The following description is provided to enable any person skilled in the art to make and use the invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the invention can be made without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the invention with unnecessary detail. Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.
[0076] First, let's explain the terms used in this application:
[0077] Air conditioning generally includes several major parts such as cold / heat source equipment, cold / heat medium distribution system, terminal units, and other auxiliary equipment. It mainly includes the refrigeration unit, water pump, fan, and piping system. The terminal units are responsible for utilizing the distributed cold or heat to specifically process the air condition, ensuring that the air parameters of the target environment meet certain requirements.
[0078] Indoor coil temperature: The temperature of the indoor unit coil of the air conditioner. This temperature depends on several factors, including indoor air temperature, humidity, the cooling or heating capacity of the air conditioning system, and the operating status of the indoor unit.
[0079] Frosting: Frosting on an air conditioner refers to the phenomenon of ice or ice forming on the indoor or outdoor unit of an air conditioner.
[0080] This application provides an air conditioning control method, apparatus, electronic device, and computer-readable storage medium. Specifically, this application provides an air conditioning control apparatus applicable to the air conditioning control method, which includes an air conditioning unit and a main control device for the air conditioning unit, such as a wall-mounted air conditioner, a floor-standing air conditioner, a window air conditioner, a ceiling-mounted air conditioner, or a recessed air conditioner.
[0081] In the current technology, with the continuous development of air conditioning and the continuous improvement of people's living standards, air conditioning products are becoming more and more widespread, and users have higher and higher requirements for the comfort of air conditioning products.
[0082] However, existing air conditioning control technology has low accuracy in judging the frosting status of air conditioning equipment and in performing defrosting. It cannot accurately determine whether the outdoor unit of the air conditioner has frosted or the specific condition of the frosting. This causes the outdoor unit to frequently enter defrosting mode or activate the defrosting function after frosting, which not only makes the air conditioner consume more electricity but may also cause the indoor temperature to fluctuate, seriously affecting the comfort of the indoor environment. Furthermore, after the outdoor unit frosts, it cannot quickly raise the indoor temperature and cannot achieve a good heating effect, resulting in a poor user experience.
[0083] This application provides an air conditioning control method, device, electronic device, and computer-readable storage medium. The method involves determining when the rate of change of the outdoor fan current reaches a first preset threshold, acquiring outdoor fan temperature information and indoor pipe temperature information; determining temperature difference information based on the outdoor fan temperature information, wherein the outdoor fan temperature information includes at least: the current outdoor fan temperature value and historical outdoor fan temperature values from a first preset time period prior to the current outdoor fan temperature value; determining a target operating strategy based on the temperature difference information, wherein the target operating strategy is an operating strategy to address frosting issues under the temperature difference information; and controlling the operation of the air conditioner based on the target operating strategy and the indoor pipe temperature information.
[0084] In summary, the air conditioning control method provided in this application embodiment can control the operation of the air conditioner based on the temperature information of the inner pipe and the temperature information of the outer fan when the change rate of the outdoor fan current meets the conditions, so as to deal with the air conditioner frosting problem, thereby achieving the technical effect of extending the air conditioner heating operation time and avoiding the air conditioner frequently entering the defrosting mode.
[0085] The following sections provide detailed descriptions of each example. It should be noted that the order in which the embodiments are described is not intended to limit the priority of the embodiments.
[0086] Please see Figure 1 , Figure 1 This is a schematic diagram illustrating a scenario of the air conditioning control method provided in this application. The air conditioning control system may include an air conditioner 100 and a main control device 200. The air conditioner 100 and the main control device 200 can communicate with each other in any way, including but not limited to signal communication via electronic circuits or wireless signals. The wireless signals can be computer network communication using the TCP / IP protocol suite (TCP / IP) or User Datagram Protocol (UDP). The air conditioner 100 can receive control signals from a remote control or control panel to perform a series of air conditioning functions such as cooling, heating, dehumidification, and dust removal. The air conditioner 100 can also receive instruction information sent by the main control device 200. The air conditioner 100 can perform corresponding cooling, heating, dehumidification, and dust removal operations according to the corresponding instruction information, such as the air conditioning control method in this application.
[0087] In this embodiment, the air conditioner 100 includes, but is not limited to, wall-mounted air conditioners, floor-standing air conditioners, window air conditioners, ceiling-mounted air conditioners, and recessed air conditioners.
[0088] Those skilled in the art will understand that Figure 1 The application environment shown is merely one application scenario of the solution in this application and does not constitute a limitation on the application scenario of the solution in this application. Other application environments may include those that are more specific to this application. Figure 1 The number of more or fewer air conditioners and air conditioners shown, for example Figure 1 Only one air conditioner or air conditioner is shown in the figure. The air conditioning control system of this application may also include one or more air conditioners and air conditioners for performing the air conditioning control method of this application. The specific details are not limited here.
[0089] In addition, such as Figure 1 As shown, the main control device 200 may include any hardware device capable of data processing and instruction sending, such as a CPU or microcontroller embedded inside the air conditioner; no specific limitation is made here.
[0090] It should be noted that, Figure 1The schematic diagram of the air conditioning control system shown is merely an example. The air conditioning control system and scenario described in this application are intended to more clearly illustrate the technical solutions of this application and do not constitute a limitation on the technical solutions provided in this application. As those skilled in the art will know, with the evolution of air conditioning control systems and the emergence of new business scenarios, the technical solutions provided in this application are also applicable to similar technical problems.
[0091] For details, please refer to Figure 2 , Figure 2 This is a schematic diagram of a scenario in which an air conditioner performs the air conditioner control method according to an embodiment of this application. The specific execution process of the air conditioner performing the air conditioner control method is as follows:
[0092] S201: Determine that the change rate of the outdoor fan current of the air conditioner reaches the first preset threshold, and obtain the outdoor fan temperature information and the indoor pipe temperature information of the air conditioner.
[0093] In this embodiment, the outdoor fan of the air conditioner is the outdoor unit fan motor, and the inner pipe of the air conditioner is the indoor unit coil.
[0094] As one possible implementation, the outdoor fan current information can be obtained by adding a fan motor current detection device, such as an ammeter or current sensor, to the outdoor unit of the air conditioner; the indoor pipe temperature information can be obtained by adding an inner pipe temperature detection device, such as a thermometer or temperature sensor, to the indoor unit of the air conditioner; and the outdoor fan temperature information can also be obtained by adding an outdoor fan temperature detection device, such as a thermometer or temperature sensor, to the electric fan control module of the outdoor unit of the air conditioner.
[0095] It should be noted that the acquired outdoor fan current information, indoor pipe temperature information, and outdoor fan temperature information can all be stored in the air conditioner's memory so that the processor can directly retrieve them from the memory when needed later.
[0096] Before determining that the change rate of the air conditioner's outdoor fan current reaches a first preset threshold and obtaining the air conditioner's outdoor fan temperature information and the air conditioner's inner pipe temperature information, the air conditioning control method provided in this application embodiment may optionally further include: obtaining the outdoor ambient temperature information of the space where the air conditioner is located; if the outdoor ambient temperature value indicated by the outdoor ambient temperature information is less than a fourth preset threshold, then obtaining the air conditioner's outdoor fan current information.
[0097] In this embodiment of the application, after the air conditioner is turned on, when it is running in heating mode, the outdoor ambient temperature information can be obtained in real time. When the outdoor ambient temperature value indicated by the outdoor ambient temperature information is less than the fourth preset threshold, the outdoor fan current information of the air conditioner is obtained.
[0098] As one possible implementation, when the outdoor ambient temperature indicated by the outdoor ambient temperature information is less than 7 degrees Celsius, the air conditioning processor retrieves the outdoor fan current information from the memory.
[0099] As one possible implementation, when the rate of change of the outdoor fan current is greater than 7 degrees Celsius, the air conditioner can be controlled to continue operating according to the current operating state.
[0100] It should be noted that the specific temperature values, temperature difference values, current values, time values, and threshold values in the embodiments of this application are all examples. The specific temperature, temperature difference, current, time, threshold, and other parameters can be set according to the actual operating conditions, and are not specifically limited in this application.
[0101] After obtaining the outdoor fan current information of the air conditioner, the air conditioner control method provided in this application embodiment may optionally further include: determining the outdoor fan current change rate based on the outdoor fan current information; if the outdoor fan current change rate is greater than a first preset threshold, then obtaining the outdoor fan temperature information and the indoor pipe temperature information of the air conditioner.
[0102] In this embodiment of the application, the external fan current information includes at least: the current external fan current value and the historical external fan current value before the third preset time period corresponding to the current external fan current value.
[0103] As one possible implementation, the current external fan current value and the historical external fan current value before the third preset time period are determined from the external fan current information, and the current difference between the current external fan current value and the historical external fan current value is calculated. Furthermore, the ratio of the current difference to the historical external fan current value is calculated to obtain the external fan current change rate.
[0104] Optionally, the third preset duration can be set to three minutes, or other durations, which are not limited in this embodiment.
[0105] As one possible implementation, after obtaining the change rate of the outdoor fan current, it is determined whether the change rate of the outdoor fan current is greater than a first preset threshold. If the change rate of the outdoor fan current is greater than the first preset threshold, the outdoor fan temperature information and the inner pipe temperature information can be obtained from the air conditioner memory.
[0106] As one possible implementation, if the rate of change of the outdoor fan current is less than a first preset threshold, the air conditioner can be controlled to continue operating according to the current operating state.
[0107] Optionally, the first preset threshold can be set to 5%, or other values, which are not limited in this embodiment.
[0108] It should be noted that, since the motors of external fans may have different models, resulting in significant differences in current, using the current difference and current ratio for judgment may be inaccurate. Therefore, in this embodiment, the current change rate is used for judgment.
[0109] S202: Determine the temperature difference information based on the temperature information of the external fan.
[0110] In this embodiment of the application, the outdoor fan temperature information includes at least: the current outdoor fan temperature value and the historical outdoor fan temperature value before the first preset time period corresponding to the current outdoor fan temperature value.
[0111] As one possible embodiment, after obtaining the outdoor fan temperature information from the air conditioner memory, the current outdoor fan temperature value and the historical outdoor fan temperature value before the first preset time period are determined based on the outdoor fan temperature information; and the temperature difference between the current outdoor fan temperature value and the historical outdoor fan temperature value is calculated to obtain the outdoor fan temperature difference information.
[0112] Optionally, the first preset duration can also be set to three minutes, or other durations, which are not limited in this embodiment.
[0113] S203: Determine the target operating strategy based on temperature difference information.
[0114] In this embodiment of the application, the target operating strategy is an operating strategy to deal with the air conditioner frost problem under the temperature difference information.
[0115] Optionally, after determining the temperature difference information, the air conditioning control method provided in this application embodiment further includes: determining the temperature difference value based on the temperature difference information; and determining the target operation strategy based on the temperature difference value being greater than a second preset threshold.
[0116] In this embodiment, a target operating strategy for dealing with air conditioner frost is determined based on the temperature difference between the current outdoor fan temperature value and the historical outdoor fan temperature value in the temperature difference information.
[0117] As one possible implementation, when the temperature difference is greater than a second preset threshold, the target operating strategy is determined based on the specific magnitude of the temperature difference.
[0118] As one possible implementation, if the temperature difference is less than a second preset threshold, the air conditioner can be controlled to continue operating according to the current operating state.
[0119] Optionally, the second preset threshold can be set to 5 degrees Celsius, or to other temperatures, which is not limited in this embodiment.
[0120] Optionally, when the temperature difference value is greater than the second preset threshold, the air conditioning control method provided in this application embodiment further includes: obtaining the current indoor fan speed and the current outdoor fan speed of the air conditioner; determining the temperature range corresponding to the temperature difference value; and determining the target operation strategy based on the current indoor fan speed, the current outdoor fan speed, and the temperature range.
[0121] In this embodiment of the application, when the temperature difference is greater than 5 degrees Celsius, the current indoor fan speed and the current outdoor fan speed of the air conditioner are obtained, and the temperature range corresponding to the temperature difference is determined; then, based on the current indoor fan speed, the current outdoor fan speed, and the temperature range, the target operation strategy is determined.
[0122] Optionally, the temperature range can be set as a first temperature range (5℃, 7℃), a second temperature range (7℃, 10℃), and a third temperature range (10℃, ∞℃).
[0123] Optionally, the air conditioning control method provided in this application embodiment further includes: if the temperature range is a first temperature range, then determining the target operating strategy as reducing the current indoor fan speed by a first preset value, or increasing the current outdoor fan speed by a second preset value.
[0124] As one possible implementation, if the temperature range is (5℃, 7℃), the target operating strategy can be determined as reducing the current indoor fan speed by one level (or reducing it by a certain value), or increasing the current outdoor fan speed by one level (or increasing it by a certain value).
[0125] Optionally, the air conditioning control method provided in this application embodiment further includes: if the temperature range is a second temperature range, then determining the target operating strategy as reducing the current indoor fan speed by a first preset value and increasing the current outdoor fan speed by a second preset value.
[0126] As one possible implementation, if the temperature range is (7℃, 10℃), the target operating strategy can be determined as reducing the current indoor fan speed by one level (or by a certain value) and increasing the current outdoor fan speed by one level (or by a certain value).
[0127] Optionally, the air conditioning control method provided in this application embodiment further includes: if the temperature range is a third temperature range, then the target operating strategy is to reduce the current indoor fan speed by a third preset value and increase the current outdoor fan speed by a fourth preset value.
[0128] As one possible implementation, if the temperature range is (10℃, ∞℃], the target operating strategy can be determined as reducing the current indoor fan speed by two levels (or by a certain value) while increasing the current outdoor fan speed by two levels (or by a certain value).
[0129] It should be noted that the first preset value is less than the third preset value, and the second preset value is less than the fourth preset value.
[0130] In this embodiment, the speed reduction level of the indoor unit fan motor can be reduced to two levels corresponding to the current fan speed, avoiding excessive reduction that could affect the air volume and indoor temperature.
[0131] Optionally, the speed setting of the outdoor unit fan motor can be increased to the highest fan speed setting of the outdoor unit.
[0132] In this embodiment, by reducing the current internal fan speed and increasing the current external fan speed, the frosting time of the outdoor unit of the air conditioner can be extended, thereby extending the heating operation time of the air conditioner and avoiding the air conditioner from frequently entering the defrosting mode.
[0133] S204: Control the operation of the air conditioner according to the target operating strategy and the internal pipe temperature information.
