[0002] Currently, variable-frequency air conditioners are gaining market share in the residential air conditioning market due to their energy-saving and comfort benefits. However, existing variable-frequency air conditioners require the compressor to run through multiple stages from startup to reaching the target frequency, resulting in a long time for the variable-frequency compressor to reach the target frequency. Specifically, existing variable-frequency air conditioners generally use a DC variable-frequency compressor startup method. To ensure oil return and stability during compressor startup, especially in low-temperature heating conditions where the compressor target frequency is high, the compressor runs through multiple stages during the frequency ramp-up process, and each stage runs for a certain period of time. As a result, it takes a long time for the compressor frequency to reach the target frequency, resulting in poor heating performance during the initial heating phase. Summary of the Invention

[0052] In the related art, in the household air conditioner market, the frequency conversion air conditioner gradually increases the market share due to its energy saving and comfort effect. However, the existing frequency conversion air conditioner needs to run multiple platforms from the start of the compressor to the target frequency, so that the time required for the frequency conversion compressor to rise to the target frequency is relatively long. Specifically, the existing frequency conversion air conditioner generally adopts a direct current frequency conversion compressor starting method. In order to ensure the oil return and stability of the compressor, especially in the low temperature heating condition, the target frequency of the compressor is high, the compressor will run multiple platforms during the frequency rising process, and each platform will run for a certain time. Therefore, the time required for the compressor frequency to rise to the target frequency is relatively long, thereby causing poor heating effect in the initial stage of heating.

[0053] Based on the above situation, the embodiment of the present application provides a frequency rising control method, a controller, an air conditioner and a computer readable storage medium of a compressor, which includes but is not limited to the following steps:

[0054] After the compressor receives the heating mode starting instruction, a target frequency of the compressor is acquired, and the compressor is controlled in a frequency increasing platform mode to obtain a target temperature parameter, wherein the target temperature parameter comprises an exhaust temperature parameter of the compressor or comprises an outdoor condenser coil temperature parameter and an outdoor environment temperature parameter; in a case where the target temperature parameter meets a preset frequency increasing condition, the compressor is controlled to enter a target frequency increasing platform close to the target frequency; and the running frequency of the compressor in the target frequency increasing platform is adjusted to the target frequency. The number of the frequency increasing platforms is multiple, and each frequency increasing platform corresponds to a running frequency and a platform time.

[0055] According to the technical scheme of the embodiment of the application, the embodiment of the application can control according to the comparison result of the target temperature parameter and the preset frequency increasing condition, and specifically, in a case where the target temperature parameter meets the preset frequency increasing condition, the embodiment of the application can control the compressor to directly enter a target frequency increasing platform close to the target frequency across levels, which is different from the control of the compressor to sequentially and step by step run multiple frequency increasing platforms in the prior art. Therefore, the embodiment of the application can shorten the frequency increasing time of the compressor in the low-temperature heating mode and improve the temperature increasing effect in the initial stage of heating.

[0056] The embodiment of the application will be further described below with reference to the drawings.

[0057] As shown in the drawings, Figure 1 Figure 1 is a schematic diagram of a system architecture platform for performing the frequency increasing control method of the compressor provided by an embodiment of the application.

[0058] The system architecture platform 100 of the embodiment of the application comprises one or more processors 110 and a memory 120, Figure 1 and takes one processor 110 and one memory 120 as an example.

[0059] The processor 110 and the memory 120 can be connected through a bus or other means, Figure 1 and takes connection through a bus as an example.

[0060] The memory 120, as a kind of non-transient computer readable storage medium, can be used to store non-transient software programs and non-transient computer executable programs. In addition, the memory 120 can include a high-speed random access memory, and can also include a non-transient memory, such as at least one magnetic disk storage device, a flash memory device, or other non-transient solid-state memory device. In some embodiments, the memory 120 can optionally include a memory 120 remotely arranged relative to the processor 110, and these remote memories can be connected to the system architecture platform 100 through a network. Examples of the above-mentioned network include but are not limited to the Internet, an intranet, a local area network, a mobile communication network, and a combination thereof.

[0061] ​Those skilled in the art can understand that Figure 1 The device structure shown in the above table does not constitute a limitation on the system architecture platform 100, and can include more or fewer components than shown, or combine certain components, or different component arrangements.

[0062] In Figure 1 In the system architecture platform 100 shown, the processor 110 can be used to call the compressor boost frequency control program stored in the memory 120, thereby implementing the compressor boost frequency control method.

[0063] Based on the hardware structure of the above system architecture platform 100, various embodiments of the air conditioner of the present application are proposed.

[0064] Specifically, the air conditioner of the embodiment of the present application includes but is not limited to an indoor unit and an outdoor unit, wherein the indoor unit is provided with a controller and an evaporator, and the outdoor unit is provided with a compressor, and the controller can include a processor 110 and a memory 120 as shown. Figure 1

[0065] Based on the above module hardware structure of the air conditioner, various embodiments of the compressor boost frequency control method of the present application are proposed.

[0066] As shown in Figure 2 Figure 2 is a flowchart of the compressor boost frequency control method provided by an embodiment of the present application. The compressor boost frequency control method of the embodiment of the present application includes but is not limited to steps S100, S200, S300 and S400.

[0067] Step S100, after the compressor receives a heating mode start instruction, the target frequency of the compressor is obtained, and the compressor is controlled by using the frequency boost platform, wherein the frequency boost platform includes multiple, each frequency boost platform corresponds to an operating frequency and a platform time;

[0068] Step S200, obtain the target temperature parameter, wherein the target temperature parameter includes the discharge temperature parameter of the compressor or includes the outdoor environment temperature parameter and the outdoor condenser coil temperature parameter;

[0069] Step S300, when the target temperature parameter meets the preset frequency boost condition, the compressor enters the target frequency boost platform adjacent to the target frequency;

[0070] Step S400, adjust the operating frequency of the compressor in the target frequency boost platform to the target frequency.

[0071] ​​Specifically, in the heating mode, the embodiment of the present application obtains a target frequency at which the compressor is to be operated and a target temperature parameter, which can include an outdoor condenser coil temperature parameter and an outdoor ambient temperature parameter, or an exhaust temperature parameter of the compressor; then, the embodiment of the present application compares the target temperature parameter with a preset frequency increasing condition, and in the case that the target temperature parameter meets the preset frequency increasing condition, the embodiment of the present application controls the compressor to enter a target frequency increasing platform close to the target frequency; finally, when the operation of the compressor in the target frequency increasing platform ends, the embodiment of the present application controls the operating frequency of the compressor to be adjusted to the target frequency. According to the technical solution of the embodiment of the present application, the embodiment of the present application can control according to the comparison result of the target temperature parameter and the preset frequency increasing condition, and specifically, in the case that the target temperature parameter meets the preset frequency increasing condition, the embodiment of the present application can control the compressor to directly enter a target frequency increasing platform close to the target frequency, which is different from the control of the compressor to sequentially operate multiple frequency increasing platforms in the prior art, so that the embodiment of the present application can shorten the frequency increasing time of the compressor in the low-temperature heating mode and improve the temperature increasing effect in the initial stage of heating.

[0072] It is worth noting that the target frequency increasing platform close to the target frequency refers to a target frequency increasing platform with an operating frequency close to the target frequency. For example, when five frequency increasing platforms such as a first frequency increasing platform, a second frequency increasing platform, a third frequency increasing platform, a fourth frequency increasing platform and a fifth frequency increasing platform are provided, and the operating frequencies corresponding to the first frequency increasing platform, the second frequency increasing platform, the third frequency increasing platform, the fourth frequency increasing platform and the fifth frequency increasing platform are sequentially increased, if the target frequency is greater than the operating frequency of the fourth frequency increasing platform and less than the operating frequency of the fifth frequency increasing platform, the target frequency increasing platform can correspond to the fourth frequency increasing platform.

[0073] In addition, it should be noted that the heating mode starting instruction can be generated by the user operating the control panel of the indoor unit, or can be generated by the user operating the remote controller, or can be generated by the user operating a terminal such as a mobile phone, or can be automatically generated by a sensor according to the indoor temperature.

[0074] In addition, it can be understood that the exhaust temperature parameter of the compressor, the outdoor ambient temperature parameter and the outdoor condenser coil temperature parameter can be obtained in real time by a temperature sensor. For example, the embodiment of the present application can set a temperature sensor at the exhaust position of the compressor to obtain the exhaust temperature parameter of the compressor, or the embodiment of the present application can set a temperature sensor outdoors to obtain the outdoor ambient temperature parameter, or the embodiment of the present application can set a temperature sensor at the position of the outdoor condenser coil to obtain the outdoor condenser coil temperature parameter.

[0075] In addition, it can be understood that the preset frequency increasing condition can be artificially preset.

[0076] In addition, as Figure 3 shown, Figure 3 is a flowchart of the compressor frequency increasing control method provided by another embodiment of the present application. In the case where the target temperature parameter is the compressor discharge temperature parameter, the step S300 includes but is not limited to the step S510.

[0077] The step S510 controls the compressor to enter the target frequency increasing platform adjacent to the target frequency when the compressor discharge temperature parameter is less than or equal to the first preset discharge temperature parameter.

[0078] Specifically, when the target temperature parameter obtained is the compressor discharge temperature parameter, the embodiment of the present application compares the parameter value of the compressor discharge temperature parameter with the parameter value of the first preset discharge temperature parameter, and controls the operating frequency of the compressor according to the comparison result. When the comparison result is that the parameter value of the first preset discharge temperature parameter is greater than or equal to the parameter value of the compressor discharge temperature parameter, the embodiment of the present application controls the compressor to enter the target frequency increasing platform adjacent to the target frequency.

[0079] In addition, it can be understood that the first preset discharge temperature parameter can be artificially preset.

[0080] In addition, as Figure 4 shown, Figure 4 is a flowchart of the compressor frequency increasing control method provided by another embodiment of the present application. In the case where the target temperature parameter includes the outdoor condenser coil temperature parameter and the outdoor ambient temperature parameter, the step S300 includes but is not limited to the step S520.

[0081] The step S520 controls the compressor to enter the target frequency increasing platform adjacent to the target frequency when the difference between the outdoor ambient temperature parameter and the outdoor condenser coil temperature parameter is less than the first preset temperature difference.

[0082] Specifically, when the target temperature parameter obtained is the outdoor condenser coil temperature parameter and the outdoor ambient temperature parameter, the embodiment of the present application calculates the difference between the outdoor ambient temperature parameter and the outdoor condenser coil temperature parameter, and then compares the difference with the first preset temperature difference, and controls the operating frequency of the compressor according to the comparison result. When the comparison result is that the first preset temperature difference is greater than the difference, the embodiment of the present application controls the compressor to enter the target frequency increasing platform adjacent to the target frequency.

[0083] In addition, it can be understood that the first preset temperature difference can be artificially preset.

[0084] In addition, if Figure 5 As shown, Figure 5 FIG. 4 is a flow chart of a method for controlling the frequency increase of a compressor provided by another embodiment of the present invention. The method for controlling the frequency increase of a compressor provided by the embodiment of the present invention further includes but is not limited to step S600.

[0085] Step S600: When the target temperature parameter does not meet the preset frequency-upgrading condition, the platform time of the current frequency-upgrading platform where the compressor is located is extended until the target temperature parameter meets the preset frequency-upgrading condition while the compressor is operating at the current frequency-upgrading platform, wherein the operating frequency corresponding to the current frequency-upgrading platform is lower than the operating frequency corresponding to the target frequency-upgrading platform.

[0086] Specifically, in the heating mode, the embodiment of the present invention will obtain the target frequency and target temperature parameters of the compressor, wherein the above-mentioned target temperature parameters may include the outdoor condenser coil temperature parameters and the outdoor ambient temperature parameters, or include the exhaust temperature parameters of the compressor; then, the embodiment of the present invention will compare the target temperature parameters with the preset frequency increase conditions. If the target temperature parameters do not meet the preset frequency increase conditions, the embodiment of the present invention will extend the platform time of the current frequency increase platform where the compressor is located until the target temperature parameters meet the preset frequency increase conditions while the compressor is operating on the current frequency increase platform.

[0087] In addition, it is understandable that, regarding the above-mentioned current up-conversion platform and the target up-conversion platform, the operating frequency of the target up-conversion platform may be higher than the operating frequency of the current up-conversion platform.

[0088] In addition, if Figure 6 As shown, Figure 6 Flowchart of a method for controlling the frequency increase of a compressor according to another embodiment of the present invention. When the target temperature parameter is the exhaust temperature parameter of the compressor, the above step S600 includes but is not limited to step S711 and step S712.

[0089] Step S711: When the exhaust temperature parameter of the compressor is greater than the second preset exhaust temperature parameter, extend the platform time of the current frequency-increasing platform;

[0090] Step S712: until the exhaust temperature parameter during the operation of the compressor at the current frequency-increasing platform is less than or equal to the first preset exhaust temperature parameter, wherein the second preset exhaust temperature parameter is greater than or equal to the first preset exhaust temperature parameter.

[0091] Specifically, when the obtained target temperature parameter is the discharge temperature parameter of the compressor, the embodiment of the present application compares the parameter value of the discharge temperature parameter of the compressor with the parameter value of the second preset discharge temperature parameter, and controls the operating frequency of the compressor according to the comparison result; when the comparison result is that the parameter value of the second preset discharge temperature parameter is less than the parameter value of the discharge temperature parameter of the compressor, the embodiment of the present application prolongs the platform time of the current frequency increasing platform until the parameter value of the discharge temperature parameter of the compressor during the operation of the compressor in the current frequency increasing platform is less than or equal to the parameter value of the first preset discharge temperature parameter.

[0092] In addition, it can be understood that the second preset discharge temperature parameter described above can be artificially preset.

[0093] In addition, as shown in Figure 7 , Figure 7 is a flowchart of the method for controlling the frequency of the compressor provided by another embodiment of the present application. In the case where the target temperature parameter includes the outdoor ambient temperature parameter and the outdoor condenser coil temperature parameter, the step S600 includes but is not limited to the step S721 and the step S722.

[0094] The step S721 is to prolong the platform time of the current frequency increasing platform when the difference between the outdoor ambient temperature parameter and the outdoor condenser coil temperature parameter is greater than or equal to the second preset temperature difference value.

[0095] The step S722 is to prolong the platform time of the current frequency increasing platform until the difference between the outdoor ambient temperature parameter and the outdoor condenser coil temperature parameter during the operation of the compressor in the current frequency increasing platform is less than the first preset temperature difference value, wherein the second preset temperature difference value is greater than or equal to the first preset temperature difference value.

[0096] Specifically, when the obtained target temperature parameter is the outdoor condenser coil temperature parameter and the outdoor ambient temperature parameter, the embodiment of the present application calculates the difference between the outdoor ambient temperature parameter and the outdoor condenser coil temperature parameter, then compares the difference with the second preset temperature difference value, and controls the operating frequency of the compressor according to the comparison result; when the comparison result is that the second preset temperature difference value is less than or equal to the difference, the embodiment of the present application prolongs the platform time of the current frequency increasing platform until the difference between the outdoor ambient temperature parameter and the outdoor condenser coil temperature parameter during the operation of the compressor in the current frequency increasing platform is less than the first preset temperature difference value.

[0097] In addition, it can be understood that the second preset temperature difference value described above can be artificially preset.

[0098] In addition, as shown in Figure 8 , Figure 8is a flow chart of the compressor frequency boost control method provided by another embodiment of the present application. As to the target frequency of the compressor obtained in step S100, it includes but is not limited to steps S810 and S820.

[0099] Step S810, obtaining the indoor environment temperature parameter and the outdoor environment temperature parameter.

[0100] Step S820, comparing the indoor environment temperature parameter and the outdoor environment temperature parameter, and determining the target frequency of the compressor according to the comparison result.

[0101] Specifically, the embodiment of the present application obtains the outdoor environment temperature parameter and the indoor environment temperature parameter, then compares the outdoor environment temperature parameter and the indoor environment temperature parameter, and determines the target frequency of the compressor according to the comparison result.

[0102] Specifically, when the temperature difference between the indoor temperature and the outdoor temperature is large, the target frequency of the compressor is correspondingly low; when the temperature difference between the indoor temperature and the outdoor temperature is small, the target frequency of the compressor is correspondingly high.

[0103] In addition, it can be understood that, as to the above-mentioned outdoor environment temperature parameter and indoor environment temperature parameter, the embodiment of the present application can be obtained by real-time detection through the temperature sensor.

[0108] Then, after the heating mode is started, the embodiment of the application controls the compressor to enter the first frequency-increasing platform.

[0109] Then, when the target temperature parameter meets the preset frequency-increasing condition, the embodiment of the application controls the compressor to directly enter the fourth frequency-increasing platform from the first frequency-increasing platform.

[0110] Finally, the operating frequency of the compressor in the fourth frequency-increasing platform is adjusted to the target frequency.

[0113] Specifically, before the compressor enters the first transition frequency-increasing platform, the embodiment of the application first controls the electronic expansion valve to act, so that the opening degree of the electronic expansion valve is within the preset opening degree range.

[0116] Exemplarily, when five frequency-increasing platforms are set, such as the first frequency-increasing platform, the second frequency-increasing platform, the third frequency-increasing platform, the fourth frequency-increasing platform and the fifth frequency-increasing platform.

[0117] The first frequency-increasing platform, the second frequency-increasing platform, the third frequency-increasing platform and the fourth frequency-increasing platform are the first four transition frequency-increasing platforms, and the fifth frequency-increasing platform is a target frequency-increasing platform. The target frequency of the compressor is higher than the operating frequency of the fifth frequency-increasing platform.

[0118] Then, after the heating mode is started, the embodiment of the application controls the compressor to first enter a first frequency-rising platform.

[0119] Then, the compressor is controlled to directly enter a third frequency-rising platform from the first frequency-rising platform, and then, when the target temperature parameter meets the preset frequency-rising condition, the compressor is controlled to directly enter a fifth frequency-rising platform from the third frequency-rising platform.

When TP≥TPs1, maintain the current operating frequency of the compressor until TP≤TPs2, then control the frequency to rise to the fifth-level frequency-increasing platform for the running time t6, and then increase the frequency to Fmax.
