Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a control method, device, medium, electronic equipment and fresh air air conditioner of a fresh air air conditioner. Background Art

[0002] Air conditioners, as devices for regulating indoor temperature, are widely used in countless households. Generally speaking, air conditioners regulate indoor temperature. As a closed system, the indoor environment should minimize heat exchange with the outside world to reduce indoor energy loss. However, prolonged periods of inactivity in a closed system inevitably lead to environmental disturbances, typically manifesting as decreased indoor air quality and oxygen concentration. This deterioration in indoor air quality often leads to discomfort, hypoxia, decreased metabolism, and weakened immunity, among other issues.

[0003] With the development of the air conditioning industry, new oxygen-generating air conditioners and fresh air air conditioners are gradually becoming popular. Oxygen-generating air conditioners install oxygen generators in outdoor units, which deliver oxygen indoors via pipes that follow the path of the air conditioning piping. Fresh air conditioners use bellows that connect indoor and outdoor air, driven by centrifugal impellers, to draw fresh air indoors.

[0004] Since the oxygen content in outdoor fresh air accounts for 21%, the fresh air needs to work continuously to ensure that the oxygen content in indoor air conditioning reaches the value required by the human body. However, the uninterrupted operation of the fresh air system and the heat difference between indoor and outdoor air usually cause fresh air air conditioning to input a large amount of air from the outdoors into the indoors. The introduction of outdoor air will inevitably lead to a series of problems such as indoor heat loss, increased air conditioning load, and even unstable indoor temperature.

[0005] Compared to fresh air, the oxygen supplied by the oxygen concentrator is 21% oxygen. Since normal air contains 21% oxygen, the oxygen input flow rate only needs to be 21% of the fresh air input flow rate to meet indoor human needs. Although a small amount of oxygen is needed to maintain a stable indoor oxygen content, oxygen is not natural air and cannot completely replace it.

[0006] Therefore, how to combine oxygen-generating air conditioning with fresh air air conditioning to meet people's needs for fresh indoor air while minimizing large indoor energy losses requires a solution that links the two. Summary of the Invention

[0007] The purpose of the present invention is to provide a control method, device, medium, electronic equipment and fresh air air conditioner for fresh air and oxygen production linkage, so that fresh air can be obtained indoors while avoiding indoor heat loss, so as to solve the above-mentioned technical problems existing in the prior art.

[0046] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described in detail below. Obviously, the described embodiments only represent some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0047] As shown in Figure 1 , the present application provides a control method of a fresh air conditioner, which links and adjusts the input amounts of fresh air and oxygen of the air conditioner, reduces the heat loss in the room while improving the air quality (oxygen content) in the room, avoids the severe temperature fluctuation in the room, and improves the user comfort; first, the fresh air conditioner is controlled to switch to the indoor linkage purification mode; it should be noted that the fresh air conditioner includes a fresh air module and an oxygen production module;

[0048] Specifically, the control method includes the following steps:

[0049] Step S1, obtaining indoor and outdoor air parameters; wherein the indoor and outdoor air parameters include indoor oxygen concentration X1, indoor temperature Y1, outdoor temperature Y2, and outdoor dust particle PM2.5 value W2.

[0050] It should be noted that some comparison parameter values need to be set when the fresh air conditioner is factory-finished, for example, a preset maximum temperature difference Y0, a preset minimum temperature difference Y, a preset dust particle W0, and a preset minimum oxygen concentration X; some operation parameters also need to be preset, such as a first power P1, a second power P2, a first oxygen delivery speed Q1, a second oxygen delivery speed Q2, and a third oxygen delivery speed Q3;

[0051] Step S2, based on the obtained indoor and outdoor parameters, judging the outdoor air quality; specifically, judging the size of the outdoor dust particle PM2.5 value W2 and the preset dust particle W0;

[0052] When the outdoor dust particle PM2.5 value W2 is greater than the preset dust particle W0, it is judged that the outdoor air quality is poor;

[0053] When the outdoor dust particle PM2.5 value W2 is less than or equal to the preset dust particle W0, it is judged that the outdoor air quality is good.

[0054] Step S3, when the judgment result is that the outdoor air quality is poor, that is, the outdoor dust particle PM2.5 value W2 is greater than the preset dust particle W0, at this time, due to the poor outdoor air quality, it is not suitable to introduce fresh air, so the oxygen production module in the fresh air conditioner is controlled to operate at the oxygen output speed Q2, and the fresh air module is not started;

[0055] Step S4, when the judgment result is that the outdoor air quality is good, that is, the outdoor dust particle PM2.5 value W2 is less than or equal to the preset dust particle W0, at this time, the outdoor air quality is good, and fresh air can be introduced, but indoor and outdoor temperature difference comparison needs to be made to avoid loss of indoor cold or heat, so the size of the indoor and outdoor temperature difference is further judged;

[0056] The size of the indoor and outdoor temperature difference refers to the comparison of the indoor and outdoor temperature difference value with the preset maximum temperature difference and minimum temperature difference to see which interval the temperature difference value falls into. If the temperature difference value is less than the minimum temperature difference, the temperature difference is small, if it falls between the minimum temperature difference and the maximum temperature difference, the temperature difference is general, and if the temperature difference value is greater than the maximum temperature difference, the temperature difference is large. If the indoor and outdoor temperature difference is large and exceeds a set limit temperature difference value, it indicates that the introduction of outdoor fresh air will cause loss of indoor heat and cause large temperature fluctuations, which is not suitable for introducing fresh air. If the temperature difference is general, it indicates that the introduction of fresh air will have some impact, but the impact is not large, at this time, the fresh air should be introduced in small amount, and if the temperature difference is small, it indicates that the introduction of fresh air has little impact, and the fresh air can be introduced in normal amount or large amount;

[0057] Step S5, based on the size of the temperature difference judged, the fresh air module and the oxygen production module in the fresh air controller are controlled to operate in linkage.

[0058] Specifically, based on the size of the temperature difference judged, the fresh air module and the oxygen production module in the fresh air controller are controlled to operate in linkage, including:

[0059] When the preset minimum temperature difference Y is less than the absolute value of the indoor temperature Y1 minus the outdoor temperature Y2 and the preset maximum temperature difference Y0, it indicates that the introduction of outdoor fresh air will not cause excessive heat loss, and a small amount of fresh air can be introduced, so the fresh air module in the fresh air conditioner is controlled to operate at the first power P1, and the oxygen production module is controlled to operate at the second oxygen output speed Q2;

[0060] When the indoor temperature Y1-outdoor temperature Y2 is greater than or equal to the preset maximum temperature difference Y0, it indicates that introducing fresh air will cause a large amount of heat loss, and cannot be introduced, so the oxygen production module in the fresh air conditioner is controlled to operate at the second oxygen supply speed Q2, and the fresh air module is not started;

[0061] When the indoor temperature Y1-outdoor temperature Y2 is less than or equal to the preset minimum temperature difference Y, it indicates that the indoor and outdoor temperature difference is very small, and introducing fresh air will not cause heat loss, and can be introduced in a large amount, so the fresh air module in the fresh air conditioner is controlled to operate at the second power P2, and the oxygen production module is controlled to operate at the first oxygen supply speed Q1.

[0062] Wherein, the first power P1 is less than the second power P2, and the first oxygen supply speed Q1 is less than the second oxygen supply speed Q2.

[0063] The control method of the fresh air conditioner provided by the application combines the fresh air module and the oxygen production module of the air conditioner, and the indoor oxygen supply and fresh air linkage, when the outdoor temperature is very cold or very hot, a large amount of fresh air from the outdoor will cause the loss of indoor cold and heat, and the two linkages find the appropriate indoor oxygen enrichment scheme, which can realize the automatic detection of indoor and outdoor air quality, the linkage adjustment of the air conditioning fresh air and oxygen input, the improvement of the room air quality (oxygen content), the maintenance of the indoor oxygen-enriched clean air, the reduction of the room heat loss, the avoidance of the room temperature fluctuation, the energy saving and consumption reduction, and the improvement of the user comfort.

[0064] As a further improvement of the application, after the oxygen production module in the fresh air conditioner is controlled to operate at the second oxygen supply speed Q2 and the fresh air module is not started, the method further comprises:

[0065] Comparing the indoor oxygen concentration X1 with the preset minimum oxygen concentration X;

[0066] When the indoor oxygen concentration X1 is less than the preset minimum oxygen concentration X, it indicates that the indoor oxygen concentration is insufficient, and oxygen supplement is needed, so the oxygen production module is controlled to operate at the third oxygen supply speed Q3; wherein, the third oxygen supply speed Q3 is greater than the second oxygen supply speed Q2.

[0067] When the indoor oxygen concentration X1 is greater than or equal to the preset minimum oxygen concentration X, it indicates that the indoor oxygen concentration has reached the standard, and the step of acquiring the indoor and outdoor air parameters is returned to continue monitoring the outdoor air quality.

[0068] As a further improvement of the application, after the fresh air module in the fresh air conditioner is controlled to operate at the first power P1 and the oxygen production module is controlled to operate at the second oxygen supply speed Q2, or the fresh air module in the fresh air conditioner is controlled to operate at the second power P2 and the oxygen production module is controlled to operate at the first oxygen supply speed Q1, the method further comprises:

[0069] Comparing the indoor oxygen concentration X1 with the preset minimum oxygen concentration X;

[0070] When the indoor oxygen concentration X1>X, the preset minimum oxygen concentration X is returned to the step of acquiring indoor and outdoor air parameters, and the outdoor air quality is continuously monitored.

[0071] When the indoor oxygen concentration X1≤X, the preset minimum oxygen concentration X is returned to the step of acquiring indoor and outdoor air parameters, and the outdoor air quality is continuously monitored.

[0072] As a further improvement of the application, after the new air module is controlled to operate at the second power P2 and the oxygen generating module is controlled to operate at the third oxygen delivery speed Q3, the step of acquiring indoor and outdoor air parameters is returned.

[0110] Embodiment 1:

[0111] As shown in the figure, the control method of the fresh air conditioner of the present application is: Figure 2

[0112] The user starts the fresh air and oxygen linkage mode, the air detection module of the fresh air conditioner starts to detect the indoor air parameters, including the indoor oxygen concentration X1, the indoor temperature Y1, the outdoor temperature Y2 and the outdoor dust particle PM2.5 value W2. Then, the parameters are transmitted to the analysis control module of the fresh air conditioner, and compared with the limit values preset at the factory, including the preset minimum oxygen concentration X, the preset minimum temperature difference Y0 and the preset maximum temperature difference Y0, and the preset dust particle W0; the fresh air power 0≤P0

[0113] The analysis control module first detects the outdoor dust particle PM2.5 value W2 and compares it with the preset dust particle W0 set by the program;

[0114] ​When W2>W0, the outdoor air quality is poor, the fresh air function is not started, the power P0=0, the oxygen production function is started to run according to the second oxygen supply rate Q2; then the program collects the indoor oxygen concentration X1, and compares it with the program set value preset minimum oxygen concentration X, when X1≤X, the oxygen production power is increased, the oxygen supply rate is increased to the third oxygen supply rate Q3 (Q3>Q2), when X1>X, the indoor oxygen concentration meets the minimum standard, the oxygen supply rate is unchanged, and the outdoor PM2.5 concentration is continuously monitored.

[0115] When W2≤W0, the outdoor air quality is good, then the program collects the indoor and outdoor temperature difference, when |Y1-Y2|≥Y0, the indoor and outdoor temperature difference is too large, the fresh air is not started, and only the oxygen production function is started according to the second oxygen supply rate Q2; the following program is the same as above.

[0116] When W2≤W0, the outdoor air quality is good, the program collects the indoor and outdoor temperature difference. When Y<|Y1-Y2|<Y0, there is a small temperature difference between the indoor and outdoor, the fresh air is started with a small power P1, and the second oxygen supply rate Q2;

[0117] When W2≤W0, the outdoor air quality is good, the program collects the indoor and outdoor temperature difference. |Y1-Y2|≤Y, the indoor and outdoor temperature difference is very small, the fresh air is started with a large power P2, and the first oxygen supply rate Q1.

[0118] When X1<X, the fresh air power is increased P2, and the oxygen supply rate is increased Q3; when X1≥X, the fresh air and the oxygen supply are unchanged, and the outdoor PM2.5 concentration is continuously monitored.

[0119] The fresh air conditioner of the application combines the fresh air module and the oxygen production module, and the indoor oxygen supply and the fresh air linkage. When the outdoor temperature is very cold or very hot, a large amount of fresh air from the outdoor will consume the indoor cold and heat, and the linkage of the two can find a suitable oxygen-rich scheme in the indoor, so that the air quality indoors and outdoors can be automatically detected, the indoor clean air with high oxygen content can be maintained, the indoor cold and heat loss can be avoided, and the energy saving and consumption reduction function can be realized.

[0120] The above is only a specific embodiment of the application, but the protection scope of the application is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the application, which should be covered within the protection scope of the application. Therefore, the protection scope of the application should be subject to the protection scope of the claims.
