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 of adjusting the carbon dioxide concentration in a room according to an embodiment of the present invention will be described with reference to the accompanying drawings, which at least includes steps S1 to S4, as shown in fig. 1.
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 value, and collecting the carbon dioxide in the indoor air.
The preset concentration threshold value can be understood as the 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.
Step S3, the weight of the collected carbon dioxide is acquired.
In an embodiment, a weight sensor may be provided to detect the weight of the collected carbon dioxide.
And step S4, determining that the weight of the collected carbon dioxide reaches a first preset weight threshold value, and discharging the collected carbon dioxide to the outside.
The first preset weight threshold value can be understood as a preset maximum allowable weight value for collecting carbon dioxide. The first preset weight threshold may be set according to actual conditions, which is not limited in this respect.
In an embodiment, in order to ensure that the concentration of the indoor carbon dioxide is maintained within a range beneficial to the health of a user, the embodiment of the invention determines the degree of collection of the indoor carbon dioxide in the process of collecting the carbon dioxide in the indoor air by detecting the weight of the collected carbon dioxide in real time and comparing the detected weight with a first preset weight threshold value, so that the content of the carbon dioxide remaining in the indoor air can be maintained within the range of the health index of the user on the indoor air quality when the weight of the collected carbon dioxide is determined to reach the first preset weight threshold value.
Specifically, the method of the embodiment of the invention detects the weight of the collected carbon dioxide in real time, and if the weight of the collected carbon dioxide is determined to reach a first preset weight threshold, it is indicated that the weight of the collected carbon dioxide is saturated, and the content of the carbon dioxide remaining after the carbon dioxide in the indoor air is collected this time meets the user comfort index, so that the collected carbon dioxide is discharged to the outdoor, and the next collection operation of the indoor carbon dioxide is facilitated; if the weight of the collected carbon dioxide is determined not to reach the first preset weight threshold, it is indicated that the weight of the collected carbon dioxide is not saturated, and the content of the carbon dioxide in the indoor air is still in an overproof state. 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 proved, and the method is not beneficial to the health of a user.
In some embodiments, the collected carbon dioxide is released by heating a carbon dioxide collecting module for collecting carbon dioxide, and the released carbon dioxide is discharged to the outside, wherein during the release of the collected carbon dioxide, the weight of the released carbon dioxide is obtained in real time, so as to determine the release degree of the carbon dioxide through the detected change of the weight, and when it is determined that the weight of the released carbon dioxide reaches a second preset weight threshold, the discharging is completed.
The second predetermined weight threshold value is understood to be a predetermined weight value that ensures complete release of carbon dioxide. The first preset weight threshold may be set according to actual conditions, which is not limited in this respect.
Specifically, the method of the embodiment of the invention detects the weight of released carbon dioxide in real time, and if the weight of released carbon dioxide is determined to reach a second preset weight threshold, it is determined that the release of the weight of the collected carbon dioxide is completed; if the weight of the released carbon dioxide is determined not to reach the second preset weight threshold, the weight of the collected carbon dioxide is not completely released outdoors, and the carbon dioxide needs to be released continuously so as to be used for the next indoor carbon dioxide collecting operation.
In some embodiments, the carbon dioxide release degree of the carbon dioxide collection module is determined by obtaining the total weight of the carbon dioxide collection module, namely, the carbon dioxide in the indoor air is absorbed by the carbon dioxide collection module, performing the release work after the carbon dioxide collection module is saturated in absorption, detecting the total weight of the carbon dioxide collection module in real time during the release process of the carbon dioxide collection module, and calculating the weight difference between the total weight and the initial weight of the carbon dioxide collection module, namely, the weight when the carbon dioxide collection module does not absorb the carbon dioxide, as the weight of the released carbon dioxide.
In some embodiments, the heating temperature of the carbon dioxide collection module is monitored, and when the heating temperature is lower than the preset carbon dioxide release temperature, the heating temperature does not reach the temperature condition that the carbon dioxide collection module releases carbon dioxide, so that the heating temperature is increased and continuously monitored, the carbon dioxide collection module reaches the temperature condition that the carbon dioxide is released, that is, the heating temperature reaches the preset carbon dioxide release temperature, the carbon dioxide collection module is controlled at the constant temperature by the heating temperature, the carbon dioxide collection module releases the absorbed carbon dioxide, and the purpose of discharging the carbon dioxide exceeding the standard in the indoor air to the outdoor so as to reduce the content of the indoor carbon dioxide is achieved.
In some embodiments, because the temperature control has a hysteresis problem, in the embodiments of the present invention, when the temperature difference between the heating temperature and the preset carbon dioxide release temperature is less than or equal to the preset temperature return difference, it may be determined that the carbon dioxide collection module reaches the temperature condition for releasing carbon dioxide, so as to improve the accuracy of temperature control and the degree of release of carbon dioxide.
According to a second aspect of the present invention, an apparatus for adjusting indoor carbon dioxide concentration is provided, as shown in fig. 2, an apparatus 10 for adjusting indoor carbon dioxide concentration includes a collection module 1, a carbon dioxide collection module 2, a weight detection module 3, and a control module 4.

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.
