This fluctuation leads to variations in the system's cooling or heating capacity, which in turn reduces user comfort and experience, especially in situations with significant temperature differences between indoor and outdoor environments.

[0038] According to an embodiment of the present invention, a method embodiment for regulating exhaust fluctuations in an air conditioner is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0039] Figure 2 This is a flowchart of an air conditioner exhaust fluctuation adjustment method according to an embodiment of the present invention, such as... Figure 2 As shown, the method for regulating exhaust fluctuations in this air conditioner includes the following steps:

[0040] Step S202: After each start-up of the air conditioner, if exhaust fluctuations are detected, exhaust fluctuation information of the air conditioner within a first predetermined time period is obtained. Exhaust fluctuations refer to the phenomenon that among multiple exhaust temperatures of the air conditioner within a predetermined running time after start-up, there is an exhaust temperature that exceeds the preset exhaust temperature range.

[0041] In this embodiment, the air conditioner will activate the exhaust fluctuation detection function after each startup to determine whether there is an exhaust abnormality, such as exhaust fluctuation.

[0042] For example, when the air conditioner receives a start command, under normal start-up conditions, it will trigger the exhaust fluctuation detection function to obtain the exhaust temperature of the air conditioner during this period of operation. It will then compare the exhaust temperatures observed during this period with a preset exhaust temperature range. If any of the multiple exhaust temperatures within this period exceeds the preset range, it is determined that the air conditioner has experienced its first exhaust fluctuation during this operation. At this point, the time of this first exhaust fluctuation is used as the starting point to collect exhaust fluctuation information over a subsequent period to determine whether the exhaust fluctuation has subsided, thus aiding the air conditioner in making a decision.

[0043] Step S204: When it is determined that the exhaust fluctuation adjustment function needs to be activated based on the exhaust fluctuation information, the current indoor ambient temperature, the current outdoor ambient temperature, and the current actual exhaust temperature of the air conditioner are obtained.

[0044] In this embodiment, after determining from the exhaust fluctuation information that the exhaust fluctuation has not recovered within the aforementioned subsequent time period, in order to shorten the duration of exhaust temperature fluctuation and thus improve user comfort and experience, the current indoor ambient temperature, the current outdoor ambient temperature, and the current actual exhaust temperature of the room where the air conditioner is located are collected, and the exhaust fluctuation adjustment method is determined based on these parameters.

[0045] Step S206: Determine the indoor-outdoor temperature difference between the current indoor ambient temperature and the current outdoor ambient temperature, and simultaneously determine the exhaust temperature difference between the current actual exhaust temperature and the target exhaust temperature.

[0046] In this embodiment, the indoor-outdoor temperature difference between the current indoor ambient temperature and the current outdoor ambient temperature, as well as the exhaust temperature difference between the current actual exhaust temperature and the target exhaust temperature, can be determined separately, so as to adjust the exhaust fluctuation based on the indoor-outdoor temperature difference and the exhaust temperature difference.

[0047] Step S208: Determine the target action that the air conditioner needs to perform under the exhaust fluctuation adjustment function based on the exhaust temperature difference, and determine the action parameters of the target action based on the indoor and outdoor temperature difference and the exhaust temperature difference.

[0048] In this embodiment, the action to be performed under the exhaust fluctuation regulation function can be determined first based on the exhaust temperature difference. For example, adjusting the opening of the air conditioner's electronic expansion valve or adjusting one or both of the air conditioner's fan speed. Determining the exhaust action based on the exhaust temperature difference can both regulate the air conditioner to a stable state and ensure that the exhaust temperature does not deteriorate due to the exhaust fluctuation regulation function.

[0049] Next, the action parameters of the target action can be determined based on the indoor and outdoor temperature difference and the exhaust temperature difference. For example, when the action to be performed is to adjust the opening of the electronic expansion valve, the adjustment rate of the opening; when the action to be performed is to adjust the speed of the air conditioner fan, the speed.

[0050] Step S210: Control the air conditioner to perform the target action according to the action parameters in order to adjust the exhaust fluctuation.

[0051] As can be seen from the above, in this embodiment of the invention, if exhaust fluctuations are detected after each start-up of the air conditioner, exhaust fluctuation information of the air conditioner within a first predetermined time period is obtained. Exhaust fluctuation refers to the phenomenon where, among multiple exhaust temperatures within a predetermined operating period after the air conditioner is started, an exhaust temperature exceeds a preset exhaust temperature range. When it is determined that the exhaust fluctuation adjustment function needs to be activated based on the exhaust fluctuation information, the current indoor ambient temperature, the current outdoor ambient temperature, and the current actual exhaust temperature of the air conditioner are obtained. The indoor-outdoor temperature difference between the current indoor ambient temperature and the current outdoor ambient temperature is determined, and the difference between the current actual exhaust temperature and the target exhaust temperature is also determined. Exhaust temperature difference; based on the exhaust temperature difference, determine the target action that the air conditioner needs to perform under the exhaust fluctuation regulation function, and determine the action parameters of the target action based on the indoor / outdoor temperature difference and the exhaust temperature difference; control the air conditioner to perform the target action according to the action parameters to regulate exhaust fluctuations. This achieves the purpose of determining the control method of electronic expansion valve opening adjustment rate and / or fan speed adjustment when exhaust fluctuations occur, based on indoor / outdoor ambient temperature, actual exhaust temperature, target exhaust temperature, and operating mode. This achieves the technical effect of shortening the duration of exhaust temperature fluctuations when exhaust fluctuations occur, thereby improving user comfort and experience.

[0052] Therefore, the technical solution provided by the embodiments of the present invention solves the technical problem in the related art that the exhaust temperature of the air conditioner fluctuates, which can easily cause fluctuations in the cooling or heating capacity of the air conditioner, and thus cause instability in the operation of the air conditioner.

[0053] According to the above embodiments of the present invention, determining the exhaust temperature difference between the current actual exhaust temperature and the target exhaust temperature includes: selecting the target exhaust temperature from an indoor / outdoor ambient temperature-exhaust temperature mapping table based on the current indoor ambient temperature and the current outdoor ambient temperature, wherein the indoor / outdoor ambient temperature-exhaust temperature mapping table is used to record the relationship between different outdoor ambient temperatures and indoor ambient temperatures and exhaust temperatures; obtaining the current actual exhaust temperature; and determining the exhaust temperature difference between the current actual exhaust temperature and the target exhaust temperature.

[0054] In this embodiment, the relationship between indoor and outdoor ambient temperature and exhaust temperature can be pre-established based on experimental data (e.g., different indoor and outdoor ambient temperatures, and the optimal exhaust temperature under different indoor and outdoor ambient temperatures) before the air conditioner leaves the factory. This relationship can be recorded in the form of a mapping table, or in other forms, without any specific limitation.

[0055] Next, the established indoor and outdoor ambient temperature-exhaust temperature mapping table is stored in the air conditioner's processing center so that it can be used directly when needed, which is convenient and improves the efficiency of obtaining the target exhaust temperature. This allows for the rapid determination of the exhaust temperature difference, and thus the rapid determination of the actions to be taken.

[0056] According to the above embodiments of the present invention, determining that the exhaust fluctuation adjustment function needs to be activated based on exhaust fluctuation information includes one of the following: when the exhaust fluctuation information indicates that the air conditioner still experiences a predetermined number of exhaust fluctuations within a first predetermined time period, it is determined that the exhaust fluctuation adjustment function needs to be activated; when the exhaust fluctuation information indicates that the air conditioner does not experience exhaust fluctuations within the first predetermined time period but experiences exhaust fluctuations within a second time period including the first predetermined time period, it is determined that the exhaust fluctuation adjustment function needs to be activated.

[0057] In this embodiment, the need to activate the exhaust fluctuation adjustment function can be determined in two ways. For example, if the exhaust fluctuation information indicates that the air conditioner experiences a predetermined number of exhaust fluctuations within a certain period after the first occurrence of an exhaust fluctuation, it is determined that the exhaust fluctuation adjustment function needs to be activated. Alternatively, if the exhaust fluctuation information indicates that the air conditioner does not experience exhaust fluctuations for a certain period after the first occurrence of an exhaust fluctuation, but exhaust fluctuations occur within a period including the period after the first occurrence of an exhaust fluctuation, then it is determined that the exhaust fluctuation adjustment function needs to be activated. Conversely, during air conditioner operation, if the exhaust temperature stabilizes within 60 seconds after the first occurrence of an exhaust fluctuation, and no further exhaust fluctuations are detected for 180 seconds, then the system is considered not to activate the exhaust fluctuation adjustment function in this situation.

[0058] Figure 3 This is a flowchart of an optional air conditioner exhaust fluctuation adjustment method according to an embodiment of the present invention, such as... Figure 3As shown, after the air conditioner detects exhaust fluctuations for the first time after each startup, the number of exhaust fluctuations can be counted to determine whether the exhaust fluctuation regulation function needs to be activated. For example, if the exhaust temperature remains fluctuating within 60 seconds after the first exhaust fluctuation after each startup, or if the exhaust temperature is stable within 60 seconds but more than one exhaust fluctuation occurs within a continuous 180-second monitoring period, then the exhaust fluctuation regulation function is activated. Otherwise, the system does not activate the exhaust fluctuation regulation function. Next, the current indoor ambient temperature, current outdoor ambient temperature, and actual exhaust temperature can be detected, and the target exhaust temperature can be obtained. Then, the absolute values ​​of the indoor-outdoor temperature difference and the exhaust temperature difference are determined. Then, based on the absolute value of the exhaust temperature difference, the action to be performed under the exhaust fluctuation regulation function is selected; and the parameters of the selected action are determined based on the absolute values ​​of the indoor-outdoor temperature difference and the exhaust temperature difference, thereby controlling the air conditioner to operate the selected action according to the determined action parameters to regulate exhaust fluctuations and shorten the duration of exhaust fluctuations.

[0059] It should be noted that multiple preset temperatures are used in the embodiments of this invention. These multiple preset temperatures can be determined based on the model, type, and operating conditions of the air conditioner. The following explanation uses a dual-cabinet air conditioner as an example, with the first preset temperature being 1℃, the second preset temperature being 4℃, the third preset temperature being 3℃, the fourth preset temperature being 2℃, and the fifth preset temperature being 8℃.

[0060] Regarding the selection of the target action, in an optional embodiment of the present invention, the target action to be performed by the air conditioner under the exhaust fluctuation regulation function is determined based on the exhaust temperature difference, including: when the exhaust temperature difference indicates that the temperature difference between the actual exhaust temperature and the target exhaust temperature is greater than a first preset temperature and not greater than a second preset temperature, the target action is determined to be adjusting the opening of the air conditioner's electronic expansion valve; when the exhaust temperature difference indicates that the temperature difference between the actual exhaust temperature and the target exhaust temperature is greater than the second preset temperature, the target action is determined to be: adjusting the opening of the air conditioner's electronic expansion valve and adjusting the speed of the air conditioner's fan.

[0061] In this embodiment, the current indoor and outdoor ambient temperatures can be detected first to calculate the target exhaust temperature value under the current environment. The target exhaust temperature value is then compared with the actual exhaust temperature value, and the difference is used to select the next action through the table below.

[0062] For example, when the absolute value of the temperature difference between the actual and target exhaust temperatures (represented by the exhaust temperature difference) is greater than 1°C but not greater than 4°C, the target action is determined to be adjusting the opening of the air conditioner's electronic expansion valve. When the absolute value of the temperature difference between the actual and target exhaust temperatures is greater than 4°C, the target action is determined to be adjusting the opening of the air conditioner's electronic expansion valve and simultaneously adjusting the speed of the air conditioner's fan. Furthermore, when the absolute value of the temperature difference between the actual and target exhaust temperatures is not greater than 1°C, no action is required.

[0063] This can be represented by Table 1 below, which records the correspondence between the absolute value of the temperature difference between the actual exhaust temperature and the target exhaust temperature and the executed action.

[0066] By implementing the above restrictions, the exhaust temperature can be quickly adjusted to a stable state, while also ensuring that the exhaust temperature will not deteriorate due to the exhaust fluctuation adjustment function, which would otherwise cause the temperature to become stable.

[0067] Regarding the adjustment of the opening degree, in an optional embodiment of the present invention, when the target action is to adjust the opening degree of the electronic expansion valve of the air conditioner, if the indoor and outdoor temperature difference is not greater than a third preset temperature, the action parameters of the target action are determined based on the indoor and outdoor temperature difference and the exhaust temperature difference, including: when the exhaust temperature difference is greater than a first preset temperature but not greater than a fourth preset temperature, the opening degree adjustment rate of the electronic expansion valve is determined to be 1 step / 360s; when the exhaust temperature difference is greater than a fourth preset temperature but not greater than a second preset temperature, the opening degree adjustment rate of the electronic expansion valve is determined to be 1 step / 240s; when the exhaust temperature difference is greater than a second preset temperature, the opening degree adjustment rate of the electronic expansion valve is determined to be 1 step / 120s.

[0068] When the target action is to adjust the valve opening, the system detects the current indoor ambient temperature Tinner, the outdoor ambient temperature Touter, the actual exhaust temperature T1, and the target exhaust temperature T2, and calculates the absolute values ​​Ta and Tb of (Tinner - Touter) and (T1 - T2), respectively. The system then selects the opening adjustment rate of the electronic expansion valve according to Table 2. Table 2 shows the correspondence between the absolute values ​​Ta (Tinner - Touter), Tb (T1 - T2), and the opening adjustment rate.

[0072] This embodiment mainly focuses on the case where the absolute value Ta of T_inner - T_outer in Table 2 satisfies |T_inner - T_outer| ≤ 3℃. See Table 2 for details, which will not be repeated here.

[0073] Regarding the adjustment of the opening degree, in an optional embodiment of the present invention, when the target action is to adjust the opening degree of the electronic expansion valve of the air conditioner, if the indoor and outdoor temperature difference is greater than a third preset temperature but not greater than a fifth preset temperature, the action parameters of the target action are determined based on the indoor and outdoor temperature difference and the exhaust temperature difference, including: when the exhaust temperature difference is greater than a first preset temperature but not greater than a fourth preset temperature, the opening degree adjustment rate of the electronic expansion valve is determined to be 1 step / 330s; when the exhaust temperature difference is greater than a fourth preset temperature but not greater than a second preset temperature, the opening degree adjustment rate of the electronic expansion valve is determined to be 1 step / 200s; when the exhaust temperature difference is greater than a second preset temperature, the opening degree adjustment rate of the electronic expansion valve is determined to be 1 step / 80s.

[0074] This embodiment mainly focuses on the case where the absolute value Ta of T_inner - T_outer in Table 2 satisfies 3℃ < |T_inner - T_outer| ≤ 8℃. See Table 2 for details, which will not be repeated here.

[0075] Regarding the adjustment of the opening degree, in an optional embodiment of the present invention, when the target action includes adjusting the opening degree of the electronic expansion valve of the air conditioner, if the indoor and outdoor temperature difference is greater than a fifth preset temperature, the action parameters of the target action are determined based on the indoor and outdoor temperature difference and the exhaust temperature difference, including: when the exhaust temperature difference is greater than a first preset temperature but not greater than a fourth preset temperature, the opening degree adjustment rate of the electronic expansion valve is determined to be 1 step / 30s; when the exhaust temperature difference is greater than a fourth preset temperature but not greater than a second preset temperature, the opening degree adjustment rate of the electronic expansion valve is determined to be 1 step / 160s; when the exhaust temperature difference is greater than a second preset temperature, the opening degree adjustment rate of the electronic expansion valve is determined to be 1 step / 40s.

[0076] This embodiment mainly focuses on the case where the absolute value Ta of T_inner - T_outer in Table 2 satisfies 8℃ < |T_inner - T_outer|. See Table 2 for details, which will not be repeated here.

[0077] The adjustment rate is determined by the temperature difference between the inner and outer loops. This approach considers both the overall reliability of the system and the impact of ambient temperature fluctuations on comfort during exhaust gas temperature regulation. (For example, during cooling, when the indoor / outdoor temperature difference is small, a slower adjustment rate of the electronic expansion valve results in minimal fluctuations in the system's outlet air temperature, and users will not perceive noticeable changes in the outlet air temperature. When the difference is large, a faster adjustment rate of the electronic expansion valve is needed to ensure that the exhaust temperature stabilizes quickly, thus reducing the duration of user discomfort.)

[0078] The following explains how to adjust the fan speed.

[0079] In an optional embodiment of the present invention, when the target action includes adjusting the speed of the air conditioner's fan, if the air conditioner is in cooling mode, the action parameters of the target action are determined based on the indoor-outdoor temperature difference and the exhaust temperature difference, including: when the indoor-outdoor temperature difference is not greater than a fifth preset ambient temperature, the action parameters are determined as follows: the speed of the air conditioner's upper fan is the original speed, and the speed of the air conditioner's lower fan is the sum of the original speed and a first speed compensation value; when the indoor-outdoor temperature difference is greater than the fifth preset ambient temperature, the action parameters are determined as follows: the speed of the air conditioner's upper fan is the sum of the original speed and a second speed compensation value, and the speed of the air conditioner's lower fan is the sum of the original speed and a third speed compensation value.

[0080] In this embodiment, when the air conditioner is in cooling mode, the speed of the upper and lower fans of the air conditioner can be determined based on the temperature difference between indoors and outdoors and the temperature difference between exhaust gas and outdoor air.

[0081] In other words, when the action performed is to adjust the fan speed, the air conditioner calculates the absolute value Ta of Tin - Toutai based on the current indoor ambient temperature Tin, the outdoor ambient temperature Toutai, and the current operating mode. The actual operating speeds of the upper and lower fans are then determined according to Table 3 below:

[0082] Table 3

[0083]

[0084]

[0085] As shown in Table 3, in cooling mode, if the indoor-outdoor temperature difference and the exhaust temperature difference (absolute value Ta of T_indoor - T_outdoor) satisfy |T_indoor - T_outdoor| ≤ 8℃, the speed of the upper fan can be the original speed, and the speed of the lower fan can be increased by 20 rpm based on the original speed; if the indoor-outdoor temperature difference and the exhaust temperature difference (absolute value Ta of T_indoor - T_outdoor) satisfy 8℃ < |T_indoor - T_outdoor|, the speed of the upper fan can be increased by 10 rpm based on the original speed, and the speed of the lower fan can be increased by 40 rpm based on the original speed.

[0086] In an optional embodiment of the present invention, when the target action includes adjusting the speed of the air conditioner's fan, if the air conditioner is in heating mode, the action parameters of the target action are determined based on the indoor-outdoor temperature difference and the exhaust temperature difference, including: when the indoor-outdoor temperature difference is not greater than the sixth preset ambient temperature, the action parameters are determined as follows: the speed of the air conditioner's upper fan is the sum of the original speed and the fourth speed compensation value, and the speed of the air conditioner's lower fan is the original speed; when the indoor-outdoor temperature difference is greater than the sixth preset ambient temperature, the action parameters are determined as follows: the speed of the air conditioner's upper fan is the sum of the original speed and the fifth speed compensation value, and the speed of the air conditioner's lower fan is the sum of the original speed and the sixth speed compensation value.

[0087] This embodiment describes the situation where the air conditioner is in heating mode. As shown in Table 3 above, in heating mode, if the indoor-outdoor temperature difference and the exhaust temperature difference (absolute value Ta of T_indoor - T_outdoor) satisfy |T_indoor - T_outdoor| ≤ 13℃, the speed of the upper fan can be increased by 30 rpm based on the original speed, and the speed of the lower fan can be the original speed; if the indoor-outdoor temperature difference and the exhaust temperature difference (absolute value Ta of T_indoor - T_outdoor) satisfy 13℃ < |T_indoor - T_outdoor|, the speed of the upper fan can be increased by 60 rpm based on the original speed, and the speed of the lower fan can be increased by 20 rpm based on the original speed.

[0088] As can be seen from the above, this embodiment of the invention provides an adjustment method for dual-fan air conditioners after exhaust fluctuations occur, shortening the time of system instability caused by exhaust fluctuations and improving user comfort and experience. It enables dual-fan air conditioners to shorten the time of exhaust temperature fluctuations when exhaust fluctuations occur in cooling / heating operation modes, thereby improving user comfort and experience.

Furthermore, those skilled in the art should also understand that the embodiments described in the specification are preferred embodiments, and the actions and modules involved are not necessarily essential to this application.

[0090] Through the above description of the embodiments, those skilled in the art can clearly understand that the methods according to the above embodiments can be implemented by means of software plus necessary general-purpose hardware platforms. Of course, they can also be implemented by hardware, but in many cases the former is a better implementation method. Based on this understanding, the technical solution of this application, in essence, or the part that contributes to the prior art, can be embodied in the form of a software product. This computer software product is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk) and includes several instructions to cause a terminal device (which may be a mobile phone, computer, server, or network device, etc.) to execute the methods described in the various embodiments of this application.

[0091] According to embodiments of the present invention, an exhaust fluctuation regulating device for an air conditioner for implementing the above-described air conditioner exhaust fluctuation regulating method is also provided. Figure 4 This is a schematic diagram of an air conditioner exhaust fluctuation regulation device according to an embodiment of the present invention, such as... Figure 4 As shown, the device includes: a first acquisition unit 41, a second acquisition unit 43, a first determination unit 45, a second determination unit 47, and a control unit 49. The exhaust fluctuation adjustment device for this air conditioner will be described below.

[0092] The first acquisition unit 41 is used to acquire exhaust fluctuation information of the air conditioner within a first predetermined time period after the air conditioner is turned on and running each time. The exhaust fluctuation is the phenomenon that there is an exhaust temperature exceeding the preset exhaust temperature range among multiple exhaust temperatures within the predetermined running time after the air conditioner is turned on and running.

[0093] The second acquisition unit 43 is used to acquire the current indoor ambient temperature, the current outdoor ambient temperature and the current actual exhaust temperature of the air conditioner when it is determined that the exhaust fluctuation adjustment function needs to be activated based on the exhaust fluctuation information.

[0094] The first determining unit 45 is used to determine the indoor-outdoor temperature difference between the current indoor ambient temperature and the current outdoor ambient temperature, and at the same time determine the exhaust temperature difference between the current actual exhaust temperature and the target exhaust temperature.

[0095] The second determining unit 47 is used to determine the target action that the air conditioner needs to perform under the exhaust fluctuation adjustment function based on the exhaust temperature difference, and to determine the action parameters of the target action based on the indoor and outdoor temperature difference and the exhaust temperature difference.

[0096] Control unit 49 is used to control the air conditioner to perform target actions according to the action parameters in order to regulate exhaust fluctuations.

[0097] It should be noted that the first acquisition unit 41, the second acquisition unit 43, the first determination unit 45, the second determination unit 47, and the control unit 49 mentioned above correspond to steps S102 to S110 in the above embodiments. The five units and the corresponding steps implement the same instances and application scenarios, but are not limited to the content disclosed in the above embodiments.

[0098] As can be seen from the above, in the solution described in the above embodiments of the present invention, the first acquisition unit can acquire exhaust fluctuation information of the air conditioner within a first predetermined time period after each start-up of the air conditioner if exhaust fluctuation is detected. Exhaust fluctuation refers to the phenomenon that one of the multiple exhaust temperatures exceeds a preset exhaust temperature range within a predetermined operating time after the air conditioner is started up. Then, when the second acquisition unit determines that the exhaust fluctuation adjustment function needs to be activated based on the exhaust fluctuation information, it acquires the current indoor ambient temperature, the current outdoor ambient temperature, and the current actual exhaust temperature of the air conditioner. Next, the first determination unit determines the indoor-outdoor temperature difference between the current indoor ambient temperature and the current outdoor ambient temperature, and simultaneously determines the current actual exhaust temperature. The system calculates the exhaust temperature difference between the indoor and outdoor temperatures and the target exhaust temperature. A second determining unit then determines the target action the air conditioner needs to perform under the exhaust fluctuation regulation function based on this temperature difference. The system also determines the action parameters for the target action based on the indoor / outdoor temperature difference and the exhaust temperature difference. Finally, the control unit controls the air conditioner to execute the target action according to these parameters to regulate exhaust fluctuations. This achieves the goal of determining the control method for adjusting the opening rate of the electronic expansion valve and / or the fan speed based on the indoor / outdoor ambient temperature, actual exhaust temperature, target exhaust temperature, and operating mode when exhaust fluctuations occur. This results in a shorter duration of exhaust temperature fluctuations, thereby improving user comfort and experience.
