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 running state of the air conditioner, the indoor is in a closed state to ensure the cooling and heating effects. The concentration of carbon dioxide in the closed space is usually between 500PPM and 700PPM under the condition that no person exists; if a person moves in the closed space, the concentration of the carbon dioxide can be gradually increased along with the respiration of the person. The living conditions of people have a certain range of requirements on the concentration of carbon dioxide in air, and once the concentration of carbon dioxide exceeds the range, people can feel that the air is turbid, breathe smoothly, even feel headache and sleepy, cannot concentrate attention and harm the health of human bodies. In an outdoor open space, the concentration of carbon dioxide is 400-500 PPM, so that the mental state of people is good and the breath is smooth. However, the fresh air conditioner available on the market can increase the oxygen content in the indoor air, but still cannot reduce the carbon dioxide content.

In order to solve the above problems, embodiments of the first aspect of the present invention provide a method for adjusting indoor carbon dioxide concentration, which can effectively reduce indoor carbon dioxide concentration and enable indoor air quality to reach a user comfort index.

A method for adjusting a carbon dioxide concentration in a chamber according to an embodiment of the present invention, which is an apparatus for adjusting a carbon dioxide concentration in a chamber including a carbon dioxide collecting module and a vacuum pump, is described with reference to the accompanying drawings, and as shown in fig. 1, the method includes at least steps S1 to S4.

Step S1, the indoor carbon dioxide concentration is collected.

In an embodiment, the indoor carbon dioxide concentration in the indoor air may be collected by providing a carbon dioxide concentration collector.

And step S2, determining that the concentration of the indoor carbon dioxide reaches a preset concentration threshold, and controlling the carbon dioxide collection module to collect the carbon dioxide in the indoor air.

The preset concentration threshold value can be understood as the maximum concentration of carbon dioxide which is preset and meets the comfortable requirement of a user under the condition that the indoor space is certain. The preset concentration threshold may be set according to actual conditions, such as the size of the indoor space or the number of users, and is not limited thereto. For example, the preset concentration threshold value can be set to 600PPM, since it is beneficial to the health of the user when the indoor carbon dioxide concentration is controlled below 600 PPM.

In the embodiment, since the carbon dioxide concentration exceeds a certain range under the condition that the indoor space is constant, the human health is endangered, therefore, the embodiment of the invention detects the indoor carbon dioxide concentration in real time and compares the indoor carbon dioxide concentration with the preset concentration threshold value, so as to judge whether the content of the carbon dioxide in the indoor air exceeds the range of comfortable demands of users, collect the carbon dioxide in the indoor air when the concentration of the indoor carbon dioxide meets certain conditions, namely reaches a preset concentration threshold, so that, by the following steps S3 and S4, the collected carbon dioxide is discharged to the outside of the room, therefore, the concentration of indoor carbon dioxide is effectively reduced, the indoor air quality reaches the comfortable index of a user, the concentration of indoor carbon dioxide is maintained in the range beneficial to the health of the user, and the problem that the content of carbon dioxide still rises due to the closed indoor space is solved.

Specifically, the method provided by the embodiment of the invention detects the concentration of indoor carbon dioxide in real time, and if the concentration of indoor carbon dioxide is determined to reach the preset concentration threshold, the content of carbon dioxide in indoor air exceeds the standard, which is not beneficial to the health of a user, so that carbon dioxide in indoor air needs to be collected to release the carbon dioxide exceeding the standard in indoor air to the outdoor, and the concentration of indoor carbon dioxide is reduced; if the concentration of the indoor carbon dioxide is determined not to reach the preset concentration threshold, the content of the carbon dioxide in the indoor air does not exceed the standard, the concentration of the indoor carbon dioxide meets the comfortable requirement range of a user, and under the condition, the carbon dioxide in the indoor air does not need to be collected. Therefore, the purpose of reducing the indoor carbon dioxide content is achieved, and the concentration of the indoor carbon dioxide is ensured to be maintained in a range beneficial to the health of users.

In step S3, status information of the collected carbon dioxide is acquired.

The state information may be information that may indicate the carbon dioxide collection degree during the carbon dioxide collection process of the carbon dioxide collection module, such as the weight or concentration of the collected carbon dioxide, or the pressure in the carbon dioxide module or the wind speed collected by the carbon dioxide module during the collection process.

In the embodiment, the state information of the carbon dioxide collection module in the process of collecting the carbon dioxide is obtained in real time, so that the degree of collection of the carbon dioxide by the carbon dioxide collection module is judged according to the change condition of the state information.

And step S4, determining that the collected carbon dioxide reaches a saturation state according to the state information, and controlling a vacuum pump to be started so as to discharge the carbon dioxide collected by the carbon dioxide collection module to the outside.

The requirement of the saturation state may be set according to the maximum collection content of the carbon dioxide by the carbon dioxide collection module, or in combination with the exceeding standard condition of the carbon dioxide content in the indoor air, which is not limited to this.

In the embodiment, in order to ensure that the concentration of the indoor carbon dioxide is maintained in the range beneficial to the health of the user, the embodiment of the invention judges the degree of collecting the indoor carbon dioxide through the change condition of the state information by detecting the state information in the process of collecting the carbon dioxide in real time, so that the content of the residual carbon dioxide in the indoor air can be effectively maintained in the range of the health index of the user on the indoor air quality after the carbon dioxide collected by the carbon dioxide collecting module reaches the saturation state under the condition of meeting the maximum collecting content of the carbon dioxide by the carbon dioxide collecting module.

Specifically, the method of the embodiment of the invention judges the state information in real time, if the state information is determined to meet the set state requirement, the collected carbon dioxide is in a saturated state, the content of the carbon dioxide remaining after the carbon dioxide in the indoor air is collected for the time meets the user comfort index, and then the vacuum pump is controlled to be started to extract the carbon dioxide collected by the carbon dioxide collecting module and convey the collected carbon dioxide to the outdoor, so that the purpose of discharging the carbon dioxide exceeding the standard in the indoor air to the outdoor to reduce the content of the indoor carbon dioxide is realized, and the next collecting operation of the indoor carbon dioxide is facilitated; if the condition information is determined not to meet the set condition requirement, the collected carbon dioxide is in an unsaturated condition, and the carbon dioxide content in the indoor air is still in an overproof condition. Therefore, the purpose of reducing the indoor carbon dioxide content is achieved, and the concentration of the indoor carbon dioxide is ensured to be maintained in a range beneficial to the health of users.

According to the method for adjusting the concentration of the indoor carbon dioxide, when the concentration of the indoor carbon dioxide reaches the preset concentration threshold, the fact that the content of the carbon dioxide in the indoor air exceeds the standard is indicated, and the method is not beneficial to the health of a user, under the condition, the carbon dioxide in the indoor air is collected by controlling the carbon dioxide collecting module, and when the collected carbon dioxide is determined to reach the saturation state, the vacuum pump is controlled to be started, so that the carbon dioxide collected in the carbon dioxide collecting module is discharged to the outside, the purpose of reducing the concentration of the indoor carbon dioxide is achieved, the problem that the content of the carbon dioxide still rises due to the fact that the indoor space is closed is solved, and the quality of the indoor.

In some embodiments, in the method of the embodiments of the present invention, during the releasing of the collected carbon dioxide by the carbon dioxide collecting module, the releasing degree of the carbon dioxide collecting module can be determined by the pressure change of the carbon dioxide in the carbon dioxide collecting module.

Specifically, a pressure value of carbon dioxide in the carbon dioxide collection module is obtained, if a pressure sensor is arranged to detect the pressure value of the carbon dioxide in the carbon dioxide collection module, if the pressure value is determined to be less than or equal to a first preset pressure threshold value, the collected carbon dioxide is completely released, the vacuum pump does not need to work continuously, and therefore the vacuum pump is controlled to be closed; if the pressure value is determined to be larger than the first preset pressure threshold value, the collected carbon dioxide is not completely released, and the vacuum pump needs to work continuously to completely release the carbon dioxide collected in the carbon dioxide collecting module so as to be used for collecting indoor carbon dioxide next time.

The first preset pressure threshold value can be understood as an initial pressure value of the vacuum pump preset when the carbon dioxide collection module does not collect carbon dioxide. The first preset pressure threshold may be set according to actual conditions, and is not limited in this respect.

In some embodiments, the method of the present invention includes controlling the carbon dioxide collection module to move to the carbon dioxide release position before controlling the vacuum pump to be turned on.

Wherein a carbon dioxide release location is understood to be a location where carbon dioxide is emitted by a device that is relatively closed and facilitates adjustment of the carbon dioxide concentration within the chamber. It can be understood that the vacuum pump is disposed at the carbon dioxide releasing position, one end of the vacuum pump is connected to the carbon dioxide releasing position, and the other end of the vacuum pump is connected to the outdoor air, so that the carbon dioxide collected in the carbon dioxide collecting module can be transferred to the outdoor air by the suction of the vacuum pump. That is, when the indoor carbon dioxide concentration release condition is satisfied, the purpose of releasing the collected carbon dioxide to the outdoor space is realized by moving the carbon dioxide collection module to the carbon dioxide release position and controlling the vacuum pump to start.

In some embodiments, the carbon dioxide collecting module is adapted to collect carbon dioxide in the indoor air only when the indoor carbon dioxide concentration exceeds the predetermined concentration threshold, and the carbon dioxide collecting module is adapted to be placed in the enclosed space to avoid contact with the air when the indoor carbon dioxide concentration does not exceed the predetermined concentration threshold. Therefore, when the carbon dioxide collecting module is controlled to collect the carbon dioxide in the indoor air, the carbon dioxide collecting module is controlled to move from the closed space to the carbon dioxide collecting position, that is, to a position in contact with the indoor air, so as to collect the carbon dioxide in the indoor air.

In some embodiments, the status information includes the weight of the collected carbon dioxide, for example, the weight of the collected carbon dioxide can be detected by a weight sensor, that is, the degree of carbon dioxide collection is judged by the change of the weight during the collection process, the content of the carbon dioxide collected by the carbon dioxide collection module increases with the increase of the detected weight value, and when the weight of the collected carbon dioxide is determined to reach a preset weight threshold value, the collected carbon dioxide is in a saturated state. Wherein, the preset weight threshold value is a preset weight value after the carbon dioxide collection module is saturated in adsorption.

Or, the status information includes the concentration of the carbon dioxide, for example, the concentration of the collected carbon dioxide can be detected by a concentration sensor, that is, the collection degree of the carbon dioxide is judged by the change of the concentration in the collection process, the content of the carbon dioxide collected by the carbon dioxide collection module increases with the increase of the detected concentration value, and when it is determined that the concentration of the carbon dioxide in the carbon dioxide collection module reaches a preset concentration threshold, it indicates that the collected carbon dioxide reaches a saturation state. The preset concentration threshold is a concentration value after the preset carbon dioxide collection module is saturated in adsorption.

Or, the state information includes a pressure value, for example, the pressure value of the carbon dioxide in the carbon dioxide collection module can be detected by the pressure sensor, that is, the collection degree of the carbon dioxide is judged by the change of the pressure in the collection process, along with the increase of the detected pressure value, the content of the carbon dioxide collected by the carbon dioxide collection module is increased, and when it is determined that the pressure value of the carbon dioxide in the carbon dioxide collection module reaches a second preset pressure threshold, it is indicated that the collected carbon dioxide reaches a saturated state. The second preset pressure threshold is a preset pressure value after the carbon dioxide collection module is saturated in adsorption.

Or, the state information includes a wind speed value, for example, the wind speed value of the carbon dioxide collected by the carbon dioxide collection module can be detected by the speed sensor, that is, the collection degree of the carbon dioxide is judged by the change of the wind speed in the collection process, along with the decrease of the detected wind speed value, that is, the increase of the wind resistance of the carbon dioxide collected by the carbon dioxide collection module, the content of the carbon dioxide collected by the carbon dioxide collection module is increasing, and when it is determined that the wind speed value of the carbon dioxide collected by the carbon dioxide collection module is smaller than the preset wind speed threshold, it is indicated that the collected carbon dioxide reaches a saturation state. The preset wind speed threshold value is a preset wind speed value after the carbon dioxide collection module is saturated in adsorption.

According to a second aspect of the present invention, an apparatus for adjusting the concentration of carbon dioxide in a room is provided, as shown in fig. 2, the apparatus 10 for adjusting the concentration of carbon dioxide in a room includes a collection module 1, a carbon dioxide collection module 2, a status detection module 3, a vacuum pump 4, and a control module 5.

The acquisition module 1 is used for acquiring the concentration of indoor carbon dioxide; the carbon dioxide collecting module 2 is used for collecting carbon dioxide in indoor air when the concentration of the indoor carbon dioxide reaches a preset concentration threshold; the state detection module 3 is used for acquiring the state information of the collected carbon dioxide; the vacuum pump 4 is used for discharging the carbon dioxide collected by the carbon dioxide collecting module 2 to the outside; the control module 5 is connected with the acquisition module 1, the carbon dioxide acquisition module 2, the state detection module 3 and the vacuum pump 4, and is used for controlling the vacuum pump 4 to be started when the carbon dioxide acquired is determined to reach a saturation state according to the state information.

It should be noted that a specific implementation manner of the apparatus 10 for adjusting indoor carbon dioxide concentration according to the embodiment of the present invention is similar to a specific implementation manner of the method for adjusting indoor carbon dioxide concentration according to any of the above embodiments of the present invention, and please refer to the description of the method for the specific implementation manner, and details are not repeated here for reducing redundancy.

According to the device 10 for adjusting the concentration of the indoor carbon dioxide, when the carbon dioxide collection module 2 determines that the concentration of the indoor carbon dioxide reaches the preset concentration threshold, it is indicated that the content of the carbon dioxide in the indoor air exceeds the standard, and the health of a user is not facilitated, in this case, the carbon dioxide in the indoor air is collected, and when the control module 5 determines that the collected carbon dioxide reaches the saturation state, the vacuum pump 4 is controlled to be started, so that the carbon dioxide collected in the carbon dioxide collection module 2 is discharged to the outside, and therefore the purpose of reducing the concentration of the indoor carbon dioxide is achieved, the problem that the content of the carbon dioxide still rises due to the fact that the indoor space is closed is solved, and the quality of the indoor air reaches the comfortable index of the user.

In some embodiments, as shown in FIG. 2, the apparatus 10 for regulating the concentration of carbon dioxide within a chamber further comprises a pressure sensing module 6.

Specifically, the pressure detection module 6 is used for detecting the pressure value of the carbon dioxide in the carbon dioxide collection module 2. And the control module 5 is connected with the pressure detection module 6 and is further used for controlling the vacuum pump 4 to be closed when the pressure value is determined to be smaller than or equal to the first preset pressure threshold value.

In some embodiments, as shown in fig. 2, the carbon dioxide collection module 2 includes a filter element unit 7 and a drive unit 8.

Wherein the filter element unit 7 is used for absorbing carbon dioxide; the driving unit 8 is connected to the filter element unit 7 for driving the filter element unit 7 to move to the carbon dioxide absorbing position when carbon dioxide is collected in the chamber and driving the filter element unit 7 to move to the carbon dioxide releasing position when carbon dioxide is released. And a vacuum pump 4 is provided at the carbon dioxide releasing position.

It can be understood that under the condition that the indoor carbon dioxide concentration exceeds the standard, namely when the indoor carbon dioxide concentration reaches the preset concentration threshold, the carbon dioxide in the indoor air is collected by the carbon dioxide collecting module 2, therefore, when the indoor carbon dioxide concentration does not exceed the standard, the filter element unit 7 is suitable for being placed in a closed space to avoid contacting with the air. Therefore, when the condition that the concentration of the indoor carbon dioxide exceeds the standard is met, the filter element unit 7 is driven to move to the carbon dioxide absorption position through the driving unit 8, namely to the proper position contacted with the indoor air, so that the carbon dioxide in the indoor air can be collected; and, when the indoor carbon dioxide concentration release condition is satisfied, the filter element unit 7 is driven by the driving unit 8 to move to the carbon dioxide release position so as to discharge the collected carbon dioxide to the outside by the vacuum pump 4.

In some embodiments, as shown in fig. 2, the means 10 for regulating the carbon dioxide concentration in the room further comprises a position detection module 9.

Specifically, the position detection module 9 is used for detecting the position information of the carbon dioxide collection module 2; the control module 5 is connected with the position detection module 9 and the driving unit 8, and is further configured to send a driving signal according to the position information to drive the filter element unit 7 to move.

In addition, in some embodiments, the status information includes the weight of the collected carbon dioxide, the status detection module 3 is a weight detection module for detecting the weight of the collected carbon dioxide, that is, the degree of carbon dioxide collection is determined by the change of the weight during the collection process, the content of the carbon dioxide collected by the carbon dioxide collection module increases as the detected weight value increases, and when it is determined that the weight of the collected carbon dioxide reaches a preset weight threshold, the collected carbon dioxide is in a saturated status. Wherein, the preset weight threshold value is a preset weight value after the carbon dioxide collection module is saturated in adsorption.

Or, the status information includes the concentration of carbon dioxide, the status detection module 3 is a concentration detection module, and is configured to detect the concentration of the collected carbon dioxide, that is, determine the collection degree of the carbon dioxide through the change of the concentration during the collection process, and as the detected concentration value increases, the content of the carbon dioxide collected by the carbon dioxide collection module increases, and when it is determined that the concentration of the carbon dioxide in the carbon dioxide collection module reaches a preset concentration threshold, it indicates that the collected carbon dioxide reaches a saturation state. The preset concentration threshold is a concentration value after the preset carbon dioxide collection module is saturated in adsorption.

It can be understood that when the status information includes the concentration of carbon dioxide, a concentration detection module can be separately arranged to detect the concentration of the collected carbon dioxide, or the collection module 1 can also be directly utilized, that is, the collection module 1 can collect the concentration of the indoor carbon dioxide and can also detect the concentration of the collected carbon dioxide, which is beneficial to reducing the cost.

Or, the state information includes a pressure value, the state detection module 3 is a pressure detection module to be used for detecting the pressure value of the carbon dioxide in the carbon dioxide collection module, that is, the collection degree of the carbon dioxide is judged through the change of the pressure in the collection process, along with the increase of the detected pressure value, the content of the carbon dioxide collected by the carbon dioxide collection module is increased, and when it is determined that the pressure value of the carbon dioxide in the carbon dioxide collection module reaches a second preset pressure threshold, it is indicated that the collected carbon dioxide reaches a saturated state. The second preset pressure threshold is a preset pressure value after the carbon dioxide collection module is saturated in adsorption.

Or the state information includes a wind speed value, the state detection module 3 is a speed detection module for detecting the wind speed value of the carbon dioxide collection module for collecting the carbon dioxide, that is, the collection degree of the carbon dioxide is judged through the change of the wind speed in the collection process, that is, the wind resistance of the carbon dioxide collected by the carbon dioxide collection module increases along with the decrease of the detected wind speed value, the content of the carbon dioxide collected by the carbon dioxide collection module increases, and when it is determined that the wind speed value of the carbon dioxide collected by the carbon dioxide collection module is smaller than the preset wind speed threshold, it is indicated that the collected carbon dioxide reaches a saturation state. The preset wind speed threshold value is a preset wind speed value after the carbon dioxide collection module is saturated in adsorption.

In a third embodiment of the present invention, an air conditioner 20 includes an indoor unit 11, an outdoor unit 12, and the device 10 for adjusting the concentration of carbon dioxide in a room provided in the above embodiment, as shown in fig. 3.

The device 10 for adjusting the indoor carbon dioxide concentration is arranged in the indoor unit, so that the device 10 for adjusting the indoor carbon dioxide concentration can improve the indoor carbon dioxide concentration, and the indoor air quality can reach the comfortable index of a user.

Specifically, in the operating state of the air conditioner 20, when it is determined that the indoor carbon dioxide concentration reaches the preset concentration threshold value, the apparatus 10 that can adjust the indoor carbon dioxide concentration moves to the air inlet of the indoor unit 11 to collect the carbon dioxide in the indoor air, and when it is determined that the weight of the collected carbon dioxide reaches the first preset weight threshold value, the apparatus 10 that can adjust the indoor carbon dioxide concentration moves to the carbon dioxide releasing position to discharge the collected carbon dioxide.

It is understood that, in the operating state of the air conditioner 20, the specific implementation manner of the air conditioner is similar to the specific implementation manner of the apparatus 10 for adjusting the indoor carbon dioxide concentration according to any of the above embodiments of the present invention, and please refer to the description of the portion of the apparatus 10 for adjusting the indoor carbon dioxide concentration specifically, and the description is omitted here for reducing redundancy.

In the embodiment, the indoor unit 11 includes an indoor heat exchanger and an indoor fan, and the outdoor unit 12 includes a compressor, an outdoor heat exchanger, and an outdoor fan.

The air conditioner 20 performs a cooling/heating cycle or a dehumidification function through a compressor, a condenser, an expansion valve, and an evaporator, and thus, it is possible to adjust an indoor environment and improve comfort of the indoor environment. The refrigeration cycle includes a series of processes, for example, involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.

The compressor compresses a refrigerant gas in a high temperature and high pressure state and discharges the compressed refrigerant gas, the discharged refrigerant gas flows into a condenser, the condenser condenses the compressed refrigerant into a liquid state, and heat is released to the surrounding environment through a condensation process.

The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner 20 can adjust the temperature of the indoor space throughout the cycle.

According to the air conditioner 20 of the embodiment of the invention, by adopting the device 10 for adjusting the indoor carbon dioxide concentration provided by the embodiment, the indoor carbon dioxide concentration can be effectively reduced, and the indoor air quality can reach the comfortable index of a user.

Step S5, detecting carbon dioxide (CO)₂) And (4) concentration.

And step S6, judging whether the concentration exceeds the standard, namely judging whether the indoor carbon dioxide concentration reaches a preset concentration threshold. If yes, go to step S7; if not, step S5 is executed.

And step S7, the driving unit sends the filter element unit to an air inlet of the indoor unit.

Step S8, collecting carbon dioxide in the indoor air.

And step S9, judging whether the filter element unit is saturated or not. If yes, go to step S10; if not, step S8 is executed.

In step S10, the driving unit brings the filter element unit into the carbon dioxide releasing position.

And step S11, determining that the filter element unit reaches the carbon dioxide release position, and starting a vacuum pump.

Step S12, the cartridge unit releases carbon dioxide.

In step S13, a pressure value P inside the filter element unit is detected.

Step S14, judging whether the pressure value P is larger than a first preset pressure threshold value P_{First stage}. If so, go to step S12, otherwise, go to step S15.

Step S15, determining that the pressure value P is less than or equal to a first preset pressure threshold value P_{First stage}。

In step S16, after the carbon dioxide is released, the vacuum pump is turned off, and step S5 is executed.

Therefore, based on the above steps, the air conditioner 20 according to the embodiment of the present invention can control the apparatus 10 for adjusting the indoor carbon dioxide concentration to collect the carbon dioxide in the indoor air when the indoor carbon dioxide concentration reaches a certain standard, and can discharge the collected carbon dioxide to the outside by using the transmission function of the vacuum pump, so as to effectively reduce the indoor carbon dioxide concentration, ensure that the indoor carbon dioxide concentration is maintained within a reasonable range, which is beneficial to the health of the user and improves the user experience.
