Technical Field

[0001] This invention relates to the field of home appliance control technology, and more specifically, to a control method and device for an air conditioner, and an air conditioner. Background Technology

[0002] During the hot summer months, some areas experience extremely high temperatures, leading to higher cooling demands, longer air conditioning operation times, and heavier workloads. However, the installation environments of outdoor air conditioning units vary. Some units are installed in confined spaces with relatively enclosed environments, resulting in poor heat dissipation. In extreme heat, the operating environment of the outdoor unit becomes even more challenging, potentially approaching or exceeding the normal operating temperature range. This can cause poor reliability, low cooling capacity, or even shutdown of the air conditioner.

[0003] Regarding the aforementioned technologies, in high-temperature operating conditions, the outdoor unit of an air conditioner is easily affected by the installation space. In cases where the installation space for the outdoor unit is small and the environment is relatively enclosed, heat dissipation is poor, which leads to poor cooling performance of the air conditioner. Currently, no effective solution has been proposed. Summary of the Invention

[0043] As described in the background section, in related technologies, under high-temperature operating conditions, the outdoor unit of an air conditioner is easily affected by the installation space.

[0047] According to an embodiment of the present invention, a method embodiment for controlling 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.

[0048] Figure 2 This is a flowchart of an air conditioner control method according to an embodiment of the present invention, such as... Figure 2 As shown, the method includes the following steps:

[0049] Step S202, Acquisition Step: While the air conditioner compressor is running at the current operating frequency and the air conditioner's indoor fan is running at the current speed, acquire the current exhaust temperature of the air conditioner and the current coil temperature of the air conditioner's outdoor heat exchanger.

[0050] In this embodiment, during the operation of the air conditioner, the current exhaust temperature of the air conditioner and the current coil temperature of its outdoor heat exchanger can be obtained for subsequent adjustment of the air conditioner's operating parameters, so that the air conditioner can adapt to high-temperature conditions and operate reliably under high-temperature conditions.

[0051] Step S204, Determine the following steps: Determine the exhaust temperature difference between the current exhaust temperature and the target exhaust temperature, and determine the coil temperature difference between the current coil temperature and the target coil temperature.

[0052] In this embodiment, the target exhaust temperature and the target coil temperature can be obtained, and the current exhaust temperature can be compared with the target exhaust temperature, and the current coil temperature can be compared with the target coil temperature to determine the operating parameters of the air conditioner.

[0053] Step S206, Adjustment steps: Adjust the current operating frequency of the compressor according to the exhaust temperature difference and the coil temperature difference, and adjust the current speed of the internal fan according to the exhaust temperature difference and the coil temperature difference.

[0054] In this embodiment, when the exhaust temperature difference and the coil temperature difference determine that the current operating frequency of the compressor or the current speed of the indoor fan needs to be adjusted, the current operating frequency of the compressor can be adjusted according to the exhaust temperature difference and the coil temperature difference, and the current speed of the indoor fan can be adjusted according to the exhaust temperature difference and the coil temperature difference, so that the adjusted operating frequency and current speed can enable the air conditioner to adapt to the current operating conditions.

[0055] Step S208, Control steps: Control the compressor to run at the adjusted current operating frequency, and control the internal fan to run at the adjusted current speed.

[0056] As can be seen from the above, in this embodiment of the invention, during the operation of the air conditioner, the current exhaust temperature and the current coil temperature of the outdoor heat exchanger can be obtained through the acquisition step while the air conditioner compressor is running at the current operating frequency and the indoor fan is running at the current speed. Then, through the determination step, the exhaust temperature difference between the current exhaust temperature and the target exhaust temperature is determined, and the coil temperature difference between the current coil temperature and the target coil temperature is determined. Next, through the adjustment step, the current operating frequency of the compressor is adjusted according to the exhaust temperature difference and the coil temperature difference, and the current speed of the indoor fan is adjusted according to the exhaust temperature difference and the coil temperature difference. Finally, through the control step, the compressor is controlled to run at the adjusted current operating frequency, and the indoor fan is controlled to run at the adjusted current speed. This achieves the goal of controlling the operating frequency of the air conditioner compressor and the speed of the indoor fan by the exhaust temperature and the coil temperature of the outdoor unit, enabling the air conditioner to operate reliably under high-temperature conditions, improving the reliability of the air conditioner, and allowing users to experience the cooling effect of the air conditioner normally in hot weather, thereby improving the user experience.

[0057] It is easy to notice that, in this embodiment of the invention, by setting a target exhaust temperature and a target coil temperature, the current exhaust temperature and current coil temperature of the air conditioner can be collected during the operation of the air conditioner. The operating frequency of the air conditioner compressor and the coil temperature of the indoor fan can be compensated according to the relationship between the target exhaust temperature and the target coil temperature and the current exhaust temperature and the current coil temperature. This allows the air conditioner to have a normal cooling effect even under high temperature conditions, and reduces the impact of the installation space on the air conditioner to a certain extent.

[0058] Therefore, the technical solution provided by the embodiments of the present invention solves the technical problem in the related art that the outdoor unit of an air conditioner is easily affected by the installation space under high temperature conditions, and the heat dissipation is poor when the outdoor unit installation space is small and the environment is relatively closed, which will cause the air conditioner to have poor cooling effect.

It will detect the current indoor and outdoor ambient temperatures in the room where the air conditioner is located, and then select the initial operating frequency of the air conditioner's compressor based on the relationship between the current indoor and outdoor ambient temperatures and the preset outdoor and indoor ambient temperatures, respectively.

[0061] In this embodiment, an indoor-outdoor ambient temperature-initial operating frequency mapping table can be established first through experimental data. In subsequent applications, the indoor and outdoor ambient temperatures where the air conditioner is located can be collected, and the target initial operating frequency can be selected from the pre-built indoor-outdoor ambient temperature-initial operating frequency mapping table based on the indoor and outdoor ambient temperatures where the air conditioner is located.

[0062] According to the above embodiments of the present invention, the control method of the air conditioner further includes: during the process of controlling the compressor to operate at the target initial operating frequency, calculating the first duration of the compressor operating at the target initial operating frequency; and when the first duration reaches the first preset operating duration, obtaining the current operating frequency of the compressor and the current speed of the indoor fan.

[0063] In this embodiment, during the process of controlling the compressor to run at the target initial operating frequency, the first duration of the compressor running at the target initial operating frequency is counted.

This includes: when it is determined that the current indoor ambient temperature is not greater than the first preset indoor ambient temperature, selecting a target initial operating frequency from the indoor / outdoor ambient temperature-initial operating frequency mapping table. In the radiation relationship table, the first initial operating frequency is selected as the target initial operating frequency; when the current indoor ambient temperature is determined to be greater than the first preset indoor ambient temperature, the sum of the first initial operating frequency and the first frequency compensation value is selected as the target initial operating frequency from the indoor and outdoor ambient temperature-initial operating frequency mapping relationship table; when the current indoor ambient temperature is determined to be greater than the second preset indoor ambient temperature, the sum of the first initial operating frequency and the second frequency compensation value is selected as the target initial operating frequency from the indoor and outdoor ambient temperature-initial operating frequency mapping relationship table; when the current indoor ambient temperature is determined to be greater than the third preset indoor ambient temperature, the sum of the first initial operating frequency and the third frequency compensation value is selected as the target initial operating frequency from the indoor and outdoor ambient temperature-initial operating frequency mapping relationship table.

[0075] In this embodiment of the invention, the preset outdoor ambient temperature may include a third preset outdoor ambient temperature, and the preset indoor ambient temperature includes a first preset indoor ambient temperature, a second preset indoor ambient temperature, and a third preset indoor ambient temperature. When it is determined that the current outdoor ambient temperature is not less than and is less than the third preset outdoor ambient temperature, a target initial operating frequency is selected from the indoor / outdoor ambient temperature-initial operating frequency mapping table based on the relationship between the current outdoor ambient temperature and the preset outdoor ambient temperature, and the relationship between the current indoor ambient temperature and the preset indoor ambient temperature. This includes: when it is determined that the current indoor ambient temperature is not greater than the first preset indoor ambient temperature, selecting from the indoor / outdoor ambient temperature-initial operating frequency mapping table... Select the third initial operating frequency as the target initial operating frequency; when the current indoor ambient temperature is determined to be greater than the first preset indoor ambient temperature, select the sum of the third initial operating frequency and the first frequency compensation value from the indoor and outdoor ambient temperature-initial operating frequency mapping relationship table as the target initial operating frequency; when the current indoor ambient temperature is determined to be greater than the second preset indoor ambient temperature, select the sum of the third initial operating frequency and the second frequency compensation value from the indoor and outdoor ambient temperature-initial operating frequency mapping relationship table as the target initial operating frequency; when the current indoor ambient temperature is determined to be greater than the third preset indoor ambient temperature, select the sum of the third initial operating frequency and the third frequency compensation value from the indoor and outdoor ambient temperature-initial operating frequency mapping relationship table as the target initial operating frequency.

[0078]

[0079] Figure 6 This is a flowchart illustrating another optional method for selecting the target initial operating frequency according to an embodiment of the present invention, such as... Figure 6 As shown, first measure the indoor and outdoor ambient temperatures, then measure the temperature at T... 外环3 ≤T 外环 When, if T 内环 ≤T 内环1 Then the air conditioner compressor runs at F3 for t1 minutes; if T 内环1 <T 内环 ≤T 内环2 Then the air conditioner compressor runs at F3+ΔF1 for t1 minutes; if T 内环2 <T 内环 ≤T 内环3 Then the air conditioner compressor runs at F3+ΔF2 for t1 minutes; at T 内环3 <T 内环 When the compressor of the air conditioner runs at F3+ΔF3 for t1 minutes, the compressor will run at F3+ΔF3 for t1 minutes.

[0080] As can be seen from the above, in the embodiments of the present invention, both the outdoor and indoor ambient temperatures affect the operating frequency of the compressor after the air conditioner is turned on. Through the technical solution provided by the above embodiments of the present invention, an initial operating frequency matching the current indoor and outdoor ambient temperatures can be selected more accurately, so that the air conditioner operates in a more reasonable mode.

[0081] According to the above embodiments of the present invention, adjusting the current operating frequency of the compressor based on the exhaust temperature difference and the coil temperature difference includes: when it is determined that the current exhaust temperature is less than the target exhaust temperature based on the exhaust temperature difference, and the current coil temperature is less than the target coil temperature based on the coil temperature difference, increasing the current operating frequency to a first predetermined operating frequency; when it is determined that the current exhaust temperature is not greater than the target exhaust temperature based on the exhaust temperature difference and the current coil temperature is equal to the target coil temperature based on the coil temperature difference, or when it is determined that the current exhaust temperature is equal to the target exhaust temperature based on the exhaust temperature difference and the current coil temperature is not greater than the target coil temperature based on the coil temperature difference, determining that there is no need to adjust the current operating frequency; when it is determined that the current exhaust temperature is greater than the target exhaust temperature based on the exhaust temperature difference and the current coil temperature is equal to the target coil temperature based on the coil temperature difference, or when it is determined that the current exhaust temperature is equal to the target exhaust temperature based on the exhaust temperature difference and the current coil temperature is greater than the target coil temperature based on the coil temperature difference, decreasing the current operating frequency to a second predetermined operating frequency.

[0082] In this embodiment, the frequency and indoor fan are controlled based on the exhaust temperature difference and the coil temperature difference.

[0083] Figure 7 This is a flowchart of another optional air conditioner control method according to an embodiment of the present invention, such as... Figure 7 As shown, first, the exhaust temperature of the air conditioner and the coil temperature of the outdoor heat exchanger are detected. Then, the differences between the exhaust temperature and the outdoor coil temperature and the target exhaust temperature and the target outdoor coil temperature are calculated. In other words, the current exhaust temperature and the outdoor heat exchanger coil temperature are detected, the differences between the exhaust temperature and the outdoor coil temperature and the target exhaust temperature and the target outdoor coil temperature are calculated, and the frequency and indoor fan control are executed.

[0084] Where T 排气 <T 目标排气 T 外管 <T 目标外管 If T increases the frequency; 排气 ≤T 目标排气 T 外管 =T 目标外管 , or T 排气 =T 目标排气 T 外管 ≤T 目标外管 Then it continues to run at frequency F0; if T 排气 >T 目标排气 T 外管 =T 目标外管 , or T 排气 =T 目标排气 T 外管 >T 目标外管 If so, then reduce the frequency.

[0085] Furthermore, in this embodiment of the invention, adjusting the current operating frequency of the compressor based on the exhaust temperature difference and the coil temperature difference, and adjusting the current speed of the internal fan based on the exhaust temperature difference and the coil temperature difference, includes: when it is determined that the current exhaust temperature is greater than the target exhaust temperature based on the exhaust temperature difference and the current coil temperature is less than the target coil temperature based on the coil temperature difference, or when it is determined that the current exhaust temperature is less than the target exhaust temperature based on the exhaust temperature difference and the current coil temperature is greater than the target coil temperature based on the coil temperature difference, determining that there is no need to adjust the current operating frequency, and simultaneously controlling the current speed to decrease to a first predetermined speed at a first predetermined rate; when it is determined that the current exhaust temperature is greater than the target exhaust temperature based on the exhaust temperature difference and the current coil temperature is greater than the target coil temperature based on the coil temperature difference, reducing the current operating frequency to a third predetermined operating frequency, and simultaneously controlling the current speed to decrease to a second predetermined speed at a second predetermined rate.

[0086] In this embodiment, the frequency and indoor fan are also controlled based on the exhaust temperature difference and the coil temperature difference.

[0087] like Figure 7 As shown, if T 排气 >T 目标排气 T 外管 <T 目标外管 , or T 排气 <T 目标排气 T 外管 If the target external pipe is T, it will continue to operate at frequency F0, while the indoor fan speed will decrease by 50 rpm / min until the internal fan speed is R. min If T 排气 >T 目标排气 T 外管 >T 目标外管 If the frequency is reduced, the indoor fan speed will be decreased by 50 rpm / min until R... 内转min .

[0088] According to the above embodiments of the present invention, the control method of the air conditioner may further include: during the process of controlling the compressor to operate at the adjusted current operating frequency and controlling the indoor fan to operate at the adjusted current speed, calculating a second duration during which the compressor operates at the adjusted current operating frequency and the indoor fan operates at the adjusted current speed; and when it is determined that the second duration has reached a second preset operating duration, repeatedly executing the acquisition step, the determination step, the adjustment step, and the control step.

[0089] In this embodiment, while the air conditioner compressor is operating at the adjusted current operating frequency and the indoor fan is operating at the adjusted current speed, a second duration t2min is recorded for both operations. Once t2min reaches the preset operating time, the current exhaust temperature and outdoor heat exchanger coil temperature are continuously monitored, and the difference between the exhaust temperature and outdoor coil temperature and the target exhaust temperature and target outdoor coil temperature is calculated. Frequency and indoor fan control are then implemented accordingly.

[0090] In the above embodiments, the determination step is repeatedly performed, including: controlling the target coil temperature to decrease by a predetermined temperature value to obtain the updated target coil temperature, and simultaneously controlling the target exhaust temperature to decrease by a predetermined temperature value to obtain the updated target exhaust temperature; determining the latest exhaust temperature difference between the current exhaust temperature and the updated target exhaust temperature, and determining the latest coil temperature difference between the current coil temperature and the updated target coil temperature.

[0091] That is, in this embodiment of the invention, as the operating time of the air conditioner increases, the comparison objects of the exhaust temperature and the coil temperature are constantly changing during the process of calculating the difference between the exhaust temperature and the outdoor coil temperature and the target exhaust temperature and the target outdoor coil temperature, and executing the control of the frequency and the indoor fan according to the above difference. This makes the adjustment of the operating parameters of the air conditioner more reasonable and also makes the air conditioner more energy-efficient.

[0092] In this embodiment of the invention, the adjustment step is repeatedly executed, including: when the current exhaust temperature is determined to be less than the updated target exhaust temperature based on the latest exhaust temperature difference and the current coil temperature is determined to be equal to the updated target coil temperature based on the latest coil temperature difference, or when the current exhaust temperature is determined to be equal to the updated target exhaust temperature based on the latest exhaust temperature difference and the current coil temperature is determined to be less than the updated target coil temperature based on the coil temperature difference, the current rotation speed is controlled to increase at a third predetermined rate to the rotation speed of the indoor fan after the air conditioner is turned on.

[0093] That is, if T 排气 <T 目标排气 -2,T 外管 =T 目标外管 -2, or T 排气 =T 目标排气 -2,T 外管 <T 目标外管 -2, then the indoor fan speed increases in increments of 30 rpm / min, reaching a maximum of the indoor fan speed R0 after startup; if T 排气 <T 目标排气 -4,T 外管 <T 目标外管If the value is -4, the frequency will increase, and the indoor fan speed will increase by 30 rpm / min, up to a maximum of the indoor fan speed R0 after startup. It will then run at the current frequency and indoor fan speed for t3 minutes. After the air conditioner has run for t3 minutes, the above acquisition, determination, adjustment, and control steps will continue to be executed to ensure the cooling effect of the air conditioner.

[0094] Figure 8 This is a flowchart of another optional air conditioner control method according to an embodiment of the present invention, such as... Figure 8 As shown, the system detects the current exhaust temperature and outdoor heat exchanger coil temperature, calculates the difference between the exhaust temperature and outdoor coil temperature and the target exhaust temperature and target outdoor coil temperature, and controls the frequency and indoor fan accordingly; if T 排气 <T 目标排气 -2,T 外管 =T 目标外管 -2, or T 排气 =T 目标排气 -2,T 外管 <T 目标外管 -2, then the indoor fan speed increases in increments of 30 rpm / min, reaching a maximum of the indoor fan speed R0 after startup; if T 排气 <T 目标排气 -4,T 外管 <T 目 If the external pipe is rated as -4, the frequency will be increased, and the indoor fan speed will increase by 30 rpm / min, reaching a maximum of the indoor fan speed R0 after startup; it will then run at the current frequency and indoor fan speed for t3 minutes.

[0095] In summary, the air conditioner control method provided by the embodiments of the present invention can reliably operate under high-temperature conditions by adjusting the exhaust and outdoor coil temperature control frequency and the indoor fan speed, thereby meeting the cooling needs of air conditioners under high-temperature conditions, allowing users to experience the cooling effect of air conditioners normally under high-temperature conditions, and improving the user's cooling comfort.

Figure 9 This is a schematic diagram of the control device of an air conditioner according to an embodiment of the present invention, such as... Figure 9 As shown, the control device of the air conditioner includes: an acquisition unit 91, a determination unit 93, an adjustment unit 95, and a control unit 97. The control device of the air conditioner will be described below.

[0099] The acquisition unit 91 is used to acquire the current exhaust temperature of the air conditioner and the current coil temperature of the outdoor heat exchanger of the air conditioner while the compressor of the air conditioner is running at the current operating frequency and the indoor fan of the air conditioner is running at the current speed.

[0104] As can be seen from the above, in the solution described in the above embodiments of the present invention, the acquisition unit can acquire the current exhaust temperature of the air conditioner and the current coil temperature of the outdoor heat exchanger of the air conditioner while the compressor of the air conditioner is running at the current operating frequency and the indoor fan of the air conditioner is running at the current speed. Then, the determination unit determines the exhaust temperature difference between the current exhaust temperature and the target exhaust temperature, and determines the coil temperature difference between the current coil temperature and the target coil temperature. Next, the adjustment unit adjusts the current operating frequency of the compressor according to the exhaust temperature difference and the coil temperature difference, and adjusts the current speed of the indoor fan according to the exhaust temperature difference and the coil temperature difference. The control unit controls the compressor to run at the adjusted current operating frequency and controls the indoor fan to run at the adjusted current speed. This achieves the goal of controlling the operating frequency of the air conditioner's compressor and the speed of the air conditioner's indoor fan by the exhaust temperature of the air conditioner and the coil temperature of the outdoor unit, so that the air conditioner can operate reliably under high temperature conditions, improving the reliability of the air conditioner and allowing users to experience the cooling effect of the air conditioner normally in hot weather, thereby improving the user experience.

This allows the air conditioner to have a normal cooling effect even under high temperature conditions, and reduces the impact of the installation space on the air conditioner to a certain extent.
