Description

Technical Field

[0001] This application belongs to the field of air conditioning technology, specifically relating to an air conditioning control method, device, air conditioner, and medium. Background Technology

[0002] When an air conditioner switches between fan speeds, it produces the sound of refrigerant flowing, which affects the user experience. As users' demands for quality of life continue to rise, reducing refrigerant noise during air conditioner adjustments is becoming increasingly important.

[0003] In existing technology, when an air conditioner switches airflow, after determining the target operating frequency of the compressor corresponding to the target airflow, the compressor starts to adjust its operating frequency. The expansion valve adjusts its opening according to the change in the compressor's operating frequency. That is, the expansion valve adjusts its opening once the compressor adjusts its operating frequency, until the compressor adjusts to the target operating frequency and the expansion valve adjusts to the opening corresponding to the compressor's target operating frequency, thus completing the airflow switching.

[0004] However, due to the lag in the adjustment of the expansion valve opening, the compressor frequency has already started the next adjustment before the expansion valve has finished adjusting its opening according to the frequency of the previous compressor adjustment. This causes a mismatch between the compressor frequency and the opening of the expansion valve, resulting in a louder refrigerant noise from the air conditioner. Summary of the Invention

[0046] First, those skilled in the art should understand that these embodiments are merely for explaining the technical principles of this application and are not intended to limit the scope of protection of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0047] Secondly, it should be noted that in the description of the embodiments in this application, terms such as "first," "second," and "third" are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate, so that the embodiments described herein can also be implemented in sequences other than those illustrated or described in this application. Terms such as "inner" and "outer," indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are merely for ease of description, not to indicate or imply that a device or component must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this application.

[0048] Furthermore, it should be noted that, in the description of the embodiments of this application, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] As users' living standards improve and they pursue a higher quality of life, the loud refrigerant flow noise generated during air conditioner airflow adjustment can affect the user experience. Therefore, reducing refrigerant noise during air conditioner adjustment is of great significance.

[0051] In existing technology, when an air conditioner receives a user instruction to switch the airflow, it adjusts the target operating frequency of the compressor according to the target airflow speed to be adjusted. Then, the expansion valve adjusts its opening according to the change in the compressor's operating frequency. That is, when the compressor adjusts its operating frequency, the expansion valve adjusts its opening once, until the compressor adjusts to the target operating frequency and the expansion valve adjusts to the opening corresponding to the compressor's target operating frequency, thus completing the airflow switch.

[0052] However, the adjustment of the expansion valve opening is lagging. It is easy for the expansion valve to not have finished adjusting its opening according to the frequency of the previous compressor adjustment, while the compressor frequency has already started the next adjustment. This causes a mismatch between the compressor frequency and the expansion valve opening, which makes the refrigerant noise emitted by the air conditioner louder and affects the user experience.

[0053] Therefore, in view of the above-mentioned technical problems of the prior art, this application provides an air conditioning control method, device, air conditioner, and medium. By controlling the compressor to operate at a target frequency corresponding to the target wind speed according to the target wind speed, and operating at the target operating frequency for a certain period of time, the opening of the expansion valve is adjusted during this period of time, so that the frequency of the compressor matches the opening of the expansion valve, thereby reducing the excessive refrigerant noise caused by mismatch.

[0054] The principles and features of the embodiments of this application are described below with reference to the accompanying drawings. The examples given are only used to explain the embodiments of this application and are not intended to limit the scope of the embodiments of this application.

[0055] Figure 1 This is a schematic diagram of a scenario for an air conditioning control method provided in this application, such as... Figure 1 As shown, this application scenario includes: air conditioner 101, compressor 102, expansion valve 103, condenser 104, and evaporator 105. When air conditioner 101 receives a fan speed switching signal and switches the airflow, compressor 102 operates at the target frequency, converting the refrigerant in the air conditioner into a high-pressure, high-temperature gas. This gas then passes through condenser 104, becoming a high-pressure, medium-temperature water vapor mixture, and enters expansion valve 103 as a low-pressure, low-temperature liquid. The opening of expansion valve 103 regulates the refrigerant flow rate, cooling the intake air, which in turn determines the airflow. Finally, the refrigerant passes through evaporator 105 to exchange heat with the indoor air. Therefore, by adjusting compressor 102 and expansion valve 103, the airflow of the air conditioner can be adjusted to the target airflow.

[0056] It should be noted that the application scenario of this application only exemplarily shows the device related to this application, and does not limit whether other devices are included. In addition, it does not limit the actual form and connection method of various devices in the application scenario, nor does it limit the interaction method between devices. In the specific application of the solution, it can be set according to actual needs.

[0057] Figure 2 This is a flowchart illustrating an air conditioning control method provided in Embodiment 1 of this application. The executing entity of this method can be an air conditioning control device or equipment, such as an air conditioner with control functions. The method in this embodiment can be implemented through software, hardware, or a combination of both. Figure 2 As shown, the method specifically includes the following steps:

[0058] S201. Obtain the target wind speed for air conditioning control.

[0059] In this embodiment, an air conditioner is used as the execution subject. The air conditioner first detects whether there is a fan speed switching signal. The fan speed switching signal can be sent by a user's mobile terminal that has communication capabilities with the air conditioner, such as a mobile phone, tablet computer, or portable device. Alternatively, it can be sent by the user directly touching the air conditioner's control panel.

[0060] If a wind speed switching signal is detected, the target wind speed corresponding to the wind speed switching signal is determined according to the pre-set correspondence between the wind speed switching signal and the wind speed.

[0061] In this embodiment, a correspondence table between wind speed switching signals and wind speeds can be determined based on experience or simulation experiments. This table can be stored in the air conditioner's control unit or in a server, from which the air conditioner can retrieve the correspondence. Alternatively, a target wind speed can be calculated based on the acquired wind speed switching signal using a certain algorithm and model. It is understood that there are other ways to obtain the target wind speed; this application is merely illustrative and does not limit the scope of the invention.

[0062] S202. Control the air conditioning compressor frequency to adjust to the target frequency corresponding to the target wind speed.

[0063] Taking air conditioning as an example, when switching the air volume, the air volume can be determined by controlling the flow rate of the refrigerant in the cooling cycle, and the flow rate of the refrigerant can be adjusted by setting the frequency of the air conditioning compressor.

[0064] The air conditioner compressor plays the role of compressing and driving the refrigerant in the air conditioner refrigerant circuit. It increases the temperature and pressure of the low-temperature, low-pressure refrigerant vapor that is drawn in, so that the refrigerant in the pipeline can flow.

[0065] After obtaining the target wind speed, the compressor frequency is controlled to increase or decrease to the target frequency according to a preset rate of increase / decrease. The target wind speed and target frequency have a corresponding relationship, which is pre-stored. The method of storing this relationship is the same as that used in step S201 to store the correspondence between the wind speed switching signal and the wind speed, and will not be repeated here.

[0066] S203. Within the first preset time period during which the compressor maintains the target frequency, control the opening of the air conditioning expansion valve until the air conditioning expansion valve reaches the target opening so that the air conditioner reaches the target fan speed. The target opening is determined by the exhaust temperature of the air conditioning compressor.

[0067] The expansion valve is also an important component of the air conditioning system. Its function is to throttle the medium-temperature, high-pressure liquid refrigerant flowing from the condenser into low-temperature, low-pressure wet vapor. The opening degree of the expansion valve can determine the flow rate of the refrigerant.

[0068] After the compressor is adjusted to the target frequency, it is kept running for a preset time. During this time, the opening of the expansion valve is controlled to reach the target opening. By adjusting the opening, the circulation of refrigerant is controlled, so that the air conditioner outputs the target fan speed.

[0069] The target opening degree is determined by the exhaust temperature of the air conditioning compressor because the opening degree of the expansion valve determines the amount of refrigerant circulating, cooling the intake air, which in turn cools the compressor and lowers its exhaust temperature. When the compressor's exhaust temperature meets certain conditions as the expansion valve opening changes, the target fan speed is considered to have been reached. Therefore, the target opening degree of the expansion valve can be determined by the exhaust temperature of the air conditioning compressor.

[0070] In the above embodiments of this application, by obtaining the target fan speed for air conditioning control and controlling the air conditioning compressor frequency to adjust to the target frequency corresponding to the target fan speed, the opening of the air conditioning expansion valve is controlled within a first preset time period during which the compressor maintains operation at the target frequency, until the air conditioning expansion valve reaches the target opening to enable the air conditioning to achieve the target fan speed. The target opening is determined by the exhaust temperature of the air conditioning compressor. This embodiment's method, by controlling the expansion valve to complete the adjustment within the first preset time period during which the compressor maintains operation at the target frequency, ensures that the compressor frequency matches the opening of the expansion valve, thereby reducing refrigerant noise generated during air conditioning adjustment.

[0071] Furthermore, based on step S203 in the above embodiment one, the following embodiment two will describe in detail the process of controlling the opening degree of the air conditioning expansion valve to reach the target opening degree within a first preset time period during which the compressor maintains operation at the target frequency.

[0072] First, let's explain how to determine the target opening degree of the expansion valve.

[0073] Specifically,

[0074] The first exhaust temperature of the air conditioner compressor is detected when the compressor frequency is adjusted to the target frequency.

[0075] The second exhaust temperature of the air conditioner compressor is detected during the control of the air conditioner expansion valve. The compressor exhaust temperature can be detected once at preset intervals, or in real time; this application does not limit the detection to either method.

[0076] When the temperature difference between the first exhaust temperature and the second exhaust temperature meets the first preset threshold, the current opening degree of the air conditioning expansion valve is determined as the target opening degree. The first preset threshold can be set based on empirical values.

[0077] Next, the control process of the expansion valve opening is explained during the first preset time period when the compressor maintains operation at the target frequency.

[0078] One possible implementation is:

[0079] S301. Adjust the opening of the air conditioning expansion valve with the first preset step size.

[0080] S302. Within a first preset time period, the temperature difference between the first exhaust temperature and the second exhaust temperature is calculated at intervals of a second preset time period, wherein the first preset time period is longer than the second preset time period.

[0081] S303. When the temperature difference is less than the second preset threshold, the opening of the air conditioning expansion valve is adjusted by the second preset step size until the air conditioning expansion valve reaches the target opening size within the first preset time period. The first preset step size is less than the second preset step size.

[0082] For example,

[0083] Assuming a first preset duration of 10 seconds and a second preset duration of 5 seconds, with a first preset step size ΔPs1 of 1 step / second, the temperature difference Δt between the first and second exhaust temperatures is calculated every 5 seconds. If Δt is less than the second preset threshold T2, the air conditioning expansion valve opening is adjusted at a second preset step size ΔPs2 of 3 steps / second until the air conditioning expansion valve reaches the target opening within 10 seconds. By accelerating the expansion valve opening adjustment rate, i.e., increasing the step value, it is ensured that the opening adjustment is completed within 10 seconds.

[0084] Another possible implementation is:

[0085] S401. Adjust the opening of the air conditioning expansion valve by the first preset step size.

[0086] S402. Within the first preset duration, the temperature difference between the first exhaust temperature and the second exhaust temperature is calculated every third preset duration, wherein the first preset duration is longer than the third preset duration.

[0087] S403. Based on the temperature difference value, determine the temperature difference threshold range to which the temperature difference value belongs.

[0088] S404. Determine the third preset step size corresponding to the temperature difference value based on the temperature difference range.

[0089] S405. Adjust the opening of the air conditioning expansion valve with the third preset step size until the air conditioning expansion valve reaches the target opening size within the first preset time period.

[0090] For example,

[0091] Assuming the first preset duration is 10 seconds and the third preset duration is 2 seconds, the temperature difference Δt between the first and second exhaust temperatures is calculated every 2 seconds. Based on the correspondence between the preset Δt and the third preset step size, the third preset step size is determined to be ΔPs3. If Δt is 4℃, according to Table 1, ΔPs3 is determined to be 3 steps / second. The opening of the air conditioning expansion valve is adjusted at 3 steps / second until the air conditioning expansion valve reaches the target opening within 10 seconds. The correspondence table is shown in Table 1.

[0092] Δt / ℃ 1-5 6-10 11-15 ΔPs3 / Steps / s 3 4 5

[0093] It is understood that the data in Table 1 is for illustrative purposes only and is not intended to limit this application. Specific data can be set according to requirements.

[0094] In the above embodiments of this application, within a first preset time period during which the compressor maintains operation at the target frequency, the opening of the air conditioning expansion valve is adjusted by a first preset step size. Within the first preset time period, the temperature difference between the first exhaust temperature and the second exhaust temperature is calculated at second preset time intervals. When the temperature difference is less than a second preset threshold, the opening of the air conditioning expansion valve is adjusted by a second preset step size until the air conditioning expansion valve reaches the target opening within the first preset time period. Alternatively, within the first preset time period, the temperature difference between the first exhaust temperature and the second exhaust temperature is calculated every third preset time interval. Based on the temperature difference, a temperature difference threshold range to which the temperature difference belongs is determined. Based on the range to which the temperature difference belongs, a third preset step size is determined, and the opening of the air conditioning expansion valve is adjusted by the third preset step size until the air conditioning expansion valve reaches the target opening within the first preset time period. The method of this embodiment matches the compressor frequency with the opening of the expansion valve, reducing refrigerant noise emitted during air conditioning adjustment.

[0106] When the temperature difference is less than the second preset threshold, the opening of the air conditioning expansion valve is adjusted by the second preset step size until the air conditioning expansion valve reaches the target opening size within the first preset time period. The first preset step size is less than the second preset step size.

[0107] One possible implementation is that the control module 302 is further used for:
