At the same time, the installation environment of the outdoor unit of air conditioners in modern building structures (such as commercial housing) is increasingly limited, and there are generally situations such as small installation space and blocked ventilation (such as the air outlet being blocked by louvers). In such a complex and severe situation, users have put forward higher requirements for the cooling capacity of air conditioners in extremely high-temperature environments. However, traditional air conditioners are restricted by the heat dissipation design, with poor heat dissipation effect, resulting in a decline in the cooling capacity, which affects the user's cooling comfort experience.

[0029] In order to enable those of ordinary skill in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0030] It should be noted that the terms "first", "second", etc. in the description, claims, and above-mentioned drawings of the present disclosure are used to distinguish similar objects and do not necessarily describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0031] The air conditioner and its control method, control device, electronic device, and storage medium according to the embodiments of the present disclosure will be described below with reference to the drawings.

[0032] Figure 1 It is a flowchart of an air conditioner control method according to an embodiment of the present disclosure.

[0033] It should be noted that the air conditioner control method of the embodiments of the present disclosure can be applied to an air conditioner control device. In some possible embodiments, the air conditioner control device can be configured in an electronic device so that the electronic device can execute the air conditioner control function.

[0034] As Figure 1 shown, the air conditioner control method of the embodiments of the present disclosure includes:

[0035] S101, in response to the air conditioner operating in the cooling mode, obtain the outdoor ambient temperature and the compressor operating current.

[0036] If the air conditioner receives a cooling mode operation instruction, it means that the user has selected the cooling mode in some way (such as a remote control, a control panel, etc.). The present disclosure uses multiple methods to confirm whether the air conditioner is actually in the cooling mode currently. The following specific examples illustrate these determination methods:

[0037] Example 1: A method for determining the cooling mode of an air conditioner based on the operation mode identification bit.

[0038] There is a pre-set operation mode identification bit inside the air conditioner, which is used to indicate the working mode that the air conditioner is currently in. The working mode includes but is not limited to the cooling mode, the heating mode, and the air supply mode. When the air conditioner needs to confirm whether it is in the cooling mode, it can check whether the operation mode identification bit is set to a state representing the cooling mode. If the state matches, according to the pre-set determination rule, it is confirmed that the air conditioner is operating in the cooling mode.

[0039] Example 2: A method for determining the cooling mode of an air conditioner based on the four-way valve state detection.

[0040] The four-way valve is a component in the air conditioner that controls the circulation direction of the refrigerant. By detecting the state of the four-way valve, the circulation direction of the refrigerant within the air conditioner can be determined. If the detection result shows that the refrigerant circulation direction corresponding to the state of the four-way valve is the refrigeration direction, then based on the working principle of the air conditioner and the preset determination logic, it is confirmed that the air conditioner is operating in the refrigeration mode.

[0041] Example 3: A method for determining the refrigeration mode of an air conditioner based on user operation records.

[0042] When the user operates through the remote control or control panel of the air conditioner to select the refrigeration mode option, the air conditioner will respond immediately and record this operation instruction. The recorded information of this operation instruction can serve as a key basis for subsequent verification or confirmation of the air conditioner's operating mode. When the air conditioner needs to confirm whether it is in the refrigeration mode, it can check whether this recorded information exists. If the information exists and meets the preset conditions, then based on the preset determination rules, it is confirmed that the air conditioner is operating in the refrigeration mode.

[0043] During the operation of the air conditioner in the refrigeration mode, the system will perform parameter acquisition operations: the outdoor ambient temperature T 室外环境 is collected in real time through a temperature sensor installed on the outdoor unit of the air conditioner; the running current I of the compressor is collected in real time through a current sensor installed in the power supply circuit of the compressor to ensure the accuracy and real-time nature of the data.

[0044] S102, when the outdoor ambient temperature is greater than or equal to the set temperature threshold, control the operating state of the air conditioner according to the temperature change rate of the outdoor ambient temperature and the current change rate of the compressor running current.

[0045] After collecting the outdoor ambient temperature T 室外环境 , judge the outdoor ambient temperature T 室外环境 . If the outdoor ambient temperature T 室外环境 is greater than or equal to the set temperature threshold (such as 35 °C), then detect through the temperature change rate ΔT 高温制冷变化 of the outdoor ambient temperature per unit cycle within the Δt time period continuously, and simultaneously detect the current change rate ΔI 高温制冷变化 of the compressor running current per unit cycle, and control the operating state of the air conditioner according to the temperature change rate ΔT 高温制冷变化 of the outdoor ambient temperature and the current change rate ΔI 高温制冷变化 of the compressor running current.

[0046] The following uses specific examples to illustrate the process of controlling the operating state of the air conditioner according to the temperature change rate ΔT 高温制冷变化 of the outdoor ambient temperature and the current change rate ΔI 高温制冷变化 of the compressor running current.

[0047] Example 1:

[0048] If the change rate ΔT of the outdoor ambient temperature 高温制冷变化 is greater than the preset temperature change rate threshold, and the change rate ΔI of the compressor operating current 高温制冷变化 is greater than the preset current change rate threshold, then control the air conditioner to enter the high-temperature refrigeration operation state. Among them, the preset temperature change rate threshold and the preset current change rate threshold can be set according to actual needs.

[0049] Example 2:

[0050] If the change rate ΔT of the outdoor ambient temperature 高温制冷变化 is greater than the target temperature change rate threshold and the change rate ΔI of the compressor operating current 高温制冷变化 is greater than the target current change rate threshold, then control the air conditioner to enter the high-temperature refrigeration operation state. Among them, the target temperature change rate threshold and the target current change rate threshold, that is, the control parameter thresholds, can be determined in the following way: Compare the outdoor ambient temperature with multiple preset outdoor ambient temperature intervals to determine the target outdoor ambient temperature interval to which the outdoor ambient temperature belongs, and based on the corresponding relationship between the outdoor ambient temperature interval and the temperature change rate threshold and the current change rate threshold, determine the target temperature change rate threshold and the target current change rate threshold that match the target outdoor ambient temperature interval.

[0051] Illustrate with examples:

[0052] The corresponding relationship between the outdoor ambient temperature interval and the temperature change rate threshold and the current change rate threshold can be set according to experimental data or by the user according to actual needs. The specific corresponding relationship is determined according to actual needs. For example, the corresponding relationship between the outdoor ambient temperature interval and the temperature change rate threshold and the current change rate threshold is shown in Table 1 below.

[0053] Table 1

[0054]

[0055] Among them, ΔT 高温制冷变化3 is not lower than ΔT 高温制冷变化2 , ΔT 高温制冷变化2 is not lower than ΔT 高温制冷变化1 ; ΔI 高温制冷变化3 is not lower than ΔI 高温制冷变化2 , ΔI 高温制冷变化2 is not lower than ΔI 高温制冷变化1 . That is to say, as the value of the outdoor ambient temperature interval increases, the temperature change rate threshold and the current change rate threshold increase accordingly.

[0056] As shown in Table 1, when 35 ≤ T 室外环境 <38 °C, that is, the outdoor ambient temperature T 室外环境The target outdoor ambient temperature range is [35, 38), and the target temperature change rate threshold matching the target outdoor ambient temperature range [35, 38) is ΔT 高温制冷变化1 and the target current change threshold is ΔI 高温制冷变化1 , if ΔT 高温制冷变化 > ΔT 高温制冷变化1 and ΔI 高温制冷变化 > ΔI 高温制冷变化1 , then control the air conditioner to enter the high-temperature refrigeration operation state.

[0057] When 38 ≤ T 室外环境 < 42°C, that is, the target outdoor ambient temperature range to which the outdoor ambient temperature T 室外环境 belongs is [38, 42), and the target temperature change rate threshold matching the target outdoor ambient temperature range [38, 42) is ΔT 高温制冷变化2 and the target current change threshold is ΔI 高温制冷变化2 , if ΔT 高温制冷变化 > ΔT 高温制冷变化2 and ΔI 高温制冷变化 > ΔI 高温制冷变化2 , then control the air conditioner to enter the high-temperature refrigeration operation state.

[0058] When T 室外环境 ≥ 42°C, that is, the target outdoor ambient temperature range to which the outdoor ambient temperature T 室外环境 belongs is [42, +∞), and the target temperature change rate threshold matching the target outdoor ambient temperature range [42, +∞) is ΔT 高温制冷变化3 and the target current change threshold is ΔI 高温制冷变化3 , if ΔT 高温制冷变化 > ΔT 高温制冷变化3 and ΔI 高温制冷变化 > ΔI 高温制冷变化3 , then control the air conditioner to enter the high-temperature refrigeration operation state.

[0059] To enable those skilled in the art to more clearly understand the process of the present disclosure for controlling the air conditioner to enter the high-temperature refrigeration operation state, as Figure 2 shown, the process of the present disclosure's embodiment for controlling the air conditioner to enter the high-temperature refrigeration operation state includes:

[0060] S201, the air conditioner receives a refrigeration mode operation instruction.

[0061] S202, during the operation of the air conditioner in the refrigeration mode, the outdoor ambient temperature T 室外环境 and the compressor running current are detected in real time.

[0062] S203, calculate the change rate ΔT 高温制冷变化 of the outdoor ambient temperature and the change rate ΔI 高温制冷变化 of the compressor running current within a unit cycle.

[0063] S204, Determine T 室外环境 whether it is greater than or equal to the set temperature threshold (such as 35°C). If so, execute step S205; if not, maintain the status quo.

[0064] S205, Determine ΔT 高温制冷变化 and ΔI 高温制冷变化 whether they are greater than the target temperature change rate threshold and the target current change rate threshold matching the target outdoor ambient temperature range to which the outdoor ambient temperature belongs. If so, execute step S206; if not, maintain the status quo.

[0065] S206, Control the air conditioner to enter the high-temperature refrigeration operation state.

[0066] Thus, during the operation of the air conditioner of the present disclosure in the refrigeration mode, the change rate of the outdoor ambient temperature and the change rate of the compressor operating current are used as the entry conditions for determining the high-temperature refrigeration operation state, which can more accurately control the switching of the air conditioner operation state, prevent the air conditioner from entering the high-temperature refrigeration operation state prematurely, and further enable the air conditioner to operate more efficiently in a high-temperature environment, improve the refrigeration capacity of the air conditioner, and enhance the user's refrigeration comfort experience. In addition, the present disclosure further optimizes the judgment logic. By accurately determining the target outdoor ambient temperature range to which the outdoor ambient temperature belongs and specifically determining the target temperature change rate threshold and the target current change rate threshold matching the target outdoor ambient temperature range, on this basis, when it is monitored that the change rate of the outdoor ambient temperature is greater than the target temperature change rate threshold and the change rate of the compressor operating current is greater than the target current change rate threshold, the air conditioner will automatically enter the high-temperature refrigeration operation state, further improving the accuracy of the air conditioner entering the high-temperature refrigeration operation state and ensuring the stable and efficient operation of the air conditioner in different high-temperature environments.

[0067] Figure 3 It is a flowchart of the current control method of the air conditioner in the high-temperature refrigeration operation state according to an embodiment of the present disclosure.

[0068] As Figure 3 shown, the current control method of the air conditioner in the high-temperature refrigeration operation state according to the embodiment of the present disclosure includes:

[0069] S301, In the high-temperature refrigeration operation state, compare the change rate of the outdoor ambient temperature with a plurality of preset temperature change rate intervals to determine the target temperature change rate interval to which the change rate of the outdoor ambient temperature belongs.

[0070] For example, the plurality of preset temperature change rate intervals include: [ΔT 高温制冷变化1 , ΔT 高温制冷变化2 ), [ΔT 高温制冷变化2 , ΔT高温制冷变化3 )、[ΔT 高温制冷变化3 , +∞). Compare ΔT 高温制冷变化 with [ΔT 高温制冷变化1 , ΔT 高温制冷变化2 ), [ΔT 高温制冷变化2 , ΔT 高温制冷变化3 ), [ΔT 高温制冷变化3 , +∞) to determine the target temperature change rate interval to which ΔT 高温制冷变化 belongs.

[0071] S302. Based on the correspondence between the temperature change rate interval and the compressor current threshold, determine the target current threshold of the compressor that matches the target temperature change rate interval.

[0072] S303. Adjust the current parameter of the compressor to the target current threshold.

[0073] Among them, the current parameter of the compressor includes at least one of the following:

[0074] The current value in the frequency slow rise stage, called I 制冷过流缓慢升频电流 ;

[0075] The current value in the frequency limit operation stage, called I 制冷过流限频 ;

[0076] The current value in the frequency reduction adjustment stage, called I 制冷过流降频 .

[0077] Among them, the preset correspondence between the temperature change rate interval and the compressor current threshold can be set according to experimental data or by the user according to actual needs. The specific correspondence is determined according to actual needs. For example, the preset correspondence between the temperature change rate interval and the compressor current threshold is shown in Table 2 below:

[0078] Table 2

[0079]

[0080] Among them, I 制冷过流缓慢升频电流1 is generally lower than I 制冷过流缓慢升频电流2 , I 制冷过流缓慢升频电流2 is generally lower than I 制冷过流缓慢升频电流3 ; I 制冷过流限频1 is generally lower than I 制冷过流限频2 , I 制冷过流限频2 is generally lower than I 制冷过流限频3 ; I 制冷过流降频1 is generally lower than I 制冷过流降频2 , I 制冷过流降频2 is generally lower than I 制冷过流降频3 . That is to say, as the value of the temperature change rate interval increases, the compressor current threshold increases accordingly.

[0081] As shown in Table 2, when ΔT 高温制冷变化1 ≤ΔT 高温制冷变化 <ΔT 高温制冷变化2 , that is, the target temperature change rate range to which ΔT 高温制冷变化 belongs is [ΔT 高温制冷变化1 , ΔT 高温制冷变化2 ), and the corresponding target I 高温制冷变化1 for [ΔT 高温制冷变化2 is I 制冷过流缓慢升频电流 = I 制冷过流缓慢升频电流1 , the target I 制冷过流限频 = I 制冷过流限频1 , the target I 制冷过流降频 = I 制冷过流降频1 , the target I 制冷过流停机 = I 制冷过流停机 (i.e., unchanged), and I 制冷过流缓慢升频电流 is adjusted to I 制冷过流缓慢升频电流1 , I 制冷过流限频 is adjusted to I 制冷过流限频1 , I 制冷过流降频 is adjusted to I 制冷过流降频1 , I 制冷过流停机 remains unchanged.

[0082] When ΔT 高温制冷变化2 ≤ΔT 高温制冷变化 <ΔT 高温制冷变化3 , that is, the target temperature change rate range to which ΔT 高温制冷变化 belongs is [ΔT 高温制冷变化2 , ΔT 高温制冷变化3 ), and the corresponding target I 高温制冷变化2 for [ΔT 高温制冷变化3 is I 制冷过流缓慢升频电流 = I 制冷过流缓慢升频电流2 , the target I 制冷过流限频 = I 制冷过流限频2 , the target I 制冷过流降频 = I 制冷过流降频2 , the target I 制冷过流停机 = I 制冷过流停机 (i.e., unchanged), and I 制冷过流缓慢升频电流 is adjusted to I 制冷过流缓慢升频电流2 , I 制冷过流限频 is adjusted to I 制冷过流限频2 , I 制冷过流降频 is adjusted to I 制冷过流降频2 , I 制冷过流停机 remains unchanged.

[0083] When ΔT 高温制冷变化 ≥ΔT 高温制冷变化3 , that is, the target temperature change rate range to which ΔT 高温制冷变化 belongs is [ΔT 高温制冷变化3 , +∞), and the corresponding target I 高温制冷变化3 for [ΔT 制冷过流缓慢升频电流 is I 制冷过流缓慢升频电流3, Target I 制冷过流限频 is I 制冷过流限频3 , Target I 制冷过流降频 is I 制冷过流降频3 , Target I 制冷过流停机 is I 制冷过流停机 (i.e., unchanged), and adjust I 制冷过流缓慢升频电流 to I 制冷过流缓慢升频电流3 , Adjust I 制冷过流限频 to I 制冷过流限频3 , I 制冷过流降频 adjust to I 制冷过流降频3 , I 制冷过流停机 remain unchanged.

[0084] To enable those skilled in the art to more clearly understand the process of the current control method of the air conditioner of the present disclosure in the high-temperature refrigeration operation state, as Figure 4 shown, the current control method of the air conditioner of the embodiment of the present disclosure in the high-temperature refrigeration operation state includes:

[0095] Figure 5 The present invention is a flowchart of a method for controlling an upper limit value of operating frequency and a frequency increase rate of an air conditioner in a high-temperature cooling operating state according to an embodiment of the present disclosure.

[0096] like Figure 5 As shown, the method for controlling the upper limit of the operating frequency of the air conditioner in the high-temperature cooling operating state according to the embodiment of the present disclosure includes:

[0097] S501, based on the correspondence between the temperature change rate interval and the outdoor ambient temperature change correction coefficient, determine the target outdoor ambient temperature change correction coefficient that matches the target temperature change rate interval; wherein the target temperature change rate interval is determined by comparing the change rate of the outdoor ambient temperature with a plurality of preset temperature change rate intervals.

[0098] S502: According to the target outdoor ambient temperature change correction coefficient, the upper limit value and the frequency increase rate of the compressor operation frequency are respectively corrected.

[0099] Among them, the corresponding relationship between the temperature change rate interval and the outdoor ambient temperature change correction coefficient can be set according to experimental data or the user according to actual needs. The specific corresponding relationship is determined according to actual needs. For example, the corresponding relationship between the temperature change rate interval and the outdoor ambient temperature change correction coefficient is shown in Table 3 and Table 4 below.

That is to say, as the value of the temperature change rate interval increases, the outdoor environmental temperature change correction coefficient increases accordingly.

[0106] As shown in Table 3 and Table 4, when ΔT 高温制冷变化1 ≤ΔT 高温制冷变化 <ΔT 高温制冷变化2 , that is, the target temperature change rate interval to which ΔT 高温制冷变化 belongs is [ΔT 高温制冷变化1 , ΔT 高温制冷变化2 ), and the target compensation coefficient corresponding to [ΔT 高温制冷变化1 , ΔT 高温制冷变化2 is K 室外环境温度变化修正系数1 , the upper limit value of the operating frequency of the compressor obtained is F 高温制冷运行频率上限 , and the frequency increase rate is F 高温制冷升频速率 .

Using ΔR 高温制冷(转速)补偿2 to compensate R 高温制冷(转速) , the rotational speed of the outdoor fan R 高温制冷(转速)2 after compensation is R 高温制冷(转速) +ΔR 高温制冷(转速)补偿2 .

[0120] When ΔT 高温制冷变化 ≥ΔT 高温制冷变化3 , that is, the target temperature change rate interval to which ΔT 高温制冷变化 belongs is [ΔT 高温制冷变化3 , +∞), and the target rotational speed compensation value corresponding to [ΔT 高温制冷变化3 , +∞) is ΔR 高温制冷(转速)补偿3 . The rotational speed of the outdoor fan obtained is R 高温制冷(转速) . Using ΔR 高温制冷(转速)补偿3 to compensate R 高温制冷(转速) , the rotational speed of the outdoor fan R 高温制冷(转速)3 after compensation is R高温制冷(转速) +ΔR 高温制冷(转速)补偿3 。
