Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to an air conditioning control method, device, equipment and storage medium. Background Technology

[0002] A dual-split air conditioner consists of one outdoor unit and two indoor units. By adjusting the refrigerant in the piping of the two indoor units, both indoor units can achieve the expected air conditioning requirements. The two indoor units can be designed for different application scenarios.

[0003] Air conditioners typically have cooling and heating modes. For individual indoor units, refrigerant circulation occurs through a loop: compressor-outdoor unit (usually called condenser)-throttling device (such as expansion valve)-indoor unit (usually called evaporator)-compressor. This ensures the indoor space receives the desired air temperature. In a dual-split air conditioner, refrigerant is regulated by the outdoor unit using two throttling devices (such as electronic expansion valves) to control the refrigerant flow to each indoor unit. During the manufacturing process, because the expansion valves and temperature sensors in each indoor unit are similar or identical, assembly personnel can easily misinstall them. Misinstallation leads to poor control accuracy. Summary of the Invention

[0049] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0050] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0051] Below, in conjunction with Figure 1 The application scenarios of the embodiments of this application will be introduced.

[0052] Figure 1 This is a schematic diagram illustrating an application scenario provided by an embodiment of this application. Please refer to [link / reference]. Figure 1 This includes an air conditioner. The air conditioner has a first indoor unit, a second indoor unit, and an outdoor unit, with the first and second indoor units connected to the outdoor unit respectively. The first and second indoor units are connected to the outdoor unit via a thick pipe, which supplies refrigerant from the outdoor unit's compressor to the heat exchangers of the first and second indoor units. The first and second indoor units are also connected to the outdoor unit via a thin pipe, which contains an expansion valve. Refrigerant flowing from the heat exchangers of the first and second indoor units enters the outdoor unit's heat exchanger via the thin pipe and the expansion valve. A thick pipe temperature sensor is installed in the thick pipe to detect its temperature, and a thin pipe temperature sensor is installed in the thin pipe to detect its temperature. These two temperature sensors form a thick-thin pipe temperature sensor group.

[0053] Figure 1 In the diagram, the air conditioner's control circuit board has multiple preset mounting positions, allowing relevant components to be electrically connected to the control circuit board at these positions. From left to right, the preset mounting positions are: the preset mounting position of the coarse and fine tube temperature sensor group of the first indoor unit, the preset mounting position of the coarse and fine tube temperature sensor group of the second indoor unit, the preset mounting position of the expansion valve of the first indoor unit, and the preset mounting position of the expansion valve of the second indoor unit. For ease of understanding, each expansion valve and coarse and fine tube temperature sensor group is connected to its corresponding preset mounting position by a dotted line.

[0054] In related technologies, during the air conditioner manufacturing process, because the expansion valves and temperature sensors of each indoor unit are of the same or similar style, assembly personnel can easily install them incorrectly. If this misinstallation occurs, it will lead to poor control accuracy of the air conditioner. For example, taking a unit with two indoor units as an example, if only one indoor unit is turned on, or if the target temperatures of the two indoor units are different, the air conditioner may execute the correct program but produce opposite control effects on the indoor units.

[0055] To overcome the above problems, embodiments of this application provide an air conditioner control method, device, equipment, and storage medium that can determine whether the expansion valve or temperature sensor of the indoor unit is misaligned, and can interchange the corresponding parameters of the indoor unit when misalignment occurs, so as to ensure the control accuracy of the air conditioner.

[0056] The technical solutions shown in this application will now be described in detail through specific embodiments. It should be noted that the following embodiments may exist independently or in combination with each other; identical or similar content will not be repeated in different embodiments.

[0057] Figure 2 This is a schematic flowchart illustrating an air conditioner control method provided in an embodiment of this application. Please refer to... Figure 2 The control method may include:

[0058] S201. In detection mode, obtain the operating parameters of the first indoor unit and the second indoor unit; wherein, in detection mode, the first indoor unit is in operation and the expansion valve of the second indoor unit is in closed state.

[0059] The executing entity in this application embodiment can be an air conditioner or a control device for the air conditioner installed in the air conditioner. Optionally, the control device for the air conditioner can be implemented by software or by a combination of software and hardware.

[0060] After the air conditioner is powered on, it enters detection mode, controlling the first indoor unit to run and the expansion valve of the second indoor unit to close, acquiring the operating parameters of both indoor units. Specifically, the detection mode is entered every time the air conditioner is powered on, such as upon initial power-on or after a power cycle, to promptly detect any installation misalignment.

[0061] In this embodiment, whether the first indoor unit is running alone or in dual-unit operation, after entering the detection mode, the first indoor unit can be controlled to be in operation, and the expansion valve of the second indoor unit can be controlled to be in the closed state.

[0062] Furthermore, for ease of description, this embodiment uses two indoor units as an example. In other embodiments, there may be three or more indoor units.

[0063] In other embodiments, when the second indoor unit is running alone or in pairs, after entering the detection mode, the second indoor unit can also be controlled to be in operation while the expansion valve of the first indoor unit is controlled to be closed. The implementation process is similar to that in this embodiment.

[0064] S202. Compare the operating parameters of the first indoor unit and the operating parameters of the second indoor unit.

[0065] S203. When it is determined that the comparison result meets the misalignment condition, the air conditioner is controlled to enter the correction mode; wherein, in the correction mode, the parameters of the misaligned components corresponding to the first indoor unit and the second indoor unit are interchanged.

[0066] In this embodiment, it is determined whether the relationship between the operating parameters of the first indoor unit and the second indoor unit meets the misalignment condition. If the relationship between the operating parameters of the first indoor unit and the second indoor unit meets the misalignment condition, it is determined that the corresponding components of the first indoor unit and the second indoor unit are misaligned. Then, the air conditioner is controlled to enter the correction mode to interchange the parameters of the misaligned components of the first indoor unit and the second indoor unit, thereby ensuring that the first indoor unit and the second indoor unit operate accurately according to the user's cooling or heating needs.

[0067] The misalignment conditions are set and stored in advance based on the magnitude relationship of the corresponding operating parameters when the relevant components are misaligned under different working conditions.

[0068] For example, when the operating parameter is the indoor unit coil temperature, if the relationship between the coil temperatures of the first indoor unit and the second indoor unit meets the misalignment condition, it is determined that the expansion valves of the first indoor unit and the second indoor unit are misaligned. The air conditioner is then controlled to enter correction mode so that the relevant parameters of the expansion valves, such as the pressure, of the expansion valves of the first indoor unit and the second indoor unit can be interchanged when the system is activated.

[0069] When the operating parameter is the coarse pipe temperature, if the relationship between the coarse pipe temperatures of the first indoor unit and the second indoor unit meets the misalignment condition, it is determined that the coarse and fine pipe temperature sensor groups of the first indoor unit and the second indoor unit are installed in a misaligned manner. The air conditioner is then controlled to enter a correction mode so that the coarse pipe temperature and fine pipe temperature of the first indoor unit and the second indoor unit can be interchanged when the mode is called.

[0070] When the comparison result meets the misalignment condition, the installation position of the misaligned component is recorded in the air conditioner's control circuit board so that the air conditioner in correction mode can directly call the correct parameters, thereby reducing the number of tests.

[0071] In addition, before step S203, the method further includes: obtaining the current operating condition of the air conditioner and obtaining the misalignment condition corresponding to the current operating condition. The operating conditions of the air conditioner include cooling and heating conditions, and the misalignment conditions are different for cooling and heating conditions.

[0072] The control method provided by the embodiment of the present application obtains the operating parameters of the first indoor unit and the second indoor unit in the detection mode. Among them, in the detection mode, the first indoor unit is in the operating state, and the expansion valve of the second indoor unit is in the closed state. Compare the operating parameters of the first indoor unit with those of the second indoor unit. When it is determined that the comparison result meets the misalignment condition, control the air conditioner to enter the correction mode. Among them, in the correction mode, the parameters of the misaligned components are swapped. In this way, it is possible to detect whether there is misalignment of the components corresponding to the indoor units, and when misalignment occurs, the corresponding parameters of the indoor units can be swapped to ensure that the first indoor unit and the second indoor unit operate accurately according to the user's cooling or heating requirements, thereby improving the control accuracy of the air conditioner.

[0073] Based on the embodiment shown in Figure 2 , the control method of the above air conditioner will be described in detail below. The control method provided in this embodiment includes: Figure 3

[0074] S301. In the detection mode, obtain the indoor coil temperature Tpa of the first indoor unit, the indoor coil temperature Tpb of the second indoor unit, the thick pipe temperature Tca corresponding to the first indoor unit, and the thick pipe temperature Tcb corresponding to the second indoor unit.

[0075] The implementation process of step S301 is the same as or similar to that of the foregoing step S201, and will not be elaborated here.

[0076] S302. Under the refrigeration condition, determine whether Tpa is greater than Tpb.

[0077] If Tpa > Tpb, it means that the expansion valve is misaligned, and step S303 is executed. If Tpa < Tpb, it is determined that the expansion valve is correctly installed, and step S306 is executed.

[0078] Among them, the misalignment of the expansion valve means that the actual installation position of the expansion valve of the first indoor unit on the control circuit board is the preset installation position of the expansion valve of the second indoor unit on the control circuit board; the actual installation position of the expansion valve of the second indoor unit on the control circuit board is the preset installation position of the expansion valve of the first indoor unit on the control circuit board.

[0079] Correspondingly, the correct installation of the expansion valve means that the actual installation position of the expansion valve of the first indoor unit on the control circuit board is the preset installation position of the expansion valve of the first indoor unit on the control circuit board; the actual installation position of the expansion valve of the second indoor unit on the control circuit board is the preset installation position of the expansion valve of the second indoor unit on the control circuit board.

[0080] S303. Determine whether Tca is less than Tcb.

[0081] If Tca < Tcb, it is determined that the temperature sensor group of the thick and thin pipes is installed out of position, and step S304 is executed. If Tca > Tcb, it is determined that the temperature sensor group of the thick and thin pipes is installed correctly, and step S305 is executed.

[0082] Among them, the installation out of position of the temperature sensor group of the thick and thin pipes means that: the actual installation position of the temperature sensor group of the thick and thin pipes of the first indoor unit on the control circuit board is the preset installation position of the temperature sensor group of the thick and thin pipes of the second indoor unit on the control circuit board; the actual installation position of the temperature sensor group of the thick and thin pipes of the second indoor unit on the control circuit board is the preset installation position of the temperature sensor group of the thick and thin pipes of the first indoor unit on the control circuit board.

[0083] Correspondingly, the correct installation of the temperature sensor group of the thick and thin pipes means that: the actual installation position of the temperature sensor group of the thick and thin pipes of the first indoor unit on the control circuit board is the preset installation position of the temperature sensor group of the thick and thin pipes of the first indoor unit on the control circuit board; the actual installation position of the temperature sensor group of the thick and thin pipes of the second indoor unit on the control circuit board is the preset installation position of the temperature sensor group of the thick and thin pipes of the second indoor unit on the control circuit board.

[0084] Step S304: When called, the pressure of the expansion valve of the first indoor unit is exchanged with the pressure of the expansion valve of the second indoor unit, and the corresponding thick pipe temperature and thin pipe temperature of the first indoor unit are also exchanged with the corresponding thick pipe temperature and thin pipe temperature of the second indoor unit.

[0085] In this embodiment, when Tpa > Tpb and Tca < Tcb, the expansion valve and the temperature sensor group of the thick and thin pipes are installed out of position. The second indoor unit is controlled according to the matching of the thick and thin temperature sensor group of the first indoor unit with the expansion valve of the first indoor unit, and the first indoor unit is controlled according to the matching of the thick and thin temperature sensor group of the second indoor unit with the expansion valve of the second indoor unit.

[0086] Step S305: When called, the pressure of the expansion valve of the first indoor unit is exchanged with the pressure of the expansion valve of the second indoor unit.

[0087] In this embodiment, when Tpa > Tpb and Tca > Tcb, the expansion valve is installed out of position, and the temperature sensor group of the thick and thin pipes is installed correctly. The first indoor unit is controlled according to the matching of the thick and thin temperature sensor group of the first indoor unit with the expansion valve of the second indoor unit, and the second indoor unit is controlled according to the matching of the thick and thin temperature sensor group of the second indoor unit with the expansion valve of the first indoor unit.

[0088] Of course, the parameters called are not limited to the pressure of the expansion valve, and may also include other operating parameters of the expansion valve.

[0089] S306: Determine whether Tca is greater than Tcb.

[0090] If Tca > Tcb, it is determined that the installation of the thick and thin pipe temperature sensor groups is misaligned, and step S307 is executed. If Tca < Tcb, it is determined that the installation of the thick and thin pipe temperature sensor groups is correct, and the pressures of the expansion valves of the first indoor unit and the second indoor unit are normally called, and the thick pipe temperature, thin pipe temperature corresponding to the first indoor unit and the thick pipe temperature, thin pipe temperature corresponding to the second indoor unit are normally called.

[0091] S307. When calling, swap the thick pipe temperature, thin pipe temperature corresponding to the first indoor unit and the thick pipe temperature, thin pipe temperature corresponding to the second indoor unit.

[0092] In this embodiment, when Tpa < Tpb and Tca > Tcb, the expansion valve is installed correctly, and the thick and thin pipe temperature sensor groups are installed misaligned. The second indoor unit is controlled according to the matching of the thick and thin temperature sensor groups of the first indoor unit and the expansion valve of the second indoor unit, and the first indoor unit is controlled according to the matching of the thick and thin temperature sensor groups of the second indoor unit and the expansion valve of the first indoor unit.

In the detection mode, obtain the indoor coil temperature Tpa of the first indoor unit, the indoor coil temperature Tpb of the second indoor unit, the thick pipe temperature Tca corresponding to the first indoor unit, and the thick pipe temperature Tcb corresponding to the second indoor unit.

[0095] The implementation process of step S401 is the same as or similar to the implementation process of the前述 step S201, and will not be elaborated here.

[0096] S402. In the heating condition, judge whether Tpa is less than Tpb.

[0097] If Tpa < Tpb, the expansion valve is installed misaligned, and step S403 is executed. If Tpa > Tpb, it is determined that the expansion valve is installed correctly, and step S406 is executed.

[0098] S403. Judge whether Tca is greater than Tcb.

[0099] If Tca > Tcb, it is determined that the installation of the thick and thin pipe temperature sensor groups is misaligned, and step S404 is executed. If Tca < Tcb, it is determined that the installation of the thick and thin pipe temperature sensor groups is correct, and step S405 is executed. [[ID=Z32]]

[0100] S404. When calling, swap the pressures of the expansion valves of the first indoor unit and the second indoor unit, and also swap the thick pipe temperature, thin pipe temperature corresponding to the first indoor unit and the thick pipe temperature, thin pipe temperature corresponding to the second indoor unit.

[0101] In this embodiment, when Tpa < Tpb and Tca > Tcb, the expansion valve and the thick and thin pipe temperature sensor group are installed out of alignment. Control the second indoor unit according to the matching of the thick and thin temperature sensor group of the first indoor unit and the expansion valve of the first indoor unit, and control the first indoor unit according to the matching of the thick and thin temperature sensor group of the second indoor unit and the expansion valve of the second indoor unit.

Control the first indoor unit according to the matching of the thick and thin temperature sensor group of the first indoor unit and the expansion valve of the second indoor unit, and control the second indoor unit according to the matching of the thick and thin temperature sensor group of the second indoor unit and the expansion valve of the first indoor unit.

[0104] S406: Determine whether Tca is less than Tcb.

[0105] If Tca < Tcb, it is determined that the thick and thin pipe temperature sensor group is installed out of alignment, and step S407 is executed.
