Description

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] When an air conditioner is running, it determines the control thresholds of some functions based on the outdoor ambient temperature where the outdoor unit is located. These thresholds not only affect the performance of the air conditioner, but also its reliability. Accurate outdoor ambient temperature is an indispensable and important parameter to ensure the efficient and reliable operation of the air conditioner. Therefore, it is very important to accurately obtain the outdoor ambient temperature.

[0003] Currently, the most common method for measuring outdoor ambient temperature is by attaching an external ambient temperature sensor near the heat exchanger of the outdoor unit. While this method is reliable and highly accurate, it is relatively expensive. Using a thermistor NTC can reduce both hardware and labor costs, making it an economical and practical temperature measurement method. However, this method requires soldering the sensor onto the outdoor unit's main board. The temperature obtained at this point is the temperature on the main board, which is easily affected by the heat generated by the main board and the compressor cavity temperature, and therefore cannot directly reflect the actual ambient temperature.

[0004] Regarding the issue that the method used to obtain the outdoor ambient temperature during the operation of the air conditioner is easily affected by the heat of the air conditioner's main board and the temperature of the compressor cavity, resulting in the obtained outdoor ambient temperature not directly reflecting the actual outdoor ambient temperature, no effective solution has yet been proposed.

[0036] As described in the background section, in related technologies, the methods used to obtain the outdoor ambient temperature during air conditioner operation are easily affected by the heat generated by the air conditioner's mainboard and the compressor cavity temperature, resulting in the obtained outdoor ambient temperature not directly reflecting the actual outdoor ambient temperature.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0038] The methods and embodiments provided in this invention can be executed on a mobile terminal, a computer terminal, or a similar computing device. Taking running on a mobile terminal as an example, Figure 1 This is a hardware structure block diagram of a mobile terminal for an air conditioner control method according to an embodiment of the present invention. Figure 1 As shown, a mobile terminal may include one or more ( Figure 1 Only one is shown in the diagram.

[0040] 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.

[0041] 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:

[0042] Step S202: During the operation of the air conditioner according to the initial operation strategy at startup, the relevant temperature values ​​of the outdoor unit of the air conditioner are obtained. The relevant temperature values ​​of the outdoor unit include: the pipe temperature of the condenser of the outdoor unit and the exhaust temperature of the compressor of the outdoor unit.

[0043] In this embodiment, after the air conditioner receives the start signal and starts, it will operate according to the corresponding operating strategy, i.e., the initial operating strategy. During its operation according to the initial operating strategy, relevant temperature values ​​of the outdoor unit can be acquired, such as the pipe temperature of the outdoor unit's condenser and the exhaust temperature of the outdoor unit's compressor. Based on these relevant outdoor unit temperature values, it can be determined whether the current operating state of the air conditioner is stable, and thus the next operating strategy of the air conditioner can be determined.

[0044] Step S204: Determine the pipe temperature change value within a predetermined time period and determine the exhaust temperature change value within a predetermined time period.

[0045] In this embodiment, the condenser pipe temperature change value and exhaust temperature change value can be determined based on the outdoor unit temperature values ​​obtained in the above steps.

[0046] For example, the temperature change of the condenser tubes and the temperature change of the compressor discharge temperature within 5 minutes can be detected to determine whether the air conditioner is operating stably.

[0047] Step S206: When the pipe temperature change value is less than the first temperature threshold and the exhaust temperature change value is less than the second temperature threshold, the outer ring temperature correction parameter of the air conditioner is obtained. The outer ring temperature correction parameter is used to correct the outdoor ambient temperature of the air conditioner.

[0048] In this embodiment, the pipe temperature change value and exhaust temperature change value obtained in the above steps can be compared with the corresponding temperature thresholds, such as the first temperature threshold and the second temperature threshold, to determine whether the air conditioner is in a stable operating state.

[0049] For example, when the change in the external pipe temperature T_external pipe within 5 minutes is less than a℃ (where a ranges from 1 to 3), and the change in the exhaust temperature T_exhaust within 5 minutes is less than b℃ (where b ranges from 1 to 7), it is considered that the system operating parameters are basically stable. Then, the outer ring temperature correction parameters used to correct the outdoor ambient temperature of the air conditioner can be obtained, such as pipe temperature, exhaust temperature, resistance temperature of the thermistor NTC set on the outdoor unit of the air conditioner, current value of the outdoor unit, and speed of the outdoor fan.

[0050] Step S208: Determine the target outdoor ambient temperature corresponding to the outer ring temperature correction parameter, update the initial operation strategy according to the target outdoor ambient temperature, and control the air conditioner to operate according to the updated initial operation strategy.

[0051] In this embodiment, the target outdoor ambient temperature corresponding to the outer ring temperature correction parameter can be determined. The initial operating strategy can then be updated based on the target outdoor ambient temperature, and the air conditioner can be controlled to operate according to the updated initial operating strategy, so that the operation of the air conditioner is more in line with the actual environment and provides a better user experience.

[0052] It should be noted here that there are several ways to determine the target outdoor ambient temperature. For example, a mapping relationship between the outer ring temperature correction parameter and the outdoor ambient temperature can be established in advance, and the corresponding target outdoor ambient temperature can be searched from the mapping relationship based on the outer ring temperature correction parameter. Alternatively, an outdoor ambient temperature correction model can be constructed to determine the target outdoor ambient temperature corresponding to the outer ring temperature correction parameter. Of course, other methods are also possible, and no specific limitations are made here.

[0053] As described above, in this embodiment of the invention, during the operation of the air conditioner according to the initial operating strategy at startup, the relevant temperature values ​​of the outdoor unit of the air conditioner are obtained. These outdoor unit temperature values ​​include: the pipe temperature of the condenser of the outdoor unit and the exhaust temperature of the compressor of the outdoor unit. The pipe temperature change value within a predetermined time period and the exhaust temperature change value within the predetermined time period are determined. When the pipe temperature change value is less than a first temperature threshold and the exhaust temperature change value is less than a second temperature threshold, the outer loop temperature correction parameter of the air conditioner is obtained. This outer loop temperature correction parameter is used to correct the outdoor ambient temperature of the air conditioner. The target outdoor ambient temperature corresponding to the outer loop temperature correction parameter is determined, and the initial operating strategy is updated based on the target outdoor ambient temperature. The air conditioner is then controlled to operate according to the updated initial operating strategy. This achieves the goal of correcting the initial outdoor ambient temperature of the air conditioner by collecting the outer loop temperature correction parameter when the air conditioner is operating stably, and updating the current operating strategy of the air conditioner using the corrected outdoor ambient temperature. This makes the air conditioner's operation mode more suitable for the current environment and provides a more comfortable environment for the user.

[0054] It is worth noting that, in this embodiment of the invention, the outdoor ambient temperature of the outdoor unit of the air conditioner is continuously corrected according to the outer ring temperature correction parameter to obtain a target outdoor ambient temperature that is closer to the actual outdoor ambient temperature. This target outdoor ambient temperature is then used to update the current operating strategy of the air conditioner, which makes the operation of the air conditioner more in line with the current environment, thus providing a better environment for the user.

[0055] Therefore, the technical solution provided by the above embodiments of the present invention solves the technical problem in the related art that the method for obtaining the outdoor ambient temperature of the air conditioner during the operation of the air conditioner is easily affected by the heating of the air conditioner's main board and the temperature of the compressor cavity, resulting in the obtained outdoor ambient temperature not being able to directly reflect the actual outdoor ambient temperature.

[0056] According to the above embodiments of the present invention, during the operation of the air conditioner according to the initial operating strategy at startup, obtaining the relevant temperature value of the outdoor unit of the air conditioner may include: after the air conditioner is turned on, determining the initial outdoor ambient temperature of the air conditioner for this startup according to the operating mode of the air conditioner; and determining the initial operating strategy of the air conditioner according to the initial outdoor ambient temperature.

[0057] In this embodiment, after the air conditioner is turned on, for example, the user controls the air conditioner to start by pressing the remote control that is paired with the air conditioner, or by issuing a voice command. After receiving the start signal, the system will determine the initial outdoor ambient temperature of the air conditioner for this start-up based on the air conditioner's operating mode, and then determine the initial operating strategy of the air conditioner based on the initial outdoor ambient temperature, and control the air conditioner to operate according to the initial operating strategy.

[0058] In the above embodiments, determining the initial outdoor ambient temperature for the current start-up of the air conditioner based on its operating mode includes: when the operating mode is heating mode, determining the historical outdoor ambient temperature recorded when the air conditioner was last turned off as the initial outdoor ambient temperature; when the operating mode is cooling mode, determining the condenser pipe temperature detected by the condenser temperature sensor at the moment the air conditioner is turned on as the initial outdoor ambient temperature.

[0059] In this embodiment, when the air conditioner is in heating mode, the outer ambient temperature (T_outer ring) recorded from the last shutdown time is used as the outer ambient temperature for this startup to control related functions. In other words, the historical outdoor ambient temperature recorded from the last shutdown time is used as the initial outdoor ambient temperature for controlling related functions. When the air conditioner is in cooling mode, the outer pipe temperature (T_outer pipe) detected by the outdoor condenser temperature sensor at the startup time is used as the outer ambient temperature for controlling related functions. In other words, when the air conditioner is in cooling mode, the condenser pipe temperature detected by the condenser temperature sensor at the startup time is used as the initial outdoor ambient temperature for controlling related functions.

[0060] By selecting different initial outdoor ambient temperatures for different operating modes to control related functions, the control of the air conditioner can be more accurate and better meet the user's needs for environmental comfort.

[0061] Figure 3 This is a structural diagram of the external ambient temperature measurement and control system according to an embodiment of the present invention, as shown below. Figure 3 As shown, the control system mainly involves the outdoor unit mainboard, temperature sensors, and outdoor fan. The temperature sensors include an outdoor condenser temperature sensor and an exhaust temperature sensor, used to acquire the outdoor pipe temperature and exhaust temperature, respectively (the outdoor pipe temperature affects the mainboard's heat dissipation, and the exhaust temperature affects the compressor cavity temperature; both affect the NTC temperature). The outdoor unit mainboard mainly includes a data acquisition module and an ambient temperature correction module. The data acquisition module acquires the outdoor pipe temperature and exhaust temperature from the temperature sensors, and also acquires the outdoor fan speed and outdoor unit current (the outdoor fan speed affects the mainboard's heat dissipation, and the current directly reflects the outdoor unit mainboard's heat generation, also affecting the NTC temperature). This data is then transmitted to the ambient temperature correction module to calculate the ambient temperature. The ambient temperature correction module mainly consists of an NTC correction model formula. Based on the acquired real-time NTC temperature, condenser outdoor pipe temperature, exhaust temperature, outdoor unit current, and outdoor fan speed, it calculates the corrected ambient temperature, determines its use according to the control logic, and finally inputs it into other related functional programs for control.

[0062] According to the above embodiments of the present invention, before determining the initial outdoor ambient temperature for the current start-up of the air conditioner based on the air conditioner's operating mode, the control method of the air conditioner further includes: acquiring the initial outdoor unit related temperature value detected at the start-up time of the air conditioner; determining the temperature difference between the pipe temperature and the exhaust temperature in the initial outdoor unit related temperature value; determining the operating mode as cooling mode when the temperature difference is less than a third temperature threshold; and determining the operating mode as heating mode when the temperature difference is not less than the third temperature threshold.

[0063] In this embodiment, after the air conditioner is turned on, the external pipe temperature T is monitored in real time. 外管 Exhaust temperature T 排气 The difference between the two values ​​at the time of startup determines whether the startup is a hot start or a cold start, when the exhaust temperature T... 排气 Subtract the external tube temperature T 外管 Less than the judgment threshold V 冷热启动 If the system is in a cold start state, it will determine whether the current boot is a cold start; otherwise, it will determine whether it is a warm start.

[0064] Figure 4 This is a flowchart of an optional air conditioner control method according to an embodiment of the present invention, such as... Figure 4 As shown, firstly, after the air conditioner is turned on, the external pipe temperature T is monitored in real time. 外管 Exhaust temperature T 排气 Next, determine the start-up type of the air conditioner, specifically by checking the start-up time T. 排气 -T 外管 Is it less than V? 冷热启动That is, the third temperature threshold; that is, determining whether the start-up is a hot start or a cold start based on the difference between the two at the time of startup, when the exhaust temperature T 排气 Subtract the external tube temperature T 外管 Less than the judgment threshold V 冷热启动 If the system is in a cold start state, it will determine whether the current boot is a cold start; otherwise, it will determine whether it is a warm start.

[0065] like Figure 4 As shown, when the air conditioner is in a hot start state, the ambient temperature recorded at the time of the last shutdown is used as the ambient temperature for this start; otherwise, the ambient temperature T is used. 外管 As the outer ring temperature.

[0066] According to the above embodiments of the present invention, determining the target outdoor ambient temperature corresponding to the outer ring temperature correction parameter may include: determining the target outdoor ambient temperature corresponding to the outer ring temperature correction parameter through an outdoor ambient temperature correction model, wherein the outdoor ambient temperature correction model is a model obtained by simulation through multiple sets of sample data, the sample outer ring temperature correction parameter in the multiple sets of sample data is the input of the outdoor ambient temperature correction model, and the sample outdoor ambient temperature in the multiple sets of sample data is the output of the outdoor ambient temperature correction model.

[0067] In this embodiment, the target outdoor ambient temperature corresponding to the outer ring temperature correction parameter can be determined by an outdoor ambient temperature correction model.

[0077] In this embodiment, during the process of updating the initial operating strategy according to the target outdoor ambient temperature and controlling the air conditioner to operate according to the updated initial operating strategy, if it is detected that the air conditioner changes its operating mode or is turned off, the outdoor ambient temperature at this time is recorded. The recorded outdoor ambient temperature can be the outdoor ambient temperature at the last time it was turned off, which may be used when the air conditioner is turned on again.

[0078] In other words, during operation, when the air conditioner switches modes or is turned off, the ambient temperature at that time is recorded. The recorded ambient temperature is the ambient temperature at the last time the air conditioner was turned off, which may be used when the air conditioner is turned on again.

[0080] In this embodiment, such as Figure 4 As shown, during the operation of the air conditioner, when the air conditioner changes mode or is turned off, the ambient temperature at this time is recorded. The recorded ambient temperature is the ambient temperature at the last time it was turned off that may be used when the air conditioner is turned on again. After that, the outdoor fan runs continuously for t minutes (the value of t ranges from 1 to 5).

[0081] The technical solutions provided in the embodiments of this invention enable the construction of an NTC temperature correction model, allowing for accurate measurement of outdoor ambient temperature. Furthermore, the temperature correction model ensures the reliability and accuracy of the acquired outdoor ambient temperature results, corrects the NTC-measured temperature to accurately reflect the actual ambient temperature, and sets relevant logic. This allows the NTC to replace the existing air conditioner outdoor unit's temperature sensor for ambient temperature measurement, reducing outdoor unit costs. Therefore, this method of measuring outdoor ambient temperature based on NTC temperature measurement and using a correction model and control method for optimization, ultimately yielding the ambient temperature, can reduce costs by using a low-cost NTC to replace the ambient temperature sensor while maintaining measurement accuracy.

[0086] The first determining unit 53 is used to determine the pipe temperature change value within a predetermined time period and the exhaust temperature change value within a predetermined time period.

[0087] The second acquisition unit 55 is used to acquire the outer ring temperature correction parameters of the air conditioner when the pipe temperature change value is less than the first temperature threshold and the exhaust temperature change value is less than the second temperature threshold.
