[0040] The realization of the objectives, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. Modes for Carrying Out the Invention

[0041] It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0042] Existing air conditioner equipment collects environmental parameters such as ambient temperature and humidity, and controls the operation of the air conditioner's compressor, internal fan, external fan and other components based on the collected environmental parameters, thereby adjusting the air parameters in the working space, such as cooling, heating, humidification, dehumidification, etc.

[0043] However, existing air conditioners periodically control components such as the compressor, internal and external fans. For example, they collect environmental parameters every five minutes. Based on these changes, they output the operating parameters of the corresponding air conditioner components and control their operation. Setting the operating cycle too long can lead to excessive operation, such as overheating. Setting it too short can lead to over-frequent control, increasing operational burdens and hindering control efficiency.

[0044] In order to solve the above problems, an embodiment of the present application proposes a control method for air conditioning. By setting the control cycle to be variable, it can not only meet the purpose of rapid air conditioning, but also avoid excessive operation such as overheating, and can also reduce the operating burden of the air conditioning server.

[0045] 1 , a method for controlling an air conditioner according to an embodiment of the present application includes:

[0046] S10, obtaining the environmental parameters of the working space at the end of the last cycle of the air conditioner operation;

[0047] S20, determining the operating time of the air conditioner in this cycle according to the environmental parameters in the working space;

[0048] S30, obtaining the operating parameters of the air conditioner in this cycle;

[0049] S40, controlling the air conditioner to operate according to the operating parameters of the current cycle until the operation reaches the operating time of the current cycle.

[0050] During operation, the air conditioner has an operating cycle. Each operating cycle has a duration. At the beginning of an operating cycle, the current environmental parameters are obtained and the operating parameters for the current operating cycle are generated based on the current environmental parameters. The various components of the air conditioner are controlled to operate according to the generated parameters until the current operating cycle ends.

[0051] Since the air parameters are constantly changing during the process of adjusting the air in the working space after the air conditioner is started, when calculating the duration of the next operating cycle, the environmental parameters in the working space at the end of the current cycle can be obtained, and then the operating duration of the next operating cycle can be determined based on the obtained environmental parameters.

[0052] Therefore, in the embodiment of the present application, the operating duration of each operating cycle of the air-conditioning device is not fixed, and the operating duration of each operating cycle matches the current environment. The air-conditioning device operates according to the operating cycle designed in this way, which can not only meet the purpose of rapid air adjustment, but also avoid operating conditions such as overheating or underheating, and can also reduce the operating burden of the air-conditioning server.

[0053] In another embodiment of the present application, the end of the previous cycle may also be the start of the current cycle.

[0054] 2 , in the embodiment of the present application, step S20 includes:

[0055] S21, calculating change information of the environmental parameters in the previous cycle based on the environmental parameters in the workspace;

[0056] S22: Adjust the operating time of the air conditioner in the current cycle according to the change information of the environmental parameters in the previous cycle.

[0057] The environmental parameters within the aforementioned workspace include, for example, ambient temperature and humidity. By obtaining the current environmental parameters within the workspace and combining them with known parameters, changes in the environmental parameters within the workspace since the last air conditioner operation cycle, such as the amount of change and the rate of change, can be calculated. Based on this calculated change information, the operating time of the current cycle can then be adaptively adjusted, for example, by reducing the operating time or maintaining it unchanged.

[0058] In one embodiment of the present application, the environmental parameters in the working space include the ambient temperature at the end of the previous cycle. Correspondingly, the above step S21 includes:

[0059] The temperature difference is calculated based on the ambient temperature at the end of the previous cycle and the target temperature.

[0060] The above step S22 includes:

[0061] Based on the preset relationship between the temperature difference and the operating time, the operating time corresponding to the temperature difference is obtained, and the obtained operating time is used as the operating time of the air conditioner in this cycle.

[0062] A larger temperature difference between the current ambient temperature and the target temperature (set point) indicates that more cooling or heating capacity is required to quickly adjust the workspace temperature. In this case, frequent control is required, meaning the operating cycle should be short to avoid under- or over-temperature conditions. Conversely, a smaller temperature difference between the current ambient temperature and the target temperature (set point) indicates that less cooling or heating capacity is required to achieve the target temperature. In this case, frequent control is required, meaning the operating cycle should be long to avoid the operational burden of frequent control on the air conditioning server.

[0063] Therefore, based on the relationship between the preset temperature difference and the operating time, the operating time corresponding to the temperature difference obtained in step S21 is obtained, and the air-conditioning equipment operates according to the operating time, which can not only meet the purpose of rapid air conditioning, but also avoid operating conditions such as over-temperature or under-temperature, and can also reduce the operating burden of the air-conditioning server.

[0064] In another embodiment of the present application, the environmental parameters in the working space further include the ambient temperature at the start of the previous cycle of operation. Correspondingly, the above step S21 includes:

[0065] The temperature change rate is calculated based on the ambient temperature at the end and the beginning of the previous cycle and the running time of the previous cycle.

[0066] The above step S22 includes:

[0067] Based on a preset relationship between the temperature change rate and the operating time, the operating time corresponding to the temperature change rate is obtained, and the obtained operating time is used as the operating time of the air conditioner in this cycle.

[0068] After an air conditioner has run for an operating cycle, the greater the rate of temperature change, the more cooling or heating capacity is needed to quickly adjust the workspace temperature. In this case, frequent control is required, meaning the operating cycle duration should be short to avoid over- or under-temperature conditions. Conversely, a slower rate of temperature change after a cycle indicates less cooling or heating capacity is needed to ensure the ambient temperature reaches the target. In this case, frequent control is less necessary, meaning the operating cycle duration should be long to avoid the operational burden placed on the air conditioner server by frequent control.

[0069] The above temperature change rate Vt=|T(i)-T(i-1)| / H(i-1), where T(i) represents the ambient temperature at the end of the previous cycle, T(i-1) represents the ambient temperature at the beginning of the previous cycle, and H(i-1) represents the running time of the previous cycle.

[0070] 3 , in another embodiment of the present application, the environmental parameters include: the ambient temperature at the end of the previous cycle of operation, the ambient temperature at the beginning of the previous cycle of operation;

[0071] The above step S20 includes:

[0072] S23, calculating the temperature difference based on the ambient temperature at the end of the previous cycle and the target temperature;

[0073] S24, calculating the temperature change rate based on the ambient temperature at the end and the beginning of the previous cycle and the running time of the previous cycle;

[0074] S25 , determining the operating time of the air conditioner in this cycle according to the calculated temperature difference and temperature change rate.

[0075] As mentioned above, the temperature difference between the current ambient temperature and the target temperature, as well as the rate of change of the ambient temperature after the air conditioner has been running for a cycle, will affect the temperature control of the working space by the air conditioner. Therefore, based on the combination of the temperature difference between the current ambient temperature and the target temperature, as well as the rate of change of the ambient temperature after the air conditioner has been running for a cycle, the control frequency of the air conditioner is designed. This can enable the air conditioner to operate according to the operating cycle designed in this way, which can not only meet the purpose of rapid air conditioning, but also avoid operating conditions such as over-temperature or under-temperature, and can also reduce the operating burden of the air conditioning server.

[0076] In one embodiment of the present application, the above step S25 includes:

[0077] Based on the preset relationship between the temperature difference, the temperature change rate and the operating time, the operating time corresponding to the temperature difference and the temperature change rate is obtained, and the obtained operating time is used as the operating time of the air conditioner in this cycle.

[0078] In one embodiment, a relationship between the temperature difference, the temperature change rate, and the operating time is pre-set, such as the following two-dimensional mapping table, where Vt is the temperature change rate and Td is the temperature difference. This relationship table can be factory-set and initialized based on standard conditions. During the operation of the air conditioner, the relationship table can be dynamically adjusted based on user settings or the operating conditions of the air conditioner.

[0079] Td≥4.54.5>Td≥3.03.0>Td≥1.51.5>Td≥0Vt≥0.4511220.45>Vt≥0.312240.3>Vt≥0.1522440.15>Vt≥0.2446

[0082] S60, determining the operating duration and operating parameters of the first cycle of the air conditioner according to the current environmental parameters in the workspace;

[0083] S70: Control the air conditioner to operate for the first cycle according to the operating parameters.

[0084] During the first operating cycle of the air conditioner device, the current environmental parameters in the working space, such as ambient temperature, ambient humidity and other air parameters, are obtained. Then, based on the current environmental parameters in the working space, the operating parameters of the first cycle, such as compressor frequency, fan speed, etc., are generated; as well as the operating duration of the first cycle. Finally, the various components of the air conditioner device are controlled to operate according to the determined operating parameters until the operating duration of the first cycle is reached.

[0085] It is understandable that, in the above embodiment, the running time of the first cycle may also be set to a fixed value by default.

[0086] The air conditioner control method of the above embodiment is directly provided as a control module in the air conditioner device. Specifically, the air conditioner device includes a memory, a processor, and an air conditioner control program stored in the memory and executable on the processor. When the control program is executed by the processor, the steps of the control method of the above embodiment are implemented.

[0087] In addition, the air-conditioning control method of the above embodiment can also be used as a control device independent of the air-conditioning device, and realize the control of the air-conditioning device by interacting with the air-conditioning device.

[0088] The air conditioner control method of the above embodiment can be operated in the air conditioner automatic operation mode to design the overall control cycle of the air conditioner equipment; it can also be operated in the control of a specific operating component (operating parameter), such as designing the control cycle of the operating frequency of the compressor.

[0089] In addition, an embodiment of the present application also proposes a computer storage medium, which stores an air conditioner control program that can be run on a processor. The control program is called by the processor to implement the relevant steps of any embodiment of the above air conditioner control method.
