Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to a control method, device, medium, electronic equipment, and air conditioner for an air conditioner. Background Technology

[0002] In winter environments, for open or semi-open spaces requiring heating, achieving overall temperature control is difficult due to constant heat and mass exchange with the low-temperature external environment. Furthermore, current air conditioning operating logic often results in prolonged high-frequency operation of the air conditioner, leading to poor user comfort and energy waste, as the indoor temperature rarely reaches the set temperature. Therefore, this patent addresses this issue by adding a personalized heating and airflow mode for open or semi-open spaces requiring heating. In this mode, the air conditioner no longer uses the detected inner ring temperature as the determining factor but instead relies on user settings. Based on these settings, an initial operating frequency is calculated. After a period of stable operation, the target inner pipe temperature built into the set mode is used as the basis for fuzzy control of the air conditioner's operating frequency. Summary of the Invention

[0003] The purpose of this invention is to provide a control method, device, medium, electronic equipment and air conditioner for an air conditioner, so as to solve the technical problems of poor comfort, low energy efficiency and energy waste in open or semi-open places when heating.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] This invention provides a control method for an air conditioner, wherein the air conditioner is installed in an open or semi-open space and is used to provide heating for the open or semi-open space; the method includes:

[0006] Calculate the initial operating frequency f0;

[0007] According to the calculated initial operating frequency f0, control the air conditioner to run for a first set time t1;

[0008] Obtain the temperature difference ΔT between the inner tube and the outer tube.

[0009] The obtained inner tube temperature difference ΔT is compared with the preset inner tube temperature difference range [T1,T2].

[0010] Based on the comparison results, different fuzzy control steps are performed on the compressor operating frequency f.

[0011] The air conditioner control method of the present invention determines the initial operating frequency of the compressor based on the inner ring, the user-set temperature and fan speed. After the operation is stable, the compressor operating frequency is fuzzy controlled by comparing the difference between the inner pipe temperature and the preset target inner pipe temperature. It does not require heating the entire open space. By operating the compressor at a low frequency, it delivers air that is slightly higher than the human skin temperature, which can satisfy human comfort and achieve energy-saving operation.

[0012] Based on the above technical solution, the present invention can be further improved as follows.

[0013] As a further improvement of the present invention, the initial operating frequency f0 is calculated using the following formula:

[0014] f0=fR+fF+A*(T 外-max -T 外环 )+B*(T 内-max –T 内环 )+C; where:

[0015] f0 is the rounded integer;

[0016] fR is the conversion frequency corresponding to each heat level;

[0017] fF is the calculated frequency corresponding to each windshield;

[0018] T 外-max The highest outer ring temperature corresponding to the air conditioner's heating operation;

[0019] T 外环 This refers to the current outer ring temperature.

[0020] T 内-max This refers to the highest inner ring temperature corresponding to the air conditioner's heating operation.

[0021] T 内环 This is the current inner ring temperature;

[0022] A is the outer ring conversion factor;

[0023] B is the inner ring conversion factor;

[0024] C is the frequency correction value, and its calculation formula is: C = f min -fR -适中 -fF -弱 , where f min This refers to the minimum frequency at which the air conditioner operates in heating mode; fR -适中 The conversion frequency corresponding to moderate heat; fF -弱 This is the calculated frequency corresponding to the low wind setting.

[0025] As a further improvement of the present invention, the first set time t1 is 20 min.

[0026] As a further improvement of the present invention, the temperature difference ΔT of the inner tube is calculated using the following formula:

[0027] Inner tube temperature difference ΔT=T 目标内管温 -T 当前内管温 Among them, T 目标内管温 The following formula is used to obtain it;

[0028] T 目标内管温 =T 内环 +T X-R +T X-F Among them, T X-R Temperature correction for thermal sensing; T X-F Adjust the temperature for the fan.

[0029] As a further improvement of the present invention, the step of performing different fuzzy control steps on the compressor operating frequency f based on the comparison results includes:

[0030] When the temperature difference ΔT in the inner tube is within the preset temperature difference range [T1,T2] and is stably maintained for the second set time t2, or after the temperature difference ΔT in the inner tube undergoes several alternating positive and negative fuzzy inferences, the fuzzy control step for the stable period of the inner tube temperature is executed.

[0031] Otherwise, execute the fuzzy control steps for the unstable period of the internal pipe temperature.

[0032] As a further improvement of the present invention, when calculating the stable maintenance time within the preset inner tube temperature difference ΔT ∈ [T1, T2], if the inner tube temperature difference ΔT exceeds the preset inner tube temperature difference range [T1, T2], the stable maintenance time is reset to zero and recalculated; or, when calculating the number of alternating changes in the positive and negative directions, if the inner tube temperature difference ΔT exceeds the preset inner tube temperature difference range [T1, T2], the number of alternating changes is reset to zero and recalculated, and multiple consecutive changes in the positive or negative directions are not accumulated.

[0033] As a further improvement of the present invention, the step of performing fuzzy control during the stabilization period of the inner tube temperature includes:

[0034] The time t required to obtain the temperature change T3 of the inner tube 变 The temperature change of the inner tube, T3, is within the preset temperature difference range of the inner tube [T1, T2].

[0035] Based on the required time t for acquisition 变 Determine the fuzzy control frequency value Δf;

[0036] Based on the determined fuzzy control frequency value Δf, the compressor control frequency f is obtained; where,

[0037] f = f 当前运行频率 +Δf;

[0038] The compressor is controlled to operate at a control frequency f.

[0039] As a further improvement of the present invention, the step of performing fuzzy control of the internal pipe temperature during the unstable period includes:

[0040] The time t required to obtain the temperature change T3 of the inner tube is determined; where the temperature change T3 of the inner tube ∈ the preset temperature difference range of the inner tube [T1,T2].

[0041] Based on the required time t for acquisition 变 Determine the fuzzy control frequency value Δf;

[0042] Based on the determined fuzzy control frequency value Δf, the compressor control frequency f is obtained; where,

[0045] The control method of the present invention is designed for open or semi-open spaces with heating needs. Based on user-defined settings, the compressor can create a thermal environment that meets user needs and achieve energy-saving operation by operating at low frequency.

For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0057] Figure 1 This is a control flowchart of the air conditioner control method of the present invention;

[0058] Figure 2 This is a control logic diagram of one embodiment of the air conditioner control method of the present invention;

[0059] Figure 3 This is a system composition diagram of the control device of the present invention. Detailed Implementation

[0060] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0061] like Figure 1 and Figure 2As shown, this invention provides a control method for an air conditioner. The air conditioner used in this method is installed in an open or semi-open space and is used to heat that space. In conventional control methods, for open or semi-open spaces where only a localized area requires heating, the original air conditioning heating mode is still executed. This requires heating the entire target area, which can easily lead to prolonged high-frequency operation of the compressor, still failing to meet the heating demand. Therefore, this invention, targeting open or semi-open spaces where only a localized area requires heating, introduces a personalized heating and airflow mode based on human needs. In this personalized heating and air supply mode, users can freely set their heating requirements (e.g., R1 to R3, i.e., moderate, slightly warm, warm) and fan speed (F1 to F5, i.e., weak, weak, medium, strong, strong). Of course, more heating requirement levels and fan speeds can also be set. The above is just an example illustration, and can be set according to actual needs. The personalized heating and air supply mode will set the initial operating frequency (suitable initial operating frequency) of the air conditioner compressor based on the current inner ring temperature, outer ring temperature, user-set heating and fan speed. After the indoor fan starts for t1 minutes (t1 recommended value is 20 minutes), it exits the initial frequency control and enters fuzzy control.

[0062] Specifically, the control method for the personalized heating and air supply mode of the air conditioner of the present invention includes:

[0063] Step S1: Calculate the initial operating frequency f0;

[0064] The initial operating frequency f0 is calculated using the following formula:

[0065] f0=fR+fF+A*(T 外-max -T 外环 )+B*(T 内-max –T 内环 )+C; where:

[0066] f0 is an integer after rounding. If the calculated initial operating frequency f0 is not an integer, if its decimal part is less than 0.5, it is rounded down; if its decimal part is greater than or equal to 0.5, it is rounded up. That is, if f0 is calculated to be 12.25, the initial operating frequency is 12Hz; if f0 is calculated to be 12.5, the initial operating frequency is 13Hz.

[0067] fR is the conversion frequency corresponding to each heat level. Recommended values ​​are shown in Table 1.

[0068] fF is the conversion frequency corresponding to each wind speed; recommended values ​​are shown in Table 2.

[0069] T 外-max The highest outer ring temperature corresponding to the air conditioner's heating operation;

[0070] T 外环 This refers to the current outer ring temperature.

[0071] T 内-max This refers to the highest inner ring temperature corresponding to the air conditioner's heating operation.

[0072] T 内环 This is the current inner ring temperature;

[0073] A is the outer ring conversion factor, with a recommended value of 0.25;

[0074] B is the inner ring conversion factor, with a recommended value of 0.5;

[0075] C is the frequency correction value, and its calculation formula is: C = f min -fR -适中 -fF -弱 , where f min This refers to the minimum frequency at which the air conditioner operates in heating mode; fR -适中 The conversion frequency corresponding to moderate heat; fF -弱 This is the calculated frequency corresponding to the low wind setting.

[0079] windshield weak Weak Moderate Strong powerful fF 1 2 3 4 5

[0080] Step S2: Control the air conditioner to run for a first set time t1 according to the calculated initial operating frequency f0; that is, after the compressor is turned on in personalized heating and air supply mode, it first runs according to the calculated initial operating frequency f0; the indoor fan starts for a first set time t1, where the first set time t1 can be 20 minutes. That is, after the indoor fan starts for 20 minutes, it exits the initial operating frequency operation and switches to fuzzy control according to f = f0. 当前运行频率 +Δf is used for control; while fuzzy control includes the following steps:

[0081] Step S3: Obtain the temperature difference ΔT between the inner tube and the inner tube.

[0082] The temperature difference ΔT between the inner tube and the inner tube is calculated using the following formula:

[0083] Inner tube temperature difference ΔT=T 目标内管温 -T 当前内管温 Among them, T 目标内管温 The following formula is used to obtain it;

[0084] T 目标内管温 =T 内环 +T X-R +T X-F Among them, T X-R For thermal correction temperature, recommended values ​​are shown in Table 3; TX-F For the fan temperature correction, the recommended values ​​are shown in Table 4.

[0087] Table 4

[0088] windshield weak Weak Moderate Strong powerful <![CDATA[T X-F ]]> 0.5 1 1.5 2 2.5

[0089] Step S4: Compare the obtained inner tube temperature difference ΔT with the preset inner tube temperature difference range [T1, T2]. It should be noted that in this embodiment, the recommended value for T1 in the preset inner tube temperature difference range [T1, T2] is -0.5℃, and the recommended value for T2 is 0.5℃.

[0090] Step S5: Based on the comparison results, perform different fuzzy control steps on the compressor operating frequency f.

[0091] The air conditioner control method of the present invention determines the initial operating frequency of the compressor based on the inner ring, the user-set temperature and fan speed. After the operation is stable, the compressor operating frequency is fuzzy controlled by comparing the difference between the inner pipe temperature and the preset target inner pipe temperature. It does not require heating the entire open space. By operating the compressor at a low frequency, it delivers air that is slightly higher than the human skin temperature, which can satisfy human comfort and achieve energy-saving operation.

[0092] Specifically, in this invention, based on the comparison results, different fuzzy control steps are performed on the compressor operating frequency f, including:

[0093] When the temperature difference ΔT in the inner tube is within the preset temperature difference range [T1, T2] and is stably maintained for a second set time t2, or when the temperature difference ΔT in the inner tube undergoes several alternating positive and negative fuzzy inferences, the fuzzy control step for the stabilization period of the inner tube temperature is executed. It should be noted that the above judgment refers to judgment condition a, when the temperature difference ΔT in the inner tube is within the preset temperature difference range [T1, T2] and is stably maintained for a second set time t2; or judgment condition b, when the temperature difference ΔT in the inner tube is within the preset temperature difference range [T1, T2] and the temperature difference ΔT in the inner tube undergoes several alternating positive and negative fuzzy inferences, the fuzzy control step for the stabilization period of the inner tube temperature is executed when either of the two judgment conditions is met.

[0094] As a further improvement of the present invention, when calculating the stable maintenance time within the preset inner tube temperature difference ΔT ∈ [T1, T2], if the inner tube temperature difference ΔT exceeds the preset inner tube temperature difference range [T1, T2], the stable maintenance time is reset to zero and recalculated; or, when calculating the number of alternating changes in the positive and negative directions, if the inner tube temperature difference ΔT exceeds the preset inner tube temperature difference range [T1, T2], the number of alternating changes is reset to zero and recalculated, and multiple consecutive changes in the positive or negative directions are not accumulated.

[0095] Specifically, for example, when T1 is -0.5℃ and T2 is 0.5℃, that is, when:

[0096] a. When -0.5℃≤△T≤0.5℃, and after maintaining a stable temperature for the second set time t2min (recommended value for t2 is 20min), the fuzzy control step for the stabilization period of the inner tube temperature is executed. When △T deviates from the ±0.5℃ temperature range, the time is reset to zero and recounted. For example, if the target inner tube temperature is 20℃, and the current detected inner tube temperature is 20.5℃, then the count starts from now. If the inner tube temperature becomes 21℃ 10 minutes after the start of the count, it has deviated from the T1 (recommended value for T1 -0.5℃)≤△T≤T2 (recommended value for T2 0.5℃) temperature range, and the count is reset to 0. For example, if the inner tube temperature returns to 20.5℃ after 5 minutes, then the count starts again from 0 minutes, instead of from 10 minutes.

[0097] b. When -0.5℃≤△T≤0.5℃, after performing 4 alternating changes of △T in the positive and negative directions using fuzzy inference, the fuzzy control step for the stable period of the inner tube temperature is executed. Continuous changes in either the positive or negative direction are not accumulated; if △T deviates from the ±0.5℃ temperature band, the count is reset to zero and restarted. For example, if the current inner tube temperature is 20.5℃, it enters the T1≤△T≤T2 temperature band. If, after 2 minutes, the inner tube temperature becomes 19.6℃, which is also within the temperature band, the alternation count is recorded as 1. If, after 2 minutes, the inner tube temperature becomes 19.8℃, the alternation count remains 1. If, after 2 minutes, the inner tube temperature becomes 20.3℃, the alternation count is recorded as 2.

[0098] The two judgment conditions, a and b, are in a parallel judgment mode. As long as one of them is met, the system enters the stable period control. For example, if the target inner tube temperature is 20℃ and the current detected inner tube temperature is 20.5℃, then the system enters the temperature zone T1≤△T≤T2. If, after 2 minutes, the inner tube temperature becomes 19.6℃, which is also within the temperature zone, then this is recorded as the number of alternations 1. If, after 2 minutes, the inner tube temperature becomes 20.4℃, this is recorded as the number of alternations 2. If, after 2 minutes, the inner tube temperature becomes 19.7℃, this is recorded as the number of alternations 3. If, after 2 minutes, the inner tube temperature becomes 20.4℃, this is recorded as the number of alternations 4. Then condition b is satisfied.

[0099] If neither of the above judgment conditions a or b is met, then the fuzzy control step for the unstable period of the internal pipe temperature is executed.

[0100] In this embodiment, the fuzzy control step for the stabilization period of the inner tube temperature includes:

[0101] The time t required to obtain the temperature change T3 of the inner tube 变 The temperature change of the inner tube, T3, is within the preset temperature difference range of the inner tube [T1, T2].

[0102] Based on the required time t for acquisition 变 Determine the fuzzy control frequency value Δf;

[0103] Based on the determined fuzzy control frequency value Δf, the compressor control frequency f is obtained; where,

[0104] f = f 当前运行频率 +Δf;

[0105] The compressor is controlled to operate at a control frequency f.

[0106] Specifically, in this embodiment:

[0107] (1) If 0 ≤ ΔT ≤ T2, the time t required to obtain the temperature change T3℃ in the inner tube (the recommended value of |T3| is 0.3℃) 变 Temperature changes approaching the set temperature are marked as "+", and temperature changes far from the set temperature are marked as "-". "+" and "-" refer to the calculated temperature (t). 变 How are positive and negative defined? This corresponds to the following table (t). 变 The positive and negative values ​​of t, and different t 变 Positive and negative values ​​correspond to different upper and lower limits of Δf, depending on the required time t. 变 Determine the frequency value Δf for fuzzy control.

[0108] The fuzzy control frequency value Δf is obtained through interpolation. For example, when 0 ≤ ΔT ≤ T2, t is calculated. 变 The value is -2, which falls within the range specified in the rightmost column of Table 5. Therefore, Δf = (-2 - 0) * (4 - 2) / (-5 - 0). The table provides t. 变 Recommended upper limit (i.e., Δfmax) and lower limit (i.e., Δfmin) for Δf within the interval. t 变 The interval and the upper and lower limits of △f are shown in Table 5.

[0117] Based on the determined fuzzy control frequency value Δf, the compressor control frequency f is obtained; where,

[0118] f = f 当前运行频率 +Δf;

[0119] The compressor is controlled to operate at a control frequency f.

[0120] Specifically, in this embodiment:

[0121] (1) If T4 (recommended value of T4 is 8℃) ≤ △T, calculate the time t required for the inner tube temperature to change by T3℃ (recommended value of |T3| is 0.3℃). 变 According to the required time t 变 Determine the fuzzy control Δf, and give t 变 The upper limit (i.e., Δfmax) and lower limit (i.e., Δfmin) of Δf within the interval, where "-" indicates a decrease in frequency, and the rest are t 变 The corresponding Δf is obtained through interpolation. 变 The interval and the upper and lower limits of △f are shown in Table 7.
