determines that the time period for releasing carbon dioxide by the filter element 20 exceeds a second preset time threshold, or the absolute value of the difference between the second concentrations of carbon dioxide in the air before and after flowing through the filter element 20 is less than or equal to the second preset concentration difference, and considers that the filter element 20 completes the action of releasing carbon dioxide; at this time, the heating module 40 is controlled to be turned off to lower the temperature of the filter element 20, so that the filter element 20 stops releasing carbon dioxide.

the air path switching mechanism 60 is disposed behind the filter element 20, and is configured to switch the air path to the indoor air outlet 70 or the outdoor air outlet 80, so that the air flowing through the filter element 20 flows into the room through the indoor air outlet 70 and circulates or is discharged out of the room through the outdoor air outlet 80.
Specifically, when the filter element 20 collects or releases carbon dioxide, a first preset time threshold for the filter element 20 to absorb carbon dioxide and a second preset time threshold for the filter element 20 to release carbon dioxide are related to the wind speed, and the larger the wind speed is, the smaller the first preset time threshold and the second preset time threshold are. Therefore, the first preset time threshold and the second preset time threshold may be determined according to the wind speeds of different gears of the fan 50.
In an embodiment of the present invention, the air path switching mechanism 60 includes a baffle 90 and a driving unit, one end of the baffle 90 is connected to the rotating shaft, and the driving unit is configured to drive the baffle 90 to rotate around the rotating shaft;

Fig. 2 is a schematic structural view of an apparatus for removing carbon dioxide from a chamber according to another embodiment of the present invention. As shown in fig. 2, in a specific embodiment, the driving unit may be a motor, and when the filter element 20 collects carbon dioxide, the control module 30 controls the motor to drive the baffle 90 to rotate to an opposite vertical position or 90 ° so that the baffle 90 closes the outdoor air outlet and switches to the indoor air outlet, so that air flowing through the filter element 20 flows into the indoor through the indoor air outlet to circulate, so as to collect indoor carbon dioxide; when the filter element 20 releases carbon dioxide, the control module 30 controls the motor to drive the baffle 90 to rotate to a relative horizontal position or 0 degree, so that the baffle 90 seals the indoor air outlet and switches to the outdoor air outlet, and air flowing through the filter element 20 is discharged outdoors through the outdoor air outlet to release carbon dioxide collected by the filter element 20.
In an embodiment of the present invention, after the control module 30 controls the heating module 40 to be turned on, the control module is further configured to: acquiring a first temperature value of the filter element 20; judging whether the first temperature value reaches a target temperature threshold value, wherein the target temperature threshold value is the difference value between a preset release temperature threshold value of the filter element 20 and a preset temperature return difference value; if so, controlling the operating state of the heating module 40 and/or the fan 50 to maintain the first temperature at the target temperature threshold, otherwise, controlling the heating module 40 to continuously heat the filter element 20 until the first temperature reaches the target temperature threshold.
In a specific embodiment, after the control module 30 controls the heating module 40 to be turned on, the filter element 20 is heated by the heating module 40, and after the temperature of the filter element 20 reaches a certain temperature (for example, 80 ℃), the filter element 20 starts to efficiently release the collected carbon dioxide, at this time, the exhaust air speed of the fan 50 and the heating power of the heating module 40 are appropriately adjusted to maintain the temperature of the filter element 20 at 80 ℃, so that the carbon dioxide indoor air is exhausted from the outdoor air outlet under the action of the fan 50.
In one embodiment of the present invention, after the control module 30 controls the heating module 40 to turn off, it is further configured to: acquiring a second temperature value of the filter element 20; judging whether the second temperature value is smaller than a preset safety value or not; if so, the fan 50 is controlled to be closed, otherwise, the fan 50 is controlled to be continuously opened until the second temperature is lower than the preset safety value.
Specifically, when the carbon dioxide is completely released from the filter element 20, the heating module 40 is controlled to be turned off, and at this time, the filter element 20 still has some residual heat, which is likely to cause damage to the filter element 20 and reduce the service life of the filter element 20, so that after the heating module 40 is turned off, the temperature of the filter element 20 needs to be detected, and the temperature of the filter element 20 is reduced to a preset safety value or below by controlling the fan 50, so as to ensure the safety and the service life of the filter element 20. The method specifically comprises the following steps: acquiring the temperature of the filter element 20 by using a temperature sensor, then judging whether the temperature of the filter element 20 is smaller than a preset safety value by using the control module 30, if not, continuously detecting the temperature of the filter element 20, and controlling the fan 50 to continuously blow air so as to cool the filter element 20; if yes, the temperature of the filter element 20 is reduced to a safe value, and the fan 50 is controlled to be turned off, so that the filter element 20 can continue to absorb the indoor carbon dioxide after releasing the collected carbon dioxide.
In one embodiment of the present invention, the filter of the filter cartridge 20 has a honeycomb shape, and the filter is filled with a carbon dioxide adsorbing material, and both sides of the filter are covered with a porous membrane so that air can pass through the porous membrane.
