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 a fresh air air conditioner. Background Art

[0002] Air conditioners are widely used in thousands of households as devices for regulating indoor temperature. Generally speaking, air conditioners regulate indoor temperature. As a closed system, indoor heat exchange with the outside environment should be minimized to reduce indoor energy loss. However, if a closed system does not exchange energy with the outside world for a long time, it will inevitably cause internal environmental disorder, which is usually manifested as problems such as decreased indoor air quality and decreased oxygen concentration. Decreased indoor air quality usually leads to human discomfort, as well as hypoxia, decreased human metabolism, decreased immunity and many other problems.

[0003] With the development of the air conditioning industry, new oxygen-generating air conditioners and fresh air conditioners are gradually coming into people's view. Oxygen-generating air conditioners are oxygen-generating equipment installed in outdoor units, which input oxygen into the room through pipes following the path of the air conditioning piping; fresh air conditioners are bellows connected to the indoor and outdoor areas, which, driven by the fresh air centrifugal blades, introduce fresh air from the outdoors into the room.

[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 outdoors into the indoor space. 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 with fresh air, the oxygen input into the room by the oxygen generator has an oxygen content of 21% in general air, so the oxygen input flow rate only needs to be 21% of the fresh air input flow rate to meet the needs of the human body indoors. Although a small amount of oxygen needs to be input into the room to ensure a stable oxygen content in the room, oxygen is not natural air after all and cannot completely replace natural air.

[0006] Therefore, how to combine oxygen-generating air conditioners with fresh air air conditioners to meet people's needs for fresh indoor air and avoid large indoor energy losses as much as possible 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 and indoor heat loss can be avoided, so as to solve the above-mentioned technical problems existing in the prior art.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0009] A control method for a fresh air air conditioner provided by the present invention first controls the fresh air air conditioner to switch to the indoor linkage purification mode before starting control; the control method includes the following steps:

[0013] When the judgment result is that the outdoor air quality is good, continue to judge the size of the indoor and outdoor temperature difference;

[0014] Based on the judged temperature difference, control the fresh air module and the oxygen generation module in the fresh air controller to operate in linkage.

When the outdoor temperature is very cold or very hot, a large amount of fresh air entering from the outside will consume the indoor heat and cold. The two are linked to find a suitable indoor oxygen enrichment scheme, and can realize automatic detection of indoor and outdoor air quality. The air quality (oxygen content) of the air conditioner and the oxygen input are linked to adjust, while improving the air quality (oxygen content) in the room, maintaining the clean air enriched with oxygen in the room, reducing the heat loss in the room, avoiding drastic temperature fluctuations in the room, saving energy and reducing consumption, and improving user comfort.

[0045] Figure 3 It is a system composition diagram of the control device of the present invention. DETAILED DESCRIPTION

[0046] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0047] like Figure 1 As shown, the present invention provides a control method for a fresh air air conditioner, which performs linkage adjustment on the fresh air and oxygen input of the air conditioner, while improving the air quality (oxygen content) in the room, reducing the heat loss in the room, avoiding the drastic temperature fluctuation in the room, and improving the user comfort; firstly, the fresh air air conditioner is controlled to switch to the indoor linkage purification mode; it should be noted that the fresh air 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 air conditioner leaves the factory, for example, preset maximum temperature difference Y0, preset minimum temperature difference Y, preset dust particles W0, preset minimum oxygen concentration X; some operating parameters also need to be preset, such as the first power P1, the second power P2, the first oxygen delivery speed Q1, the second oxygen delivery speed Q2, and the third oxygen delivery speed Q3;

[0051] Step S2: Based on the obtained indoor and outdoor parameters, determine the outdoor air quality. Specifically, determine the magnitude relationship between the outdoor dust particle PM2.5 value W2 and the preset dust particle W0.

[0052] When the outdoor dust particle PM2.5 value W2 > the preset dust particle W0, it is determined that the outdoor air quality is poor.

[0053] When the outdoor dust particle PM2.5 value W2 ≤ the preset dust particle W0, it is determined that the outdoor air quality is good.

[0054] Step S3: When the judgment result is that the outdoor air quality is poor, that is, when the outdoor dust particle PM2.5 value W2 > the preset dust particle W0, at this time, due to the poor outdoor air quality, it is not suitable to introduce fresh air. Therefore, control the oxygen generation module in the fresh air air conditioner to operate at the oxygen delivery speed Q2, and the fresh air module does not start.

[0055] Step S4: When the judgment result is that the outdoor air quality is good, that is, when the outdoor dust particle PM2.5 value W2 ≤ the preset dust particle W0, at this time, the outdoor air quality is good and fresh air can be introduced. However, it is necessary to compare the indoor and outdoor temperature differences to avoid losing indoor cooling or heating. Therefore, continue to judge the magnitude of the indoor and outdoor temperature differences.

[0056] The magnitude of the indoor and outdoor temperature difference refers to comparing 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 average. 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 introducing outdoor fresh air will cause indoor heat loss and large temperature fluctuations, and it is not suitable to introduce fresh air. If the temperature difference is average, it indicates that introducing fresh air will have a certain impact, but the impact is not significant. At this time, fresh air should be introduced in a small amount. If the temperature difference is small, it indicates that introducing fresh air has basically no impact, and fresh air can be introduced normally or in a large amount.

[0057] Step S5: Based on the judged magnitude of the temperature difference, control the fresh air module and the oxygen generation module in the fresh air controller to operate in联动.

[0058] Specifically, based on the judged magnitude of the temperature difference, controlling the fresh air module and the oxygen generation module in the fresh air controller to operate in联动 includes:

[0059] When the preset minimum temperature difference Y < |indoor temperature Y1 - outdoor temperature Y2| < the preset maximum temperature difference Y0, it indicates that introducing outdoor fresh air will not cause excessive heat loss, and fresh air can be introduced in a small amount. Then control the fresh air module in the fresh air air conditioner to operate at the first power P1 and the oxygen generation module to operate at the second oxygen delivery speed Q2.

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

[0061] When |Indoor temperature Y1-outdoor temperature Y2|≤preset minimum temperature difference Y, it indicates that the indoor and outdoor temperature difference is very small, and the introduction of fresh air will not cause heat loss, and a large amount of fresh air can be introduced. Therefore, the fresh air module in the fresh air air conditioner is controlled to operate at the second power P2, and the oxygen production module is controlled to operate at the first oxygen delivery speed Q1;

[0062] Among them, 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 air conditioner provided by the present invention combines the fresh air module of the air conditioner with the oxygen production module, and the indoor oxygen supply and fresh air are linked. When the outdoor temperature is very cold or very hot, a large amount of fresh air entering from the outside will consume the indoor heat and cold. The two are linked to find a suitable indoor oxygen enrichment scheme, and can realize automatic detection of indoor and outdoor air quality. The air quality (oxygen content) of the air conditioner and the oxygen input are linked to adjust, while improving the air quality (oxygen content) in the room, maintaining the clean air enriched with oxygen in the room, reducing the heat loss in the room, avoiding drastic temperature fluctuations in the room, saving energy and reducing consumption, and improving user comfort.

[0064] As a further improvement of the present invention, the oxygen production module in the fresh air air conditioner is controlled to operate according to the second oxygen delivery speed Q2, and after the fresh air module is not started, the method further includes:

[0065] Compare 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 supplementation is required, 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 ≥ the preset minimum oxygen concentration X, it indicates that the indoor oxygen concentration has reached the standard, and the process returns to the step of obtaining indoor and outdoor air parameters to continue monitoring the outdoor air quality.

[0068] As a further improvement of the present invention, after controlling the fresh air module in the fresh air air conditioner to operate at the first power P1 and the oxygen production module to operate at the second oxygen delivery speed Q2, or controlling the fresh air module in the fresh air air conditioner to operate at the second power P2 and the oxygen production module to operate at the first oxygen delivery speed Q1, the method further includes:

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

[0070] When the indoor oxygen concentration X1> the preset minimum oxygen concentration X, the process returns to the step of obtaining indoor and outdoor air parameters to continue monitoring the outdoor air quality;

[0071] When the indoor oxygen concentration X1 ≤ the preset minimum oxygen concentration X, the fresh air module is controlled to operate at the power P2 and the oxygen production module is controlled to operate at the third oxygen delivery speed Q3.

[0072] As a further improvement of the present invention, after controlling the fresh air module to operate at the second power P2 and the oxygen production module to operate at the third oxygen delivery speed Q3, the process returns to the step of obtaining indoor and outdoor air parameters.

[0109] A fresh air air conditioner provided by the present invention includes a fresh air module and an oxygen generation module; the fresh air module and the oxygen generation module can operate联动, and are used to execute the above control method.

[0110] Embodiment 1:

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

[0112] The user turns on the fresh air and oxygen generation linkage mode, and the air detection module of the fresh air 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 it is transmitted to the analysis and control module of the fresh air air conditioner and compared with the preset limit values set at the time of the air conditioner factory, including the preset minimum oxygen concentration X, the preset minimum temperature difference Y < the preset maximum temperature difference Y0, and the preset dust particle W0; the fresh air power 0 ≤ P0 < P1 < P2, and the oxygen delivery rate Q1 < Q2 < Q3.

[0113] The analysis and 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, i.e., the outdoor air quality is poor, the fresh air function is not turned on, the power P0 = 0, and the oxygen generation function is turned on to operate at the second oxygen delivery rate Q2; then the program collects the indoor oxygen concentration X1 and compares it with the preset minimum oxygen concentration X set by the program. When X1 ≤ X, the oxygen generation power is increased and the oxygen delivery rate is increased to the third oxygen delivery rate Q3 (Q3 > Q2). When X1 > X and the indoor oxygen concentration meets the minimum standard, the oxygen delivery rate remains unchanged, and the outdoor PM2.5 concentration is continuously monitored.

[0115] When W2 ≤ W0 and the outdoor air quality is good, then the program collects the indoor-outdoor temperature difference. When |Y1 - Y2| ≥ Y0 and the indoor-outdoor temperature difference is too large, the fresh air is not turned on, and only the oxygen generation function is turned on at the second oxygen delivery rate Q2; the subsequent program is the same as above.

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

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

[0118] By comparing the indoor oxygen concentration, when X1 < X, the fresh air power is increased to P2 and the oxygen delivery rate is increased to Q3; when X1 ≥ X, the fresh air and oxygen delivery remain unchanged, and the outdoor PM2.5 concentration is continuously monitored.

[0119] The fresh air air conditioner of the present invention combines a fresh air module and an oxygen generation module, and the indoor oxygen delivery and fresh air are linked. When the outdoor temperature is very cold or very hot, introducing a large amount of fresh air from the outside will consume the indoor cooling and heating energy. The two are linked to find a suitable indoor oxygen-rich solution, which can automatically detect the indoor and outdoor air quality, maintain the oxygen-rich clean air indoors, avoid indoor cooling and heating energy loss, and achieve the functions of energy conservation and consumption reduction.
